I see that,
"Cambridge University is now offering a free 12-segment course that will guide you through building an OS from scratch for the tiny Raspberry Pi development board–learn the ins and outs of basic OS design on the cheap.
You’ll need a Raspberry Pi board, a computer running Windows, OS X, or Linux, and an SD card, as well as a small amount of free software. The 12-part tutorial starts you off with basic OS theory and then walks you through basic control of the board, graphics manipulation, and, finally, creating a command line interface for your new operating system."
Google "Baking Pi – Operating Systems Development"
I don't think you get a degree at the end of the course though!!
After completing the course can you state "I went to Cambridge"??
