In 2014 cube-mania struck the space.

pycubedemo contains driver for the various cube boards, a cube emulator and a repository of demo patterns.

The Cubes

Mini 4x4x4 cube

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

Firmware: charliecube.

Connection is over USB. Talk to it with python cube.py -P /dev/ttyACM0 -s 4.

Blog post with videos.

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.

Firmware and protocol is here.

LED Array

Not a cube at all, 32x8 RGB LEDs in a rectangular array. Made around June.

Über Cube

The big one, about 2 metres on a side. Each pixel is a strip of 6 RGB LEDs inside a pair of nested plastic drinking cups, driven by an ATtiny (one per pixel!).

Firmware: lightcube.

Exhibited at Leeds City Museum on Friday 3rd October as part of Light Night 2014.

Matt talking about the cube and the space: Hackspace Cube.
