What is the Raspberry Pi?
The Raspberry Pi is a $35 mini computer, which was created for educational purposes but was also received with enthusiasm by electronics hobbyists and makers.
HDMI connector (digital video out)
camera module connector
10/100M ethernet connector
4x USB2.0 ports
General Purpose Input/Output (GPIO) pins
DSI display connector
Broadcom System-on-a-Chip (SOC):
CPU + GPU:
900MHz quad-core ARM Cortex-A7 CPU
VideoCore IV 3D graphics core
1 GB SDRAM
microSD card slot
But basically, it boils down to this...
Hardware features & performance
RPi 1 works passably as a desktop computer, "considering"
RPI 2 works passably as a desktop computer
plays full HD videos with GPU support
camera module has 5 Mpixel resolution, shoots full HD video or VGA @ 90 fps
works nicely as a media center
can control elaborate electronic circuits via GPIO
can be used "headless" (without keyboard, mouse and monitor
very low power consumption, typically 2-3 W
* not a full Windows 10, e.g. no GUI!
All the usual Linux stuff, with special emphasis on programming and education.
The Raspberry Pi Foundation is a UK charity founded in 2009 to promote the study of basic computer science in schools.
The Foundation is supported by the University of Cambridge Computer Laboratory and Broadcom. Its aim is to "promote the study of computer science and related topics, especially at school level, and to put the fun back into learning computing."
In 2011, the Raspberry Pi Foundation developed a single-board computer named the Raspberry Pi.
The Foundation started accepting orders on 29 February 2012.
The Foundation thought 10k units was a good amount to start with;
Their website was immediately overloaded;
They sold 100k within hours...
Until February 2015 (3 years from start) 5 million Pis were sold
The Raspberry Pi was by not the first of its kind; but by the low price ($35) made it accessible to many
Buyers included teachers, schools as well as makers and hobbyists
Manufacturing soon moved to a Sony factory in Wales
Demand for the RPi continues to be high
The Raspberry Pi Foundation is a non-profit organization
One of its goals is to raise the level of computer literacy of children (and adults!)
They maintain a blog, a forum and a host of teaching resources to facilitate teaching, learning and making with the Raspberry Pi.
Engaging kids in programming is easier if there is immediate, tangible feedback rather than abstract lines on a screen
Physical feedback includes real world effects: sounds, light, moving a robot...
Phyical computing means creating programs which interact with the physical world
The low price point of the RPi made it affordable to many and its versatility lends itself to many applications.
The number of users has grown quickly and now its difficult to think of doing something with the RPi that someone else hasn't done before...
Lots of documentation
and friendly help!
The official RPi magazine
Started out as a community effort
Now published by the Raspberry Pi Foundation
Edited by volunteers
Articles are contributed by the community
Available as a free-to-download pdf, but also can be purchased as an ink-on-paper magazine
Issue #40 came out in December 2015
The first computer magazine which
actually comes with a free computer! (a $5 value)
Some of the heroes

Raspberry Jams are events organised by the community to share knowledge, learn new things, and meet other Pi enthusiasts. Programs usually include a mixture of practical workshops, technical talks, show-and-tell and a popular marketplace.
Pi Wars is a challenge-based robotics competition in which Raspberry Pi-controlled robots are created by teams and then compete in various challenges to earn points.
Free training courses for teachers and educators
Unfortunately, most of these are in the UK...
Pi suppliers and accessories
Time lapse photo rig
Mechanized chicken coop door
Networked media player
