Forgot a plug for Gecko Drives and transformertechnology.com. Everybody has been very helpfull. I blew up a Gecko drive like a firecracker and I also misswired and fried a Breakboard from Bob Campbell. Both companies replaced the components free of charge knowing it was my fault. I'm a mechanical guy, electronics is not my obviously not my forte. The sparkies here at work make fun of me cause I've been known to shock myself.
