You could even use it to reverse the current to release the magnet (as the description on the McM page about power supplies implies you must).

I haven't used them, but please let us know how it works out!

I know that the Nerds are going to hate me for this, but I think you really need to consider moving to the Albany area. We need you here Jim!

Forgive my ignorance, but do you think I will need to build a custom PCB to reduce the amperage to the system?
