I'm super proud and excited about this project!
My dear friend Allan approached me a couple months ago with the idea of attaching LEDs to this incredible vintage costume jacket. He envisioned strips of LEDs on the large lapels & drew me a napkin sketch over dinner.
Once I got the jacket, I mapped out where some pixels might go and how many I'd be able to get on the lapels, settling on using strips of 144/meter NeoPixels to get 120 pixels on the jacket.
I soldered together small sections of NeoPixels and arranged them into a matrix formation on either lapel, and drove the pixels with an Adafruit Gemma M0. The Gemma M0 is amazing and driving 120 pixels over two pins plus a button is so easy. This sketch only uses about 10% of the space on the Gemma M0, so there’s loads more space to add additional animations or power additional pixels. I could've used MakeCode or CircuitPython with the Gemma M0, but I really wanted to use FastLED.
I utilized Mark Kriegsman's special XY mapping code with FastLED to tell the Gemma the location of each pixel and run some incredible animations.
