Yeah but my experience has been pretty bad
They don't last long

[tardy badger]

I think the last one I bought was $10

I’ve had it for a while

Still works

A soldering iron runs much hotter than a glue gun.

As do 3d printer extruders.

[rapid geode]

no, censorbot. its fixed now. 46000 views, 290 upvotes. i guess its getting some love.

[pallid orbit]

I got a $10 one and it was super terrible, then I got a slightly more expensive one (gorilla glue) and it lasted me through a project with 90 lights I encased in hot glue

[dusty citrus]

I mean they can be managed

[pallid orbit]

the glue quality for the sticks it came with had better flow and took longer to solidify, which gave me a lot more control

[glad ruin]

Do you want a hot glue gun, or a project?

[pallid orbit]

would still prefer having a cordless one though, as the weight and short-ish length of the cord is usually a problem

[dusty citrus]

First option
As always I waste time before even concluding a project

[glad ruin]

Then just buy another.

[dusty citrus]

You're not that wrong
Thanks

[patent hemlock]

got an $8 USD one from a local art-store chain (low heat) that's working pretty well

[glad ruin]

I believe I got mine from BiMart.

But I really don't use hot glue that often. Super glue or gorilla glue are usually preferable.

I am trying to figure out if the Feather 32u4 Proto has the battery sense pin connected to one of the timers directly

The power management page says this

it seems that A/D9 is being used for the battery voltage

the library i am using uses D9 for output

so did adafruit really connect the battery measurement circuit to one of the timers?

[late fulcrum]

It is the same pin, due to the large number of functions and limited number of pins, the 32U4 chip has many pins with multiple functions. If you don't need the battery sensing functionality, it will work fine. If you do need the battery sensing functionality, you have a few options. You could make another battery voltage divider (it's just two 100kΩ resistors) and connect it to an unused analog pin. You could perhaps use a different timer, by telling the library to do so, modifying the library, or using a different library.

[dense mirage]

I need the battery sense functionality but I think I'll need to cut traces or desolder stuff to make the board function

Is a feather 32u4 effectively equivalent to a pro micro? Like, "D9" on both boards is the same pin on the mcu?

[late fulcrum]

No, you don't need to cut any traces, the battery monitor is a high impedance circuit, so the digital output won't be bothered by its presence.

On the Feather 32U4, D9 is connected to the MCU's pin 29, which is PB5 / OC1A / ADC12 / OC4B. Apparently the board definition file makes D9 also appear as A9. I'm not entirely sure which Pro Micro you're referring to, so referencing SparkFun's board (DEV-12640), They also connect D9 to pin 29, but apparently the board definition file for that board makes it appear as A8 (and there's no battery circuitry on that board).

In either case, you could add a second battery monitor made of a couple of resistors and connected to an analog input.

[dense mirage]

its being used for audio output

so it REALLY matters

[dense mirage]

yep i can do this, super easy.

thank you for the help :)

[past topaz]

sorry in advance because this question probably gets asked like 20 times a day, but about how often do the ESP-32 Pico QT Py's go back in stock/is there a rough estimate on when they'll be back in stock? just figuring out parts for a competition at the end of december and trying to figure out what the chances are i can get one by then or if i should just design for something else and not sure if it's a "they're back in stock every few weeks just check your email regularly" situation or a "they've been sold out for months" situation

[dapper hatch]

Hi all. 🙂 Been some time since I was on discord on the account of life and moving. 🙂 Excited to get back into projects and making stuff. Now my new office is taking shape.

It's a nice worm feeling when you start to get your old network kit back up and running and things spring back to life. 🙂

[late fulcrum]

Heh, I fired up a board I'd used a while back but it can't write to its SD card any more. Debugging time...

[thick wind]

DISCLAIMER: not affiliated with Adafruit, this is not an official statement of any kind.

From my experience, there isn’t always a set pattern on when they restock, as most of their limiting factors has to do with component shortages. That being said, the esp32 should have a fairly stable supply, so I’m not entirely sure what that would be waiting on. DigiKey’s estimate is around the end of December, if that’s any help…

What are your requirements? Are you adapting an existing design or looking for something to perform a specific task?

[dapper hatch]

Debugging time == fun time 🙂

[pallid orbit]

Halloween also just happened and I imagine a lot of parts needed for costumes/props ripped through existing stock

I'm recovering from running a charity LAN event's VR section all weekend and doing teardown as well, while going directly back to work this week. Hoping to start poking at my stereopi hardware this weekend

Also got to test out my RGB hair I made during one evening that we had a DJ at the event, it can last hang-banging surprisingly 🤣

[lethal fulcrum]

Does anyone know of any video tutorials for beginners on getting Adafruit matix boards working with code. I am pretty new to all this, i have some Python knowledge. Just want to know the ropes of everything. Is it only Adafruit libaries that will work on this or can I use any Python one?

[thick wind]

That depends on the hardware used to drive the matrix itself. The matrix hat on a raspberry pi might have some direct Python application, but any of the microcontroller boards like the matrix portal will require circuitpython or Arduino, which will likely work best with adafruit libraries.

Which board(s) were you interested in?

[lethal fulcrum]

I have a MatrixPortal M4 so i am guessing circuitpython is needed.

[thick wind]

Recommended, not required. Though for someone with python experience it’ll be easier than the alternatives by far.

Not all Python packages or libraries are available for circuitpython, but most of the fundamental syntax and bases are designed to be interchangeable.

Best place to start would probably be https://learn.adafruit.com/adafruit-matrixportal-m4/overview for initial setup, and https://learn.adafruit.com/adabox016 for a bunch of example projects.

[lethal fulcrum]

Great thank you for that

[lethal fulcrum]

Thanks, I have a project working. Its just working out what libraries can only be used

[fair summit]

[haughty solstice]

What editor do you use that doesn't catch that

Also else is interesting after for because it runs if the loop wasn't broken from

And try/else runs if there was no exception which is also interesting

I guess they're niche features but I'm sure there's some use for it

[glad ruin]

They do have uses.

[tardy badger]

Delicious

[glad ruin]

That's the point... the editor is literally incapable of catching it in Python. No editor is capable of comprehending your intent, regardless of how 'smart' it claims to be.

[glad ruin]

Oh, it's actually more complicated. It runs immediately after the StopIteration exception is caught (for loops in Python always operate on iterators, and iterators end by raising an exception). This means the code runs at the end of the loop regardless.

[late fulcrum]

I know that feel (curing base cement, 20 minutes at 150°C)

[tardy badger]

New CRT project?

[haughty solstice]

No but it can generally detect when code you wrote would raise a syntax error

[haughty solstice]

Huh, that's interesting. I don't think that exception is thrown though when it's broken from

[glad ruin]

Correct

But if the iterator ends (or is empty) the else clause is executed.

That was from a couple of years back, when I decided to amused myself during the pandemic by restoring the pile of broken oscilloscopes I seem to have accumulated. That one, the base had come off the CRT. I wasn't going to buy a new CRT for it, so I figured I'd try rebasing the CRT. I had never tried it before, but there was nothing to lose so I gave it a go, and it was a success.

I've been caught in that situation before, put it in bootloader mode, erase flash, reflash with new version, and hope that fixes it. If not then you're probably looking at a bug report.

it probably would; definitely worth trying. You can adjust the size of the target on the back side if needed.

[autumn badger]

Hi guys, I'm currently working on a project involving a two-wheeled mobile robot. I'm utilizing UWB for positioning, Rplidar for collision avoidance, and motors with a motor driver for the robot's movement.

At this point, I've successfully implemented the functionality to move from my current position (start) to the target position (end) using the Euclidean formula with only the integration of motors and UWB. Although I haven't reached the phase of path planning yet, I've just managed to do a simple computation of linear distance during linear movement.

So, my motor control is intended to be controlled by UWB data and Rplidar. However, when attempting to incorporate Rplidar, an error related to "Incorrect descriptor starting bytes or Wrong body size" is displayed.

I suspect that the processing might be too slow when placing Rplidar data in the main_visualization function, or there might be an issue with the code structure, such as an incorrect format. I've already attempted placing main_visualization() inside the get_data from_LIDAR(), but the problem persists.

Below is a snippet of my code, and I would greatly appreciate any suggestions or ideas on how to resolve this issue. Thank you.

I tell ya, this housing market is crazy. To be able to afford a place like the one I’m leasing would just be so expensive 🥲

Gonna have to downsize my electronics to be able to fit it in a place I can afford

[olive dome]

even with the crazy high rate....

[tardy badger]

To have a decent DTI I can only afford something less than $350k and that’s a 1200sqft condo

So no basement work space for my electronics hobby.

But you gotta start somewhere with home ownership I guess

[olive dome]

But the interest rate though

[tardy badger]

$350k or less with the current rate

Builder is offering a 3% concession on the value of the home which can be used to buy down the interest rate

So I could probably buy it down to mid 6%

Mid 6% rate with a first time homebuyer program, I’d be looking at a $2700 monthly

That is including PMI

[olive dome]

Any attachment for the first time homebuyer program if you sell it later?

[tardy badger]

Only that I have to occupy the residence for at least 5 years

Not a huge ask considering to go up to a town home or a single family home, I’d need to have enough equity to make the monthly payment reasonable for my area

If I sell the place before 5 years, I pay some prorated amount back to the program

[umbral phoenix]

what's the current down needed to skip PMI? if you do PMI, make sure there's a clause where you can cancel it when equity is X%

[tardy badger]

20% to avoid PMI, it auto cancels at 78% loan to home value ratio

[umbral phoenix]

envisions big spreadhseet with varying future dates of switching from lease to mortgage and resulting downpayment, tax/PMI/other ownership costs, expected interest rates,...

(and NPV thereof)

[tardy badger]

Yeah, it’s a headache for sure

    wifi_config_t wifi_config = {

            .ssid_len = 0,
            .channel = channel,
            .authmode = WIFI_AUTH_WPA_WPA2_PSK,
            .max_connection = 4,
        },
    };
    strncpy((char*)wifi_config.ap.ssid, ssid, sizeof(wifi_config.ap.ssid));
    strncpy((char*)wifi_config.ap.password, password, sizeof(wifi_config.ap.password));
    ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_AP));
    ESP_ERROR_CHECK(esp_wifi_set_config(WIFI_IF_AP, &wifi_config));
    ESP_ERROR_CHECK(esp_wifi_start());
    Debug("started ap");
  }```

Debug(x) is a macro i setup that serial prints but then i can just turn off the debug flag and it will put whitespace there instead so it's not in the final compile if i dont want it to be

yeah. although, i think those always have some demand

[tardy badger]

I sold my Impreza for $26,500 which was nearly what I paid for it new lol

[rapid geode]

ha

nice

i guess all that dealer upcharing is grinding to a halt now

[late fulcrum]

I found a Bentley with 35k miles for $15k. That's like 96% off the new price. But while a turbochared 6 litre engine would be fun, the gas bill wouldn't...

[tardy badger]

I kind of feel like Bentley cars are a bit ugly and generic looking these days

[rapid geode]

the bently uh... gt? the swoopy ones have really crashed hard.

[tardy badger]

Sure, you get better overall build quality

But they just don’t look that nice anymore

[rapid geode]

boxsters had suddenly becoems worth more than scrap in the height of last year

well see if that stays

[late fulcrum]

Aventador. The Flying Spurs are fairly affordable too. They're also sold with a Rolls Royce badge, but those don't drop in value as fast as the Bentley marque.

[rapid geode]

aventador is a million dollar lambourghini

im talking about the continental gt

[late fulcrum]

Oops, misrembered. It's an Arnage

[rapid geode]

arnage, ah, yeah that suuuper old pre vw. i mean new

(ish)

[tardy badger]

Personally, if I am going to spend millions on a car, I’m definitely buying koenigsegg

[rapid geode]

ha

for 1m i would make my own.

[late fulcrum]

I prefer spending $15k on a $330k car 🙂

[tardy badger]

Same haha

For now, it’s just base model Subarus for me

[late fulcrum]

I'm not impressed with the engineering in subarus, so I ignore them.

[rapid geode]

i always like to see what you can get for $200 (well, more like $800-1000cdn now)

used to be tons of porsche 914s for $500

now 20k

[late fulcrum]

I'm not impressed with porsches either.

[tardy badger]

I’ve never had issues with Subarus personally

[late fulcrum]

My dad had a Porsche 914. I think he sold it for $800.

[tardy badger]

Outside of things that were caused by my own financial situation like going 10k between oil changes because I could t afford them at the time

[late fulcrum]

And that was after he had an argument with a Buick...

[tardy badger]

Blew a head gasket at 176k miles

[rapid geode]

i could have gotten a 912 with no engine for 3k. i told the guy he was an idiot

hehe

oops

poor 914

[late fulcrum]

Currently on the hunt for an inexpensive Chevy Volt or Volvo C30.

[tardy badger]

But now I can afford my every 6k miles oil changes and tire rotations which run $100 🥲

[rapid geode]

i saw a guy in a bmw m5 drive over a subaru

not sure how he managed. he then tried to gun it and flee the scene but his drive shaft was broken

sucker

[tardy badger]

Lol

As for used cars these days, I have little faith in their reliability

[rapid geode]

ok, i think my keycaps go on sale friday. eek! gotta sand and oil some, and print the paking cards (finally done with the process and design of that).

[tardy badger]

Mostly because a lot of people these days can’t afford the standard maintenance on the vehicles they own

[late fulcrum]

For used cars, I tend to go for the high reliability models (generally fleet duty vehicles)

[tardy badger]

So you never know for certain what the maintenance history is. Yeah fleet vehicles you can basically guarantee they had regular maintenance

[rapid geode]

i hear tesla is reliable with good service... cough

[late fulcrum]

Not interested in Tesla, other than as parts mules.

[tardy badger]

There was a time where I was excited about the prospect of buying a Tesla

[rapid geode]

vw is horrible for service, but normally the car\ last a while

audi is really bad

[tardy badger]

VW is great at fudging emissions

[late fulcrum]

If I were going to buy an EV, I'd be looking at PoleStar (for the high end) or Hyundai (if they fix their brake light bug)

[rapid geode]

the polestar roadster looks neat. but 200k. oof

(200k cdn that is)

[late fulcrum]

There were some great deals to be had on the DieselGate VWs when they eventually re-sold the ones they had brought up to spec.

[tardy badger]

I wouldn’t mind a rivian if they could fix their issues with the cars locking up randomly

[rapid geode]

diesel got so expensive here that it kinda didnt make sense to buy them

not sure how it is now. the gas prices have been like a boucy ball

[late fulcrum]

I'd also consider Lucid for an EV, but those are also spendy. I'm keeping an eye on the electric Mustang too, it has some nice engineering.

[tardy badger]

Gas here is finally under $3.50/gal

I think it’s $3.27/gal down the road

[rapid geode]

1.40 a litre here. thats "middle" i guess. got up to 2.25 for a while

under $1 is more "normal'

[late fulcrum]

Is that €1.40 a litre?

[tardy badger]

I’m glad I don’t pay those prices

[rapid geode]

or, used to be normal anywya

1.40 cdn

$3.80usd /gal

[late fulcrum]

I'm still driving the big heavy V8 powered fleet duty car I bought cheap in 2008. Amusingly, it gets better gas mileage than smaller V6 powered cars.

[tardy badger]

My Subaru gets great mileage

~30mpg on average

If it’s just me driving I can get it closer to 34mpg

I can drive just about 2 weeks to and from work on a full tank

[rapid geode]

my vw rabbit diesel got about 55-60mpg

[tardy badger]

Rabbits were really good on mileage

Many small diesels were/are

[rapid geode]

couldnt go up any hills though

haha

[tardy badger]

Lol

I had a 1982 Mercedes Benz 300 turbo diesel

That thing could move

[rapid geode]

yeah. they ahd more than 46hp

hehe

[tardy badger]

The body and interior were falling apart

But the engine was still going strong

[rapid geode]

those got really valuably for the vegie people a few years ago

[tardy badger]

Cast iron inline 5

Yeah, I see a lot of veggie oil 300D running around

Hilariously I see many replace the ‘D’ with a ‘V’

[rapid geode]

im not sure what the legalities of it is. cause technically its not an emmissions tested system

not even grandfathered in due to age

anyhow

[tardy badger]

Yeah, it’s a weird grey area

[rapid geode]

alright, next thing to do today is make a vacuum fixture to hold my paper so it can be cut out

WE ARE LIVE! ASK AN ENGINEER! https://youtu.be/WWWODi_zy7g

[knotty canyon]

Is there a way to have my 2FA somehow "reset?" I have not been able to purchase anything 'cause I cannot get it working. I'm sure i'm doing something wrong, but I got a new iphone and the Auth apps do not seem to recognize any 2FA setup I previously had.

Any ideas would be greatly appreciated. 🙂

[hard estuary]

We can't really help with store stuff, most of us here are volunteers. I'd recommend contacting Adafruit here: https://www.adafruit.com/contact_us

[knotty canyon]

Darn. I thought that was probably the best way too. Oh well, I'll gve them a ring or send an email. 🙂

[stiff dagger]

[sick apex]

i think i might have discovered a way to load code from an SD card

before i spend days tryna figure it out can someone jus bounce my idea around for a second

so imagine you've got basic firmware on the ESP32

that has an interface

simple interface like this

class PluginLoader {
public:
    static PluginInterface* loadPlugin(const char* pluginName);
    static void unloadPlugin(PluginInterface* plugin);
};```

class PluginInterface {
public:
    virtual void setup() = 0;
    virtual void loop() = 0;
    virtual ~PluginInterface() {}
};```

then in the setup loop you have some code that constructs a plugin loader object and stores the object in a vector

in the setup function on the main firmware you run the interface's setup for each plugin

then same for the loop in the update function

[rapid geode]

um...

the real question is why hasnt it blown

[whole jacinth]

it seems to be a power resistor, judging by the size and the installation well above the board. they're designed to dissipate lots of heat, though usually not to incandescence. it's almost certainly dissipating above its power rating, but it's more likely to survive than a non-power resistor

[patent hemlock]

i also like the fact that it's bulging 👀

[tardy badger]

It’s cool that Pi 5 are now disappearing at the same rate Pi 4 used to

And going for $200+ on eBay

By cool, I mean really dumb..

but also have 3x Pi4 (2x2GB and 8GB) and an 8GB/32GB eMMC CM4 on the way for other stuff I'm kicking off around the house

[rapid geode]

its quite an old meme picture. i think it is actually fake.

[stoic mesa]

we really should create a "flea market" channel, for exchanging stuff we no longer need - but someone could use. I have a bunch of MCUs, e.g. RP2040 Qt Py which I bought for some project but never used.

would be happy to give them just for the price of shipping if someone has use for them

[umbral phoenix]

incandescent light bulb = LER

[rapid geode]

[umbral phoenix]

@stoic mesa that's a good idea, I recently gave a bunch of MCUs to a local makerspace

I have a tendency to buy shiny new MCUs and abandon the ones I previously had in mind for some project

i dont even know what tindie is

ahhh

thats neat. is that where people here sell they pcb designs and such?

[stoic mesa]

yes.
It is much less known than Etsy, but quite a few of people doing custom electronics design - including several people here - sell on tindie

[rapid geode]

etsy is over run by what i would call corporations vs makers. but it does still seem to be the place for keycaps. at least until my name is known and people go direct to my website

[tardy badger]

My favorite electronics trick is to ruin two I2S amps because of a small mistake on the schematic and overconfidence that I could bodge it enough to work.

Lol

[ebon dew]

I've heard chaining 2 class D amps is a bad idea but it's doable. I didn't know any better and just made it work.

I think it made CGrover die inside a little seeing that so he made a PCB just for that situation. I have yet to try it out but I'm sure it'll work great.

[tardy badger]

Lol

I’m a bit sad though because i2s audio doesn’t work right on the esp32-s3

It keeps crashing

There’s 2-3 similar bugs related to timers on the esp32-s3 on circuitpython repo already

[ebon dew]

I haven't tried audio on the ESP32 in a while because it won't do MP3 but the Pi Pico and Feather RP2040 will. So I've been using those.

[tardy badger]

Im contemplating moving the design over to an RP2040

[ebon dew]

I'm not against the WAV format but it does require an SDcard due to large file sizes especially if you intend on playing full songs.

[tardy badger]

I wanted to do it where I could load new games over Wi-Fi/Bluetooth but the reality is it just needs to work

And wireless loading isn’t a huge priority for me

It just looks so good with the module

[ebon dew]

sdcard?

[tardy badger]

It’s for my kids so SD Cards are not ideal

They would lose them in a heartbeat

[ebon dew]

Well I meant one for permanent large storage. Doesn't really need to be swapped out ever.

like the one I have in my TFT Featherwing only ever comes out if I need to take a screenshot and transfer that to PC, otherwise it stays in there permanently.

would love to see circuit python get to the point where SDcards show up as a separate drive. i'd never have to take out the sdcard for any reason. it would be a permanently large storage upgrade.

[umbral phoenix]

you could put an ESP32 on there for Airlift (SPI) wifi

should be possible to write something in CircuitPython that let's you drop files onto CIRCUITPY to be written to SD, reading from host is another matter (but ask bill88t, I think they have some *nix-like abstraction layer that allows certain commands)

[tardy badger]

There is a FTP library that bill88t made

WD40 is NOT a lubricant

[half plank]

But I looked it up and they said that the PTFE WD-40 is a good one.

[rapid geode]

when it stops, is it losing steps? is the machine just binding up?

these machiens should have grease packed in the bearings, you should never put lube anywhere else usually

if the bearings are full of crud they need to be removed and cleaned

[half plank]

But doesn’t grease attract dust

[rapid geode]

yup

thats why its INSIDE the bearings. not outside

[half plank]

Oh ok. What is a good grease

[rapid geode]

ltos to chose from, most cost more than the machine. white lithium is a decent basic one that is cheap.

but what did you do to the machine to gum it up in the first place?

[half plank]

I left the machine off half way up on each rail and left it for multiple weeks. Now it is getting stuck

Found myself making these whenever I breadboard things with lots of adjacent wires

Honestly super helpful to make visual references, but for my own WIP projects

[late fulcrum]

A related trick is I'll print sticky labels with the pin numbers/names/functions (this one is an older project so it's a bit faded but you can hopefully see the idea)

[weary fiber]

I see these in lots of project writeups, but I have no idea how they're made!

Do you get them outta a labelmaker or something?

[late fulcrum]

Yeah, I use a Dymo LabelWriter, they're great for things like that.

[urban arrow]

Curious if any of you Matrix Portal S3 owners have had one totally fail?
After months of heavy use, no CIRCUITPY drive, dbl-tap won't give me boot, program won't run of course, so I spent all day (almost) going thru all the re-flash methods, and esptool could never get thru the process.

[shy orbit]

hey guys. im trying to read an ldr on A1GP27 of a YD rp2040. i had it working on an itsybitsy but ran out of those. i cant get anything to read on the ADC pins. always returns a max value of 65535. I have a 100k ldr wired from 3.3v to A1(GP27) and a 10k resistor to gnd

i feel like im brain farting because this was really simple the other day

import time
import analogio # import analog pin functions

ldr = analogio.AnalogIn(board.GP28_A2)



while True:
    ldr_value = ldr.value
    print("Alive")
    print(ldr_value)
    time.sleep(1)

Lol

65535
Alive
65535
Alive
65535

i did a dir(board) and it seems that i should be able to use A1 or GP27 or GP27_A1 right?

>>> ```

i thought i might have fried it so i tried another one and moving to a@

A2

[solar hamlet]

what do you get when you only wire the pin to gnd?

[shy orbit]

A1 to gnd?

Its just always 65535

[shy orbit]

im measuring with my dvom and can watch the voltage change

this is so weird :\

[brittle linden]

Thinking that you can't read the internal temperature on that board either. Something in the design of these YD boards? See this issue: https://github.com/adafruit/circuitpython/issues/8403

[shy orbit]

hmmmm

what could i try? i bought a few of these boards and it seems like something simple. also theres a vref pad, should i be using that?

[weary fiber]

Just finished!

[shy orbit]

thats cool

[brittle linden]

Looking at the YP schematic, they left a few parts out of the ADC_VREF circuit. They feed the RP2040 ADC_VREF directly from the 3.3V supply via a 0 ohm resister. It should have a 200R to drop it below the supply rail. Also, the 3.3V rail is coming from a $0.06 regulator, so I wonder how clean/accurate that is. If you want to supply your own ADC_VREF, you'll need to remove the 0R first.

[shy orbit]

i dont. i just want it to work

gounding the adc pin should give me 0 and i continously get 65535

ive tried 3 seperate boards and have nothing else hooked up. im wondering if the uf2 file is broken

just trying to get an LDR to read xD everything worked fine on the itsybitsy

[brittle linden]

No, I'm pretty sure it's the YD board's design.

[shy orbit]

that the adc just doesnt work?

[brittle linden]

Could be. YGWYPF.

[shy orbit]

xD

i guess.

success!!! there was a vref pad that needed to be soldered!

[brittle linden]

So that 0R in the schematic wasn't stuffed. Could you leave a photo of where you soldered?

That will likely answer the open issue above, too.

[unkempt meadow]

I am not sure this is the right place to ask this. I have brand new out of the bag Metro ESP32-S3 with 16 MB flash. I plug it into my Windows 11 laptop via a USB-C connector. It powers up and starts flashing LEDS and running some sort of bootup code changing the colors on the NeoLED. But it is not recognized as an external storage device by Mu Editor or the Windows File Manager. My question is should it be recognized over the USB or is there some sort of configuration needed on either my PC or the board?

I am looking for suggestions on what to do next. I posted last night in the Metro forum and have not gotten an answer yet to the question.

My board is the latest version that was only released about 10 days ago.

[idle lion]

I think it comes with a Demo that is programmed in Arduino pre-loaded on it.

If you want it to appear as the storage drive CIRCUITPY you'll need to install circuitpython on it.

This page contains the instructions for loading circuitpython https://learn.adafruit.com/adafruit-metro-esp32-s3/circuitpython

[unkempt meadow]

I do want to install CircuitPy, which I did 2 years ago on a Feather M0 Express. I forget exactly what I did though.

I downloaded the *.uf2 file from that page last night, but do not know how to install it, because I don't see the device show up in the Windows 11 file manager when I plug it in

[idle lion]

The instructions are on that page I linked. Essentially it's double press the reset button with the correct rythm to get the METROBOOT drive to appear for pasting the UF2

Plug your board into your computer, using a known-good data-sync cable, directly, or via an adapter if needed.

Double-click the reset button (highlighted in red above), and you will see the RGB status LED(s) turn green (highlighted in green above). If you see red, try another port, or if you're using an adapter or hub, try without the hub, or different adapter or hub.

For this board, tap reset and wait for the LED to turn purple, and as soon as it turns purple, tap reset again. The second tap needs to happen while the LED is still purple.

If double-clicking doesn't work the first time, try again. Sometimes it can take a few tries to get the rhythm right!

[unkempt meadow]

ok, I missed the instructions after the download last night. Thank you for pointing them out

I am using a cable USB-C to USB-A to plug into my laptop. It transfers data to my recent model 2022 kindle, so I assume it works as a data cable

Yea, I definitely screwed up, not double pressing reset. I am heading to dinner now. Really appreciate your helf foamyguy#2825

help not "helf"

[urban arrow]

Yes, what Foamy said. I have a similar ESP32-S2 board, and the procedure is the same. They don't ship with CP loaded. You should see a board called "METRO..." after the double-tap reset, to drag the UF2 file onto

[unkempt meadow]

What is "CP"?

[urban arrow]

Oh, short for CircuitPython

[unkempt meadow]

oh. sorry not too quick on my part. I like CP on the old Feather M0 Express and am excited to have so much more memory on the ESP32-S3

[urban arrow]

No worries. I was a total new user just a few months back... This forum is great.

[shy orbit]

I forgot to say ty earlier. thanks a million!

[unkempt meadow]

I just want to let foamyguy and gcm2 know that I now have a CIRCUITPY directory on the new board. Thanks again. On to trying out an I2S device.

That's a "solder jumper" instead of a pad for a 0Ω resistor, but the result is the same: a solder blob makes the connection

Hmm, maybe I should have tagged @brittle linden instead

[tardy badger]

I like the account name “lord of the pies”

[pallid orbit]

unless I go directly to the etsy or main website I literally cannot find anything about your keys in search engines btw

[tardy badger]

Probably need to do some SEO

[pallid orbit]

wooden "fail keys" etsy custom keycaps on Google gives zero results, which is rare

[tardy badger]

I get the ancient red cedar keys as my second result

Searching failkeys Etsy

Also tons of photos from Reddit showing up in the search

[pallid orbit]

oh, one word

[patent hemlock]

ah -- this one produced results (on Bing) "failkeys" etsy keycaps

[rapid geode]

its only been up a day, it takes a whil;e for anything to show up

it only just started showing in etsy search results a few hours ago

if i remember from my guitar stuff, it took a while to grow organically. now if you go on etsy and put in guitar 3d, mine comes up fir (and often second and third)

i need mind to show up when somoene searches artisan and wood caps. thats the trick.

my first reddit post had some viral interest, but they werent for sale yet. the second post for actual sales went mostly unseen

ive got 3 to ship out tomorrow though. getting them into peoples hands i think will help

[tardy badger]

Absolutely

Hopefully it ends up working out

[rapid geode]

yeah. i need to recover the money i spent developing these. haha.

im always bad at selling though

the guitar stuff is not physical, so i just stuck it up and basically forgot about it. eventually (over a year) it grew on its own. although that's such a tiny amount of money.

[tardy badger]

Same, I set up a Fiverr for doing PCB design but I’ve kind of neglected to even share it anywhere

😬

[rapid geode]

ha

i did a kickstarter for my cats a long time ago. same kind of issue. everyone who found it loved it... but almost noone found it

[tardy badger]

I really could use the extra income but my current job sucks all the motivation I have

I do have a dream though of opening an anime cafe

[rapid geode]

ha

O-o

[tardy badger]

Get anime themed sandwiches and drinks

[rapid geode]

ha

take all the recipes from babish

[tardy badger]

Have a corner with tables for doing table top games

Have a anime marathon every weekend, two rooms with comfortable seating for like 10 people each, snacks, drinks, etc.. based on a monthly membership of like $150/m

Have two different anime running at any time

Then also have a small part of the shop be for like trading cards, physical copies of the manga

That’s the dream, I need to save up like $100k or so to do it

[rapid geode]

ha

100k seems low. ive designed restaurants before.

[tardy badger]

I mean just the front money, not even the business loan to finance it all

[rapid geode]

ooh

ok

hehe

[tardy badger]

What I want to do would easily be a $400k, probably closer to $1m venture to start

[rapid geode]

yeah

[tardy badger]

$400k if I do most of the work myself

I feel this too much with my current job and working on any kind of software outside of it, my brain is too fatigued to continue coding outside of work

[tardy badger]

My day job is coding, PCB design is mostly artistic work

[rapid geode]

my day job went on strike half the year. grumble. now it needs to pick back up again. (unless i become a multi hundredaire selling keycaps)

[tardy badger]

It also involves spending the day working on a project only to be told in the middle of things that the projects funding is being cut as are my hours working on it lol

[pallid orbit]

though last week I had merge conflicts with some data prefabs I had to modify, that also collided with another of my branch, and I had to redo stuff, didn't push some of it to the repo, my SSD died over the weekend, and I've spent this morning catching up on whatever my current working state actually is after fighting with git's index lock file getting stuck

[fickle aurora]

does anyone know why featherwing doublers come with standard female headers and also extra long stacking female headers? I'm having trouble imagining the stacking ones get used nearly as often so including them is a choice I'm not understanding

[fiery quarry]

If he's accepting of criticism the questions are all prepositioned for the answer he's expecting to find

[fair summit]

you can always cut off the long legs. The idea is that you might want to use the stacking headers on a Feather or FeatherWing to stack a third board on top of one of the boards on the Doubler. Or you might want to plug the doubler into a Feather or FeatherWing that is underneath the doubler. The latter two cases are rarer, but giving you a set of stacking headers gives you that option.

The tripler and the two quads just come with regular headers.

[umbral phoenix]

@fickle aurora I almost always use stacking headers (except for displays). On a doubler, I'll use stacking headers on both sides, cut off the legs on one half, and pop it in a solderless breadboard.

Hello - this may be better in help with projects but I used some flux wire and ended up melting my ribbon while trying to remove solder from it - any way to solve this or is the project compromised?

[rapid geode]

im not sure you can fix that. sometiems on a pcb you can solder further up the path, but i dont think you can here

[pastel steppe]

Ah what a shame

[pallid orbit]

I imagine someone with a lot of experience might be able to do something about that, but personally I wouldn't at all

[ebon dew]

same, encountered a similar situation the other day and my first thought was nope, beyond my skill level. this is exactly what i would have expected to happen.

[pallid orbit]

my big fear is having to move the cable for my AR glasses from my current project to my next iteration without damaging it, though I am not having to solder - it's just a lot of super thin wires for USB-C

and it's so specialized I'd have to buy another unit from the glasses I stripped down as they don't sell repair parts for it

[mental bane]

oh dude thats gg

[pastel steppe]

Lol - what a shame - follow up question, I’m pretty sure it should be totally possible but this project required a pi zero, I had to solder a 40 pin connector to it but I think I might just use it for a retro pi/mini console, that should still be possible right?

((I’m a beginner))

I can’t imagine the 40 pin should interfere with this just hooking up to like a usb controller/hdmi output

Those leads don't look like they go anywhere, you might be lucky

Really really really lucky

You need a copper solder wick to remove it from that in my opinion

Also don't use a soldering iron for that. Use a hot air station.

trhey go to vias to the other side of the board. but that is a good point. figure out what the signals are because a lot of times pins arent used or are redundant grounds

No, Pythonista the iOS app won't work for CircuitPython. You need a computer to plug the microcontroller in to, and then you add the libraries to the /lib folder on the board and edit code.py which is also on the board

super weird digital/signal issue. In some forums I found that about 6 monitor models from different brands are affected. All are 1440p except one which is 4k. Most are 27" or 32". I suspect that they all use the same IC or something for something.
Basically:
Flickering in the bottom third, or bottom right corner of the screen when the GPU outputs the image in the same resolution/refreshrate that gets displayed.

• GPU set to 2560x1440p60 (native resolution of the monitor) => flickering
• GPU set to 1920x1080p60 and monitor set to Image Ratio: 1:1 (so the image get's displayed in a small box in the center) => flickering
• GPU set to 1920x1080p60 and monitor set to stretch the image to fill the screen => no flickering.
• GPU set to 2560x1441p60 or 2560x1440p61 or similar weird resolutions that are just slightly off => no flickering.

3. Add a Lego set to reward yourself for being so generous this holiday season

I've been collecting lego minifigures in the past year

[tardy badger]

So Lowe’s home improvement store is doing this thing today where you enter your email and get a chance at $10k plus the ability to get a part of $200k in gift cards. The prize site is unreachable right now. This is likely because Lowe’s made themselves an easy target by not requiring 2-factor authentication 💀

and then still sell it for 80% of what i paid later

[late fulcrum]

I suppose it depends on how much you intend to use it. I'd probably just need a few days every ten years or so.

[urban arrow]

OK so it's ugly. It works. I had the shield on a Metro M4 that I repurposed, and a Feather RP2040 without a display.
So my hare brained idea was to wire up the shield to the Feather using a doubler.
Probably gonna make a more "permanent" arrangement using a Tripler and wire in a Airlift FeatherWing. Don't know. It's fun to switch things around sometimes w/o always having to buy more stuff. I do enough of that already 😀

HI all, i seem to have a problem which i am lost on,
I am trying to work out what's wrong, if anybody can help me on this it would be great!

The problem is, my wifi doesn't work on my esp32 s3, feather s3 by unexpected maker, with Arduino IDE or PlatformIO using the IDF or Arduino framework.

But the wifi works fine when i edit the code file on the usb memory, ( using circuit python)

the board comes preshipped with circuit python,

I am stuck on what's wrong.

I see that the bootloader is a 2nd bootloader loaded on top of the rom called UF2, which is adafruits branch of micro python.

So i wonder if there is an issue with the UF2 running IDF code? or there is something else missing that should be done,

I heave read up on the UF2, its use, but i cannot get wifi to work on anything apart from circuit python.

Any ideas please?

some also allow for AirPlay or other streaming sources to be used

[jagged citrus]

Lil bro got lucky

It is indeed a network player

Receiver

Thingamajig

Its an onkyo TX-8050

NAAAAAAAH

https://youtu.be/GzDSlP_63Kw?si=A-cAi0JDKc1TFaZC

The device also has WiFi connectivity (if you connect a wifi dongle)

[umbral phoenix]

(internet on consumer devices also exists to phone home with tracking data)

[rapid geode]

and to send your pictures to elon

[lusty fossil]

My christmakkuh present to myself came 3 days early.

[spice moss]

nice

[glad ruin]

I was going to suggest that it could be this, but it appears to be consumer-oriented.

[lusty fossil]

Some day audio over ethernet will be used for hacking and we'll all learn about AoE Attacks.

[glad ruin]

In most cases it appears that AoE is implemented at layer 2, i.e. the same layer as the IP stack.

[patent hemlock]

well, folks, i just got finished watching the Dr Who special -- if you're a Whovian and been disappointed of late, i do believe you will be much happier

[pallid orbit]

I stopped halfway through capaldi and heard it got worse, so I hadn't bothered

[patent hemlock]

capaldi finished ok (his last special because the last season was meh) and I think jodie whitaker was hampered by awful scripts and writing, but this is Russell T. Davies at his best Dr Who

[rapid geode]

dr what?

[dusty citrus]

Does anyone have any suggestions about a cheap lightwave long range transceivers? It will be used in a drone

[late fulcrum]

Pulsed LED? Xenon strobe (that one has been used from orbit)

[rapid geode]

flash headlights. hehe. I never really think of optical singlas as just a flashing light. I guess cause its usually not visible light

[patent hemlock]

i can't think of anything that would be cheap or light enough -- and i would think line of sight would be awfully restrictive for a drone (just my opinion)

[weary fiber]

Had an idea this mornin, thought I'd share here for input

not entirely sure if this'd really be useful

[honest jolt]

make it emulate a USB keyboard so then you can press a button to type it out?

[late fulcrum]

Add an ATECC board for a HWRNG password generator? Add a photosensor to copy passwords from a screen using a program to flash a square on the screen to transmit the data (like the Electric Imp does)?

Use a touch screen instead of a tiny keyboard for an even more compact device (could use something like Graffiti to capture input)?

[weary fiber]

Both of those are great!

also looked up ATECC chips-- I find it so cool that so many chips are like this nowadays lmao

like as few pins as possible to get the job done

purely because more complex communication protocols are basically free (design wise) now

[dusty citrus]

Something that more or less works out of the box? Like a module or the kind

[late fulcrum]

Well, that depends... You'll have to parameterize what "cheap" means, what "longrange" means, how flexible your definition of "lightwave" is, what dropout rate you'll tolerate, your weight and power budget, bandwidth requirements, whether it has to work in full sun, etc. You might be able to use IRDA transceivers, or you might not. You might be able to use something like a TV-B-Gone circuit and ordinary IR receivers, or you might not. You might be able to use a low power laser diode, or you might not. You might be able to use some LEDs and a tracking station, or you might not.

[dusty citrus]

You're not wrong... But yet I can't tell precisely due to low knowledge about RFS, and the project stage. I was thinking anything about ≤100€, and being able to stream video 720/1080p; can't I just put a random gsm module like the gsm7000?

[late fulcrum]

GSM is hardly "lightwave". It also eats a fair amount of power. But modern implementations might have enough bandwidth for video. However, it isn't point to point (normally), so you'd stream data to a tower, which would then forward it somewhere for consumption. However, it can cover plenty of range.

I don't know a lot about the newer technologies like Cat-M, Cat-NB, and EGPRS, which may provide additional options.

[olive dome]

Remember back then when the 3G first shows up, it is marketed as video calling services, I really doubt you can use 2G for video streaming

Just go with LTE, is is now almost as cheap as GSM modules back when GSM module is only the reasonable options compare to 3G modules

[rapid geode]

lte is great if you live under a tower.

:x

[umbral phoenix]

@urban arrow if yyou look at the back view of the AirLift shield, looks like you can cut the trace to 10 and make it something else https://www.adafruit.com/product/4285

[urban arrow]

Thanks - you mean cut trace and jumper a wire soldered over to another pin pad? Never done this.

[umbral phoenix]

@urban arrow yes, exactly

[prime sand]

Hi look at my project

[sturdy patrol]

That's really something, whatcha using it for?

[plain brook]

Hi All, what would be the best channel to talk about uf2 bootloader here.

[late fulcrum]

I suppose it depends somewhat on what aspect you want to talk about. Are you implementing one or using one? I'd guess #help-with-projects would cover most of them?

[rapid geode]

is that an entirely printed robot? neat

[tranquil swallow]

macbook has been so problematic, hopefully intel's next gen mobile cpus are good

[late fulcrum]

Problematic how? I don't expect intel to abandon their long-obsolete X86 anytime soon

[brittle linden]

Maybe they haven't abandoned it, but at the micro-architectural level they certainly don't use it. They've kept the ISA, but they rewrite dynamically to a saner set of micro-ops. It's not cheap as can be plainly seen by the power consumption vs. Apple silicon for similar performance.

[dusty citrus]

Buildroot what kind of packages supports? Trying to use some kind of secure-delete but nothing works. There's shred, but it doesn't clean the free space to my knowledge?

[glad ruin]

Intel's microarchitectures are a non-deterministic mess because of this. The lengths they've gone through to 'optimize' x86 are insane.

[brittle linden]

Legacy debt deluxe.

[glad ruin]

And when it breaks... it really breaks. Meltdown, Spectre, and more recently the issue with instruction prefixes.

[half plank]

Is there a picture that graph a scl and sda i2c message on an oscilloscope from a max30102, provides labeling of the different parts, and also provides binary for it?

[burnt tendon]

Imagine a world where, instead of Intel pushing the x86 to infinite lengths, instead we had the 6502 pushed to infinite lengths past the 65816.

[late fulcrum]

There are some good labelled diagrams of I2C transactions on the web, but I don't know of any for that particular chip

[glad ruin]

Honestly that would have almost been better. The instruction encoding was definitely far simpler than 8086.

[late fulcrum]

Then again, imagine where we'd pushed the 1802 forward. Register rich, load and store architecture, we'd have gone the rest of the way to RISC much quicker.

[glad ruin]

1802?

Oh I like that design.

For others wondering:
https://en.wikipedia.org/wiki/RCA_1802?wprov=sfla1

It's also one of the cleanest 8-bit architectures I've ever seen, aside from AVR (which came out in the '90s).

Just one question: what were they waiting for? The thing took 18-24 clock cycles per instruction... were they doing everything bit-sequential?

[brittle linden]

Not necessarily. Sometimes you'd need to wait multiple cycles for a result to form through deeply nested logic. Not to mention carry propagation in the ALU when you couldn't afford the space for CLAs.

[late fulcrum]

It'd make a nice Feather...

[brittle linden]

Also, the early 8-bit CPUs were not pipelined (unlike the the AVR which is), so a complete instruction cycle took an i-fetch, operand fetch(s), operate, stores(s), and was rarely if ever overlapped. RAM accesses usually involved multiple cycles of wait time. Register files almost never had multiple ports.

[plain brook]

I am thinking to modify the current one which I am using which is uf2

So the current uf2 bootloader goes into bootloader with double reset click, I was wondering if we can add a timeout so it can exit bootloader a certain time

I am using samd21 for weather stations and sometimes esd make it kick into the bootloader mode which I then have to manually reset

Kinda pain since after adding some TVS and surge arresters there is stil a chance ESD would go through the coax cable

[astral portal]

use a ribbon cable and a seperate board to seperate the feather from the computer

[wet patio]

Would anyone by chance know what type of oil/lubricant for the motors on these household fans? I use oil for a car and it only works temporarily on the motors

[late fulcrum]

It's not that picky, my usual choices are "3-in-one" oil or sewing machine oil. However sometimes it's necessary to disassemble the motor and clean the bearing surfaces (not that difficult, you don't need much more than a screwdriver and some paper towels).

[rapid geode]

i have some intel 8086's and 8088's with nec coprocessors.

no idea what they are useful for besides ornaments 😛

[late fulcrum]

They have the useful detail of being practically 100% efficient as heaters

[rapid geode]

yeah but only like 2 watts

easier to put some renders on my amd 7950x

hehe

cause it is fricken cold and snowy today :/

[wet patio]

Thanks, I'll try the 3 in 1 and give that a go and 🫡
