A Simple DIY Game Controller For People With Physical Challenges 36

Posted by Soulskill from the accessibility-is-king dept.
capedgirardeau writes "Caleb Kraft of the well-known Hack-A-Day site noticed that game controllers and alternate keyboards for people with physical challenges were very expensive. Simple switches for buttons that could be made for a few dollars were running $60 or $70 apiece. Working with a young man he knew who loves gaming and has muscular dystrophy, Caleb created a do-it-yourself controller for people with physical challenges using a 3-D printer, a super-cheap micro-controller board and some simple keyboard emulation software. He is freely releasing all the 3-D printer files and tutorials to make his and other controllers on a new site, The Controller Project. He also encourages people to check out The AbleGamers Foundation"

Tesla To Build Its Own Battery-Swap Stations 377

Posted by Soulskill from the can-somebody-please-make-this-for-phone-batteries dept.
New submitter lfp98 writes "Just a month after the collapse of independent battery-swap company Better Place, the uniquely successful maker of luxury electric cars, Tesla, has announced it will provide its own battery-swap capability for its Model S sedans. The first stations will be built adjacent to Tesla's charging stations on the SF-to-LA route, and a swap will take no longer than filling a gas tank. From the article: 'A battery pack swap will cost between $60 and $80, about the same as filling up a 15-gallon gas tank,' Musk said. 'Drivers who choose to swap must reclaim their original battery on their return trip or pay the difference in cost for the new pack.'"

New Technique For Optical Storage Claims 1 Petabyte On a Single DVD 182

Posted by samzenpus from the that's-a-long-movie dept.
melios writes "Using a two-light-beam method a company claims to have overcome Abbe's Law to dramatically increase the storage density for optical media, to the 9 nm scale. From the article: 'The technique is also cost-effective and portable, as only conventional optical and laser elements are used, and allows for the development of optical data storage with long life and low energy consumption, which could be an ideal platform for a Big Data centre.'"

A Look At Quantum Computer Manufacturer D-Wave and Its Founder 96

Posted by samzenpus from the road-ahead dept.
First time accepted submitter tpjunkie writes "Many slashdot readers will remember D-wave's announcement in 2007 of its quantum computer, an announcement met with skepticism and a good amount of scorn. However, today the company has sold quantum computers to such companies as Lockheed Martin and Google, and their computers have gone from a handful of qubits to 512 in their most recent offerings. Nature has a story including an interview with the company's founder Geordi Rose, and a look at where the company is headed and some of the difficulties it has overcome."

jfruh writes "Foxconn is firmly identified in the public mind as the company that manufactures iPhones and iPads. But the company is looking to forge its own identity, and sees Firefox OS as the means to do so. To that end, Foxconn is hiring thousands of developers to help work on the open source phone OS and Foxconn's own suite of cloud services."

Ask Slashdot: Does LED Backlight PWM Drive You Crazy? 532

Posted by timothy from the it's-how-they-send-messages dept.
jones_supa writes "I would like to raise some discussion about a hardware issue that has increasingly started to bug me: backlight flicker, from which many LED-backlit monitors suffer. As you might know, the backlight and its dimming is driven by a pulse width modulated square wave, essentially flicking the LEDs on and off rapidly. Back in the CRT days a 100Hz picture was deluxe, due to the long afterglow of the display phosphor. LEDs, however, shut off immediately and my watering eyes and headache tell that we should be using frequencies in multiple kHz there. Unfortunately we too often fall behind that. As one spark of hope, the display review site PRAD has already started to include backlight signal captures to help assessing the problem. However with laptops and various mobile gadgets, finding this kind of information is practically impossible. This issue sort of lingers in the background but likely impacts the well-being of many, and certainly deserves more attention." So do LEDs bother your eyes? I think CRTs gave me headaches far more often than has any form of flat panel display, at least partly because of the whining noise that CRTs emit.

Next SurfaceRT To Come With Qualcomm Snapdragon 800, LTE 157

Posted by timothy from the market-is-a-harsh-mistress dept.
recoiledsnake writes "Following up on our previous discussion of Microsoft selling discounted SurfaceRT tablets to schools (which fueled speculation about the future of Surface RT), Bloomberg is now reporting that Microsoft is fast at work on the next Surface RT which will replace the current Tegra 3 with a Qualcomm Snapdragon 800 chip which has stellar benchmarks against the likes of the upcoming Tegra 4, Apple A6X, and Exynos processors, especially in the GPU and graphics department. Since the SoC comes with 3g/LTE, this might be the first Surface to support integrated cellular data. There are also indications that there could be an 8" version, and that the new versions might be revealed alongside the Windows 8.1 preview bits at the upcoming BUILD conference, starting on June 26."

The Plight of Star Wars Droids 245

Posted by Soulskill from the george-lucas-doesn't-care-about-metal-people dept.
malachiorion writes "Does George Lucas hate metal people? I know, sounds like standard click-bait, but I think I present a relatively troll-free argument in the piece I wrote for Slate. We stuck to the Star Wars canon, pointing out the relatively grim state of affairs for droid rights, and the lack of any real sympathy for their plight from the heroes, or, it would seem, George Lucas. C-3PO is more correct than he might realize, when the says that droids 'seem to be made to suffer.'"

Cat-like Robot Runs Like the Wind 69

Posted by Soulskill from the played-by-peter-weller's-cat dept.
DeviceGuru writes "Researchers at the Biorob lab at Switzerland's École Polytechnique Fédérale de Lausanne (EPFL), have announced a cat-like robot that is claimed to be the fastest quadruped robot under 30 kilograms. The Cheetah-cub Robot, which runs real-time Xenomai Linux on an x86-based RoBoard robot control board, mimics the biomechanics of a cat to increase the speed and stability of it quadroped legs, helping it achieve speeds of 1.42m/s. The goal of the still-early-stage project is to encourage research in biomechanics, with an aim toward building faster robots for search and rescue, or ground exploration. More info is available on EPFL's Cheetah page."

Revisiting Amdahl's Law 54

Posted by Soulskill from the looking-for-new-loopholes dept.
An anonymous reader writes "A German computer scientist is taking a fresh look at the 46-year old Amdahl's law, which took a first look at limitations in parallel computing with respect to serial computing. The fresh look considers software development models as a way to overcome parallel computing limitations. 'DEEP keeps the code parts of a simulation that can only be parallelized up to a concurrency of p = L on a Cluster Computer equipped with fast general purpose processors. The highly parallelizable parts of the simulation are run on a massively parallel Booster-system with a concurrency of p = H, H >> L. The booster is equipped with many-core Xeon Phi processors and connected by a 3D-torus network of sub-microsecond latency based on EXTOLL technology. The DEEP system software allows to dynamically distribute the tasks to the most appropriate parts of the hardware in order to achieve highest computational efficiency.' Amdahl's law has been revisited many times, most notably by John Gustafson."

NVIDIA To License Its GPU Tech 111

Posted by Soulskill from the sea-change dept.
An anonymous reader writes "Today in a blog post, NVIDIA's General Counsel, David Shannon, announced that the company will begin licensing its GPU cores and patent portfolio to device makers. '[I]t's not practical to build silicon or systems to address every part of the expanding market. Adopting a new business approach will allow us to address the universe of devices.' He cites the 'explosion of Android devices' as one of the prime reasons for this decision. 'This opportunity simply didn't exist several years ago because there was really just one computing device – the PC. But the swirling universe of new computing devices provides new opportunities to license our GPU core or visual computing portfolio.' Shannon points out that NVIDIA did something similar with the CPU core used in the PlayStation 3, which was licensed to Sony. But mobile seems to be the big opportunity now: 'We'll start by licensing the GPU core based on the NVIDIA Kepler architecture, the world's most advanced, most efficient GPU. Its DX11, OpenGL 4.3, and GPGPU capabilities, along with vastly superior performance and efficiency, create a new class of licensable GPU cores. Through our efforts designing Tegra into mobile devices, we've gained valuable experience designing for the smallest power envelopes. As a result, Kepler can operate in a half-watt power envelope, making it scalable from smartphones to supercomputers.'"

Oculus Rift Raises Another $16 Million 104

Posted by Soulskill from the all-about-the-benjamins dept.
Craefter writes "It seems that the Oculus Rift virtual-reality headset caught the attention of investors after its showing at E3 this year. Spark Capital and Matrix Partners were able to push $16 million at Oculus VR in the hopes that the product will live up to the hype. The HD unit looks a bit more slick than the ski-goggles-with-a-tablet-glued-to-it prototype, but the device would look even more appealing if the next-gen consoles would commit to supporting it. (We all know how well the PS3's 'wave-stick' did as an afterthought.) That said, major titles like the 9-year-old Half-Life 2 and the 6-year-old Team Fortress 2 are getting full support for the device. Hopefully some developers are looking into support for the Oculus Rift as a launch feature, rather than an addition years after the fact. IA bit like the EAX standard from Soundblaster. That worked out well too."

With an Eye Toward Disaster, NYC Debuts Solar Charging Stations 115

Posted by Soulskill from the it's-always-sunny-in-new-york-city dept.
Nerval's Lobster writes "When hurricane Sandy pummeled New York City last fall, it left a sizable percentage of the metropolis without electricity. Residents had trouble keeping their phones and tablets charged, and often walked across whole neighborhoods to reach zones with power. Come the next disaster, at least a few citizens could communicate a little easier thanks to 25 solar-powered charging stations going up around the city. The stations—known as 'Street Charge' — are the result of a partnership between AT&T, Brooklyn design studio Pensa, and portable solar-power maker Goal Zero (with approval by the city's Parks Department). The first unit will deploy in Brooklyn's Fort Green Park on June 18, followed in short order by others in Union Square, Central Park, the Rockaways, and other locations. Each station incorporates lithium-ion batteries in addition to solar panels; charging a phone to full capacity could take as long as two hours, but the time necessary for a partial charge is much shorter. But a couple of charging stations also won't help very much if half the city is without power: In order to help mitigate the effects of the next hurricane, New York City major Michael Bloomberg has put forward a $20 billion plan for seawalls, levees, and dozens of other improvements. 'Sandy exposed weaknesses in the city's telecommunications infrastructure — including the location of critical facilities in areas that are susceptible to flooding,' reads one section of the plan's accompanying report. The city will harden the system 'by increasing the accountability of telecommunications providers to invest in resiliency and by using new regulatory authority to enable rapid recovery after extreme weather events.'"

Jon 'Maddog' Hall On Project Cauã: a Server In Every Highrise 151

Posted by timothy from the cafeterias-and-slaughterhouses-too dept.
Qedward writes with an excerpt at TechWorld about a new project from Jon "Maddog" Hall, which is about to launch in Brazil: "The vision of Project Cauã is to promote more efficient computing following the thin client/server model, while creating up to two million privately-funded high-tech jobs in Brazil, and another three to four million in the rest of Latin America. Hall explained that Sao Paolo in Brazil is the second largest city in the Western Hemisphere and has about twelve times the population density of New York City. As a result, there are a lot of people living and working in very tall buildings. Project Cauã will aim to put a server system in the basement of all of these tall buildings and thin clients throughout the building, so that residents and businesses can run all of their data and applications remotely."

TiVo Series 5 Coming This Fall 178

Posted by timothy from the are-there-even-six-bladed-razors-yet? dept.
WebGangsta writes "The rumor mill continues to grow closer and closer to reality, as The Verge is reporting the upcoming SERIES 5 TiVo will have 6 tuners, support OTA recording (an old TiVo feature being brought back), storage beyond the 2TB limit, and more. While some would say that TiVo today is nothing more than a Patent Holder (albeit a successful one), there's still a market for a cable box that doubles as a streaming player. Is hardware the future of TiVo, or should they go and just license their software to all? And don't get us started on those 'TiVo Buying Hulu' or 'Apple/Google buying TiVo' rumors... that's a different story for a different day."

Intel Announces New Enterprise Xeons, More Powerful Xeon Phi Cards 57

Posted by Unknown Lamer from the send-me-ten dept.
MojoKid writes "Intel announced a set of new enterprise products today aimed at furthering its strengths in the TOP500 supercomputing market. As of today, the Chinese Tiahne-2 supercomputer (aka Milky Way 2) is now the fastest supercomputer on the planet at roughly ~54PFLOPs. Intel is putting its own major push behind heterogeneous computing with the Tianhe-2. Each node contains two Ivy Bridge sockets and three Xeon Phi cards. Each node, therefore, contains 422.4GFLOP/s in Ivy Bridge performance — but 3.43TFLOPs/s worth of Xeon Phi. In addition, we'll see new Xeons based on this technology later this year, in the 22nm E5-2600 V2 family, with up to 12 cores. The new chips will be built on Ivy Bridge technology and will offer up to 12 cores / 24 threads. The new Xeons, however, aren't really the interesting part of the story. Today, Intel is adding cards to the current Xeon Phi lineup — the 7120P, 3120P, 3120A, and 5120D. The 3120P and 3120A are the same card — the 'P' is passively cooled, while the "A" integrates a fan. Both of these solutions have 57 CPUs and 6GB of RAM. Intel states that they offer ~1TFLOP of performance, which puts them on par with the 5110P that launched last year, but with slightly less memory and presumably a lower price point. At the top of the line, Intel is introducing the 7120P and 7120X — the 7120P comes with an integrated heat spreader, the 7120X doesn't. Clock speeds are higher on this card, it has 61 cores instead of 60, 16GB of GDDR5, and 352GBps of memory bandwidth. Customers who need lots of cores and not much RAM can opt for one of the cheaper 3100 cards, while the 7100 family allows for much greater data sets."

SanDisk Focusing More On Desktop and Mobile SATA SSDs, Extreme II Series Tested 71

Posted by samzenpus from the trying-it-out dept.
MojoKid writes "Odds are, if you've purchased anything that uses Flash memory in the last 20 years or so, you already own a piece of SanDisk technology. The company has been in Flash storage since the late '80s and manufactures products used in everything from smartphones to digital cameras. Even though it enjoys a long history in the Flash memory business, SanDisk is perhaps not as well known for its Solid State Drive (SSD) solutions for desktop and mobile PCs. However, SanDisk recently expanded their product stack with new, high-performance SSDs that leverage the company's own NAND Flash memory and Marvell's popular 88SSS9187 controller. The new drives are SanDisk's Extreme II family of SSDs targeted performance enthusiasts, workstations professionals and gamers. The initial line-up of drives consists of 120GB, 240GB, and 480GB models. Performance specifications for the three drives come in at 545MB/s – 550MB/s for reads with write performance from 340MB/s to 510MB/s, depending on density. In the benchmarks, SanDisk's Extreme II SSD showed it has the chops to hang with some of the fastest drives on the market from Samsung, Corsair and OCZ."

Helicopter Parts Make For Amazing DIY Camera Stabilization 78

Posted by timothy from the so-you'll-be-checking-luggage-then dept.
Iddo Genuth writes "Videographer Tom Antos developed an advanced DIY camera stabilizer which can hold almost any DSLR or mirrorless camera steady for video photography. Although this surely isn't as sophisticated (and super expensive) as the professional MVI M10 handheld 3-axis digital stabilized camera gimbal, its still quite impressive especially when you consider it only costs a few hundred dollars rather then tens of thousands — that is if you feel like building it yourself." Antos' design takes advantage of stabilized gimbal systems made for hanging cameras on remote-controlled helicopters, and does a very impressive job for its price.

Robot Dominates Air Hockey, Adapts To Opponents' Playing Style 49

Posted by timothy from the bet-on-the-robot-kid dept.
colinneagle writes "Researchers at Chiba University in Japan have developed a robot that could frustrate teenagers worldwide with its impressive air hockey skills. What's remarkable about this air hockey-playing robot, which is not the first of its kind, is that it can sense human opponents' playing styles and adapt to defend against them. The key is how the computer controlling the robot views its opponent — at a speed of 500 frames per second. From there, the robot uses a three-layer control system to determine motion control, when it should hit the puck, defend its goal or stay still, and a third that determines how it should react to its opponent's playing style."
