36v (modified) Razor e300 (stock controller & motor)

This is my razor e300 (version 35) scooter. I added a 12v battery to make it go around 20mph. The controller and motor are both stock parts (24v, unchanged). You can charge it with a 24v charger. Speed is controlled with the two DPDT switches, both allowing a bypass of one battery each, giving the scooter two 24v settings (two different combinations of batteries) and one 36v setting (all three batteries, no bypassing). The scooter MUST be started on a 24v setting. The lights are made to run on ~24v. 36v upgrade cost: ~$50 -solder, wire, tape (thanks RadioShack) Battery: www.radioshack.com DPDT switches: www.radioshack.com

Art-Rov: Motor, Switch, and Battery Test (001)

I am making a telepresence ROV for an independent project to fulfill a studio requirement of my MA in Arts Education. The robot will be a prototype of a project that I will (hopefully) complete for my thesis.
