Come on!!!! You know you want one! Here’s my thinking on this project – build this, figure how to link it to your PC, and put up a couple around your cubicle at work. Suddenly, no one can surprise you by sneaking up to your cube because they are too short to see and detect over the wall. The Instructables guide mentions hooking it up to a sound playback device, but I think if you could hook it up via USB and write a driver to make a pop-up onscreen whenever the detector activates, you’d have a nearly perfect boss-detection-system (BDS) for work use.
