Maker TinkerTurtle, as they’re known on GitHub, has created the motion activated Portal turret of our dreams—and, best of all, it’s Raspberry Pi powered. This project is referred to as the Sentry Picam and it’s totally open source for anyone who wants to make one of their own.
Inside is a Raspberry Pi Zero W which offers both a small form factor as well as wireless support. The unit is fitted with a camera module inside capable of streaming 1080p at 30 fps. The feed can be viewed at any time from a custom web interface.
