Boost a Weak 3G Modem Signal, With a Saucepan 146

modeca writes "Using only commonly available kitchen equipment this guy demonstrates the amazing powers of an ordinary metal pan to boost the 3G reception of his USB modem. It really seems to work, check the right hand side of the graph in the video." It's not that crazy: cheap antenna boosting (for USB WiFi dongles, Bluetooth, and more) has been elevated to a fine art in New Zealand.

Impressive Robot Hand From Shadow 101

kkleiner writes "The Shadow Dextrous Hand is a robotic arm that allows for fine motor control and precise movements. It's accurate enough to pick up an egg, screw in a light bulb, or thread a needle. Even cooler, researchers can control it with a 'Cyber glove,' allowing for 24 distinct human movements that mimic the user's own hand. A British based company, Shadow, has been displaying the hand for several years now, and recently demonstrated its latest model at IREX 2009. The hand, toted as the world's most advanced, is available for sale to researchers (pricing has not been made public)."

Midwest Seeing Red Over 'Green' Traffic Lights 839

theodp writes "Many municipalities have switched to LED traffic signals because they burn brighter, last longer and use 90% less energy than incandescent bulbs. But they also emit less heat, meaning they sometimes have trouble melting snow, causing problems across the Midwest. In Wisconsin, snow blanketed LED traffic lights in some towns, leading to crashes at intersections where drivers weren't sure whether to stop or go. The unintended consequences of the green technology were also identified as a 'contributing factor' in the death of an Illinois woman hit by a driver who blamed the snow-covered energy-efficient signal for giving the appearance of a normal green light instead of a left-turn signal. 'We can remove the snow with heat, but the cost of doing that in terms of energy use has not brought any enthusiasm from cities and states that buy these signals,' said the CEO of an LED traffic-signal manufacturer. 'They'd like to be able to take away this issue, but they don't want to spend the money and lose the savings.' In the meantime, some towns are addressing sporadic problems by dispatching crews to remove snow or ice from signals using poles, brooms, and heating devices." We were discussing these recently at the office — several folks in the building are red/green color blind and different street lights are differently distinguishable.

HDD Manufacturers Moving To 4096-Byte Sectors 442

Luminous Coward writes "As previously discussed on Slashdot, according to AnandTech and The Tech Report, hard disk drive manufacturers are now ready to bump the size of the disk sector from 512 to 4096 bytes, in order to minimize storage lost to ECC and sync. This may not be a smooth transition, because some OSes do not align partitions on 4K boundaries."

Skeptics Question OLPC's Focus With $75 Tablet 159

With the recent announcement of OLPC's shift in focus, many are criticizing the nonprofit's attempt to design what could be seen as unrealistic hardware at an impossible price point. "The OLPC project has become an unrealistic hardware 'dream' and lost its focus on education, wrote blogger Wayan Vota on OLPC News, which has followed the OLPC since its inception. The project comes up with unrealistic hardware designs and price points that destroy its purpose even more, he wrote. 'Excuse me if I get mad at the XO-3 hype. I'm angry at the energy devoted to fantasy XO hardware instead of OLPC educational reality. I miss the original OLPC Mission, where children, not computers, controlled our dreams,' Vota wrote."

Wikileaks Needs Help, and Not Just Money 134

st1d writes to tell us that Wikileaks has put out a call for help. However, instead of just asking for money, they have also suggested technical and legal avenues for support. In the site's short life, Wikileaks has been at the center of many breaking scandals and investigations. "Wikileaks is currently overloaded by readers. This is a regular difficulty that can only be resolved by deploying additional resources. If you support our mission, you can help us by integrating new hardware into our project infrastructure or developing software for the project. Become patron of a WikiLeaks server or other parts of our technology, adding more pillars to the stability and balance of the WikiLeaks platform. Servers come trouble-free and legally fortified, software is uniquely challenging. If you can provide rackspace, power and an uplink, or a dedicated server or storage space, for at least 12 months, or software development work for WikiLeaks, please write to wl-supporters@sunshinepress.org."

First Tablet Using Pixel Qi Screen On The Way 97

Azureflare writes "The first device using a Pixel Qi screen has been confirmed. It is produced by Notion Ink, and it appears they took a few design tips from Apple by sticking with a design that has tapered edges. This tablet should give Apple a run for their money, especially considering the recently confirmed rumor of an Apple tablet. 'The Notion Ink smartpad measures 6.3 x 9.8 x 0.6 inches and weighs 1.7lbs; as well as the tri-band (850/1900/2100) UMTS/HSDPA, WiFi b/g and Bluetooth 2.1+EDR it also squeezes in A-GPS, a digital compass, accelerometer and proximity, ambient light and water sensors. Connectivity includes USB, HDMI, a 3.5mm headphone jack and a microphone input, and there’s also a 3-megapixel auto-focus camera with video recording support. Onboard storage is either 16GB or 32GB of SSD, and there's an SD slot for augmenting that.'" Update: 12/25 21:44 GMT by SS : Removed erroneous reference to Nokia.

The Best Robots of 2009 51

kkleiner writes "Singularity Hub has just unveiled its second annual roundup of the best robots of the year. In 2009 robots continued their advance towards world domination with several impressive breakouts in areas such as walking, automation, and agility, while still lacking in adaptability and reasoning ability. It will be several years until robots can gain the artificial intelligence that will truly make them remarkable, but in the meantime they are still pretty awesome."

Best Filesystem For External Back-Up Drives? 484

rufey writes "I've recently embarked on a project to rip my DVD and CD collection to a pair of external USB drives. One drive will be used on a daily basis to access the rips of music and DVDs, as well as store backups of all of my other data. The second drive will be a copy of the first drive, to be synced up on a monthly basis and kept at a different location. The USB drives that I purchased for this are 1 TB in size and came pre-formatted with FAT32. While I can access this filesystem from all of my Windows and Linux machines, there are some limitations." Read on for the rest, and offer your advice on the best filesystem for this application.

Typing With Your Brain 262

destinyland writes "This article asks, 'Why bother to type a document using a keyboard when you can write it by simply thinking about the letters?' A brain wave study presented at the 2009 annual meeting of the American Epilepsy Society shows that people with electrodes in their brains can 'type' using just their minds. The study involved electrocorticography — a sheet of electrodes laid directly on the surface of the brain after a surgical incision into the skull. ('We were able to consistently predict the desired letters for our patients at or near 100 percent accuracy,' explains one Mayo clinic neurologist.) And besides typing, there's new brain wave applications that can now turn brain waves into music and even Twitter status updates — by thought alone."

Body Heat Energy Generation 214

BuzzSkyline writes "Researchers in Belgium have developed devices to harvest the waste heat our bodies throw off in order to convert it to electricity to run devices such as a wristband blood oxygen sensor and an electrocardiogram shirt. As a side benefit, the power sources help cool you down and keep you looking cool, all while running sundry micropower devices. In fact, the researchers mention that the energy harvesting head band works so well that it can get uncomfortably cold. In that case, they say, 'This problem is solved in exactly the same way as someone solves it on the body level in cold weather: a headgear should be worn on top of the system to limit the heat flow and make it comfortable.' But it would be such a shame to cover up the golden heat-harvesting headband with a hat."

Intel Patches Flaws In Trusted Execution Tech 84

An anonymous reader writes "Joanna Rutkowska's company Invisible Things Lab has issued the results of their research into flaws in Intel's Trusted Execution Technology (TXT), whose function is to provide a mechanism for safe loading of system software and to protect sensitive files. ITL describes how flaws in TXT can be used to compromise the integrity of a software loaded via an Intel TXT-based loader in a generic way, fully circumventing any protection TXT is supposed to provide. The attack exploits an implementation error in the so-called SINIT Authenticated Code modules and that could potentially allow a malicious attacker to elevate their privileges. Intel has released a patch for the affected chipsets, which include the Q35, GM45, PM45 Express, Q45, and Q43 Express." Here are ITL's press release (PDF) and Intel's advisory.

Nuclear Reactors As Art 118

Hemos recommends the coverage over at Wired of a project to digitize nuclear reactor art. "Not all nuclear reactors are built alike. Power plant designs can vary in their fuels, coolants, and configurations, a fact beautifully illustrated by a series of reactor wall charts originally published in issues of Nuclear Engineering International during the 1970s and 1980s. Since then, the charts have been lovingly collected by Ronald Knief, a nuclear engineer at Sandia National Laboratory. Recently, he completed his collection... and began to digitize the drawings. The first eight out of more than 100 have now been permanently archived online... 'This is not a CAD/CAM-type thing,' Knief said. 'This really is art.'"

CherryPal's $99 "Odd Lots" Netbook 234

Robotech_Master writes "CherryPal, which Slashdot last covered back in 2008, has released a $99 netbook, the Africa, aimed at the developing world but (unlike the OLPC) available for sale to the consumer. But unlike most netbooks, the Africa is not actually made to a set design. Instead, it uses a hacker-like approach similar to the way home PC builders build their cheap beige boxes. CherryPal purchases odd lots of whatever components are available most inexpensively, builds netbooks out of them, and calls them Africas. The resulting machines will at least meet and may exceed the minimum specs given on CherryPal's website, and may be built around an ARM, MIPS, or X86-based CPU depending on what parts CherryPal has on hand at the time. The device ships with 'at least' Windows CE or CherryPal's custom 'Green Maraschino' Debian-based Linux distro."
