so so yeah so I'm here to talk about
this this is a Raspberry Pi does anyone
of the audience have a Raspberry Pi
that's awesome
so I'm still in I'm still kind of
mentally in this in this place where
this time a year ago I had a spreadsheet
on my computer that told me where every
Raspberry Pi in the world was so it's
kind of it's just it's great you know
several of you here I don't know so
that's that's really encouraging
that's the Raspberry Pi for those those
of you who haven't seen raspberry PI's I
have two are there any personal injury
lawyers in the room okay in that case
okay these do need these do need I'm
afraid to come back because they are the
door they are the door prizes but I'll
bang that over there cool
feel free to unbox it and take a take a
look at it so you have some idea what
I'm talking about
okay I guess today I thought my talk
title is inspiring future generations
with open hardware I guess what I wanted
to do is I'm going to talk a little bit
about the Raspberry Pi why a group of us
thought that there was a problem and why
we thought we could solve it with
something to look like that I wanted to
make a just a few a few general comments
I guess about the open bit of that title
there and maybe some risks that some of
us in the foundation have there were
some concerns that we have about the
risk of an increasing level of closure
in the hardware that we're that we're
coming to use to do a bit about the
problem give you a little bit of the the
story of Raspberry Pi how we got from
from thinking there was a problem and
that's now quite a long time ago I'm
aware I've been giving variants on this
talk for so long that all of my I say
it's been a six-year journey it's really
now getting on towards the point where
has been a seven-year journey so I'll
talk a little bit about some of the
things that have happened at about where
we've got to now and then I was going to
conclude I don't really have any slides
my talk that I was going to conclude
just with a few pictures that I think
illustrate we've been in the wild for
six or seven months now I have some I
have some pictures which I which I think
illustrates some of the uses that people
have been putting PI T so as James
mentioned pi PI for me is something that
comes out of the end of my time as a PhD
student at the University of Cambridge I
was I came up to I
came over to Cambridge in 1996 as an
undergraduate and at that point we had a
a very healthy typical Cambridge
application ratio yeah we had a six to
one application application ratio so we
could pick or we could pick very very
carefully and we were we were
overwhelmed
not just with candidates but with
incredibly high quality candidates so of
the people we let in the door and
probably a lot of the people we rejected
we could rely on all of those people
having you know having been programming
having maybe even as much as a decade of
experience of programming computers I
came in the door with a couple of
knowing a couple of kinds of assembly
language and that was a pretty typical
skill set and in fact the problem that
the faculty had at that point was not so
much teaching not so much kind of
bringing people up to speed as
convincing these people who came in the
door that we didn't know everything now
fortunately we had a thing called we had
a thing called functional programming
that we would subject our first years to
we could you know hit so these in
obviously accomplished young people
would come in the door we'd hit them
over the head with standard ml for eight
weeks and then when they would come up
on the floor at the end of that we could
then start to build them up and of
course being able to have such a fast
start is enormously important set in the
Cambridge system because we have over a
3-year course only 60 weeks of contact
time to turn somebody from the six
former into somebody who can start a PhD
so being able to make a really fast
start was extremely useful and to some
extent the department have got very fat
and happy on this stream of this stream
of very talented people now by the time
I was finishing I was finishing my PhD
in 2005 and I took a job as a director
of studies now people have been through
the Cambridge system the world will know
the job of the director of studies is to
organize the undergraduate of teaching
and is organized undergraduate teaching
and also to organize the supply of the
undergraduates
so to go out to schools and evangelize
whatever subject it is you're you're
pushing and then to interview people in
to interview people who come in the door
in December and try and decide who to
who to take on um and it was kind of a
little bit disappointing because what I
found was over those ten years between
my arriving as an undergraduate
am I starting to interview new
undergraduates the number of people
applying to read computer science at
Cambridge had high
we've gone from maybe 500 applicants for
80 or 90 places to to maybe 250 so
that's still it that's still you know
good a good a good cover ratio but it's
nothing like what we were used to but
more alarming for us the average skill
set of the people coming in the inn
coming in the door had changed from a
bunch of assembly language and graphics
hacking to maybe having done some HTML
maybe a little bit of web programming if
we were lucky now there's nothing wrong
with that and these are still extremely
bright people we're still able to fill
our fill our lecture halls with 80 or 90
very bright young people but the problem
was that we had to spend a lot of time
in our first year bringing people up to
a level of skill that we'd previously
been able to assume and this was
obviously extremely worrying for the
university anything that's worrying in
that way for a university is probably
going to be worrying for industry
shortly thereafter you know if people if
we if people stopped coming into into
university in severe number in your X
and your X plus 3 or X plus 4 they're
going to stop turning up at in industry
subsequently I've ended up in industry
and I have this it's just subtly
disquieting to look around at the number
of people in their late 20s and their
30s and then the number of people in
their early 20s increasingly for us I
worked for coming to call Broadcom
increasingly for us
recruitment means poaching away mid
mid-career people from other companies
rather than being able to bring in as
many graduate hires as we'd like to be
able to so a group of us in academia
were worried about this a group of
people in the Cambridge the Cambridge
cluster were worried about this and we
started to wonder why this had happened
to us and B whether there was anything
we could do to try and fix the problem
and the hypothesis we came up with and
for us it really still is a hypothesis
this is still a working hypothesis for
us and will remain a hypothesis for four
or five years until we see whether what
we've done with raspberry pie actually
starts to have an effect on admissions
the hypothesis we had was most of the
people of my age learned to program an
8-bit microwave computers we learnt a
program at the age of nine or the age of
10 or the age of 11 on a machine that we
had in our bedrooms and of my friends at
of my friends at school many many people
not people who eventually went into into
tech careers but just people who went
into all sorts of careers knew at least
how to write that 2 line program 10
print I am the best 20 go to 10 or
something much much filthier than that
and then to go into Dixon's and type
that into every machine in Dixon's here
enter and then run out at the door so
what this meant was a that was
enormously good fun of course but what
it meant was everybody my age who has an
aptitude for computing had a chance to
discover they had an aptitude for
computing or engineering in general and
how does transitive I had a platform
sitting there in their bedroom that they
probably hadn't even bought in order to
learn to program on but they bought to
play games on or they bought to do that
schoolwork that they could they could
use to develop that aptitude and that
was really fantastic starting in I guess
the late 1980s that ecosystem that
wonderful ecosystem and to some extent
quite a peculiarly British ecosystem you
know we seem to have although all
countries had I guess all countries have
the Commodore 64 and most countries had
a national champion computer there BBC
micro equivalent there seem to be just
more of these companies you know the
jupiter's and the the jupiter's and the
tangerines yeah this little little small
speculative computer companies that
maybe never went anywhere in this
country so this ecosystem was largely
destroyed and it was destroyed by two
things it was destroyed from below by
games consoles people who had been
buying spectrums to play computer games
on started to buy Sega's and Nintendo's
to play games on the interesting thing
about those platforms is they're not
just not programmable but they're not
programmable by their very business
model they are designed to not be
programmable they are closed platforms
and they're closed platforms because
they're typically sold at a loss and the
platform holder wishes to recover that
loss through royalties on the software
so they need to control what goes on to
the device and that kind of probably
brings me to thee to the the concern
this concern that we have around
openness is this word open
um I've lived my entire life in an
environment where we have ready access
to powerful open programmable hardware
and because it's been that way all my
life it's very easy for me to imagine
that this is just a fact of nature that
this is just the way the world has to be
so the majority of users of computers
are never going to be computer
programmers the majority of users of
computers are going to be consumers of
computer programs not not producers of
computer programs but because we have
this open hardware we're in an
environment where the producers are in a
sense subsidized by the consumers games
consoles provide a very instructive
image of what the alternative
environment looks like a PlayStation if
I want to write a game for if I want to
write a game for a Windows PC
I'm you're by Windows PC and that
Windows PC cost me the games programmer
the same amount of money that it will
cost the author the the people who buy
my buy my game if I we should write a a
playstation computer game I have to go
and buy a Playstation development kit
now that's problematic for two reasons
one I need to get myself on the list of
people who are allowed to buy a
Playstation development kit so not
everyone is going to be able to do that
secondly while the PlayStation cost
maybe 200 pounds a PlayStation 2 I think
it costs 10 or 20,000 pounds so close
platforms do not have that nice property
that producers can free ride on the back
of on the economies of scale provided by
consumers and they don't have the kind
of the Democratic impact that anyone
with without regard to you know who they
know can start developing content so
open is open is open is extremely
important and open is extremely
important for getting people like
children involved in programming because
children don't have connections if
you're a child and you phone up Sony and
say I wish to write the PlayStation game
I expect that Sony will not respond
positively to that so even if the child
turns up with 20,000 pounds they're
probably not going to be allowed to do
that so open is extremely important
particularly it's open it's extremely
important for all of us in this room
we've all benefited from this but it's
particularly important in education and
it is a
which is under a constant degree of
threat it is particularly at thread
under at the moment as we see an
increasing move towards appliance
computing towards to tablet like
computing towards a world in which you
could imagine that 99% of platforms that
all of the volume will go all of that
consumer volume that pays for fun
programmable hardware will will run off
in the direction of appliance devices
which are purely used to consume so that
was one of the two things and that was
so this is 20 years ago so this is one
of the two things that killed off those
machines the other thing that killed off
those machines was just increasing
sophistication of general-purpose
computers so the PC is an awesomely
programmable piece of hardware it's
probably more programmable in a lot of
ways than the machines that I grew up
with however you have to choose to
program it you can't simply it's not a
machine that you've turn on and it goes
beep and Biggles you into programming
we're a BBC Mike Road the first thing
you have to choose to do with the BBC
micros not to program it you have to
choose to put a cassette in and type
chains you have to choose to do that on
a PC you have to choose to go and get
the tools you have to choose you have to
decide you wish to be a computer
programmer you have to choose to go and
get the tools you have to choose to go
and get the documentation and that
really it's a tiny little barrier
there's a ten-minute barrier yeah maybe
for the first five years maybe in 1990
denies you five before we all had
internet connections it was a little bit
longer than that you actually had to
send off field your program tools but
certainly these days it's a tiny barrier
and you had a vast number of young
people end up stuck up against that
barrier ten-minute barrier it's like
living ten minutes from a fantastic
playground and you never drive there so
our hypothesis our working hypothesis is
that these two effects these two things
together undermined our supply of people
who are interested in and experienced
with computers and prevented an entire
generation now two or three generations
of children who had engineering aptitude
from ever discovering that aptitude
never developing so that's our
hypothesis and a group of us started to
wonder what we could do about it we have
the
idea that maybe there was a niche maybe
Aneesh had been created by the
disappearance of these machines maybe
there was a niche for a machine dip to
find a place in the child's life that
would be interesting to them for some
other reason but which was program which
was programmable which would again start
to beguile people into programming and
we came up with the idea we came up with
the idea that a platform like this would
have to a platform like this would have
to satisfy four requirements first of
all it would have to be interesting we
have to remember as I said people did
not buy their 1980s computers in order
to learn to program on they bought them
to do some other interesting thing and
that was often games and they were just
beguiled into programming so we wanted
something that wasn't just a really bad
bones programming machine in fact early
on we attempted to build machines like
that and what we found was that they
were just not interesting to children so
we decided we needed to have a machine
had a reason we're out of graphics grunt
yeah we settled on games again so we
wanted something what we've ended up
with is a device which is more powerful
it's not a PlayStation 3 on xbox 360
well more powerful than a Nintendo Wii
in terms of its graphics capabilities
complain blu-ray video so we've ended up
with something which has one or two
things that it can do which are not
programming which we think are
interesting to kids of the third one is
surf the web so you know on Facebook the
if you're over 30 so the that was one of
the things another thing we thought was
obviously I had to be programmable and
we wanted a device that had enough
storage that we could bundle every
programming we wanted to eliminate all
these little ten ten-minute steps in
people's lives so we we wanted something
had enough storage that we could bundle
everything from logo and scratch for
your for four to eight year olds to
Python for middle school students to a
secret to a C compiler and a bunch of
standard libraries so we wanted
something that was fun
programmable robust we have this idea
that this is supposed to be a thing that
belongs to the child this is not
supposed to be something that you kit
out that you buy a class set for
necessarily in class and then just have
one class that which is shared around
it's supposed to belong to the child and
so if it's gonna belong to the child the
child is going to do stuff with it at
home and at school
we want it to be able to you know wanna
be able to shove it in your
or any of my shove it in your pocket and
take it out of your pocket a hundred
times there's nothing bad happens to it
and kind of also that kind of implied to
us come small there had to be kind of
portable um and finally it had to be
cheap because we were aware that we were
going to ask people to go and buy this
machine in light of large numbers people
gonna buy this machine often large
numbers and people who don't necessarily
have vast amounts of money we often get
asked actually why the hell are you
building a computer right there are
computers everywhere every household has
a computer it's just simply not true
outside the comfortable middle classes
there are vast numbers of households
which only have appliance computing
devices which have set-top boxes and
mobile phones but which have nothing
that looks like a PC I
I was at a party I was in party last
year and I met this young boy he was
about nine and he was really excited
about computers and he his mother was
there and she was talking about how
excited he was about computers and I
said sure I was cool so what's the
computer he got and she said Oh a
Nintendo Wii you know and there are vast
numbers of households that like this so
we're gonna ask people to go and buy a
general-purpose computing device it had
to be cheap and the the price we settled
on was the price of a textbook so we've
got twenty-five dollars that's the price
of the textbook which is complete
nonsense of course textbooks are much
much more expensive than that I wish we
had known this if we'd known this it
would have made our engineering much
much easier you know we wouldn't have
spent so much so so so long and
optimizing to a cost target but so we
wanted to have this thing which was fun
and programmable and robust and cheap
and we a bunch of us started hacking
away at machines so there's a bunch of
us in Cambridge and a chap called Pete
Lomas who's up in Warrington and who is
I think in the Manchester audience so
you so people in Manchester can bother
him afterwards and asked him to stand up
on identify himself at the end of the
talk the so anyway this group of us
started wondering about what we could
build I went to work for whom do
Broadcom I didn't stick at the
University so I went to work for a
company called Broadcom and the lovely
thing about Broadcom for whom I still
work is that we make these mobile phone
ships that have enormously powerful
graphics processors in and so by about
2009
we'd actually managed to throw together
a prototype machine based around a
broken graphics processor which met all
of our requirements what we thought
would be to all of our crimes obviously
cost is
was extremely hard to hit until you're
really building him significant volume
so we thought we were doing pretty well
and we were trying to solve still try to
solve a very little problem yeah we were
trust all the problem for Cambridge we
really promote we really parochial
people we thought you know we just get
another hundred kids or we can just get
the kids who are coming in and get make
sure that they know a little bit more
when they come in the door that'll solve
our problem so we were really thinking
in terms of a thousand raspberry pies we
thought I'd be a lot of raspberry PI's
ten thousand raspberry pies over the
lifetime of the project and we were we
were kind of pottering along at our own
rate and then and because a number of
the people who are on the board of
trustees of the foundation that we
incorporated to try and pursue this have
a connection with the BBC micro most
notably as a chap called David Braben
anyone played elite there we go
so the chapel David Draven is one of our
trustees in leech was probably the best
game for the BBC micro I got my start on
the BBC micros and we've really wanted
to put a BBC brand of this we wanted to
put a BBC bramble this on this product
so badly and we kept having these
meetings we have meetings up with BBC
R&D in Manchester and meetings down in
London and we really wanted to put a BBC
brand on this and what we discovered of
course is that the BBC is no longer able
today the BBC could not do the BBC micro
project the BBC is a state-funded entity
it cannot just go and muscle in on the
world of making computers anymore it
would just work and our very last
attempt to do this was in May of last
year we went to see a guy called Rory
Katherine Jones who also told us no but
what he did say was could I take a video
if your of this thing and and put it
I'll put it on my blog yeah I think it's
an interesting idea what you're trying
to do I because he can't support it
formally but I like it so because we're
idiots we said yes and so that one
Rory filmed a video of David holding up
a very early prototype of this board and
put it on his blog and we got 600,000
YouTube views in two days which was
really fantastic because I was sitting
there pressing f5 and my and how popular
are you but number was going up I don't
know yeah it didn't do any work at broke
on let's do this and the
and on that and I felt really fantastic
and all of us at the foundation fact
that felt fantastic and on the the
second day I sat down for dinner with my
wife Liz and across the dinner table and
we suddenly realized that we promised
six hundred several fan base with no
money and we promised six hundred
thousand people that we build him a $25
computer and that was a really awful
experience and so to some extent for all
of us in the foundation the last year
has been a story the last now year and a
half has been a story about us trying to
make good on that promise that we ended
up accidentally making to a much larger
constituency than the one that we
originally had in mind for us we buy so
how did it go we said it'd be great to
get this out by the end of the year we
said let's try to get out in q4 we made
a public statement we wore the press
were getting in touch with us in the
aftermath of this thing with Rory and we
said yeah we got to try get this thank
you for we learnt it we learnt a real
lesson there if you say Q for people
average it's an averaging tendency of q4
means the 15th of November on the 16th
of November last year I stole my first
story in the press Roz be pious late we
so so there was there was a lot of a lot
of frantic engineering we had an
enormous amount although this has never
been a Broadcom project there's always
been a there's always been kind of a
theory out in the wild but this is a
sneaky Broadcom strategic marketing
project to get this chip into all of
your hands
it really isn't but we have had a lot of
soft support from broker
one thing the Broadcom did for us was
that they manufactured for us our first
50 what we called alpha boards which is
like a Raspberry Pi but bigger or much
more expensive they cost a hundred and
seventy seven dollars to make they're
never going to be the real deal but they
are electrically they make a great
software development platform and they
allowed us to prove out the design of
the schematic level then between and
those came back in August and people
were really quite impressed with some of
the software we were able to run on them
and then really between August and
December was a big effort to cost reduce
this device an effort largely run by run
by Pete to to cost reduce this device
and I we got our what we called beatab
which was supposedly manufacturing
candidates I got a phone call from Pete
when I was somewhere else on Dartmoor on
the 22nd of December to say they've come
back and they don't boot unfortunately
there was one thing wrong with the board
so the next day I got a phone call from
someone at the office in Broadcom TV
turd FedEx the board saying hey boat so
we have some working devices we have
these working be towards we have 25
Peter boards they mostly worked and so
we were able to do in a paper launch we
were able to do an in video style paper
launch on the 31st of December we sold
10 raspberry pies on eBay and we sold
them for $1,000 each at auction and that
was really and that was fantastic
because you know we have always you know
one of the things that Rose replies all
the struggle for is all the struggle for
money because we're a charitable
foundation we can't go we have a device
which is profitable to manufacture and
we've never been able to go and raise
any risk capital and while so it was
great we've got $10,000 but it was
actually very worrying when we thought
about it because when we thought about
it what this meant was there was so much
interest in the pie that people would
bid $1,000 for a beta board and we had
one other indication that things might
be going wrong and that was that to keep
people's interests up wallet while we
waited to provide them with pies we put
an operating system boots 'men SD card
and we put an operating system image up
on the up on the up on the Internet and
for people to play with and we got just
in fact really to come in loves it and
have a look at we've got 50,000
downloads and that was really worrying
because in our minds we'd be thinking
600,000 people they're probably all
rubberneckers right there's probably
actually really is only a thousand
people and so we've capitalized up we
did all of our trustees we've all put
money in the put money in the pot and we
managed to capitalize up so we could
make 10,000 Osby pies and then we found
out that there were 50,000 people so
hardcore in their interest in raspberry
pie they were prepared to download a 2
gigabyte image for a machine didn't
exist yet and that they have no idea
when they were going to get and it was
an alpha quality and that was the point
where we realized that really was that
we were going to have a surprise in the
way of in the way we thought we'll make
10,000 we'll wait until they sell out
and then we'll have got our money back
and we'll make another 10,000 and we
started thinking oh we might
actually sell 10,000
it's in the first few weeks and then
that's going to cause a reportable MBA
they'll be there be a shortage while we
make another 10,000 at this point we
were very lucky to to bump into two
companies I called electric components
and premiere Fornell and the lovely
thing is these are companies who share
our concern they share our concern about
the supply of Engineers because
engineers are their lifeblood and so
concerned were they and so you know
interested in raspberry-pi were they
that they agreed to manufacture them for
us and this was really this has really
been the the engine that's enabled us to
do interesting stuff with raspberry pie
this year a volume is that these
companies do not simply buy raspberry
pies from us and distribute them but
they license the design for raspberry
pie and the trademark trama and they
commissioned the build of raspberry pie
and they also provide all the
distribution in customer service of what
this has meant so we in the last two
months before launch between those 10
units and launch day we completely
changed what it is that we do we were
going to be a very capital constrained
regular manufacturing company and we
turned ourselves into an IP licensing
company that's really been our salvation
I think this year we launched on the
29th of every which was really stupid
because it denies us the opportunity for
a first anniversary party we're we're
going to have a really great 4th
anniversary party we now save up all of
that money invest it somewhere um so so
we so we lost on 29th of every we saw
100,000 rose rose on the first day so
the that was the right definite the
right thing to do to do the licensing
thing obviously you know this year
there's been a lot of struggles to get
the thing out the door and we have to
date shipped four hundred thousand four
hundred thousand dollars buys and we
think we're on track
thank you um we're on track we think to
do a million units by our first
anniversary we won't quite get to a
million units this calendar year but we
think we can probably have two million
years behind it by the end of February
um I was looking at the foundations so
we're in into place but I was looking at
the foundations founding documents the
other day as you do and it's a laugh a
minute my house and the we look and
nowhere in those family documents does
it say we are going to build a lots of
little computers for everyone what it
actually says is we're going to get kids
programming again and so really for us
we're now at this point where we've
we've accomplished it up this what I
think is always a wonderful thing and
that's really exciting but it wasn't the
thing we were intending to accomplish in
there for very much for us as a
foundation the next year has got to be
about kind of starting a pivot round and
turn back towards actually accomplishing
the things that we want to accomplish
and that means several things
it means software but most importantly
it means teaching materials it means
the things that you need in order for
we're starting to see this academic year
raspberry-pi being used in some schools
by some teachers who typically they're
the two things that I love that I've
already seen the pipe we're seeing some
teachers not necessarily I see some ICT
teachers but some physics teachers
teachers and all sorts of subjects who
happen to have a personal passion for
computing using this as a way to inspire
kids around them and that's amazing the
other really lovely thing we're seeing
is we're seeing parents using these as a
way to talk to their kids engineer
parents who are engineers using these
devices as a way to talk to their
children about what it is that they do
in their jobs and we have we just get
wonderful emails really heartwarming
emails that keep us going but from
people who say you know my kid was never
interested in programming a PC you only
want to do on PC was go and you know go
on Facebook
I'll show them arrives to be PI and
actually something about the fact that
it's really bare-bones and approachable
made him think oh I'm going to try doing
this and before you know it he's making
a little cat run across the screen and
e-cell I made a cat run across the
screen so that's and that's extremely
nice so we are starting to see some use
of Raspberry Pi in this borrowing kids
to really accomplish our mission though
we need to make this something that can
be deal
everywhere and we need this to be
something that can be delivered because
of the we have a skill shortage not just
in ICT engineering subjects but we have
a skill shortage in the teaching of
engineering subjects this needs we need
to turn this into something which can be
delivered into a what we sometimes call
a tech phobic environment I'm not sure
that's probably the right word but
certainly an environment where we cannot
rely on a high level of intrinsic
technical understanding in the people
delivering the course and that's really
what we're going to spend the next year
doing this is a wonderful time to be
doing raspberry pie we are enormous ly
lucky that there is a realization there
is a broad realization that we are
really in trouble as a country from the
point of view of STEM skills obviously
it helped to have Eric Schmidt to turn
up last summer and tell the government
that they were out of their minds to be
throwing away Britain's heritage the
various in various innovations that have
come out at various reports that have
come out of places particular all
society the the Livingstone hope report
has been enormously influential the
games industry seems to have really the
games and visual effects industry really
appear to have taken the lead in trying
to bang the drum about how there's a
problem so we're in a position where we
think we can we think we have we think
we have a product that can be used to
solve this this problem we have made a
lot of noise and really we have this
two-year period now while the government
revises the curriculum while we
currently there is an ICT curriculum but
they there's a thing called dis
application that's happened so although
there is an ICT curriculum here as the
school are free to ignore what it says
and go and do whatever you want with the
time and money we have a two-year period
of opportunity to decide what we want to
do and raspberry pie is enjoying being
that as a foundation is enjoying being
part of that discussion so just to prove
that people I know many of you have
raspberry pies just to prove that people
do fun stuff with raspberry pies I have
the shortest of slide shows of things
that I've seen over the last six months
I've enjoyed first a few projects people
have done with this we didn't see this
one coming at all
this is music synthesis people have
using raspberry pies as this is a four
note polyphony digital analogue synth
on the pie and it's called piano and I
think that's actually going to be a
commercial product we're seeing a lot of
this we're seeing people use Raspberry
Pi in commercial products and I think
we're extremely relaxed about this
people do sometimes ask us whether we
mind other people make or because we
don't make money out of raspberry pies
individuals people sometimes ask us
whether we mind other people making
money of course we do hate those people
so anyway so this is so this I believe
there's going to be a commercial product
and it's going to be commercial product
real soon
who doesn't like there it's amazing how
many people's first reaction to a
raspberry pies I can use this to brew
beer I'm not just homebrew you know I
would have for you in a home grid but
there's a thing called brew pie now
which is an open source brewery
controller that you can use to control
up to medium scale craft microbrew
breweries and it presents a beautiful
web interface that you can use to tweak
up your prezi hopefully with plenty of
security you can used to tweak up the
temperature of your mash yet we said we
wanted to make the pie interesting to
children in ways which are not about
programming we don't want around
programming down their throats we just
want to kind of leave programming next
to them and see if they pick it up I'm a
big part of this for us is about games
we're very hopeful that there will be a
commercial games ecosystem around
raspberry pie this is not a commercial
quality game although that water effect
is enormous the expensive to render but
this is penguins puzzle which was
written by a good friend of mine in
Cambridge and which now ships with the
pie you know just trying to kind of make
this an interesting and attractive thing
for games light yeah lots of people
doing Hardware interfacing projects to
the pile
I have to confess that I'm a software
engineer I I would not you know I'm not
an electrical engineer and so my
imagining about what cool things people
would do with a PI were all software
imaginings even as recently as last year
I thought everyone I thought we've got a
fantastically powerful GPU on the device
and I thought man people get any great
graphics demos because that's why I used
to do as a kid and that's the thing I
care about almost everything that has
been done with the Raspberry Pi that has
been exciting to date has been in one
way or another
project and this is a we've been very
lucky there's an organization called
Adafruit based in the US who have taken
the pint of really pushing it into the
US market this is a nice little
persistence of vision light warm fish
fish pie I've got another one on the
next slide I really hated the name when
we first came up with it III was i
raspberry pie raspberry and fruit named
computer companies and pi is the fact we
originally intending one of the doomed
projects that was only a programming
device only ramp I think it surprised
the pine Python misspelled but the dusky
I hated it for the first year I thought
that was a great idea shame we gave her
the crap name and but it does keep
living it does keep giving us wonderful
puns this is supposed to be a remotely
of an autonomous boat that is going to
pot around the North Atlantic it's a
Kickstarter project so if you want to if
you believe if this picture makes you
believe then you can you can contribute
to meet success this is the one I love
this one is called pie in the sky this
is a gentleman called Dave Ackerman he's
based in the South of England and he for
a long time has been putting digital
still cameras and video cameras under
Helium weather balloons and sending them
up and taking pictures and then
recovering the pictures when the when
the device comes back down this was his
first attempt to use a Raspberry Pi to
do that and the last thing was using a
Raspberry Pi he was able to send the
pictures down live so Raspberry Pi from
the heartbreaking thirty nine thousand
nine hundred and ninety-two meters so
this is little qvg a picture of the
Earth from space and it holds the record
to the highest altitude pictures ever
sent down from an amateur click there we
are I'm a Don boards this big ecosystem
appears to be appearing around around
the PI this one's a thing called dirt
board
it's a IO expansion buffering board for
the device gives you ability to do
things like drive motors the foundation
isn't really one of the interesting
things about the foundation is that
we've got these very modest goals really
all we want to do is really want to make
this thing and then we want to do the
education stuff we don't necessarily
want you see it doesn't come in a box
and we're going on
in the moment this is left by accident
and an enormous amount of space normos
Metamarkets space around the pie an
awesome amount of space that people can
use to go and make money and this is
this is a good example of that in fact /
we're going to have this as a friend of
mine Arduino Arduino this physical
computing thing is really interesting
because I think I'm the product of my
time and I think the software is
interesting actually if you look at what
kids find interesting today making a
little dot move around on the screen is
remarkably nowhere near as cool as it
used to be what kids find interesting is
making a little thing move around on the
floor and if you go and look at you to
the extent that there are bright spots
in the in the extent of which kids are
engaging with with electronics and
engineering the Arduino has had an
enormous impact if you go to a Maker
Faire when these Maker Faire events you
see vast numbers of eight-year-old kids
with you know like a little doll's house
that's got lights that turn on off when
you flick switches and almost all of
this is done with Arduino and there's
been a real attempt I think because we
kind of look a bit similar and we kind
of a similar price has been a real
attempt to set us up for some sort of
like competitor for Arduino but actually
we fit incredibly well together see a
vast number of people now using Arduino
and pie hill what's good about Arduino
very low power very low cost what's bad
about Arduino you need to have a host PC
to run it from what does raspberry pi
give you it's a very very very cheap
host PC so we're seeing an enormous
amount of this sort of thing people
connecting raspberry PI's on arduino
together kind of hoping our distributors
will start off with bundles at some
point camera i said we weren't going
into the adam ward business we are
getting into the add on board business
as a to add or boards we're going to
make one of them is is a camera board
one of them is a display board the
camera board of which this is a very
early demo it's going to be really
really useful because another thing we
see a lot of enthusiasm for my own kids
is not just making robots to move around
but robots to move around and can
interact with their environment and this
is going to be very useful on this we
can do very cheaply in a very high pod I
wrote a book I feel like such a whore
putting now on my slide deck sorry there
is really one of the nice things is yes
okay I wrote a book and you have to pay
money for the book there one of the
lovely things is another ecosystem thing
that is happening is there's a vast
amount of free tutorial material around
this device we've been very focused on
the idea that there's not much point in
building a $35 computer if you have to
go and buy a hundred dollars of stuff in
order to get any value out of it
so some extent that's shown up in our
use of televisions as displays and
mobile phone power adapters as power
supplies but it's also shown up in our
encouragement and you know the extent to
which we've promoted free tutorial
material online really lovely free thing
that's happened is this simple grasp but
anyone been to a raspberry jam okay
raspberry jams are great they are
somewhere in the space between
conferences and computer clubs and user
groups and support clinics they they're
a venue that people can use who've been
doing stuff with raspberry PI's to share
the interesting stuff they've been doing
with Raspberry Pi and critically from
the education point of view they're a
place that teachers who are interested
in the Raspberry Pi but do not feel they
have the confidence to deliver teaching
material around the Raspberry Pi can go
in order to find out more about the
Raspberry Pi and to meet teachers who
have successfully delivered
Osby PI based stuff in the classroom and
these things the for the Foundation's
point of view the great things about the
great thing about raspberry jams we have
nothing to do with them they don't
consume any of our time or energy
there's an enormous enthusiastic
gentleman called Aldo Donahue who
organizes and runs these things around
the country pretty much off his own bat
just fantastic and these have happened
as far afield now as Australia and the
west coast of the US another wonderful
thing we have a magazine with type-in
listings I mean I spend a lot of my time
as a child typing in listings and there
seems to be something wonderful about
when you type in when if you type
something in as opposed to downloading
it from the internet there's something
wonderful when you type it in it goes
through your eyes through your brain out
of your fingers and at that point you're
and you probably make a mistake and from
your mistake you learn something
interesting and from it having gone
through your brain you get a little bit
of ownership and understanding of what
it does so we have a magazine again this
is nothing to do with us this is just in
very enthusiastic people it's now an
issue six the first five issues through
five first five issues or electronic
magazines the six this year was is being
printed so it's actually a print
magazine it's a print magazine
specifically because teachers were
getting asked by their kids whether
there was anything that they could leave
around that they could use to learn
about the Raspberry Pi so this has been
printed in order to provide collateral
to leave running classrooms I got back
from the US last week and I found a big
pile of them on my doorstep and I should
have brought them with me today um I
said we didn't make you big ecosystem
around the pie
we didn't case it we didn't case it
because we thought we're only gonna make
a thousand of them an injection molds
cost 10,000 pounds it didn't seem like a
good spender the money at the time I'd
love to claim we didn't case it because
we were going to create a fantastic
casing ecosystem but in practice it was
it was an accident well we created a
fantastic casing ecosystem this and make
that all the niches are filled this is a
very cheap case this is a PDF that you
can download and print onto the thickest
card you can get through your printer
it's an insight living in citement to
printer jams and it's called the Punnett
and you fold up and it makes really good
rasp my case um Legos ah yeah so I now I
knew I should have edited this since I
came back from the US yeah Legos this
case was the the size of the board we
sort of wanted it to be credit card size
and it is so near to being credit card
sized it's about a mil away in each
direction from being a credit card we
didn't realize that the slides we have
picked is an incredibly close multiple
off the Lego basis unit size and this
means that case is made out of Lego fit
really really well this case this case
was designed by a girl lovely old Girl
Scout called biz and you can now buy it
online you can buy a kit to make this
online and biscuits royalties and
because she's an 11 year old she takes
her royalties in Lego so she now
she now has more she now what they go
through anybody on earth Legoland funner
off loans anyway so so but this is
interesting and this this some of this
stuff is this this kind of peripheral
stuff it shows I guess for how limited
my imagining of what sort of creativity
people would get up to if we gave them
raspberry PI's Basel I was really
thinking about graphics demos I was not
thinking about robots and I wasn't
thinking about that this is PI Bo have
any of you got a PI Bo hey there we go
okay
hi Bo's about ten weeks old eyelid
twelve years old maybe now I saw a
prototype this is a this is a case this
is the deluxe this is the rolls-royce of
Raspberry Pi cases it's made out of
stacked laser-cut acrylic it's one of
the most incredible I don't have one
with me annoyingly it's one of the most
incredibly beautiful things I've ever
seen
I saw this at the start of July for the
first time a prototype at a conference
in Sheffield and there was a
seven-year-old girl walking past and
Paul beech who who designed this and
actually designed our logo for us as
well I took this out of his bag to show
me and this little girl's walking past
my head kind of snapped around like that
and she was like oh there it is oh it's
so pretty can I can I come and get it
and hold it out because it's just such a
pretty thing I want to touch it
I will give it back don't worry I do
have some Oh awesome oh that's still
weird
so yeah that's the PI bow when it's
assembled I mean it's probably a small
dot for most of you this is this is
fantastic
and Paul beech has sold 12 thousand of
these in 10 is gone from nothing from
having one prototype to selling 12,000
of these and having a factory in
Sheffield that makes them in 10 or 12
weeks and this has been just this is the
another really nice thing not speaker
system around it and lots of people
doing really fun stuff we said we're
honest bye kids this is Mikey Mikey is
off-screen there well he's got Lego
cakes and Mikey is off-screen learning
to use mit scratch enormously popular
for teaching kids
I think Mikey's dad as an engineer so I
think he's amazing member of that a
group of people who are being shown how
the program wise by their by their
parents I said we had a very parochial
focus as raspberry-pi interested in
solving a little problem in the UK turns
out everyone wants to program these kids
are in utter Pradesh in in India and you
can actually see on screen here we have
MIT scratch down there so one of the
really interesting things for us is that
although we were very focused on the UK
oh come on
Oh spoil my for my surprise there we are
although we were very focused on the UK
they've ended up everywhere this is
really something that we have our
partners to thank for our largest market
is now North America a largest per
capita market which I find really
encouraging is actually still the UK by
a long way so North America is slightly
bigger than the UK we're selling about
the third shipping between one and two
hundred thousand units a month for the
moment about a third of those into the
UK further those into North America
third into the rest of the world and the
rest of the world mostly means what
makes Europe at the moment but we are
starting to see signs of life in South
America starting to see signs of life in
India not much for the way of signs of
life in China at the moment and that's
really something I work on over the next
it's just really encouraging it everyone
program right um when we decided to
manufacture this we did the same thing
with everyone and so I gave you my thing
that I'm concerned about which is this
openness issue and the closure of
platforms give me the thing I'm
optimistic about when we decided to when
we started to manufacture this thing we
did what everyone did which is to say
well everything's made in China right
and so all of these this pie was made in
China this was made by our contract
manufacturing Shenzhen and about a month
after launch we heard from a contract
manufacturer in Wales as of about six
weeks ago probably a majority of
raspberry pies I actually built in
Bridgend this lady's called Jane she's
one of 30 people who manufactures
raspberry pies in Wales it turns out
it's as cheap to manufacture in Wales as
there is in the Far East and that was an
enormous surprise to me I think that
it's that the harbinger of a trend that
we're going to see a lot of I think it's
important now whenever I get a chance to
stand up in front of people I bang the
drum that there's a crossover happened
right wages in China going in one
direction currencies going in one
direction shipping costs are going one
direction on I think we have already
crossed over to the extent that a well
organized professional UK manufacturing
operation can build very low cost
electronics like this more cheaply than
you can build them in China with effort
I mean took six months of effort from
the foundation from our partners and
from Sony our contract manufacturer to
make this happen
but it's just really really encouraging
and it's great and going there and then
we're also peopIe shooting off blinder
than you kind of worry about two and a
half thousand a day so that was fun
anyway that's all of my slides um
slide share a few things we um thank you
very much for listening I guess so I
just asked for questions
what are you okay okay thank you
