Raspberry Pi: Tiny, Cheap, Powerful

The Raspberry Pi is a $25 or $35 computer that is roughly the size of an Altoids tin. It may or may not end up being fully open hardware.

Here are some more details from David Braben.

A neat feature is that it is “stateless” which means, in a practical sense, even after you’ve used your Raspberry Pi for a while, the SD card is the only thing that distinguishes it from any other Raspberry Pi. So, if something goes wrong with it, you could just move the SD card and all the peripherals to another one and get right back to work.

Reaction from the community:

  • One of perhaps the most exciting things about Raspberry Pi is, as Jeremy Ruston had previously noted, how it nudges you towards hardware development.
  •  It was suggested that a standard for expansion boards was much needed…A concern was also raised that in the absence of a standard at present some may be wary of designing add-on boards should one subsequently be published.
  •  The potential for using Raspberry Pi as the embedded controller in a RepRap 3D printer was discussed next, noting how the powerful ARM processor would enable it to do things that would just not be possible with a small microcontroller.
  • …a discussion was centred around the idea of a Raspberry Pi emulator which would not only be capable of booting Linux, but that would emulate the board’s GPIO etc

Wanna see the schematics?
