Laser Spirograph Using arduino

I was fascinated with Quackmaster Dan's "Four Motor Laser Spirograph" so I decided to build one. The pictures represent about a year and a half of procrastination, and late nights, all in all it probably took me about 80hr. to build as I had to go through a couple revisions of the electrical system, and it was totally worth it.

If you have any questions about components or fabrication, leave them in the comments and I will gladly answer.

The reason I didn't post an instructable is because the basic theory of operation is no different that the other spirograph instructables. The only difference with mine is that I map the values from the potentiometers to the motor speeds using an arduino microcontroller.

As for a list of components here you go:

4x 1k Potentiometers
1x Arduino
1x Motor Shield
4x Motors (I chose 12V DC Fan motors because they were cheap and already had mounting holes.
1x laser (as bright as you want)
4x Round mirrors (Check hobby and craft stores)
