Consumers Not Impressed With 3D Printing

Unknown Lamer posted 7 hours ago | from the drip-coffee-and-widget-maker dept.

220

Lucas123 (935744) writes "Putting a 3D printer beside the coffee maker in every home, as some manufacturers hope will happen someday, is a long ways from reality as consumers today still don't understand how the technology will benefit them, according to a new study. The study, by Juniper Research, states that part of the problem is that killer applications with the appropriate eco-system of software, apps and materials have yet to be identified and communicated to potential users. And, even though HP has announced its intention to enter the 3D printing space (possibly this fall) a massive, mainstream corporation isn't likely to change the market."

DIY Wearable Pi With Near-Eye Video Glasses

coop0030 (263345) writes "Noe & Pedro Ruiz at Adafruit have created a pair of open source near-eye video glasses combined with a Raspberry Pi. Their 3D Printed design turns a pair of 'private display glasses' into a "google glass"-like form factor. It easily clips to your prescription glasses, and can display any kind of device with Composite Video like a Raspberry Pi. They have a video demonstrating the glasses, a tutorial on how to build them, along with the 3d files required to print it out."

Previously Unknown Warhol Works Recovered From '80s Amiga Disks

First time accepted submitter mooterSkooter (1132489) writes "Magnetic Imaging tools were used to recover a dozen images produced by Andy Warhol on his Amiga computer. I would've just stuck the disks in and tried to copy it myself." Read more about it from the Frank Ratchye Studio for Creative Inquiry, which says "The impetus for the investigation came when [artist Cory] Arcangel, a self-described “Warhol fanatic and lifelong computer nerd,” learned about Warhol’s Amiga experiments from the YouTube video of the 1985 Commodore Amiga product launch. Acting on a hunch, and with the support of CMOA curator Tina Kukielski, Arcangel approached the AWM in December 2011 regarding the possibility of restoring the Amiga hardware in the museum’s possession, and cataloging any files on its associated diskettes. In April 2012, he contacted Golan Levin, a CMU art professor and director of the FRSCI, a laboratory that supports “atypical, anti-disciplinary and inter-institutional” arts research. Offering a grant to support the investigation, Levin connected Cory with the CMU Computer Club, a student organization that had gained renown for its expertise in “retrocomputing,” or the restoration of vintage computers."

WRT54G Successor Falls Flat On Promises

New submitter JImbob0i0 writes: "Back in January, Linksys/Belkin made a big deal about their new router, the WRT1900AC, which they claimed was a successor to the venerable WRT54G, and how they were working with OpenWRT. They released it this week, but their promises have fallen far short. You need to apply patches (which don't apply cleanly) and compile yourself in order to get it to work... so long as you don't need wireless support. There has not been much response from Linksys on the mailing list to criticism of the improperly formatted patch dump and poor reviews as a result."

Google's Project Ara Could Bring PC-Like Hardware Ecosystem To Phones

Soulskill posted 2 days ago | from the without-the-liquid-cooling-i-hope dept.

An anonymous reader writes "Now that Google's modular phone effort, Project Ara, looks a bit less like vaporware, people are starting to figure out its implications for the future of cellphones. One fascinating possibility is that it could transform the cellphone purchasing process into something resembling desktop computer purchasing. Enthusiasts could search out the individual parts they like the best and assemble them into cellphone Voltron. People who just want a decent phone with no hassle could look at pre-built offerings — and not just from Apple, Samsung, and the like. It could open up a whole new group of phone 'manufacturers.' Of course, this comes with drawbacks, too — if you think fragmentation is bad now, imagine trying to support thousands of different hardware combinations."

Will the Nissan Leaf Take On the Tesla Model S At Half the Price?

timothy posted 2 days ago | from the need-more-juice dept.

cartechboy (2660665) writes "Ask most people why they won't consider an electric car, and they talk about range anxiety. And I can easily imagine why 84 miles of range isn't enough. Now it sounds like Nissan is listening, as well as watching Tesla's success. The company plans to boost the Leaf electric car's driving range with options for larger battery packs. Not long ago Nissan surveyed Tesla Model S owners, and they probably heard loud and clear that longer driving range is very, very important. So it looks like the Leaf might get up to 150 miles of range, possibly by the 2016 model year. The range increase will come from a larger battery pack, possibly 36 or 42 kWh, and more energy-dense cells. Either way, clearly Nissan is looking to expand the appeal of the world's best-selling electric car, and increasing its driving range is pretty clearly a key to doing so. I just wish Nissan would ditch the weird styling while they're at it."

Oklahoma Moves To Discourage Solar and Wind Power

samzenpus posted 3 days ago | from the who-needs-the-sun? dept.

Hugh Pickens DOT Com (2995471) writes "Paul Monies reports at NewsOK that Oklahoma's legislature has passed a bill that allows regulated utilities to apply to the Oklahoma Corporation Commission to charge a higher base rate to customers who generate solar and wind energy and send their excess power back into the grid reversing a 1977 law that forbade utilities to charge extra to solar users. 'Renewable energy fed back into the grid is ultimately doing utility companies a service,' says John Aziz. 'Solar generates in the daytime, when demand for electricity is highest, thereby alleviating pressure during peak demand.'

The state's major electric utilities backed the bill but couldn't provide figures on how much customers already using distributed generation are getting subsidized by other customers. Oklahoma Gas and Electric Co. and Public Service Co. of Oklahoma have about 1.3 million electric customers in the state. They have about 500 customers using distributed generation. Kathleen O'Shea, OG&E spokeswoman, said few distributed generation customers want to sever their ties to the grid. 'If there's something wrong with their panel or it's really cloudy, they need our electricity, and it's going to be there for them,' O'Shea said. 'We just want to make sure they're paying their fair amount of that maintenance cost.' The prospect of widespread adoption of rooftop solar worries many utilities. A report last year by the industry's research group, the Edison Electric Institute, warns of the risks posed by rooftop solar (PDF). 'When customers have the opportunity to reduce their use of a product or find another provider of such service, utility earnings growth is threatened," the report said. "As this threat to growth becomes more evident, investors will become less attracted to investments in the utility sector.''"

AMD Not Trying To Get Its Chips Into Low-Cost Tablets

jfruh (300774) writes "While Intel is going after low-end Android tablets in a big way chipmaking x86 rival AMD is taking a more judicious approach, looking to focus on the high end. 'This idea of contra revenue is foreign to us,' said AMD's CEO, referring to Intel's strategy of selling chips at a loss to boost market share. But will Intel's vast resources keep AMD in its niche?"

Why Tesla Really Needs a Gigafactory

timothy posted 4 days ago | from the if-only-there-were-fast-swap-stations-everywhere dept.

192

Hodejo1 (1252120) writes "Tesla has already put over 25,000 cars on the road with more to come and, presumably, most will still be running well past the 8-year battery warranty. What would happen if it is time to replace the battery pack on an old Model S or X and the cost is $25K? Simple, it would destroy the resale value of said cars, which would negatively affect the lease value of new Tesla automobiles. That's a big part of the real reason why Tesla is building its own battery factory. They not only need to ensure enough supply for new cars, but they have to dramatically bring down the price of the replacement batteries low enough so owners of otherwise perfectly running old Teslas don't just junk them. The Tesla Roadster was not a mass produced vehicle, so the cost of replacing its battery is $40K. The economies of scale of a gigafactory alone will drop battery costs dramatically. Heavy research could drop it further over the next decade or so."

Google's New Camera App Simulates Shallow Depth of Field

timothy posted 5 days ago | from the give-your-mom-an-easter-bokeh dept.

New submitter katiewilliam (3621675) writes with a story at Hardware Zone about a new feature that Google's working on for Android phones' built-in cameras: the illusion of shallow depth of field in phone snapshots, which typically err on the side of too much in focus, rather than too little. Excerpting: "The Google Research Blog [note: here's a direct link] revealed that there's quite a fair bit of algorithms running to achieve this effect; to put it in a nutshell, computer vision algorithms create a 3D model of the world based on the shots you have taken, and estimate the depth to every point in the scene."

For $20, Build a VR Headset For Your Smartphone

An anonymous reader writes "Not everyone can drop a few hundred dollars on a VR headset, but that doesn't mean they can't experience VR! For those with the time and a bit of handiwork skill, this DIY guide from guest writer Ohaple will show you how to make a smartphone-based VR headset for as little as $20. Along the way, you'll learn the hardware and software basics of a VR headset." This project screams for a ready-made commercial version; does anyone know of existing purpose-built headgear? As one of the comments on the linked tutorial says, Poppy seems close, but lacks an LED for tracking.

Microsoft Plans $1 Billion Server Farm In Iowa

1sockchuck (826398) writes "Microsoft will invest $1.1 billion to build a massive new server farm in Iowa, not far from an existing data center in West Des Moines. The 1.2 million square foot campus will be one of the biggest in the history of the data center industry. It further enhances Iowa's status as the data center capital of the Midwest, with Google and Facebook also operating huge server farms in the state."

MIT Designs Tsunami Proof Floating Nuclear Reactor

samzenpus posted about a week ago | from the riding-the-waves dept.

First time accepted submitter Amtrak (2430376) writes "MIT has created designs for a nuclear plant that would avoid the downfall of the Fukushima Daiichi plant. The new design calls for the nuclear plant to be placed on a floating platform modeled after the platforms used for offshore oil drilling. A floating platform several miles offshore, moored in about 100 meters of water, would be unaffected by the motions of a tsunami; earthquakes would have no direct effect at all. Meanwhile, the biggest issue that faces most nuclear plants under emergency conditions — overheating and potential meltdown, as happened at Fukushima, Chernobyl, and Three Mile Island — would be virtually impossible at sea."

Ask Slashdot: Which Router Firmware For Bandwidth Management?

timothy posted about a week ago | from the but-the-neighbors-will-object dept.

104

First time accepted submitter DeathByLlama (2813725) writes "Years ago I made the switch from DD-WRT to Tomato firmware for my Linksys router. I lost a couple features, but gained one of the best QoS and bandwidth management systems I have seen on a router to date. Admins can see graphs of current and historical bandwidth usage by IP, set minimum and maximum bandwidth limits by IP range, setup QoS rules, and see and filter graphs and lists of current connections by usage, class or source/destination — all from an elegantly designed GUI. This has allowed me to easily and intelligently allocate and adjust my network's bandwidth; when there is a problem, I can see where it's coming from and create rules around it. I'm currently using the Toastman's VPN Tomato firmware, which has about everything that I would want, except for one key thing: support for ARM-based routers (only Broadcom is supported). I have seen other firmware projects being actively developed in the last few years, so in picking a new 802.11ac router, I need to decide whether Tomato support is a deal-breaker. With solid bandwidth management as a priority, what firmware would you recommend? Stock Asuswrt? Asuswrt-Merlin? OpenWRT? DD-WRT? Tomato? _____?"

SSD-HDD Price Gap Won't Go Away Anytime Soon

storagedude (1517243) writes "Flash storage costs have been dropping rapidly for years, but those gains are about to slow, and a number of issues will keep flash from closing the cost gap with HDDs for some time, writes Henry Newman at Enterprise Storage Forum. As SSD density increases, reliability and performance decrease, creating a dilemma for manufacturers who must balance density, cost, reliability and performance. '[F]lash technology and SSDs cannot yet replace HDDs as primary storage for enterprise and HPC applications due to continued high prices for capacity, bandwidth and power, as well as issues with reliability that can only be addressed by increasing overall costs. At least for the foreseeable future, the cost of flash compared to hard drive storage is not going to change.'"

The Squishy Future of Robotics

An anonymous reader writes "The field of soft robotics is fast growing and may be the key to allowing robots and humans to work side-by-side. 'Roboticists are prejudiced toward rigid structures, for which algorithms can be inherited from the well-established factory robot industry. Soft robots solve two huge problems with current robots, however. They don't have to calculate their movements as precisely as hard robots, which rely on springs and joints, making them better for navigating uncontrolled environments like a house, disaster area, or hospital room. They're naturally "cage free," meaning they can work shoulder-to-shoulder with humans. If a soft robot tips over or malfunctions, the danger is on par with being attacked by a pillow. The robot is also less prone to hurt itself.'"

'Thermoelectrics' Could One Day Power Cars

Soulskill posted about a week ago | from the hot-wheels dept.

sciencehabit writes: "Fossil fuels power modern society by generating heat, but much of that heat is wasted. Researchers have tried to reclaim some of it with semiconductor devices called thermoelectrics, which convert the heat into power. But they remain too inefficient and expensive to be useful beyond a handful of niche applications. Now, scientists in Illinois report that they have used a cheap, well-known material to create the most heat-hungry thermoelectric so far (abstract). In the process, the researchers say, they learned valuable lessons that could push the materials to the efficiencies needed for widespread applications. If that happens, thermoelectrics could one day power cars and scavenge energy from myriad engines, boilers, and electrical plants."

Bill Gates Patents Detecting, Responding To "Glassholes"

Unknown Lamer posted about a week ago | from the fighting-back-against-the-thousand-eyes dept.

theodp (442580) writes "As Google Glass goes on sale [ed: or rather, went on sale] to the general public, GeekWire reports that Bill Gates has already snagged one patent for 'detecting and responding to an intruding camera' and has another in the works. The invention proposes to equip computer and device displays with technology for detecting and responding to any cameras in the vicinity by editing or blurring the content on the screen, or alerting the user to the presence of the camera. Gates and Nathan Myhrvold are among the 16 co-inventors of the so-called Unauthorized Viewer Detection System and Method, which the patent application notes is useful 'while a user is taking public transportation, where intruding cameras are likely to be present.' So, is Bill's patent muse none other than NYC subway rider Sergey Brin?" A more cynical interpretation: closing the analog hole. Vaguely related, mpicpp pointed out that Google filed a patent for cameras embedded in contact lenses.

Lack of US Cybersecurity Across the Electric Grid

Soulskill posted about two weeks ago | from the asking-for-trouble dept.

Lasrick writes: "Meghan McGuinness of the Bipartisan Policy Center writes about the Electric Grid Cybersecurity Initiative, a collaborative effort between the center's Energy and Homeland Security Projects. She points out that over half the attacks on U.S. critical infrastructure sectors last year were on the energy sector. Cyber attacks could come from a variety of sources, and 'a large-scale cyber attack or combined cyber and physical attack could lead to enormous costs, potentially triggering sustained power outages over large portions of the electric grid and prolonged disruptions in communications, food and water supplies, and health care delivery.' ECGI is recommending the creation of a new, industry-supported model that would create incentives for the continual improvement and adaptation needed to respond effectively to rapidly evolving cyber threats. The vulnerability of the grid has been much discussed this last week; McGuinness's recommendations are a good place to start."

How Amazon Keeps Cutting AWS Prices: Cheapskate Culture

timothy posted about two weeks ago | from the mining-the-couch-for-change dept.

An anonymous reader writes "Amazon Web Services has cut its prices on 40-plus consecutive occasions, at times leading the charge, at other times countering similar moves by Microsoft and Google. This article at CRN includes some interesting behind-the-scenes trivia about how Amazon keeps costs down, including some interesting speculation — for example, that perhaps the reason Amazon's Glacier storage is so cheap is that maybe it might be based at least partly on tape, not disk (Amazon would not comment). The article also explains that the company will only pay for its employees to fly Economy, and that includes its senior executives. If they feel the need to upgrade to Business or First Class, they must do so from their own pocket. And instead of buying hardware from an OEM vendor, AWS sources its own components – everything from processors to disk drives to memory and network cards — and uses contract manufacturing to put together its machines."
