If you've ever watched battle bots or robot wars on the television, then you'll understand what this is. I'm using diodes and relays to use a small 9 volt rc circuit to power a large DC motor with two 12 VDC batteries.
Now, the power coming out of the PFM circuit (remote control, PFM meaning Pure F**king Magic) is only two volts, ant I need more power to actually work the relays. The problem is I can't add more power to the PFM circuit because I might fry it since it's little and cheap. I remember from my "tech core" class back at my old training command (I'm a radar tech in the Navy) that transistors were a great way to amplify power, but it's been quite a while. If anyone has any advice I'd be most greatful.
