PDA/Radiation Detector

sgpennebaker writes "This article tells of lab rats who've built a cell phone/PDA/GPS device that also lets you surf the web and, oh, yeah, sniff out any dirty bombs that might have gone off in your area. Then you can cancel your meetings, call family and friends and send GPS coordinates to whoever it is that cleans up afterwards. I'm waiting for the next generation; I want one that also tracks hungry, angry bears and emits a loud noise when it senses their proximity."
