Introduction• The Raspberry Pi is a credit-card sized

computer that plugs into your TV and a keyboard, which can be used for many of the things that your average desktop does - spreadsheets, word-processing, games and it also plays high-definition video.

• The Raspberry Pi charitable foundation wants to see the device being used by kids all over the world to learn programming and electronics.

Background•6+ years

•Pi Foundation

•Cambridge University

•Programmers

•Education

•Industry support

Why

What made computers accessible and fun

What are the barriers that exist today

Computing in Schools

The Raspberry Pi charitable foundation is working with partners to get software materials developed, as well as with the open source community.

The foundation is also working with partners to use it as a teaching platform for other subjects, including design, art, languages and maths.

USP ?

•Model A - $ 25

•Model B - $ 35

•Why so cheap ?

•SoC - System on a chip, a computer on a single low voltage chip

•Linux OS

Operating System•Linux on a bootable SD card

•Fedora•Debian

•ArchLinux

Other pre-rolled projects exist like XMBC Media Center

Programming

•By default, supporting Python as the educational language.

• Any language which will compile for ARMv6 can be used with the Raspberry Pi, though; so you’re not limited to using Python.

•For primary age SCRATCH game maker is bundled

Scratch

scratch is free from MIT .. thanks MIT !

Scratch

Your own pocket laboratory

Tinkering

•GPIO pins if you’re after an interesting electronics project.

•Gertboard - A GPIO expansion board from the foundation for electronics projects

•USB Devices / Ethernet / Hubs / AV out

•Can be powered by 4 x AA batteries ...
