Cool solar tracker

Supposedly with only $10 in parts, thought those cells maybe a bit more than that (unless he got them in bulk).  Basically you use the small cells to determine if they are in sun, if not, then its OK in that direction.  Else need to move it to cover.  In this case each panel moves the motor when powered.
