Title: Raspberry Pi's $35 Linux PC
Post by: Arizona Hot on June 14, 2012, 12:32 PM
Will the nostalgia of playing with now antediluvian technology (see Things your kids will never know - old school tech!  (https://www.donationcoder.com/forum/index.php?topic=15415.0)) make the Raspberry Pi (http://www.pcworld.com/businesscenter/article/253857/raspberry_pis_35_linux_pc_hits_the_streets_at_last.html) a sucess?
Another nostalgia article? (http://www.nytimes.com/2012/05/31/technology/personaltech/daddy-what-are-turntables-eight-tracks-and-floppy-disks.html)

Ummm... I'll take 2? :P

At that price... sheesh... You cannot go wrong.

EDIT:

Odd... Page won't load for me... http://www.raspberrypi.org/ seems down for me (and just me)... :(

EDIT 2:

Well, can't buy it, but registered interest.

 ;D  These have been on back order for months. 

I think I ordered mine in Feb.  It's due to arrive this month.   One of the guys @ work had his in the office the other day.  It was running XBMC.  Pretty neat.  ;)

Got mine - it is picky about USB devices. Can't get a wireless keyboard/mouse combo to work (even with a powered hub) - had to buy a cheap no-frills USB keyboard and mouse.

If you haven't got all the bits you need then you find it isn't as cheap as you thought.

Note it comes uncased (they are going to supply cases shortly if you want one) - so you have a bare board sitting on your table and getting hot!

You need:

HDMI or yellow-phono video capable monitor (HDMI carries audio too so an HD TV Is a good option)
Monitor/TV cable
USB mouse and keyboard (you may have more luck than me but it didn't like the cheapest MS Wireless Desktop set I could buy - deliberately bought this to limit the number of USB sockets required!)
Ethernet cable (also required to set the clock correctly as no BIOS or RTC battery)
If you aren't using an HDMI monitor/TV with speakers then you need speakers or headphones with jack lead.
Fast SD card (ideally class 10 to load with a Linux image - this is the main drive so you need the fastest you can get otherwise it is VERY slow)
Power supply (you need something like a Blackberry charger with a mini-USB connector). You can't power it from a USB socket on your computer!

If you want additional storage an external USB hard disk (in which case you also need a powered USB hub as there are only two USB sockets)

Note there are Linux images available from Raspberry Pi website. The recommend one (a Debian Linux) is not overly impressive out of the box. Very few apps preinstalled - mostly educational programming apps without manuals. One is included and if you want the manual you have to buy it from the developer! Also painfully slow (even with a class 10 card) - so much so that the browser included (Midori) frequently times out loading pages.

Not sure what apps can be installed without needing to be recompiled because it is ARM based.

All in all it is a bit of fun - but actually not that cheap if you have to kit it out (if you have a junk cupboard full of suitable bits you are OK), and performance is a bit underwhelming.

Given that there are a number of similar projects on the threshold I think I wish I had waited to see how it all shakes out.

Well, can't buy it, but registered interest.

You can also register at RS Components (Australia) (http://australia.rs-online.com/web/generalDisplay.html?id=raspberrypi), it'll be AU$41 delivered, cheaper than Element 14 (http://downloads.element14.com/raspberryPi3.html?isRedirect=true) - (formerly Farnell and the 14th element is Silicon in case you're wondering :) ).

The queue must be mighty long, I registered a while ago and so far they've invited two lots of 4000 to order.....and I wasn't one of them.

Your Raspberry Pi Id number is 244205

Or I could get one from ebay (http://www.ebay.com.au/sch/Desktop-PCs-/179/i.html?_nkw=raspberry+pi&_catref=1&_fln=1&_trksid=p3286.c0.m282).....

Only selling as I don't have time for the project I intended to use it for.
I ordered 2 of these with hopes to use them together for a project but I am no longer going that route.
I don't really have a need for it...

Yeah, right....

Don't know if anyone cares, but the Rasberry Pi community has their own monthly e-magazine. Called The MagPi, (http://www.themagpi.com/) it's now up to the second issue and may be downloaded here (http://www.themagpi.com/).


The MagPi: a Raspberry Pi community magazine
Posted on May 5, 2012 by liz   

Whenever I’m tasked with chatting up potential donors, partners or volunteers for the Raspberry Pi project, I’m asked what really makes us stand out from other computer companies. There are lots of answers: the charity business model; the unusual price point we’ve picked; the open-source software; the transparency about process; the focus on education.

But for me, what I consider the biggest thing we have going for us, and the thing I tend to rattle on about most in meetings, is the community that’s grown around the project. The MagPi, a free online magazine dedicated to the Raspberry Pi, whose first issue was released a few days ago, is a perfect example of that. It’s been put together entirely by volunteers, guided by Ash Stone, Jason “Jaseman” Davies, Meltwater and other names you may recognise from the forums and comments on this site. I was broadly aware they were up to something, but I was amazed at the scope of what they sent me to look at earlier in the week, and I’ve been really, really impressed by the first issue. There are Debian and Puppy guides, articles on computing history, ideas for robotics projects, tutorials in Scratch and Python (with code you can type in yourself, just like in the good old days), features about the Raspberry Pi itself, and other goodies to dig into. I really can’t recommend it enough, and if you haven’t been lucky enough to get to the head of the queue, you don’t need a Raspberry Pi to find it useful (you might actually find the magazine good preparation before yours arrives). So go and download a copy, have a flick through, write to the guys if you think you can contribute to future issues, and let us know what you think!

Was that going to be $10 a week? :)

I would have registered a while back if I knew that they were this hard to get. Yikes. I figured that I would be able to just go out and get one whenever I felt like. But this works too -- gives me some time to contemplate what wonderful things I'll accomplish with it~! :D

Something just occurred to me. Those of you who have been around long enough to have witnessed the birth of the "personal computer" (Kim1, IMSAI, etc.) and lived through it's early childhood (VIC-20, C-64, Atari 800, Coleco Adam, TRS-80, Apple ][ at al) might notice a similarity between then, and what's happening now with the Rasberry Pi.

You're seeing a creative community of enthusiasts forming around a piece of inexpensive and empowering technology. And this community is open to new ideas and freely sharing discoveries with each other.

Looks like the "good old days" of the personal computing movement are making a comeback.

Funny how Apple and Microsoft got their start in a time when there was a huge interest in getting control over your personal technology. Bill Gates, Paul Allen, Steve Jobs and The Woz launched two of the most successful companies in history - and ushered in a whole new world (both figuratively and literally) - in rebellion against IBM and other computing giants who were committed to preserving their secretive and proprietary walled-garden ecosystems.

Things have changed a lot since 1975. And one of the most notable changes is that the former 'rebels' are now doing their damnedest to become our new overlords.

How interesting that a new small, inexpensive, single-board computer has emerged, along with it's own community, in response.

Apparently history is repeating itself - once again.

How cool is that?

----------------------------------

Addendum:

Back in the day, I was firmly ensconced in the Commodore Camp with my trusty Vic-20, my stable of C-64s and my elegant C-128. Our holy book was a Canadian-based enthusiast's magazine called Transacter. It started out in 1978 as a few page newsletter. But it became a legitimate printed bi-monthly magazine sold on bookstore racks and the bigger news stands before its demise in 1989.

Since there were no websites back then, it was eagerly awaited by the Commodore community whenever it came out. The B&N around where I live used to have a sign that read: "ATTENTION! Transacter magazine is put out as soon as we receive it. If you don't see it, it either hasn't arrived, or it's sold out. And no - we won't be receiving additional copies."

The full Transacter archive in PDF can be found here (http://www.csbruce.com/cbm/transactor/). If you're curious, take a look at a few issues and compare what you see there to what's happening with MagPi magazine.

Of course, if you still have an old C64 sitting somewhere, you could always plug it in (I can almost guarantee it still works), download a few copies of Transacter, and have at it. Well worth it too! That old C64 sprite and SID chip magic is still there.

@Renegade - Arduino is already established and well beyond the curiosity/novelty stage. Not a bad choice if you're looking to develop something that has an active audience. You can also think outside the box with this puppy. Some musical instruments (http://arduino.cc/playground/Main/ArduinoSynth) are out there that use Arduino for their base hardware. Ditto for some audio realtime processing (http://interface.khm.de/index.php/lab/experiments/arduino-realtime-audio-processing/) uses.

Might be a natural for you since you're into music apps already. Just a thought... ;)

Well, having looked some more, it's not quite what I want to work with. I'm really looking to work with an OS already there so I have a solid set of tools to work with, rather than having to go and code them all from scratch. I just don't have the time, unfortunately. I'd love to do it, but... time...

Any suggestions for one that runs Linux? That would be perfect. Or even Windows... though not really too hot on that idea as I don't really want to pay licensing fees like that.

Just to very briefly risk risk going semi-off topic, there's two interesting articles over on the Phoronix website detailing the construction of a 12-core and a 96-core ARM cluster using inexpensive Pandaboard (http://pandaboard.org/) singleboard computers and Ubuntu. I think it serves as real world proof of just how much can be done with these little computers and an open operating system. Like famous burlesque dancer Gypsy Rose Lee allegedly said: "It ain't how much you got. It's how you use it."

And lest we be too jaded, the 96-core cluster not only draws a relatively paltry 200 watts for the entire works - but the techno-wonks responsible for it decided to run it off a solar panel. Small surprise it's MIT where this is all happening, right?

Note: Using an industrial trashcan as the server rack was inspired AFAIC.  >:D (The 12-core used a wooden dish drying rack.)

[ You are not allowed to view attachments ] [ You are not allowed to view attachments ]

Last week I shared results from the Phoronix 12-core ARM Linux mini cluster that was constructed out of six PandaBoard ES development boards. Over the weekend, a 96-core ARM cluster succeeded this build. While packing nearly 100 cores and running Ubuntu Linux, the power consumption was just a bit more than 200 Watts. This array of nearly 100 processor cores was even powered up by a solar panel.

This past weekend I was out at the Massachusetts Institute of Technology (MIT) where this build took place. A massive ARM build out has been in the plans for a few months and to even get it running off a solar panel. The build was a success and by Sunday, the goals were realized.

Here's the links for the 12-core (http://www.phoronix.com/scan.php?page=article&item=phoronix_effimass_cluster&num=1) and 96-core (http://www.phoronix.com/scan.php?page=article&item=mit_cluster_build&num=1) articles if anybody's interested.

So... is Linux "just a hobby" as another forum thread recently asked?

Ummm... Apple was doing the same thing back then, i.e. Franklin Ace, Laser, and other clones.  They did it again in the 90s.  This is just part for the course for them... they never were truly rebels.

I do,I do!!!!

Nicholas Wirth's magnum opus. I never got my head completely around it. Probably because I can't walk and chew gum at the same time. Modula-2 and Modula-3 are another story. I still thought that Modula was one of the finest general programming languages ever created. And the only one (other than FORTH) I was ever really comfortable using now that I think about it.

Now all we need is some Linux software to take advantage of that amount of horsepower!

There's quite a bit actually. A lot of Blender and other enthusiasts have built their own personal render farms for ray tracing, CGI, and 3D modeling. In the professional world it's a given to own a render farm. A Google search will spot you plenty of choices. One of my clients uses a commercial package called Deadline running under CentOS to handle their rendering admin, mainly because it has out-of-box support for over 20 of the big 3D apps such as Maya, Blender, 3ds MAX, etc. You can get a free 2-node copy here (http://www.thinkboxsoftware.com/deadlineoverview/) if you're curious or have an immediate use for this sort of thing. (I certainly don't. <*grin*> ) Deadline gets a little expensive once you go beyond that however. There's also equivalent freebies and other open source packages (and how-tos) out there if you look for them.

Excellent point although that was primarily Apple busting down on the clones for duplicating their ROM chips. Not reverse engineering (at least at first) either. They were reading out the chips and then reburning them IIRC. But Apple has gone way beyond that with their current legal arguments because they're now claiming ownership of paradigms and raw concepts - most of which weren't their inventions or discoveries to begin with.

And true, also that Jobs never really was. Woz maybe. But he got double-shuffled out of the picture once Jobs gathered a bunch of brilliant software and hardware people together to create the Macintosh - and then claimed the whole thing as his own personal invention.

What I find  amazing is that nobody ever really seriously called him out on that. And now, it's generally accepted "fact" that Steve Jobs created the Macintosh.

Love it! (not)  :-\

[Continuing the aside}

Blimey I had completely forgotten about Modular! A blast from the past - and yes it was a great Pascal-like language.

I do remember having fun with Forth - though it seems less like high level programming and more like a cross between a Mensa logic puzzle and assembly language!

-Carol Haynes (June 21, 2012, 11:57 AM)

Sorta. They did call it a mid-level language. And with good reason. FORTH's methodology is weird by today's standards. But for real-time controllers and things that interfaced with the real world you couldn't beat it. Especially with the limitations and clock speeds of the 8 and 16-bit hardware you had to work with back then. It screamed on a Zilog Z-80 chip. I used to run it (FigFORTH) on my C64. It was a lot easier than writing 6510 assembly via HesMon. You could program some pretty cool things for the SID music chip that way.

FORTH still has its supporters. And it's still used to this day. Last I heard there was a version of it you could run on an Arduino. My understanding is it's not a difficult environment to port. The core kernal is tiny. Most of FORTH is written in FORTH. And if something you wanted wasn't a part of the language, you could always add it yourself fairly easily. Much easier than trying to master an "everything plus the kitchen sink" framework like Net or Mono. Sleeker and much easier to understand too. That's one major reason FORTH became so popular for a while. You could engineer your own private FORTH-based language if you wanted to. ( Same went for Modula now that I think about it.)

at the risk of going off on a tangent (HA!) these little boards have caught my attention of late, and I would like to learn a bit more but I don't know where to start

Can anyone recommend some good introductory resources - web based stuff is good, but good books would suit me better

EDIT: I'm guessing as total noob that arduino is probably a good pick, but I'm open to advice from all you experts...
Title: Re: Raspberry Pi's $35 Linux PC
Post by: 40hz on June 26, 2012, 05:20 AM
^Which board you should pick will depend on what you want to accomplish.

The Arundino is probably best suited for gadget and controller type projects. There's a huge hobbyist community in love with the thing. And for good reason. It's probably the best documented of all the tiny PCs because of that interest. A quick check of Amazon will point you to several books that are available for it. Make magazine does quite a few Arundino based projects, and there's lots more on the web.

If you're looking more for a small form factor general purpose PC, something like the PandaBoard is a better choice in that it can run most flavors of Windows or Linux. So anything that applies to those operating systems will apply to the board as well.

The RasberryPi is very much like the PandaBoard except it's more stripped down and less ready to go straight out of the box. However, that makes sense as it was designed to be a learning/experimenter's board. And now that it's shipping, a very active community seems to be developing around it. If they can get the manufacturing backlog straightened out I think it will eventually become as popular as the Arundino. From what I can see there's only one real book available for it called Beginning Rasberry Pi (http://www.amazon.com/Beginning-Raspberry-Pi-ebook/dp/B008C4JLZG/ref=sr_1_2?s=books&ie=UTF8&qid=1340705731&sr=1-2&keywords=raspberry+pi). It's only available as a Kindle edition (hmm...is this the shape of things to come?), but I suspect there will be other titles out shortly.

So...what's best?

Depends on what you want to do. :)

^Which board you should pick will depend on what you want to accomplish.

I was leaning toward the arduino for this very reason (I have a small robotics project in mind).  I've done a bit of research, and as you say there are any number of resources available, but as this is potentially a very complex subject I guess I was looking for a recommendation of a good entry point.  I've read some of the make stuff and it's not really what I was looking for (it was more 'insert tab a into slot b' type of stuff).

You could connect multiple Arduino together using it's I2C bus, ethernet or GPIO.  Using the Arduino Nano (http://arduino.cc/en/Main/ArduinoBoardNano/) you could possibly break down a complex project into a set of discrete modules.

:( Still waiting here... Sometime in August I should get them... Ordered 2 as shipping was almost $15, so figured I might as well get free shipping and buy 2.

But I am pretty excited to get them! :D I've already got some plans in the works for it, and am currently going through some of the learning curve for some new programming techniques and whatnot that I'll be using once I get them in August. Crossing fingers and hoping that this all works out...




So, anyone care to disclose what they're planning for their Raspberry Pis?

We waited 4 months.  Ordered my Raspberry Pi in March, got it two weeks ago. Works great.  I am using an old Motorola phone charger to power it, HDMI to our 60' LCD TV, Fedora remix on it.  Will get around to putting XBMC on it sometime this weekend I hope. I ordered it for my 14 year old, he is in charge of it.

We cannot get wireless to work on it.  Tried several adapters.  I just ran another 20 ft. Cat6a to it. It is also finicky about USB keyboards with USB hubs built in.  Tried Razer and Kensington keyboards, it will not recognize them. throws an error about not being able to reset USB port 6 or 8.

Other than that, browsing the web on it is ridiculous fun.

I've got mine running XBMC (OpenELEC version http://openelec.tv/news (http://openelec.tv/news)) and it's great!
It plays videos and FLAC files from my network, and works fine with the Lenovo HTPC Keyboard Remote (wireless trackball and keyboard).
I also got this laser cut case: http://builttospecstore.storenvy.com/products/404262-raspberry-pi-enclosure-kit (http://builttospecstore.storenvy.com/products/404262-raspberry-pi-enclosure-kit), which gives it a finished look.

For my basic HTPC needs, it's perfect - tiny, dead silent, and it runs from a cellphone charger.

Thanks!  Writing to the SD now.  :Thmbsup:

Working.  A couple of questions though:

I would like to change the weather temp to Fahrenheit from Celsius, cannot find anywhere to do that.

I would like to add my SMB root folder, and have it scan all subfolders for music, video and photos... D:\music\albums\a\artist folder\songs (example)

I cannot figure out where to set the time, it is incorrect.

You have no idea how much your help is appreciated!
Title: Re: Raspberry Pi's $35 Linux PC
Post by: ebs on July 12, 2012, 12:54 PM
To change between Celsius and Fahrenheit go to  Settings -> Appearance -> International  and select your location under "Region".
Not at all obvious, is it? I think this one sets the correct time zone as well.

I added my NAS SMB folder by adding a location like this: "smb://192.168.2.21/music". This lets me browse all my music in the alphabetical subdirectories.
Something similar should probably work for you, but you may want to create a public shared folder on your PC if you can't get it to work directly.
Obviously, you should also change the IP address to match your PC. I tried to use the name "NAS", which is how every other device sees it,
but I couldn't get that to work, so I just used the IP address.
Title: Re: Raspberry Pi's $35 Linux PC

Already compiled Quake3 on it and had a play, now it's off to get the LAMPi (http://www.lampi.co.uk/) going so I can repurpose the XP web server to something else.

If anyone is interested in a plastic case for the Pi I got one of these:

http://www.lmw.co.uk/shop/index.php?main_page=index&cPath=28

Nicely done, with a click fit shell (no tools) so it is easy to take apart and put back together.

If you want to use the IO pins on the board they are not exposed but all the sockets fit well and it feels a lot less like you might break something than using the bare board!

UPDATE: They do seem to have a red version which has the main IO port exposed - but I have a black case which is fully enclosed.

Ok...something I've been waiting to see happen has happened!

They have built a supercomputer out of Lego blocks and 64 Raspberry Pi boards. It has a total of 1TB of RAM (via 16Gb SD cards installed on each Raspberry Pi); and it runs on standard AC mains power. Cost is about $2500 for the hardware. All software was obtained from F/OSS sources.

Awesome!

You can read more about it on the phys.org website. Link to the full article here (http://phys.org/news/2012-09-raspberry-pi-supercomputer.html).

Professor Cox and his son James with the Raspberry Pi supercomputer


Engineers build Raspberry Pi supercomputer
September 11, 2012

(Phys.org)—Computational Engineers at the University of Southampton have built a supercomputer from 64 Raspberry Pi computers and Lego.

The team, led by Professor Simon Cox, consisted of Richard Boardman, Andy Everett, Steven Johnston, Gereon Kaiping, Neil O'Brien, Mark Scott and Oz Parchment, along with Professor Cox's son James Cox (aged 6) who provided specialist support on Lego and system testing.

Professor Cox comments: "As soon as we were able to source sufficient Raspberry Pi computers we wanted to see if it was possible to link them together into a supercomputer. We installed and built all of the necessary software on the Pi starting from a standard Debian Wheezy system image and we have published a guide so you can build your own supercomputer."
.
.
.
< Read the rest of this article here (http://phys.org/news/2012-09-raspberry-pi-supercomputer.html).>

As was noted in the above article, Professor Cox was also good enough to provide full details (available online or via PDF download) (http://www.southampton.ac.uk/~sjc/raspberrypi/) so you can roll your own if you're feeling ambitious.

I don't know what's more impressive: the fact they built this thing - or that they were able to score 64 Raspberry Pi boards to do it!

Lots of fun with the little machine.
I plan to use one in place of a '06 iMac that's now used only to run some old DOS apps (!).
DosBOX seems to run fast enough on the Raspberry Pi.

Got it for just north of $100, and I have a full fledged machine... a good option to think about if you can find it for that price.

^Yeah. I'm tired of being on a waiting list twice now. (The first time after, waiting three months, my order apparently vanished without a trace and I had to get back at the foot of the queue again.) I may just break down and order an ARMBrix Zero or a MarsBoard instead. I primarily wanted to get the Pi because I wanted to support their initiative. But I guess I could always just send them a donation.

Since Logitech had decided to kill the Squeezebox some months ago, here's another great use for the Raspberry Pi. Fire up Squeezelite (https://code.google.com/p/squeezelite/), and you have a perfectly functional Squeezebox "clone". If you actually don't want any compromise regarding the sound quality, add a cheap USB sound card with a digital out (or an HDMI audio splitter), and the stream is ready to go in a pricey DAC and to the rest of the sound system.

The damnable thing about this video is that it only describes what CAN be done, without actually showing it BEING done.  He hooked up the video screen to a DVD player, not the Raspberry Pi.  He showed the battery can run a motor, not a Raspberry Pi.  He showed a disk drive and an mp3 player, saying they both can be used as external storage, without ever showing HOW.  
And then, the best part... he talked about how discussion was going to go on at a forum topic... with a bit.ly link in the video, not the description, where it would actually be useful... that doesn't go to a Raspberry Pi discussion forum.

Glassgow University built a cloud platform from Raspberry Pi's and Lego
Thursday, June 13, 2013


The University of Glasgow has created a working model of a multi-million pound cloud computing platform using Lego bricks and Raspberry Pi mini-computers.


The project, which is called Raspberry Pi Cloud, is the idea of four lecturers at the University’s School of Computing. The four doctors believed that the knowledge about the cloud will play a very important role in their students’ future as IT professionals. But it was hard for researchers and students to develop a good practical knowledge due to the secrecy nature of how cloud computing infrastructure works.

According to one of the lecturers, “For an initial investment of less than £4,000, we’ve been able to build a Linux-based system which allows researchers and students complete access to a working cloud computing infrastructure at a tiny fraction of the cost of its commercial equivalent,”

$199, 4.2” computer is Intel’s first Raspberry Pi competitor  Ars Technica (http://arstechnica.com/information-technology/2013/09/199-4-2-computer-is-intels-first-raspberry-pi-competitor/)

Oooh! Interesting!

It's notable that the MinnowBoard is an open hardware platform, a distinction that Arduino and BeagleBone can claim but Raspberry Pi cannot. Users could create their own MinnowBoards by buying the items on the bill of materials—all the design information is published, and CircuitCo chose components that can be purchased individually rather than in the bulk quantities hardware manufacturers are accustomed to, Anders said. Users can also buy a pre-made MinnowBoard and make customizations or create their own accessory boards to expand its capability.

And being an open hardware platform means that the source code of (almost) all the software required to run the platform is open.

That is a big plus. Especially from a large company like Intel.

In a keynote address, Intel CTO Dirk Hohndel told the LinuxCon crowd that the MinnowBoard was "specifically designed as the first open hardware board based on x86, and that allows you to build derivatives without an NDA. All the pieces are open and available, all the blueprints you need, all the source files you need. You can create your own embedded platforms without Intel, without any of the vendors involved."

There's just one exception: with the graphics processing unit, only the binary files required to drive the GPU are available, as the source code remains closed. Anders said that's a sticking point for some purists, but he's hoping that "as long as we continue to keep pressure on companies like Intel, Texas Instruments, and Freescale… eventually they'll see the light and say, 'we'll make these open as well.'"

The lack of transparency in the video drivers is, well, not great, but depending on what you're doing, it's unlikely to be a deal breaker.

Although it's more than four times the price of the BeagleBone Black, the MinnowBoard is also four or five times more powerful, according to Anders. "If you look at optimizing a few things, you can get it up to 10 times more powerful," he said.

The most likely use cases today aren't hobbyist applications but industrial uses, Anders said. "The BeagleBone is a very small, low-power device, and it's targeted for some very specific applications for hobbying. You know, developing small proof-of-concept designs," Anders said. "Our initial offer for the MinnowBoard is actually more targeted toward industrial automation, industrial controls. What you'll find is a lot of manufacturers, companies creating products, if they want to create an x86 design, they have to buy a third-party reference platform which is closed. They have to buy large software support packages, support contracts, and they generally don't get the right to use the existing design as it is. They have to buy additional licenses and things to create the product."

Meh, more on the market is good. It's not what I'm looking for, but looks like it has a definite market. Just not competing with the Raspberry Pi. :)

Why pay for a VPS when you can have your own server?

EDIS will colocate your RasPi for free at their datacenter in Austria. (http://www.edis.at/en/server/colocation/austria/raspberrypi/)

No bills apart from the initial RasPi purchase and mailing it to them, (unless you want it back).  They even provide free management including manual resets, (sometime within 72 hours).

Not bad if you just want a simple DNS, web server, proxy, VPN, etc and you have a RasPi sitting around doing nothing after the excitement has worn off ... now where have I put the damn thing ...

So mystery solved. For me this was just something that sounded fun to do with an RaspPi I have sitting around; I probably won't remember to follow up at the end of the month.  Maybe I'll check out the alternative RaspPi colo's mentioned - if they're really really cheap.

Techwise & chatwise I'm just not on the up and up with new developments (i.e. I've never even owned or used a cell phone before), but from skimming this thread it looks like the Raspberry Pi tablet does not quite have what it would take to use it as a replacement for my PC yet.
I have a full size mid-tower pc with AMD Athlon 64 X2 dual-core 4400+ cpu, Windows 7 Pro 32-bit, 4GB ram, and multiple HDs of 500 to 750GB, and an NVidia GTS 450 gpu.
When I see posts & stuffs like this, it makes me wonder when the day may come that I could swap out my box in place of a tablet to plug in my desktop mouse, keyboard, HDs, monitor, and headphone amp to my headphone & speakers. :)

PS - and do it for $35 (or shall we say less than $100).
PPS - One could use the tablet's onboard HD, and save the old HDs as backups.
Then the only power-hungry thing I'd have left would be my old 19-inch CRT screen; I wonder what the DPI is on those tablets?

Hey, I just passed 400 posts. :)

The Raspberry Pi isn't a tablet. It's a little credit card sized computer board (without a case). You have to provide your own keyboard, mouse, monitor, wifi, SD card, HDD, etc., if you want those things.

Also, the architecture (for Pi 2) is ARMv7, as opposed to x86 (or x86_64), which means you can't run Windows on it. And even though the Pi 2 will have some stripped down version of Windows 10 available for it, I suspect it won't be what you might think, (e.g., you probably won't be able to run any .exe file on it like you'd want to).

But if you were to install a flavor of Linux on something like the $35 ODROID-C1 (http://www.hardkernel.com/main/products/prdt_info.php?g_code=G141578608433) (Quad core 1.5Ghz, 1GB RAM) you just might have a nice little portable computer replacement.

Gives new meaning to putting a Pi in the microwave.

Some Dude Hacks Microwave, Puts Manufacturers to Shame  (http://ovens.reviewed.com/news/some-dude-hacks-microwave-puts-manufacturers-to-shame?utm_source=usat&utm_medium=referral&utm_campaign=collab)

Of course, nobody here would actually put a  Pi in the microwave. But, if you did you might get a Pi with superpowers(quantum?) like the Fantastic 4. Of course, you most likely would end up with something usuable only for Facebook (or AOL, if it's still around) like the Hulk, if anything good happened at all.
How about a container of liquid nitrogen? :)

The article says it will be able to use a version of Windows 10 from Microsoft. Would this ruin it?

Not sure why that would ruin it.

Sounds somewhat similar to being able to use Mathematica on the Pi.

Also, AFAICT, it's not just that you will be able to use a version of Windows 10:

The Raspberry Pi 2-compatible version of Windows 10 will be available free of charge to makers.

I'd agree.  They're taking advantage of a the fact that a lot of people don't know how mining actually works.

Hmm... I guess I missed the part where it comes with a custom mining chip. Some custom, specialized-for-mining chip might be pretty expensive.

As far as I understand, ASICs aren't necessarily ultra powerful machines. They just do one thing and do it really well, and do it even better in parallel/groups. So I suppose it's feasible that the custom mining chip can perform at a decent hash rate for a single machine, and is intended to be used with a mining pool or in large quantities (or both) if any actual BTC are intended to be mined from it. Unless there's something I'm fundamentally misunderstanding about how mining works.

But other than that, I kind of like the idea of using a little SBC as a non-mining, full Bitcoin node. It would be kind of like a PirateBox (https://www.piratebox.cc/).

That could be true. Hardware is better (way better) but sometimes a active community of developers are important.
Is useless have the cutting edge hardware with buggy software.
Maybe Odroid-C2 developers are dedicated but nothing compares with the HUGE raspberry pi community.

One thing I've been very foggy about for years is software compatibility between Unix-type systems. I guess drivers will certainly differ, but given a common CPU architecture (e.g., ARM processors), will software like RetroPie run on something like an ODROID?
Title: Re: Raspberry Pi's $35 Linux PC
Post by: f0dder on March 23, 2016, 10:16 AM
Keep in mind that ARM is not just "ARM" - there's several revisions of the CPUs, including 32- and 64-bit versions, support of "Thumb" mode (running 16bit code alongside 32bit code), and then the pretty varied platforms because arm i usually system-on-a-chip (i.e., not just a CPU).

I'm not sure about the level of compatibility, but for e.g. native code in Android applications (where you don't get to systems-level with drivers and stuff, but only add some native usermode code because of performance), afaik you have to compile for some number of ARM architectures to be able to use native code across a wide range of Android devices.

I just learned about ExaGear (https://eltechs.com/product/exagear-desktop/) which allows you to run x86 applications on ARM devices. It's kind of like qemu but supposedly has much better performance.

Combined with WINE, you may even be able to run some Windows applications on your little ARM device. :Thmbsup:

Hm, there's claims of 5x the performance of QEMU - that sounds pretty incredulous. I was under the impression that QEMU used dynamic code translation and was pretty fast, but I guess the translation involved in x86-on-arm might be lacking.
Title: Re: Raspberry Pi's $35 Linux PC
Post by: Deozaan on March 25, 2016, 02:01 AM
Perhaps that claim is based on the idea that QEMU has 5-10 times the overhead as compared to ExaGear, which uses binary translation? Honestly I'm not sure what these terms mean exactly. I'm just going by what I read out of the March 2016 Odroid Magazine article on ExaGear (http://magazine.odroid.com/201603).

I'm thinking of proposing a project based on one of these - or something like it - assuming what I'm after actually exists.

What I'm after is a Pi type mini device that is capable of running the Win10 IoT edition, that has 2 RJ45 Ethernet ports, and (preferably) some type of case that allows it to be discreetly plugged into the wall like a wall-wart power supply.

The purpose for this device is - or rather will be - to allow our Techno-Tarded sales staff to just pop this thing into the wall at a client location, plug a cable into it, and give us remote access to the network to monitor various pieces of equipment that are under contract.

The software part I'll most likely end up writing from scratch (I really hate me when I do this to myself), so I'm really just looking for hardware options at this point that will give us something that is small, cheap, and id10t simple for anyone to deploy. Because our IT staff - me included - is currently wasting far too much time running all over the %&$^ countryside trying to keep our current -(big name, fancy, basically shit)- "solution" running and reporting properly.

Is your customer going to be OK with that? I'm assuming you're only leaving it there temporarily, while the troubleshooting is going on? I'd be surprised if anybody is going to let you drop a device into their internal LAN.

Years ago we built an ESD solution for my employer (we sell computer HW and SW) according to requirements provided by several key customers. At the time, bandwidth was more scarce, and to conserve this, they wanted us to put satellite servers in their DMZ from which downloads could be streamed when authorized. That became part of the basic system architecture, but in the whole history of the system (over 10 years) exactly one customer (and that wasn't even one of the ones who demanded that feature) has ever let us deploy a device into their DMZ. And that's not even their internal network.

Back when I had the tolerance for stress to work on these, the client just wanted to be up, now.  I think it just depends on the type of client we're discussing.  If they're clients that outsource their IT, they won't know nor care- and I know this from personal experience.

Review: Odroid C2, Raspberry Pi 3, and Orange Pi+ compared (http://www.jeffgeerling.com/blog/2016/review-odroid-c2-compared-raspberry-pi-3-and-orange-pi-plus)

tl;dr: The ODROID-C2 is a very solid competitor to the Raspberry Pi model 3 B, and is anywhere from 2-10x faster than the Pi 3, depending on the operation. The software and community support is nowhere near what you get with the Raspberry Pi, but it's the best I've seen of all the Raspberry Pi clones I've tried

That would be more the type we're discussing. Also these are MSP contract customers that want/need us to monitor various pieces of equipment on their network. We already have a strictly software based solution that we're using, but it needs to be on a machine that is always on so it can do its data collection and reporting. However (SOHO/SMB) users being users, they're continually shutting down, crashing, or infecting the machine in question - not to mention the software in question is a bit finicky - causing us to have to chase down why network X isn't reporting anymore. Because a data set that's more than 8 hours old...is useless.

So I'm looking to create a small, clean, stable environment that it can run from to keep both sides happy and trouble free.

The level of interaction with the client network is actually very low -(SNMP only - at my insistence)- but it needs to be for us to effectively maintain the level of service that we're offering.
