Raspberry Pi, whose popular minicomputers are sold around the world, has come a long way since its co-founder Jack Lang had to store some of the first batch of single-board devices in his garage more than a decade ago.
What started out as a project to reverse the decline in computer science applications at Cambridge University went on to inspire a generation of child programmers by offering them an affordable $35 (£28) minicomputer. Now the company is preparing to list on the London Stock Exchange.
