I would like to reuse my old satellite actuaters, and repurpose them for use as a/an sun tracker for a solar panel project I have in mind. I am in need of a descent way to "track" the sun to obtain, & then maintain the optimum exposure to the sun, for optimum output from my panels. I have 3 actuaters at my disposal, but I figure I would really only need 2. Now Just need the reliable tracker device/circuitry.
