I used Jeff Haas's instructables hack for the talking skull by gemmy. The small circuit was a pretty easy build and works well. Many thanks to Jeff and the good folks who put that together. My problem is, my skull has the moving eyes controlled by a separate DC motor. The eyes turn one direction and stop, because the polarity needs reversed. I've read about guys using a DPDT relay but that would also require additional circuitry to flip flop the voltage. Has anyone else attempted this or have a circuit that could accomplish this task?

Next year I plan on going to servos and a micro-controller, but it's getting late in the game to start over for this years haunt. Any help is appreciated.
