Inspired by the small portable spiros showcased in this forum. Very simple to make and easy to use. The square mirrors are not ideal, and will be replaced. This technique http://www.metacafe.com/watch/1076186/diy_front_surface_mirror/ works very well. The last pic shows the components for the next version.

I'm using a two motor differential speed control from a cheap R/C airplane, I removed it and the battery(4s NiMH) for clarity.

Very nice! Clean and functional.

How you will control the motors? With potenciometer, PWM...?

I give you a nice ideia... take a look in this link

and use a transistor/FET and conect at 'out' and you have a simple PWM control.
