About 6 months ago I bought the Joey Hurdy LED 3x3x3 led Cube for the Arduino platform. While soldering it together wasn't easy, once I had the basics of the LED placement down it went pretty quickly. Makershed.com has it on sale right now for under $10
Just recently I got a pcDuino, which is a Linux based Arduino platform with the Inputs and Outputs of an Arduino UNO. So the thought occurred to me, why not see if they work together.
So, I grabbed the code, which can be downloaded here:
Copied it to an USB flash drive and then loaded it in the pcDuino's Arduino IDE, which is running 1.5.3 beta for Linux.
