Ok then .. perhaps we might have students brewing their own computers ..
"A Tiny Computer Attracts a Million Tinkerers"
By John Biggs, www.nytimes.com Jan 30, 2013
Raspberry Pi may sound like the name of a math-based dessert. But it is
actually one of the hottest and cheapest little computers in the world
right now. Almost one million of these $35 machines have shipped since
last February, capturing the imaginations of educators, hobbyists and
tinkerers around the world.
The story of the Raspberry Pi begins in 2006 when Eben Upton and other
faculty members at the University of Cambridge in Britain found that
their incoming computer science students were ill-prepared for a high-
tech education. While many students in the previous decade were
experienced electronics hobbyists by the time they got to college, these
freshmen were little more than skilled Web designers.
Easy-to-use, modern PCs hide most of the nuts and bolts behind a pleasing
interface. Mr. Upton posited that parents did not want their children to
destroy their expensive computers by experimenting with their insides.
But a cheaper machine would be fair game for messing around.
The Raspberry Pi, about 3 inches by 2 inches and less than an inch high,
was intended to replace the expensive computers in school science labs.
For less than the price of a new keyboard, a teacher could plug in the Pi
and connect it to older peripherals that might be lying around. But
because Pi initially ran only Linux, a free operating system popular with
programmers and hobbyists, students would have a learning curve.
The Raspberry Pi Foundation began selling the computers in February of
last year. They soon could not keep them in stock.
We honestly were thinking of this as a 1,000-to-5,000 unit opportunity,
Mr. Upton said. The thing we didnt anticipate was this whole other
market of technically competent adults who wanted to use it. Were
selling to hobbyists.
One Pi owner, Dave Akerman, of Brightwalton, England, even sent a
Raspberry Pi to the upper atmosphere, floating it 40,000 meters up using
a weather balloon. There he was able to take live video, photos and
measurements.
Now every primary school in the world can take pictures from near
space, Mr. Upton said.
You give people access to this tool and they do great things.
Picking up a Raspberry Pi is not as easy as popping into a store. The Pi
is so popular that many distributors are constantly out of stock. It is
also difficult to find them online.
The old phrase selling like hot cakes needs to be updated to selling
like Raspberry Pis, said Limor Fried, founder and engineer at
Adafruit Industries, a distributor of the Pi. Weve sold tens of
thousands in weeks. Ms. Fried is actually using a few Raspberry Pis and
custom software to streamline her receiving and shipping system.
The Pi costs $35, or $25 for an older model, and comes as a bare circuit
board. Leaving the defenseless little thing unclothed is tantamount to Pi
abuse, so you should also pick up a plastic enclosure. Adafruit sells
clear plastic enclosures for $15, and Polycase.com sells a solid, opaque
plastic case for $17.
The Raspberry Pi works best with an HDMI-compatible monitor and USB
keyboard and mouse. It is powered via a standard USB cable just like
the one that charges your phone and it includes an audio-out port for
connecting a set of speakers, plus an RCA jack if you dont have a
digital TV or monitor available.
There is no on-off switch. To turn it off, you simply pull out the power
cable.
The Raspberry Pi will not do much out of the box. Because it has no
onboard storage or operating system, you will need to copy the necessary
software to a high-capacity SD memory card. A four-gigabyte card usually
works well, but you may want more if you plan on loading applications or
games.
There are a number of available operating systems for the Raspberry Pi.
On the official Web site, www.raspberrypi.org, youll find something
under downloads called Raspbian, a Raspberry-flavored version of the
Debian operating system that includes tools for beginners. Raspbian uses
an interface that will be familiar to users of Windows or Linux.
Adafruit has its own version of the Pi operating system called the
Raspberry Pi Education Linux Distro at www.learn.adafruit.com. It comes
with a child-friendly browser.
Also available are programs that you can use to add additional features
to the Raspberry Pi, including Wi-Fi support (an add-on peripheral is
required) and hardware controllers for connecting your Pi to sensors,
motors and more.
Truly adventurous Raspberry Pi fans can even turn the product into a
small home media center. Because the Pi has a powerful graphics chip on
board, users have been able to stream video and photos to their big-
screen TVs using little more than a Pi and a Linux program like RaspbMC
at www.raspbmc.com. This fully-featured media center lets you stream
video from a hard drive on the network and supports AirPlay, Apples
proprietary video and audio streaming system.
Mr. Upton said the plan was to develop the Pis software rather than the
hardware. If you improve the software, everyone can use it, he
said. If you change the hardware, you leave a million buyers behind.
Mr. Upton said he was blown away by the reception the Pi had gotten
online.
Im not aware of a company that has gone from a standing start to a
million in a year, he said. Its quite a wild ride. I dont get a lot
of sleep at the moment.
When asked if he planned to give a Pi to his children, Mr. Upton said he
and his wife, Liz, who works with him on the project, had not had time to
start a family.
Were busy, so were glad we havent had kids yet, he said. Its Pi
and then kids, not kids and then Pi.
