Eben Upton Answers Your Questions

Education 37

Last week you asked the Director of the Raspberry Pi Foundation, Eben Upton, about developing an ultra-low-cost computer and running a charitable organization. Below you'll find his answers. Thanks go out to a busy Eben for responding so quickly.The role of commercial viability in education
by ronocdh

Your decision to sell the Raspberry Pi to any interested parties, not just educational institutions, seems to indicate a broad-minded approach to education, favoring transparency and open standards. What percentage of your costs do you expect to cover by selling directly to individual, hacker-type enthusiasts, versus wholesale distribution to educational institutions for inclusion in curricula?

Eben: Initially, we expect to sell almost all of our output to the hobbyist community. Our revenue models assume a roughly 50-50 mix of in-house and wholesale distribution (education and resellers) after the first year. We have a very low fixed-cost base, and will break even when we reach sales of 20-30k units per year.

One reason we’re also selling to individuals is that we believe very strongly in self-directed learning. I didn’t learn to program in a classroom; I did it by hacking on the school computers in my own time and subsequently buying a second-hand machine of my own (after saving for what seemed at the time like an eon). While there are many teachers out there who have the necessary skills to teach computer science, we realize that a large number of pupils will never encounter one of these teachers, and that the subject is generally absent from standardized curricula.

It is likely that more children will learn programming by using Raspberry Pi at home than in school. We’re investigating the possibility of establishing a prize fund to reward children who develop exceptional software under their own steam.

Power Supply
by Anonymous Coward

The requirement for an external power supply seems unfortunate given the small form factor of the computer. When so many devices can draw power from a USB port (and yes, I do acknowledge that these are USB peripherals whereas the Raspberry Pi is a USB host), the need for another cable on such a small device is probably going to be an inconvenience. I'm sure that this is a topic that generated some interesting engineering discussions during product development. Can you share with us what other alternatives may have been considered and the pros and cons of them, and how you ultimately concluded that an external power supply is necessary? 1W at 5V is 200mA, which is certainly a plausible amount of current to draw from a USB cable. It could even make sense for the Raspberry Pi to be a USB device and host a telnet server. Was this use case considered?

Eben: As it happens, the tiny USB-key form factor that David shows in the original BBC video is powered by a hacked USB hub which emits power on its host port. We focused on the USB host use case, because we see Raspberry Pi primarily as computer rather than as a peripheral, and because doing so keeps the cost and complexity of the board itself to a minimum.

We want to find a way to eliminate the power supply for some users, and hope to support a power over Ethernet module as an option at some point if there’s sufficient demand; right now our low-cost RJ-45 jack is not PoE-capable, but this will probably change.

VGA?
by ajo_arctus

I think it's an incredible project, and I'll certainly buy one for my son when they come out. I'm just wondering though if not having VGA is a bit of an oversight and I'd be interested to know why you made that tradeoff. I agree composite is great for places where old TVs are common, and HDMI is great for those of us who just want it as a novelty, it's just I can't help but feel that the people who could benefit most from this would most likely get one of these along with a free or very low cost second-hand monitor, which would almost certainly be VGA only.

Eben: The tradeoff is driven by the feature set of the BCM2835. Previous products in this line used an analog RGB TV output peripheral which could be hacked to drive VGA quite easily; irritatingly, for cost reasons, BCM2835 only supports single-channel (composite) video out, which prevents us from doing this.

I agree that the lack of VGA output is a very significant problem with the device, particularly in school environments, where (at least in the UK) there are often labs full of old analog monitors. Although we can’t afford to add chips to the baseline device to support it, we’re investigating three routes to add VGA compatibility in the future:

Supporting monochrome output directly using our single-channel analog TV interface.
Bridging from the HDMI/DVI output to VGA using an add-on board or “smart cable”.
Bridging from the onboard MIPI DSI interface in the same way.

This is right at the top of our follow-on project list, once the main boards are out of the door.

More enbedded features?
by Anonymous Coward

Love the concept, and will probably buy at least a couple of the model B.

I was wondering if you plan to have future models with more embedded features (like Bluetooth, WiFi, and GPS)? I know this would raise the cost, but with smartphones including all those things, I wouldn't think that it would be too expensive.

Great work, can't wait to pick mine up.


Eben: Glad to hear you like the concept. We’re investigating the possibility of adding exactly the three interfaces you mention to a future version. These are available in quite cost-effective “combo chips” from a number of manufacturers, and it may be that savings from removing the Ethernet bridge chip, transformers and RJ-45 jack will go some way towards paying for the extra silicon.

FCC (and equivalent) certification of a wireless-capable version would be challenging for us with our current level of staffing, but hopefully this will change as we start to sell the Model A and B devices.

Open Sourced Schematics and Layout?
by Anonymous Coward

Are you going to open source the schematics and layout for the hardware design?If so, will they be provided in formats that are easy to use with low cost and / or free software tools such as Eagle, KiCad, or gEDA?

Eben: A qualified yes. We intend to release our schematics and board designs provided we are satisfied that the chips needed to build the device are available through distribution in reasonably small quantities. Our relationships with our component vendors are critical to the success of Raspberry Pi; we wouldn’t want to put them in a position where they were being criticized for being unwilling to provide chips directly to hobbyists.

If we do open the hardware, we’ll use a format compatible with a cheap package (Eagle would be my preference, although we’d need to check the limitations in the free version). We very much hope to be able to do this. We’ve said elsewhere that 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, so we don’t have the same set of incentives as a regular company.

A cautionary note for people hoping to build these devices themselves – I don’t believe it’s feasible to assemble it manually, and the PoP memory configuration we use is beyond the reach even of some professional assembly houses.

parallel computing
by jtollefson

Since the price point on these are so low, what's the feasibility of doing mass grid computing on these machines?

Eben: I think it’s very feasible, though I have my doubts as to whether Raspberry Pi is a particularly good source of cheap MIPS. Consider that only a small fraction of our die area is occupied by the ARM core, so if you’re intending to just do CPU work you’re carrying a lot of baggage (GPU, video accelerator, camera pipeline, JPEG codec, a couple of DSPs) which isn’t being used. We’d need to run the numbers, but I expect that a $200 x86 box will give you more compute than 8 Raspberry Pis, and in a more friendly package (a two or four concurrent threads, rather than eight).

Where we may come into our own is in providing low-energy MIPS. Idle-time distributed computing applications like Folding@Home should work, and you wouldn’t need to worry about justifying the power consumption of a PC.

Java development?
by eparker05

Since the primary OS will be Debian based we can assume support for C, C++, Python, Perl, and Bash scripting. But I have heard that you would need to get Oracle involved if you wanted a Java SE JDK since the RPi is Arm based. Can you comment on whether or not this is true and, if so, have you or are you in the process of obtaining the ability to develop Java on this platform?

Eben: We’ve not looked into Java support in detail, and certainly haven’t been in touch with Oracle. Various people have suggested OpenJDK to us as a good alternative; it’s known to work well on ARM-based systems, and doesn’t require us to obtain a license.

Can You Extrapolate on Your Teaching Strategy?
by eldavojohn

I see that you plan on using C and Python for teaching languages. I recognize that I am of an older generation but grasping C in its entirety or even little endian versus big endian was something that didn't fully come around until college for me. What are your strategies for teaching even younger targets with something like C (Python, however is probably easier)? Are you developing a rigid teaching course line or just happy to have the community put anything out? Furthermore, what is the point of putting all these other languages on your wiki like Processing or Lua? Could you or someone on your staff give a brief explanation for each of these links or are they here just to inspire someone to write a tutorial for -- I don't know -- harvesting data with the Raspberry Pi and displaying it in Processing on another computer? Or do you intend the processing application to compile to ARMv6 on the device and run on the device for a UI output? I know ARMv6 is supposed to be a leaner architecture but I'm not at all familiar with the Broadcom BCM2835 that you've shown on your alpha boards. All my searches for it just link back to your site.

Eben: We’re very happy for the community to put anything out there; originally we’d planned to provide an integrated teaching curriculum built around the device, but it\s become clear that there are a lot of third parties out there with much more experience than us. The wiki is a good example – it was set up by someone else, and we have very little to do with it. I’m personally a fan of putting Lua on the device, because it leads in nicely to things like Garry’s mod programming on the PC; we’ve supplied an alpha board to a Cambridge-area developer who is working on a Lua port.

BCM2835 is a new application processor, derived from the BCM2763 graphics processor, which does get a mention on the Broadcom web site. Most applications are likely to run on the device with local UI output, though there have been people on our forums talking about using them for remote data logging.

Introduction to programming
by simonloach

The raspberry pi is meant to introduce programming concepts to school-level children.

My question is: How are you planning on doing this from a UI perspective? The BBC micro (as far as I can tell, a little before my time) simply dropped the user into a BASIC prompt and left the rest to their imagination. This seems like a pretty fundamental design question for the raspberry pi, but I haven't been able to find a clear answer yet.


Eben: If it were up to us, we’d probably just drop people into a bash (or even better, IPython) shell and let them get on with it. On the other hand, there are many people who just want to use the Raspberry Pi as a general-purpose productivity machine; for these people, we’ll need to provide a desktop environment as an option in the standard root filesystem.

I think the compromise is likely to be that we boot to a bash shell, and require the user to type ‘startx’ to get a desktop, or ‘python’ (or whatever) to start programming. Don’t expect to see a standard install boot to gdm. Because we’re nostalgic old farts, we’re also looking at making sure there’s a way for you to boot the board straight into BASIC.

It's all about the manuals
by MROD

Seeing as the aim of the project is to create a tinkering platform for nascent, teenage programmers I was wondering why the idea to write a full, tutorial programming manual was dropped. The whole of the early '80s micro boom and bedroom coders was based upon not on the "cheap" hardware such as the BBC Micro and the Sinclair ZX81/Spectrum but mainly the comprehensive and very educational manuals which came with them. So, why was the idea of the accompanying educational material dropped?

Eben: This is partly a resourcing issue (we’re only just able to develop the hardware and get it out of the door), and partly a realization that other people can do this much better than we can. Almost any generic Linux programming tutorial should apply to Raspberry Pi. In time perhaps we can bundle some of the best ones on the device to give people a leg up when they start; we’re already planning to do this with the excellent NeHe OpenGL ES tutorials.

We need to bear in mind how much easier it is to get access to educational material now than it was in the 1980s. I remember spending months trying to dig up information about Bresenham’s algorithm (ironically to write an Elite clone on the BBC Micro – I hope David isn’t reading this), when now you can just Google it. Access to online tutorials is one of the reasons we decided to do a Model B with a bundled Ethernet adapter.

Or convince a few suppliers to donate some at-cost?

Re:HDMI to VGA (0)

Anonymous Coward | more than 2 years ago | (#37401588)

The product you are pointing at is just a wire, not a converter. Can the Raspberry Pi output analogue VGA from its HDMI port? This isn't the conclusion I drew from the answers above, though I stand willing to be corrected.

Re:HDMI to VGA (5, Informative)

josath (460165) | more than 2 years ago | (#37401590)

That cable is totally non standard, for crazy devices that output analog over their HDMI port. Most do not. HDMI is digital, VGA is analog, you can't convert from one to the other with a simple cable. It would not work for the raspberry pi (notice how the page says NOT FROM COMPUTER OR LAPTOP on it)

Re:HDMI to VGA (0)

Anonymous Coward | more than 2 years ago | (#37401700)

Unless I'm mistaken, the BCM2835 does not ouput analog over HDMI, so that cable will not work. If you're going to need to convert it won't cost $6.99 anymore.

Re:HDMI to VGA (1)

Moryath (553296) | more than 2 years ago | (#37401762)

That makes a difference.

I was presuming they were using a more standard chip, similar to those that typically output DVI and would accept any old DVI-to-VGA converter with no trouble (DVI being the same, except for form factor, in pinouts when running in full digital mode).

Re:HDMI to VGA (2)

LordByronStyrofoam (587954) | more than 2 years ago | (#37401816)

From the Amazon page for this cable: "NOTE: this cable don't support signal from VCR, COMPUTER or LAPTOP output."

Re:HDMI to VGA (0)

sylvandb (308927) | more than 2 years ago | (#37401962)

Because that cable only works for devices which output analog thru the hdmi connector, and not a typical computer. And judging by the interview answer, it stands 0 chance of working with the Rasberry Pi.

NOTE: this cable don't support signal from VCR, COMPUTER or LAPTOP output.

LWATCDR (28044) | more than 2 years ago | (#37402158)

Many monitors now come with HDMI and just about every HDTV does. Maybe the will make a version with RGB in the future but for now HDMI is the correct choice IMHO.
Composite means that any of those old TVs and or monitors will work just fine so you do have a source of old cheap displays to work with not to mention projectors and cheap LCD displays that are used in cars.
Over all I think this will rock. IMHO it is in fact a modern Commodore 64 but even better.

parallel computing: expose the VC core (4, Interesting)

Jerry Atrick (2461566) | more than 2 years ago | (#37402772)

The VideoCore vector core is an astounding source of MIPS, albeit 16bit ones. It's a real pity Broadcom hide it behind high level libraries and don't give the manuals out easily. If pi manages to expose a 16way4K register SIMD device to eager programmers magical things could happen. And there must be distributed apps able to use massive integer performance out there.

It's a hell of a lot of fun writing for it and really instructive in managed caching and data flow to keep the unit fed. Training a new generation of programmers those skills has to be a winner.

Re:Ebon who? (1)

rec9140 (732463) | more than 2 years ago | (#37408538)

"Why the skepticism?"

Well for one... lets start with the ever changing form factor and abilities.

Started out as about the size of 2 USB sticks. With HDMI on one end, and then USB on the other. Now its to credit card size, 256MB. (Yes, I read their fora about the 512MB PoP memory issue. thanks)

Next, plans to use Ubuntu, which this is perfect and right up Canonicals alley, so you would think! WRONG! WRONG! Canoncial (see https://bugs.launchpad.net/ubuntu/+bug/848154 [launchpad.net] ) PULLED the plug on the ARM V6 support and only supports the OMAP, basically TI is paying them to support the Beagleboards, so anything else ARM based is hosed, and you will have to go to Debian, or others. Thats fine, BUT... your targeting this to be used to do things like oh, play MP3's.. well then you have just run a foul of the DFSG, and 99.9999% of the Debian stuff has NO MP3 support unless you RECOMPILE IT! So your not going to do apt-get install mediaplayersoftware as it has NO MP3 support. Its great that it supports Ogg, but I provide Ogg formatted streams, and NO ONE USES them, but me. No arch or fedora doesn't count, first RPM based, and thanks but I've had enough dealings with RPM's on CentOS to say NO THANK YOU! Versus on Debian based DEBS and apt, simple as apt-get install, done.

Lets move on to connecing to see something..

HDMI? fail. Sure for the tech user side this not an issue. But if you aiming as stated by RPI that they want to see this in schools and developing areas, then HDMI is not a choice. Tons of old VGA monitors.

Oh..but we have compsite... Ok.. is that NTSC, PAL, or SECAM? And if its selectable how will I select it to start? If you need to keep costs under control your not going build 10K NTSC, 10K PAL, 1 SECAM, thats an inventory nightmare and cost issue right there.

Next, peripherals? Yes, the techies will walk over to their parts bin and pull out a USB hub, keyboard, mouse, no problem. Don't have it pick up some via ebay or if your lucky a decent local source. Again the techies aside, no problem. Back to that other target area, schools and developing areas. They are not likely to have spares of this available, and/or resources, namely $$$$, to fund purchase. And those touting get them from ebay etc... Ok... how is that going to work in the middle of the Africa for an area which may or may not have any data access, no ebay account, and no paypal account, let alone where its going to be shipped. Oh... groups/companies will donate those for projects. Great. You've got 100% commitments for 100% fulfment on these projects? Otherwise sourcing the various components for power supply, keyboard, mouse, hub etc. are not cheap, and easily will outpace the cost of the $25/35 board itself. And counter to what their spokeswoman on their fora thinks, this is not a "straw man" arguement. This IS an issue, and you need to have a plan on how your going to provide the WHOLE SYSTEM to users, and its not going to be $25 or $35, more like $75-99 with power supply, SD card with OS, keyboard, mouse, hub, HDMI cable, and/or VGA converter..... I love all those touting these $3 HDMI cables on ebay, and $7 s/h, again thats fine for the techie crowd who needs to pick up a few items, its not so good for some school in the middle of the Africa!

Now. I think this a FANTASTIC IDEA.. And I am game for 10 of the $35 Model B's right now, ship them over. If I can get their version of Debian to work with my project then I've solved a huge problem. I am very interested in this project... but I have doubts about the ability of this project to be viable OUTSIDE THE TECH ARENA, ie: those using the Ardurinos and Beagleboards. I am clearly in the techie developer side of this. I've got a price point I need to meet and trying to use a $150+ beagleboard don't cut it..

Personally, its a great idea, but dump the schools and delvoping areas aspect of this, and focus on competing in the Ardurino/Beagleboard arena, where there are people willing to pay for this device. I easily would pay $50 for the model b, and $99 for a 512MB version with other features. Oh, and you need to get others to beat down on Canocial to get their ARM V6 support back (Thats what the BBC article used, Karmic last V6 compatible), IF you want to continue to float the schools and developing areas portion. Why? Like it or not (and I have huge issues with canoncial on things) they've done more to make Linux a viable option to many users and make stupidly easy to get software installed and going with a few clicks or a simple command line. You might push the compile method/mode for the tech school users, but the other side of this, DO NOT CARE ONE bit! They want to install software and get on with it. And Canoncial has done that, and the support for it is far more widespread than the base Debian. Sure some of the Ubuntu stuff will install back to Debian, but you've lost the PPA's etc. that make some of this so easy to install along with the driver support, codex support etc..

I think the various areas they want to support are pulling them in opposite directions and are causing them problems. They need to pick a side tech (Ardurino) or schools/developing areas. There is no middle ground on this.

Your question was answered adequately in the comments. RS232C is not cheap. This really sucks, because it *is* simple from our perspective as users. But, c'est la vie.

I'm a bit sorry that they are thinking of WiFi and Ethernet as an either-or proposition, and I agree that at least in principle it would be nice to have an SATA jack, but wow, that's a pretty substantial change from the current form factor. SATA is really problematic, too: do you do ESATA? Powered or non? Or plain SATA, and assume the drive will be in a box with the device?

If you go to the Raspberry Pi forums you will see the answer in several topics. The answers is a solid yes, eventually. Right now they're just trying to get a final unit and peripherals (power supplies, possible cases) set and shipped. The next planned step are expansion cards/shields (think Arduino). The cards are largely to make up for certain short comings (WiFi, VGA and experimentation boards). The next planned step are variants (POE, possible native ports for RS-232 or VGA, memory upgrades) possibly including.

The timeline as I understand it is: November is the planned shipping date for the first round. The second round sometime next year will be minor fixes and shields. The third round will be the variants round but that maybe mid to late next year. A lot of this is based on volunteer time and parts availability. That why he said it would be great if a Chinese company could clone the project.

No need to get rude over someone's reply, even if it turns out to be an answer to the wrong question...

Great interview! (0)

This is the most interesting interview I've read on Slashdot in a long time. Eben and his team sound like they have great priorities with Raspberry Pi and have project planning that's firmly grounded in reality. I'm very much looking forward to supporting this project in the future.

We’ve said elsewhere that 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, so we don’t have the same set of incentives as a regular company.

The Pi itself is already supercheap, but if Chinese cloners start cranking out clones we might be able to buy even cheaper versions on DealExtreme. They'll also probably have features added, as the cloners usually do.

I suspect that learning gpgpu programming and cross-computer applications will be vital for the future. If they are nobbled on the Pi, it may be missing a major trick.
I don't understand the rationale behind the Model A. I paid heavily for my BBC Model B which included things I never used but at least I had the memory to run any software - unlike the BBC Model A. Cutting out network functionality for a price point is like cutting off your feet to fit your bicycle. Design the thing with all necessary bells and whistles and clearly defined interface standards for cloners. Early adopters will pay for it. Cloners will bring the price down.
