Okay, I've done a design for what I'm going to use for MicroSeeker.

Note that the thrusters in MicroSeeker are only 1" in diameter, but this
should hopefully give people some idea of what I think will work.

I'm getting my rare-earth magnets at Radio Shack, but of course I can use
little tiny ones... I'm not sure what size I will need to do the proper
torque transfer, but I'll find that out when I build it :-)

Later,
Jon
