Gauss' GP-219 electromagnetic pistol fires steel projectiles silently

Sure, mechanical sentries and AirSoft turrets are novel, but there's nothing like whipping out an electromagnetic pistol to show folks you mean business. The Gauss GP-219 looks like it came straight from level 5 of Duke Nukem 3D, and rocks a PIC microcontroller, dual coils with "precision pulsing" to fire steel projectiles, twin infrared sensors to assist in positioning, and even a laser sight to keep your enemies pegged. Powered by an NiCd battery pack, this bad boy also features a bar display to track "capacitor bank charge progress," battery and fault LED indicators, and is "completely silent" when fired. The wildest part about this science-fiction dream come true is how effective it actually is, so be sure to click on for a few more pictures, and hit the read links for all the nitty gritty and even a few live action videos.
