I know the simple answer put my hand in my pocket and shell out loads of coin and buy all the kit: Speed Controllers, Mixers and Interfaces. But what I would like to do is build it myself. I`m only building a prototype first attempt Robot at the moment, to satisfy my son!!! Problem? I`ve got a RC JR Radio kit Tx & Rx and I`ve got two 12v Motors. I`m looking for schematics for On/Off/Directional Speed Controllers and an interface to link this to the Rx output that would normally go to the servo`s Any help would be appreciated I`ve got a couple of Speed Control circuits, on which requires two Digital input for On/Off and Forward/Reverse and a Pot for Speed. The other circuit is a Back EMF PM Speed Control and a PWM Speed Control. "The more I try tiddly pom, tiddly pom" bill_harvey@LineOne.net
