This guy built his own highly-dangerous 320mA – 465mW phaser (video below). I have food poisoning, so I can’t be arsed to figure out those instructions right now, but I will say it looks pretty easy to build considering what it can do. Sure, you may accidentally start a fire or aim it at reflective surface and blind yourself, but how cool will you be at the assisted living facility when you tell everyone you’re blind because you shot yourself with a phaser? Show those macular degeneration suckas what’s what. Oh, you have a serious disease? I have a laser gun. Pew pew.
