Raspberry Pi
Yes, I am one of the several million people who do not actually belong to the intended target audience of this remarkable little device... Yet I hope that it will motivate many young people to hack themselves into the bare bones of computer technology, just as I was once fascinated (and still am) by computers you actually had to learn to program in order to do something useful with.
In this section of my homepage I will present some -- more or less elaborate -- Raspberry Pi projects of mine.
