The guys over at YouTube channel Hacker House have used a Raspberry Pi as the brains behind a motion tracking, nerf gun turret. They’ve published a video which shows you how to build the turret and install the software. There are copious notes attached to the video including a full bill-of-materials. This is a great maker project because it brings together electronics, woodwork, programming and 3D printing! Take a look at the video above and visit YouTube for the notes.
