I saw this on Hackaday tonight.
This guy devised a way to build a video game using persistence of vision, LEDs, some PICs, and a motor to build a game system. He based his creation on the scanning clock built by Bob Blick – Blick is a great guy, I’ve built a few of his speed controllers and they work very well.
Anyway, he mounted the motor and all the hardware on the spinning arm to balance it all out and used ball bearings as communicators for the ground, power and hand held controller.
So far he can play Pong and a Tetris like game as well as display an analog clock and input from an RS-232 port. Best of all, he has schematics and code is you want to build your own. Any bets that we will be seeing this in an up coming issue of MAKE?
