The Raspberry Pi has many uses, but one you may or may not have thought of is as a remote Internet-connected camera interface. With a little work, you can make it not only display real-time images, but turn them into a side-by-side 3D stream, appropriate for viewing on 3D goggles or Google Cardboard.
University of Technology, Sydney graduate, web developer, and assorted technology hacker Patrick Catanzariti decided to take this on as his first project with his Pi. He had experience with microcontrollers like the Arduino, but, as he puts it, “Video streams aren’t really suited to a microcontroller.”
This build actually looks much easier than you might suspect and is well-documented in the above link. He recommends a WiFi adapter so you can transport this setup, and used the Raspberry Pi camera that simply plugs into the flex cable connector. Once plugged in, he set up a program called RPi Cam Web Interface, and with a few terminal commands, set up the camera for use on his local network.
