I don't know much about h-bridges but there are many posts on this forum about h-bridges and from what i can gather the h-bridge can run a dc motor forwards and backwards and i can see no reason why it should not work for your task. The L293D is very commonly used for driving stepper motors and dc motors.
i suppose it depends upon the specifications of your motor,
DC operating voltage?
current draw?
i'm no expert on h-bridges.
hope this helps
don't forget a reverse biased diode across the windings to prevent counter electro motive force.
rancid, you need to tell us what current your motor will pull. if it's a small motor, I'd bet the current level will be fairly small and thus the L293D will work just fine. You will only need 1/2 of it, by the way.
It's got to have been an absolutely tiny motor?, an LM324 can provide hardly any current at all? - I'm doubtful there's a motor that low power? (that could move anything worthwhile).

I built it and it worked. The motor was about 3cm in diameter, don't remember the voltage, probably 6 volts because it was powered by batteries. The dish antenna was to float on the water, the servo kept it ponted at the satellite.
i preferably wanted the most simple H-Bridge possible thanks, it only needs to move a very small and light piece of wood that will be on wheels or a rack.
