Cube Freetronics

A subproject of regaining control of the Freetronics Cube is to treat the Cube as a Leonardo. The Cube could be programmed using ICSP techniques.

Jaycar 4x4x4 RGB cube Duinotech

Here is a link to a page on the Jaycar website that shows the RGB 4x4x4 cube. Dimensions are not clear or obvious and maybe could be inferred from the size of the LEDs :
