The buzz around Raspberry Pi started two years ago when we were offered the prospect of a tiny Linux computer (http://www.raspberrypi.org/about) that would cost around £30. That’s a trivial amount of money for an interesting new gadget so I slapped in my order with RS Components (http://raspberrypi.rsdelivers.com/default.aspx?cl=1) , and sat back to wait. Some time later I received my Raspberry Pi model B and was amazed when I opened the box.
