In depth: Raspberry Pi, the computer on a stick
Raspberry Pi is a tiny ARM-based single board computer that enables a TV to run Linux and scripting languages such as Python.
The inspiration for Raspberry Pi comes from the pre-PC computers of the 80s, which encouraged people to programme, even when they didn't know they wanted to.
"There is an energy barrier at the start of the learning curve," said Upton. With the Spectrum or the BBC micro, even if you only wanted it to run a game, you turned it on and it immediately said 'BASIC' and you could write
>10 print "Hello world"
>20 goto 10.
A lot of us got sucked in by that and became programmers."
PCs just don't cut the mustard.
The result is a 32-bit ARM11-based computer than needs no supporting PC.
