"Got an old DVD burner lying around? A mini Mag-lite flashlight? With a few dollars worth of components and some basic soldering skills you can create a dangerous (if not lethal) burning laser pointer. This one won't just put a red dot on the wall - it'll leave a scorch mark."
I SOOOO want to try this! Next time someone tailgates me when I'm riding....oh boy....*mops busts out light saber death ray thingy*
