Using the HD as a speaker was surprisingly easy. I just unplugged the speakers from my stereo, and hooked two wires from the stereo to the HD coil. Then I turned up the volume to max. Check my web page for more info on the project.

Why don't you just use a mirror galvanometer? That's what they are for! :)
