Modular control panel using electromagnets?

Pages: (1/6) > >>

Jakobud:

This is probably not a new idea or anything, but has anyone ever attempted to make a modular control panel that used electromagnets to hold the individual panels in place?  Any examples out there?  I've been trying to come up with a good and simple way of doing a 2-Player modular control panel that be easily converted to "expand" or something into enough room for 4 Players...

I'd think the amount of power needed to give an electro-magnet enough power to hold the cp in place would be pretty harsh.  Maybe use electros to throw pins that hold the panel?  Kinda home brew solenoid I guess?

I don't know if it'd work, but you might be able to use the magnets on Featherboards. For example:

As for expandable CPs (not with magnets), there are a few around. Here are a couple examples:

I may be remembering wrong, but I think someone tried regular rare earth magnets with some success.  Some use gravity and align-pins,  A few have utilized heavy-duty velcro.  I use giro-bolts, and I setup a pair of electric screwdrivers as motors to open and close them.  It was a decent setup, but I am building more cabinet to reduce need to interchange-ables.

I like to use the rare earth magnets out of dead hard drives as closures on my CP's.
