Tell us about yourself!
We actually get our rods from old wire shelves and old CD case holders.Thrift stores are full of them! A screwdriver is a good idea too!

I guess with more windings, thicker wire, a more powerful magnet, and faster/ more powerful spin, you might be able to make something useful but there really are much better ways. I don't know much about the AC side of things though, I am sure getting your generator to put out the 60 hertz and everything else would require more technical components.
No, the generator is the power supply. you could maybe use diodes to create a diode bridge to output a straight DC signal.
