YOU CAN CARRY a taser aboard an aircraft if you have a SonyEricsson K800i cameraphone in your pocket. The K800i's Xenon Flash circuit pumps out nearly 300 volts and that's enough to reach out and jolt someone but not incapacitate them. Creating a K800i taser is quick and easy for anyone used to DIY electronic kits. You open the phone, snip a few wires and connect them to the xenon flash circuit. This means that whenever you activate the flash camera mode, you send 300v across the taser probes on the back of the camera. This taser burst stings worse than a flu shot but it is not lethal. So before you dump your K800i into the recycle bin, consider its second life as a taser cameraphone.
