Electric Magnetic Wargaming Hex Tiles

I created this to toy around with the idea of being able to add lit tiles (see photos) or motors/servos to my terrain - for that, I require 3 poles (+,-, and Signal) currently this is only tiles that offer a straight connection, but more will come.

For the example photo I soldered a programmable LED into the tile, with the LED facing the ground to diffuse the light a bit.
