Mavelous, a new open-source software project, lets users control homemade UAVs via their iPad, iPhone, or Android device. Piloting a drone is as simple as tapping a spot on the map.

In this instance, though, the QR code converts your cell phone into a remote control for the AR Drone that suddenly appears on your screen.

The hacking drone called WASP now includes GSM-eavesdropping capabilities.
