Parts!

I took apart a broken paper shredder and got a bunch of great parts. In particular, I got some awesome plugs that made attaching things to the arduino easier. I've redone the set temp switch using these, and it's much more sturdy.

Here are a bunch of the parts, including a powerful AC motor. Unfortunately it's AC, but it also just runs off wall current. I got a lot of N4007 diodes, which are great for preventing accidental reverse polarization, one of the fastest ways to destroy electronic components.
