Gadget Freak Case File #174: Bus Alert

Bus Alert - Dash for the Curb

GF Mike Moody 450px

When is the bus going to get here? Miles Moody is a busy undergraduate engineering student at the University of Florida. He takes the bus to school, but the bus schedule is slightly inconsistent. He hates waiting for it. The city of Gainesville put GPS devices on their buses so riders could track the location of the bus online. Moody created a device with a buzzer that tells him when the bus is almost at his apartment. Now he can dash out just in time - no more waiting.
