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?
I'd be more concerned about the less-than-elaborate explosives that seem to be the norm in Iraq and Afghanistan. Just make sure that nobody is standing anywhere near that potential suicide bomber when you shoot him with this thing.
Seriously, shoot some UV dyed hot pepper balls into unruly crowds/at people with guns.
It won't kill 'em, but they'd probably wish they were dead (for a while). Then you can use some UV lights to track the ones you hit (where they've been, where they've gone, what they've touched)
