This Homemade 40-Watt Laser Shotgun Pops Balloons Real Good


Says the maker, “The massive diode array is powered by a huge lithium polymer battery pack (capable up dumping 250A) and the laser array is regulated by a whopping 24 LM317 drivers.” I hope somebody reading this knows what that means. It sounds important.

Don’t try using the weapon to shoot burglars, though – it’s basically just an amped-up version of using a good magnifying glass and the sun. Still cool, though, and there’s video to prove it. I hear George Lucas watched it and claimed the balloons fired first.
