cartechboy writes "Does the Tesla Model S suck down power even when the car is switched off? Recently, a tweet to Elon Musk with an article saying so sparked the Tesla CEO's attention. He tweeted that it wasn't right and that he'd look into the situation. Then a few hours later, he tweeted that the issue had to do with a bad 12-volt battery. Turns out Tesla had already called the owner of the affected car and sent a service tech to his house to replace that battery — and also install a newer build of the car's software. Now it appears the 'Vampire Draw' has been slain. The car went from using 4.5 kWh per day while turned off to a mere 1.1 kWh. So, it seems to be solved, but Tesla may either need to fix some software, or start sending a few new 12-volt batteries out to the folks still experiencing the issue."

Kristian vonBengtson writes "Wanna build your own space capsule capable of doing an atmospheric re-entry on a suborbital mission? Well, here are some production hints and a visual guide." The initial stages begin with sketches on paper before moving to 3D design software. He writes, "A whole bunch of sketches were done to get some kind of initial idea of the size, subsystems layout and how to actually produce the capsule while keeping an open structure for further development and potential changes. One of the main concerns was the small size and the ability to easy install and replace avionics. This led to the decision that all external side panels will have to accommodate being taken on and off – no welding, only on the main structure." Afterward, he moves on to show the final metal cuts and how the pieces are put together via bolts and welding.

itwbennett writes "Broadcom Chairman and CTO Henry Samueli has some bad news for you: Moore's Law isn't making chips cheaper anymore because it now requires complicated manufacturing techniques that are so expensive they cancel out the cost savings. Instead of getting more speed, less power consumption and lower cost with each generation, chip makers now have to choose two out of three, Samueli said. He pointed to new techniques such as High-K Metal Gate and FinFET, which have been used in recent years to achieve new so-called process nodes. The most advanced process node on the market, defined by the size of the features on a chip, is due to reach 14 nanometers next year. At levels like that, chip makers need more than traditional manufacturing techniques to achieve the high density, Samueli said. The more dense chips get, the more expensive it will be to make them, he said."

Arvydas Juskevicius (say that five times fast) is an independent software developer and hardware hacker based in London (which is where I got a chance to talk with him) who's decided to bring the useful LED signalling capabilities of many modern smartphones into the world of desktop or laptop computers. With his £10 BlinkStick kit (£15 pre-assembled), you get a programmable multi-color LED that's about the size of a flash memory key. Deceptively simple -- it's essentially one giant pixel, after all, which might not sound exciting when you have millions of them on a dense display surface. But that LED light is something you can use as a signal for alarms, or to tell you that you have a message from one app while another is at full-screen, or practically anything else that you can devise software to notice and react to. I get the sense that Juskevicius would prefer that people get the kit version, to help spur interest in actually soldering some hardware rather than just plugging it in. If you're allergic to paying in other than U.S. dollars, the BlinkStick is also available from Adafruit Industries. Watch the video below to see it in action.

curtwoodward writes "For some reason, we're still plugging in electric-powered devices like a bunch of savages. But technology developed at MIT could soon make that a thing of the past, at least for hybrid cars. A small Boston-area company, WiTricity, is a key part of Toyota's growing experiment with wireless charging tech---something the world's largest car maker says it will start seriously testing in the U.S., Japan and Europe next year. The system works by converting AC to a higher frequency and voltage and sending it to a receiver that resonates at the same frequency, making it possible to transfer the power safely via magnetic field. Intel and Foxconn are also investors, and you might see them license the tech soon as well."

doom writes "Ian Sample at the Guardian UK does a really thorough write-up of what's going on with the Fukushima Clean-up. From the article: 'Though delicate and painstaking, retrieving the fuel rod assemblies from the pools is not the toughest job the workers face. More challenging by far will be digging out the molten cores in the reactors themselves. Some of the fuel burned through its primary containment and is now mixed with cladding, steel and concrete. The mixture will have to be broken up, sealed in steel containers and moved to a nuclear waste storage site. That work will not start until some time after 2020.'"

sl4shd0rk writes "It seems you can be arrested in Georgia for drawing 5 cents of electricity from a school's outdoor receptacle. Kaveh Kamooneh was charged with theft for plugging his Nissan Leaf into a Chamblee Middle School 110V outlet; the same outlet one could use to charge a laptop or cellphone. The Leaf draws 1KW/hour while charging which works out to under $0.10 of electricity per hour. Mr Kamooneh charged his Leaf for less than 30 minutes, which works out to about a nickel. Sgt. Ernesto Ford, the arresting officer, pointed out, 'theft is a theft,' which was his argument for arresting Mr. Kamooneh. Considering the cost of the infraction, it does not seem a reasonable decision when considering how much this will cost the state in legal funds. Does this mean anyone charging a laptop or cell phone will be charged with theft as well?"

nk497 writes "Consumer hard drives don't fail any more often than enterprise-grade hardware — despite the price difference. That's according to online storage firm Backblaze, which uses a mix of both types of drive. It studied its own hardware, finding consumer hard-drives had a failure rate of 4.2%, while enterprise-grade drives failed at a rate of 4.6%. CEO Gleb Budman noted: 'It turns out that the consumer drive failure rate does go up after three years, but all three of the first three years are pretty good,' he notes. 'We have no data on enterprise drives older than two years, so we don't know if they will also have an increase in failure rate. It could be that the vaunted reliability of enterprise drives kicks in after two years, but because we haven't seen any of that reliability in the first two years, I'm skeptical.'"

sfcrazy writes "The creator of the most sought after 'Android' of the world has been secretly working on creating a robotics division within Google. The search engine giant has acquired over seven robotics companies recently to create the robotics unit which is being headed by none other than Andy Rubin himself. Andy made the disclosure in an interview given to the New York Times." Their initial goal is to automate the woefully manual process of electronics manufacturing.

OldJuke writes "Called the YotaPhone, the device pairs a traditional LCD color touch-screen on one side with a black-and-white, electronic-paper display on the other, allowing users to continuously view data in real time without having to constantly wake up their phones and drain their batteries. General interaction will be done through the LCD screen, but the e-paper display allows an image to be displayed at all times — from maps, airline boarding passes and family photos to Twitter messages and emails — but only uses power when the picture changes. BBC News interviewed the company's leader, Vlad Martynov, for a hands-on demonstration."

theodp writes "'The desktop or laptop is now in decline,' writes John Sall, 'squeezed from one side by mobile platforms and from the other side by the cloud. As a developer of desktop software [by choice not necessity], I believe it is time to address the challenges to our viability. Is software for the desktop PC now the living dead, or zombieware.' While conceding there's some truth to truisms about the death of the desktop, Sall believes there's still life in the old desktop dog, 'We live in a world of computing where dreams come true,' Sall concludes. 'The mainframe bows to the minicomputer. The minicomputer bows to the personal computer. The personal computer bows to the tablet and smart phone. It seems as if these will soon bow to the smart watch or smart glasses. But at each step along the way, some applications find their best home – and other applications as well as new applications find the more convenient and smaller home better...So let's keep our desktops and laptops, our PCs and Macs. They are amazingly good at what they do.'"

MojoKid writes "There's a great deal riding on the launch of AMD's next-generation Kaveri APU. The new chip will be the first processor from AMD to incorporate significant architectural changes to the Bulldozer core AMD launched two years ago and the first chip to use a graphics core derived from AMD's GCN (Graphics Core Next) architecture. A strong Kaveri launch could give AMD back some momentum in the enthusiast business. Details are emerging that point to a Kaveri APU that's coming in hot — possibly a little hotter than some of us anticipated. Kaveri's Steamroller CPU core separates some of the core functions that Bulldozer unified and should substantially improve the chip's front-end execution. Unlike Piledriver, which could only decode four instructions per module per cycle (and topped out at eight instructions for a quad-core APU), Steamroller can decode four instructions per core or 16 instructions per quad-core module. The A10-7850K will offer a 512-core GPU while the A10-7700K will be a 384-core part. Again, GPU clock speeds have come down, from 844MHz on the A10-6800K to 720MHz on the new A10-7850K but should be offset by the gains from moving to AMD's GCN architecture."

symbolset writes "Zach Whittaker over at ZDNet covers an IDC report. In it the 2013 9.7% forecast decline in PC shipments is advanced to 10.1%. Further, IDC's longer-term forecast turns quite grim: contracting 23% from 2012 levels by 2017. There is also a projection of future Windows tablet sales, and a statement that total Windows tablet sales for 2013 are expected to be 'less than 7.5 million units.'"

First time accepted submitter wick3t writes "The Neo900 fundraising campaign has already achieved the milestone of 200 pre-orders which means that mass production is now feasible. This follows a successful first prototype that was showcased at the OpenPhoenux-Hard-Software-Workshop 2013. Their next target is 1000 pre-orders as they aspire to reduce the production costs of each device." For those not familiar, the Neo 900 is an offshoot of the OpenMoko GTA04 designed for use in the popular Nokia N900 case (and, yes, they're fixing the weak usb port).

ckwu writes "As a way to generate renewable electricity, researchers have designed methods that harvest the energy released when fresh and saline water mix, such as when a river meets the sea. One such method is called pressure-retarded osmosis, where two streams of water, one saline and one fresh, meet in a cell divided by a semipermeable membrane. Osmosis drives the freshwater across the membrane to the saltier side, increasing the pressure in the saline solution. The system keeps this salty water pressurized and then releases the pressure to spin a turbine to generate electricity. Now a team at Yale University has created a prototype device that increases the power output of pressure-retarded osmosis by an order of magnitude. At a full-scale facility, the estimated cost of the electricity generated by such a system could be 20 to 30 cents per kWh, approaching the cost of other conventional renewable energy technologies."

Zothecula writes "Last August, it looked as if NASA's Kepler space telescope was as good as scrap due to the failure of its attitude control system. Now the space agency proposes what it calls the K2 mission concept, which may fix the problem by using the Sun to regain attitude control and allow Kepler to resume its search for extrasolar planets."
