Flutterby™! : Simple H-bridge

A simple H-Bridge motor driver, saved here for future reference. As soon as I catch up on building these jigs for the sewing machines for Charlene's business I want to build a simple robot. Actually, I'll probably start with a better throttle for my model railroad, probably with some animation controls and a servo driver of some sort for the turntable (perhaps just stepper with a home switch, maybe some sort of optical encoder and a gear motor).
