Thanks for the welcome, Pete! I came across this thread a week or two ago and I'm going to start putting my own little driver and circuit together starting today or tomorrow. The only thing I need to get before I can start is a piece of steel for the blade. The guys and gals at the local hardware store couldn't seem to figure out where they keep their steel stock...

Make sure that the 22uF, 100uF, and 220uF caps you get are electrolytic. I picked up a 2N5457 transistor to use for my circuit, so we'll see how that turns out. Here is how the pins correspond: Also, here is some info from the LM386 datasheet about the gain:
