Man builds insane 40 watt laser shotgun
22-year-old laser enthusiast Drake Anthony shows off his latest gadget, a homemade laser shotgun. It's made up of 8 parallel 5W laser beams totaling to 40 watts of power. According to Drake, "The parallel beams are manipulated with lenses, sort of like how a choke modifies the spread of a shotgun blast." 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. It's powerful enough to burn through a ping pong ball!
