Despite all the excitement and expectation encompassing the RaspberryPi, the most remarkable thing about this low-power credit card-sized computer is its price tag: little more than £20 for a fully functional system capable of, among many things, 1080p video playback and hardware-accelerated graphics. The British-designed Pi …

      Head over to the RPi forums, it's discussed there... I'm sure we'll see emulators running very soon after they're made available - which is great, but it's not really the point.

      More than capable

      The r-pi will be more than capable of emulating lots of classic systems... just gotta port em.

      probably expect a lot of arduino projects to get ported...

      be intresting to see a reprap powered by one of those, almost a perfect educational device then

      Now just have to convince the misses that i really need annother board, to got with my arduino's and netduino's ;-)

        RISC OS

        Elite already runs natively under RISC OS on the ARM so once the RISC OS port is complete, that solves that problem. :)

        I'd stick with an Arduino... least to my knowledge, the GPIOs aren't buffered on the RasPi, and there's no analog I/O.

        And, if you blow up an I/O on the RasPi (which, my understanding is that's easier), you've gotta replace the whole board. Do it on an Arduino, and you need to replace a $4 chip.

        But, a RasPi would be a good supplement to an Arduino for additional processing power...

          You can get - for a bit more than this - a Arduino shield and largely code-compatible ARM Maple already. If you don't want shield and software compatible, there are tiny ARM-powered boards with loadsa-IO ports exposed. If you want Arduino plus 400x300 VGA, there's the lovely Gameduino.

          The Raspberry is optimised for getting stuff on a screen vs hardware IO for the Arduino/Maple.

      Well if they get RISCOS running on this thing then YES. It'll run Elite and even better... it'll run D.Braben's other scifi game that amazing Zarch (of which a demo was supplied with every Archimedes under the name 'Lander'.) Zarch is better knonw on non-RIISCOS platforms as 'Virus'.

      A beautifull game with a 3D vector-drawn isometric landscape. One of those unique games that unfortunatly never achieved the some success as Elite.

      In fact I wonder why none of these old scool games never get ported to cell-phones. I mean even the ZX Spectrum had unique games (Marsport, Dun Darach, Tir Na Nog comes to mind) or the C64 (Head over heels, Zaxon) These could easily be ported to todays cellphones without (ab)using too much performance. But to stay in the RISCOS world. I'd love to see a proper port of StarFighter 3000 or even StuntRacer2000. They where both totally addictive (as well as Zarch by the way).

      Perhaps Mr. Braben could supply 'Zarch/Virus' free with every machine sold (as an incentive to potential customers). IMHO I think Zarch is the more appealing game instead of Elite.

    Darn. Only one Ethernet Port.

    If it had two, it would make a brilliant router. Finally a replacement for a second-hand WRT54G!

      Re : Darn. Only one Ethernet Port.

      "If it had two, it would make a brilliant router."

      Ethernet over USB maybe ? I'm sure the online discussions and fora will have much advice and thoughts on the matter.

      Rather looking forward to their release I must say.

    2. Nigel 11

      USB Ethernet?

      Assuming the USB is USB2 (someone confirm, please) then you could plug in a USB Ethernet adapter for the second port. Of course that does add £15 - £25.

      It's also a shame that there are few USB ports. Keyboard, mouse, disk and memory stick or DVD drive, I'd have liked 4. One could plug in a USB(2?) hub, but that's ugly compared to integrating the hub chip and , say, 4 connectors. How much would that cost - less, surely, than the £5 you can buy such a hub for. I'm sure it wouldn't complicate the board, just (maybe) make it a little larger.

      Even so, if I can buy one as shown for under £30, I probably will. If it winds up at £100, I probably won't. I'll probably hack it into / onto a monitor, tapping the monitor's PSU which can almost certainly supply an extra watt.

      1. No, I will not fix your computer

        Re: USB Ethernet?

        The whole point of the board is to get the price down, even saving 25p is worth it - read the article! adding another USB or Ethernet is the *wrong* idea, after all, what would be next on the list USB3? surround sound? PIO disk interface? firewire? thunderbolt? nope, I'm sure that even one Ethernet was carefully considered,

        1. bhtooefr

          And that ethernet interface is an optional extra (along with 128 MiB of the RAM).

      2. Nigel 11

        I did get it ...

        I understood the point about getting the cost down. In my dreams it would have boasted SATA but I fuly understand why it doesn't. I'm not an electronics engineer so I may be complertely wrong about the following, but I'll fill in my thought process.

        A USB hub chip is obviously a stand-alone chip plus support components connected to a computer system by four wires. Usually it's packaged in a little bit of plastic and the four wires are the PC-to-hub USB A-B cable. Therefore I would have thought it possible to design this system's circuit board so it can be populated either with a single USB connector, or with a USB hub chip and a quad USB connector. If I'm right the extra cost of the cheaper version would be the price of the extra PCB area needed for the (missing) quad connector abd USB hub chip. It's bad idea if (a) I'm wrong and it's not possible, or (b) if the extra cost of a small bit of unpopulated PCB on the cheaper version is enough to put off a significant percentage of customers. I doubt the latter.

        Anyone with more detailed knowledge of board design or economics care to make a well-informed comment?

        1. James Hughes 1

          There are two chips on the Model B board - the SoC and a LAN chip. The LAN chip is multi purpose and takes the SoC single USB and converts it to ethernet, and also provides a two port hub.

          This is a pretty cheap option - higher hub count and the required connectors increases the board price quite surprisingly - you need the bigger 4 port USB socket, the hub chip, and the board space on which to mount them - space is money. All together they put the price up by over 10%.

      3. Mad Hacker


        This is a bare board with exposed electronics components and adding a USB hub is "ugly"? I have a regular computer that encloses all the electronics and two additional 7 ports hubs on my desk behind my keyboard. Pretty standard to need a USB hub or two on any computer these days.

        On the other hand I have a Dell keyboard that provides a USB port for the mouse so if you only needed a keyboard and mouse and had a keyboard that provided a USB connection, then you wouldn't need a hub at all.

        1. Nigel 11

          Ever heard of a box?

          I did visit the RasberryPi web-site. A box to put it in is planned, though it won't be available on day one. Then it'll be a neat little (tiny) box with a USB hub dangling from it. Ugly.

          I'll also be paying more for the hub separately than it would cost integrated into the Pi. But that's all argued over above. If the added cost of unpopulated PC board real-estate really is enough to deter sales of the cheaper one-USB version, then ugly it'll have to be. (It's not much real-estate. USB hub chips are tiny and since the single/quad USB socket is either/or, they'd share most of the PCB location). Anyway - since it's less than the cost of a couple of pints, the money (unlike the aesthetics) isn't an issue for me.

            A box?! Buy a tin of Altoids mints. Line it with something non-conductive, and you have a very strong case for your little computer. Hell, mount it upside-down with a thermal pad from the CPU to the tin, and you could use the tin itself as a heatsink. Might be good for getting a couple hundred more MHz out of the processor.

            This is on my wishlist.

    4. The Indomitable Gall

      Hopefully some good will come of this.

      In the early days of USB it was claimed that USB didn't need to be daisychainable because it's so cheap that every peripheral would include a hub. But that never happened, did it.

      In my opinion, the correct place for a USB hub is in the keyboard, which can then become that holiest of holy grails: the universal docking station.

      Unfortunately, that was what should have happened years ago. It's unlikely to happen under USB 3 as who in their right mind is going to make a USB3 keyboard?

      But still, we should have been at the stage by now where the majority of keyboards had a pass-through port for a mouse, and hopefully devices like this will finally start the creep towards that....

      In other words - simple but fun.

      I'm quite looking foreword to the RaspberryPi kit, as it seems like a good dev platform, plus it's basic specs blow the BasicStamp and Arduino (and their clones) out of the water. Plus the price is right - unlike chip mfgs dev kits that cost as much as a cheap laptop in some cases.

          Using APIs has its benefits...

          "I really hope Raspberry Pi is open and we can all get down to the metal on it but if Broadcom is involved, somehow I doubt it will be."

          If you look at open-source hardware projects, they usually sink because the specced components aren't available any more, but the Raspberry PI is as damn near generic as you can get. Ethernet controllers and USB controllers are pretty generic. ARM may be a propietary design, but it's licensable and so heavily commoditised. This means that they should be able to revise the hardware as the market changes and use components from other suppliers without invalidating the existing codebase and forking the system (and userbase).

          The only truly closed component is the GPU. There really is no such thing as a generic GPU on the market, and GPU technology is changing rapidly. Mandating Open GL makes any GPU generic, and this means that they can change the GPU later when the current model is discontinued or they can negotiate a better price with another supplier.

          On the other hand, if the GPU's native APIs were available, you can be damned sure that developers would use them, and software would become irrevocably tied to the current version of the hardware, which would destroy the long-term potential of the project.

          @ @Cowturd

          Yeah but if a lowly Nokia N8/C7 with it's measly 680MHz ARM11 can record and play 720p then who are we to complain about not having enough oomph?

          It's clearly a matter of optimising the OS. RISCOS on an 8MHz ARM2 equipped Archimedes A440 ran circles around my Atari PC4 (80286 16MHz) at that time (one o/t reasons I ditched my PC and Amiga with its 68030 to get an A5000). And later (early 90's) my ARM3 equipped 25MHz A5000 was a lot faster than the usualy PC clone 80386SX/DX. Things didn't change much untill the Pentium 2. Then with the arrival of dedicated graphics-accellerators and the much higher clockspeeds PC's began to overtake the Acorn machines in performance.

          The Achilles heel of the Acorn systems was their abysmal floating point performance. Which didn't matter until the Pentium's reigned the market with their integrated FP-coprocessors after it became clear that 486DX sold a lot better than their FP-less counterparts 486SX.

          RISCOS was (maybe still is) assembler-optimised which is the reason for it's performance. The same with current Nokia cellphones. Symbian is the most optimised ARM-platform to date hence the reason why Nokia can still use olde ARM11 cores and still get very decent performance out of them. I'm let to believe that Windows Phone 7 OS is also quite optimised (it should be if you consider how long M$ have used ARM-code/cpus).

          1. James Hughes 1


            The Nokia N8 can do 720p encode because it uses a Videocore 3 GPU - the predecessor to the Videocore 4 GPU in the Raspberry Pi.

        That's presumably because either you have a seriously powerful CPU that can decode video in software or you don't realise that your "open" Linux box is running a pile of closed proprietary binary code which the graphics card manufacturer has provided to support the minimum functionality that can be labelled "Linux video acceleration".

        I'm afraid most Linux boxes aren't going to get very far with video that doesn't conform to the lowest common denominator of what VA API and VDPAU can support - provided that the graphics card offers even that. And anyone not using X is mostly SOL. There's specifically not (yet) any documentation I can find about whether the GPU blob for this platform supports either VA API or VDPAU (which would be a start) or whether it provides for video decoding and presentation that would work without X (for example directFB).

                What do you mean, "driver source"?

                What such vendors do is provide a "blob" of executable code, possibly entirely proprietary firmware to load onto the card, and perhaps a shim to stick it where it needs to go. Sometimes that shim is written by some linux hacker and thus GPL and then it might be loading some binary filched from the windows driver distribution instead of anything "official".

                That shim is the only bit you'd get to see the source for and isn't particularly helpful in fixing anything, nevermind writing your own. It's one of those things that sets the "tainted" flag on the kernel, and oftentimes won't on anything non-x86, or on the wrong version of the vendor-blessed linux distribution, or.... Vendors acting like linux can be supplied with drivers like it was windows. It's a bit of a mess, it is.

                Of course, there do exist vendors that do supply open drivers for their hardware, and sometimes they're even decent to good. But those are few and far between. Most vendors and for that matter most of us are usually better off with the specifications published free-for-all; someone'll pick up the specs and write the driver for their pet OS. But of course with the increased threat of patent abuse there's a perverse incentive to make a pheripheral and then not tell anyone how to talk to it. Then again it does help if people contact vendors and ask for programming specs. If enough people ask for them, then more and more vendors will release them.

          The proprietary binary code blobs i've used on a number of Linux boxes have provided an awful lot more than 'the minimum functionality that can be labelled "Linux video acceleration"' - don't be such a troll. There is a noticable, sometimes very large, gap in performance between, e.g. the AMD/ATi Linux and Windows drivers, in a number of areas - to be expected given the economics - but they are far from minimum functionality. The gap is also closing in some places, all from the same vendor.

      Videocore IV supports H264 High profile 1080p30, along with MP4. However, those codecs that need an expensive licence won't be suppled. Don't blame the Raspberry Pi, blame the licence cost. Interestingly AAC is the highest codec cost of the lot, and yet is the simplest format.

    I hope this does well..

    Consider for a moment that this hardware is perfectly capable of running a typical "office" application set, and there may be some serious interest from corporate purchasers - £200 a head for a PC, or £25 for this? (By way of a supporting argument, Microsoft are currently porting Microsoft Office to Nokia's Symbian3 phones which use a very similar hardware configuration). In these times of cutbacks, these would also make good student workstations for colleges - especially if you want to teach embedded and mobile development.

    Raspberry Pi also has Qt available for application development, which gets over the big hurdle of modern systems: how do you start coding if you don't know how to code. Qt Quick is a great way to ease into programming - like HTML, it's pretty easy to get something that moves and reacts, and for simple control you can use snippets of JavaScript... but then there's a full native-code object-oriented MVC architecture underneath for more demanding tasks, and if that's too limiting, you can delve deeper again and get into low-level system calls, all in the same runtime.

    Also a bit of a pity the graphics chip is closed up, someone really needs to whack broadcom over the head for being so annoyingly secretive. But at least the mobile opengl is something. Now for opencl on that same hardware.

    Thing is, the ability to stick something in your pocket that's a (near enough) complete environment to do some task is actually quite powerful, moreso than I expected. Even if you can't take the display with you also. We possibly might see the revival of a c64/bbc/amiga-esque "scene".

    On the other hand, though, I'm seriously looking at acquiring some new, much faster kit to give me back a good development environment and a bit of oomph for running data analysis and such. Part of the price (some 500-odd ukp projected and damn those floods) is virtualisation support (with x86's notoriously poor historical support and architectural supportability that's noticeable, yes) so as to run various "OS containers" concurrently. I think that'll stay too, as sometimes the oomph and convenience of not having to swap out devices on the telly is worth something too. Now for some way to migrate those things back and forth from the cloud or even say a friendly local organisation's handy K super clone for real computation, to the desktop to keep it all in hand, to the laptop to keep tinkering abroad, and back again, preferrably seamlessly. There's much to innovate yet.

    * The stanford online classes, all three of them. I really should stop slacking off.

    ** It could do flash with suitable emulation installed, but I opted for trying the different stick method instead.

    All this talk of tweeting, web browsing, linux nonsense - kids already have that crap on the PCs, why make this thing do all that?

    Machines like the speccy and C64 inspired people because you turn it on and type some BASIC and things happened on screen. When you got the hang of it you move on to machine code and do better things.

    Let this thing boot into a simple editor with a simple language and an assembler. If you're new to coding, I don't think trying to use an OpenGL library is going to be much fun. That comes later, and all this HTML and javascript nonsense - just use a PC.

      Unfortunatly ppl demand some form of basic usability (which include websurfing).

      On RISCOS you simply press F12 to get to a CLI. From there you type 'BASIC' to revoke the BBC Basic interpreter and from withing that BASIC you use [ ] (square brackets) to insert your Assembler code. Neat and easy :-)

      The IMHO very best example of this kind of programming is the program Architec which was written in Basis/Basic-assembler. It was a real time 3D modelling package with real time texture mapping etc...

      I've seen it's code. Not that I could do what these guys had done (I think it was Aspex Software from the UK whom made it) but it showed what could be done in these systems using the inbuild BASIC/Assembler tools.

    Impressive feat of engineering, and I really hope it will be successful and help kids get into computing. Especially those who might not have any other chance.

    I am a bit dubious though. How many people is it going to help?

    People on this forum could just buy one for £20 and probably have enough spare kit to build a system.

    For a household which doesn't already have a computer, in addition to the RPi they also need to buy a keyboard, mouse, USB hub, cables, power supply, SD card and probably a monitor. Starts to make a second hand laptop look more attractive. But they could have done that already, and haven't.

    Then they need an internet connection as well, most likely.

    For kids who already have access to a computer, what aspect of the RPi is going to inspire them to program? It's just a linux box. They will use it to go on Facebook.

    I don't want to be negative. Its small form factor could make it a more sophisticated arduino. Maybe some schools will use it to kit out a computer lab with a private network.

    Good luck to them though. It could be a game changer in the third world.

      Thrid world home computers

      I think the third world market is pretty well sewn up at the moment with keyboard equipped "Famiclones" - a copy of an 8-bit Nintendo system with BASIC, word processor and some educational software in ROM. These things come in many (hundreds of) different shapes and sizes and are churned out in huge quantities by many Chinese factories, and seem to retail at about $10 to the end user. There is a volunteer project to improve the quality of the software that gets bundled with them called PlayPower:

      For a similar sort of outlay to the Raspberry Pi, in the first world one can buy a Chumby One/Insignia Infocast which is an ARM based SoC equipped console with 3.5" touchscreen, built in WiFi and USB host. It runs a Macromedia Flash implementation on top of the Linux kernel, but it has been designed to be easy to get a remote console and do more interesting stuff with. It's obviously not as powerful as the Pi though, and lacks it's more sophisticated video capabilities.

      Not quite.

      Most reasonably modern tv sets have hdmi. A cheap mouse plus keyboard plus usb hub can be had for (looks up skinflint... 1.5+2+1 =) less than a fiver if you're lucky. Might already have a spare hdmi and/or usb cable, recent phones already get charged through mini-usb and thus come with a suitable wall-wart, and perhaps you can filch the old card plus microsd-to-sd adapter from a friendly nearby member of the family who recently upgraded the microsd in his phone. There's quite a bit of likely leeway there.

      The big attraction is that it's not the family computer, but something you can drop in your pocket and use wherever there's a suitable telly to be monopolised. It's a great excuse to be doing "something educational" instead of watching cartoons or something, so sellable to the parents too. Schools need only bolt hdmi-equipped screens and usb keyboards+mice to the desks in the classroom (might even see them back integrated, how's that for a throwback?) and the kids will provide their own computing power and storage. It's theirs, they take it with them, and it'll work the same wherever they are. Newer versions will be brought in with newer classes, saving a lot of trouble upgrading -- presumably hdmi and usb will last a while.

      Honestly, I think it's underfunded schools and the underclasses 'round here that'll benefit much more easily than the throwaway charitable goal of "the third world". You'd have to build a power grid there first, for one, and the tellies will be CRT type and will not have hdmi, for another. In fact power even to recharge mobiles there is often a couple hours walking away. An olpc with a humongous battery is what you'd need there. Forget about the third world. This thing is great for here, for getting more kids hooked on making things happen themselves, and through that get them interested in engineering. Which pretty much was the goal.

    Hobbyist machine, not a revolution, ffs

    Come on people, this is 2011, not 1981. The "nightmare of frameworks and compilers" is what allows 90% of developers to earn a living programming. They neither need nor want to run "on the metal", or write "tight code". And neither should they; the democratisation of software authorship is predicated on machines having the power to run high-level systems and languages. This idea goes against that, and harks back to a time 30 years ago when only nerds programmed. It's a piece of nostalgia, plain and simple.

    In case you guys haven't noticed, the marketability of low-level coding skills is diminishing year on year, and has been for over a decade. Sorry, but you don't expand the workforce to become coders by propagating an 80s myth about the level of elite skills required for the job, and going on about "coding to the metal" or how we did things when we were lads. Jesus. You may as well try to expand mining in this country by teaching kids to swing a pick-axe.

    It's nice to have a cheap Linux board, but it's not exactly a revolutionary idea, and if cheap Linux boards are so desirable why weren't schools buying them in their millions at the £60 price point? We're being asked to believe this is a revolution, but the truth of that has to be based on there being this immense price sensitivity in the market, which doesn't seem likely given that the prices of bare-board systems have been dropping steadily for the last 10 years and they are still just hobbyist items. Is the next 50% discount really going to make them suddenly go mainstream?

    I can't be the only person who thinks the hype around this is ridiculous, can I? Computers are all about SOFTWARE, it is software which makes them flexible, it is software where the cool stuff is happening that's relevant to a maturing market, and that software is becoming better because it leans on other software. And yet everyone creams their pants when a new piece of hardware comes out that is identical to a hundred other pieces of hardware, but at a somewhat lower price point. It's staggering.

    Here's an idea - if you want kids to learn programming, demand they are given programming courses at school, on the existing kit. Create a demand for simpler development environments. And start by looking at what we already have - Javascript in the browser is an easy way for anyone to get started. You can begin simple and build up, it's a high-level language, it works, it's safe, it's sandboxed, it's fast compared to even the best 8-bit machines, it has its own sprite engine and lately its own 3D layer, and you don't have to buy any new hardware. Most importantly, it's a still-relevant skill, and will likely outlast the current generation of secondary school kids by some time.

    Expecting to be downvoted for this, don't worry :) You do what you have to do :)

    1. James Hughes 1

      Way to miss the point

      In school they are NOT ALLOWED to program the machine in case they bugger them up. They are an expensive resource that need to be maintained.

      This device give them the ability to bugger it up to their hearts content. You just need to re-image the SD card and you are back to square one. No IT support needed. And even if you somehow break the hardware - its $35 so not going to break the bank.

      You are right - it is just another Linux board. But it's CHEAP and therefore more accessible. But because its JALB (c) it can run almost any language you want for free. Unlike all those school computers running Windows. And there is the software angle. Yes, its all down to the software, but you need a device to write software on, and this is a good one.

      And I think you are wrong about the market for low level coding skills declining. We are constantly needing low level coders, and there simply are not enough good ones. There is a constant demand for software for low level devices as so much stuff has some sort of SW requirement nowadays. There is also the fact that a good low level coder is generally better at high level coding and debugging because they have a better understanding of how the device works under the skin. A low level coder can work at the high level. Not the other way round.

      @Eddie Edwards:

      "Come on people, this is 2011, not 1981. The "nightmare of frameworks and compilers" is what allows 90% of developers to earn a living programming."

      You don't become a successful civil engineer or architect by being ignorant of basic materials science. Knowing the acceptable loading factors and stress ranges is kind of crucial: get it wrong and your building will fall down. You can delegate this low-level work once you've reached the heady heights of building major skyscrapers, but understanding the basic foundational elements of your line of work is most emphatically not optional.

      Programming is the same: there's a big difference between knowing a handful of APIs, and knowing how a computer actually *works*. And the only certain way to learn the latter is to try doing it. In a low-level language like assembly language, or C. (I'm not aware of any CPUs that can do OOP at the assembly language level, so procedural it is.)

      Knowing how a computer "thinks" is the only way to really understand programming at a deep level. It helps no end in debugging. It also comes in handy if you have to code for constrained platforms and embedded devices, as well as in situations where optimisation skills are useful. (E.g. in game development.)

      "Javascript in the browser is an easy way for anyone to get started."

      If you'd suggested an environment like Unity (, I'd agree with you, but JS in a *browser*? Seriously?

      Leaving aside the fact that Javascript is a language that has had everything and the kitchen sink nailed onto it—procedural, OO, functional; you name it—so it's not as simple to pick up as you imply, you then have the problem that in-browser Javascript pretty much requires HTML (and CSS, to at least some extent) as well if they're going to get any decent user interaction and interface design done.

      And that's before we get onto the subject of browser compatibility. Not every browser on every platform supports every Javascript feature. Especially if it's an older browser. Schools are notorious for not upgrading their computer labs very often: they don't have a lot of money to play with.

      Even at £20 you still need a display unless you're doing the kind of low-level stuff that you've already told us is unnecessary. So the cost is dominated by the display, anyway. Of course, there are likely to be lots of schools who are awash with kit and who would perhaps welcome this kind of thing as a discount, but then there are plenty of other reasons why they wouldn't go for it: demand that "business skills" be taught is the primary one, and the one which this initiative is trying to overturn. But apart from schools, this initiative is trying to make stuff more affordable for home use. There, with an existing display, a drop from £60 to £20 is quite something.

      "Here's an idea - if you want kids to learn programming, demand they are given programming courses at school, on the existing kit."

      This is already going on. Unfortunately, the environments are evolving to *avoid* teaching the basics. Not having to worry about how you represent numbers, say, isn't such a bad thing - we all prefer working with abstractions instead of worrying about the details - but there's a tendency for "junior programming" environments to become nothing more than animation software, and then the fundamental skills aren't learned properly by the pupils. Fancy animations and trial and error fill in for actual understanding.

      I kind of agree with what you're arguing, at least around the hardware. I think some of the people involved have a fetish for the microcomputer era (with all the "Model A" and "Model B" non-originality), but then I think that they betray the spirit of that era by wanting to deliver a tools platform with many of the innards cordoned off: read the Partis thread with Alan Cox's comments for an indication of this. If they don't even expose the same stuff that you could play with in the early ARM computers, where the average person didn't even get to tinker as much as they did on the Beeb, then your arguments are strengthened somewhat and this looks a bit more like a vanity project.

      1. bhtooefr

        The display can be a junk (donated) CRT TV, though, so not exactly expensive.

        At least in the US, free or very cheap CRT TVs are a dime a dozen, because of the digital TV mandate here.

      It's a board with a collection of digital I/O lines that you can interface homebrew electronics to. A PC is notably lacking in this department. You used to be able to bodge some things onto a parallel port, but now PCs don't have a parallel port. Otherwise you choose between USB (too complex) or buying a digital I/O card (not cheap, especially if it's a notebook PC rather than a desktop).

    I think you mean 720MHz Mr Writer!

    Both products are great in their own way, BeagleBone has a powerful general core with a NEON vector processor and lots of low-level I/O functionality that you'd normally have to use an intermediary chip for like PWM, ADC etc. The chip is commercially available and the design is simple and so easy to produce custom models. The unit is designed to be expanded.

    RaspberryPi is cheap but difficult to reproduce for commercial purposes (cpu can only be purchased in whopping quantities and stacked memory is difficult to manufacture). On the other hand whilst the main CPU is a bit weak it has a very powerful graphics core + DSP and so some dedicated time on coding for it could yield surprising performance. Also has HDMI out. It's more of an Application processor like what you'd expect to find in a smartphone (was originally designed for camcorders).

    not-for-profit cutout of Broadcom

    Follow the money.. Founder of RaspberryPi, Eben Upton, told slashdot..

    "our dream scenario is that someone in China decides to copy our design and start knocking out millions of clones. Remember we’re a not-for-profit organization under English law, and all our trustees have other jobs".

    Indeed! For his day job, Eben in an executive at Broadcom. The firmly closed source Corporation will be in a dream situation if Chinese cloners take the bait.

    There are plenty of better development boards than this one. Some may not be quite so cheap, like the boards based on the MIPS-compatible Loongson CPU, but you do get you what pay for.

    P.S. It's distinctly bad P.R. (and poor etiquette) to close a forum thread rather than use the focus to defend your decisions. Is that going to happen every time someone questions the RaspberryPi Foundation?

    1. Nigel 11

      Point me at a better alternative

      Show me a developer board with decent display capability and audio, a network port, and USB, that runs a well-known Linux distribution, out of the box and usably fast, for less than twice this price.

      The plug-computing things like pogo-plug and guru-plug missed the mark by not having any AV or accessible user-hackable IO lines. (They also ran too hot).

      I expect if RasberryPi shows any sign of taking off, there will be "me too" products soon enough!

      1. bhtooefr

        Well, that's not the parent's argument, that it's bad value for money or anything like that.

        The parent's argument is that Raspberry Pi is a Broadcom shell company, and Broadcom actually wants Chinese cloners, because they have to buy the Broadcom chip to clone it.

        The thing is, unless these things are being sold for a loss, I'm not seeing the problem even if all of that is true. What's important has either been documented, is readable from source code, or is in a binary blob that's available to ALL OSes (IIRC, the GPU's binary blob runs on the GPU, and the GPU actually can take OpenGL instructions natively with that blob, so the "driver" is an open source stub that feeds the instructions to the GPU side of the device), is my understanding.

        1. James Hughes 1

          Not a shell company..

          Raspberry Pi is an independent charity, that is using Broadcom chip. They use the Broadcom chip because Eben knows its capabilities and the foundation gets a discount.

          The Raspberry Pi is sold at just over cost, making just enough cash to run the foundation.

    2. James Hughes 1


      Couple of corrections to your post.

      Eben is NOT an executive at Broadcom.

      The Foundation as far as I know hasn't closed any threads on their forum without discussion. I think one was closed because it was degenerating in to a round the houses repeating thread, as often happens with these OSS arguments. They have welcomed comments, and put forward counterarguments. To me it seems that the more militaristic OSS advocates are entirely unable to acept even an iotas difference from their strict worldview - taking on for example, a bit of pragmatism.

      Broadcom have donated time and money to this project, to no real gain (they are not selling enough chips to Raspberry Pi to make back the money). If they make a few quid on the back of Chinese sales, where is the problem? After all, they are a publicly listed company that needs to pay its employees.

  34. DasEnglander

    "Startled" is not how I would have described the reaction of the open source Nazi's. Many of whom have been quite vocal in their condemnation of the foundation for things which are, quite frankly, way beyond their control.

            The problem is one of perception. People hear 'open source' and they automatically think of the very vocal minority I was referring to. It simply doesn't occur to them that the vastly larger majority of the 'community' might not share this obsession.

            Probably because we don't leap up and down, screaming and shouting every time the subject comes up.

      broadcom: open source parasite

      "In Alan [Cox]'s case he does seem to understand that some things are not under their control. He simply refuses to accept it doesn't actually matter to the target audience."

      Since the RaspberryPi is to serve as an educational aid, it matters *very much* that the kernel device driver for a major component on the board is strictly closed source.

      The very involvement of Broadcom leaves a bad taste. The Corporation has a contemptuous attitude towards the Open Source Software community. Yet, perversely, it is one of the greatest beneficiaries of OSS and the benevolence of others who generously grant a GPL to their own source code.

      In terms of OSS, Broadcom Corp is much more the parasite than the patron.

      By way of example:

      Most, if not all of today's routers (and DSLAMs?...) based on Broadcom chipsets, are running MIPS Linux. In the userspace, tools including iptables, ebtables and busybox are found. This is all GPL'ed open source software. Not that you would know it from Broadcom's attitude.

      It took years of legal threats and arguments before *our* GPL'ed source code that had been modified by Broadcom for those chipsets was to see the light of day. See the case of The Software Freedom Law Center (SFLC) v Verizon Communications Inc.

      It is because of that attitude, that many will instinctively frown at Broadcom's involvement in this project. And the fact that the RaspberryPi device serves as a vehicle for Broadcom to gain a foothold in our classrooms must also raise eyebrows in academia.

      We know from the Great Academic Sell-out to Microsoft (not least in Cambridge) that the quality and scope of teaching invariably suffers when corporate invasions of our classrooms are left unchecked and unchallenged. If a company wants to reach our young scholars with its proprietary products then it must play by our rules. The minimal obligation is to release all necessary source code.

      On a technical point, those with experience in building Linux kernels will instantly recognise the major problems of blob driver code. Most of us have our own personal graveyards of equipment that was sold, like the RaspberryPi, with binary-only kernel driver code.

      Those devices became redundant not because of technical obsolescence, but simply because the manufacturer stopped production and soon thereafter, abandoned the release of new drivers. With no source code for the Community to continue its own driver development, the devices soon fail to function with up-to-date operating systems. Outcome? A trip to the landfill.

      "Personally, I think the foundation's staff and forum moderators have been incredibly patient with these people. I would have wielded the mighty banhammer against the worst offenders long before now."


      With the Official RaspberryPi Forum now safely under control, the Rapid Rebuttal Unit of RaspberryPi has moved on to other internet forums, like this one, to continue the perception management of the project and its relationship with the Broadcom Corporation (market capitalisation today of $16.3bn).

    exactly what I'm looking for

    A small, cheap, ARM-based computer with ethernet and at least 1 USB. If they actually go on sale for £22 then I shall be wanting at least 5 to run some tests. I am interested in how I might be able to use hundreds of cheap solid state computers + cheap solid state flash memory to build a search engine.

    Google's real brainwave was buying the cheapest commodity computers and learning how to thrash them for all they were worth. But now their architecture is too big and clumsy to run on these new low-power computers that are emerging. I see a gap in the market.

    My idea is to focus all the intelligent logic on the communication between nodes, with the nodes themselves being fairly stupid web crawling and file sharing machines with a fairly narrow sphere of influence. The challenge is to devise a set of rules by which these stupid nodes could, as a collective, do something useful. With massive power efficiency compared to conventional search engine models.

    And at the end of the day, even if it takes me 15 minutes to run one search, in many cases I would rather wait than give more of my privacy to Google. In other words, even if my search engine sucks something fierce, I will still enjoy using it.

    Binary Blobs

    My understanding (and I very-much welcome correction if I am wrong) is that the BeagleBoard's graphics is completely unaccelerated under Linux as the drivers are simply not released in any form. This has been the show-stopper for me on this platform, which I am otherwise very keen on.

    With the RaspberryPi, there is a binary driver, at least. I personally have no interest or ability to do anything on that level, so for me as long as there is an open API, I am likely to be happy enough.

    Will be watching this eagerly for classroom use applications.

    1. Neil 7


      The OMAP processor uses PowerVR for it's GPU and the drivers for this line of GPU have never been released as open source, or even binary blob - only the hardware vendor can supply the drivers as part of a complete, finished product (including OS etc.) which isn't really what the Beagleboard/bone is about.

      I try to avoid any hardware that contains PowerVR which is why I'm quite keen to see more SoCs coming to market (mainly so far from Samsung) with Mali GPUs as these are fully open source compliant (thanks ARM!)

      In order for Broadcom to do the work (and they are the only people who could - the GPU needs specialist knowledge and compilers which are not available outside the Cambridge office), there would need to be some profit motive, and there doesn't appear to be one at the moment.

    Pi in the sky

    It's a laudable objective. But as the article observes, who is going to teach these skills. Many 'ICT' teachers can just about show kids who to use Excel and Word. Is hacking a system in the skill set of any UK teachers?

    It'll be interesting to see if the DoE has *any* interest. Aside from the dearth of teachers I'm sure HM Constabularies are going to be delighted they can look forward to a new generation of hackers in a few year time and will be lobbying accordingly.

    To me learning to program is learning to use a tool like learning to drive or use a hammer. Not an end in itself. If it is the end, where are the jobs for this mass of kids? These days the grunt work of programming is done in India and China. Maybe there are a few specialists here and there and Uni CS departments will need a handful post-grads.

    As an unrepresentative statistic we have a household stuffed to the gunnels with PCs with which which our boys can do what they please and the resources around them to learn about the innards of PCs and operating systems. Do they choose to hack and program? No. It's way too hard and there's too much else to do. The first thing any kid wants to do is develop COD and, at least in the case of my kids, were turned off the whole idea of programming when it became apparent just how hard that is.

    For kids brought up with Windows even getting to a command prompt, much less hack a system, is an unwelcome experience.

    So I applaud the Raspberry Pi initiative and I look forward to getting and using some of the devices. It's like reliving a youth, Z80 redux. And anyway I can think of loads of uses for a fleet of inexpensive headless devices like these. But I am not convinced of the case for the stated direction of the project.

    "it became too expensive to give kids a simple computer to toy with"?

    Rubbish. Back in 1984 my parents bought an Amstrad CPC 464 for me and my sister. It cost 400 quid and came with a monitor. That's about the same as a grand these days, for which you can buy *two* cheap Dells, with monitors.

    No, the problem of kids not having simple computers to play with isn't cost, it's that users aren't forced straight into a programming environment, which makes it more difficult to just play with the damned thing and see what you can make it do.

    A side issue is that families these days appear to be addicted to the telly, and so kids can't unplug the idiot box to use it as a monitor. There's no technical barriers to doing this - lots of modern digital TVs have VGA ports, and DVI-to-HDMI converters are common.

      So, basically a Nokia N8 without the touchscreen.

      Windows 8 will most likely only run on ARMv7 and above, so possibly Cortex-A8 (Beagleboard/Beaglebone) but more likely Cortex-A9. Although it wouldn't surprise me if Microsoft only support Qualcomm SoCs initially.

        Our Microsoft rep did mention in passing that they have no plans to support Broadcom SoCs. He wouldn't or couldn't go into detail but did mention "open source issues".

        It seems that Broadcom are damned if they do and damned if they don't.

        Some of the open source Nazis scream abuse at them because they won't open source their extremely valuable IP. Others scream abuse at them because some of their customers have violated the GPL.

        And then, to add insult to injury. Microsoft - probably the worst offender of the lot when it comes to 'misappropriating' open source code - won't support their SoCs because of unspecified "open source issues".

        Of course the latter could simply be the usual sales rep 'in the know' horse manure of which we have all seen far too much...

          @DasEnglander - re Lack of Broadcom support

          As with their smartphone OS, I very much doubt MIcrosoft wants to find itself having to support more than one or two ARM SoCs. Maybe there really are "open source" issues with Broadcom SoCs (although this hasn't exactly held back various Linux distributions as evidenced by the Pi) so it does sound like spin from the MS rep - anything to shift the blame rather than admit MS don't want/aren't capable of supporting multiple ARM platforms, and would rather support a limited number of "anointed" companies, eg. Qualcomm initially, but eventually ST-Ericsson through Nokia's involvement with WP7 and trying to create a (price) competitive hardware ecosystem.

    It's all in the documentation.

    The problem I see with the RaspPi is not with the hardware, or even the software, such as it is. No, it's the lack of a single, bound, dead-tree manual, as they had originally envisaged, but dropped.

    You see, the reason for the burgeoning of the programming teens in the early '80s only had relatively little to do with the actual hardware (other than the ability to annoy their parents with stupid noises within 5 minutes or annoying their sister by plastering their "boyfriend"'s name on the screen in multi-colours) but all to do with the excellent manuals which came with the devices. These lead the user through the basics of BASIC and on without talking down to them. They also had the teasing technical information at the end, which acted as a goal to understand.

    Now, if you look at the late '80s, even the ZX Spectrum had lost its programming manual and what came with it was little more than a pamphlet telling you how to load a game. The bedroom coders stopped being inspired. The hardware hadn't changed, only the documentation had.

    So, in my opinion, it would be far better for the Raspberry Pi Foundation to get a good manual writer on board, make the default boot environment a stripped down Linux kernel with a BASIC or other interpreter directly on top (which has to have simple sound creation and sister annoying ability within 5 minutes) and sell the thing as a bundle. Possibly sell the book with the hardware as a freebie which comes with it.

    As much as I would like to see the Pi promote programming education, I haven't seen the killer argument for it yet.

    All schools have computers these days; what will the Pi do that they couldn't already do with their existing computers? Cost is not an issue - they already have perfectly adequate programming platforms sat in their ICT suites. Security? I don't believe it is beyond the wit of man to come up with a secure educational programming environment. If it doesn't already exist.

    If there really was a demand for it, I'm sure there would be some enterprising company happy to supply a cheap and secure programming environment for schools. In fact there already is, for example Scratch from MIT which is free. It's a great tool aimed at kids for learning to program. My son loves it. So I showed him Eclipse. He ran a mile!

    So if its not cost or security, what is it? Hard work? Concentration?None instant gratification? Something not related to celebrity culture? If Cheryl Cole or David Beckham started to program, you can bet your bottom dollar the kids would be doing it like its going out of fashion.

    The Pi will be a game changer, IMO. But not in the education sector.

    Considering that CRT monitors can be got hold of dirt cheap (or free) nowadays, which would obviously make the total outlay more acceptable to poorer people/schools who might benefit from these, and most LCD TV's have a VGA input, it seems a shame that they didn't fit these with VGA rather than HDMI :(
