10/9: Wheel ad

Here is another photo off of the very annoying inventor's site. There is a wierd double exposure of the thing behind the driver's head, probably caused by the photographer's panning. It looks like the resolution of (number of) the LED's does not have to be that great, but it is the timing of the flashes that matters because of high rotational speed. This allows one LED to cover more area in less time. I just want to know how you design a reliable circuit that spins that fast in such a harsh environment.

There was an article on /. about spinning LED clocks like this.
