[don] built this RC car using two $10 cordless screwdrivers and a few parts from his bin. He cracked open the screwdrivers and relocated the switches to the outside. These micro-switches are activated using some servos and radio gear he had laying around. For as little time as it took to build, the car seems pretty serviceable. He mounted a camera to a turning servo so he could see the car’s perspective. The camera looks into the turn so it’s easier to drive the car than if it was in a fixed position.
