New process for nanotube semiconductors could be graphene's ticket to primetime (video)
In many ways, graphene is one of technology's sickest jokes. The tantalizing promise of cheap to produce, efficient to run materials, that could turn the next page in gadget history has always remained frustratingly out of reach. Now, a new process for creating semiconductors grown on graphene could see the super material commercialized in the next five years. Developed at the Norwegian University of Science and Technology, the patented process "bombs" graphene with gallium, which forms droplets, and naturally arranges itself to match graphene's famous hexagonal pattern. Then, arsenic is added to the mix, which enters the droplets and crystallizes at the bottom, creating a stalk. After a few minutes of this process the droplets are raised by the desired height. The new process also does away with the need for a (relatively) thick substrate to grow the nanowire on, making it cheaper, more flexible and transparent. The inventors state that this could be used in flexible and efficient solar cells and light emitting diodes. We say forward the revolution.
Ergo Electronics outs trio of budget-friendly GoTab GTi slates in the UK
It would appear that a handful of tablet manufacturers want to take a piece of Apple's marketshare pie by tempting consumers with low-priced slabs. And, well, such is the case with small UK company Ergo Electronics. The Euro outfit recently introduced a trifecta of relatively economical GoTab GTi tablets; two of which come pre-loaded with Ice Cream Sandwich and one with Google's 4.1 treat. For starters, the top-of-the-line, Jelly Bean-loaded GTi97 boasts a 9.7-inch, IPS display alongside a dual-core, 1.6GHz RK3066 CPU and 1GB of RAM. Meanwhile, the GTi8 (8-inch) and GTi7 (7-inch) are both designed to be "super portable and lightweight," though the GTi8 packs a heavier punch thanks to a "high resolution" 160 ppi screen, same amount of RAM as its GTi97 cousin and a single-core, 1.2GHz CPU. Ergo Electronics is pricing these starting at £79 (around $128), with availability expected to be later this holiday season across the United Kingdom.
Researchers create 'rubber-band electronics' material, capable of stretching up to 200 percent (video)
One of the major issues with embedded medical devices is the lack of flexibility in existing electronics. Fortunately, researchers at the McCormick School of Engineering at Northwestern University have developed a new material that can create electronic components capable of stretching to 200 percent of their original size. One of the major obstacles was how stretchable electronics with solid metal parts suffered substantial drops in conductivity but this solution involves a pliable three-dimensional structure made from polymers with 'pores'. These are then filled with liquid metal which can adjust to substantial size and shape changes, all while maintaining strong conductivity. We've embedded a very brief video of the new stretchable material going up against existing solutions -- it's right after the break.
Club Jameco borrows from Etsy and Kickstarter, lets DIYers design, sell and buy project kits
Though electronics hobbyists may not have the same resources that the Maker Sheds of the world have to design, package and sell do-it-yourself kits, electronics component distributor Jameco plans to change that. With Club Jameco, enthusiasts can pitch their kit ideas to the electronic component wizards in Belmont, CA and if a project is deemed viable for production, they'll be provided with feedback and have their idea posted for public comment. After the creation of step-by-step kit instructions, a list of materials and undergoing final approval, kits will be sold to the adoring masses. Once projects roll off production lines and into garages, creators will be paid royalties anywhere from five to ten percent based on quarterly sales. Aside from giving DIYers another sales avenue, it's also an opportunity for those who've been wary of piecing together projects to finally dive in sans the added fuss. Hankering to propose a bundle of your own? Per usual, all the particulars can be found in the source link below.
New material brings semiconducting to the graphene party
Scientists at the University of Wisconsin-Milwaukee have cooked up a new graphene-based material that could provide a speed boost for all electronics. We've seen the carbon allotrope turn up in circuitry and transistors before, but the new chemical modification -- graphene monoxide -- is said to be easier to scale up, and most importantly is semiconducting, unlike the insulating or conducting forms that have preceded it. This also means graphene can now provide the triad of electrical conductivity characteristics. The scientists were honest enough to admit the discovery was as much by chance as design, with it coming to light while investigating another material containing carbon nanotubes and tin oxide. We're sure they're not the first to make a discovery this way, we just haven't had time to check the notes to be sure of it.
Best Buy details its 50 big box store shutdowns in the US, most will close by May 12th
We knew Best Buy planned to close 50 of its big box retail locations by the end of its 2013 fiscal year, and now (just days after Mike Mikan took the CEO-reigns from Brian Dunn) it's detailed all of the stores that'll be getting the boot. As it stands, two locations have already been shut down, with six others set to close before the year is out -- and the company hopes to clear out the remaining 42 before May 12th. Employees at most of the stores were informed of the news this weekend, and despite the impending closures, the company says it'll try to re-position them within the company or offer up severance packages. Past that, Best Buy is also reaching out to the customers of these stores, noting that they'll still have other nearby locations to choose from -- try-before-you-buy online shoppers rejoice. There's still no specific word about the 100 Best Buy Mobile stores it hopes to setup, but more information will be forthcoming later in the year. Hit up the press release after the break if you'd like to parse the full list of affected locations or find out more details about the planned closures.
Best Buy to close 50 big box US retail stores, open 100 Mobile stand-alone outlets in 2013
Still driving to your local Best Buy to fondle all the latest gadgets before swiping your card, or hopping to the web to pull the trigger? That tradition could be short-lived, if you happen to live near one of 50 big box retail stores that the company plans to shutter in 2013. The move was announced alongside Best Buy's Q4 earnings report, which includes action items aimed to trim $800 million in costs by 2015. The closings will no-doubt come along with staffer reductions, some of whom could be transferred to one of 100 Best Buy Mobile "small format stand-alone stores" set to launch next year. While an unfortunate move for some customers and employees, it does show some foresight on behalf of BBY management, who likely recognize a continuing shift to online purchasing, and a greater emphasis on mobile devices, which require significantly smaller showrooms, cost less to ship and could offer greater margins to boot.
F.A.A. might review policy on iPads and other gadgets during takeoff, landing
Whenever I travel by air, I always make sure that I have a clean, untouched crossword puzzle in the in-flight magazine before takeoff. Why? Because of the idiotic regulation from the Federal Aviation Administration (F.A.A.) that says that I can't use portable electronic devices during takeoff and landing. According to a post on the New York Times site this morning, the F.A.A. may be taking a "fresh look" at use of electronics in the passenger cabin during the critical phases of flight. Blogger Nick Bilton called the F.A.A. last week and spoke with deputy assistant director for public affairs Laura J. Brown, who said the administration has decided it's high time that they take a look at the effects -- if any -- caused by use of electronic devices on aircraft. The last time any testing was done was 2006, back when the iPad and most e-readers were simply mockups in labs. Apparently, airlines have always had the option to approve electronic devices for use once they have tested each model of each device on a separate flight with no passengers. Due to the complexity and time involved, no airline has done so. Can you imagine each airline spending valuable fuel and crew time to test 16, 32, and 64 GB versions of the iPad, iPad with 3G, iPad 2 Wi-Fi, iPad 2 (GSM), iPad 2 (CDMA) and so on,? The current testing also says that the airline would have to perform these tests on each and every aircraft type in its fleet. With these test restrictions, airlines have wisely just banned usage. The F.A.A. isn't saying how they want to change the testing process to make it easier, just that they want to bring together "electronics manufacturers, consumer electronic associations, aircraft and avionics manufacturers, airlines, pilots, flight attendants and passengers" to take a fresh look at the regulations. Bilton came up with a great idea: have major airlines volunteer one aircraft for a limited time for testing, and have electronics manufacturers pay for the testing -- if you don't contribute to the testing, your devices don't get on the list. That way, the cash-strapped F.A.A. doesn't foot the bill for testing the devices. Don't expect to see any changes in the near future, however. We are talking about a government agency, after all. Oh, and by the way -- these regulations do not pertain to mobile phones, so don't expect to be able to chat with your BFF during takeoff. [via MacRumors]
CircuitLab brings schematic design and sharing to the browser (video)
The designs for all those wonderful Arduino and electronics projects don't create themselves, sadly. No, a person needs to put in time and effort laying out the circuits and carefully arranging the components, often by hand, but sometimes with aid of a software tool. A new player in that field is CircuitLab, a surprisingly full featured app for sketching out schematics and simulating them that lives entirely in the browser. It's also amazingly user friendly and simple for even the novice hobbyist to dive into. Finally, once you've finished with your project you can make the design public and share it with others. Check out the quick intro video after the break and sign up at the source.
NHTSA issues 'distraction guidelines' proposal for in-vehicle electronics, MyFord Touch frets
With companies like Tesla and Ford replacing tactile, in-dash systems with touchscreens and gizmos, the National Highway and Transportation Safety Administration wants to set "distraction guidelines" for how automakers implement factory-installed in-car electronics. Nearly a year after discussing the possibility of bringing restrictions to in-car information, US Transportation Secretary Ray LaHood unveiled phase one of a (potential) three-part, "first-ever federal proposal" loaded with suggestions for keeping driver's eyes and attention on the road. Notably, these voluntary guidelines take aim at "communications, entertainment, information gathering and navigation devices or functions that are not required to safely operate the vehicle." According to Reuters, though, the Alliance of Auto Manufacturers claims that "elements" of the guidelines have been in practice for nearly ten years. The ideas range from ensuring that one hand is always left free for steering and restricting the entry of text, such as an address, unless the your car is in park, to limiting in-dash text prompts to "no more than 30 characters of text unrelated to the driving task" so that your eyes can't wander off of the road for too long. Passengers, of course, would be free to do whatever they wish. Vehicles under 10,000 pounds are said to be the primary focus, with the NHTSA noting that electronic warning systems will not be on the radar as they intend to help drivers, well, drive. Before the proposal spins into action, beginning in March it will be up for public comment for 60 days L.A., Washington D.C. and Chicago. Depending on how the phase one guidelines pan out, phase two will focus on devices brought into vehicles, like cellphones, while phase three would set its sights on voice controls. If you're curious about all of the specifics, you'll find more info in the press release after the break and the full proposal draft at the source link below.
Adafruit's Circuit Playground app deciphers resistor codes, helps you remember Ohm's Law
If the names Phillip Torrone, Limor Fried and Collin Cunningham don't ring a bell then you probably need to hand over your geek badge. If, on the other hand, those names immediately make you sit up and pay attention, you maybe excited to hear the trio have just released the first Adafruit-branded app for iOS. Circuit Playground is a reference app for makers, hackers and tinkerers that helps you decipher resistor and capacitor values; calculate resistance, current or voltage; convert decimal, hexadecimal and binary values; and store PDF data sheets for ICs. The app is $2.99, but it comes with a $3 credit at the Adafruit shop, so it's kinda-sorta free. It's available for iPad and iPhone only, but an Android version is in the works. If you're an impatient Google fan, they suggest you check out ElectroDroid which performs many of the same functions and we can confirm is awesome. Check out the video after the break and hit up the source link to get Circuit Playground now.
Insert Coin: BoardX is an open-source, modular motherboard for prolific prototypers
In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. We're more than a little enamored with Arduino and its DIY microcontroller ilk. But we'll admit, there are a few limitations that the compulsive prototyper might find bothersome. Chief amongst them is the lack of modularity, Now, sure, you can easily add all sorts of sensors, ports and radios to your Uno (or Duemilanove if you're old school) but that generally requires piling shield, upon shield, upon shield, until you've got a stack of boards three-feet high. And, if you want to use an ARM chip instead of an AVR for a project? Well that's a whole other set of boards. Kevin Greene has decided to address these perceived "weaknesses" with BoardX -- a modular, open-source prototyping platform.
Ben Heck cooks up proximity sensor for cyclists, still no substitute for keeping eyes open
Ben Heck's been busy -- again. In the latest episode of his bi-weekly show he puts his considerable brain power to work on cycle safety. He uses Parallax ping sensors connected to an Arduino to measure whether you're in any danger from nearby obstacles and traffic. The red and green LED indicators are hooked up to ambient light sensors so they don't blind you while riding at night -- looks like Mr. Heck's thought of everything. This week's episode also includes more secrets behind the prolific modder's Android APK-based baby seat. Check out both projects after the break.
Foxconn posts $943 million net profit for first half of 2011, 20 million iPad 2s coming for Q3?
It looks like 2011 is shaping up to be a solid year for Foxconn. Earlier this week, the hardware manufacturer announced net profits of NT$27.38 billion (about $943.72 million) for the first half of this year, just a few months after posting a disappointing $218 million loss for all of 2010. These figures, however, are down about 21 percent from the first six months of last year, when Foxconn (AKA Hon Hai Precision) reported net profits of NT$34.74 billion (around $1.2 billion). In a statement, Hon Hai said its first semester results were "as expected and remain seasonal," considering today's harsh and uncertain financial climate. DigiTimes, meanwhile, is reporting that the electronics maker is "expected" to ship a full 20 million new iPad 2s during the third quarter of this year, though the Taiwan-based news outlet didn't offer much in the way of explanation or sourcing.
Apple puts PCs on free recycling party list, opens doors to iPads, iPhones
After being forced to pay off the door man to get into Apple's electronics recycling party for years now, PCs are finally getting in for free -- VIP style. Apple has revised its Reuse and Recycling Program and opened the gates to sheep from another shepherd's flock. The new rules are quite a departure from past protocol, which charged PC users 30 bones to recycle non-Apple computers and displays -- unless of course they agreed to purchase a Mac, in which case Apple would kindly do it for free. As part of the restructured program, ripe old iPads and iPhones are now eligible for Apple's exchange program as well, where you'll get a gift card if your device is actually worth anything. The company still recycles old iPods and mobile phones (regardless of manufacturer) for free, and offers 10% off a new iPod if you hand over an old one. With the revised plan it's safe to say the folks at Apple ditched the program's old theme song, "It's Not Easy Being Green," and are instead spinning a new track. Sparkly silver jacket not included.

Enter CircuitBee, a document sharing site dedicated to one thing, and one thing only -- schematics. It's kind of like Scribd but, instead of being loaded with court documents and shoddy how-to books, it features user-uploaded circuit diagrams to get you started on your next soldering and etching project. The selection at the site is rather sparse at the moment, but since it's only in alpha we'll cut it some slack. Check out the site at the source link, and don't be surprised if a few submissions from your favorite Engadget writers start popping up.
Increase in iPad recycling prompts Gazelle to enter reseller market
After the iPad 2 announcement, Gazelle saw a marked increase in the number of first generation iPads being recycled by consumers. The electronics recycler has received so many iPad 1 tablets in good to excellent condition that it has decided to begin selling them back to consumers in the upcoming weeks. Gazelle lets consumers send in used electronics for cash. It's an easy way to sell your device without the hassle of deadbeat sellers on eBay or the spam from Craigslist. The amount paid out depends on the model of the device and its condition. Currently, Gazelle is paying $183 for a good condition 16 GB WiFi iPad model. Since the iPad 2 announcement, the company has accepted almost 17,000 iPads, 90% of which are in mint condition. Rather than resell these iPads through Amazon or eBay, Gazelle has decided to open an online store as an extension of its current website. Pricing is still being determined, but the used iPads will likely cost between US$300 to $500. Gazelle may also collaborate with Square Trade to offer warranties on these used devices. If all goes well with the iPad, Gazelle plans to eventually add the iPhone to its online store. The company expects to receive over 50,000 iPhone 4 handsets when the iPhone 5 hits the market later this year.
Sony offers sneak peek of new LA store - no fooling (video)
You might see a bunch of fake news on the internet tomorrow, but considering what we've seen of Sony's new LA storefront, we're fairly certain this isn't a prank. That's right, Sony's launching a newly branded retail store in the City of Angels Friday, and from the look of things, it spared no expense. The 4,200-square foot space is the first to ditch the Sony Style moniker for the simpler Sony Store, and while the aesthetics are decidedly minimal, the experience is anything but. As you might expect, the shop offers demos of a slew of devices; it's packed full of everything from VAIOs to ray modelers to 3D Handycams, and it's also rocking a fully loaded home theater setup called "The Cube." Considering the outfit's been looking to up its retail cred, we'd say the new spot has the stuff to do the job, even if that bright white modular look does seem strangely familiar. If you're in the LA area, you can check out the new digs starting tomorrow -- if not, hit up the guided video tour above.
Researchers aim to replace copper with aluminum as a conductor in auto power systems
As every lonely cat lady with a police scanner knows, the price of copper is as high as it's ever been -- and there is no reason this trend won't continue. Of course, this affects more than those creeps that sneak into basements to steal the plumbing: the aforementioned ductile metal is currently the best conductor for on-board power systems in automobiles. But with any luck this might soon change. In order to replace copper with aluminum in power supply systems, several challenges need to be addressed, including the fact that aluminum creeps as temperatures increase, and the corrosive effect of bringing the two materials together. Among the efforts of Technische Universitat Munchen (TUM) and BMW to bring aluminum into EVs, the LEIKO power plug uses a sheet metal cage and a pressure spring to allow copper and aluminum elements to remain in contact. If all goes according to plan, TUM's Professor Udo Lindemann (not to be confused with Udo Dirkschneider, the diminutive frontman of German heavy metal bands Accept and U.D.O.) predicts that "the high-voltage on-board systems of most electric vehicles to be based on aluminum by 2020." Check out an awesome picture of Dirkschneider after the break.
