Using tech developed by Gautier Hattenberger of the French Civil Aviation University (ENAC), the GameBoy is seen here controlling a ARDrone2 from Parrot. Hattenberger works on the Paparazzi Project, an open-source autopilot system intended for inexpensive autonomous aircraft. The Game Boy isn’t directly related to this work—Hattenberger just found an old one at his parents’ house and, according to his blog, “the first thing that came to my mind was: can I fly a drone with this?”
Hattenberger soon figured out the answer was “yes,” with a few simple modifications. Using a GameLink, a Nintendo accessory originally created to allow for head-to-head competition and cooperative play, Hattenberger connected it to an Arduino microcontroller and an FTDI semiconductor. From there, Hattenberger says, “a small program on the ground station converts this into actual commands for the drone.” It’s that easy! He’s released the entiresource code on Github so people use their own Game Boys to start flying.
