Paintball Sticky Sensors
Eddy_D writes "The EETimes has a story about a group of undergraduate students at the University of Florida (Gainesville) that have developed a sticky sensor, fired from a paintball gun, to sense explosive compounds in suspect objects at a distance. The project is funded by Lockheed Martin (Missiles and Fire Control group), who is rushing to deploy this new technology to soldiers in the field in Iraq and Afghanistan."
So, basically, we can deploy a shitload of these into Iraq to find the WMD's...
All jokes aside, it sounds cool, you could use any kind of sensor with it. How about one with a frequency counter?
