Digital Handgun Won't Fire Without Custom Wristwatch
Another goody from Wired's Danger Room (previous post, the oh so very cute Koosh Bullet). This time the weapon on display is the amazingly "smart" handgun: a gun that won't shoot unless you're wearing the right watch.
"German firm Armatix has an electronic safety that automatically disables the pistol when it's not within a few inches of a custom wristwatch. The watch sends a wireless arming signal to the gun. If the gun is picking up a signal from the watch, a green LED on the back lights up. Try squeezing the handle without wearing the watch, and you will see a red warning light.
Anyone can pick up a limited edition version of the pistol for about 7,000 euro, which is pretty steep for a .22cal plinker. They start shipping next month."
