I paid a visit to RadioShack yesterday. There are not many truly useful things there. I was able to pick up a rectifier, and some magnets, but the magnets are little 1" by 3/4" ceramic ones and probably won't do much.
I taped the magnets around a wooden circle and connected that to an electric drill. I then spun that right next to the entire coil of mag wire that Nick gave me. (connected both ends to the multimeter) It didn't work though... I tried connecting it through the rectifier but that didn't work either. It would be good to get wire of a smaller gauge (thicker wire) and some neodymium magnets. But all that (especially magnets) costs money!
