Mike G and Uma are adding reused #WS2812 LEDs to the comet today @DoESLiverpool - tools and materials laid out neatly!
Looking forward to seeing this with soft plastic light diffusing flames made at the Convenience Gallery workshop at Pilgrim Street Art Gallery this Friday

I put #micropython on one of my #M5Atom #ESP32 devices - just to see and play with it a bit.
I used the new #Arduino IDE for python - And I still don't like #python - I will use it when I have to but, it's not for me. I also know it's going to be the future - so I will just have to be stuck in my ways.
It did work thou, and I was able to get the #ws2812 demo working on the Atom - without too much problem - it didn't like the idents for the first for statement thou?

Been working on a new Gameboy Macro build, I found some super tiny Ws2812 led strip and found that they fit in my hollow hinge bar defuser I had made for another build. It does screen switching and has usb c charging. The Ws2812 strip is controlled by a attiny85 #Nintendo #gameboymacro #ws2812 #arduino #attiny85

A fun but challenging model kit I've been working on and off on and adding to for a while.
Paperboard kit of the Hogwarts Express train plus station, Harry, Ron, and flying car:
https://www.4dmodelkit.com/products/harry-potter-hogwarts-express
The train and tracks are almost 3 feet long.
I added an #Arduino Nano with the #Adafruit #Neopixel, #Mozzi, and #Talkie libraries, piezo speakers, and #WS2812 LEDs to give it music, sounds, and flickering engine, coalbox, and passenger compartment lights.

Something I haven't yet seen (but seems to be quite common) is (ab-)using the #SPI to produce the waves for the DIN for the LEDs:
To recap, SPI uses SCLK, PICO/MOSI, POCI/MISO, CS/SS for communication, that is clock, data to and from peripheral and chip-select. The LED stripe only uses one "data in" port however, with a peculiar square-wave protocol that requires precise timing. One popular way to achieve that is to program the SPI to leave SCLK, POCI and CS unconfigured and only hook up PICO<->DIN. Further, since the SPI works at roughly 4x the speed the LED strips operate, to send one bit of value X over to the LED, you need to tell the SPI to send four such X valued bits.
Now I need to figure out whether the Rust crate for this allows "empty" or dangling SPI GPIO Pins as well...

Some articles around this technique:

There are some people basically doing the same in hardware:
