[Noisebridge-discuss] Homopolar motors using wire, magnetic BB's, and a battery

A couple months ago someone at NB showed me a very lovely demonstration of
a homopolar motor made with just a few components.   There was a AA
battery, a loosely coiled piece of wire, and one or two of those "BB"
shaped chrome high power magnets.

Who built it?  I would like to make one to show folks here in Austin, but I
don't quite remember how it was put together.
