This one is the most similar to what i am building, except that mine is a single phase (as opposed to 3), and i'm only using repulsing magnets.
Also, if you're new to home experiments of this type, here are a few sites so you can get the necessary materials.
I'm sure people will add to the list as time goes on so feel free. I also recommend a Dremel, as it has proven itself time and again in my garage.
