The Raspberry Pi is a single-board computer developed in the UK by the Raspberry Pi Foundation. The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video.

Product Description

New Cased Kit includes Clear Raspberry Pi case plus the 512Mb Raspberry Pi Board
The design is based around a Broadcom BCM2835 SoC, which includes an ARM1176JZF-S 700 MHz processor, VideoCore IV GPU, and 512 Megabytes of RAM. This revision 2.0 board features two mounting holes for easy installation, a built-in reset circuit, and can be powered via the USB data ports. The design does not include a built-in hard disk or solid-state drive, instead relying on an SD card for booting and long-term storage. This board is intended to run Linux kernel based operating systems.
The Raspberry Pi use Linux-kernel based operating systems. Debian GNU/Linux, Iceweasel, Calligra Suite and Python are planned to be bundled with the Raspberry Pi. The Raspberry Pi does not come with a real-time clock, so an OS must use a network time server, or ask the user for time information at boot time to get access to time and date info for file time and date stamping. However a real time clock (such as the DS1307) with battery backup can be easily added via the I2C interface.

Building a Green Economy after the Great Leap Sideways - Environment - Utne Reader

Building a Green Economy after the Great Leap Sideways - Environment - Utne Reader

The Leap is first and foremost a cognitive jump, a shift in perspective and priorities. There is new technology and infrastructure involved—some of it fresh from the lab, some ancient in design—but it is not fundamentally about the tools. Whereas technological revolutions like the one that has reshaped telecommunications in the last twenty years are driven by new kinds of tools—“disruptive technologies,” in the preferred lingo of the digital world—The Leap is propelled by disruptive techniques. New kinds of policy, new metrics, new design parameters for vehicles and homes and whole cities, new ways of solving problems and thinking through challenges. It is not about material wealth or technical know-how but about creating the social and political will to commit to making the jump.
And finally—critically—The Leap is not just about escaping from but also moving toward, not motivated solely by the avoidance of disaster but also, even principally, by the desire to pursue our brightest possible future. The track on the other side leads not just somewhere safer but somewhere better.
The reason I can state this so baldly is because, as I said, I’ve been there. And what follows is, in one sense, a travel guide to the places where we arrive upon landing. I’ve seen first hand the exhilaration the Great Leap Sideways inspires, and I can see no good reason why anyone wouldn’t want to be where this Leap lands us. These are not allegorical scenarios like the train ride I described but real communities, cities, businesses, even whole nations—places that are already thriving in the sustainable twenty-first-century world order, all of them as real as Jeremiah Thompson’s New York and the yellowed pages of an 1818 shipping list. The Leap does not take us to a place of hardship or deprivation. It’s not about sacrifice, not a world predicated on going without or getting by. Quite the opposite: it’s a leap from a failing system to one that works, from decline and imminent peril to a new kind of prosperity with a healthy future stretching far out in front of it.

Graphene: The Next Big Thing in PV? - Solar Feeds

Graphene: The Next Big Thing in PV? - Solar Feeds:

The result is a device that uses a less expensive option than the indium tin oxide (ITO), which has been used as a transparent electrode for flexible PV cells. “Currently, ITO is the material of choice for transparent electrodes,” Gradečak said in a release about the research. The rarity of indium is main cost-driver in such applications.

In their abstract the researchers wrote that they were able to demonstrate growth of highly uniform and well-aligned zinc-oxide nanowire arrays on the graphene by modifying its surface with conductive polymer interlayers. “On the basis of this structure, we then demonstrate graphene cathode-based hybrid solar cells using two different photoactive materials,” they wrote. The cells used PbS quantum dots and the conjugated polymer P3HT. devices had AM 1.5G power conversion efficiencies of 4.2 percent and 0.5 percent, respectively. Such conversion efficiencies, while far below that of conventional silicon PV is close to the performance of ITO-based devices with similar architectures.

The resulting device has additional advantages beyond cost, including its light weight, flexibility, strength and chemical robustness, the institute said.

A chief challenge was dealing with graphene’s slipperiness, otherwise known as its stable and inert structure—without impacting its electricity conductive characteristics, Gradečak said. The polymer coatings modified its properties, allowing the researchers to bond the zinc oxide nanowires to it. The nanowires are layered over with a light reactive material aka, the aforementioned lead-sulfide quantum dots or polymer.

Thus far Gradečak and her team have only made proof-of-concept devices a half-inch in size. But given the processes used to make such devices, she anticipated a short road to making larger-sized devices. “I believe within a couple of years we could see [commercial] devices” based on this technology, she said.

Other researchers—including some at MIT are looking at other means of using graphene in a new generation of photovoltaic devices that could usher in a new generation of less expensive, flexible and more robust solar cells.

Tornado wind generator lands VC funding

PayPal co-founder Peter Thiel’s foundation recently invested $300,000 in a start-up company that aims to harness energy from tornadoes. A single twister-generator machine could produce as much energy as a coal-fired power plant without the downside of greenhouse gas emissions.
The Atmospheric Vortex Engine is the brainchild of Louis Michaud, a Canadian engineer who first started talking about the concept in the early 2000s. He’s successfully proven it works with 13-foot diameter version.
The investment money from Thiel “will allow us to carry out well documented development experiments in an academic environment,” Michaud told NBC News in an email. “Such results are required to get financial and power industry support to move to the next stage.”

Lessons learned about the A13 OLinuXino with A13-LCD7-TS | Skaag's Virtual Diary

Lessons learned about the A13 OLinuXino with A13-LCD7-TS | Skaag's Virtual Diary

I was initially trying to purchase a Raspberry Pi, but supplies being non-existent I was forced to look for alternatives, and I’m very glad I did because the end result is that I have a more powerful platform to work with. It’s faster, has 3 USB ports with tons of gpio pins, has an on-board nand chip, wifi adapter, sd card reader, audio in/out, and the pretty useful UEXT connector. It runs very cool, and since there are no moving parts or fans it is naturally silent.
In addition to this specific product being quite amazing, feature wise, Olimex has a very talented team of engineers who crank out new boards and designs at a pace rarely seen. They are already working on an A10 board, which packs even more impressive hardware and features. Once in a while they even find the time to write a new guide or how-to, and post it on their blog.
Apart from the Olimex engineers who are obviously dedicated to their cause, there’s a good number of individuals working on the “ARM Netbook” project. The Olimex and ARM engineers, as well as the community of users, all hang out on the Freenode IRC Network, on channels #olimex and #arm-netbook (If you have an IRC client you can click those links to directly join the rooms). I strongly urge you to join those chat rooms if you have questions, or if you feel you can help others with your skills and knowledge.
