I was selling these as a build it yourself kit but unfortunately I have run out. You can however build your own with all the information contained within this web page. You can download schematics, parts list and there are a number of games to try out also.

The circuit design is very simple - it uses an 8×8 bi-colour led matrix display, four 74373 tri-state buffer / latches, eight mini push-buttons, a handful of transistors and resistors - and at the heart of it all is the pic16f648a microcontroller with 16 I/O ports and 4k of program memory.

I built a prototype using a breadboard and also made up a dodgy looking controller from vero-board. I then started programming various games and example programs for the system. Then when i was happy that it would make a good kit - I then drew up the PCB design using a great program called diptrace. I then sent off my design to PCBCART and had 50 boards made up.
