Video Saurabh Narain and His Homemade Lego-Based Rubik's Cube Solver (Video) 43

Here's another one Tim spotted at Maker Faire Bay Area 2014: A Rubik's Cube solver made by 12-year-old Saurabh Narain. He's in 7th grade -- and started soldering in 2nd grade and messing with Linux in 3rd grade. "What do you want to be when you grow up?" Tim asked. "An engineer..." (not that you couldn't have guessed). There may be faster Rubik's Cube solvers, and there may be slicker-looking ones, but Saurabh's is a lot more elegant, if you define engineering elegance as getting the most accomplished with the fewest possible parts, using the simplest possible design. And both of the fancier Rubik's Cuber solvers linked to in this paragraph were made by adult engineers, while Saurabh is 12. Can you imagine what he'll be like at 18? Or 28? Not that he's alone; there are lots of other engineering prodigies out there. The next 10 or 20 years are going to be amazing if we encourage young people to go into STEM, and even 5% of them are as smart as Saurabh. (Alternate Video Link)

European iPhone Chargers Prone To Overheating 128

jones_supa sends word that Apple has launched an exchange program for European iPhone USB power adapters. The company says its A1300 adapters were bundled with the iPhone 3GS, iPhone 4, and iPhone 4S models, and were also sold on their own from Oct. 2009 to Sept. 2012. The reason for the recall is that the adapters "may overheat and pose a safety risk." No further details are provided (a YouTube video shows a teardown of the device).

Samsung Debuts Thin Galaxy Tab S With Super AMOLED 2560X1600 Display 176

MojoKid (1002251) writes Samsung unveiled its latest flagship tablet, the Galaxy Tab S, at an event in New York City tonight, and the new device is thin, lightweight, and sports a killer Super AMOLED display. Samsung boasts that the Galaxy Tab S's 2560x1600 display has 73% better color reproduction than conventional LCD displays and can match colors up to 94% of "nature's true palette" with deeper blacks and a 100,000:1 contrast ratio. The 10.5-inch device weighs just 467g and measures a mere 6.6mm in thickness (and there's an 8.4-inch version, too). Under the hood, the Galaxy Tab S features Android KitKat 4.4, 3GB of RAM, 16GB or 32GB of storage with a microSD slot that supports up to 128GB. The front camera is 2.1MP and the rear 8MP camera has an LED flash. No word on the exact processor on board just yet, other than it's a quad-core SoC. It's likely a Qualcomm Snapdragon 801 though an Exynos variant or perhaps even Tegra 4 wouldn't be beyond the realm of possibility.

Open-Source Hardware For Neuroscience 41

the_newsbeagle (2532562) writes "The equipment that neuroscientists use to record brain signals is plenty expensive, with a single system costing upward of $60,000. But it turns out that it's not too complicated to build your own, for the cost of about $3000. Two MIT grad students figured out how to do just that, and are distributing both manufactured systems and their designs through their website, Open Ephys. Their goal is to launch an open-source hardware movement in neuroscience, so researchers can spend less time worrying about the gear they need and more time doing experiments."

Starbuck's Wireless Charging Stations Won't Work With Most Devices 114

Lucas123 (935744) writes Starbucks today announced that after beta-testing wireless charging in several locations, it will roll it out to all of its cafes in the U.S. Unfortunately, the Powermat wireless chargers they chose to use doesn't support the overwhelming number of mobile devices that are enabled for wireless charging using the Qi standard. Of the 20 million consumer devices estimated to have shipped in 2013 with wireless charging capabilities, nearly all were built with the Qi specification, according to IHS. The majority of the Qi technology was built into devices such as the Google Nexus 4 and 5 smartphones, Google's Nexus 7 second-generation tablet and a number of models in Nokia's Lumia smart phone range. The battle between the three wireless charging consortiums is expected to continue to adversely impact adoption of the technology.

Video John Hawley and His Dr. Who-Inspired Robot K-9 (Video) 23

By day John Hawley is a mild-mannered open hardware evangelist for Intel. But after hours he is the master of K-9, a robot dog he works on a little at a time. Yes, this is a Whovian thing, which is why John's K-9 looks so much like the Doctor's. But K-9 is also a pretty good dog on his/her own. No vet bills, no constant hunger, no barking at feral cats in the middle of the night, obeys every command... so maybe Dr. Who and John Hawley have the right idea when it comes to canines. Except.... aww.... my dog, Terri the Terrorist Terrier, just licked my hand. What a sweetie! Terri may not take orders from a hand-held remote, but she has a lot of other fine characteristics, including affection. K-9 is very cute in a squared-off, mechanical way, though. Hard to resist, despite a lack of soft fur and no tongue for licking his/her master's hand. (Alternate Video Link)

Ask Slashdot: PC-Based Oscilloscopes On a Microbudget? 172

New submitter fffdddooo (3692429) writes I know it's something that people used to ask every few years, but answers get old so quickly. I'm an electronics teacher, and I'm wondering if it's possible to find some oscilloscope (and why not spectrum analyser?) for recommending to my students, to be able to work at home. I'm thinking of something near $50-$70. Two or three years ago, I'm sure the answer was No, but nowadays? The same reader points out two options spotted on Amazon: one that's "very cheap but Khz" (it's also a kit that requires assembly), and another that aims to be capable of 20MHz, 2-channel operation. What's out there, he'd like to know, that's not junk?

Cisco Spending Millions of Dollars Secretly Purchasing New Juniper Products 120

FrankPoole (1736680) writes According to a CRN investigative report, Cisco has been spending millions of dollars over several years to secretly purchase Juniper Networks' products, including new QFabric and MX series routers, for use in its 'competitive analysis lab,' where the products are tested and reverse engineered. According to the report, some of the Juniper products purchased by Cisco were still in beta and not yet commercially released. In addition, CRN discovered that a main source for Cisco to obtain these Juniper products was, ironically, a company called Torrey Point Group, a fast-growing VAR that was awarded Juniper's Part of the Year in 2011.

Bloomberg Testing Productivity App For Oculus Rift 38

Nerval's Lobster writes: So far, the Oculus Rift virtual-reality headset has found its most widespread use in gaming. But as the device rises in prominence, more companies are testing its capabilities as a work tool. Bloomberg is one of those companies, having designed software that allows Oculus-equipped traders and financial pros to view dozens of virtual "screens," each one packed with data. The platform is clearly aimed at those Masters of the Universe who stack their real-world desks with four, six or eight screens—the better to take the pulse of the markets. Think of it as a traditional Bloomberg terminal on steroids. "This is a mockup of how virtual reality can be applied in the workplace," Nick Peck, a Bloomberg employee responsible for creating the software, told Quartz. "I really wanted to explore how virtual reality could solve one of the most basic problems we hear about: limited screen real estate." A virtual-reality Bloomberg terminal isn't the only practical application proposed by Oculus Rift users: earlier this year, the Norwegian Armed Services began testing whether the hardware could be used to drive tanks, on the supposition that off-the-shelf cameras and a headset built for virtual gaming could prove cheaper than custom-built military equipment.

Ellipto: a DIY Fitness Tracker and Dashboard In 70 Lines 32

New submitter InternetOfJim writes: "This is one of the most fun weekend projects I've done in a while — a fitness tracker for my elliptical trainer. But the real agenda was to figure out how lazy I could be via web services (Keen IO and Brace IO) and development platforms (Electric Imp). Quite lazy, as it turns out. I wound up with a working device and a nice realtime dashboard with no soldering, no backend to manage, and surprisingly little original code needed beyond the sensing and power conserving parts of the firmware and a little javascript to customize the dashboard."

Killing Zombies In VR With the Latest Version of Project Holodeck At E3 2014 23

muterobert (2927951) writes with an update on the full immersion VR system from Project Holodeck (now renamed Survios). The system combines an Oculus DK2 with external sensors to make a fully immersive 8x'8' space "Ben Lang from Road to VR goes hands on and heads in with virtual reality technology company Survios' newest version of untethered VR system 'Prime 3'. He moves around the virtual space, holding and reloading weapons as you would in real life. 'At one point while playing, I was wielding the shotgun with two hands, with the table of weapons was on my right side. Several zombies were approaching and I needed a bit more fire power. I dropped the shotgun, reached over with my right hand to grab the tommy gun off the table, then virtually tossed it from my right hand to my left hand (because I'm a lefty), then pulled my pistol out of the holster with my right hand and continued to shoot both weapons.'" The article has a video, and it almost makes me think it's what being in the metaverse would be like.

$3000 GeForce GTX TITAN Z Tested, Less Performance Than $1500 R9 295X2 151

Vigile writes: NVIDIA announced its latest dual-GPU flagship card, the GeForce GTX Titan Z, at the GPU Technology Conference in late March with a staggering price point of $2999. Since that time, AMD announced and released the Radeon R9 295X2, its own dual-GPU card with a price tag of $1499. PC Perspective finally put the GTX Titan Z to the test and found that from a PC gamer's view, the card is way overpriced for the performance it offers. At both 2560x1440 and 3840x2160 (4K), the R9 295X2 offered higher and more consistent frame rates, sometimes by as much as 30%. The AMD card also only takes up two slots (though it does have a water cooling radiator to worry about) while the NVIDIA GTX Titan Z is a three-slot design. The Titan Z is quieter and uses much less power, but gamers considering a $1500 or $3000 graphics card selection are likely not overly concerned with power efficiency.

Video Security DVR + iNet + X10 = Easy Home Automation (Video) 25

25-year electronics veteran Conrad Lee noticed that commodity multi-channel security DVRs have both more channels than a typical household needs and more capabilities than their makers advertise -- at least, with some creative re-use of their video feeds. With a home-grown controller hooked up to an otherwise unused video channel, a run of the mill security DVR can be used as a command center for household items, like lights, locks, thermostats, cameras, or whatever else you think of) by means of controls both old-fashioned (the ubiquitous X10 devices, some of which you probably have stashed in a drawer) and new (Z-wave). He showed off his system at last month's Maker Faire -- take a look (video below) at what his clever hardware re-use makes possible, and at Lee's controller. It means giving up one (relatively) inexpensive channel, to gain capabilities that would cost quite a bit more in a ready-built system, like smart-phone control and pan/tilt control for cameras.

Fuel Cells From Nanomaterials Made From Human Urine 83

New submitter turning in circles (2882659) writes 'Carbon based fuel cells require carbon doped with other elements, normally platinum, for oxygen reduction reactions. Urine contains carbon with an exciting splash of nitrogen, sulfur, potassium, silicon, and so on, and you don't have to manufacture it: the stuff just comes out by itself. In an article published this week in an open journal, researchers from Korea reported a new nanomaterial for fuel cells, which they dub "Urine Carbon." Upon drying, and then heating at 1000C, and rinsing of salts, the resulting Urine Carbon porous nanostructures outperformed Carbon/platinum in electrodes.'

$470 RepRap Derived 3D Printer Going Into Production 32

An anonymous reader writes "South African makerstore OpenHardware.co.za has designed and built a new RepRap-derivative 3D printer which it plans to sell for less than R5000 ($470). The first completed units are being put together now, with an eye to shipping late June. Store owner Peter van der Walt says that he designed Babybot — which has a print area equivalent to a RepRap Prusa Mendel-style machine — in order to reduce build and support costs. He's been selling various RepRap designs in kit form for two years, but as they become more popular is struggling to keep up with demand and handle returns. By sourcing more materials locally — he also designs his own controller boards — he's looking to beat the likes of RS Components and large shopping chains which have begun shipping the likes of Cubify in the country."

Video Hack A Day Prize is a Trip To Space (Video) 34

Last month, at Maker Faire Bay Area 2014, Timothy Lord spotted a guy wearing a very large piece of headgear that included two crossed wrenches. The guy turned out to be Mike Szczys, Managing Editor of hackaday.com, which says, "The Hackaday Prize will send one person into space for building the next evolution of hardware." That's certainly of interest to the hardware hacker/maker crowd. How they're going to arrange the space flight (probably one of those "just above the atmosphere" hops) isn't specified, but even so the contest is an interesting idea, and the Hack A Day site seems to have some interest hacks and tutorials on it. So go ahead and enter the contest -- and don't forget to take your camera with you on your flight into space, because we'll want to see pictures! (Alternate Video Link)
