RASPBERRY PI HISTORY
 Around 2005 Eben Upton was Director of Studies in
Computer Science at Cambridge.
 Incoming students had relatively few programming
and/or hardware skills vs “the old days”, creating
vision of “something like the BBC Computer, but
running a modern language like Python.”
 The name “Raspberry Pi” is a combination of “a fruit
name” and a play on “Python”.
 Developed in UK by Raspberry-pi foundation in 2009.
supported by “University of Cambridge Computer
laboratory & Broadcom”
 Basic aim is to promote the study of basic computer
science in schools and to develop interest among kids
and adults 5

PREPARING RASPBERRY PI FOR USE
Preparing SD Card
An Class 4 SD card with 4GB size is recommended
 Download the Raspbian Image from Raspberry Pi
downloads page: http://raspberrypi.org/downloads
 Unzip the downloaded file - will get an .img file
 This .img file can only be written to your SD card by
special disk imaging software,
 Download the Win32DiskImager (for windows OS)
Software from: https://launchpad.net/win32-image-
writer/+download

PREPARING RASPBERRY PI FOR USE
 When we double click
Win32DiskImager.exe
(on windows OS), we are
asked for image file.
 Locate the image file
downloaded and click
write button.
 Use this card to boot the
Raspberry Pi

On first boot you will come to
the Raspi-config window
 Change_timezone setting
 Select the second choice:
expand_rootfs
and say ‘yes’ to a reboot
 The Raspberry Pi will reboot
and you will see raspberry pi
