53 LED CUBE Controller
for PIC16F688
http://picprojects.org.uk/projects/lc/
Do a search on YouTube and you'll turn up literally dozens of video clips of LED cubes, small 3x3x3 cubes, bi-colour, RGB and mono cubes, amazing 16 x 16 x 16 RGB cubes. However, very few show you how to make one and provide the firmware.
The cube described on this page uses a 5 x 5 x 5 matrix of single colour LEDs. This is a good size to experiment with as the number of LEDs required at 125 keeps the cost down, doesn't take too long to assemble and just fits onto a eurocard sized PCB. The power requirement is under 1 amp and the use of just one colour keeps both the hardware construction and control software fairly simple.
The project includes a ready to program HEX file with some demo cube animations and also the source code. The firmware implements a simple macro drawing processor command set so if you've got some programming skills you can create your own animations for the cube.
Although the project on this page uses a PCB, the original prototype (see below) was constructed on a prototype pad board so if you're not able to make your own PCB it's still possible to make this project yourself. (we've now had some PCB's manufactured - you can buy one from the on-line shop )
