  1. Tips on how to use CircuitPython in a bigger project with @prcutler and @todbot for #CircuitPythonDay happening now!

    youtube.com/live/uTl1KA2MPxI

  2. Hey @adafruit fam - too early to post #CircuitPythonDay content? If not, here's a build video on making Yoda talk phrases & answer Magic Eight Ball-style questions. Uses the @RaspberryPi Pico, a microSD card reader, the MPR121 capacitive touch board, and a speaker/stereo jack. #BuiltWithProfG Hack on! youtu.be/7ZfKEFuvWEY

  3. Pleased to see that after a heroic bit of sleuthing on @tannewt’s part, #CircuitPython audio seems to work great now on #RP2350. Maybe I will have something for #CircuitPythonDay2024 using it! The #SparkFun Pro Micro format is so nice

  4. Look at these beautiful little RP2350 jewels.
    Can’t wait to start hacking on them!
    Looks like they run the Pico2 build of #CircuitPython just fine!

  5. The “picotouch_drumcard” boards showed up today! I put some software on it too. A few gotchas in my design but I can make it work. Now on to sample playback, since this is labelled a drum machine after all

  6. Several folks asked if they could get the little capacitive touch wheels I made as a badge add-on giveaway for Hackaday Supercon 2024. Now you can get them in my Tindie store!
    Demo video of using two on a breadboard:

  7. More CircuitPython capacitive touch sensing madness w/ the Pico. Now I can do touch sliders and touch wheels. Is this board interesting to anyone else, should I put it in my Tindie store?

  8. I made a little 3d-printable case for my “qtpy_synth” test board to help me play with CircuitPython synthio (and Arduino Mozzi). It works pretty well, I like it better than the standoffs I originally started with. And now can have some cool matching 3d-printed knobs! printables.com/model/757087-ca

  9. Anyone else knows HID “System Control” commands or USB keyboard sleep/wake magic? I think I implemented it correctly in CircuitPython and seems to function mostly correct on Windows but on MacOS, it brings a "Are you sure you want to shutdown?” dialog. gist.github.com/todbot/5cd232e

  10. I ended up programming this one with Adafruit's #circuitpython, because they have a very easy to use #ds18b20 driver and wifi driver. My preferred #Rust framework, #embassy, doesn't yet have a 1wire implementation and it looked a little gross to write it for a one-off temp sensor. I'll return to this some time later; for now, I have a thermometer located near my thermostat that I can poke and get a reading from whenever I want.

    Also: The pi pico is a power hog but dang is it handy.

  11. Currently using CircuitPython on a Raspberry Pico W in an IoT research project.

    I've found when a sensor stops reporting, it is difficult to determine why, especially if we rely on reporting the errors over WiFi.

    The pico will blink twice every 5 seconds, which appears to be a way of CircuitPython to report a general exception occurred, even though we catch all exceptions.

    I'm curious if anyone has run into this and any tips they might have?

  12. A little demo of a project I've been working: I made synthesizers for every attendee of our Sketching in Hardware conference! It was a lot of fun "infecting" people with little musical noise toys. It's called "picotouch_synth" and it's an evolution of the CircuitPython synthio on Raspberry Pi Pico stuff I've been doing for a while now

  13. Video of wavetable scanning using this new visualization technique. I love it! The resulting images are so beautiful and I'm finding the visualization really useful. Making me rethink my little synth toy designs

  14. I'm working on visualizing wavetables for CircuitPython synth stuff. Can you match the image on the left and right? Pretty cool but wow such a different way to see these waves! (each horizontal line is one waveform from the wavetable) The Pygamer is a great tool for this exploration since it has (albeit, noisy) audio outs in addition to screen + keys

  15. The CircuitPython synthio panel was a lot of fun! Thank you @prcutler for organizing & hosting. Thanks to panel members John Park for the Intro to Synthesis at the start of the panel, @kattni for {musical/educator/synth}-using observations, @stylus for synthio deep knowledge, and to @adafruit for making it all happen! Here's a recording of the livestream: youtube.com/watch?v=SC4hUUfxVB

  16. More synthio fun! I took an existing CircuitPython algorithmic melody generator (bouncing balls on an 8x8 LED grid) and added a few lines of synthio. I also made it so it plays randomly in a scale (mixolydian) Thanks again for synthio @stylus!

  17. Time for another circuitpython synthio trick! This one's a fairly small sketch showing how to use wavetables in your synthio code. Modulating the wavetable position w/ LFO makes for such expressive tones. And we're hearing just 20% of the wavetable!

    1. The easiest way to get into microcontrollers for you is to buy @adafruit or and program it on , a limited version of .

    adafruit.com/product/4200

    2. will let you program anything and smartly utilize limited resources. Entry level is high.

    3. strikes the balance. It's easy to learn and with you can program any microcontrollers, including abovementioned pybadge.

  19. It's not the most musical, but here's a demo showing the complexity of sound you can get from synthio using two wavetables and simple modulation. Less than two pages of code!

  20. CircuitPython Happenings Hack Chat with Adafruit - Join us on Wednesday, July 26 at noon Pacific for the CircuitPython Happenings Hac... - hackaday.com/2023/07/24/circui #hackadaycolumns #hackchat #slider

  21. Very excited by this: morphing wavetable synth in CircuitPython! youtube.com/watch?v=4hgDi6MNfs It's still rough around the edges, but is sounding _really_ cool. Since it's wavetable-based, swapping wavetables gives the synth an entirely different character. (did you know of this awesome set of wavetables? waveeditonline.com/ Just drop these WAVs in the CIRCUITPY drive & get new sounds) All on a little QTPy RP2040! github.com/todbot/qtpy_synth

  23. How about a complete battery-powered MIDI monosynth in CircuitPython synthio? Three oscillator w/ 2-pole resonant low-pass filter. Great for basslines! Both USB & Serial MIDI. Responds to MIDI velocity & CCs to adjust loudness, filter, vibrato, and release time.
