ok, I fit in one of the ws2812, I'm not confident the part is right, so thats enough for now, but all that spare room I had would only fit like a 2x3 array anyhow, so, whatever. (I can't draw anything on that)

Use a Raspberry Pi Pico, a Joystick, and a NeoPixel / ws2812 LED strip to create a one-handed "DJ Strobe" that can change colors & strobe speed. Issued as a CircuitPython challenge to my students who just learned to use a joystick, with a solution presented afterward. Hack on! youtu.be/iidICu-8QXk

(I am now developing quite the collection of unused crappy ws2812 inline controller boards that have been removed from cheapo "RGB lamp!" products after substituting an Arduino or ESP32 or the like.)

Finally got these, can't wait to try them out. WS2812 style addressable RGB LEDs but suuuper small. Basically like a square 0805 footprint.

It is pretty impressive, though the RP2040 only has two hardware UARTs, and I need to talk to three devices at the same time.
In 32-bit mode, my idea is basically DMA-over-Serial, piping in WS2812 values directly, with the leading byte (discarded by the WS2812 PIO block) used for control logic.

Using WS2812’s too - a 12 segment LED ring of them.

Been working on a Teensy 4.0 library which can capture and analyze timing of WS2812 LED data.
In this picture, Teensy #4 controls eight WS2812 LEDs while Teensy #6 captures high & low timing of every data bit.
Still work-in-progress, but initial code uploaded to Github.

I’m mostly trying to do this with stuff I already have. I probably could make 7 segment displays with ws2812 addressable LEDs that are much better.

Inspired by @alpenglow.bsky.social's WS2812 LED plushie, I made a WS2812 bag with three addressable LEDs and an @adafruit.com APDS9960 color/gesture sensor on the front, so the LEDs can pick up colors from nearby objects. Assembly is finished, just working on the code now.

Hey, Phil @gadgetoid.com 🙂
I'm hoping that you may be able to steer me in the right direction with something 🙏
I want to scroll text on a 'simple' WS2812 matrix (ie. a long strip arranged as a 32x8 matrix), using a Microbit 😬
Any pointers or advice would be very gratefully received.
Thank you.

Hello World! I guess we're trying this out now too. Hoping to connect with makers, LED enthusiasts, people who like circuits and PCB design, and folx who just have a little spark about building fun shit. #makersofbluesky #maker #electronics #solderingkits #leds
