Are you a Legend of Zelda fan? Nah. You thought you were, but you haven’t seen Allen Pan’s crib yet. His entire house is ocarina-powered. That’s a true Zelda fan. Your countless hours of devotion suddenly mean nothing. Allen built a Raspberry Pi-based system that can recognize several tunes from the Zelda games, and they each correspond to different actions like unlocking the front door, turning up the thermostat, flipping the lights on, or watering some house plants.
