Want to build your own computer using the super cheap guts provided by Raspberry Pi
but don't know where to start? Ever wanted to work in a customized operating system you know like the back of your hand? You're in luck. Cambridge University
in the UK is offering a series of free courses online that will teach you how to build your own OS for Raspberry Pi from scratch in just 12 (relatively speaking) easy steps.
Finally, all of us computer illiterates who were convinced that even we could design a better OS than Vista
will have a chance to prove it.
