Home-made laser rifle laughs at your puny pointer
• http://www.gizmag.com, By Ben CoxworthThe mostly aluminum-bodied 12-lb (5.4-kg) rifle incorporates a 7-watt infrared burning laser, along with a 2-milliwatt red aiming laser. Power comes from an 18-volt rechargeable battery pack converted to run at 12,000 volts, while a 12-volt pump circulates one liter of distilled water to help keep things cool. An LCD screen indicates when the temperature of that water is getting too high (28ºC/82ºF), at which point the gun has to stop shooting things for a while.
