A team at the free university of Bolzano, Italy, recently built MegaRPI, a cluster of 300 Raspberries!

Gives new meaning to putting a Pi in the microwave.

Some Dude Hacks Microwave, Puts Manufacturers to Shame

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.

Oooh! Interesting!

Quote

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.

Quote

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.

Quote

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.

Cubieboard 2 became available in June, (currently sold out at the Australian distributor - AU$89).

Quote

Specification
CPU：ARM® Cortex™-A7 Dual-Core
GPU：ARM® Mali400MP2, Complies with OpenGL ES 2.0/1.1
Memory：1GB DDR3 @960M
Storage：4GB internal NAND flash, up to 64GB on uSD slot, up to 2T on 2.5 SATA disk
Power：5VDC input 2A or USB otg input
Networking：10/100 ethernet, optional wifi
USB : Two USB 2.0 HOST, one USB 2.0 OTG
Extended Interfaces: 96 extend pin interface, including I2C, SPI, RGB/LVDS, CSI/TS, FM-IN, ADC, CVBS, VGA, SPDIF-OUT, R-TP, and more
Other: One IR

It can run Android 4.2 and since it already comes with a IR interface you can basically use it as one of those Android Smart TV gizmos, (HDMI output).

Quote

On the software side, cubieboard2 support both android 4.2 Jelly Bean, Ubuntu 12.04 and other Linux distributions.

This is not a persistence of vision screen saver, but it is a way to build the original device using a 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.

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 ...

Huh - now I don't even get an "Order now" button. The Free Raspberry Pi option is completely missing from the colocation ordering page now.

I wonder if it's because I'm in the US?

I think they've since cut back on some of their free offerings. And seriously, who wants to deal with the US when it comes to network anything these days?

FWIW a few other formerly free RP collocation services (PCextreme et al) are still reachable by US prospects. But they've since stopped offering freebies and now charge a small monthly fee.

I (in the EU) tried it not long after you did earlier (reply #109) and had the same result (disabled button)

Just had a reply to an email I sent them - EDIS is out of slots, but there was a glitch that allowed some orders to proceed. They hope to have more slots available at the end of the month.

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.

Sorry to get your hopes up

After all, that RasPi might be coming courtesy of the NSA ... StuxPi anyone?

Anyone has a project going with the Raspberry Pi that uses multiple temperature / humidity sensors on one Pi (and possibly other sensors reading environmental data)?

higher spec than the pi but with the same footprint so it could be a drop in replacement.

3 versions available starting at $45...

New Raspberry Pi Model B+

Quote

What's the same:

Same Broadcom BCM2835 Chipset
Same 512MB RAM
Same full size HDMI port
Same 10/100 Ethernet port
Same CSI camera port and DSI display ports
Same micro USB power supply connection

What has changed:
Now comes with 4 USB ports so you can now connect more devices than ever to your Raspberry Pi.
There is a 40pin extended GPIO so you can build even bigger and better projects than ever before. The first 26 pins are identical to the Model B to provide 100% backward compatibility for your projects.
Micro SD slot instead of the full size SD slot for storing information and loading your operating systems.
Advanced power management:
You can now provide up to 1.2 AMP to the 4 USB ports – enabling you to connect more power hungry USB devices without needing an external USB hub. (This feature requires a 2Amp micro USB Power Supply)
The B+ board now uses less power (600mA) than the Model B Board (750mA) when running
Combined 4-pole jack for connecting your stereo audio out and composite video out

Please note: The Raspberry Pi Model B+ is laid-out differently to the previous Raspberry Pis and existing enclosures and crusts (daughter boards) may not fit. Checkout the data sheet downloads below.

Chip: Broadcom BCM2835 SoC
Core Architecture: ARM11
CPU: 700 MHz Low Power ARM1176JZFS Applications Processor

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