Gesture-controlled music player with a Raspberry Pi inside

Tejas Ozarkar has fashioned this stylish music player from a Raspberry Pi, some perfboard, some sensors and a bit of wiring. The circuit he’s built allows you to increase and decrease the volume (by raising/lowering your hand above an ultrasonic sensor) and select/control a song by moving your hand in front of an IR proximity sensor. He’s written the whole thing up as a tutorial with photographs and diagrams on The case is actually made out of cardboard and sticky-backed paper, which just goes to show you don’t need a 3D-printer or laser cutter to get something that looks pretty good! Take a look at the write-up here. You can see the player and sensors in action below (Caution: Explicit lyrics)
