I&#x27;m assuming they are and that makes it even more amazing I think.

My 2 cents on this device: you are replicating the 1980s &quot;computer in the keyboard&quot;. Back then, the issue was the lack of screens, so TV were used instead.For educational purposes, the same problem exist today: however, kids will not have a space HDMI screen with a micro HDMI cable.The replacement screen that most people have is different: it&#x27;s a smartphone, as there are more smartphones than TVs.So a &quot;notch&quot; or receptacle on top on the keyboard, to secure a smartphone into place, would be helpful: the use case would be powering the 400 from the smartphone AC adapter (kids may not have a spare adapter matching the pi4 power requirements), plugging the phone into the 400 using a USB cable to keep the phone charged, use the phone as the screen - without it falling out and breaking, or hanging by a cable.Android being finicky, you may not be able to have autodetection&#x2F;USB gadget mode, but a remote desktop solution would go a long way.It is not possible at the moment, given the 400 power requirements, but newer&#x2F;more powerful AC adapters will eventually be more common.This leaves the notch, which you may want to consider in the next revision

Whats the relation between Broadcom and RPi? Isn’t Eben employed by Broadcom?

The pleasant surprise is you all make improvements to the hardware and the software that really enhance the experience.Nowadays, leading billion dollar tech companies often come out with upgrades that highlight being a few microns thinner and camera resolution without really launching actual innovative products or without enhancing the user experience.Thank you.

You&#x27;re right. The Raspberry Pi Foundation is an educational charity. We&#x27;re funded, in the main, by the sales of Raspberry Pi hardware.That the hardware and software engineers at Raspberry Pi Trading can keep innovating and producing such amazing products, astounds me.

Truly amazing how the Raspberry Pi team keeps innovating.As far as I know, they&#x27;re not a billion dollar company yet they keep innovating by making better Pi&#x27;s and continuously upgrading the builder&#x2F;user experience.Congratulations to Upton and team!

&gt; [...] with a ~22 times lower price...and roughly 1800 times the clock speed.
One millions times the colors that the C64 display[1].
It even comes with User Port (in spirit)[2].[1]
Yes, the number of colors a home computer could display was a major selling point back then. My C64 only hat 16, my friends CPC had 32, including the rad &quot;Bright White&quot; which enabled stunning effects. Man, I envied that.[2] Exposed GPIO header is super awesome and quite similar to the C64 User Port. Even more awesome was the Commodore&#x27;s Expansion Port which basically exposed its bus. It think something like this would not be practically possible with today&#x27;s GHz clock speeds but still this was super awesome and allowed (and required) you to even dig deeper into the internal workings of your machine.

Yup, FFW 38 years into the future and the Commodore 64 is reborn, only with a ~22 times lower price.

This is such a great idea. Plug it into a tv and you have a PC. Plug in an SSD with movies and you have a media center, no extra assembly required!

Not sure about that, but there are lots of portable monitors that have HDMI input that should work fine; eg: <a href="https:&#x2F;&#x2F;www.amazon.com&#x2F;Portable-Monitor-Display-Speakers-Include&#x2F;dp&#x2F;B08JCGJNQ8" rel="nofollow">https:&#x2F;&#x2F;www.amazon.com&#x2F;Portable-Monitor-Display-Speakers-Inc...</a> (Not a recomendation and I haven&#x27;t tried this one).

Eek, $236,- for a monitor for a $100 system? Hard pass. For $236 you can get a fairly decent tablet nowadays.That said, what are some affordable &#x2F; basic screens for a RPI?

This is really cool. Does it support an Asus Zenscreen USB C portable monitor? I recently started traveling with one as a second screen. Weighs less than a kilo.<a href="https:&#x2F;&#x2F;www.amazon.com&#x2F;ASUS-ZenScreen-MB16AC-Portable-Monitor&#x2F;dp&#x2F;B071S84ZW7" rel="nofollow">https:&#x2F;&#x2F;www.amazon.com&#x2F;ASUS-ZenScreen-MB16AC-Portable-Monito...</a>Setting it up on my MacBook Pro required the &#x27;DisplayLink Manager&#x27; util to be installed, but otherwise it just works and doesn&#x27;t need a second power source.I wonder if that would still work with this Raspberry Pi 400.

That was my very first thought too. Joyful moments indeed.

It reminds me the joyful moments while I plugged my Commodore 64 to TV set.

This is an awesome idea, brings me back to my Sinclair days - grab the computer, plug it into the TV, done. Perfect for kids.Only one concern: I own one of the keyboards (they also have a US layout) and they’re not bad, but the right cursor key fails to register sometimes. So let’s hope they tweaked the build quality a bit in that regard.

Fantastic. They clearly took into account vast user base not interested in electronics and tinkering and just interested in a cheap PC. SD card with system included which was a hassle for novice users. And they even kept GPIO outside for those like me.I&#x27;m so glad about Raspberry Pi popularity. There are many superior hardware platforms but having one that&#x27;s really popular massively speeds up prototyping when most modules and sensors have libraries written for it, and you know you are testing them on the same hardware on which they were developed.

The clock speed is up from 1.5GHz to 1.8GHz, and there is a heat spreader built in. <a href="https:&#x2F;&#x2F;www.cnx-software.com&#x2F;2020&#x2F;11&#x2F;02&#x2F;raspberry-pi-400-teardown&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.cnx-software.com&#x2F;2020&#x2F;11&#x2F;02&#x2F;raspberry-pi-400-tea...</a>

Just watched the teardown video from there. Man, that&#x27;s a lovely design.

It&#x27;s a new design of boad (not a Pi4 in a case) and has a large heat spreader inside, and the C0 2711 chip which has better clock gating so blocks can be turned off the save power. This means we can run at 1800 by default. It runs very cool.<a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;forums&#x2F;viewtopic.php?p=1752436#p1752436" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;forums&#x2F;viewtopic.php?p=1752436#p...</a>

The BCM2711 SoC inside is a newer stepping (C0 vs B0 in Pi 4 model B), and can run faster and slightly cooler than the older revision.Thus the Pi 400 has a 1.8 GHz default clock, while the Pi 4 model B has a 1.5 GHz clock.Note that I just checked my Compute Module 4, and it also has the C0 revision of the chip... so it&#x27;s interesting the Pi Foundation chose to keep it at the default 1.5 GHz.It might have to do with the fact that the Pi 400 has a massive keyboard-sized heatsink attached to the SoC in the unit!

Yeah, so I watched a teardown from one of the sibling comments. Looks like there are vents underneath, but no fan (which would have ruined it for me). Turns out it&#x27;s got both a huge heat spreader and a newer version of the Broadcom SOC. That&#x27;s really interesting, because it means they&#x27;ve got the bugs ironed out to be able to do a better pi 4 board which isn&#x27;t so finicky about its enclosures. And that means I could potentially upgrade the pi 3 that&#x27;s currently sat in my dusty workshop without caring about fans getting clogged. (yes, I know there are passively-cooled pi 4 cases about. They don&#x27;t quite do it for me.)

It’s a custom pcb in keyboard format with vents at the back and huge metal heat sink&#x2F;anti flex plate.

It&#x27;s easy to overclock pi 4 (revison 1.2) to 1.8 GHz as well, so they are probably very similar.

I&#x27;m intrigued by the &quot;faster, cooler&quot; comment. Anyone know what that refers to? It looks like there aren&#x27;t any vents on the visible surfaces, so I&#x27;m guessing there&#x27;s been a hardware rev to make thermal throttling less of a problem?If so, that might imply a pi 4 board release some time soon, which would be nice.

I started with this: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Vector-06C" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Vector-06C</a>

Love it. I first learned BASIC on a keyboard form-factor Atari 800 XL [0], plugged into an old B&amp;W 12&quot; television. I think this device will be much more approachable, and open the Pi&#x2F;Linux ecosystem to many more users.[0] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Atari_8-bit_family#Newer_XL_machines" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Atari_8-bit_family#Newer_XL_ma...</a>

I would imagine that a USB-C controller, would add a fair bit to the price, maybe a later SOC will support it.

[Unpopular opinion] having been spoiled by a working case† of USB-C, I wish there were 6 of those at the back instead of all the different plugs (save for Ethernet and GPIO)...[Even more unpopular opinion] ... even if they were functionally different and marked explicitly as USB 3 x3, HDMI x2, power x1.† I hear this is not everyone&#x27;s case, but I just decided to buy a bunch of USB-C &lt;-&gt; whatever cables and stash the old cables in a drawer. The experience has been refreshing ever since, even emergency charging the laptop over 5W.

Yeah, they should&#x27;ve gone with full-sized HDMI ports, since they have the room.

My memories prefer an Apple II theme. Either brown and beige or beige on off-white.

Yup, and if you look at Jeff Geerling&#x27;s teardown photos, there were acres of extra PCB space and they easily could&#x27;ve switched back to regular HDMI for this unit.It&#x27;s a senseless design defect in what otherwise looks to be a splendid little unit.If I end up with one of these, the first thing I&#x27;m gonna do is cut a little base-plate to glue it to, which extends behind the unit and has places to secure the HDMI cables (and maybe some other goodies as long as I&#x27;m at it), to prevent exactly the torque we all know happens.

I can&#x27;t understand the reason why this port even was invented. The cables I have seen are few times bigger than the connector itself, so there is a lot of pressure and tension being applied on that tiny port. Only thing I can think of is saving some PCB space, but if they put more effort into arranging components, then I am sure full size port would fit nicely.

I think the Raspberry Pi 4 should have had one standard HDMI port and one micro HDMI port. That would have addressed the majority of users. Only the minority of users that want a second monitor on their RPi would need an adapter or special cable.

This tugs all the heartstrings for me as it mimics the computers of the early 80s. My only criticism is that their use of micro-HDMI makes it very easy for children to wreck the machine. I&#x27;ve had this happen twice to me on RPi4s, and it&#x27;s not a terribly pleasant experience.Now all I want from them is a custom edition with the function keys in red, the rest in black, and the body in beige.

it&#x27;s called glamour - you intentionally don&#x27;t show everything and let the imagination fill in the gaps. It&#x27;s a gorgeous advertising technique when done properly and a terribly annoying one when done poorly. I&#x27;d argue here it might have come close but obviously not for you.Glamour is mightily hard. I don&#x27;t even try it when doing products. Apple&#x27;s pulled it off a few times.

If I were doing it I&#x27;d use a cleaner background, some background music, add a British voiceover, and do more continuous shots. The cut away from the wire going into the port hurt me :(

What a clean and stylish execution. I have too many pis already but I think they just sold me another.That video ad is Steve Jobs-level excellence.

It&#x27;s write speed; sorry about that, I should probably be more specific! All the benchmarks I&#x27;m using are from this Wiki page (<a href="http:&#x2F;&#x2F;www.pidramble.com&#x2F;wiki&#x2F;benchmarks&#x2F;microsd-cards" rel="nofollow">http:&#x2F;&#x2F;www.pidramble.com&#x2F;wiki&#x2F;benchmarks&#x2F;microsd-cards</a>) — though I need to update that page to include some more USB&#x2F;SATA&#x2F;NVMe performance benchmarks since I&#x27;m now using a lot more drives with the Pi 4 and CM4 (and skipping microSD entirely for most builds).

One comment regarding your &quot;performance comparison&quot; graph. Is the &quot;dd&quot; result read or write? I wondered the same thing with your Compute Module 4 post.

There&#x27;s an aluminium plate that serves as a heat sink and appears to work quite well, apparently.

According to the article, it isn&#x27;t a problem; the heat sink is big enough to not need a fan. Nice bonus that it&#x27;s a slightly faster SoC.I have a Pi 4B with a heat sink and fan that&#x27;s running BOINC 24x7 (yielding a RAC of about 750-775 on World Community Grid), and with the fan connected to 3.3V it runs at a comfortable 52-54°C with absolutely no throttling. I think I&#x27;m going to try overclocking it a bit and see how it handles it.

They pushed out a firmware update last year that apparently solves some of the heat issues.<a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;blog&#x2F;thermal-testing-raspberry-pi-4&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;blog&#x2F;thermal-testing-raspberry-p...</a>

It runs cooler than the Pi 4 model B, at a higher clock speed. The newer chip helps with that, in addition to the massive heat sink on top of it!

On the subject of heat, how is it on this thing? I&#x27;ve heard stories about the Pi 4 B.

&gt;simple RPi branded monitor with a Pi built inOh, I&#x27;d definitely be up for that!!

agree the keyboard-in-one is great -also fyi the pi-top project has a DIY &#x27;all in one&#x27; for the PI:<a href="https:&#x2F;&#x2F;www.pi-top.com&#x2F;products&#x2F;pi-top-ceed" rel="nofollow">https:&#x2F;&#x2F;www.pi-top.com&#x2F;products&#x2F;pi-top-ceed</a>and a DIY laptop:<a href="https:&#x2F;&#x2F;www.pi-top.com&#x2F;products&#x2F;pi-top-3" rel="nofollow">https:&#x2F;&#x2F;www.pi-top.com&#x2F;products&#x2F;pi-top-3</a>only claim pi-3 compatibility at the moment, not sure if it would still work with 4, probably need some adapters or so(maybe other projects like this, not sure)

Just watched a few videos on your channel and love it. Really great stuff.I love this Pi 400 and think in the new year I will pick one up for my son. We have a Pi 4 that we use a lot and he loves but like you say in your video it is a bit annoying with this little box off the side with a bunch of cables coming out of it.Not terrible by any means just annoying so I really love the form factor of it all being in the keyboard.I have thought for a while now they should do this kind of form factor or sell a simple RPi branded monitor with a Pi built in so I am happy to see they thought about it too. A keyboard is much more practical than a monitor of course so it is a far more sensible choice!Really hope this sells well and they continue with this kind of form factor in the future. Even a slightly bigger keyboard with a &quot;forehead&quot; (C64 vibes) would be excellent.

Excellent, I was looking for this sort of info.(side note, I love the ansible roles you&#x27;ve made, especially AWX, saved me a bunch of time back in 2018)

At least superficially it looks like it might be the same basic keyboard as the official Raspberry Pi keyboard that they already had. If so the experience is... not great but not horrible. It&#x27;s not the worst chiclet keyboard I&#x27;ve used, I&#x27;d rate it as adequate. You would not want to use it as your primary keyboard all day, but that&#x27;s also not what it&#x27;s intended for.

(This is assuming the existing keyboards are the same) Pretty decent scissor-switch, but one of mine squeaks when typing some.

The Pi Keyboard was decent. I would expect this to be the same just with the Pi integrated.

Apple made the chiclet keyboard cool again. It might be OK.Gen-x who remember the TRS80 MC10 and its keyboard remember chiclet keyboards as not much better than membrane keyboards (Consider the ZX81 Spectrum)But decades later Apple started shipping chiclet-appearing keyboards that actually worked, so the style has been somewhat revitalized.That said, yeah they could be shipping a 1980s quality chiclet keyboard or a 2020s quality chiclet keyboard, so that&#x27;s worrisome.

Or alternatively, how hard is it to plug in and use another keyboard instead?

It feels plasticky, but not flimsy. I think it uses scissor switches, so it feels better than a standard rubberdome, but it&#x27;s obviously not going to replace your Model M or Cherry-switch keyboard.Sauce: I have the keyboard without the computer in it, from when I bought a Pi 4 &quot;starter kit&quot; a year ago.

How is the keyboard? It looks, uh, cheap, so I&#x27;m curious if typing on it is an ok experience.

With a little bit of code, you should be able to pipe keyboard input to one of the USB ports.

One of my main uses for random keyboards is hooking them onto a raspberry pi that needs some local debugging...

Yes, I think Gordon Hollingsworth from Raspberry Pi has posted somewhere specifically how to do it (maybe in the comments on the post on the Pi website?).

You should probably be able to use Synergy (<a href="https:&#x2F;&#x2F;symless.com&#x2F;synergy" rel="nofollow">https:&#x2F;&#x2F;symless.com&#x2F;synergy</a>)

Can you use the keyboard.... as a keyboard for other computers?

Curious if you have any specs on the ribbon cable that connects the keyboard. It looks like it must carry more than USB?

Hey Jeff, I recently bought the RPi Keyboard Hub (Pictured in OP and In parent blog) for its soft keys (Got bone issues), I was pleasantly surprised with the quality. I use Wacom Touch Tablet for trackpad along with a Steel series mouse in its Hub; But I&#x27;m worried about saturating the bandwidth as it&#x27;s just USB 2.0 although I haven&#x27;t found any conclusive issues.Have you tested the Keyboard hub&#x27;s limits? Controller seems to be QinHeng Electronics USB-Serial.

That seems to more or less already exist: <a href="https:&#x2F;&#x2F;shop.pimoroni.com&#x2F;products&#x2F;raspberry-pi-keyboard" rel="nofollow">https:&#x2F;&#x2F;shop.pimoroni.com&#x2F;products&#x2F;raspberry-pi-keyboard</a>

I agree, I wish this was the case but it&#x27;s still a compelling gift for my nieces and nephews and tickles my nostalgia for the era of computing that it mimics.

This is slightly disappointing, I was expecting it to be some kind of case for the the Compute Module (or at least for the RPi4. I don&#x27;t know if it&#x27;s unrealistic, but it would be nice to have some sort of upgrade or repair possibilities.

Have you tried the coffee spilling test on it yet?

Just wanted to say that I&#x27;ve been watching your Pi videos on YouTube over the last few months and I really enjoy them. Your video about trying to get a GPU working with a Raspberry Pi was particularly fascinating. Keep up the great work.

... and a mechanical keyboard, to complete the possibly unintentional Atari reference.(Folklore says the original product plan had the Atari 400 come with 4K of RAM, and the 800 8K... and then memory got cheaper by release.)

&gt; Fun fact: the Pi 400 (and Compute Module 4) both have newer revisions of the BCM2711 SoC (C0 instead of B0), and that&#x27;s part of the reason the clock speed is higher on the Pi 400 (1.8 GHz) than on the regular Pi 4 model B (1.5 GHz)—the newer revision apparently handles faster clocks and scaling with less heat than the older revision.Reading your article&gt; the Pi 400 didn&#x27;t overheat even when I was running it with an overclock to 2.147 GHz, the maximum it allows currentlyThis only makes me wish they sold an 800 version with 8 GB of RAM, just like the Pi 4.

Thank you geerlingguy for your ansible repositories!!

I was lucky to get a pre-release version to test, and I decided to tear it down before I started trying it out. I posted this blog post with detailed pictures of the insides, and some more details and performance benchmarks: <a href="https:&#x2F;&#x2F;www.jeffgeerling.com&#x2F;blog&#x2F;2020&#x2F;raspberry-pi-400-teardown-and-review" rel="nofollow">https:&#x2F;&#x2F;www.jeffgeerling.com&#x2F;blog&#x2F;2020&#x2F;raspberry-pi-400-tear...</a>There are also a couple videos linked in the post, if you&#x27;re more visually-inclined.Fun fact: the Pi 400 (and Compute Module 4) both have newer revisions of the BCM2711 SoC (C0 instead of B0), and that&#x27;s part of the reason the clock speed is higher on the Pi 400 (1.8 GHz) than on the regular Pi 4 model B (1.5 GHz)—the newer revision apparently handles faster clocks and scaling with less heat than the older revision.

Why was it not just called a &quot;home computer&quot; ?

Like everywhere else, schools here in India also have gone online. But students here do not have computers. They are taking their classes using parents smartphones. Now you can imagine all the issues that one can face while using this setup. Moreover it&#x27;s not feasible to sit with a mobile phone for 5-6 hrs of classes.My father is a teacher and I had this idea to let his students use Raspberry PI with TVs but this is perfect for them.

I love it, I really do.The logitech keyboards w&#x2F; the touchpad built in suck.This just looks adorable.

How usable is it? What desktop runs out of the box and does it lag? Genuinely missing Linux and thinking this would be fun, but only if I can use an up to date distro and it doesn’t hang all the time.

Got myself a pre-release version to test with Ubuntu. The higher clock speed at 1.8GHz makes such a nice difference, <a href="https:&#x2F;&#x2F;ubuntu.com&#x2F;blog&#x2F;raspberry-pi-400-with-ubuntu-support" rel="nofollow">https:&#x2F;&#x2F;ubuntu.com&#x2F;blog&#x2F;raspberry-pi-400-with-ubuntu-support</a>

I have indeed got enough spare displays but I just want to carry my Pi 4 around and use it in public transport and everywhere so a separate display and a web of cables doesn&#x27;t seem particularly convenient. Perhaps I could buy a PiTop but their current model is not a laptop.

Why quadruple, anyway? I&#x27;ve seen quite a number of ~$200 laptops and found their screens and batteries tolerable (although, obviously, not really good).

That would probably quadruple the price. Look at PiTop. They used to include batteries and a display, but have moved away from that, as these are the most expensive peripherals.
You can by a cheap display, or use your existing TV. A USB power supply isn&#x27;t too expensive either.

The display seems to me to be a bigger problem than the battery. Small, 3 Amp capable USB batteries are common and cheap ($10-$20 on Amazon). Displays are expensive (and need their own power source), but people can at least use TVs like they did with those 1980s PCs.I sort of suspect that if this is really successful, they might come out with a laptop version. That&#x27;d be nice.

I would buy immediately if it also had a display and a battery to make a laptop (and a cooler so I wouldn&#x27;t have to worry when I start a long compilation routine on it). Looks great otherwise.

One of the YouTube reviews deals specifically with retro gaming on the Pi 400: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=nopc7mJUDkM&amp;list=PLcd1Q0-YkB1euCFXbFXgAQYy9ZCig6-eA&amp;index=3" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=nopc7mJUDkM&amp;list=PLcd1Q0-YkB...</a> — also that channel spent a little time rendering some concepts for more retro-looking Pi 400 designs.

&quot;Very old&quot; means different things to different people. If you want to run the sorts of games that used to run on &quot;keyboard plugged into the TV&quot; computers, think Z80, not VR4300.

I&#x27;ve got a RPI with RetroPi, it... sorta works, but the cheap controllers aren&#x27;t very good, and there&#x27;s a noticeable input lag in games like Mario Bros. N64 games don&#x27;t get a decent framerate. Mind you this is with an RPI 2 or 3 so not the best hardware either.I got a refurbished N64 as well, works as intended.

After combining two broken Amiga 500s into one single working one, I had an Amiga case and an Amiga keyboard left over. The nice thing about the Amiga keyboard is that it is pretty much a serial device, so it wasn&#x27;t hard to set up an Arduino Pro Micro to act as a keyboard-to-usb adapter.Then I put in a Raspberry Pi with a Retropie SD card, two gamepads, a mouse, and that&#x27;s all.I didn&#x27;t put a lot of effort into making it look nice, so it&#x27;s basically just a bunch of cables coming out the back of the Amiga, but at first glance it&#x27;s still an ordinary Amiga.Works pretty well overall for Amiga, C64, Spectrum, Atari, and DOS games. Of course boot time is not great, and add to that the time spent navigating Retropie&#x27;s menu system, it&#x27;s all a bit of a hassle. It does work better than my actual Amiga for &quot;productivity&quot; applications because I can set it up with more memory and better networking options.

I’m putting one together soon. The retrotink ultimate stopped being made last year, which is very sad. The community hasn’t picked up the source yet. It’s a matter of time though. I’m going with a PI2SCART for video output. I would use this Raspi 400, but the GPIO location is not well suited for hats.I’m going this route because I also want the flexibility to have a computer on my CRTs. If you want pure gaming, then look into MiSTer FPGA.

I anyone using the Pi to run very old computer games? Because this could be the perfect gaming console for the nostalgic.

Haha, this is exactly what I&#x27;d like to see but for the MiSTer FPGA system.I like retro computing and while the RPi can do that, doing it in hardware is even better.However, now that it&#x27;s released, maybe it can be disassembled and reconnected for that one, if it fits...

SD cards really let the Pi down. Thank god for USB boot.

Yeh the keyboard for other computers would be awesome.

I believe the USB-C power port can be used for USB-2 gadget mode, so you could in theory configure the Pi 400 to act as a keyboard for another computer :-)

If one of the usb port allow OTG someone can hack a driver to turn the 400 into a keyboard (albeit a very bloated one as it would be running a full OS!).

First impression: yes, this looks beautiful, reminiscent of the microcomputer revolution, and of course I wish I could get one.What would I change?It&#x27;s a pity that the keyboard is connected using a flip-up ribbon, rather than internal USB. Although I can see why the target market (education) just prefers an all-in-one computer, this also means that the RPi 400 can&#x27;t be used as a keyboard for other computers. Therefore I&#x27;ll still need to carry a keyboard around.There will be software options for virtual USB host (e.g. shameless plugs for the EspUSB which uses WiFi, or KeyMouSerial which uses serial) but in practice, those wouldn&#x27;t be as easy for most hackers. There&#x27;s also no F12 key, which is needed for system configuration on some distros.The two Micro-HDMI ports are quite small and close together (especially when using a 3-way micro-mini-full size HDMI adaptor).Like Apple, there&#x27;s no headphone jack. Also no built-in SD reader, so I&#x27;d still need to carry a USB card reader (unlike my laptop, which can go directly from camera SD cards to HDMI on a projector).Final nitpick: if this keyboard is intended for young people, their hands are smaller, so full-size keys are actually less comfortable. (believe it or not, I&#x27;ve even seen keyboards intended for children that have extra-large keys). A design with smaller keys that could fit in my large pocket (e.g. TI-84 sized device) would be preferable.What the RPi Foundation has done is an excellent feat of engineering, and they should and will be rewarded by the market for their innovation. It&#x27;s a great product. I just still see some room for future improvements.

That GPIO port looks so much like the old C64 cartridge port: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Commodore_64#&#x2F;media&#x2F;File:Commodore-64-Computer-BL.jpg" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Commodore_64#&#x2F;media&#x2F;File:Commo...</a>Wouldn&#x27;t it be fun to ship cartridge games again?

Demanding facts and methodology eh? You don’t seem to understand benchmarks.

That would mean performence more then doubled on a yearly basis.How do you figure? They were released 30+ years apart. 2^30 would be a billion times faster. Instead it&#x27;s something under 19 doublings, nowhere close to doubling every year for 37 years.

Cool. That would mean performence more then doubled on a yearly basis.Unfortunately, your &quot;reference&quot; is just the same numbers you posted but as an image. I don&#x27;t know if this counts as a &quot;reference&quot; :)Any links to who performed those benchmarks?

I hadn&#x27;t seen that the new CMs don&#x27;t use the SODIMM form factor anymore, that&#x27;s a bit disappointing.

If you want to upgrade you might as well just buy a regular RPi4 and plug in your own keyboard.

RPi do name the connector in the CM4 datasheet: <a href="https:&#x2F;&#x2F;datasheets.raspberrypi.org&#x2F;cm4&#x2F;cm4-datasheet.pdf" rel="nofollow">https:&#x2F;&#x2F;datasheets.raspberrypi.org&#x2F;cm4&#x2F;cm4-datasheet.pdf</a>You can buy the connector here: <a href="https:&#x2F;&#x2F;uk.rs-online.com&#x2F;web&#x2F;p&#x2F;products&#x2F;1362374&#x2F;?grossPrice=Y&amp;cm_mmc=UK-PPC-DS3A-_-google-_-3_UK_EN_PCB+Sockets_Hirose_Exact-_-Hirose+-+PCB+Sockets+-+1362374+--_-df40hc+3.0+100ds+0.4v+58&amp;matchtype=e&amp;kwd-360440442175&amp;s_kwcid=AL!7457!3!443699393884!e!!g!!df40hc%203.0%20100ds%200.4v%2058&amp;gclid=CjwKCAiA-f78BRBbEiwATKRRBC8Esi76AkQ1bSJYGLpJxmm5f_Dx4wXqlh1E3D5V0HGgEUkYMGRvpBoCiHEQAvD_BwE&amp;gclsrc=aw.ds" rel="nofollow">https:&#x2F;&#x2F;uk.rs-online.com&#x2F;web&#x2F;p&#x2F;products&#x2F;1362374&#x2F;?grossPrice=...</a>I agree with you though. RPi appeals to people with a wide range of skills. There are lots of programmers who want to use Pi to get more electronics knowledge, and RPi foundation could make that a bit easier for those people.(EDIT: I don&#x27;t understand why parent has been downvoted. A lot of similar devices do use newer more specialised connectors and it can be hard to work out who makes and supplies the connectors.)

I&#x27;ve seen a lot of devices like the CM that use a random connector and for some reason they never actually name the connector and its MPN. Alchitry and Parallela have &quot;weird&quot; connectors as well and it was always a pain in the ass to figure out which connector they&#x27;ve been using.

Why isn&#x27;t it just a CM plugged into the bottom of the keyboard circuit board for upgradability... it doesn&#x27;t bode well that Rasberry Pi&#x27;s own products aren&#x27;t using the weird connecter the CM has.

It&#x27;s not a straight conversion, parent poster refers to GB&#x2F;EU pricing of the product. A straight conversion would be 
~54£.I did a double take as well, and had to look it up.

Depends whether the reseller is selling the kit or just the device. Welectron for instance lists both, and device-only is 69 EUR. <a href="https:&#x2F;&#x2F;www.welectron.com&#x2F;Raspberry-Pi-400-Computer-DE" rel="nofollow">https:&#x2F;&#x2F;www.welectron.com&#x2F;Raspberry-Pi-400-Computer-DE</a>

&gt;€69 (DE)Where did you find that price? On the official purchase page[1] the lowest price is 97 EUR (which is around $113)[1] <a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;products&#x2F;raspberry-pi-400&#x2F;?resellerType=home&amp;variant=raspberry-pi-400-de-kit" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;products&#x2F;raspberry-pi-400&#x2F;?resel...</a>

For anyone wondering it is $70, meaning £67 or €69 (DE).

This is because the picture is for a British&#x2F;ISO layout, not out standard US&#x2F;ANSI layout.

I think it copies the macbook layout, like so many other mini keyboards:<a href="https:&#x2F;&#x2F;keyshorts.com&#x2F;blogs&#x2F;blog&#x2F;37615873-how-to-identify-macbook-keyboard-localization#us-international" rel="nofollow">https:&#x2F;&#x2F;keyshorts.com&#x2F;blogs&#x2F;blog&#x2F;37615873-how-to-identify-ma...</a>

The pipe and backslash are beside the Z key as well, making the left side shift key narrower.

I really want to like this, but the shrinking of the keys around the return key is a big turn off.

Oh, man, it&#x27;s like an 80s home computer for today. It&#x27;s just what every kid needs.

Schools don&#x27;t want to be debugging microSD and USB issues.

Also, the CM4 does work with native NVMe or SATA storage (at the expense of USB 3.0 ports).

The RPi4 SoC already has PCIe support; it&#x27;s used for the USB controller, but it wouldn&#x27;t be impossible to have a version that has an M.2 PCIe slot. It could be used for NVMe, WWAN or faster Ethernet.USB could remain available through USB OTG and it would sit in the middle between the RPi4 and the Compute Module 4. Using the USB power socket for OTG is doable already on the Pi4, but to do it in a fully supported way would need some extra components to properly handle USB-C configuration. Still cheaper than an H2plus

Or you know there&#x27;s this thing called eMMC that&#x27;s mostly pin compatible with SD cards and yet provide fast, resilient and cheap storage.

&gt; There are alternatives to RPiThe alternatives to RPi don&#x27;t have nearly as rich selection of polished software, vibrant community and ecosystem as Raspberry Pi has. The best parts (besides hacker-orientedness) of RPi are its uniformness and popularity.

If would make sense to be able to attach a $25 32GB SSD to the bottom of a RPI. Then add some kind of a U-shaped connector to connect the RPI to the SSD and a place for the screws, so that they are fixed back to back.

eMMC storage are comparatively very fast, and I believe they have a comparatively little or negligible impact on the end price (competitors like Hardkernel put it in the directly competing products).

This is misleading. You have removed the first part of that sentence &quot;Early on, the Raspberry Pi project leaned towards...&quot;Whilst education is still important, particularly on the charity side, these days the RPi Trading division explicitly targets multiple markets, for instance, the compute boards specifically targeted at industrial usage.
This product is described in their own press release as targeting the christmas toy market amongst others.

What percentage of raspberry pis do you think actually go to that &quot;target audience&quot;? 20%?

Sounds like you&#x27;re not the target audience for a RPi. They are meant to be cheap computers for &quot;the promotion of teaching basic computer science in schools and in developing countries&quot;[0]. Adding NVMe support would increase the price.There are alternatives to RPi that do what you want, odroid-h2plus for example.[0]: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Raspberry_Pi" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Raspberry_Pi</a>

Android phones are useles... no ethernet, no gpio, shitty cooling, hard to get an OS installed, hard to debug, and compared to RPI4, too expensive.RPi4 is great... small cheap, basically a full pc in a small box, with low power usage, low heat production, no noise, and yes... with a shitty storage solution.

There are countless Android phones with eMMC without much problems

FWIW I’ve used a rpi1 then 2 then 3 as my Kodi&#x2F;openelec&#x2F;libreelec box for years each and it’s been running very smoothly. Maybe not the most demanding in terms of storage writes but still, I’m very satisfied with it.

It&#x27;s still USB storage. It&#x27;s theoretically possible to solder a PCIe ssd on the Raspberry Pi 4. At the cost of USB 3 support.

vomit. There&#x27;s PCI lanes coming out of the CPU right? Even a bottom end Intel unit these days has one for an NVMe slot, not 5 devices down the bus.

2021 Compute Module 4 will have NVMe storage.

I know relatively little about the Compute Modules... Are there any decent &quot;racks&quot; for these that would allow you to assemble many of them into a single unit?

FWIW: Now you can get raw PCI-E access with the Compute Module [0] + IO Board [1], allowing you to put a SSD on there over a robust interface.But yeah, I would also love this to be built in on something like the RPI. Closest option according to my research is probably the Rock Pi, but then it&#x27;s not really straight forward to boot from it etc...[0]: <a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;products&#x2F;compute-module-4&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;products&#x2F;compute-module-4&#x2F;</a>

Have you tried using berryboot?Gives you an option to install os on external storage. 
You can set it up to dual boot multiple distros if you wanted.I agree pi4 would benefit from better storage options, but for the money it&#x27;s still a impressive package.

Pi 4 compute module breaks out the pcie port which is use for usb 3.0 on the pi 4. This means someone could make a motherboard with an m.2 M-key socket. The pcie port could also be routed to a switch to be split among multiple pcie devices such as usb 3.0, ethernet and so on.

I boot my RPi 4 entirely from USB with the Sep-3-2020 bootloader. No sd-card inserted. The Sandisk Extreme Pro benchmarks at 230 MB&#x2F;s on USB 3.0.

Sounds like they fixed (read: worked-around) that issue in <a href="https:&#x2F;&#x2F;github.com&#x2F;pftf&#x2F;RPi4&#x2F;releases&#x2F;tag&#x2F;v1.17" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;pftf&#x2F;RPi4&#x2F;releases&#x2F;tag&#x2F;v1.17</a>

I boot a RPi 4 via PXE (or rather, the RPi version of PXE, which is decidedly non-standard, meh). No SD card in the slot. No problem. Are you on the latest firmware?

The RPi 4 has USB 3 + UAS which is actually quite decent. I use it for Aarch64 development[1]. It boots and runs entirely off the SSD, and the performance is not spectacular but perfectly usable, and being it&#x27;s a regular SSD it should be at least as reliable as a laptop.It also has a firmware bug where it cannot boot unless there is an (empty, unused) SD card in the slot, which is annoying![1] <a href="https:&#x2F;&#x2F;rwmj.wordpress.com&#x2F;2020&#x2F;09&#x2F;24&#x2F;raspberry-pi-4-running-fedora-32&#x2F;" rel="nofollow">https:&#x2F;&#x2F;rwmj.wordpress.com&#x2F;2020&#x2F;09&#x2F;24&#x2F;raspberry-pi-4-running...</a>

normal SATA(2&#x2F;3) would be plenty good (even better if 2 ports).

&gt; An M2 SATA or NVMe would make this credible but 99% of the problems I&#x27;ve had with the Pi platform is storage related, either being knackered microSD cards, terrible performance or USB power problems.It sounds like literally all your problems would be addressed by using the official power supply and a USB-connected SSD - although your problems might very well be solved just by using the official power supply and a decent SD card.SATA and NVMe interfaces are something some nerds who aren&#x27;t the target audience for this hardware would like but they don&#x27;t address the real-world problems you mentioned at all.

Hah, just came across his blog while trying to debug an issue I&#x27;m having: <a href="https:&#x2F;&#x2F;www.jeffgeerling.com&#x2F;blog&#x2F;2018&#x2F;fixing-503-service-unavailable-and-endpoints-not-available-traefik-ingress-kubernetes" rel="nofollow">https:&#x2F;&#x2F;www.jeffgeerling.com&#x2F;blog&#x2F;2018&#x2F;fixing-503-service-un...</a>

Jeff Geerling (HN:geerlingguy, who is participating in this comments section) has demonstrated using a NVMe drive with the RPi 4 Compute Module and its IO board, which has a PCIe slot.<a href="https:&#x2F;&#x2F;youtu.be&#x2F;HUamq0ey8_M?t=429" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;HUamq0ey8_M?t=429</a>

I think usb-c&#x2F;usb 3 solved most of the problems.I used to have the low-power indicator show up all the time in the past, but it seems the usb-c power supply has resolved that.Additionally usb boot + usb3 speed has made running completely off of usb instead of sd a good solution. There are also pretty fast yet small form factor drives like the samsung fit to choose from as far as physical size.

Yes. I already know what I&#x27;m looking for. I posted a picture of it yesterday: <a href="https:&#x2F;&#x2F;imgur.com&#x2F;yjPMYaX" rel="nofollow">https:&#x2F;&#x2F;imgur.com&#x2F;yjPMYaX</a>(M600, sort of a NUC)

I agree 100% with this. I have a fairly large tinker shop with 20-30 different machines and initially bet on the Pi platform to do CNC&#x2F;Octoprint&#x2F;robotics&#x2F;etc controls, thinking I should standardize. Most of the Pis failed with storage issues eventually; be it eMMC, microSD or USB flash drives. Since then I&#x27;ve moved on to x86 based industrial motherboards which ended up costing about the same when you include everything. Zero problems since then. And boot times are now measured in seconds, not minutes.

Can we please have a Pi without a crappy storage interface. It&#x27;s either a microSD card or something dangling off USB. An M2 SATA or NVMe would make this credible but 99% of the problems I&#x27;ve had with the Pi platform is storage related, either being knackered microSD cards, terrible performance or USB power problems.

These look pretty decent for the price. I still wish there was proper storage but otherwise this looks really nice.I don&#x27;t have a use for one though. I only really use my pi4 as a Kodi box and my Pi2 is just a FTP server for my friends.

Is affordability the goal?I thought inspiration was.

Isn&#x27;t the goal to provide an affordable computer to those who currently can not afford one? Instead of selling a cool collectible…

I like the general idea but frankly this is underwhelming.Where’s the sense of fun?Given the origin of the raspberry pi being the old BBC and other home computers it would have been fun to have a solid computer with a full size keyboard reminiscent of the old 8 bit machines like the Acorn or the BBC micro.The is just a keyboard. And really a missed opportunity to be something unique and fun and exciting.This is kinda neat but nothing special. I’m not involuntarily reaching for my wallet.

&quot;In the teardown you can see there is only one board.&quot;I&#x27;m curious - can one buy that one board ?It is an odd form-factor that I have not seen a raspi use in the past (long and rectangular) - is it only sold as part of these keyboard units ?

I was hopping they would just use the compute module[1] and you could replace&#x2F;upgrade or even use it in another project. In the teardown you can see there is only one board. [2]I would have also though it would cost less but I guess integrating it directly is even cheaper.[1] <a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;blog&#x2F;raspberry-pi-compute-module-4&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;blog&#x2F;raspberry-pi-compute-module...</a>[2] <a href="https:&#x2F;&#x2F;www.jeffgeerling.com&#x2F;blog&#x2F;2020&#x2F;raspberry-pi-400-teardown-and-review" rel="nofollow">https:&#x2F;&#x2F;www.jeffgeerling.com&#x2F;blog&#x2F;2020&#x2F;raspberry-pi-400-tear...</a>

for some reason I thought the title was Raspberry Pi $400 Desktop PC... but it&#x27;s only $70

Awesome!I didn’t know that Raspberry Pi had these.I will definitely be ordering one.I do already own a newer Raspberry 4 with 4Gb of RAM and the massive heat sink is a must!
These things run WAY hotter than the Raspberry Pi 3’s.There are heat-sinking cases made of aluminum made by third-party’s that dissipate the heat almost as well as the turbo fan setups.

The Pi4 is a great piece of kit, and I love the idea behind this, but for me personally I really need to see all USB3 on it. I have some high speed peripherals that require it, and using a hub doesn&#x27;t work.

I think an existing RPI 4 in one of the many available cases would do what you need there. It already has bluetooth built-in.

Yep! A Chromecast running Linux basically

&gt; Gosh... if they had made this as box that connects to display and talks to any bluetooth keyboard then this would be gold.That&#x27;s basically the existing RPi desktop kit minus keyboard&#x2F;mouse (RPi, case, power supply, HDMI cable) — it does bluetooth OOB. Which you have been able to get for a long time.So, they already did it. This is a new, extra thing.

Gosh... if they had made this as box that connects to display and talks to any bluetooth keyboard then this would be gold. Requiring wired keyboard is such a let down and limiting. I would then connect it to my 4K smart TV and also use it as full blown computer! With dedicated app, it can turn any TV to smart TV, picture frame etc with unlimited customizations. It would be like Chromecast on steroids, open programmable OS and a keyboard!

There are Bluetooth &quot;DACs&quot; that have tube-based amplifiers so you can really go nuts with a DAC that costs like 5 times the cost of the RPi 400.

Monitors with 3.5mm outputs however are not that rare.

A super-cheap USB soundcard is another option albeit an ugly one. But I do agree it&#x27;s a shame they couldn&#x27;t squeeze an audio output into the design somewhere.

I noticed that. Audio has to come from the HDMI connection or from Bluetooth, either of which will produce better sound than the standard Pi audio jack. I imagine they see this being used with a TV, much like the old classic 8-bit consoles.

You can use a USB audio dongle. Just to take one example, the Apple USB-C audio dongle is only $8 and has extremely good measured performance: <a href="https:&#x2F;&#x2F;www.audiosciencereview.com&#x2F;forum&#x2F;index.php?threads&#x2F;review-apple-vs-google-usb-c-headphone-adapters.5541&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.audiosciencereview.com&#x2F;forum&#x2F;index.php?threads&#x2F;r...</a>

How do I play sounds with this? I see no jack for speakers or headphones. I assume one could have sound over HDMI but monitors with built-in speakers are not very common.

I like how the GPIO headers are right there in back by all the other usb&#x2F;hdmi&#x2F;ethernet ports.

It does, but it would hardly look worse if it were wider. It would break no canon either - e.g. Amiga had the same form-factor but with a full-size keyboard incl. keypad.

I personally think this product looks awesome, maybe partly nostalgia.

There is a heatsink. It&#x27;s a large chunk of metal under the keyboard.

It has a massive heatsink inside of it, it&#x27;s passively cooled but it&#x27;s a big chunk of metal the size of the keyboard, which is more than enough for this chip.

I can also see no reason why does it have to be this small (I would appreciate a keypad) and why is there still no heatsink.

They should offer the case&#x2F;keys in more colors. I have the black keyboard and it&#x27;s nice beyond anything I could expect at that price range.Anyway, if they make the board available separately, there can be a huge ecosystem of interesting cases for it.

Yes the form factor reminds me of my first computer, a Commodore 64.

I&#x27;ve ordered one, it arrives tomorrow, and until I read your comment I had overlooked the book.When I was younger, I was lucky enough to have an Amiga Commodore 500+, and I read all the included literature cover to cover, over and over again. I have a lot to thank those manuals for!EDIT: It&#x27;s available for free online as a PDF, <a href="https:&#x2F;&#x2F;magpi.raspberrypi.org&#x2F;books&#x2F;beginners-guide-4th-ed" rel="nofollow">https:&#x2F;&#x2F;magpi.raspberrypi.org&#x2F;books&#x2F;beginners-guide-4th-ed</a>

Absolutely wonderful! This is getting ever more close to the joy of the original home computers, and a great setup for a kid to start with especially with the book provided. The RPi4 is also an impressive bit of kit. Bravo RPi foundation!

Wow. This would work awesome for distributing Apps that require hardware, for example Point of Sale Systems.

Missed opportunity to use the Compute Module 4 and full-size HDMI ports.

I&#x27;m hoping some company takes the new Compute Module 4 and does that. Would be great as a thin client + browser only machine.

I guess this is why I was down-voted at first, but it really isn&#x27;t a laptop if it doesn&#x27;t have a screen and I don&#x27;t need one. I think we will see hacks with the pi 400 soon that will have a battery anyway, or one can just disassemble it and attach a power bank to it anyway so I guess the solution is already there.

At that point they may as well make it into a laptop.

I&#x27;m curious how you plan to use it wirelessly if you need to plug it into a monitor anyway? Do you also have a mobile monitor?

This is so good, I work from home and I&#x27;ve been eyeballing products like this for a while but until now its all been 3rd party. What would really take the cake for me is if they made a version of this but with a battery and wireless charging, then this really would be an exceptional portable desktop pc.

Sadly the 400 lacks the audio socket that the 4B has :-( so audio out is only available over HDMI or Bluetooth.You can probably power it from a USB battery pack quite nicely.

If there was a way to attach a battery to this, and possibly an external speaker, this would be a pretty cool setup for a notetaker for the blind.We had talking and braille notetakers (basically our equivalent of PDAs), years before the rest of the world heard about such devices. They&#x27;ve been falling out of fashion lately, mostly because they&#x27;re so expensive, compared to cheaper but slightly worse alternatives like laptops. If we could make one based on a Pi 400, though, it would probably be way cheaper than anything else on the market, and way more powerful, considering we can put Linux on it.

There is no eMMC or other internal storage option on this PC. Just a microSD card slot and USB.

So what are the storage medium options for this device? I&#x27;m not much of a Pi-guy; some comments mention &quot;eMMC&quot;; can that actually be used? Why and how would it be better than an SD card?

Access to Internet, thankfully and recently, has become super affordable by my own standards to give away. I have a 100Mbps fiber from Airtel (I have US&#x2F;Europe calls all the time) at around USD 15 (INR 900) &#x2F; month. I could easily get another for the cafe.Rent for a small garage would be about USD 35 &#x2F; month. Electricity would not cross USD 50 &#x2F; month.

Is it really an affordable situation with the current pricing of the RPI to setup a computer cafe for the kids who don&#x27;t have access to the computers and internet ?

I don&#x27;t know why you&#x27;re downvoted.This is exactly how it&#x27;s done in many places. A 10yr old computer is perfectly fine for this, maybe even older. Yes it might not play all youtube videos, but it works.

&gt;One local school here threw away 50+ small dell quad-core i5&#x27;s in their quest to make sure they spend their money wisely.I think broad computer illiteracy in the general population has convinced people that you &quot;need&quot; a new, powerful computer. In reality, 95% of the population can get away with any decent computer from the last 10 years. Grandma isn&#x27;t training a neural net, she&#x27;s checking Facebook.I continue to use a 2nd generation i3 desktop as a &quot;daily driver&quot; for a lot of my computing&#x2F;server needs, without issue.

how did you find out about the local school throwing away 50+ small dell quad-core i5s?

Electricity utilization is another dimension. A Pi can run off batteries or a hand crank in the worst case.

A few months back I literally found a computer by a dumpster in the rain. It was some corporate castoff from a local investment firm. I brought it in, dried it off, let it dry thoroughly for a few days, and examined it, and the innards looked to be brand-spanking-new with no rust or damage in sight. After installing a hard disk (its original hard disk was removed and presumably erased or shredded), it was ready to go.It&#x27;s a pretty sweet machine too, an HP Elite 8300MT from about 2012 or so. It has one of those side panels that can be removed by working a latch with your hand -- no screws necessary. I&#x27;m making it into a build server.

I agree with you and I want to look into that too. But I am not sure it would be easy to order such computers, in working conditions, as easily as this RPi. If the logistic hassle is too much, it might not take off at all.

Old Computers are usually rather big, heavy and a bit limited in their ability in terms of interfaces. Like they often have no sd-card-slot, bluetooth or wifi. And yes, they need more power.This RP400 is small, can be taken everywhere by kids, has all necessary interfaces to make something funny and can on worst even run from a manual energy-source (which of course is more relevant for a poorer country than a rich country).I can see kids taking this RP400 around like a (paper)notebook, work with them at school, home, their friends home or somewhere else and motivating them to use them more than some stationary device. And because of the hdmi they even can switch places fast if neccessary, limiting the interuptions in their work.

&gt; E-waste is a massive problem nowadays. Why not assemble the lab out of &quot;old&quot; computers? They might take a bit more electricity to runIn the developing world electricity tends to be very scarce. Raspberry Pis, and stuff of that sort, are ideal for that environment.

&gt; They might take a bit more electricity to runBut how much more? Just &quot;a bit&quot; or a significant amount?

I like what you do and why you do it; do you have a blog or website?

E-waste is a massive problem nowadays. Why not assemble the lab out of &quot;old&quot; computers? They might take a bit more electricity to run, but, at least in the US, you can get truckloads of computers that were destined for the scrapyard, for free.One local school here threw away 50+ small dell quad-core i5&#x27;s in their quest to make sure they spend their money wisely.I&#x27;ve assembled a small lab, with many computers, laser printers, scanners, tablets, projectors, big-screens, etc. Without spending a single dollar on hardware.This has two effects, it reuses a resource that was destined for destruction, and it doesn&#x27;t add fuel ($$$) to the ecological dumpster fire that is modern capitalism.

As an engineer&#x2F;founder from India who dreams of access to the Internet for everyone on this planet, these are the efforts that make me smile.I am in the process of sorting out my financial situation - tough founder luck. But I am happy to order a few of these (and monitors) and rent a small garage to give local kids a free computer lab to learn. (Kolkata, India)
