Since the $35 credit card-size Raspberry Pi went on sale last February, hackers have made it into a game console to a Linux laptop to a supercomputer. And an estimated 1 million PC hobbyists have snatched one up. The U.K.-based Raspberry Pi Foundation says it's become a phenomenon. "There's no sign of a slowdown in demand," says Mike Buffham, of Premier Farnell, one of two distributors.
The Pi's aim was to inspire kids to write code and build computers, but they're also a hit with adults. Its core is a stripped-down Linux PC with a tiny circuit board, an ARM-based CPU, a graphics processor, and several pins and ports. And from that blank circuit board of a canvas, the creativity flows.
