Mini 4x4x4 cube

A mono cube made of 64 charlieplexed 5mm LEDs (4x4x4), completed around the end of April. Constructed by pbrook.

Martyn's desktop cube

An 8x8x8 cube of 10mm RGB LEDs in an acrylic case. Split into four independent boards, each driven by an ATMEGA328 and 3 PWM driver chips.

Connection is over wifi: when at the space it has hostname "cuboid". Talk to it with python cube.py -P cuboid:3000.
