Question 949

Is there a homing device small enough to fit onto or inside a pc laptop? How does a homing device work?
There are homing devices small enough to fit on bugs, so there should be no problem fitting one on or into a laptop. A homing device is simply a radio transmitter and, while it has recently become possible to build a homing device that actually knows where it is and can tell you via its transmission, the techniques involved in locating most normal homing devices are those of trying to find the source of a radio transmission. Using directional receiving antennas and studying the transmission from several locations, you can figure out where the transmission is coming from.
