Full metal gauntlet, runs on 1x 18650 plus 2x 14500 Li Ion cells. 2 blue lasers on board, 1.2W each, plus 2 4mW for aiming.
Unfortunately, Patrick doesn't offer any schematics or blueprints if you want to build your own, so I'll probably wind up blinding myself in the process. *shaking fist* You did this to me, Patrick! "I'm over here." Oh, VERY FUNNY.
Hit the jump for a video demo of the gauntlet in action.
Thanks to killahertz, who went on and on about how much he loves lasers even though I know for a fact he doesn't own any and is just a poser.
