Guy Dupont, a computer programmer and tinkerer, received a request from a friend to develop pants that send the user a notification when the fly is down. This invention will hopefully save us needless embarrassment when we discover at the end of the day that our pants were open the whole time.
Dupont used hot glue and safety pins to attach a sensor to the fly, which he then wired to a microcontroller in his pocket. If the sensor detects that the fly is open, after a few seconds, the microcontroller pushes a notification to the Pushover app on Dupont's Android phone.
