szczys writes "Gregory Charvat has been playing with and teaching others about entry-level radar concepts for a long time. Now he's sat down and explained how you can do it yourself inexpensively. He says, 'One enabling technology for Radar was the cathode ray tube (CRT), which facilitated a method of measuring the time delay between transmitted and received waveforms. ... Today, rather than using a CRT we can use high-speed digitizers. This offers the obvious advantage of applying signal processing to acquired data so that only moving targets are detected, tracking can be achieved, imaging, and a multitude of other modes. But for hobbyist and consumer projects we do not need this much power, range, and can not afford the cost. We need the ability to sense like a long range radar (detecting only moving targets, imaging, Doppler, signatures, etc) but at short ranges and at low costs.' Charvat then proceeds to walk through several options for the amatuer hardware hacker."

Rambo Tribble writes "Reuters reports Google has initiated lobbying efforts to stymie attempts by some states to enact distracted driver laws aimed at wearable technologies, such as Google Glass. 'Google's main point to legislators is that regulation would be premature because Google Glass is not yet widely available, the state elected officials say. Illinois state Senator Ira Silverstein, a Chicago Democrat who introduced a Google Glass restriction bill in December, responded that it was clear the merchandise was heading for the broader public.' Given the toll on our highways shown to arise from distracted drivers, is this responsible corporate behavior to protect their product, or an unethical endangering of lives?"

coondoggie writes "Few things can mess up a highly technical system and threaten lives like a counterfeit electronic component, yet the use of such bogus gear is said to be widespread. A new Defense Advanced Research Projects Agency (DARPA) program will target these phony products and develop a tool to 'verify, without disrupting or harming the system, the trustworthiness of a protected electronic component.'"

pacopico writes "About 24 years ago, a tiny chip company came to life in a Cambridge, England barn. It was called ARM, and it looked quite unlike any other chip company that had come before it. Businessweek has just published something of an oral history on the weird things that took place to let ARM end up dominating the mobile revolution and rivaling Coke and McDonald's as the most prolific consumer product company on the planet. The story also looks at what ARM's new CEO needs to do not to mess things up."

malachiorion writes "Have you heard the one about the Christian college in North Carolina that bought a humanoid robot, to figure out whether or not bots are going to charm us into damnation (dimming or cutting our spiritual connection to God)? The robot itself is pretty boring, but the reasoning behind its purchase—a religious twist on the standard robo-phobia—is fascinating. From the article: '“When the time comes for including or incorporating humanoid robots into society, the prospect of a knee-jerk kind of reaction from the religious community is fairly likely, unless there’s some dialogue that starts happening, and we start examining the issue more closely,” says Kevin Staley, an associate professor of theology at SES. Staley pushed for the purchase of the bot, and plans to use it for courses at the college, as well as in presentations around the country. The specific reaction Staley is worried about is a more extreme version of the standard, secular creep factor associated with many robots. “From a religious perspective, it could be more along the lines of seeing human beings as made in God’s image,” says Staley. “And now that we’re relating to a humanoid robot, possibly perceiving it as evil, because of its attempt to mimic something that ought not to be mimicked.”'"

The seafloor carpet, a system inspired by the wave absorbing abilities of a muddy seabed, has taken exploring the potential of wave power to some intriguing new depths."

An anonymous reader writes "There is a very interesting project underway to recreate the ZX Spectrum and more. The Bluetooth ZX Spectrum has been successfully crowdfunded, and it is due to go on sale in September 2014. If you want to go back to the 1980s — to the wonderful era of 8-bit gaming, you can instead try one of the many ZX Spectrum emulators." I remember being excited at the new Sinclair when my dad brought it home, but my strongest memory now is of what might be the worst keyboard I've ever had the chance to use.

sfcrazy writes "Amazon is all set to get Apple and Roku some serious competition with its own 'web-TV' or set-top box. According to reports, Amazon will be using Google's Android to build the box. Amazon already has a huge library of content (from Amazon Prime) which it can push to the living room through the box. Amazon, like Netflix, is also investing heavily in producing content to their own set-box. Amazon has also been hiring game developers and it won't be surprising if the company also dabbles into gaming." And while it may be only a rumor, the idea's got some reasonable legs: besides the content on Prime, Amazon has been making media-centric Android devices for a few years with its Kindle Fire line.

Zothecula writes "Three years ago, we heard about a prototype shoe that could be used to guide the wearer via haptic feedback. Designed by Anirudh Sharma, who was then a researcher at Hewlett-Packard Labs in Bangalore, India, the Lechal shoe was intended for use mainly by the blind. This week, however, Sharma and business partner Krispian Lawrence announced that the production version of the Lechal will soon be available for preorder, and it's aimed at helping all people navigate the city streets." Sensor-laden shoe computers aren't a new idea; in the past, they've just been put to different purposes (PDF).

AmiMoJo writes "The operator of the Fukushima Daiichi plant has been developing countermeasures to deal with repeated leaks from tanks of contaminated water. But despite the measures, 100 tons of radioactive water leaked on Wednesday and Thursday. 'The leaked water was among the most severely contaminated that Tepco has reported in the aftermath of the March 2011 disaster at the Fukushima Daiichi plant, when damage caused by an earthquake and a tsunami led to meltdowns in three of the plant’s reactors. Each liter of the water contained, on average, 230 million becquerels of particles giving off beta radiation, the company said. About half of the particles were likely to be strontium 90, which is readily taken up by the human body in the same way that calcium is, and can cause bone cancer and leukemia.' The estimated volume of the leaked radioactive materials caused Japan's nuclear regulator to rank the leak a level-3 serious accident. The international scale of nuclear and radiological events ranges from zero to 7."

lunatick writes "I put in my application for Google Glass as a joke. I never figured I would be selected. Well in less than one week I got my invite to buy Google Glass. My main hold back is the $1500 price tag for a device that just seems to be a camera and navigation aid. Does anyone in the /. community have Google Glass and can they give some advice to the rest of us considering it?"

Hugh Pickens DOT Com writes "Gary Marshall writes that.Microsoft's marvelous motion-sensing device is doing really good work for Sony, helping the PS4 outsell the Xbox One in the US and rocketing it to the top of the world's console sales charts. With the Xbox One $100 more expensive than the PlayStation 4, the Kinect is the explanation for the huge difference in price between the rival platforms says Marshall. "That kind of money makes a huge difference, and I wonder: if Microsoft had kept the Kinect as an optional add-on, which we all know it should be, would the Xbox One be much more attractive?" Ben Kuchera describes the peripheral as one of the most hated pieces of equipment in current use. "The system is still new, but every Xbox One owner now has a peripheral that has little reason to exist, aids their gaming in very few real ways and costs them a significant amount of money." The common defense of the Kinect is that developers wouldn't support it unless it was forced on consumers but according to Kuchera pushing a product on the public with the hope that it will be useful once we have it is a cruel inversion of how product adoption should be handled. "The forced pack-in proves something we already knew at the beginning of this generation: Almost no one would want to buy the Kinect separately if they were given the choice," writes Kuchera. "It's time to make the Kinect a peripheral, not a pack-in.""

Nerval's Lobster writes "The remote-access management flaw that allowed TheMoon worm to thrive on Linksys routers is far from the only vulnerability in that particular brand of hardware, though it might be simpler to call all home-based wireless routers gaping holes of insecurity than to list all the flaws in those of just one vendor. An even longer list of Linksys (and Cisco and Netgear) routers were identified in January as having a backdoor built into the original versions of their firmware in 2005 and never taken out. Serious as those flaws are, they don't compare to the list of vulnerabilities resulting from an impossibly complex mesh of sophisticated network services that make nearly every router aimed at homes or small offices an easy target for attack, according to network-security penetration- and testing services. For example, wireless routers (especially home routers owned by technically challenged consumers) are riddled with security holes stemming from design goals that emphasize usability over security, which often puts consumers at risk from malware or attacks on devices they don't know how to monitor, but through which flow all their personal and financial information via links to online banking, entertainment, credit cards and even direct connections to their work networks, according to a condemnation of the Home Network Administration Protocol from Tenable Network Security. Meanwhile, a January 2013 study from Rapid7 found 40 million to 50 million network-enabled devices, including nearly all home routers, were vulnerable to exploits using UPnP. Is there any way to fix this target-rich environment?" If only there were an easily upgradeable open source router operating system to which vendors could add support for their hardware leaving long term maintenance to a larger community.

MTorrice writes "By shaving off an ultrathin layer from the top of a silicon wafer, researchers have transformed rigid electronic devices into flexible ones. The shaving process could be used to fabricate parts for wearable electronics or displays that can roll up. Compared to similar techniques to make bendable silicon electronics, the new method is more cost-effective and produces more flexible devices, its developers say."

An anonymous reader writes "As our cars have become more complex, so have the user interfaces with which we control them. Using the current crop of infotainment systems embedded in a car's dash is byzantine and frustrating. UI designer Matthaeus Krenn has put up a post demonstrating his efforts to reinvent in-car UIs in a way that doesn't force people to squint at tiny buttons, instead leaving more of their attention for the road. It's based on using a touch-screen display that realigns the interface to wherever you put your fingers down. It also reacts differently depending on how many fingers you use to touch the screen."

Vigile writes "NVIDIA is launching the GeForce GTX 750 Ti today, which would normally just be a passing mention for a new $150 mainstream graphics card. But company is using this as the starting point for its Maxwell architecture, which is actually pretty interesting. With a new GPU design that reorganizes the compute structure into smaller blocks, Maxwell is able to provide 66% more CUDA cores with a die size that is just 25% bigger than the previous generation all while continuing to use the same 28nm process technology we have today. Power and area efficiency were the target design points for Maxwell as it will eventually be integrated into NVIDIA's Tegra line, too. As a result the GeForce GTX 750 Ti is able to outperform AMD's Radeon R7 260X by 5-10% while using 35 watts less power at the same time."

Paul server guy writes "I am building a limousine bus, and the owners want to prevent occupants from using cameras on board. (But they would like the cameras mounted on the bus to continue to operate; I think they would consider this optional.) They would also like to do it without having to wear any 'anti-paparazzi' clothing (because they also want to protect the other guests on board), and without destroying the cameras. (So no EMP generators, please). We've done some testing with high-power IR, but that proved ineffective. Does anyone have any ideas that they are willing to share?"

An anonymous reader writes "Shubham Banerjee, a seventh grader in California, has developed a braille printer made from a $350 Lego Mindstorms EV3 kit and some simple hardware. He calls the science fair project the Braigo. 'The Braigo's controller is set up to scroll through the alphabet. You choose a letter and it prints it out with tactile bumps on a roll of calculator paper. The print head is actually a thumbtack, which Banerjee settled on after also testing a small drill bit and a mechanical pencil. The first prototype isn't terribly fast, but it proves the concept works. Banerjee is working on improvements that will allow it to print full pages of text.'"
