Hello, just had an idea bout using a circuit from a old cheap servo to control a regular DC motor. However, i dout that you would want to control a 6v motor with it..... so I was wonding if there is anyway to amplify the circuit w/ additional battery, mayby 12v?

all servos are are a dc motor and the circut :P
with some gearing
-
i cant find it right now, but there are guides on how to take a servo board and add some transistors for a motor controller. but IIRC it's only one directional
-
get a hbridge and it's bi. directional of course :P
-
you mean just use a dual h bridge instead of a servo circuit?

bane
well yea , thats basically whats in the servo

You know i opened up one of my servos a while back and saw something like a long black bar thing with a few pins coming down, is that the bridge?

ye it is the bridge]
but you should just get the L298 motor driver and use that , it also uses PWM
