It is starting to look like the UK designed Raspberry Pi microcomputer, has become a British success story. The computer, which has triggered all sorts of creative single board computing projects continues to sell in far greater quantities than its creators ever imagined. 

Sales of low cost, open source microcomputer have now passed 3.8 million. That is nothing if you compare it to it is impressive for a bare chunk of electronics. The Pi creators only expected to sell 10,000 boards over its entire lifetime. Pi shipped just over a million in its first year on sale, and some two-and-a-half years of sales are evidently continuing to track upwards.

This summer the Foundation released a beefed up version of the model B Pi, called the B+, which keeps the same $35 price tag but improves aspects of the design to support richer use-cases, such as adding in more USB ports and expanding the number of GPIO pins.

Going online you can find tons of different projects to build using the Raspberry Pi, from small school computer projects to full on mini-computers and home automation units.
