Upton, the founder and chief executive of the 10-employee foundation in Cambridge, England, says he grew convinced that more kids needed introductory programming lessons (or, in some cases, remedial ones) while he was running the computer science department at St. John’s College at Cambridge. While interviewing high school students who had applied to the school, he says, he often found them less prepared in the computer science field than he had expected. “We were finding we had to teach people things we assumed they already knew,” says Upton.
The professor started developing his single-board computer in 2006 and released the first version in 2012 after six years of prototyping. B+, the single-board computer’s third commercial version, went on sale last month for $35. Customers can purchase the device from the Raspberry Pi website or such product sites as Adafruit.
