I’ve created a very simple Raspberry Pi project that I use to let my kid know if its daytime or nighttime. When I say goodnight and leave my kids bedroom, I trigger a simple script on my Raspberry Pi with a 7″ touchscreen attached. The screen will display a daytime image for a few minutes, before switching to a nighttime image. The nighttime image is an indication for my kid to put down her toys and go to bed.

Over at github I’ve documented the steps to get the project up and running.
