At least these days people don't have to obtain the corresponding region-specific version of Windows if they want to input a CJK language

[plain tusk]

I think modern windows generally has at least one pre-installed unicode font. I think it's a requirement for accessibility these days. May not look great but should still work

Linux is definitely the wild west when it comes to that stuff 😂

[raw jasper]

If you know how to fix CJK characters sometimes rendering "blurry" on linux, that would be nice..

[plain tusk]

Text rendering and audio seem to be two perpetual gremlins amongst linux OSes. Some seem to have fixed it better than others

[raw jasper]

Funnily enough, I've never had any audio issues

[plain tusk]

Some people are saying get rid of "opendesktop-fonts" which may have been preinstalled 🤷‍♂️

ehm, some kind of android emulator, that allows adb pass through or ways to automate?
nox and several others don't properly work, besides now they all seem to be also install junkware
bluestack I don't know for whatever reasons apps recognize that they're run on an emulator so they often do not properly work as supposed to
couldn't figured out why, online I saw something about changing config files, but its all back to 2014 or something, so deprecated

[burnt tendon]

yah, i admire the obsessiveness involved.

[plain tusk]

did you already rule out android studio? it's been a while since I used any android emulator, but I recall using that in the past and adb working fine. the docs even tell you to use adb to install and run apps https://developer.android.com/studio/run/emulator-commandline

[ebon dew]

I have a learn guide on some of the basics of the RA8875 and how it reads colors if you're interested. https://adafruit-playground.com/u/DJDevon3/pages/reading-pixels-from-the-ra8875-driver-board It's not currently compatible with the displayio library but if you're just doing some basic graphics the hardware acceleration from the RA8875 chip is extremely fast.

Scott once asked if it would work as a dotclockdisplay which I didn't try but might be worth giving a shot if you're using a fast MCU like an ESP32-S3 to try it without the RA8875 driver board. Setting it up as a dotclockdisplay will allow you to use displayio library with it.

It will likely be extreeeemly slow as a dotclock display but if you're only doing occassional small updates like weather or something that needs infrequent refreshing it might be doable.

It took me like 4 hours to fix this gif's missing frames. It's a divine loop now

Then downscale

This basically what i wanted for the DJ stream. Or some kind of audio visualizer for the neopixels

It seems dimmer on one end. I think the panels need external power when you exceed 2

[valid spoke]

Thank you that's very helpful

I have been reading a lot

[valid spoke]

Is this an array you made

[sturdy dawn]

No purchased panels

The 64x32 ones 2.5mm pitch

https://www.adafruit.com/product/5036

I changed the programming a little for the example so that it doesnt change images automatically. But buttons still cycle them

gimp is excellent for pixel art gifs

[plain tusk]

What do you mean by "external power"? The listing says you need to provide 5V/4A per panel. How are you powering it now?

At the very least, you may need to run thicker wires from the power supply to the "far end" of the display, but it may require additional power

[tardy badger]

Switch 2 drops tomorrow and I’m confident that all online stock will be sold out almost instantly

Well, drops at midnight eastern time

[raw jasper]

My understanding is that it has been pre-ordered to death anyway

Apparently, the new model does not use hall effect analog sticks either <_<

[dusty citrus]

why. googling out the error apparently the "solution" is uninstalling everything including vscode, clean up, then reinstall. Got in the "Configure Extension" point of https://www.waveshare.com/wiki/RP2350-USB-A

the board is surprisingly very small, pretty cute
also idk, it has a thick soldermask, feels less cheap

"and I’m confident that all online stock will be sold out almost instantly"

So you are admitting upfront that not enough stock was produced for the anticipated demand? Seems like a poor way to do business.

[tardy badger]

More like bots buying faster than humans can purchase

[hollow flint]

Please explain. Is it about it missing Nintendo exclusives?

[tardy badger]

No, Nintendo designs games around experiences vs visuals. Steamdeck is for people who like to play a broader range of games. Nintendo targets a much smaller audience with different interests

[hollow flint]

Odds are, there's a game available for the Steam Deck that's of the niche you're referring to. I guess if Nintendo games almost always fulfill the niche, it could be slightly more convenient than searching for the ideal game.

[kindred isle]

Digikey finally approved my account. And it turns out the lack of verification was what was causing me to be unable to order boards via DK Red. So now I'm all set to continue this project of mine.

Oh no, custom PCBs can't be cancelled or returned!

[hollow flint]

What would they do with your hypothetical returned custom PCB? Sell it to someone else?

[kindred isle]

It was sarcasm. Custom stuff is near universally unreturnable.

[raw jasper]

Nice!

Good luck with the PCB!

Hello everyone, I have been making a research for and specific board, the Adafruit can bus feather 2040 w MCP2515

My question is, this board can work with CAN FD?

[dusty birch]

Hi can someone help me im having problems with my matrix portal s3?

[ancient rivet]

in general, just ask, don't ask to ask, if someone can help they will eventually respond. also helps to try and pick an appropriate channel.

[ancient rivet]

not directly familiar with CAN FD - but is that something the MCP25625 datasheet would call out if it was supported? (seems like it's an extension to basic CAN?)

[umbral phoenix]

Doesn't look like the MCP2515/MCP25625 supports CAN FD. There are alternate parts, e.g., MCP2517FD/MCP251863 that do.

[ebon dew]

https://blog.adafruit.com/2025/06/05/live-coverage-ispace-makes-attempt-at-historic-moon-landing/

iSpace is live streaming the moon landing event https://www.youtube.com/watch?v=BVSMXQPeTcw which should be landing around 3:15pm EST

[ebon dew]

People walked out of the room. According to the mood in the room looks like it ate it on landing.

I'm not a rocket scientist but from my observation of the last second of telemetry it closed from 52 meters to -223 meters in less than 3 seconds then telemetry data stopped, at least on the public view screen.

They were about 1:43 off in their landing burn calculation. :/

[tardy badger]

Oof

[kindred isle]

52 meters from the surface, 187 kph
Conveniently, converting kph to m/s is close enough to 52 that it's just a matter of significant digits.

Just looking at the descent graph though, I don't think they missed their burn window, I think it failed to ignite one or more engines. Like, I too am not a rocket scientist, or any kind of aircraft expert in general. But that looks like an uncontrolled descent.

Oh, hold on, that's a log scale for altitude.

[dusty citrus]

Quite embarassing, but it's a long while since I last coded something 🥹
I don't quite get, why the onboard led is not blinking
the rp2350, is seen by the pc, but loading the code, doesn't make it blink

huh maybe it's the WS2812B-0807 that's not dumb, but requires a library

and it was indeed the library 😅

[weary fiber]

Man, making performant c++ as a noob is... hard

I'm trying to implement a binary heap that can reorder the top node, since std::priority_queue doesn't have that

but my algorithm for doing that is just as fast as popping the value off the heap & re-inserting it?

[dapper hatch]

There are a lot of nice 4" square 320x320 IPS displays on ali-express. They use SPI. Does anyone know if anyone has made a break out board with one??? I can't seem to find one. A lot of the classic 3.2" wide screen displays about. But the 4" square ones are the ideal size for my a little project. The PicoCalc uses one too.

[hollow flint]

I don't know, but Adafruit does make one such that instead of requiring SPI, it requires a special driver board (that they also make). Namely: https://www.adafruit.com/product/5827 and https://www.adafruit.com/product/5800

[thick wind]

It’s unlikely to find a breakout board for a raw display unless it either 1) is from the same manufacturer, or 2) has a standardized pinout. Usually for prototypes one would order a suitable ffc connector and solder to an ffc breakout board like https://www.adafruit.com/product/1325 or https://www.adafruit.com/product/1492.

[dapper hatch]

Thanks for the suggestions, I want to add a display to my macropad. The 480x480 looks a good but a bit other top for what I need. I have a pimironi presto so I could make that do the GFX work. But would perfer a single chip solution. I was uneasy with ordering from ali-express. Maybe time to make an account and if I can get one of these display working report what I find. 🙂

Tried to buy two of these, aliexpress says no. Moans about 'unusual network activity'. O well. 🙂 Maybe for the best.

[raw jasper]

If you are on a VM or using an "unusual" browser or sufficiently powerful ad/script blockers, aliexpress will refuse to work

[dapper hatch]

Most of them things. 😆 Linux, de-googled chrome and blockerNG on router. First shop site that has failed. Not a bad thing for my wallet. 😉

[raw jasper]

Yeah, it is not going to work then. It seems very insistent on doing all the tracking

[kindred isle]

Reminds me of when I tried to buy a printrbot eons ago during a massive sale. "The billing address you provided does not match the one on file with the credit card company." Buddy, I literally copied it off the credit card's web site after the first time you threw that error, and literally nobody else has ever had a problem with that address.
Call it a conspiracy theory, but I got the feeling that they realized that their sale was too good, but knew they couldn't cut it short. So they forced their purchasing system to throw legit sounding errors to stop people from buying.

[sturdy dawn]

That seems extremely high after you read the datasheet for the panels. Max wattage for a 64x64 p2 is 12W

[sturdy dawn]

But to answer, it has 5V and GND pins on the portal, which uses whatever adapter you put into the usb-c

Otherwise, i have a couple different options.

5v 10A brick with a barrel jack adapter on one end with +/- leads for the cables

Its sufficient to run 4 panels

The 15-panel array however uses a 300W supply. Probably overkill but that means ill never stress it

[rigid whale]

Does Adafruit make something the size of a QT Py RP2040 with blue tooth low energy?

I am new to all this so would it be best to just go to a larger feather or get a break out for the QT Py?

If you're using Arduino, this might work: https://www.adafruit.com/product/5700 - but not in CircuitPython until 10.0 is released I believe (and it's instock)

Somewhat ot, but there is no way to set up three finger tap on the touchpad and moving around as I was middle clicking and draggin? three finger tap does work, but as soon as I move them around I get this menu

I quite never found a way... just regot a laptop and the issue got out again

[weary fiber]

Unfortunately, most trackpads only recognize 3-finger swipes

mac-esque "three finger drag" usually requires a 3rd party program

I've heard good things about this though https://apps.microsoft.com/detail/9msx91wqcm2v?

If your laptop is more budget-oriented though, you may be completely out of luck. My school laptop had a trackpad that couldn't recognize 3-finger drags at a firmware level

Ah, yeah, fundamental support for it is dependent on implementing "Windows Precision Touchpad" stuff

[dusty citrus]

Yeah it works! love ya

Does the Feather S3 u.FL, when purchased from Adafruit, come with a u.FL antenna? It's $5 more for that variant, but I can't tell if it comes with an antenna

[plain tusk]

Hrm. I haven't purchased that specific board, but IIRC the last uFL device I bought from Adafruit included an antenna

I would sorta expect to see it in the pic with the header pins though 🤔
https://www.adafruit.com/product/5748

As an example, this one has antennas in the pics https://www.adafruit.com/product/5348

…but also says

Note: This board does not come with an onboard antenna, you need a uFL connector antenna such as the 2.4GHz Mini Flexible WiFi Antenna or a uFL to RP-SMA adapter The antenna is not included in purchase.

would the microphone max9814 be compatible with the grand central

[hollow flint]

I don't see why it wouldn't. I'm curious, what's your use-case that requires that many GPIO pins?

[gritty shuttle]

I am trying to make an earbud that goes into teh ear which uses two microphones one in ear and one out ear the out ear helps to block noise like a noise cancelation and the in ear listens to the humans breathing for heart and eerything else and for the microphone i was planning on using MAX9814

thats like a general gist of the project

Unless you already have a spare Grand Central M4 Express laying around, that board is very overkill for your project.

[tough thorn]

is it even possible to plugin jumper wires on the outside?

[hasty quarry]

Those are somewhat curious-looking headers

They don't look like machines or something either, but I'm not sure

[thick wind]

They’re surface mount female sockets. Yes it is possible, but it is a tight fit. Think plugging jumper wires into a breadboard right next to a pico.

[hasty quarry]

I see

[kindred isle]

Apropos of nothing, if you google "guthib" in an attempt to find github, you don't get a scam website. Instead you just get "You spelled it wrong."

[rotund canopy]

Any idea of the dashboard display technology in use here?

[kindred isle]

That's a curious one. First of all, it's clearly not using 7 segment characters. Interestingly, it also doesn't seem to be using 14 segment characters. Instead it's 12 segment. I mean, it could be 14 or 16, but the fact that neither the K nor the R are using the diagonal segments suggests 12 instead.
Beyond that, as far as the actual technology, part of me wants to say LCD due to the white on black characters with little emission. On the other hand, the way the character groups are packed suggests LED instead.

[rotund canopy]

Thanks for the input, this is my initial breakdown. I think it’s wrong based on what you’ve said?

[plain tusk]

Yeah it seems like an array of 2x5 5-character 12 segment displays 🧐

[rotund canopy]

Ohhhh thanks

[plain tusk]

Hmm, you might be right with your diagram though. Looking through the pics I'm not seeing spots where the horizontal lines are split in the characters 🤔

but I'm not seeing any shaped quite like that here https://en.wikiversity.org/wiki/Segment_display

[rotund canopy]

What’s the reasoning with the packing implying LED?

[plain tusk]

The fact that it's a 2x5 array of 5-char segments

But I'd also say the contrast is quite high if it was LCD, so I think LED is likely for that reason too

[kindred isle]

For me it's the fact that the edges of the displays are right up against each other, suggesting that the pins are on the back, not the edges.

Also, I got my boards. Apparently when you order from Digikey using DKred, you may get more boards than you ordered. I ordered 5. I received 9

Nothing soldered down, but everything lines up, so that's good.

I imagine that the reason for the extra boards is that it's easier to manufacture them in larger numbers, plus they don't do any electrical testing. So they just toss extras in. You should get at least the number you ordered.

[shadow siren]

When you do JLPCB they always give you 10 since I believe that is the minimum for small boards, they also electrically test the boards to make sure all traces are good and you can get the metal sheet with all the holes to use as a mask to spread solder paste.

hey JLPCB changed min order to 5 now, cool.

[kindred isle]

I went with Digikey, part as a test, and part for other reasons. They were cheap too. $1.50 per square inch. So for my order it ended up being only like $6 for what I actually ordered. I will make sure to test them before assembling. Perhaps in the future if I actually need assembly I'll go with someone else. This is good for prototyping now though.

[sturdy dawn]

So I created a pretty cool method of the Matrix rain for the LED panels. But first I'm going to make a video out of it and then I'll share the process here. Using gimp

This is just the 1.0 version. All pixels move at the same speed

[sturdy dawn]

It's kind of an old-timey method but it worked

65% is a bit high. I think like 30% would be better and get longer lines

The Matrix is 32 pixels high so it's exactly 32 frames long to complete a perfect loop

Hi Gang, I 'm a teacher looking for a quick hardware recommendation for a student. They have an Adafruit ADXL375 accelerometer breakout and they want a small Feather like board that has 1: a Quiic connector and 2: a way to log the sensor data on board. Any ideas on the simplest option(s)?

[solar kindle]

I think the only Feather with a Quiic connector and a microSD slot is this one: https://www.adafruit.com/product/5980

[sturdy dawn]

My time is probably better spent programming the Arduino how to do this instead of making gifs

[ember orbit]

Perfect. Thank you very much.

There should be a tracking number for the shipping company (USPS, UPS, etc). Take that tracking number and contact the shipping company to initiate a trace for a lost package.

[wooden schooner]

I know there are a lot of DigiKey customers on here so I'm wondering if anyone knows: they sent my stuff in a bubble mailer that says recyclable by store drop off. But the mailer is branded and just says DigiKey on it. I assume this means it's just not recyclable?

[blissful locust]

Hi I wanna learn about circuit boards, it's the first time I wanted to do this

[umbral phoenix]

@wooden schooner I think it depends on your locale and what's acceptable at various drop sites. Here, bags marked like that can be recycled at the grocery store with plastic grocery and similar bags, but they are supposed to have paper removed from what I understand (often challenging since labels are designed NOT to come off - so cutting them out is sometimes the only way to remove the paper).

[wooden schooner]

Oh, so "store" doesn't mean "the store you got it from"? That is incredibly confusing lol

Thanks 🙂

[hollow flint]

I don't believe DigiKey has any retail storefront.

Yeah, my assumption is their vendor had pre-made templates for the custom mailer and the template they used had a "recycle at store" icon

[plain tusk]

Happy to see you being so diligent about recycling properly 🙂 unfortunately plastic bags are basically unrecyclable, or at least not financially viable to recycle, so whatever store you bring it to is probably just going to throw it away anyway 😔

They didn't refund me last time 😦

[tardy badger]

They do extra just in case

[raw jasper]

Which platform is this?

[primal harbor]

JLCPCB

I'd be down for less than $500

But almost $750 is a lot

[tardy badger]

https://jlcpcb.com/help/article/us-tariff-policy-faq

[primal harbor]

Might try to cost optimize my design

[raw jasper]

Could also include customs handling costs?

[tardy badger]

It does

They prepay tariffs for you

[primal harbor]

Worth reducing smallest via size for cost benefit? It'd be like like $30 saved probably so more like $45 then ig

Could probably switch out a few parts to reduce cost also >_<

[tardy badger]

You could, yeah

[kindred isle]

Possibly my worst solder job ever. But it's the first time I've done SMD, the first time I've done ISP, and it works.
Nobody can take that from me.

[raw jasper]

Congrats!

[weary fiber]

There's a few SMD practice kits on amazon, which I used to learn

Honestly, I found them strangely fun & bought multiple to work on when I'm bored.

[kindred isle]

Yeah, I bought one and then just, didn't use it.
I will say that my first problem was that I put too small of a nozzle on the hot air side of my solder station. Probably also should have turned the heat up further. Like, I melted the solderpaste, but could really only do one side of the chip at a time.

I'm still pleased as punch that I not only did it, but I did it twice without destroying things. Yeah, I actually have two copies of that board (and enough bits to make a further four).
Also weird thing about programming them, I couldn't use the ATTiny toolchain that I did before. It refuses to burn the bootloader. I switched to another toolchain and it worked fine.

[terse lava]

SpaceX was working on a test of a reusable system on Wednesday in Texas. It is not very reusable anymore. 😆

[thick wind]

Accomplishments the one night my wife and son are both out of town:
Get my new 3D printer running.
Trim a thorn bush by the front door.
Stick a screen on an old iPhone box?

This is why I should not be left at home alone.

[thick wind]

Btw my first print last night is basically perfect. Out of box experience with Elegoo’s Centauri Carbon is absolutely amazing. Highly recommend for beginners as an entry level printer, probably higher than Bambu just for value.

Only question is when you can actually get one, I think they’re still filling preorders…

Printed in flash forge abs pro with no additional tuning of printer past its self checks.

[rigid whale]

Is there by chance anything like the featherwing tripler but for QT py size boards?

[umbral phoenix]

not as a product, even a (single) BFF proto would be helpful

[rigid whale]

Was thinking of stacking headers but I think that has limits to two boards.

If I wanted to stack two BFF onto the QT py sort of thing.

[umbral phoenix]

the BFFs go back-to-back, so you almost need to stack for that purpose instead of a tripler (unless it reversed the extra two layouts)

you can stack more than one as long as you don't need to access the top of the lower one, a lot of folks have stacked featherwings and this should be similar

but yeah, you need to get creative with the headers

[rigid whale]

fancy breadboard here I come 😛

[umbral phoenix]

here's something I tried a while back

electro-mechanically it's fine, just a little bigger than it really needs to be

[fair summit]

I have thought about this too. I suggest you use the contact form with the product suggestion choice: https://www.adafruit.com/contact_us

[rigid whale]

That is what I was initially thinking if there wasn't a tripler or doubler. Longer headers required it seems.

[rigid whale]

@fair summit Done. Thanks for the suggestion. 🙂

[ancient rivet]

@rigid whale another option if you're ok with ordering PCBs:
https://oshpark.com/shared_projects/5sXhVjRq
can also download the PCB files to order elsewhere

[weary fiber]

afaik adafruit sells half-height headers for just this sorta use case!

[fair summit]

BBF Squad from oshpark link above:

[weary fiber]

ahhhh nvm, they don't have stackable short-headers.

[ancient rivet]

^^ but ordered from JLC (which is how they are black)

[rigid whale]

Checked a couple sites for price quotes. Over $300 for a single board. Cheapest is an order of 6 for $220.

Will keep lookin of course but stacking headers and a bread board might be the cheaper rout right now.

[fair summit]

I don't understand. if you order from oshpark it's $17.60.

and it would probably be cheaper from jlcpcb

[rigid whale]

Was uploading the files and having it auto quote at Digikey.

[fair summit]

don't do that, order directly from oshpark or choose a cheaper service than digikey

[rigid whale]

Ok will do that haha.

[fair summit]

https://pcbshopper.com/

there is an "Order Board" button on "Actions" on the link above

And that $17.60 price is for 3 boards (the minimum)

[rigid whale]

Ok I see it thank you. Looked over at JLC and it's much cheaper with quotes. Thanks a bunch for the tips.

[weary fiber]

checked my oil and it was a touch below minimum 'cause 90k mile kia

Just gonna add a full quart and not think about possible damage incurred 🫠

[kindred isle]

I suspect like most consumer things, there's a degree of leeway. As long as the oil was at least reaching the dipstick, you probably weren't in any real danger.

[tardy badger]

Maybe they were trying digikey red?

[kindred isle]

Digikey red was pretty cheap for small boards.
As long as you don't mind the limited options like only red soldermask.

[plain tusk]

I kinda do 😭

[kindred isle]

Ah, well. Pity.

[rigid whale]

Red was not used.

[kindred isle]

I wonder what JLCPCB's policy is on SMD parts compared to PCBway. When I ordered some assembled boards from PCBway they pointed out that loading partial reels usually resulted in lost parts, so you got charged for like 20 wasted pieces for each SMD part you used. Resistors and similar, no big deal, but paying for an extra 20 microcontrollers? No thanks.

Huh. Near as I can tell, it's a flat $3 fee per "extended" part. That's pretty good if I'm right.

[sturdy dawn]

Had another idea for the matrix but this is more ambitious

Coding a stopwatch timer that can interface to a super Nintendo somehow. Maybe over Wi-Fi

I'd like to delete any sort of delay though

It can interface to the PC via USB to start a speedrun timer on "start game" signal but if i could send that signal to the matrix...otherwise wire up a foot button or something

Stopwatch itself seems pretty basic but just getting the input down. Circuitpython probably the way to go for beginner like me

These are really cool cartridges. You can also interface them to show like map data and stuff which you could send to the Matrix as well

[dusty citrus]

ok no found the full path by a global search... but still the compile/load thingy do not appear

[plain tusk]

VSCode probably doesn't know how. It all depends on what plugins you have and how the project is setup. Run the commands in the README instead

[dusty citrus]

You mean ^? I get another bunch of errors.
so far on vscode I have only the rp pico plugins, which set ups new projects nicely, but gives problems when importing this project

[plain tusk]

I think you'll need to go through the cycle of:

• google the errors you get
• find solutions for them online
• implement those solutions
• run the command again
• repeat

@fair summit Been awhile. Had to have a second knee surgery, tore my quadriceps, so I'm stuck on a walker for 6-8 weeks.
One of my theraphists commented that I had upgraded my walker and was it the jaguar model? Not shirking from the challenge I 3D printed a Jag hood ornament, designed a Jag front end with headlights, taillights, turn signals and a horn. I'm using a MetroMini which I had from my earlier pursuits and would like to add a sound board/MicroSD to play a few sounds for the horn (Ahh Ooga, LaCucaracha and We're in the Money from Caddyshack). Any suggestions??? Looked on the Adafruit site and couldn't figure which would give me best bang for the buck.
THANKS!!

[plain tusk]

Do you have pics!? Sounds awesome

As for an audio soundboard, I think best bang for your buck is a dfplayer, amplifier and speaker of some kind

Or if you find some mini speaker that has an aux in (and therefore its own builtin amplifier) that + dfplayer might be the simplest option

[raw jasper]

Wishing you a speedy recovery -- Good on you for not letting it all get to you and squeezing some fun out of the situation 🍻

[sharp plover]

I'll post some pics later today. Right now I'm using red PETG filament and silver PLA but have a spool of dark blue coming tomorrow, which better matches my walker color, except for the Jag, which is in shiny silver PLA. I used to DJ and had some broken fixtures. They had little headlight-like lens which were about 20mm and are perfect for this app.
I think it will be a hoot to play the Caddyshack horn sound from Dangerfield's car.
THANKS for the support!!!

[sharp plover]

Had a knee replacement in January, leg collapsed in March, got annoyed that my Ortho surgeon was taking too long to do anything, found a new surgeon in May and he got me into the hospital within 2 days of seeing the MRI, beggining of June......
So it's been a VERY LONG haul!

[raw jasper]

Glad you managed to find a way in! If you don't mind me asking, did the leg collapse because of some mishap during the knee replacement or was it unrelated?

[sturdy dawn]

Another cool use i saw for matrices at the arcade. Resurrecting old pinball displays

[sharp plover]

I had just switched from the walker to a cane and was pulling my slipper onto my left foot. I was standing on my right leg AND holding onto the back of my couch but the da*n right leg buckled. A large bulge formed on the outside of my right knee. I went to the surgeon and he said to just watch it for 4 weeks, which I did and it just kept getting bigger. At 6 weeks he told me to have an ultrasound done. I spoke to a friend who was an ortho nurse and she said I needed an MRI. Found 2nd surgeon who immediately set me up for an MRI. 2.5 centimeter tear of the quadriceps. Within 2 days I had the surgery.

Here's the hood for my walker. On the left is the Jag sitting on the hood. In the front are the little lenses with their holder. I Crazy Glue the color; red, white, orange; to the back of the lens, put a 330 ohm resistor on the anode, ground the cathode. The lens goes in the holder, the holder goes in the 3D printed mount. The holder goes in the hood bottom, on the right. The taillights go in the little silver holders. The speaker I want to use is 4 ohm, 3 watt, at the back of the pic. The Metro Mini is sitting on the hood and the battery holder (4 AAA) will power everything.
Of course I have to reprint everything in the dark blue PETG!
Apologies for this post length, starved for human interaction........
Best, Joe B

[fair summit]

Without considering the Metro Mini (which is a wimpy 328), I would suggest https://www.adafruit.com/product/5768

an alternative is a VS1053 sound board: https://www.adafruit.com/search?q=vs1053

Requiring no external microcontroller, there are the Audio FX Sound Boards: https://www.adafruit.com/search?q=audio+fx+sound+board

[sharp plover]

ALWAYS, a font of knowledge! Thanks @fair summit

[raw jasper]

Ugh, that sounds painful.. I'm glad you managed to expedite you getting medical attention! Your customizations look really neat; as they say, red makes it go faster :P

Also, no worries about the long message

[sharp plover]

I decided to forego the MetroMini and go with the RP2040 Prop Maker, I most always listen to @fair summit 's suggestions. Once I'm back on my feet I'm sure I'll come up with something to occupy my time with the RP2040. Maybe a mini robot.
BTW, red is my favorite color but it really clashes with the walker 🤪

Hi everyone. 🙂 So I 'discovered' neocities.org the other day. Seems to be a reincarnation of the 90's internet. 😎 Been going for a while. Has anyone here used it? They promise no adverting or AI. I've not made an account yet as I don't yet have the need to make a site. But thought some here maybe interested in it. Not sure how I missed this for so may years.

[hollow flint]

Another reincarnation of the 90's internet is I2P. This is because most websites that are accessible on it work without JavaScript enabled, and the throughput is generally slow.

[dapper hatch]

Thanks for the tip, will check it out. 🙂

Just found this site on neocities. It's like it's 1993 all over again. 🙂 (or when ever it was WWW started). https://lovelycornwall.neocities.org/

[weary fiber]

Neocities is great! It's a recreation of geocities, and nowadays people tend to use it like old myspace pages. A few friends of mine have set up their own, it's a lot of fun

Side note: Google has an easter-egg where just searching "geocities" turns all the fonts to Comic Sans

[dapper hatch]

That's cool

[hollow flint]

Although I'd strongly recommend downloading and running I2P itself, if you want to browse I2P casually before installing, you can use https://i2phides.me/about.html
Here's a categorized index of I2P sites to get started with: http://notbob.i2phides.me/ (note the lack of HTTPS, normally not a concern when using the actual I2P software)

[dapper hatch]

I may save that for another evening when nothing on TV. Seems like one needs to tread careful with something like this. Why I have never looked at the darknet, one wrong turn and you're in a heap of trouble. 😬

[solar kindle]

One thing that has always annoyed me is that "NC" on a part can mean either "not connected" or "normally closed".

[raw jasper]

hmmm.. In the context of an IC's datasheet I would without a second thought read it as "Not Connected". I'd only parse it as "Normally Closed" in the context of switches and maybe relays?

But I am sure there is the odd IC datasheet where the other, or maybe both meanings are used ;)

(Disclaimer: Not an engineer)

[plain tusk]

Yeah NC essentially only means normally closed when referring to relays/switches and not connected for ICs

[raw jasper]

(*normally closed ;) )

[plain tusk]

lol oops

that's what happens when what I'm thinking to say gets ahead of my typing 🙈

[raw jasper]

No worries! I normally try not to be That Person, especially given it was obvious what you were trying to say, but this time my inner pedant got the better of me....

That’s freaking sick

[dusty citrus]

I was seeing some implementation of wire guard on esp32... But they can't be used as an exit node/routing device... Is that right?

[vagrant wraith]

I have a question regarding ESP32 chips if anypne can help

Can TXD0 on the adafruit ESP32-S3 be used as a regular TX pin to transmit to an RS485 module

[plain tusk]

it might theoretically be possible but it would be severely bandwidth constrained

[plain tusk]

I'm not entirely sure what you mean by "regular TX pin", but at the very least you'll need an RS485 adapter for the different voltage

[vagrant wraith]

The adafruit feather S3 has 2 tx pins.
One that is gpio 39 and goes with the gpio38 rx pin
And another that is a txd0 which is a debug pin.

I have ended up finding some detail on it, and its just another tx pin but with startup noise

I got confused by the lack of a gpio value on the pinout

Im new to esp32 modules

[fair summit]

it's GPIO43. Often debugging printouts go to that pin. The noise you are seeing on startup is probably some bootloader serial output

[weary fiber]

Is "printing serial bootup logs to a specific GPIO" a common practice for board bootloaders like this? (teensies, adafruit NRF boards, arduinos, etc?)

[raw jasper]

logging to some UART tends to be pretty common in the embedded world, yes

[plain tusk]

In general it's good to have some way to get serial log output from these devices to diagnose what is going on, especially if it's bootlooping. Some MCUs have dedicated pins for that, while others are configurable so you can use it as something else, but may still output stuff before getting to the code where you configure it.

And many require certain pins to be high or low to boot normally (vs various other modes) or may default pins to high or low before getting to your code and how it's configured, e.g. https://randomnerdtutorials.com/esp32-pinout-reference-gpios/

[dusty citrus]

Just curious, how does adafruit make money? I mean does it come mostly from hardware sales, and maybe distrubutors partnerships?

[plain tusk]

I don't think it's publicly disclosed information, but I imagine it's primarily from hardware sales, yes

[vagrant wraith]

I came to know them from hardware and breakout boards.
So I assume from sale of those

The profit margin from something like a breakout board is pretty large

[fair summit]

yes, we sell physical things (mostly, aside from AIO subscriptions), and make money

[vagrant wraith]

Genuine question, why arent things like that part of the documentation?

[dusty citrus]

But you do also open source your designs... which end up being straight up cloned...

[vagrant wraith]

I assume the people who clone the design arent the target demographic.
The target demographic for such modules are people who do breadboard boards and so on,
people who don't want to or cant design their own pcbs

[fair summit]

it probably should be; for that particular pin, I think it's an oversight.

our hw is open source; people can clone the designs, but they aren't allowed to use our trademarks. The purchase cost of an Adafruit part pays for the extensive testing and support.

[vagrant wraith]

I really appreciate the open-source aspect of adafruit.
I was quite surprised honestly.
It saved me a lot of hours working on my own design.

And part of the reason why I chose to use the adafruit esp32 on my board on my pcb and not use an espressif board

[plain tusk]

While it ideally should be part of adafruit's documentation, it's also a good idea as a consumer/user to look into the documentation of the modules/components/etc. that are on the boards you're buying. This is covered in the ESP32-S3 docs themselves

[vagrant wraith]

Problem is with documentation like that is that I couldn't make the connection between io43 and io 38 both being used as TX.
I assumed that adafruit simply assigned io38 to be the main tx pin while db was something else.

Documentation like this is useful when you know electronics and know what to look at.
But when you dont have much background in electronics its things like that you expect to see in breakout board documentation.

Component documentation can be rather overwhelming

Now that I know what to look for Its really obviously outlined in the doc, but at the time I didn't really get what I was even searching for and trusted the pinout

Which makes me realize I should start writing documentation on my pcb design

[whole jacinth]

a lot of Adafruit's documentation seems targeted at beginners; intermediate and advanced documentation tends to happen if there Adafruit people make interesting projects that require that information

[vagrant wraith]

I assumed my question to be a beginner one,
Since I didn't know whats the difference between the two TX pins (one tx and one the debug txd0)

[whole jacinth]

yeah, that could probably be made more clear. please feel free to submit feedback on the learn guide where you see that pinout diagram

[plain tusk]

The docs say

This is the Debug TX (DB) pin. This is the hardware UART debug pin. You can connect this to a USB console cable in order to read the debug output from the ESP32 IDF. This is useful if you are writing software and need to see the low level debug output.
Is the confusing part that the other UARTs can be used differently?

[dusty citrus]

I also do but I can't quite ignore the loads of chinese manufactures delivering far cheaper knock offs.
maybe within the us market with tarrifs, it will fix the issue, but idk

[fair summit]

the knock-off mfrs provide little to no support, often don't test, and may do cost reduction (delete parts, use different parts, etc.). We know all that, and we still make our hw open source.

[vagrant wraith]

I was confused as to what the implications of two UART pins was and yes, that one of them can be a gpio pin with clean output and the other has the printput

So one I can use to.drive an nfet
And the other I cant

[plain tusk]

It looks like you actually can disable it (for all but download mode) by setting the right eFuse, but I think that's way too in the weeds for the general docs to cover

[lapis anchor]

I personally prefer purchasing Adafruit stuff over the clones due to some bad past experiences and wasting many hours on projects just to find out the clones were the problem. 🤷‍♂️

The two times I've had an issue with a product I purchased from Adafruit - they were resolved quickly and painlessly. 🙂 (I've had too many orders to count at this point 😁)

(also well worth the wealth of knowledge in the learn guides that are curated by Adafruit and the support of community in general on tested hardware)

[vagrant wraith]

Yeah I had a problem at work where we got into a wild goosechase over a code bug.
Only to figure out that 5 of the 6 arduinos were faulty.
And only the original non aliexpress arduino was working

All the others looped over or had faulty analog readings

[terse lava]

Oddly I don't see very many knock offs of Adafruit MCU boards at all. On the other hand, Chinese factories love to rip off other Chinese designers at Aliexpress such as Waveshare, LOLIN Wemos, and Lilygo stuff which is cloned like crazy.

[rotund canopy]

adafruit should mfg their own chips, the future is clearly towards indigenous ICs

[rigid whale]

[dusty citrus]

[dusty citrus]

what's for? signals?
that's what I find googling, I doubt that it interestes me in my use case, but just to be sure

thanks

[plain tusk]

Yes, higher speed signals need them to function properly

So are you using the USB just for power? Or "low speed" USB?

(This also might be better suited to #help-with-hw-design but idk)

[dusty citrus]

the high sped thing should not be supported on the rp2350
but thanks for the reccomandation.

I also want to share my frustation, I wasted a week to discover right now, that usb I was using to interface with the rp2350 was faulty.
I thought before that it may be the cable, but then excluded it because, it did load my stuff in it, I could see the board, but the serial was not properly working, so I excluded that it was a cable issue. Who knows what was on, if it was the cable I'd expect no data out of it

[plain tusk]

Which "usb" was faulty?

[vagrant wraith]

By the time shipping returned to my country.
The esp module I wanted went out of stock

How often is the stock restocked?

[vagrant wraith]

I guess ill have to buy the v2 instead of the s3 board.
Sucks but I dont think I'll matter much

[rigid whale]

They restock more frequently than I expected. Maybe a week for a fast turnaround. Maybe a month if the parts are in transit.

[thick wind]

Which esp module? Most espressif modules are fairly well stocked across multiple distributors.

[vagrant wraith]

s3

All the feather esp32 s3 modules are out of stock

[thick wind]

Any flash or psram requirements? The 8mb flash feather is available.

[vagrant wraith]

I need 5-7 units.
Only 2 available

[vagrant wraith]

Well looking at the pinout I cant use it since the pins are input only

[thick wind]

If you need a local distributor, there’s a list of those as well. https://www.adafruit.com/distributors

[vagrant wraith]

ill check the local distributers if there are any,
the digikey option is not availble on the local site for whatever reason

[vagrant wraith]

nope, they dont have esp32 modules unfortunatly

Just picked up Adafruit RP2040 Prop-Maker Feather with I2S Audio to use in a sound project I'm working on.I wanted to run the example code and play with it to get a feel for the board but I can't get Arduino IDE to talk to it. I am also having issue with the .h files, I have them in the main Adafruit library and where is the I2S.h file?
I'm using the Arduino IDE 2.3.6 on a MacBook Air running Sonoma 14.2.1. In the Boards Manager there is no Adafruit RP2040 board. The closest thing I could find is an Arduino RP2040 Nano Connect. Is this the right board to use? What am I missing? I checked for the board on the forum and just about everything was about running the audio files and a few posts about the NeoPixel stuff. But nothing on actual setting up the board.
Once I get a feel for the board I'm going to switch over to CircuitPython. Kind of wish the example was in CircuitPython......

[thick wind]

See https://learn.adafruit.com/add-boards-arduino-v164/setup for adding adafruit boards to the arduino IDE.

[sharp plover]

Thanks! I added the following:
https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
to the additional boards manager and now everything is happy. Until I get to the audio file conversion process which looks to be fun.

[sharp plover]

Whoops! I was just getting ready to play around with RP2040 and plugged it into my MacBook Air and none of the LEDs, transmitt/NeoPixel light up. I can connect to the board and see the data coming from the accelerometer in the console and the message that sound is being played, but there is no activity with any of the LEDs. I also reloaded the example program and still no LEDs. I moved the connection to my iMac and got the same result.
Finally I loaded the Blink example and got the red LED to blink, but nothing else. I reloaded the original program and still no LEDs. Other than having the board sit on a piece of anti static foam the board hasn't been in contact with anything else and I just plugged it in to start playing with the programming. I know when the board arrived the LEDs were lighting up and the NeoPixel was changing color.
Any ideas on what could have happened? I go this board directly from Adafruit so I know its not a knockoff. I was warned about only getting boards from Adafruit or DigiKey because of the poor quality of boards from other suppliers.

[plain tusk]

If you uploaded the blink example, you've overwritten whatever program was on there before that was changing the neopixel color. Where did you get the "original program" from to put it back? If it wasn't from the board itself, it might be the wrong one. What other LEDs are onboard that should be lighting up?

[sharp plover]

Before I tried the Blink program, the board was in the state I received it in. IIRC there was a green pixel that was blinking and the NeoPixel was cycling thru colors. I would have expected to see the transmit/receive LED blinking when I was uploading the programs but everything is dark. I got the "original program" from:
https://learn.adafruit.com/adafruit-rp2040-prop-maker-feather/prop-maker-example-2
I also tried the speaker which works just fine (says "hello" in 2 different voices), but the NeoPixel strip only lights up blue. The button turns the power off/on.

Be back later. Starting to get a little bleary-eyed. Thanks for the response and any suggestions you might have!😴

[plain tusk]

It looks like that program is designed to light up an external strip, but I don't think it changes the onboard LED. The "factory reset" program should (hopefully) be what was running on it though

[orchid perch]

hi, i need an recomendation. (it is not for my, i try to teach my girlfriend a bit python with shiny led stuff...) can someone tell me what small adafruit boards have jst connectors and battery connectors , also jst i think? i need board+small jst neopixel strip, battery. it should work without external powersource and be small. also usb connector for uploading programm. no soldering(no flying cables,it has to pass festival controll in an transparent bag, like it is part of the bag)

[plain tusk]

How long a strip, and how long does it need to run for? Battery power tends to go a lot faster than anyone expects/wants.

Another approach might be to get a usb battery pack. That way it isn't limited to being used just with this project

[orchid perch]

just small strip, not sure what is the smallest with jst, i think 30led, 0.5m. maybe there are smaller ones

and do not care if it just run for few minutes

[thick wind]

All of the adafruit feathers have battery connectors, but I don’t think any adafruit boards use a jst connector for neopixels. The JST connector typical of neopixel strips is a wire to wire connector if I recall correctly, so you’ll need to attach an additional pigtail to the board via soldering or screw terminal.

https://www.adafruit.com/product/5768 is probably as beginner friendly as it gets. Pair with a suitable battery and strip a flying lead for a solderless connection to the neopixel strip.

[ionic star]

^^ I've only done one project with these so far but I used that same feather and it was all about as easy as could be. Great documentation, easy trial-and-error with the neopixels, no need to worry about level shifting and the terminal blocks are really friendly. It's mostly just running one 12-pixel ring with various circuitpython animations, so a single 2200mAh battery lasts all day between charges.

[sharp plover]

No, I was using the screw terminals and circuit board prototype wiring to connect to the LED strip, which is BTW, not NeoPixel but pin compatible; 5V, GND, DIN.

[rustic basin]

I use a couple of different Qt Py boards with this BFF (https://www.adafruit.com/product/5645) to run one of the Adafruit NeoPixel strips with JST connector.

A new Thonny plugin brings AI programming to kids and classrooms. It uses a local LLM, so no credit card is needed.

https://github.com/tokoroten/thonny-codemate

[plain tusk]

I wonder how well that actually performs on an average or budget computer though

[sharp plover]

I use Thonny on the Mac so I don't know if it will even work. I didn't see any Mac specific info on GitHub

[plain tusk]

The underlying llama model does, and their readme mentions "Apple Silicon (Metal)" as a GPU option, so probably 🤷‍♂️

[sharp plover]

Thanks! Guess I should take more time reading the docs. Be nice to have an "assistant" making sure I'm getting the code right.😉

[wicked charm]

On MacOS + MacbookAir M2, there is a problem with the download screen for the recommended model, so it cannot be executed.
It seems to work well on Windows 11.
The code is returned in about 10 seconds using inference by the CPU of Rizen 7 3700.

[sharp plover]

Of course Macs suck hind teat......What a surprise! NOT!

On another note, doing a FlashErase and reload has me all the way back to a happy MP2040.
One last question (for the moment); has MU been deprecated??? I removed it from my Air as I got a message that MU was no longer being developed.

[hard estuary]

Mu will get two more releases, a legacy release and then the final version of Mu. More info: https://madewith.mu/mu/users/2024/12/10/retirement-plans.html

[sharp plover]

Thanks! I remember seeing something so rather than learn an app that was going away I started using Thonny.
Gonna go read the doc so I actually know what's going on.

[hard estuary]

they haven't met their Q1 deadline, so we'll see what happens

[sharp plover]

Just read the doc. But the Adafruit pages suggest using Mu so I'll be using it, with Thonny, until it does go away

[sharp plover]

using the code from

SPDX-FileCopyrightText: 2023 Liz Clark for Adafruit Industries

when I get to the following line:
i2c = board.I2C()

I am getting the following error:
Traceback (most recent call last):
File "<stdin>", line 54, in <module>
RuntimeError: No pull up found on SDA or SCL; check your wiring

HUH???? there is nothing on the I2C but the LIS3DH on the RP2040 board so why do I need pullup resistors??

[raw jasper]

FYI, you can enclose your code in three backticks so that it looks nicer.. You can even specify the language after the first three backticks to enable syntax highlighting; for example, this:
```python
print('Hello world!')
```

Renders as follows:

print('Hello world!')

[ancient rivet]

I2C requires pull up resistors on the SDA and SCL pins. you're either using the wrong pins or the resistors are actually missing.
what RP2040 board are you using?
what LIS3DH breakout are you using?

looks like a propmaker based on reading scroll back?

should work:

Adafruit CircuitPython 9.2.8 on 2025-05-28; Adafruit Feather RP2040 Prop-Maker with rp2040

[sharp plover]

I have NOTHING connected to the board other than the USB-C cable. I am really not interested (at this time) in anything other than playing .wav files and turning a bunch of generic LEDs on and off based on reading switches. That's all.
I was originally going to use a Metro-Mini but needed audio playback of 3 .wav files. I got a suggestion to use this board, so I've been looking at, or trying to, sample code from the code I noted above.

trying to run the code:
import board
i2c = board.I2C(), when I get to this line I get:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
RuntimeError: No pull up found on SDA or SCL; check your wiring

???????

[plain tusk]

Not sure if this is true or not (certainly sounds like an odd choice if it is 🤨) but this is saying you actually do need a device connected to I2C doing the pullup 🤔
https://www.reddit.com/r/adafruit/comments/yq2uxb/comment/ivzaua9/

[sharp plover]

First; thanks for taking the time to help me out!
here is the exact serial monitor input/output in Thonny:

RuntimeError: No pull up found on SDA or SCL; check your wiring

[ancient rivet]

weird. can you post a photo of the feather. top side.

[sharp plover]

so much for things being easier with this board. None of this I2C bus stuff is mentioned anywhere in the docs. According to the doc that @plain tusk posted a link for, Adafruit boards have these pullups on the boards with I2C busses. I NEVER had these issues with my other Feather boards. Is it possible that I got shipped a deprecated board?

[ancient rivet]

unknown. a photo of the top side of the feather would help to see if it's anything obvious hardware related.

[sharp plover]

here ya go

as I said I haven't connected it to anything. I have a couple of 9DoF boards and some I2C cables

[plain tusk]

If I'm reading the schematic correctly, not only does it have external pullups, but there should also be a LIS3DH hardwired to it 🤔

[ancient rivet]

correct

thanks for photo. looking... (nothing obvious though)

the lis3dh is here fyi:
https://learn.adafruit.com/adafruit-rp2040-prop-maker-feather/pinouts#lis3dh-accelerometer-3147714

[plain tusk]

@sharp plover do you have a multimeter? do you see a voltage on those pins? (presumably not, given the error, but might help confirm where the problem lies)

[sharp plover]

See thats whats VERY weird. When I ran the Arduino code, or if I put the original demo program on, I see values from the onboard lis3dh in ther serial monitor being updated. I'm going to hobble ove and see if I can pull a 9DoF board and STEMMA jumper. BRB

Yes, I do have several multimeters and a digital o'scope... BRB

[ancient rivet]

^^ even more weird

"original demo" = the factory reset UF2 from here?
https://learn.adafruit.com/adafruit-rp2040-prop-maker-feather/factory-reset#step-1-download-the-factory-reset-dot-uf2-file-3106950

[sharp plover]

here's the file I used:
adafruit-circuitpython-adafruit_feather_rp2040_prop_maker-en_US-9.2.8.uf2
It got the board back to. ligghting up the on board LEDs.
I just moved back to my workbench.I'm going to try the code withe the 9DoF board (LSM6DSOX + LIS3MDL) and see if the RP2040 still throws thw bus errors. Here's my setup:

[ancient rivet]

what's the "original demo" that works?

[sharp plover]

now the board doesn't throw errors:

Adafruit CircuitPython 9.2.8 on 2025-05-28; Adafruit Feather RP2040 Prop-Maker with rp2040
>>> import board
>>> i2c = board.I2C()
>>> i2c.try_lock()
True
>>> i2c.scan()
[24, 28, 106]
>>> 

and it shows the other I2C devices.
The original demo that works is the .uf2 file that I load using bootloader mode

[ancient rivet]

arduino does not do a similar check

it seems like maybe the pull up resistors on the feather are marginal

adding the 9DoF breakout added additional pull ups (on the breakout)

and those made the i2c bus OK

the pull ups on the feather are the two tiny ones here

[sharp plover]

Oh peachy! I just got the darn board. So dso I do a return?

[ancient rivet]

anything obvious there with a closer look?

[sharp plover]

nothing I can see even with my diopter. But I also have 76 year old eyes

[ancient rivet]

no worries. that'd classify as not obvious.

i think just replace it. but do you want to return it instead?

[sharp plover]

OK, here's the story. I had a knee replacement. 5 weeks in my leg collapsed and I tore my quadriceps. The folks at therapy told me I probably would need a better walker. So I got a new walker and being a general PIA I 3D printed a Jaguar hood ornament and figured why stop there since I can't do anything with this darn full length leg brace I designed and 3D printed a hood with 4 headlights using old diffusers from a LED DMX lamp. And then I added tail lights and designed roller switches which mount on the brake handles on the walker. And needed a horn, hence the audio, to play ah-ooga, La Cucaracha, and Rodney Dangerfields car horn from Caddyshack.
So at this point I'll probably replace it, just have to figure out how. In 2 months or so when I retire the walker I'll probably do a little robotic dinosaur for my granddaughter. I've already 3D printed abot a bozen creatures......

[ancient rivet]

cool. fun updates and mods! let's just replace the feather. that'll require posting in the forums here:

ok, replied

do this check again first thing when you get the replacement:

>>> import board
>>> i2c = board.I2C()

just to verify the replacement board is OK before attaching stuff, etc.

[sharp plover]

how does this work? will they send me a return label? will they just send a new board? kind of difficult getting around.

[ancient rivet]

not sure, but they'll handle it all via the email. typically they just send a replacement. no need to return the current one.

[sharp plover]

wow, that would be nice. Once again, thanks for the help. Didn't realize you were an Adafruit Admin!

[dense matrix]

I love adafruit, I also love the free coasters so I can roughly track how much ive spent

[sturdy dawn]

Best clock font ive found so far in .bdf format. Its called spleen-8x16

A lot of unused panel space, trying to find some tall fonts

[sturdy dawn]

I got a couple of those 😅

[sturdy dawn]

8x24 would be perfect

[ancient rivet]

are you using circuitpython for that clock?

[sturdy dawn]

Yes

Its an open ntp server

[ancient rivet]

another possible approach for the fonts is to custom make them via BMP and then use displayio tilegrid

[sturdy dawn]

There are converters but i need to find a good tall font like LED clock font

[ancient rivet]

generally more work, but gives you absolute pixel control of the resulting font render

so you can really tweak it for the display being used

[sturdy dawn]

Im noob at python

I grasp general coding concepts though

[ancient rivet]

ok, sticking with the BDF fonts is probably easiest for now

[sturdy dawn]

I like the arduino IDE better but this is less tedious

Once it compiles it uses low power

[ancient rivet]

here's an example project that uses the method described:
https://learn.adafruit.com/matrix-portal-room-co2-monitor/what-font

but it helps to understand displayio basics:
https://learn.adafruit.com/circuitpython-display-support-using-displayio/introduction

tilegrid in general is particularly tricky to grasp:
https://learn.adafruit.com/circuitpython-display-support-using-displayio/tilegrid-and-group

[sturdy dawn]

Spritefonts are cool but generally more taxing

[ancient rivet]

i went that route because i couldn't get any BDF font to be exactly like i wanted

[sturdy dawn]

Ive done some romhacking too 😀

[ancient rivet]

and i knew i only needed digits

[sturdy dawn]

Super metroid, its all hex pointers

[sturdy dawn]

If i knew how to code them

[ancient rivet]

oh, you know how to make custom BDF's directly?

[sturdy dawn]

No but that would be cool to just make it

[raw jasper]

I.. think fontforge supports bdf??

[sturdy dawn]

Im stubborn lol if i really want it

[raw jasper]

Not sure though, just going from memory

[ancient rivet]

https://learn.adafruit.com/custom-fonts-for-pyportal-circuitpython-display/overview

[sturdy dawn]

I spent like a month fixing that gameboy led matrix repo and miraculously got it to work

Like 240hz too

[raw jasper]

(FYI, I checked the docs, and fontforge does appear to support exporting to BDF.. It is a font authoring and manipulation software, usable through both a GUI and a python scripting interface)

[sturdy dawn]

Yeah i think .bdf is an old deprecated font format

Revived

[sturdy dawn]

Python doesnt like spaces right? I think thats what i was messing up in the cody.py file

Code**

Author noted to uncomment the line which declares the font variable but i think i forgot to delete spaces and just declared it at the top which worked. Plus makes it easier to change the font, right at the top of the code

I wanna figure out how to morph the colors so it cycles them like a solar lawn ornament

I also need to move the colons up about two pixels

[plain tusk]

Doesn't like spaces?

[raw jasper]

It has no problems with spaces in the middle of statements, but initial whitespace is syntactically significant

(Also, IIRC it will yell at you if you mix tab/spaces indentation in the same file)

[plain tusk]

You can in very certain circumstances mix spaces and tabs, but please don't

[raw jasper]

Oooo I am the ghost of misguided indentation decisions past, tremble before me 👻

Also, please don't mix tabs and spaces. My understanding is that using tabs for indentation is helpful for people who will read your code using a braille display (because each indentation level will render as a single character, as opposed to having to read through multiple spaces for each indentation level), as well as anyone who needs to adjust the indentation level on their side for readability, so please consider that when choosing between the two!

[sturdy dawn]

So that must be it. I forgot to take out the whitespace when I uncommented the line. Still like my method better so I don't have to search for the font line

[sturdy dawn]

LED name tags for work. A guy at work told me about someone in another location that had this, and my eyes lit up

That's just some seller on eBay. You could probably make it with stuff from Adafruit I'm sure

I could have it scrolling my name and position. Very cool

[raw jasper]

Please consider your co-workers with motion sickness before making scrolling nametags 🥴

[sturdy dawn]

Yeah a solid light probably better

Attach it to my beanie (I work in a cooler)

[raw jasper]

(FYI, I was not kidding)

Or consider using e-ink

[sturdy dawn]

They have this product for like the cost of those LED's. But I still wanna make it

[raw jasper]

(Also, another tip, since you are working with the stuff -- Avoid flashing lights et al in anything that may be viewed by anyone other than yourself, or at least check them with a tool like https://trace.umd.edu/peat/ first)

[sturdy dawn]

I noticed a lot of this stuff popping up lately. They have one. You can stick in your car window for like 20 bucks

Use it like a taxi sign for Ubers

[raw jasper]

Would an uber need a taxi sign? I thought the "car free" indicator was the app

(I don't use uber myself)

[sturdy dawn]

No idea I just thought of it lol. But yeah apps make that a lot easier

[raw jasper]

Said apps also enable the exploitation of drivers through assignment of "not-quite-employee" status

(no health insurance, etc)

[sturdy dawn]

Never actually used an Uber

There's just a cab company here that pretty much dominates the area. I always see them chilling in parking lots

Just get like a magnetized one like a volunteer firefighter. Thrown it on the roof line a cartoon character. You'd have to be legal though with LLC and insurance and all that

I actually found a repo that is basically the guts of the timer I want to make, but instead of being a stopwatch it's just a countdown from 30 minutes

Took me awhile to grasp the fact that you can't just put the path to the source file in your code. You need to create an object related to that source

Hence the name I guess...object oriented programming

I don't know which countries you're looking at, but https://data.census.gov/ should go into more detail than that.

[raw jasper]

What are you trying to do? It sounds highly unethical.

[dusty citrus]

it's an xy problem, I'll be more direct, not from the us, but I was looking where people about 20-25yo do reunion most, and a which time, so I can play with luck more efficiently. And also because of tourism, there's too many begpackers, who hang up for like a week and then disappear.

cause I need some friends, during the pandemic (although it's now endemic and everyone pretends there is nothing) 2-3 years in isolation,
then all day long at a job site. before that never really had friends due to mobbing. I just feel lonely af, but isolation has also made me too weird.

with protests and akin, which fail their original scope and function more for social reunions, although in groups, they're like clusterized, so it's actually difficult to bound

[raw jasper]

I.... think you are overcomplicating things. It would be much more sensible to find places where people gather with the intent to socialize by asking around (possibly at work, or at social media groups for your local area?), than try to do data science that potentially violates the GDPR.

It is indeed harder to make friends once you are out of school, but it is not impossible

[dusty citrus]

at school didn't really have much luck due to mobbing by the way I looked/subculture (somehow 10 year later, now the same things are popular across teenagers, idk if it's envy or something else).
Work, I prefer to avoid, cause they're all fake, and overall people will give you problems. as far with social medias... facebook groups all seem to have a lack of moderation, so it's all spam, instagram there are not groups functions that I'm aware of

[raw jasper]

By school I was mostly referring to college/university/trade school/etc.. High school tends to suck unless you are the sort of person that peaks in high school :P

I am not saying to try making friends at work, just to ask around for spots you can hang out at

[umbral phoenix]

depending on how densely populated your area is, there are often groups or clubs that meet about shared interests (like maker community), or even groups that are purely social without a niche focus

[dusty citrus]

ah, didn't go into any of those, barely made it out of high school, as for the city, it's a small city, the population is mostly old. Due to my experiences, the best would be about =>3yo younger/older people, just to reduce the luck of meting back the mob. I was thinking to leave the city by the mid 2026, over the uknown but 😕

[raw jasper]

If your past was so troubled, it may be best to look into completely leaving your country....

It's not like such organizations' sphere of influence stops at a single city

[umbral phoenix]

I interpreted mob to mean more like local bullies than organized crime(?) if the former, then even just to a larger city where it's more likely to find kindred spirits

[dusty citrus]

yeah that's the case, but it was/is so expanded that I get random uknown people annoying

[raw jasper]

That was a rather epic misreading on my side

[raw jasper]

Sounds like you have been traumatized... If you can afford it, a good therapist could help

Talk to text. Puts punctuation in the worst places

[raw jasper]

I remember using some version of dragon naturallyspeaking where you had to manually speak out any punctuation you wanted included in your autotranscribed text...

You could also fine-tune it to your accent, which you can't really do with the modern models

As for your issue, check that your include paths are correctly set up

[sturdy dawn]

That's funny that you mentioned the accent because when I watch subtitled videos online it totally ruins British accents

Russian accents. Good luck LOL

[raw jasper]

It also used to censor curse-words (punctuation is intentional to hopefully bypass the word filter), which sucks because it is infantiziling to people who need subtitles

[sturdy dawn]

All in time though. Computers are only evolving

[raw jasper]

In more recent videos it seems they don't do that anymore

Which is very good to see

Still, nothing will ever beat a professionally captioned video

If you want to see what a pro's work looks like re: captioning, take a look at any of the videos in this youtube channel:

https://www.youtube.com/@tomscottplus

[sturdy dawn]

Yeah I spent too much time on reels

[raw jasper]

No machine learning model can match that level of dedication

(at least, at the time of writing)

Things like different-colored text for different speakers, captioning of sounds heard throughout the video, etc

Also, at the time of writing, no widely-available machine learning model can work with multi-lingual video captioning

Things like foreign language lessons, bilingual speakers code-switching in the middle of a sentence (surprisingly common in practice), and so on, tend to break the models

Also I have seen the Japanese youtube autocaptioner frequently mess up homophones

😀

Yeah 0F is deadly

Surprisingly, the only time I've injured myself was bashing my arm on something even though I work with knives knock on wood

The band saw is probably the scariest thing about my job

[raw jasper]

TIL you cut meat with a band saw

(only ever been on the other side of the counter)

[sturdy dawn]

Lol yes for the steaks that still have bone in them. But it takes forever because they're covered in bone dust and you have to scrape it forever

[raw jasper]

ic

[sturdy dawn]

Like a tomahawk still has a bone on it

Or t-bone

[raw jasper]

Bone dust probably is not good to breathe in... hopefully you have a respirator?

is a bit of an occupational safety freak

[sturdy dawn]

I should wear one when I cut it

My Boss would probably make fun of me but he made fun of me for wearing a winter hat and I don't care. I'm not freezing

He also has the luxury of not being in the meat room for his entire shift

[raw jasper]

sends box of N95s -- there, don't want ya getting butcher's lung or whatever it's called

[sturdy dawn]

I actually bought a couple of those Cambridge masks from UK

Right when covid took off, but now they're proving more useful for the wildfire smoke

I'm not dogging masks. Just saying it's over now for the most part

While crossing my fingers cuz I don't want to jinx it

[raw jasper]

We did not get rid of the virus, it's circulating and messing things up just fine. The good thing is that regular vaccination can cut your chance of srs illness or death

[sturdy dawn]

I was a psycho

I admit. I didn't get the shot

But I admit that I was probably stupid for not doing that

[raw jasper]

And we also have medicine now... Not evenly distributed though

[raw jasper]

Oh new ones come out every year, just like the flu vax

[sturdy dawn]

That is good info

[raw jasper]

However, my understanding is that the US approval has now been limited because of you know what

[sturdy dawn]

Oh yeah things are getting crazy here

[raw jasper]

They update it to cover the newest strain though

[sturdy dawn]

My taxes are going to go up by $1,500 a year

And I make less than 50k

So there goes the tax return. Plus I pay more every week to withholdings

[raw jasper]

Theoretically, the optimal immunization frequency for SARS-CoV-2 with the current vaccine tech would be 2x/year, but most countries tend to offer it once per year

[sturdy dawn]

But see how I'm just complaining about how it affects me. That's part of the problem. I admit it

I knew it but I didn't want to believe it

I saw the charts before the law got passed

[raw jasper]

Anyway, these "cambridge masks" do not appear to be properly fitting respirators, but maybe they will be OK for light dust??? IDK, not OSHA

[raw jasper]

if only y'all's only issue was taxes...........

:S

[sturdy dawn]

Oh yeah it's much worse

I tune into Hassan once in awhile

No it's just a face mask

But they have charcoal and silver lined fabric

You kind of have to mash your hand over your face to make sure you get the full effect though with regular masks

[raw jasper]

Oh I just read world news, absolutely horrifying stuff is happening over there. Like, history book level of horrors

[raw jasper]

That indicates a bad fit. Would be worth looking into proper N95s

[sturdy dawn]

They claim it was designed by like UK department of defense

[raw jasper]

Everyone's face shape is different, so different models will have different efficacy for different people

Worth getting a few of each to try out

Also, if you grow facial hair, shaving can help improve fit

[sturdy dawn]

Oh yeah

I look so young when I shave though lol

[raw jasper]

And that is bad how?:P

[sturdy dawn]

People are like I don't know maybe about 30? And I'm like I'm 41 lol

Yeah I guess it's not bad

[raw jasper]

hah, congrats on winning the gene lottery

:P

[sturdy dawn]

It's weird because when I was like 13 people thought I was 19 and then when I was 30 people thought I was 19

I just became 20 years old and stayed that way for 20 years

I still wish I felt like I was in my twenties though 😆

I almost got this Pac-Man clock working but something is weird in the project

Somebody actually forked it and made it a playable Pac-Man game as well as a clock, and that one compiled and booted but it just kind of freezes

The crypto ticker I got working is cool but it runs for about 15 minutes and then freezes on one of the coins

[raw jasper]

BTW, speaking of vaxes, might be good to get your tetanus vax in order if you haven't, it lapses every 10yrs and can save you a trip to the ER to get anti-tetanus serum if you get injured

[sturdy dawn]

Oh yeah gotta reup those

[raw jasper]

Also check your measles status since apparently you guys are hellbent on bringing it back

[sturdy dawn]

Lol i have been vaccibated for that

I think at like 11

But yeah its crazy

Should check out uk lol

[dusty citrus]

I already work, I've found that private businesses and industries dont care about your degree, although they're usually located in the middle of nowhere. although I'm based in italy, a third word country which pretends to be a first world country, pay is low if you can get any job to begin with: as much I wish to earn more, cause money is not bad, it's pointless if I keep feeling void/unhappy

yeah maybe I should get consulting, but it's pseudoscience, they all say one thing over another. More about human touch/care starved than anything else, I'd guess

[raw jasper]

Eh, I would not call counseling pseudoscience... Maybe at the time of Sigmund Freud, but certainly not in the 2020s :)

Certainly it is not quantitative, but then again, neither is the human mind ;)

[silver shale]

Worth it
(helps if you know homestuck)

[rotund canopy]

I'm seeing all these cheap-ish thermal cameras for drones and for hunting optics, i wonder if i could get them from the same OEM these guys are using for cheapish

[strange hearth]

-# (ping me if u respond bc I don't check this server)

[sturdy dawn]

I just got the Pac-Man clock to compile for the portal s3 by declaring the "month day time" values in the header and then their values in the cwdatetime.cpp. I am like Goku every time it gives an error I get stronger

[sturdy dawn]

Now waiting to test it to give me something to get into later

[ancient rivet]

thanks for finding that. link should be fixed now.

[sturdy dawn]

It takes forever to boot but it does work

[sturdy dawn]

Overnight, it kept the minutes but not the hours

[sturdy dawn]

I think I found it. It's adding that double zero in quotes

Which seems to work for the minutes but not the hours

To get our function may be set up differently because I did pull this from a repo that wasn't using Arduino IDE

The getHour function**

The instructables was ported to Arduino IDE which was set up slightly differently than platform IO

I was on my break messing around but I'll compare the two functions when I get home later and see what's going on

[sturdy dawn]

They are different. One is using snprintf And the other is using strncpy

[sturdy dawn]

The autofocus just so happened to go along with the music 🤣

[sturdy dawn]

Ok i may have gotten addicted and ported the rest of the clock faces from the clockwise repo. Now I'm relaxing with diablo 1 town music

[brittle condor]

i need some feedback, I'm trying to learn micro soldering, i have a heart plate set at 220°C and then i use hot hair at 450°C, taking off components works great, no pads get ripped off, but soldering back on the components doesn't really work well... So far this is the best solder job I've managed, but as you can see not all pads have proper bridges. I've tried using a super fine soldering iron tip to try to clean it up, but it only made it worse. I'm trying to understand what's wrong with my technique, is it the kind of flux I'm using? is it the wrong solder (I'm using standard 60/40)? is it something else?

(I'm soldering on an old dead gpu)

[tardy badger]

In situations where I didn’t have a stencil for apply paste, I’d usually put enough solder paste onto the pads to get started with a bunch of flux (I like solid electronics rosin flux for this) and then I clean up with a chisel tip on a soldering iron to evenly get the pads soldered.

[brittle condor]

any particular solder paste you recommend?

all i have on hand is some terrible lead free stuff

so instead i just used some 60/40, put it on before the component eith the soldering iron and then i used hot hair to put the chip

[tardy badger]

For practice, bismuth based lead free is really easy to work with

[brittle condor]

why are you specifying "for practice"?

[rough fiber]

i have one of these panels but in 16x16 and in neopixels, wanting to do a wireless clock project, but i want to frame the panel

and i also have to make a grid like shape to make the pixels look better

otherwise blooming will ensue

[sturdy dawn]

I've seen that in the Tetris project. I don't think that they used a matrix portal, but they actually programmed Tetris right into the esp32 chip

You make two of them and they sink together and you can battle. It was pretty ambitious/ impressive

Trying to get this weather clock to work but still no luck. I'm gonna try an animated gif code.py that I found on adafruit's site, didn't have a git repo

It said he did something to get a better refresh rate than the Arduino project that was on there

Which is nice because you can just add gifs to the folder. Will the Arduino one you have to actually flash it back to to circuit python and add your gifs and then reflash the GIF player uf2

[rough fiber]

i can imagine, the 16x16 panels are very handy, and i've made a clock in the past, even bad apple with a dual buffer setup and esp32 tasks

tho i've ran out of microcontrollers right now, need to get a new esp32

and also buy a frame, but that's the least of my problems. I wonder what's the best solution to build a grid like array without it bending too much

guess at this point i'll have to 3d print it if i want it to not bend and such

[tardy badger]

Because bismuth paste isn’t super strong from a shock perspective and it doesn’t do well for designs that generate a lot of heat. Being good for practice means you can use it easily for getting better at particular techniques that are generally applicable to soldering SMT/SMD components

[brittle condor]

what would be the step after?

[tardy badger]

Get sac305 and a toaster oven

Or use your hot plate and hot air station. That is a bit harder but doable

[raw jasper]

Make sure to clearly mark said toaster oven as "soldering use only -- NO FOOD"

[burnt tendon]

Yeah, if someone tries to cook with it ... they'll be fuming.

[brittle condor]

lol already have the oven lol

also, as i said previously, I'm already using a hotplate + hot air setup, with such a thick pcb and with so much copper it would otherwise be impossible to solder

anyway thx

[patent badge]

Shw and Tell this evening

[sturdy dawn]

The circuit python gif player does work but it pulls it's delay between frames from the gif data so I would keep it over like 60ms

[plain tusk]

You might be able to have it decode the gif once into bitmaps, then loop the bitmaps smoothly. 🤔

[tribal yoke]

Hi everyone, I'm Tumini a UX /website designer with expertise in Framer. I'm excited to join this community and learn more about hardware development. I'd love to explore ways to apply my design skills to hardware related projects. If anyone needs help with UI/UX design or has questions about Framer, feel free to reach out!

[sturdy dawn]

Basically staring at code for hours because I'm too stupid to watch a tutorial 🤣

Finally got Mu, the IDE for circuitpython

I'm so ADD with all the projects I work on. It's hard to keep track of the working source code

Right now trying to get this clock to show the date as well as the time

I have no idea what server it's pulling the NTP request from but pretty sure it's Adafruit because it's using their NTP library

I think I like the ampm as opposed to watching the seconds waste away 😅

[sturdy dawn]

Got sick of staring at non color coded syntax

[umbral phoenix]

0.adafruit.pool.ntp.org, but you can change it in the init if you want

[sturdy dawn]

Ah ok. Ty. I could have sworn I had seen one that pulls time info from a particular ipv4 address, kind of like how you have static addresses for certain reasons

I wondered if that was some sort of standardized thing in routers, like an ntp server built in

But I suppose anything's got to be pulling info from somewhere

[umbral phoenix]

some routers have ntp (but yeah, they would be sync-ing to an external server)

[sturdy dawn]

I flashed a second one that I use a switch with dd-wrt without really knowing a whole lot about networking

It takes way longer to boot than the original firmware lol

[sturdy dawn]

So about 2 hours to add the date. Im a noob lol

Better

and THANK YOU to whoever recommended the REPL, helps a lot

[sturdy dawn]

A small step for me but it was the first time I studied the code and created my own objects with what I saw

[weary fiber]

some of my longest single debugging sessions have been just getting things to render properly on matrix displays lmao

I usually end up using adafruit's graphics library just "render" to a buffer in ram, then apply some sort of translation layer to a second buffer before displaying it out

I remember doing that for a breakout board that had horizontal row of 8x8s, but they were all treated as if each one was rotated 90 deg 😭

[sturdy dawn]

I've been trying to figure out how to use an alternative library to proto matter. I got the Mario clocks working which use it so I know it works on the portal? S3

Just to test the refresh rates

[quartz lagoon]

Joined this server once again after a year. 🙂

[warped lodge]

Hello, how do i ask a question to Adafruit about product recommendations?

specifically for esp32 and tmc2209

[thick wind]

Directly to adafruit? Best way to do that is to participate in “ask an engineer” livestreams and ask the question in the live chat.

Though for a general recommendation you can likely post your desired application here and get pretty good feedback.

[sturdy dawn]

They're no longer stocking the neopixels? I was thinking it would be cool to make a visualizer for audio with those

Oh never mind, I was looking at the wrong thing

They're expensive but I think it would be cool to build a display for mirroring retro games with it on the wall. I just don't have any subs or followers for these gimmicks LOL

Like instead of having a cam of yourself on the game you would just stand in front of the giant LED wall and play, looking towards the cam

I have all these ideas but I don't have any real estate to apply them

[icy needle]

The forums also gets you official support, but if it's like "I wish I could ask Ladyada this question..." then the #1280611628081221785 is the place to go, and it'll get a reply once answered on a wednesday live stream

[sharp plover]

Trying to find more in depth examples of the audio subsystem on th Adafruit RP2040 Prop Maker Feather. I can get it to ru.n the example program and play audio but can't get it to do anything else. Any suggestions??

[thick wind]

Better question would probably be, what do you want to do with this audio subsystem?

From a hardware perspective, it’s a max98357 I2S amplifier which could help find a few other examples. From a circuitpython perspective, there’s a couple of examples involving audio mixer objects to control multiple sounds. Arduino has its own audio frameworks as well…

[severe sonnet]

Trying to buy things online feels like trying to make a wish like if ypu don't know all of the terminology then you will be screwed so then I'm stuck here looking for stores that sell what I want but they are all in Russia or Canada,I don't know there is just very little in the US

[dusty citrus]

It's pretty ot, but is there any active comunity like reddit?
I'm finding that in a lot of subs mods have gone mental with bans
There is lemmy, but it is just as much used. Quora is garbage.
forums that are topic specific are either dead or lack moderaton (as full with spam)

[sturdy dawn]

I feel this comment. I have wasted a lot of money buying the wrong things

And all the way back to like the '90s. I remember the internet playing on that vulnerability. You search for how to do something and it gives you like a link to some software that's paid. And really it's just a simple fix that didn't need anything

Most of us were too smart to fall for that stuff, but I'm pretty sure my parents fell for a couple scams

We were a mute the commercials type of family growing up so we could see through the gimmicks pretty easily

But like late '90s computers, exploded and Banks were giving credit cards to people like crazy. So pretty much everybody had a computer at that point

I remember we actually had keyboarding in computer class in 1997. My mom had this electric typewriter and I would practice at home

[raw jasper]

To be fair, everybody can fall victim to scams given the right circumstances

[sturdy dawn]

Yes

[raw jasper]

One may be too tired to see the signs, or just too desperate

[sturdy dawn]

Or just not computer literate enough. I remember installing so many softwares and it was just basically a virus

[raw jasper]

I was thinking of scams beyond computers. Things like falling for medical quacks, etc

[sturdy dawn]

Oh God yes

I remember the theories of vaccines causing autism starting around early 2000s and it just spiraled into 20 years later. People are refusing the shot

[raw jasper]

Oh that's just plain ableism

[sturdy dawn]

Yeah, I can't blame it

[raw jasper]

"I'd rather my kid be dead than autistic"

Statements dreamt up by the absolutely deranged

[sturdy dawn]

I had thought about it back then but I was like well. I got all the stuff I needed to go to school which was mumps measles rubella

And others I think when I was younger

[raw jasper]

I've gotten the whole gamut (have the paper records from when I was a kid). Keep getting new ones as they become available. Turned out just fine.

Am disappointed my cell phone reception did not improve after getting the COVID vaccine though :P

[sturdy dawn]

Oh yeah the 5G

[raw jasper]

Look, cellphone reception is absolutely dreadful where I live! I could use that reception boost! :P

Especially if it's 5G! :>

[dusty citrus]

yeah the only time that I got through a escam, I was going through psychosys 😕

lost about 150euros, a bunch of hair, and some personality I guess

[terse lava]

I believe there is a new vaccine coming out next year that is a combo Flu and Covvid shot (read about it in the Boston Globe newspaper earlier this summer). Hopefully they turn up the 5G reception on that one. 📡

[midnight willow]

Does any one know if the Adafruit HX711 24-bit ADC for Load Cells / Strain Gauges (https://www.adafruit.com/product/5974) and Adafruit NAU7802 24-Bit ADC - STEMMA QT / Qwiic (https://www.adafruit.com/product/4538) can measure this Sparkfun load cell: https://www.digikey.com/en/products/detail/sparkfun-electronics/10245/5843757. The HX711 board is more expensive (and less available) and both boards seem to have similar wiring.

I'm looking for a load cell that's cheap and would work for a scale to measure human weight.

[karmic atlas]

can anybody tell me the part number for the cable connector ?

the one on the left with the load label

[raw jasper]

Sorry you went through that :(

[raw jasper]

Yeah, moderna (among other companies probably) is looking into it and has had some promising results so far, though, given the current climate, my understanding is that it is considered unlikely to be approved in the US

[sharp plover]

Pretty simple. I have 3 .wav files:
0.wav @ 22050:16 bit, 209 KB
1.wav @ 22050:16 bit, 131 KB
2.wav @22050:16 bit, 99 KB
My program has 3 pushbuttons. When I press one of those buttons I would like to play the associated file, once for each press. That's it.
I'm also throwing an error:
I2S_BIT_CLOCK is in use
Any ideas or links that you mentioned?
Thanks

[lapis anchor]

~~those connectors are meant for bare wire - they have a spring contactor in them, you push the indent on the top to insert/remove the cable 🙂 ~~ thought you were looking for an actual connector to use with it, not the connector itself 😛 should be this part https://www.digikey.com/en/products/detail/wago-corporation/2060-472-998-404/15790795

[karmic atlas]

Thank you very much for the help! I am using another kind for a project and i wonder if I can upgread

[lapis anchor]

potentially. not sure if the layout is the same, Amphenol is a quality brand. just curious what you're trying to "upgrade" about it? (more current carrying? easier to use?)

[karmic atlas]

I am having troubles of choosing connectors for my project. In terms of ease of use. I think the spring loaded ones would be better because the Amphenols are hard to disconnect since you need some kind of tool to put in the little hole and rotate

The electrical characteristics i can workout from the datasheet

I will remake this board anyway, the footprint will be adjusted

[lapis anchor]

hmm yeah that's a fair point, I've always liked the WAGO stuff but one concern I have with cable connectors like that is putting force on the PCB if the surrounding area isn't supported properly, higher chance of breaking a trace due to flexing the PCB for example. (i.e. supported w/ standoffs or similar) but I'm also not a mechanical engineer or PCB designer, so may not be a warranted concern 😄

[sturdy dawn]

I added 12 mm to each dimension for the acrylic panel so it would go into the extrusion slots by 6 mm

[raw jasper]

I just felt my body turn itself to ash as I read a one-star review of a landline/POTS phone justified by the buyer having "connected it to the internet" (presumably to an ethernet jack?) and being unable to place a call

[terse lava]

Anyone else having issue with this discord showing everything as new again? Not happening on other servers I am on, but the past day or so everytime I come in here, all the channels are marked as having new content when there isn't anything new since my last peek.

[hard estuary]

That's because someone flooded the server with spam, which we remove, but it still shows the channel with new updates

[kindred isle]

I still like the review I saw of some 2 part epoxy resin where the buyer complained that it ruined their project and nearly burned their house down...
After they mixed it with some other random 2 part epoxy resin they found under their sink.

[raw jasper]

Are you also @robust steeple and @tall kiln ?

If so, why do you keep making sockpuppets?

If anyone was interested in what "you" are offering, they would have gotten back to you. LLM-"rewriting" and re-posting the same text under a different handle is not gonna help

[raw jasper]

Of course mixing random chemicals is always very unwise, but I wonder how they made the epoxy's polymerization that violently exothermic

[kindred isle]

I suspect it was at least a bit of an exaggeration, but from what I understand of the process, it is generally somewhat exothermic to begin with. Not knowing the details, my guess would be that one of them was quick setting, and ended up turning into extremely quick setting when mixed with the wrong chemical. So instead of generating a moderate amount of heat, it generated huge amounts of heat.

[raw jasper]

Who knows? What is good is that nobody ended up getting hurt, and hopefully that person got a much-needed life lesson

[kindred isle]

Hopefully

[raw jasper]

(Also, AFAIK, polymerization is always exothermic because the formed bonds in the polymer should lead to it being at a lower energy level than the monomer for the reaction to occur and the product to be stable)

[raw jasper]

To be fair, I am just feeling strange that we have crossed the point where a person can be old enough to be able to make online purchases and leave reviews, while having never acquainted themself with a landline telephone

Which... makes sense! Very few individuals have landlines now

(Also, most "landlines" are not actual landlines but barely disguised VoIP, but that is a whole other can of worms)

[kindred isle]

You're old. I'm old. We're just going to get older.
I played a game recently that had a whole section of instructions on using a rotary phone. Yes, it was thematically appropriate as the game involves a lot of very detailed instructions, but at the same time I would not be at all surprised if lots of their playtesters genuinely had no idea how to use one.

[raw jasper]

You are probably older than me :P -- I used a rotary phone once when I was 5. Still, I do know how to dial one!

But agreed.. I worry that I'll reach a point where I'll no longer be able to tell generated photos apart from real ones

[sharp plover]

Heck, I'm ancient. Have you ever used a phone where you had to a depress the cradle a few times to get an operator who you told the number you wanted to connect to and she plugged a jumper on a switchboard and connected you. Of course an operator could listen if they were nosy.

[raw jasper]

Haha, no, I've only seen that in movies.. Speaking of ancient phones, I think you'll appreciate the connections museum youtube channel, if you have not come across it already

https://www.youtube.com/@ConnectionsMuseum

[sharp plover]

Very cool b ut definitely not an afternoon drive to get there. I'm down by the border in AZ\

[raw jasper]

I live in a whole other continent -- I just appreciate their work via youtube

[kindred isle]

Yeah, I'm not that old.
But now I'm gonna sound old and cranky. Work is phasing out SMS 2FA. Gotta install Okta Verify.
Grumble grumble, I make it a point to not have work stuff on my phone.

[raw jasper]

You should ask them for a work phone

Things could get real sticky if the corpo gets in legal trouble and your personal device becomes part of discovery

[kindred isle]

Checking the instructions, apparently I don't have to enroll my phone in device management. So at least there's that.
Also amusing thing, the instructions show a QR code, but someone drew an X over it. Unfortunately, knowing what I do about QR codes, it's probably still scanable given the available error checking.

Ah, nope. Saved by image compression and scaling. Unless you really wanted to reconstruct it, you're not scanning this easily.

[raw jasper]

The one case where word mercilessly mangling images is helpful! :P

[kindred isle]

Well this was probably to be expected.
"Okta error: API call exceeded rate limit due to too many requests."
I bet everyone else is trying to do this now too. I'll try later.

[raw jasper]

Now I am wondering what the benefits of using okta are, compared to a traditional TOTP

[kindred isle]

No clue. But I would have preferred to have been able to just add it to my Google authenticator.

Well, actually I do know one advantage. They can do a push notification so instead of typing in the code, you just confirm the login.

[raw jasper]

hmmm... I wonder how they defend against fatigue attacks

[kindred isle]

Perhaps disable off site login after X number of rejected logins. When you're connected directly to our network, you don't need any 2FA, it's only for off site logins.

I don't know enough details about the system to know if that's even possible though.

[hollow flint]

It has support for device-bound passkeys on hardware security keys: https://www.yubico.com/works-with-yubikey/catalog/okta/

[karmic atlas]

yeah... SMD connectors do not like stress. But you get the convenience of assembly.

[somber spindle]

Okta is in the loop, therefore fatigue attacks are not possible

it's not TOTP, it's something else

Yo hi 👋 🙂

[terse lava]

Over in the WLED server that have been trying out a way to combat spam-bots. They implemented a "honeypot" channel that if you post anything to it you are automaticlly banned and all posts from the last 7 days are removed. Of course within the honeypot channel that have big bold text warning everyone NOT to test it, they will get banned. Since bots tend to post to every channel on a server, they of course will post there, ban themselves, and have all their posts removed.

[rapid geode]

so i got a spacebar 3d printed in titanium...

mmm

[terse lava]

Why not solid gold. I mean if you are going to go metal, go big!

[rapid geode]

....

[terse lava]

And no love for the one on the right?

[rapid geode]

....

[kindred isle]

I wonder if it would be possible to 3d print silicon.
I want silicon dice. The problem is that it's incredibly difficult to machine silicon. It tends to not chip, but just straight up fracture.

[rapid geode]

it cleaves

probably can diamon grind it

definitely cant print it that i know of

[kindred isle]

Is there a technical difference between cleave and fracture?
All I know is that if you try to machine it, it likes to just split instead of letting you cut little chips off like with steel or similar.

[rapid geode]

cleaving is splitting on predefined planes in the crystal structure. diamonds cleave, vs ruby which you grind.

[kindred isle]

Ah.

I do know it can be machined, but if I recall you have to use a very small bit, spinning really fast, and you have to go super slow.

[rapid geode]

mcd cutter (basically a real diamond glued to a stick haha)

different from grinding.. but... kinda the same effective result

[kindred isle]

Oh, apparently there's also laser machining.

[rapid geode]

yeah just saw that looking for some mcd videos

no youtube, silicone and silicon are NOT the same thing. yeesh
