Kevin Rye built this Night Light 2.0:
And there it is. Definitely not my best work, but it’ll do. I just wanted to use up that last PCB left over from the Tesseract build. I guess it was better to use the PCB for something rather than have it sitting in a parts drawer.
I imagined the entire cube being lit up, but seeing as the LED board is sitting on top of the ATtiny breakout, only the top half of the cube is illuminated. Not exactly what I had envisioned, but it does give off a nice swirly red and yellow glow.
