Raspberry Pi's $25 Model A Hits Production Line 105

Posted by timothy
from the house-automation-brain-perhaps dept.
hypnosec writes "The Raspberry Pi Foundation has announced that the cheaper variant of the Raspberry Pi — the Model A — has entered production phase. Model A of the credit-card sized computer has been stripped of its Ethernet port and a USB port, leaving just one USB port. This model comes with 256MB RAM, but as it is less complex compared to its predecessor it will consume less power, thus opening up quite a few new usage scenarios. The Foundation has posted the first image of the $25 Model A on its site and noted 'We're anticipating that those of you who buy the Model A will be using it for different applications from Model B owners.'"

sfcrazy writes "Ouya has stuck to its deadlines. The team has posted an update on the official blog that the units will start shipping on the scheduled date of December 28th. These units are for those developers who backed the project on Kickstarter. There is some surprise for developers with this console. 'What we didn't tell you was that the advance dev consoles you ordered are pretty special – you'll know what I mean when you open yours. They're rare drops. :P,' says the official post."

DOE Wants 5X Improvement In Batteries In 5 Years 305

Posted by Soulskill
from the charging-scientists-with-this-task dept.
dcblogs writes "The U.S. Dept. of Energy has set a goal to develop battery and energy storage technologies that are five times more powerful and five times cheaper within five years. DOE is creating a new center at Argonne National Laboratory, at a cost of $120 million over five years, that's intended to reproduce development environments that were successfully used by Bell Laboratories and World War II's Manhattan Project. 'When you had to deliver the goods very, very quickly, you needed to put the best scientists next to the best engineers across disciplines to get very focused,' said U.S. Energy Secretary Stephen Chu, on Friday. The Joint Center for Energy Storage Research isn't designed to seek incremental improvements in existing technologies. This technology hub, according to DOE's solicitation (PDF), 'should foster new energy storage designs that begin with a "clean sheet of paper" — overcoming current manufacturing limitations through innovation to reduce complexity and cost.' Other research labs, universities and private companies are participating in the effort."

3D Printing of Custom Personal Electronics Arrives 72

Posted by Soulskill
from the print-all-the-things dept.
Zothecula writes "Researchers at the University of Warwick have created a cheap plastic composite that can be used even with low-end 3D printers, to produce custom-made electronic devices. The material, nicknamed 'carbomorph,' is both conductive and piezoresistive, meaning that both electronic tracks and touch-sensitive areas can now be easily embedded in 3D-printed objects without the need for complex procedures or expensive materials."

Ask Slashdot: Good Linux Desktop Environment For Hi-Def/Retina Displays? 234

Posted by Soulskill
from the time-to-start-thinking-about-this-again dept.
Volanin writes "I have been using Linux for the last 15 years both at home and at work (mostly GNOME and now Unity). Recently, I gave in to temptation and bought myself a Macbook retina 15". As you can read around, Linux still has no good support for this hardware, so I am running it inside a virtual machine. Running in scaled 1440x900 makes the Linux fonts look absolutely terrible, and running in true 2880x1800 makes them beautiful, but every UI element becomes so tiny, it's unworkable. Is there a desktop environment that handles resolution independence better? Linux has had support for SVG for a long time, but GNOME/Unity seems adamant in defining small icon sizes and UI elements without the possibility to resize them."

Flexible Phones 'Out By 2013' 152

Posted by Soulskill
from the now-if-they-can-only-make-phones-into-snap-bracelets dept.
dryriver sends this quote from a BBC report: "Imagine treating your phone like a piece of paper. Roll it up. Drop it. Squish it in your backpack. Step on it — without any damage. Researchers are working on just such handsets — razor-thin, paper-like and bendable. There have already been prototypes, attracting crowds at gadget shows. But rumors abound that next year will see the launch of the first bendy phone. Numerous companies are working on the technology — LG, Philips, Sharp, Sony and Nokia among them — although reports suggest that South Korean phone manufacturer Samsung will be the first to deliver. Samsung favors smartphones with so-called flexible OLED (Organic Light Emitting Diode) technology, and is confident that they will be 'very popular among consumers worldwide.' Their screens will be 'foldable, rollable, wearable and more, [and] will allow for a high degree of durability through their use of a plastic substrate that is thinner, lighter and more flexible than conventional LCD technology,' says a Samsung spokesperson.'"

Ask Slashdot: DIY 4G Antenna Design For the Holidays? 135

Posted by samzenpus
from the tune-in dept.
eldavojohn writes "This holiday season I will return to the land of my childhood. It is flat and desolate with the nearest major city being a three hour car drive away. Although being able to hear the blood pulse through your ears and enjoying the full milky way is nice, I have finally convinced my parents to get "the internet." It's basically a Verizon Jetpack that receives 4G connected to a router. My mom says it works great but she has complained of it cutting in and out. I know where the tower is, this land is so flat and so devoid of light pollution that the tower and all windmills are supernovas on the horizon at night. Usually I use my rooted Galaxy Nexus to read Slashdot, reply to work e-mails, etc. I would like to build an antenna for her 4G device so they can finally enjoy information the way I have. I have access to tons of scrap copper, wood, steel, etc and could probably hit a scrap yard if something else were needed. As a kid, I would build various quad antennas in an attempt to get better radio and TV reception (is the new digital television antenna design any different?) but I have no experience with building 4G antennas. I assume the sizes and lengths would be much different? After shopping around any 4G antenna costs way too much money. So, Slashdot, do you have any resources, suggestions, books, ideas or otherwise about building something to connect to a Jetpack antenna port? I've got a Masters of Science but it's in Computer Science so if you do explain complicated circuits it helps to explain it like I'm five. I've used baluns before in antenna design but after pulling up unidirectional and reflector antenna designs, I realize I might be in a little over my head. Is there an industry standard book on building antennas for any spectrum?"

New Small Fission Reactor For Deep-space Missions Demonstrated 122

Posted by samzenpus
from the in-space-nobody-can-hear-you-split-an-atom dept.
cylonlover writes "Exploring the regions of deep space beyond Mars means sending probes where solar power isn't practical. Since the 1960s, NASA has equipped its Apollo missions and unmanned explorers with Radioisotope Thermal Generators (RTGs). These have worked very well, but they run on plutonium 238, which is currently in short supply. Therefore, the Los Alamos National Laboratory is developing a new small nuclear reactor for spacecraft that uses uranium instead of plutonium to power Stirling engines and generate electricity. At the Nevada National Security Site's Device Assembly Facility near Las Vegas, engineers from Los Alamos, the NASA Glenn Research Center and National Security Technologies LLC conducted a Demonstration Using Flattop Fissions (DUFF) experiment that produced 24 watts of electricity using a pair of free-piston Stirling engines."

from the get-that-theme-song-out-of-my-head dept.
Readycharged writes "A generation's childhood dreams have come true with the creation of a working 'robot in disguise' Transformer which, when operated by remote control, morphs from a luxury sports car to a missile hurling robot in seconds. Japanese inventor Kenji Ishida is planning to make 10 lucky (and undoubtedly rich) purchasers owners of these toys in the run up to Christmas, having first displayed them at the Maker Faire in Tokyo during the first week of December. For those willing to wait a few years, Ishida plans to have created a life size, drivable model by 2030."

Notch Expands On 0x10c, Microsoft and Quantum Computing 94

Posted by timothy
from the and-for-his-next-trick dept.
eldavojohn writes "Mojang's Marcus Persson (better known as 'Notch') has answered quite a few questions in an interview with PC Gamer about his new game 0x10c. Since its announcement, there's been very few details about game play aside from the DCPU-16 and art tests. But in this interview, Notch has revealed quite a bit about how the game will function and non-final ideas he has for either a monthly fee to play in a 'multiverse' or micropayments. He talks about a custom OS people are working on to load into the game's CPU as well as a an in-game 3D printer that will allow you to make virtual objects. When asked about Kickstarter and his Oculus dev kit, Notch said 'Definitely going to make it work in 0x10c no matter what' and his account of using the Oculus Rift sounds more than promising for the VR Device. When asked about Linux he said, '[Linux] is wonderful. I think we need to have it, and it's a shame that more people, including myself, don't use it. It's gotten easier and friendlier.' When asked about Microsoft he said, 'I use their OS – Windows 7 is an amazing operating system in my opinion and of course there's the Xbox, which I love. I'm sure Bing is going to take off and save them. [Editor's note: Notch is smiling mischievously as he says this.]'"

The Coming Wave of In-Dash Auto System Obsolescence 445

Posted by timothy
from the new-din-standard-called-for dept.
jfruh writes "Automakers are striving mightily to bring their in-dash systems into the modern age, providing integration with smartphones and other advanced features. The problem: while smartphones go in and out of vogue every few years, modern cars have lifespans of a decade or more. Add in the fact that many (though not all) manufacturers have no plans to allow software upgrades to their systems, and you might end up driving a car with a fancy in-dash computer system that's completely useless for much of the time you own it."

The Secret To Iranian Drone Technology? Just Add Photoshop 183

Posted by timothy
from the innocent-whistling-of-tail-fins dept.
garymortimer writes "Earlier this month, Iran's news agency provided visual evidence that its government had figured out to make a fancy new drone that could take off and land vertically. What they didn't tell us is that they used Photoshop to make it stop taking off from the roof of Japan's Chiba University, which built the aircraft and never had anything to do with Iran's alleged version of it."

Ask Slashdot: Server Room Toolbox? 416

Posted by samzenpus
from the get-your-tools dept.
jandersen writes "I am the system manager in charge of a smallish server room (~50 servers, most in racks), and I am going to buy a set of tools; but first I want to hear what other people think would be a good idea. Certainly a range of good quality screwdrivers — slotted, Phillips, Pozidriv, Torx. But what else? Tape measure? Spirit level (for aligning the racks)? Any meters or cable testers? A wood lathe? I can probably get away with a budget of a few hundred GBP, but there ought to be some mileage in that."

Research Discovery Could Revolutionize Semiconductor Manufacturing 64

Posted by Soulskill
from the nobody-thought-to-use-playdoh-before-this dept.
New submitter arobatino writes "A new method of manufacturing semiconductors which eliminates the substrate (in other words, no wafer) could be much faster and cheaper. From the article: 'Instead of starting from a silicon wafer or other substrate, as is usual today, researchers have made it possible for the structures to grow from freely suspended nanoparticles of gold in a flowing gas. "The basic idea was to let nanoparticles of gold serve as a substrate from which the semiconductors grow. This means that the accepted concepts really were turned upside down!" Since then, the technology has been refined, patents have been obtained and further studies have been conducted. In the article in Nature, the researchers show how the growth can be controlled using temperature, time and the size of the gold nanoparticles.'"
