so so yeah so I'm here to talk about this

this is a Raspberry a Pi does anyone in the audience have a Raspberry
Pi?

awesome 
 
I'm still in I'm still kind of in this in this place where, this time
a year ago I had a spreadsheet on my computer that told me where every
Pi in the world was so it's of it's just it's great you know of very
many of you here I don't know so that's really encouraging
 
the Raspberry Pi for those those you who haven't seen raspberry PI's I
have two ... Are there any personal injury lawyers in the room okay in
that case (one  RPi in the box out into the audience)

these do need these do need to come back because they are the door
prizes but I'll ...that over there cool (throws a second box into
audience)
 
Feel free to unbox it and take a take a look at it so you have some
idea what we're talking about
 
I guess today I thought my talk 
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 thought we could solve it with something like this.
 
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
and maybe some risks that some of us
in the foundation have.

there were concerns that we have about the risk of an increasing level
of closure
 
the hardware that we're that we're accustomed to use, to give you a
little bit of the the of Raspberry Pi how we got from thinking there
was a problem and now quite a long time ago ...  I've been giving
variants on this for so long that in all of my slides I say it's been
a six-year journey it's really
getting on towards the point where 
been a seven-year journey

so I'll share a little bit about some of the things that have happened
at about where we
got to now and then I was 
going to -- 
I don't really have any slides --
talk that

I was going to conclude with a few pictures that I think we've been in
the wild for or seven months now some pictures which I which I think
some of the uses that people been putting PI to so as James ..  pi 

PI
for me is something that
out of the end of my time as a PhD
at the University of Cambridge I 
 
I came up to I came over to Cambridge in 1996 as an and at that point
we had a very healthy typical Cambridge ratio -- yeah we had a six to
1 application application ratio so we and we were blessed not just
with candidates but with high quality candidates so of people we let
in the door -- and a lot of the people we rejected -- we could rely on
all of those people you know having been programming maybe even as
much as a decade of programming computers

I myself came in the door with a couple of a couple of kinds of
assembly language programming and that was a pretty typical
set and in fact the problem that 
faculty had at that point was 
not so 
teaching not so much kind of 
people up to speed as 
these people who came in the 
that we didn't know everything

now we had a thing called we had thing called functional programming
we would subject our first years to could you know hit so these in
accomplished young people come in the door we'd hit them the head with
standard ml for eight and then when they would come up the floor at
the end of that we could start to build them up and of
 
being able to have such a fast pace
is enormously important set in the 
system because we have over a 
course only 60 weeks of contact 
to turn somebody from the six (form)
into somebody who can start a PhD 
 
 
being able to make a really fast was extremely useful and to some
the department have got very fat 
& happy on this stream of this stream
very talented people. 

now by the time I was finishing my PhD 2005 and I took a job as a
director of studies. now people have been through
Cambridge system the world will know 
job of the director of studies 
is to direct
how the undergraduate  
is organized.  undergraduate teaching.

also to organize the supply of the new applicants to go out to schools
and evangelize the subject it is you're in, and then to interview
people who come in the door in December and try and decide who to to
take on

um and it was kind of a bit disappointing because what I saw over
those ten years between arriving as an undergraduate and starting to
interview new students was the number of people to read computer
science at Cambridge had high gone from maybe 500 applicants for about
90 places to to maybe 250 or so
 
still it that's still you know a good a good cover ratio but it's not
like what we were used to

but alarming for us the average skill of the people coming in the door
had changed from a of assembly language and graphics to maybe having
done some HTML a little bit of web programming if were lucky now
there's nothing wrong that and these are still extremely bright
people; we're still able to fill fill our lecture halls with 80 or 90
bright young people but the problem is that we had to spend a lot of
time our first year bringing people up to level of skill that we'd
previously able to assume.  

and this was
extremely worrying for the 
anything that's worrying in 
way for a university is probably 
to be worrying for industry 
thereafter you know if people if 
if people stopped coming into into 
in severe number in your X 
your X plus 3 or X plus 4
to stop turning up at in industry 
 
 
I've ended up in industry I have this it's just subtly to look around
at the number people in their late 20s and their and then the number
of people in early 20s

increasingly for us I (after coming to work for Broadcom ) ... for us
hiring means poaching away mid 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 worried about this a group of in the
Cambridge the Cambridge were worried about this and we to wonder A why
this had happened us and B whether there was anything could do to try
and fix the problem the hypothesis we came up with and us it really
still is a hypothesis is still a working hypothesis for and will
remain a hypothesis for four five years until we see whether what
we've done with raspberry pie actually is goin to have an effect on
admissions
 
The hypothesis we had was most of the 
of my age learned to program an 
Acer micros computers we learnt a 
at the age of nine or the 
age of or the age of 11 on a 
machine that we 
 
in our bedrooms and of my 
school many many 
people -- 
 people who eventually went into into 
careers but just people who went 
all sorts of careers knew at least
to write that 2 line program 

10 I am the best 
20 go to 10

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

thank you
