Shooting from the Wrist

摘要

Last octorer, after hurting his knee playing hockey, Patrick Priebe was holed up in his apartment near Cologne Germany, with nothing to do. He was sitting at his computer, staring at his keyboard, when the "Y" key caught his eye. Priebe didn't see a letter. To him, it looked like a crossbow. Immediately he knew what his next project would be. For years, the German lab technician had built laser weapons, including a working Iron Man-style palm-fired blue-diode laser. After all those futuristic gadgets, he wanted to make a completely mechanical contraption. Priebe doesn't draw up designs for his projects; he just starts tinkering. In his home shop, he cut some bars from an aluminum sheet and fastened together a Y-shaped frame that fit perfectly over the back of his hand.
