[lavish patrol]

Here are some colors for you: https://en.wikipedia.org/wiki/Web_colors

[cinder wind]

omg that keycap is so awesome. now to get 101 of them

[viral sail]

You should add a mini TFT to that keycap.

[lavish patrol]

Like the Lebedev keyboard.

CircuitPython keyboard question - is there a way to prevent it from mounting as a drive when used as a keyboard? And then get it to mount another way when you need to?

Field repair of the camera hanger, all in a day's work.

[haughty quiver]

ooh I got it to re-engage the friction lock, all good now

@idle spindle that's a neat looking keyboard. Do you know if it fits any of the standard cases like GH60?

oh whoops, sorry that was @warm pulsar who posted it

[idle spindle]

@haughty quiver lol its ok

[warm pulsar]

Yes - it fits in the standard plastic shell for GH60 - and even have my work one in a low profile aluminum case

[haughty quiver]

oooh snazzy!

for anyone following along, this is @warm pulsar 's keyboard, or at least one of them https://www.tindie.com/products/jpconstantineau/pykey60-rgb-keyboard-pcb-with-a-rp2040/

[warm pulsar]

The "Black Metallic Look" GH60 shell on Adafruit's store isn't GH60 compliant but the other ones are.

[haughty quiver]

uh oh, what's non-compliant about that one?

[idle spindle]

@haughty quiver if you do get a chance take a look at that doc please i cant figure it out because im a newbie at coding. i just flat out dont get it lol thanks again.

[warm pulsar]

The standoffs are meant for being screwed at the switch plate and not to the PCB itself.

Standard GH60 screws the PCB not the switch plate

this means that it's a few mm too long for the USB connector to line up.

[haughty quiver]

oh no

[cloud arrow]

those keys were so big, they look like Walter Mathau's two front teeth in dennis the menace... GLORIOUS!!!

[haughty quiver]

@idle spindle I don't have a keyboard w RGB LEDs to try it on, but looking at that doc it seems you should add the enable info https://github.com/KMKfw/kmk_firmware/blob/master/docs/rgb.md#enabling-the-extension at the top of your code.py and then change the number of num_pixels= to whatever number you have. To have it actually do something, you give it additional instructions such as shown in the example at the bottom of the page

[grand tusk]

When was the first "Desktop of Lady Ada" show?

[clear matrix]

Good question. As in the absolute first?

I figured it would be obvious on YouTube but it's not. I can ask though.

[haughty quiver]

The year was 1955. Disneyland had just opened in California, the polio vaccine had been declared safe, and minimum wage was $1 per hour.

[grand tusk]

Heady days indeed.

[clear matrix]

Found it, I think. "Streamed live on Sep 6, 2015"

At least that's the oldest in the playlist.

[grand tusk]

I just watched one from 2016, just after the Pi3 release.

It's fun to see how things evolve.

It nice that you now have a big variety of potentiometers. I have a friend who is getting started with analog audio circuits and this is going to make things easier for her.

Q: when debugging with print statements, is there a way to include the statement line number in the print string?

[grand tusk]

share screen?

[inner spade]

Thanks!

[ionic garnet]

u can include the method name but not the line num I think

[nova totem]

I think I tried it with 2 wav files when I did it for RP2040

[smoky island]

I was able to get multiple wav source files playing at once with this project: https://hackaday.io/project/169688-adventures-in-bleep-bloops-with-circuitpython My wavs are short tones generated for different notes, not a larger more complex song, not sure if that makes a difference.

[warm pulsar]

On the arduino side, it' s not in the HID - it's on the connection object

[eager matrix]

"`import sys

def LINE():
return sys._getframe(1).f_lineno

print('This is line', LINE())`"

this is one way to print line numbers in python.

[ionic garnet]

nice

[inner spade]

Excellent! I’ll give it a try. Thanks!

[warm pulsar]

MAC address is what I do to manage profiles in BlueMicro_BLE (Arduino)

[odd zodiac]

Hello all!

[eager matrix]

You can also print the filename this way
"`import os

print('getcwd: ', os.getcwd())
print('file: ', file)
`"

[dim wigeon]

It’s interesting that in the Python docs, other sys functions beginning with “_” (like sys._current _frames()) carry the warning “this function should be used for internal and specialized purposes only”, but sys._getframe() does not.

[eager matrix]

Good point. I suppose debug prints can be considered internal and specialized. Either way is fine since it works for debugging.

[ionic garnet]

I agree debug prints are a safe use for internal and specialized functionality

[celest vessel]

prefixing function names with _ is an old practice from C and Unix.
The functions were usually system functions that were NOT guaranteed to be available in future releases, or that might change in future releases.

[dim wigeon]

That’s what I was thinking, that sys._getframe() is not guaranteed not to break/disappear/change its semantics later. But that may not be a huge concern here.

[eager matrix]

I'm going to look at Bluetooth MIDI the ESP32 soon.

[upper sandal]

on board editor for CP ? pyBasic ? 😉

[ionic garnet]

It's also commonly used to denote functions meant for internal use versus those meant to be exposed. It's a stylistic way to control scoping

^^^ _ and __ prefixes

[upper sandal]

get the nano editor running on the pico

or the other way around, I don't know any more

[ionic garnet]

Ha!

drives me crazy that nano is pico and pico is nano

[smoky island]

Kmatch made a basic editor that runs in CircuitPython for this project: https://hackaday.io/project/171269-cyberdck-a-circuitpython-anatidae There is also keyboard support by using a seperate microcontroller as an interface for it.

[fair fulcrum]

would kinda be funny to use a CAN feattherwing to network a split keyboard.

[upper sandal]

there is demand for I2C and SPI peripheral every now and then

[grand tusk]

I think SPI peripheral is possible on the RP2040 using PIO.

[warm pulsar]

SPI Peripheral would be useful to simulate a display to test your code. Other than that - not sure

[upper sandal]

yeah, I saw somebody mention SPI, but it's mostly people asking about I2C for communication between two Circuitpython devices

[eager matrix]

I wonder if some company will design architectures for RISV and license those. The API is opensource but that doesn't preclude licensing a design for it. Someone would become the ARM of the RISCV world. Intel is well position for this and they definitely need a lower power RISC option.

[warm pulsar]

I2C is really the one that most would ask for as it doesn't need so many wires...

[celest vessel]

The RP2040 has a SPI peripheral, so there shouldn't be any need to use PIO to implement one, it's already there (like UART), just on specific pins. The only advantage you'd get from PIO would be to use different pins or as an additional SPI peripheral.

[upper sandal]

yeah but that requires C code, if you can do it with pio and pure python, I would be curious to see that

(don't know about it being practical)

[celest vessel]

I2C is much more complicated to implement since SDA is bi-directional, SPI is easier since MISO and MOSI are both unidirectional. (and there is no ACK, so the handshaking is much easier in SPI)

[fair fulcrum]

not directly circuit python related. You ever see those lego sites that you can catalogue all of your legos and then they will tell you what things you can build with what you have. that would be kinda neat for adafruit learn system.

[balmy tinsel]

I did not know that was a thing but dang that sounds very cool

[warm pulsar]

That would be neat... What can I build with all that I bought.

[open surge]

if it showed all the learn guides for what we've bought, it could be a long list for some of us. ... 🙂

[celest vessel]

I think a future collaboration between Adafruit and Lego would be pretty awesome. (and Lego is very specific in that the correct term is Lego bricks, and not LEGOs). 🙂

[eager matrix]

Python threading is pretty weak. It really should be able to handle multiple cores and do real multitasking. I've always wondered why this hasn't happened.

This is an issue with mainline python.

[sinful meadow]

I think it's mostly about the gc

[ionic garnet]

I support your thinking on the multi-core stuff Scott. I would use it, but if I had to I could use C++ or micropython

[eager matrix]

Once thing move forward more with multicore Arm chips there will be more demand for this.

[ionic garnet]

yeah

[balmy tinsel]

Agreed would rather see a new processor supported than multi-core processing

[ionic garnet]

sorry folks. Have to go get our Thai food dinner. See you next time. Thanks @rapid hornet

[celest vessel]

most developers mess up multi-threaded code, too much of it is non-intuitive and really easy to get wrong, creating some really difficult and obscure issues to debug.

[eager matrix]

I just use C/C++ and an RTOS if I need it but it would be nice for python to have it.

I'll think about it. My list of projects is getting kind of long.

[upper sandal]

for C python there are attempts to do better multi-threaded, but among issues, I read that the C python core team said that they would reject any multithreading solution that causes any reduction in single-threaded performance

[celest vessel]

I'd love to see it, but it could be a support nightmare, LOL.

[grand tusk]

Just add another feather?

[eager matrix]

Oh man, I'm all about digital audio. Maybe this just move up a bit on my list. Also, I'm working on an audio in/out featherwing so this make a lot of sense for me to look into.

[sinful meadow]

in javascript other core stuff is sort of in a separate vm and passes messages with main

[dim wigeon]

I’ll try to do a CircuitPython2022 post this weekend. But after a pandemic related layoff and a serious health crisis last year I’m trying to get back to CircuitPython and making in 2022. And one thing I’m planning to start doing in the next month or so is make/CPY streaming on Twitch. I’ll keep the community posted.

[modern night]

a ulab extension to do number crunching would be neat.. though yeah implementing it would be a support nightmare

[eager matrix]

Pauls audio library is great.

[fair fulcrum]

took me a second to remember: https://rebrickable.com/

[open surge]

[grand tusk]

Yeah, await-able networking would be great.

[eager matrix]

Does Wippersnapper use mqtt?

[grim ginkgo]

httpx is another one... There are a couple async http libraries

[nova totem]

when I never have to type is31fl3741 again I'll be happy 🙂

[smoky island]

You need a giant hotkey button to type it! 😄

[nova totem]

ha! It's muscle memory now

[grim ginkgo]

That's a great excuse to get an Adafruit Key Boar

[modern night]

I need to get better about writing up my at home projects..

[nova totem]

Looks like wippersnapper uses MQTT (just happened to have the source open so looked)

[warm pulsar]

muscle memory: It's a pain when for work you deal with NFR and for hobby you work with nRF. How many times did I mis-type one for the other...

[fair fulcrum]

gratz!

[green bison]

missing the show I planned to watch because I had to come in on my day off! Hope everyone has fun, I'll try to watch later.

[inner spade]

For STEM use, would be nice to have a standard data storage and automation protocol supported in CircuitPython.

[warm pulsar]

SSSS land! Watch out for

[celest vessel]

LOL, the great thing about standards is that there are so many to choose from. 😉

[inner spade]

Scientific instrument control.

Like IEEE 488

[timid plover]

you mean CP controlling IEEE-488 ( GPIB? )

[timid plover]

or being a IEEE-488 peripheral

[clever summit]

🇸🇪 👋

[inner spade]

-ish. Something with economical overhead.

[warm pulsar]

How much power does the ESP32-S3 use with BLE (no WIFI)? (assuming wifi will take a whole lot more)

[eager matrix]

@rapid hornet Get Beyond Compare. It does a nice things with git.

That looks nice tool. I'll give that a try.

[grim ginkgo]

In my experience WiFi is pretty power hungry. My esp8266 drained AA batteries as if they where Jaeger shots on spring break.

[fair fulcrum]

Lady Ada standard answer is, that you would need to test it with your code because there is too many variables. buy a https://www.adafruit.com/product/5048

[brazen quail]

Are there any examples in CP doing double buffering aka glitch free bucket logging ? Maybe via M2M ?

[eager matrix]

Nice!!

[timid plover]

speaking of power consumption - how well does the nordic power tool work with measuring other processors power usage?

[warm pulsar]

I have a PPK2 and a PPK (the original one).

[fair fulcrum]

nice =^-^=, i bought one... i havent actually set it up yet

[eager matrix]

I've not used it but Andreas Spiess uses it on his YT channel and it looks good.

[warm pulsar]

The PPK2 is really sweet. It doesn't care what you connect it to - it just measures current at the voltage you set.

[shell mason]

great tool

[warm pulsar]

It's super useful to troubleshoot why current consumption goes up/down and match it with code that's running (using the logic pins and adding pin toggling code in your code)

[celest vessel]

you could also use one of the INA breakout boards (ANA260, 219, 169, etc.)

[warm pulsar]

nrf5340: dual core. One dedicated for the radio, the other for the application.

[eager matrix]

Andrew Spiess has a vid on ESP32 low power mode that is really good - https://ytube.io/3PH2

[timid plover]

desktop?

[warm pulsar]

nrf5340: haven't seen any modules or anything use them yet.

[grand tusk]

Did that say dual M33 processors?

[warm pulsar]

(although didn't really look)

[fair fulcrum]

i dont understand why I have such an affinity for nordic chips

[warm pulsar]

I get the same questions for wireless keyboards. How big a battery... Drives me nuts too

And then they want RGB for every keys. They use lots of power...

[balmy tinsel]

How about how much does it cost to 3d print / machine / injection mold something? Their is no more info then that provided not even a rough object size

[eager matrix]

You should say "this big" and hold your up you hand up with your thumb and finger this far apart, like I just did. or just say "eleven big, it's one bigger"

[dim wigeon]

“A million dollars”? 🙂

[fair fulcrum]

digikey has a bunch of PPK2s in stock

[wind spoke]

Is it me not following closely or it's been a long time since a new product was leaked in this stream and turned sold out in less than an hour?

[celest vessel]

the nRF PPK2 is in stock @ Digikey and @ Mouser

darn, Tigerbyte beat me to sharing that!

[fair fulcrum]

🥇 =^-^=

but its not a competition lol

[modern night]

There's an art to balancing mental health and time when it comes to helping others online

[fair fulcrum]

wireless keyboards still scare me with the lack of encryption on most of them. Not that i think that anyone would sniff my keyboard packets.

[balmy tinsel]

very true. For those of us who've done this for a few years or more it's easy to forget how little any of us knew when we started out

[warm pulsar]

Answering the same question over and over again: That's why the ZMK folks created their power estimator and they only point to it now... https://zmk.dev/power-profiler

[eager matrix]

Yep. I'm going to learn a lot about this soon. The analog audio friend of mine has a mental block about looking at a schematic and building it on a breadboard so I'm going work with her and see if I can figure out a way to teach in in a way that matches her learning style.

[warm pulsar]

ZMK is a keyboard firmware build on top of Zephyr. They have been focusing on the nrf52840 but are expanding to other CPUs (because of zephyr support). My main issue with that is if you need to troubleshoot your hardware, you have nothing to work with (unlike CircuitPython or Arduino)

[grim ginkgo]

I watched this hackaday presentation of this guy in Dallas that reverse engineered the smart powermeters there. Bought loads of power meters and relay points from eBay. Listened to their signals in a Faraday cage so he could analyse them.... Wireless keyboards are like garage keyfobs, compared to that .

[smoky island]

Multiple drives - like being able to directly see and change files on the SDCard plugged in to a PyPortal would be amazing 🎉

[fair fulcrum]

that stuff is always super cool

[warm pulsar]

Live minute-to-minute power reading is the holy grail of collecting your own data.

[timid plover]

we have similar smart meters here to - been following the Dallas hacks

[fair fulcrum]

will need to check that out!

i was thinking about building a modified version of ladyada's old killowatt hack

[grim ginkgo]

https://youtu.be/T4rKaqjUXXs

[warm pulsar]

The shelly plugs are pretty good for monitoring. Got a handful here but haven't set them up (Jeff Geerling did).

Whole-house data collection from the meter coming into the house is the holy grail I was talking about...

[eager matrix]

@rapid hornet Ha, the phrase "pull-up" is going to have a different meaning in a the next year.

[simple fractal]

i have some ac current clamps on each phase at my panel. so can monitor it all. BC Hydro also allows users to buy a 3rd party device that can get realtime data for your smart meter connect residence.

[warm pulsar]

I wonder if SaskPower allows that too. However, I don't think our meter is that "Smart" We still have to go read it and enter it on their website to get real and not estimated usage.

[timid plover]

would love to read that low power pdf - if you can find the link

[rapid hornet]

https://www.st.com/resource/en/application_note/an4899-stm32-microcontroller-gpio-configuration-for-hardware-settings-and-lowpower-consumption-stmicroelectronics.pdf

[timid plover]

maybe someone else will find it

[simple fractal]

i see sask power is saying 'Customers across the province will receive their smart meters during the next few years as supply allows.'

so 'eventually'

[warm pulsar]

Looks like a useful checklist for pretty much any processors

[simple fractal]

Here in BC there was an amount of hesitancy about smart meters.

[warm pulsar]

Here in SK too. Had them in Toronto as they were doing different rates depending on the time of day.

[eager matrix]

I'm curious. What is the hesitancy about? Also, hi Canadian neighbor. I live about a mile from the Peace Bridge in Buffalo.

[simple fractal]

https://www.cbc.ca/news/canada/british-columbia/bc-hydro-smart-meter-installs-violating-privacy-report-1.1016341

There was some idea that the meters could be hacked to allow thieves to determine that you were away.

[strong acorn]

there is an S2 version with two USB ports

[eager matrix]

That make sense in order to give incentive to switch optional usage to non peak times. It means they don't have to build more hydro plants to cover peak loads. Do they call electricity "hydro" across Canada or is that just Ontario?

[simple fractal]

Hydro Quebec, BC Hydro, Ontario

[upper sandal]

there is the Gravitech Cucumber boards that I know of

[strong acorn]

also skinnier, fits on breadboard with a row to spare on each side

[simple fractal]

i have a few S3 devkits. no time to do much right now

[warm pulsar]

Here in Sask, we can't really call them hydro as most of it is from coal. I still call them hydro...

[strong acorn]

hard to tell on Digikey, but Espressif N4R2 ESP32-S2 DevKit-1-C

[timid plover]

The dallas reverse engineering showed how the power could be shut of remotely also.

It's interesting, I believe Ontario has more nuclear that actual hydro.

Also for you both - I super loved Corner Gas.

I didn't know it was busted.

[shell mason]

let the ESP32 ordering party begin

[fair fulcrum]

yea, i though you had one of those

[cinder wind]

ahh one port for hardware uart, one for native usb? yeah that's useful for debugging

[strong acorn]

ESP32-S2-DEVKITC-1RU 1965-ESP32-S2-DEVKITC-1RU-ND with uFL

[eager matrix]

It was kinda weird that Espressif didn't put a 2nd USB connector on the Saola.

[warm pulsar]

Once upon a time, there was the ESP32. Now there are a thousand of them...

[shell mason]

S2 C3 and so on

[strong acorn]

should be same without "U" for non-uFL

[warm pulsar]

yeah but add RAM and Flash and that gives you a couple more multipliers

[simple fractal]

that board should have 2mb psram

[shell mason]

more multiplayer funfunfun right?

Sound good on YT. Today I'm driving the FeatherS2/TFT Featherwing Frankenportal.

[grand tusk]

Now I'm playing Product Roulette: Pick a random number, see if there is an Adafruit product for that number. All via the PyPortal framework.

Just pulled https://adafruit.com/product/5358 DIY Magnetic Connector.

Looks like the James Webb tracker API server is working today.

https://api.jwst-hub.com/track

[inner spade]

If the mag connectors are reversible, you’d need 7 pins for Stemma.

If reversed, you’d need symmetry by duplicating 3 of the four Stemma pins.

[grand tusk]

The magnets prevent reversal. Only connects one way.

[inner spade]

Ah, magnet polarity?

[grand tusk]

Yeah.

[inner spade]

Nice!

[inner spade]

I can fix the version when I get back to the studio later today.

Planning to update Adafruit touchscreen with the automatic rotation scheme, as well.

Synchronized touch with display.

Calibration too

There are two simple tests, one for legacy, one that’s the same as Adafruit touchscreen

A fingernail works too.

[grand tusk]

Product Roulette https://gist.github.com/rsbohn/83a632c81d44841aa6a952fcbb8efa4b
Displays random Adafruit products on PyPortal.

[inner spade]

It’s looking for min max values near the edges.

That’s the technique

[grand tusk]

I'll have to give the touch screen calibration program a try.

Could you store the values in NVM?

[inner spade]

They don’t drift much. Temperature is the primary issue.

But most fingers are larger than the drift.

That’s a legacy test

Calibration wasn’t used but could be added.

Trying to keep it the same as touchscreen button test

Yes, should be black with button.

Was tested with the M4

Paint demo is ancient legacy code

The wing’s reset button presses against the desktop.

The controller chip is obsolete, too.

Thank you for the review, @smoky island !

[ionic garnet]

hey y'all

[desert orbit]

So cool to see the qt py/bff form factor family growing 🥰

[ionic garnet]

indeed'

I love this form factor

nuff gpio for most of my current projects

[desert orbit]

Almost all the tiny of trinket with just enough extra room for tons more chips/options like wifi and stemma qt ☺️

[ionic garnet]

what is the enclosure Limor is using?

where she docked the board

[desert orbit]

It’s a prototype bff board I think?

[ionic garnet]

I have something like that but with Groove connectors

yes is it available?

want!

the display looks pretty nice

wow looks good

[desert orbit]

Sourcing tft/oled displays for these kinds of form factors seems like it could be difficult

That’s a nice display for emulation for sure

How is the tft wired up on the board? Parallel with slow GPIO handled by the GPIO expander?

Might’ve missed that part if it was explained already

Thanks for the SPI vs 8-bit explainer, been wondering about that for awhile 🙏🏻

[ionic garnet]

ah I remember dma and latching the display from way back in the days of CP/M computers when I wrote drivers for that and later DOS

[nova totem]

I believe the RP2040 with PIO can do 8 bit DMA but been a while since i coded that

The Great Search - Slim TRRS Headphone Jack
https://www.digikey.com/short/40n7fbp9

For our little QT Py gamer, we want to have an onboard headphone jack that folks can plug into to get audio out. Last week we picked out a headphone amplifier chip. This week we'll be sourcing a headphone jack we can use that will be slim enough to fit between the headers.

[ionic garnet]

why do i always sing along to that

[nova totem]

I had the eye on npi song in my head one night when i woke up at like 3am

[desert orbit]

Because it’s the most catchy jingle ever. You’re not alone in singing along! 😂🎶

[ionic garnet]

I also go new, new, new, new, new

[rotund marsh]

Need tiny efficient 16V DC to 5V DC converter for ESP32 Qt Py project. Best I can find so far is %97 DROK synchronous rectification. Any idea what synchronous rectification chip they use?

[urban gale]

I sing The Great Search whenver I'm looking for something in my shop

[ionic garnet]

nice

[nova totem]

especially when your epoxy bottle falls over and slowly leaks out over everything

[drifting wyvern]

I don't know the efficiency but there is an mpm module they sell on a breakout, it's used on some really new Arduino

[grand tusk]

I like chromium dioxide tape.

[open surge]

I have "SEEEGGGAAA" stuck in my head from when ladyada showed Sonic. I loved my Sega Genesis when I was young.

[open girder]

we've seen it easily attach to metals, wood, plastic, rubber and it wont dry out and peel off like most foam tapes. It's super strong, to the point we often feel kinda weird when we use it because don't expect such incredible tensile strength. You can even build a push-scooter that is kept together just by VHB Tape as seen at https://www.youtube.com/watch?v=rxJ-kU6Z8GY

[drifting wyvern]

3m pulling some kind of scam getting vhb on the new pages 😁

[desert orbit]

I mean, it’s incredible tape. I’ll allow it 😂

I’ve used different VHBs for cable management mount points in different scenarios and it’s always way outperformed my expectations, assuming the surfaces are decently oil free

[rotund marsh]

Any ideas what the "IAGCM" chip is here? Product Description: (Drok on Amzn) Mini Voltage Reducer DC 4.5-24V 12V 24V Step Down to 5V Buck Converter Board 3A Volt Step-Down Transformer Power Supply Module

Am trying to make PCB for my ESP32 qt py to mount, want PCB to handle 16V DC to 5V DC synchronous rectification. I can solder these, but figure this is a common scenario and there's a cost effective efficient schematic I should use?

[drifting wyvern]

Wow I didn't realize that stuff was that strong

[desert orbit]

Looks like a buck converter controller, not sure which off the top of my head

[drifting wyvern]

Is it maybe a TI chip? Their power chips have maddeningly unrelated silkscreens

Though they prefer qfn

[desert orbit]

Not exactly the same but I think this great search from awhile back talked about similar ICs: https://youtu.be/xHGRiLd7_VA

[drifting wyvern]

Have a good week everybody!

[nova totem]

so don't get it stuck to your arm hair, got it

[desert orbit]

👋🏻

[grand tusk]

My TFT was loose so I put superglue on it. That was a mistake.

[drifting wyvern]

Oh yeah

Super glue is often a mistake, it off gases and discolors so much stuff

[desert orbit]

Some of my most educational maker mistakes involved failing at the “CA glue or tape?” game 😂

[ionic garnet]

bye folks. Have a great week. Thanks Limor and PT

[inner spade]

Thanks!

[desert orbit]

Thanks limor and pt and chat buddies! Hope you all have a great week

[ionic garnet]

agreed on all points.

[drifting wyvern]

Ah here's the part/chip I was thinking of https://www.adafruit.com/product/4739

Integrated inductor

There's a 3v3 version too

[desert orbit]

That board is so cool, love that it’s pin compatible with the LM1117

[drifting wyvern]

Yeah I probably should throw another one or two on my next order because I'm probably going to embed my current one inside some equipment soon. It's a very nice thing

(and if you want to diy the whole board it didn't look too hard to lay out)

[rotund marsh]

This looks neat, thanks for the recommendation. Ideally trying to find something with 2A limit. Checking out the datasheet, specs and board layout (https://github.com/adafruit/Adafruit-MPM3610-PCB). So grateful that Adafruit Team share those. Cheers!

[desert orbit]

I think I remember that chip series having a higher output current model, maybe the MPM3620? Might work, but may not be available in a ready to use breakout

[rotund marsh]

Thanks @desert orbit. Currently digging around lcsc.com for small cheap efficient, and available... synchronous rectification chip/parts to copy-paste onto my 1st PCB design. A laughably basic board for a ESP32 QT PY to be seated and control some lights, nothing fancy.

Using EasyEDA, JLCPCB to Fab, with SMT assembly for most/all parts, their LCSC part search/picking integration has been helpful. Am clueless, but know enough to appreciate how great Digi-key's search query features are. Look forward to LCSC improving theirs.

Learning about PCBs by example from Adafruit's github repos, https://fritzing.org/, https://oshwlab.com/search?wd=synchronous, and YouTubers like "GreatScott", "SDG Electronics", "atomic14". EEVblog has a lot of knowledge, but info delivery is less dense/edited, hopefully folks like Dave will eventually scale to unlock the value of info in their content and outsource editing and re-releasing their content in a more curated format.

[desert orbit]

Nice! You’re off to a great start! Check out the #help-with-hw-design channel here too, good folks in there 🙂 Some other YouTubers I’ve learned from I can recommend: Voltlog, Marco Reps, Signal Path, Unexpected Maker, Fran Blanche, CuriousMarc. Information density/value may vary but I’ve learned a lot from them as well as the ones you’ve mentioned 🙂

[rotund marsh]

Awesome! Thanks for the ptrs @desert orbit !

[desert orbit]

No prob! There’s something really satisfying about getting those first boards from JLCPCB or PCBWay. Hope you have fun with it!

[rotund marsh]

Yep, looking forward to it. Blows my mind am lucky enough to live at a moment in time and space, where I'm fortunate enough to be able to turn an idea into reality. Cheers!

[mighty kestrel]

@haughty quiver
Long time ago during your excellent Product Pick of the Week 11/16/21 Latching Relay FeatherWing, asked about what happens if you put BOTH UNSET & SET pins to high at the same time.

#live-broadcast-chat message

Finally got round to testing this ... So sorry for the delay!

It seems ( at least in my setup ) that when you put both pins to high whatever state the relay was in PRIOR to doing this is maintained!

If Relay was active then it stays active - if it was inactive then it stays inactive.

Maybe not the most useful result but at least it appears that if both are set high at the same time , say by accident, then at least the relay maintains a predictable, consistent state

[inner spade]

Can check for existence of touch pin in board

[inner spade]

@smoky island Fun project! Thanks for the stream today.

[haughty quiver]

[sudden gate]

Thanks @haughty quiver for another one - bring back the drawer openings… lol

[haughty quiver]

That's so 2021

[ionic garnet]

the problem I have had is where the wires are soldered onto the battery. I've had at least 4 Lipos come unsoldered. I fixed a couple but not all

first time it happened I was scared to solder back on because I was afraid the heat would 'splode the battery

[haughty quiver]

ah, yes, I've been there too @ionic garnet

those things are so easy to snap off if you aren't very gentle with them

[ionic garnet]

I've also gotten confused about swapped wires on some brands. I only use Adafruit brand now.

Yeah. There's an Elvis Costello song called "Let Em Dangle" that described how I treated lipos early on

I really love that song. From his album Spike I think

it's kindof relevant to today's polarization of peeps

[sudden slate]

Yesssss

@open girder question: how can I connect analog out of mcu boards to speakers or mic input? (change voltage)

[open surge]

/wave

Thanks pt! Should be in podcaster apps by the end of the week

[rapid hornet]

excited to record tomorrow!

[cinder wind]

yay CircuitPython Show!

[open girder]

@shadow sigil thanks, will get to this at the end when we do questions!

@open girder Question: What are "jellybean parts"? I just heard this on a podcast, too.

[turbid hill]

generic parts such as reisitors or caps or basic 555 timers

[robust horizon]

twisting is a common way to remove SMT capacitors! not good

[turbid hill]

that is just being mean to the smt part

you can click those terminals block together

[placid crest]

Tighten the screw on stranded wire the wait and do it again. Wires move and can loosen. Great Show!

Maybe someone will make a 386 emulator for it!

[dim wigeon]

Could be! I think it has the same amount of RAM…

[strange mantle]

[slow spire]

@dim wigeon Wow, looks like someone did one for the original ESP32: https://hackaday.com/2021/07/28/emulating-the-ibm-pc-on-an-esp32/

[scenic prawn]

Buy this with the 3M VHB tape.

[dim wigeon]

@slow spire That’s wild.

[turbid hill]

@open girder you have made a lot of news sites with the tiny doom player

[open girder]

whoops device first, then floppy

[slow spire]

OOOOH!

[waxen thistle]

I'm loosely paying attention, then I hear the Dragon Warrior 1 title theme and my ears perk up like a puppy dog hearing a new sound....

[strong acorn]

❔: Do the different ESP32-S2 boards and modules that Adafruit sells differ in flash or RAM speed? On-chip vs. in-module vs. separate chips? (I see differences in overall code execution speed across device types)

[echo canopy]

Question for the show ….. @open girder

Apple AirTags have been making the news recently for being miss used…. Is it possible to “see” them with NRF52’s and have code analyze if it’s a new MAC address and has also been around you for x amount of time ? For an alert 🚨

[robust horizon]

@strong acorn CircuitPython will run the core at the same speed in MHz, but it does seem likely that there could be differences in access time to the SPI flash & psram. I haven't ever tried to measure it myself.

[strong acorn]

I do see variance in overall code execution across board types, so wondering. Flash seems all QIO (?), not sure about PSRAM.

[waxen thistle]

iddqd idkfa

i can't remember where I put my keys, but I can remember those cheat codes from all those years ago

[cinder wind]

tape over the write-protect hole!?! hacker!

[robust horizon]

@cinder wind I think it's actually over the density detect hole

notice the non taped one has the slidy black plastic bit

[winter zinc]

Question: With the chip shortage, any chance of getting the 3 older TFT featherwings back in stock?

[cinder wind]

oh! right! I used to use a hole punch to do something similar on Apple ][ disks. (oh no wait that was to make it double-sided I think)

[shy topaz]

Any chance of SCSI emulation?

[nova totem]

Wasn't it for both? Cover/punch left side for the front, punch the right side for the back?

[vital grove]

Could there be a filter feature on adafruit learn to go through all the projects

[robust horizon]

@strong acorn do you want to mention two specific boards you were comparing for speed with the esp32-s2?

[scenic prawn]

are you looking forward to any upcoming display tech?

[shy topaz]

I had a paper punch on a keychain reel attached to my belt.

[slow spire]

Pretty sure 3.5" floppies didn't have logically separated sides

[strong acorn]

cool, thanks!

[nova totem]

Oh yeah I was thinking 5 1/4

[strong acorn]

@robust horizon I'll put something together, comparing boards with same amount of PSRAM.

[manic shard]

Question: does digital accelerometer exist, that doesn't use ADC

[strange mantle]

no ADC at what level? there are accelos that talk over I2C and SPI for example.

[digital crescent]

what backend language is used for adafruit.com?

[upbeat coral]

Thank you for taking time for us.

[slow spire]

I believe many of Adafruit's IMUs and accelerometers use digital (I2C or SPI) interfaces

[manic shard]

At the level of analyzing data

[viral sail]

Thanks @open girder and good night. 🌘

[ionic garnet]

Have a great night @open girder Limor and PT

[placid crest]

Good night!

[slow spire]

Thanks, @open girder!

[turbid hill]

[tulip canyon]

Thank you again. Have a good one everybody

[cinder wind]

bye everyone! thanks for the livestream @open girder!

[waxen thistle]

Thanks for another excellent evening of shows @open girder!

[split gazelle]

Thanks for a great night of shows!

[robust horizon]

@strong acorn with a debug build I think the early messages will print out a bunch of info about the SPI settings for flash & ram

[balmy tinsel]

have a good one all! Stay safe

[dim wigeon]

Thanks everyone!

[ionic garnet]

Yes need people in person.

[strange mantle]

@manic shard like this maybe?

TaTa

[manic shard]

I know that transferring data from sensor to main chip is mostly used by the protocol. I am curious about high precise digital accelerometer, that doesn't use ADC for analyzing acceleration

[strange mantle]

not sure. if you're wanting do get the readings into a digital computer, conversion from analog will need to be done at some point.

[strong acorn]

it does print some basic info even without a debug build (my build env is hosed atm, need to dedicate some time to rebuilding from scratch)

e.g.,```
I (25) qio_mode: Enabling default flash chip QIO
I (30) boot.esp32s2: SPI Speed : 80MHz
I (35) boot.esp32s2: SPI Mode : QIO
I (40) boot.esp32s2: SPI Flash Size : 4MB

...

I (885) spiram: Found 16MBit SPI RAM device
I (890) spiram: SPI RAM mode: sram 40m
I (895) spiram: PSRAM initialized, cache is in normal (1-core) mode.

[manic shard]

ok. thanks

[grim ginkgo]

😂 I'm watching the Show and Tell of last night. Shortly showed my son the super cute back mounted robot 🤖 and let him carry on what he was doing... Then he heard @ladyada talking... "Is that the woman from the Mandolorian?" ||We watched the Book of Boba Fett last night. I don't know whether Limor ever dated a Jawa, but if there's someone in this Galaxy that can turn Jawa scrap into cool stuff, it's her. ||

Hello all.
Curious to know if there's anyone watching that doesn't know what a rotary phone is. 🙂

No sound

[lavish patrol]

Mic! Mic!

[drowsy inlet]

Lost audio prior to parsec

audio good now

heard song

[lavish patrol]

Audio's fine now. 👍

[inner spade]

🎙️ is working!

[drowsy inlet]

neat parsec

[lavish patrol]

Buffering...

Fine now. 👍

Could have been at my end. 🤔

[idle spindle]

hello im here. still cant implement the rgb code in to kmk lol if i keep at it ill get it.

[lavish patrol]

Good old Bakelite.

[midnight plinth]

Nice screwdriver

[cinder wind]

Rotary phone is what my BLE-enabled Dremel does I think

[lavish patrol]

Lol

[inner spade]

A little 5v solenoid could ring the bell domes nicely.

[sinful meadow]

debouncer requires ticks now

[shell mason]

lars effect

soon lars calling

[inner spade]

timeout = the shortest start-to-end dial sequence, such as dialing "1"?

[lavish patrol]

Some bloke in Connecticut: "Hello? Hello?" 😄

[shell mason]

see lars give the blessing for the dial rotary phone

[midnight plinth]

You can get the jacks from here https://www.oldphoneshop.com/products/500-and-2500-modular-jack-set.html

[shell mason]

great tip Franklin

[lavish patrol]

I'm starting to hate those things with a passion.

Ever since I discovered WAGO connectors.

[midnight plinth]

Don't forget the dustcover if you plan to close it up.

[inner spade]

Tapping the hook was a theatrical way of getting the operator's attention. ☎️

[shell mason]

Who is there? A: Lars is here

[midnight plinth]

Some times I think this is the only reason of a cell phone. pictures before repair.

[lavish patrol]

Lol. You can use your cellphone to help you repair your rotary phone. 🤔

[lavish patrol]

Hello, @clever summit 👋

[sudden gate]

Thanks @haughty quiver !

[lavish patrol]

Thanks, @haughty quiver 😀

[glass stag]

Have a good day.

[inner spade]

Very nostalgic! Wondering if the phone's modular interface jack could be all that's needed to sense dialing rather than having to open the case. @haughty quiver: have you looked into that?

[glass stag]

Thanks @haughty quiver

[inner spade]

Thanks!

[solemn cosmos]

Bye

[haughty quiver]

@inner spade ooh, great question, I'll check

[viral sail]

Thanks @haughty quiver

[midnight plinth]

213 was my area code but 73x was the area i was working in at pactel.

[haughty quiver]

makes sense that the pulses would be sent down the line

[inner spade]

Yes, since the off-hook / on-hook switch can dial, too. That's why the dial mechanism mutes the low-impedance audio circuitry; removes it from the line connection whilst dialing, I believe.

[sudden gate]

Of course , who doesn’t enjoy an opening of something so old 😊

[sand frigate]

Loved this project, have an old rotary I’m going to crack open and see if I can do the same. Would love to integrate this in with the macro pad to use as a ‘soft unlock’ of the macro pages for password storage. Over the top but that’s the fun on it 😛

[haughty quiver]

heck yes!

[ionic garnet]

gish dorn it. I missed JPWS.

@haughty quiver hey how would you use a diode matrix keyboard for MIDI. your pico midi keeb guide code has pull down switches for all of the notes. how would i make it work on a matrix instead.

[grim ginkgo]

This takes me back to blue boxing on my Amiga. Dialing toll free AT&T numbers in Asia where the phone exchanges still listened for commands on the line, and then sending the right tones to simulate hang up and patching through to the BBS number in the US I wanted to visit. I hardly ever connected at the 14k4 baud HST that my US Robotics modem could do, because of the lousy line quality and detour via Asia. But it was "free" because my own phone company thought I was dialing toll free.

I didn't actually own a hardware blue box but had an implementation in software

I'd hold the hand set next to my 1084S monitor until I heard the modem handshake succeed.

[ionic garnet]

hey random question at random time posed to you all randomly: has anyone ever created a list or repo of the best examples of animations for neopixels (or any addressable color LEDs) using CircuitPython or Arduino C/C++ code? Besides seeing cool stuff other people have done I'd love to put together a small set of animations similar to the typical controllers that come with ws2812b/neopixels from companies like BTF Lighting Govee, or similar. These typically have dozens of animations and color palettes you can iterate through or save as favorites. Up until now I have used both a controller provided by the ws2812b vendors and a microcontroller-based system with a way to switch which one is the active controller of the strand, matrix or ring.

[clear matrix]

Have you seen the LED Animation library for CircuitPython?

Not sure if that's what you're looking for.

@eager matrix You can even post on the forums, a few people did

[eager matrix]

Cool. I'll do this over the weekend.

[open surge]

Thanks foamyguy!

[modern night]

The JIT is such a silly idea but I figured I'd think about it and mull it over. It's a flag so the compiler treats the following code differently, which means it'd be a headache and a half to add to the core

Also Just In Time might be the wrong thing to call ithttps://numba.pydata.org/ *shrug*

@eager matrix thanks for the reminder.

[grand tusk]

FORTRAN support?

[eager matrix]

Funny, my blog pic is a punch card.

[clever summit]

🇸🇪 👋

[eager matrix]

Hi sis.

[modern night]

Decorator! That's the word I was looking for! (And now the word I get to look up 😄 )

[sterile forge]

I used 8 inch floppy's on IBM system 3 and my Imsai 8080.

[dim wigeon]

I’m not quite old enough to have used 8 inch floppies on computers, but in college I was a broadcasting major, and the TV studio’s character generator used them.

[random lodge]

I used an IBM with a cassette tape

School

[eager matrix]

I may do that. I love audio stuff.

DSP is my thing.

[cinder wind]

I would love to see Teensy Audio Library ported to CircuitPython

[nova totem]

People always ask for UDP support... but never sure if anyone is listening 😂

[cinder wind]

Limor et al already ported it to SAMD51 (in Arduino)

[eager matrix]

I'm also going to make an audio feather wing with 2in and 2 out and might do balanced inputs if I can fit the connectors and get the chips.

[cinder wind]

yeah static buffers

[eager matrix]

I may need some help getting set up. Is there a guide?

[modern night]

Do you have books you recommend that are helpful? I might just end up printing out the guide

[rapid hornet]

https://learn.adafruit.com/building-circuitpython

[grand tusk]

I've seen several people trying to do ultrasonic over I2S. 🤷

[eager matrix]

I'm on it right now.

[cinder wind]

wait what's the UDP joke? I think I missed it

[nova totem]

I could repeat the joke but still wouldn't be sure if you'd get it

[modern night]

Just books that help with problems you run into with core development. I've discovered that reading through books is one of my preferred learning methods

[eager matrix]

Or you could repeat it a bunch of times.

[dim wigeon]

This meta-humor is too much for my brain on a Friday of a week I’ve been on call for work. 😂

[grand tusk]

NAK

[nova totem]

I'm not sure of any. The discord I find is the best bet and there is usually someone around

[sterile forge]

UDP does not check to see if packets arrive in order or at all.

[rapid hornet]

https://twitch.tv/tammymakesthings

[dim wigeon]

I’m hoping to get all the rest of the streaming mechanics figured out this weekend.

[modern night]

Yeah, that's what I was thinking. But I was wondering if there were any books that stood out. The guide is awesome and a great place to start so it's not like I'm hurting for options 😅

[dim wigeon]

I was super excited to get involved with CircuitPython in 2019, and then the world blew up and my body tried to assassinate me last year. Now I’m excited to get back into the community.

[timid plover]

I'm reading Jan's USB Complete now! very good

[modern night]

Awesome! Thank you!

[eager matrix]

Phils Lab has a Kicad tutorial on udemy and it is free for a few days.

[cinder wind]

I'll have a "CircuitPython2022" post but I'll be done maybe this evening, and it's really just "more audio control plz kthx"

[grand tusk]

Will ampy be supported for ESP32S3 workflow?

[open surge]

We might just have to talk about that todbot. 🙂

[eager matrix]

Oh smack, the free ones ran out about an hour ago.

[cinder wind]

I am almost able to write native CircuitPython libraries now that dig into system resources

so maybe I can work on audio stuff

[balmy tinsel]

I'm relatively new to using Circuit Python and haven't had a chance to write a CP2022. It's great for the keyboard stuff I've used it for I'm wanting to try it for some robotics related projects.

[upper sandal]

an issue with ampy is that the latest imports ubinascii to be binary safe, Jerry has filed a PR for that

[dim wigeon]

I don’t know if I know enough of the low-level stuff to contribute to the audio stuff, but it’s something I’m interested in too.

[eager matrix]

Oh man a looper would be great esp after I finish my board.

[nova totem]

I wonder how much of the audio stuff can be done port independent. I know a bunch of it ends up port specific which makes the work harder

[grand tusk]

File transfer over I2C?

I want a swarm of multiprocessing CircuitPython boards.

[dim wigeon]

@grand tusk Do you want Skynet? Because that’s how you get Skynet. Skynet runs on CircuitPython. 😉

[grand tusk]

I've been accused of that before.

[nova totem]

depending on the math needed the hard stuff gets into the port specific code

[dim wigeon]

I don’t mind diving into stuff I don’ t totally know how to do, but I’m not a math ninja, so…

[grand tusk]

Kick on voice 0, snare on voice 1. Mixer works pretty well.

[eager matrix]

Are there Kicad parts defined for the feather connectors?

[warm pulsar]

@eager matrix what do you mean by feather connectors? to create your own feather - or to use one in your project?

[brazen grove]

@idle spindle try them first with one of the examples from https://github.com/adafruit/Adafruit_CircuitPython_NeoPixel

[modern night]

that'd be fun

Yeah the broadcast net stuff would be a fun thing to see

I am going to make a feather wing for audio. I'd like to not need to define the headers if there's already a part for them.

@eager matrix yeah, the spec is online but I wouldn't be surprised that someone already created the necessary footprint for one.

I aspire to that low-power lifestyle.

[cinder wind]

a circup non-believer! get him!

[eager matrix]

I'll talk to @ornate coyote and the peeps from Blues Wireless to see if they used Kicad.

[modern night]

haha, workflows are hard things to change though

[ornate coyote]

You can just import the eagle files for any of Adafruits feathers. Eagle import in KiCAD 6 is awesome.

[eager matrix]

I've been a vimmer for decades.

[grim ginkgo]

That explains why I couldn't import pdb 🙂

[eager matrix]

Awesome.

[grand tusk]

Maybe this: https://github.com/adafruit/Adafruit-FeatherWing-Proto-and-Doubler for featherwing footprint.

[inner spade]

The footprint is fairly easy to create. I have a few different 2- layer designs with custom silk layers. (In KiCAD)

[warm pulsar]

@ornate coyote Good tip! One more reason to upgrade to Kicad 6! I've been looking to create a feather...

[eager matrix]

This conversation show why this discord is great.

[warm pulsar]

@eager matrix A few of us have been having multiple conversations in parallel...

[eager matrix]

Cool. Where's the party?

[dim wigeon]

@warm pulsar You mean there are people whose brains allow them to only have a single conversation at a time? Sounds fake to me. 😂

[grand tusk]

Cut off one head, two more will appear.

[ornate coyote]

KiCAD 6 is da bomb !!

[warm pulsar]

@dim wigeon It all depends on how many IDE you have opened at the same time. (trying to code at the same time too - without much progress)

[timid plover]

What's your standard-work reguarding compiler warnings ? ( saw some flow by )

[ornate coyote]

w00p! Just finally did a PR for my new S3 boards for tinyuf2!

@rapid hornet remember that magic you did on the CPY repo to not build every boards on every PR? Time for that to happen on the tinyuf2 repo I think... had to run 50 builds (49 unrelated) to check my PR?

hahaha, you've seen my git fu... it's non-existent !

[warm pulsar]

@ornate coyote looking forward to those feather s3... Will they end up on tindie?

[ornate coyote]

Working on that RIGHT NOW!

[dim wigeon]

I need to figure out a better way to organize all my boards. I have microcontrollers scattered all over my house right now. 🙂

[warm pulsar]

sweet. I'll have to load my basket

@dim wigeon sensors all over the place makes things even worse... They DO get everywhere...

[ornate coyote]

Tindie is the same as my website (both ship from me). but likely not on tindie immediately as silicon is in short supply.

[dim wigeon]

@warm pulsar They really do. I also somehow have a bunch of oscilloscope probes all over right now too. (I just upgraded my scope, but still…)

[ornate coyote]

@rapid hornet it does have an internal temp sensor yes. Not sure how to read it.

https://github.com/espressif/esp-idf/blob/master/docs/en/api-reference/peripherals/temp_sensor.rst

not in 4.4 yet is seems.

4.4 is now officially released (a few days ago) so maybe that's old.

[idle spindle]

@brazen grove i have played with them for a while now. ther WS2811b Or what ever the stander 5v ARGB(neopixel). they work my code dose not.

[brazen grove]

do they work under circuitpython though?

[idle spindle]

yes lol not trying to be rude. i love making stuff and playing with CP. im learning CP but im coming from arduino. neopixels and my fav to play with in both. yes they work in both.

i have a strain of 21 that i was playing with the led animation lib last night

i can get the code right

cant

the board works just cant get the code right sorry to say so much lol

this is what im beating myself over

[warm pulsar]

@rapid hornet is 0 = forever? or 32bit_max is practically forever

[grim ginkgo]

Are you asking us to solve the halting problem?

[ornate coyote]

sorry to keep you awake @rapid hornet 🙂 Feel free to sleep on stream! I do some weeks and folks don't even realise 😉

[timid plover]

what are the units on the timeout value ( microseconds ? )

[cinder wind]

CP =? NP

[timid plover]

that is a long time then

[ornate coyote]

Friday afternoon yawnies 🙂

[sinful meadow]
