This video demonstrates the TinyTracker HD solar tracker control unit from Home CSP (http://homecsp.com/store/index.php?id_product=41&controller=product) operating with a 9.6 V cordless drill motor and battery. The tracking controller, relay booster module, battery, battery level meter, drill motor and gear boxes are contained in a 2" ABS pipe. 

A matching gearbox containing two extra sets of 5:1 ratio planetary gears was stacked on top of the original gearbox effectively reducing the 10,000 RPM  down to 16 RPM at the chain drive sprocket.

A relay booster module from SBE Solar Technologies (http://www.sbesolartech.com/relaymodules.html) was used to deal with the high amperage requirements of the cordless drill motor (up to 30 amps at stall) which would otherwise have burned out the TinyTracker HD control unit.
