A cop in every car

[Michael] designed this display board to mimic the appearance of a police car pulling you over. It resides in the rear window of his car (facing forward) as the controller board measures the speed of the vehicle. An Arduino grabs NMEA data from a GPS module and compares it with a table of speed limits. If you are speeding, based on your current location, the reds and blues flash as if you’re getting pulled over. The thrill of getting busted for a lead foot doesn’t sound like much fun to us but to each his own.

Incidentally, [Michael] is using the EM406 GPS module, the same one as the Frustromantic Box used.
