I've been experimenting with persistence of vision. I though it would be cool to have PacMan or Space Invaders animated on my spinning bike spokes. Here is a shot of my first prototype test that was also the last. I guess I need a better mounting system because the PCB flew off the wheel with enough force to rip the chips out of their sockets. Miraculously, in a room with lots of windows and glass everywhere, no one and nothing was harmed except the prototype. I guess I should have taken some picutures before the test.
