My wife is a teacher and wanted something spooky but not scary to wear for this upcoming Halloween so I #3dprinted her this little spider pendent. Inside I have hot glued four little Neopixels which are wired up to an @adafruit Feather RP2040 (powered by @Raspberry_Pi ) and a small Lipo battery. Wrote some #CircuitPython code to create the rainbow eye effect to keep it fun!
