As soon as I'm done attempting my paper clock, I'm thinking of illuminating a Hiigaran carrier. I think I've got the wiring and light isolation down, but the batteries and switch placement are giving me trouble. Specifically, I need a switch that protrudes as little as possible and doesn't require much force to throw.
Just use a miniture magnetic reed switch... No hole, you just place a small magnet over it... Radio shack, electronics goldmine, MPJA have them pretty cheap... Many hobby shops carry them in the HO-scale train sections as well...Wolf
