James writes "Rostislav Persion from Voltage Labs has successfully constructed a HERF gun (a device like EMP but directional) in his home that is capable of stalling cars at a distance and crashing computers as well. He has videos of the device in action as it lights up LED's at a distance and triggers motion detectors. Theres also a bunch of other security stuff and science stuff which is quite interesting and controversial, such as cell phone tracking, mood altering audio signals, gyro guns, and other things of this nature. The site owner was also featured in US News Magazine and MTV for some of his work."
