Google AirShow streams IO live from several RC blimps

Yes, there’s a fleet of camera-equipped, remote-controlled blimps live-streaming a bird’s-eye view of Google I/O on YouTube, right now. It’s called Google AirShow and it’s taken over the airspace within Moscone Center. We briefly chatted with Chris Miller, a software engineer with AKQA (the company that put the dirigibles together for Google), about the technology used in each aircraft. It all begins with an off-the-shelf model airship that’s flown manually via standard a 2.4GHz radio. Each blimp is outfitted with a servo-controlled USB camera and 5GHz USB WiFi dongle which are both connected to a Raspberry Pi board running Debian, VLC and Python. A custom-designed Li-polymer battery system powers the on-board electronics. The webcam encodes video as motion-JPEG (720p, 30fps) and VLC generates a YouTube-compatible RTSP stream that’s broadcast over WiFi. Python’s used to pan the servo-controlled camera via the Raspberry Pi’s PWM output. The result is pretty awesome. But don’t just take our word for it — check out the gallery and source link below, then watch our hands-on video after the break.

Raspberry Pi camera module now shipping allowing HD video capture

One of the most interesting electronic components for DIY sorts and tinkerers to come out in a long time was the Raspberry Pi. That device is a small single board computer with just about everything you need for a myriad of different projects in one small footprint. The Raspberry Pi can also be expanded with a number of add-on boards and modules.

rpcam

Back in February we learned that a Raspberry Pi camera module was coming to market that would be priced at about $25. If the idea of a small camera board for your projects is exciting, you’ll be thrilled to hear that the camera board is now shipping. The device can be purchased at multiple online retailers, including RS Components and others.

The camera module sells for $25 and has a five-megapixel CMOS image sensor by OmniVision. That CMOS sensor uses 1.4 micron backside illumination pixel architecture. The architecture allows the camera to deliver five-megapixel resolution still images and high rate HD resolution video capture capability.

When the camera module is used record to 720p resolution HD video, it can do so at 60p. The camera card add on connects to the Raspberry Pi via the existing camera connector and uses CSI for data and I2C for control. Users can record both 720p and 1080p at 30 frames per second in H264 format.

The small camera add-on board measures only 20 x 20 x 10 mm and has an integrated flat ribbon cable for connection. The camera will work with both the Raspberry Pi Model A or Model B boards. Depending on the version of the operating system you’re using on the board, you may have to upgrade to be able to use the camera add on.

Raspberry Pi camera module comes to the UK May 14th, lands early for some (updated)

Raspberry Pi camera module comes to the UK May 14th, lands early for some

Remember that Raspberry Pi camera module we wrote about a few months ago? It looks like UK-based electronics retailer CPC / Farnell will start taking orders for the shooter on May 14th. Users on the Raspberry Pi forums who signed up for info about the camera module have received an email from the retailer inviting them to order. As a reminder, the five megapixel fixed-focus shooter — which only measures 25 x 20 x 9mm — can snap 2,592 x 1,944-pixel images and capture video at 1,080p (30fps), 720p (60fps) and VGA (60 or 90fps). While the accessory is expected to cost about $25, there’s no actual pricing details on CPC / Farnell’s website. Wanna see the camera module in action? One lucky Raspberry Pi user’s received the device early and shared a video — check it out after the break.

Update: As promised, the boards are now officially available to order per a blog post on the Raspberry Pi website. And the price is indeed $25. Hit the source link for a list of commands needed to activate the add-on, or check after the break for another video demonstrating the setup process and some PR explaining Element 14’s competition to promote the Pi and its camera.

Raspberry Pi Gets Water Cooling Solution

Raspberry Pi Gets Water Cooling SolutionThe Raspberry Pi is certainly one hot ticket item when it was first released, targeting hobbyists who want to build their very own computers without having to sell an arm and a leg. While this low-powered mini computer will run on a 700MHz ARM11 processor, one is able to obtain more performance out of it by overclocking it to 1GHz. Of course, if you want to go all out, then the processor might get wee bit unstable, but there is nothing quite like a custom cooling solution to bring down the heat a notch (or two).

Check out this water-cooled “Wet Pi” project that you see above, as it hails from bit-tech forum member Phame. Of course, in the first place, there is no good reason to make use of water to ensure that a Raspberry Pi remains nice and cool, after all, it will never notch up the temperatures that a high-end gaming computer would. Still, this is a fun project to dive into, and it is one of those “because we can” scenarios, where the custom case is equipped with neon-pink water pumped to three of the hottest spots on the board. The water pump itself will be powered by the Raspberry Pi board, so all you need to keep this system running is a single power adapter, now how about that?

The BeagleBone Black Is A New Single-Board Computer That Can Brew Beer

beaglebone-specs-640x444

While the Raspberry Pi is great for educating kids about computing, can it brew a mean beer? The BeagleBone Black can. Trevor Hubbard, an engineer at Texas Instruments, uses the new, next-gen board to control heat exchangers and monitors to handle beer temperature remotely.

The board itself is quite cool. It runs a AM335x 1GHz ARM Cortex-A8 processor with graphics accelerator and has two 46-pin headers for IO, making it ideal for monitoring and robotics. The board itself costs $45 and is available now.

It can run Android and Ubuntu linux and connects to the Internet via Ethernet or a USB Wi-Fi dongle. Interestingly, the entire board is open source, allowing you to download and tweak the design to suit your needs.

The company was founded by Jason Kridner and Gerald Coley, two TI engineers. The headers allow for multiple styles of input and output including serial connectivity, timers, and digital I/O. While not as inherently simple as the Raspberry Pi, it’s still a formidable board.

Hubbard, who recorded a video about his project, shows how he can control his beer temperature remotely using a BeagleBoard, the Internet, and a taste for bubbly hops. There is, I’d wager, not much more a man could ask for.

Where In The World Are The 1.2M Raspberry Pi Microcomputers? Mostly In The West – But Pi Founders Want More Spread This Year

rastrack

One to 1.2 million Raspberry Pi microcomputers have shipped since the device’s launch just over a year ago but where in the world are they located? While it’s impossible to say exactly where* each Pi has ended up, the vast majority of the devices sold to-date have shipped to developed nations — including the U.S. and the U.K. But the potential of the Pi as a low cost learning-focused computing platform for developing countries remains very exciting.

Last week the U.K.-based Pi Foundation blogged about a volunteer group that had taken a suitcase-worth of Pis to a school in rural Cameroon where they are being used to power a computer class. At $35 apiece, and even $25 for the Model A Pi, the Pi does a lot to break down the affordability barrier to computing — although it still requires additional peripherals (screen, keyboard, mouse) to turn it into a fully fledged computer terminal.

Asked about the global sales distribution of the Pi, the Foundation provided TechCrunch with some “very rough”, internal estimates of Pi sales to developing/emerging nations — and the figures (listed below) suggest that the first million+ Pi sales have overwhelmingly been powered by wealthier nations.

The most Pi-populous country on the developing/emerging nations list (India) can lay claim to roughly 0.5%-0.6% of total global Pi sales to-date, according to this data. While, collectively, these listed nations make up between only 1.4% and 1.7% of total global Pi shipments. So more than 98% of the Pi pie has been sold to the world’s wealthiest countries thus far.

India6000
Indonesia1200
Lao P.Dem.R.600
Malaysia3400
Philippines500
Pakistan100
Sri Lanka50
Thailand2000
Vietnam500
Egypt150
South Africa2000
Tunisia200
Zimbabwe50
Bolivia100
Chile400
Colombia20
Peru50

There are also, of course, scores of (apparently) Pi-less developing nations that do not make this list at all. One of which – the Kingdom of Bhutan — does actually have a princely one Pi sale to its name at present, according to the Foundation. “It’s a server for Khan Academy Lite in a school, whose 64GB SD card costs more than twice what the Pi cost,” the Foundation’s Liz Upton tells TechCrunch. “We’re working on getting more out there!”

It’s likely that some of the Pis shipped to developed countries have found their way to less wealthy nations – via charities and other ‘suitcase schemes’ such as the Cameroon school project mentioned above which took out 30 Pis. Or via individual buyers seeking to avoid high import tariffs that can push up the price of bulk commercial imports (such as in Brazil).

But even factoring in some extra spread, there’s no doubt the Pi is predominantly disrupting the living rooms and schools of the developed world. Which, it should be noted, was the original ambition of the Pi founders — specifically they wanted to get more U.K. kids coding, following a national slump in interest in computer science education.

But the Pi’s unexpected popularity has generated additional momentum for the project — and even grander geographical ambitions.

“We’re weighted very strongly towards the developed world,” admits Pi founder Eben Upton, when he sends the data, but he says that this spread — or rather concentration — is something the Foundation is keen to work on. “A major challenge for us this year is to find ways of making Pi more available, and more appealing, in these [developing/emerging] markets,” he says.

The Pi hardware seems to offer huge potential to the developing world — being cheaper than most mobile phones, let alone most smartphones — the other device touted as the likely first computing experience for connecting the “next billions” to the Internet. The Pi is also cheaper than another Linux-based low cost learning-focused computing project: the one laptop per child’s XO laptop. And it has an advantage over general Linux PCs or Android tablets in being conceived and supported as first and foremost a learning environment, making it well-suited to push into schools.

As for low cost PCs in general, the netbook category — still more expensive than Pi — is facing extinction by 2015, according to analyst IHS iSuppli, which has put out a forecast today predicting zero netbook shipments within two years, and just 3.97 million units globally this year.

As the traditional desktop PC declines, it’s great to see the rise of a new computing device that, unlike the slick consumer tablets du  jour, is intended to encourage hacking, tinkering and learning about hardware and software, rather than passive consumption of prepackaged apps — in the best tradition of the home computer. And a device which also, thanks to its tiny price-tag, has such huge disruptive potential.

So here’s hoping a lot more of the next million+ Pis end up very far from home indeed.

Raspberry Pi Microcomputers Are Powering A School Computing Lab In Rural Cameroon

Pi in Cameroon

The Raspberry Pi microcomputer has already put more than a million Pis in the hands of makers, tinkerers, parents and kids in its first year on sale. Which is an impressive feat for a device that’s designed to get more people dabbling in electronics and thinking about how software works. The Pi Foundation actually wanted to create a device that U.K. kids could cut their coding teeth on. But here’s a sign of how much more potential Pi has, above and beyond its original mission: Pis are being used to power a secondary school computing lab in rural Cameroon.

In a guest post on the Pi Foundation’s blog, a volunteer from a Belgian group that raised the funds to build and equip the school writes how they took 30 Pis out to Cameroon in their suitcase and used them to create a computing lab — along with screens, keyboards and mice bought locally. This Pi-powered computing class is itself powered by an on-site generator since the school is not connected to the public power network.

The school in question — Saint Marcellin Comprehensive College — is located in a small village called Binshua, close to Nkambe in the Northwest region of Cameroon. At present the Pis are being used for teaching the children how to use office productivity software but the aim is to get the kids coding too, in time:

All of the systems run on the Raspbian image from December, with LibreOffice and CUPS installed. The Pis are currently used to teach the children the basics of working with an Office suite. But we made sure that we gave the teacher a little introduction (and a good book) on programming in Scratch. So, now we are hoping that this will get Scratch introduced in the school curriculum as well.

The school’s lab doesn’t currently have an Internet connection but that’s something the Belgian group is working to change too.

The computers are all connected in a network. The central point of the network is a router that’s ready to be connected to a WAN modem. We hope to be able to provide a connection to the internet in the near future, which would certainly bring a small revolution into this rural area. Even without an internet connection, we believe that we created an advanced computer lab in this underdeveloped area. Giving the children in the area a chance to work their way to a better future. And that is our motivation.

It isn’t a stretch to say this small, low cost, low power microcomputer has the potential to provide a first computing experience for many more people in developing countries. The Pi hardware is cheaper than most mobile phones, let alone most smartphones — the other device touted as the likely first computing experience for the “next billions”. And it’s a lot cheaper than another Linux-based low cost computing project: the one laptop per child’s XO laptop (albeit, the price of the peripherals needs to be factored it).

In the following video, a teacher at the school is shown introducing the Pi to the class, and even though she mentions Microsoft’s Windows OS the reference is not likely to put smiles on many faces in Redmond:  ”This small box is not working with Windows operating system… It works with another type of operating system. It’s Linux. It’s also very popular — and it’s for free.”



Raspberry Pi sells out at $25 a pop (in the USA)

Less than a day after the least expensive iteration of the miniature stripped-down computer known as Raspberry Pi was formally introduced to the US market, it’s been sold out. This machine is only being offered (or was only being offered, rather) in the USA by the retailer known as Allied Electronics, and they’ve let it be known that they’ve currently sold out of the unit – but there’s a catch. According to TechCrunch, the retailer may have only had about 70 units to sell in the first place!

raspberry_pi-580x386

At the moment you’ll find that though there are no Raspberry Pi units left for sale in the $25 category, the slightly higher-powered $35 USD edition can still be picked up for its normal price. According to the Allied Electronics sales page for the $25 edition:

“Due to limited supply of the Raspberry Pi Model A, we are not offering preorders or backorders on the product at this time. The Raspberry Pi Model A will only be available for purchase when we have inventory on hand to fill the order. We regret this inconvenience and sincerely thank you for your patience.” – Allied Electronics

If you’ve been looking for this device over the past few weeks, you’ll know all to well that it’s been for sale in both Europe and Asia for some time, the most recent release happening here in the USA with about as much fervor surrounding it as any far more expensive PC. When you’ve got the ability to compute on a device that’s the size of a credit card that also costs less than a night on the town, units are bound to move!

You’ll be interested to know that the $35 Raspberry Pi remains available at many retailers throughout the USA. Stake your claim right this minute!

Have a peek at the timeline below to see more information on the Raspberry Pi miniature computer (and its many offshoots) and be sure to head to the Raspberry Pi tag portal for more sweet berry action through the future. Would you purchase one of these little firecrackers if you had the chance?

$25 Raspberry Pi Model Sold Out In US Debut

$25 Raspberry Pi Model Sold Out In US DebutThe $25 Raspberry Pi model is certainly selling like hot cakes, so much so that it sold out soon after debuting in the US. Yes sir, going on sale just yesterday, this $25 version of a tiny Linux computer is no longer available as all available stock has been snapped up by eager beavers. Of course, if you are hunting for the $25 Model A, you might want to settle for the slightly more expensive $35 Model B instead. After all, for a mere $10 more, you get more bang out of your hard earned buck, no?

Those who want to pick up the Model A will be treated to a message that reads, “this item is out of stock and may not be backordered. Please remove to continue.” As for Model B, it is available on sale although it has been backordered, with a waiting list that is up to 6 weeks long before your purchase arrives on your doorstep. Just to get an idea on what the $25 Model A offers, this “budget” edition comes with 256MB RAM and one USB 2.0 port, while the $35 Model B has double the RAM, a couple of USB 2.0 ports and an Ethernet port.
