For several years now, I've wanted to duplicate the original vector-display Atari Asteroids on the Gameduino. There's something about the this early monochrome vector game that I find very pleasing. This Summer finishing Dazzler presented the perfect excuse. Read the full update.

I'm dedicated to building useful hardware and software, particularly where embedded systems meet graphics and imaging. Probably my best known public projects are the Gameduino series of game accessory boards, and the J1 CPU. I have benefited immensely from Open Source hardware and software, so I try to open source as much as I can.
