✦ Synopsis

Raspberry Pi is a UK Non Profit with the goal of creating a new generation of computer programmers. Observing how the UK Tech Industry was kickstarted by the availability in the 1980s of relatively cheap, very programmable computers such as the ZX81, the Commodore and the BBC Micro, the Raspberry Pi Foundation designed a �15/$25 computer which encourages the user to play and to learn. Although intended for schools, it has also been adopted by hackers and geeks, and a whole ecosystem of software and hardware is being built around the Pi. With a million boards now sold, the goal of the Foundation is well underway.
