Building a Telegraph Using Only Stone Age Materials 238

MMBK writes "It's the ultimate salvagepunk experiment, building a telegraph out of things found in the woods. From the article: 'During the summer of 2009, artist Jamie O’Shea of the organization Substitute Materials set out to test whether or not electronic communication could have been built at any time in history with the proper knowledge, and with only tools and materials found in the wilderness of New Jersey.'"

Batteries Smaller Than a Grain of Salt 68

An anonymous reader writes "Lithium-ion batteries have become ubiquitous in today's consumer electronics — powering our laptops, phones, and iPods. Research funded by DARPA is pushing the limits of this technology and trying to create some of the tiniest batteries on Earth, the largest of which would be no bigger than a grain of sand. These tiny energy storage devices could one day be used to power the electronics and mechanical components of tiny micro- to nano-scale devices."

Black Silicon Used For Surveillance? 56

An anonymous reader writes "For the past decade, 'black silicon' has been touted as a way to make super-sensitive image sensors and ultra-efficient solar cells. That's because the material — silicon wafers treated with sulfur gases and femtosecond laser pulses — is much better at absorbing photons and releasing electrons than conventional silicon, at least over certain wavelengths. In 2008, Harvard spinoff SiOnyx went public with its plans to commercialize black silicon. But what happened to those plans? Today SiOnyx revealed in another exclusive that it has raised new venture financing from Microsoft co-founder Paul Allen and other big investors. It also has formed a key strategic partnership to scale up manufacturing of black silicon — and go after markets in security, surveillance, automotive, consumer devices, and medical imaging."

A 3D Lego Fabricator Made of Lego 87

eldavojohn writes "Making a Lego printer is pretty cool if you've never seen The LegoMakerBot. The creator has instructions on his site on how to make (out of Lego bricks) a machine that 'prints' Lego models — much like a 3D fabrication machine — after you model them in MLCad. The sped up video is nothing short of impressive."

Degraded Electrodes Observed In Aging Batteries 108

schliz writes "Scientists have identified nanoscale changes in aging lithium-ion batteries that could be responsible for their degradation over time. By dissecting and examining dead batteries, they found that some lithium was irreversibly lost from the positive to negative electrode of dead batteries, and no longer participated in charging and discharging. They discovered that finely-structured nanomaterials on dead batteries' electrodes had coarsened in size, and theorise that the coarsening of the cathode may be responsible for the loss of lithium."

AMD Demos Llano Fusion APU, Radeon 6800 Series 116

MojoKid writes "At a press event for the impending launch of AMD's new Radeon HD 6870 and HD 6850 series graphics cards, the company took the opportunity to provide an early look at the first, fully functional samples of their upcoming 'Llano' processor, or APU (Applications Processer Unit). For those unfamiliar with Llano, it's 32nm 'Fusion' product that integrates CPU, GPU, and Northbridge functions on a single die. The chip is a low-power derivative of the company's current Phenom II architecture fused with a GPU that will target a wide range of operating environments at speeds of 3GHz or higher. Test systems showed the integrated GPU had no trouble running Alien vs. Predator at a moderate resolution with DirectX 11 features enabled. In terms of the Radeon 6800 series, board shots have been unveiled today, as well as scenes from AMD's upcoming tech demo, Mecha Warrior, showcasing the new graphics technology and advanced effects from the open source Bullet Physics library."

WD Launches 3 Terabyte HD 313

MojoKid writes "Today, Western Digital announced the world's highest density hard drive, as they reach the 3TB mark with their newest, 5th generation Caviar Green product. The Caviar Green 3TB serves up a super-sized combination of reduced power consumption, lower operating temperature, and a quieter operation. Unfortunately, if you're still using Windows XP, don't expect your system to make full use of any 3TB drive (yet). The problem is that older operating systems, in combination with a legacy BIOS and master boot record (MBR) partition table scheme, face a barrier at 2.19TB. Existing motherboards utilizing BIOS (non-UEFI), GPT ready operating systems like Windows 7 64-bit, and appropriate storage class drivers, can address the entire capacity of hard drives larger than 2.19TB. Another issue is that a number of host bus adapter (HBA) and chipset vendors don't offer driver support for these types of drives. To provide a solution for this compatibility issue, Western Digital bundles an HBA with the Caviar Green 3TB drive that allows the operating system to use a known driver to correctly support extra large capacity drives. This solution is reportedly just temporary until the rest of the industry catches up."

One Step Closer To Speedier, Bootless Computers 249

CWmike writes "Physicists at the University of California at Riverside have made a breakthrough in developing a 'spin computer,' which would combine logic with nonvolatile memory, bypassing the need for computers to boot up. The advance could also lead to super-fast chips. The new transistor technology, which one lead scientist believes could become a reality in about five years, would reduce power consumption to the point where eventually computers, mobile phones and other electronic devices could remain on all the time. The breakthrough came when scientists at UC Riverside successfully injected a spinning electron into a resistor material called graphene, which is essentially a very thin layer of graphite. The graphene in this case is one-atom thick. The process is known as 'tunneling spin injection.' A lead scientist for the project said the clock speeds of chips made using tunneling spin injection would be 'thousands of times' faster than today's processors. He describes the tech as a totally new concept that 'will essentially give memory some brains.'"

Small Startup Prevails In Server Cooling 'Chill Off' 45

miller60 writes "A small startup has shown exceptional energy efficiency in a data center 'chill off' comparing server cooling technologies. Clustered Systems posted the best numbers in the 18-month vendor evaluation sponsored by the Silicon Valley Leadership Group. The Menlo Park, Calif. company built a prototype server that uses no fans and cools processors with a cold plate with tubing filled with liquid coolant. The testing accidentally highlighted the opportunity for additional energy savings, when the Clustered Systems unit continued to operate during a cooling failure that raised the chiller plant water temperature from 44 to 78 degrees F."

Cooking With Your USB Ports Screenshot-sm 188

tekgoblin writes "Wow, I would never have thought to try and cook food with the power that a standard USB port provides, but someone did. A standard port provides 5V of power, give or take a little. I am not even sure what it takes to heat a small hotplate, but I am sure it is more than 5V. It looks like the guy tied together around 30 USB cables powered by his PC to power this small hotplate. But believe it or not, it seems to have cooked the meat perfectly."

4G vs. 3G vs. WiFi Throughput For Samsung's Epic 4G 103

MojoKid writes "Some of the most popular Android smartphones currently available are members of Samsung's Galaxy S line. Powered by Samsung's own 1GHz ARM Cortex A8-based Hummingbird processor with a four-inch Super-AMOLED capacitive touchscreen, it's no wonder Samsung has sold over 5 million Galaxy S phones. The Epic 4G variant of this phone, available through Sprint, is also one of the scant few 4G capable devices on the market currently. Sprint's 4G network utilizes WiMAX mobile broadband, with a theoretical maximum throughput of 40Mbps. Sprint claims that the average download speed on its 4G network is between 3 to 6Mbps, with peak download speeds above 10Mbps. The performance figures seen here actually show solid throughput for the Epic, besting competitive 3G devices and even versus some with a Wi-Fi connection. 4G WiMAX service is still rather limited geographically, but hopefully devices like these will help to kick the roll-out into gear a bit."

AOL Spends $1M On Solid State Memory SAN 158

Lucas123 writes "AOL recently completed the roll out of a 50TB SAN made entirely of NAND flash in order to address performance issues with its relational database. While the flash memory fixed the problem, it didn't come cheap, at about four times the cost of a typical Fibre Channel disk array with the same capacity, and it performs at about 250,000 IOPS. One reason the flash SAN is so fast is that it doesn't use a SAS or PCIe backbone, but instead has a proprietary interface that offers up 5 to 6Gb/s throughput. AOL's senior operations architect said the SAN cost about $20 per gigabyte of capacity, or about $1 million. But, as he puts it, 'It's very easy to fall in love with this stuff once you're on it.'"

FSF Announces Hardware Endorsement Criteria 273

sveinungkv writes "The Free Software Foundation has announced criteria for the hardware endorsement program 'Respects Your Freedom.' From the announcement: 'The desire to own a computer or device and have full control over it, to know that you are not being spied on or tracked, to run any software you wish without asking permission, and to share with friends without worrying about Digital Restrictions Management (DRM) — these are the desires of millions of people who care about the future of technology and our society. (...) With our endorsement mark and the strong criteria that back it, we plan to bridge that gap and demonstrate to manufacturers that they stand to gain plenty by making hardware that respects people's freedom instead of curtailing it.' While it currently contains some requirements that many may find broader than what they personally need, the remaining criteria would make the FSF endorsement a useful tool when looking for devices that give the owner control over the device they have bought and paid for. The criteria are still open for feedback."

Study Shows Babies Think Friendly Robots Are Sentient 159

seanonymous writes "A study from University of Washington claims that babies think robots are human, so long as the robots are friendly. No word on what evil robots are thought to be. From the article: 'At 18 months old, babies have begun to make conscious delineations between sentient beings and inanimate objects. But as robots get more and more advanced, those decisions may become harder to make. What causes a baby to decide a robot is more than bits of metal? As it turns out, it takes more than humanoid looks — babies rely on social interaction to make that call.'"

Unspoofable Device Identity Using Flash Memory 145

wiredmikey writes with a story from Security Week that describes a security silver lining to the inevitable errors that arise in NAND flash chips. By seeking out (or intentionally causing) defects in a given part of the chip, a unique profile can be created for any device using NAND flash which the author says may be obscured, but not reproduced: "[W]e recognize devices (or rather: their flash memory) by their defects. Very much like humans recognize faces: by their defects (or deviations from the 'norm') a bigger nose, a bit too bushy eyebrows, bigger cheeks. The nice twist is that if an attacker manages to read your device identity, he cannot inscribe it into his own device. Yes, he can create errors — like we did. But he cannot control where in the block they occur as this relies solely on microscopic manufacturing defects in the silicon."

Huge Shocker — 3D TVs Not Selling 535

itwbennett writes "It comes as no surprise to the vast majority of us who haven't rushed out to buy a 3D TV, but according to a DisplaySearch report consumers aren't doing their part to make 2010 the year of 3D TV, says blogger Peter Smith. And the stats are even worse than Smith imagined they'd be: 'DisplaySearch estimates that 3.2 million 3D TVs will be shipped in 2010. Note, that's shipped, not sold. 3.2 million equates to 2% of all flat panel displays shipped (as far as I can ascertain, that's worldwide shipments). So yeah, there are not many 3D TVs being shipped this year. But wait, that's not the end of the bad news. In Western Europe (the only region where they offered this data point) sales of 3D glasses are less than 1 per 3D set sold. In other words, a lot of Western Europeans who buy a TV with 3D capability don't even bother to buy the glasses to use that feature.'"

Erasing Objects From Video In Real Time 175

Smoothly interpolating away objects in still pictures is impressive enough, but reader geoffbrecker writes with a stunning demonstration from Germany's Technical University of Ilmenau of on-the-fly erasure of selected objects in video. Quoting: "The effect is achieved by an image synthesizer that reduces the image quality, removes the object, and then increases the image quality back up. This all happens within 40 milliseconds, fast enough that the viewer doesn't notice any delay."

Pirate Electrician Supplied Power To 1,500 Homes 373

fridaynightsmoke writes "A former electrical engineer for utility EDF has been prosecuted for illegally supplying power to some 1,500 homes in north London. Derek Brown, 45, was arrested in 2008 after being seen tampering with the electric grid in a manhole. He specialized in connecting separate supplies to houses that were split into apartments. One landlord involved, Haresh Parmar, was jailed for 9 months for stealing £30,000 worth of electricity for 22 of his apartments. Brown's assets will be seized and he has been sentenced to 8 months suspended, and 150 hours community service."

When You Really, Really Want to Upgrade a Tiny Notebook 104

Benz145 writes "The famous Sony VAIO UX UMPC may have been cancelled a few years back by Sony, but the community at Micro PC Talk won't let it die. Modder Anh has carefully removed the relatively slow 1.33Ghz Core Solo CPU and installed a much faster Intel Core 2 Duo U7700 (a process which involves reballing the entire CPU). On top of this, he managed to install an incredibly small 4-port USB hub into the unit which allowed for the further instillation of a Huawei E172 modem for 3G data/voice/SMS, a GPS receiver, and a Pinnacle HD TV receiver. All of this was done without modifying the device's tiny external case. Great high-res pictures of the motherboard with the modded hardware can be seen through the link."
