As you can see above, I built a photo frame that has a few interesting parts. For one, the software which runs the photo frame, which I explore below, keeps the photos fresh from Instagram and Flickr. It then displays a random photo for a configurable six seconds. Secondly, there is a motion detector, built using a PIR sensor, which only turns the monitor on when somebody walks by.
This photo frame is easy to build, but it does take a bit of know-how. Mainly, you should feel comfortable soldering wires and mounting the screen and Raspberry Pi to a board or other object. The hard part for me was figuring out how to turn the monitor on and off through the command line.
Everything else is gravy, from configuring wifi and autoboot/auto-login on the device to attaching and setting up the motion detecting PIR sensor.
