Here is a gadget that is suppose to be intended for playing pranks at the office. The Phantom Keystroker. It looks like an ordinary circuit board, but is actually filled with a lot of unwanted items that will drive your office colleages crazy. “Simply discreetly attach the Phantom Keystroker to any extra USB port on your victim’s computer, no drivers needed. The Keystroker emulates a keyboard and mouse and periodically makes random mouse movements and types out odd garbage text and phrases. A simple jumper setting allows you to choose between either keyboard garbage typing, annoying mouse movements or both. An adjustment pot sets the duration between “events”. Use it at your own risk. We are not responsible for someone whipping your butt.
