Oh, sorry! See this post:

Um, just to make sure I've been clear about this, this apparatus didn't use all
Lego. The electromagnet, the feedback circuit, the control circuit and the
power supply were made with non-Lego parts. It might be possible to use an RCX
for the control circuit, but the robotics guys seem to think that it wouldn't
work.
I wish Lego would make a Mindstorms Experimentor set, complete with an
electromagnet, stuff like that. Students could measure G, make things
levitate, etc.
Glad you liked the set up!
Chris
