A stompbox? What’s that, a guitar pedal? No silly, it’s a WWAN (Wireless Wide Area Network) box that picks up data from cellular towers then redistributes it so that you can use it in whichever way you please. A good example is if you had one in a car, you could trace the car and whether it’s moving and track where it’s headed. Making one requires a few parts and some manual labor working and testing, but it pays off. You can now use Google Maps’ Satellite Viewing to track things. It’s got so much potential to be used in good and bad ways.
