This has to be, hands down, by far, the best DIY. What can be better than you playing video games. And no, Kinect is NOT a video game. I am talking about the 90’s. Yes, so going back, what can be better? Making your own video games! You need Raspberry Pi, CPC Telera and a little knowledge of C.CPCTelera is a development framework for creating CPC games and content. It includes support for all the needed libraries, like audio, graphics, strings etc.  It is multiplatform and can be run on Windows, Arch, Ubuntu, Raspbian Linux and other OS. You can get the complete code from GitHub. Once you have everything up and running, you can browse through the files, play around with video and audio authoring.
