I used a #qtpy #esp32 from @adafruit to make a small #iot stoplight. I also wrote a tiny app and deployed it on my #homelab. So now when I'm in meetings, or deeply focused on work, I can avoid disruptions #wfh
kind of excited to finish a project end-to-end instead of bailing at the first friction point

@mich_waveform I' ve been using QtPy as an abstraction layer for a few years, allowing transparent switching between pyqt6 and pyside6. It does make debugging a little bit more complicated and not sure if it is completely worth it, but it does leave my options open as to licensing.
Lastly, for #PyQtGraph developers, we now have stub files for getting auto-completion when using pyqtgraph.Qt, which is PyQtGraph's Qt abstraction layer. This layer is not intended to be used outside of #PyQtGraph, if you want a Qt abstraction layer for your project, we recommend the #QtPy library.
We have had a stub file there for a while, but it only worked in PyCharm, the stubs now work with pyright and PyCharm now.
I’m pretty proud of my THX Deep Note sound recreation attempt, which I realized I only posted on Twitter (RIP). So I upload it to Youtube & here. The Mozzi synth library is great and it was fun getting it to do this. And thanks to Mike Rugnetta for getting me near the rabbit hole of the THX sound!

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! https://www.printables.com/model/757087-case-for-qtpy_synth-circuitpython-synthesizer

Bottle Piano.
A MIDI controller made of bottles, glitter, and @adafruit@tweet.pasture.moe @Raspberry_Pi@raspberrypi.social RP2040 MCU (and based on an original idea from Adafruit).
Coded in @circuitpython .
Our this year's MusicJam project.
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!

Oh yeah, wavetables can now be selected on the fly! Also, MIDI! This little CircuitPython QTPy synth is a lot of fun. This demo shows a handful of wavetables being explored, mostly from #Braids and #Plaits Eurorack modules. Left knob selects wavetable, right knob scans through selected wavetable. Now to fix up the messed up UI!

The second (of 3 PCBs) Xiao/QTPy breakout works. This one was a bit more complicated to hand solder. The RV3032 RTC is tiny and the 0.5mm FPC connector is tricky too.

Did I ever show this? Turns out because #ESP32 has super-configurable pins AND because the #adafruit #QTPy / #Seeed #Xiao format has castellated pads, you can just solder an I2C OLED display right on top of it and it works! Since this is an #ESP32S3 QTPy, I use this to test #CircuitPython WiFi stuff. Lately I've been using its as a Multicast UDP emitter 😀 Code for this demo: https://gist.github.com/todbot/31272a914df7f856b088671943b5ed35

Tree of Life Branches Out with a Twist
In the middle of 2020, [charlie] challenged himself to conceive of and finish one project every month for the next twelve. Here we are a year later with [charlie]'s last project of the challenge: a tree of life with a bit of a twist to it.
The idea was to build a tree with lights that would represent the leaves and change as the tree went through the seasons. After a lot of searching, he found a really elaborate model meant for CNC carving, but the model maker converted it to an STL. [charlie]'s original plan was to poke the LEDs through the print. After consulting a wise woman, he decided to take the two-color approach and make the background translucent so that the 16 RGB LEDs can shine through.
So, what's the twist? Well, over time, the tree will develop dementia. One by one, the leaves will lose awareness and go through the seasons backward, or slow down their cycle, or speed up. Eventually, the entire tree recedes into a rainbow of confusion. Sadly beautiful, isn't it?
No printer? No problem. Trees of life come in all forms, including free-form.
