So I am desigining a table for fun in which the surface will be covered in paired magnets. The magnets will all be carrying a charge, and once the circuit is completed between a pair, a set of a few LEDs will turn on underneath the glass. Special cups will be designed (crappily ) with magnets in the bottom as well, and so when it's set down on the table and connected to the magnets a light will shine underneath the cup.
The magnets will all be carrying the same charge, so if a person happens to put their glass down on mismatched magnets, it should still work (Right? I think so). My question and problem is this:
If the person set their cup down with the magnets touching 2 positive leads, what would happen? The whole thing will probably be running off 12v. I suppose this could be fixed with some spacing of the magnets and such, but if there's a way to make it not a problem, then I'd like to basically cover the entire table with them.
My other problem is this: What about spills? Will a spill of water over the magnets, assuming a great seal between the glass and magnets, short out the system? I don't expect to be spilling, but I want to plan for the worst.
Any suggestions for this project would be great, I just came up with it a few minutes ago.
Thanks!
