An anonymous reader writes: To demonstrate how powerful modern computers are compared to their forebears, engineer Damian Peckett decided to approximate an Apple ][ with an Arduino Uno. In this post, he explains how he did it, from emulating the 6502 processor to reinventing how characters were displayed on the screen. "The Apple II used a novel approach for video generation, at the time most microcomputers used an interlaced frame buffer where adjacent rows were not stored sequentially in memory. This made it easier to generate interlaced video. The Apple II took this approach one step further, using an 8:1 interlacing scheme. This had the first line followed by the ninth line. This approach allowed Steve Wozniak to avoid read/write collisions with the video memory without additional circuitry. A very smart hack!" Peckett includes code implementations and circuit diagrams.

An anonymous reader writes: Stanford researchers have announced the creation of an aluminum-ion battery that they say will charge quicker, last longer, and be generally safer than common lithium-ion batteries. "Aluminum has long been an attractive material for batteries, mainly because of its low cost, low flammability and high-charge storage capacity. For decades, researchers have tried unsuccessfully to develop a commercially viable aluminum-ion battery. A key challenge has been finding materials capable of producing sufficient voltage after repeated cycles of charging and discharging. ... For the experimental battery, the Stanford team placed the aluminum anode and graphite cathode, along with an ionic liquid electrolyte, inside a flexible, polymer-coated pouch." The researchers' main challenges now are getting the battery to produce a higher voltage and store energy at a higher densities.

An anonymous reader writes LG accidentally revealed in blog post that Apple is planning to release a 8K iMac later this year. This news comes as a surprise as the leak came from a different company rather than Apple. LG is one of Apple's biggest display partners and has already demonstrated 8K monitors at CES in Las Vegas. They note that the panel boasts 16 times the number of pixels as a standard Full HD screen.

puddingebola writes Microsoft has announced it will no longer manufacture Kinect for Windows. Only the Xbox One version will be available for purchase. Microsoft said it could not meet demand for the device, a strange claim for a company to make. The console version, though, will still work with Windows by way of a USB adapter, and as pointed out by this similar story at Gamespot, for about the same total price.

An anonymous reader writes: Programmer Michael Fogleman recently built his own emulator for the original Nintendo Entertainment System. He's now put up a post sharing many technical insights he learned along the way. For example: "The NES used the MOS 6502 (at 1.79 MHz) as its CPU. The 6502 is an 8-bit microprocessor that was designed in 1975. ... The 6502 had no multiply or divide instructions. And, of course, no floating point. There was a BCD (Binary Coded Decimal) mode but this was disabled in the NES version of the chip—possibly due to patent concerns. The 6502 had a 256-byte stack with no overflow detection. The 6502 had 151 opcodes (of a possible 256). The remaining 105 values are illegal / undocumented opcodes. Many of them crash the processor. But some of them perform possibly useful results by coincidence. As such, many of these have been given names based on what they do." It's an interesting look at how software and hardware interacted back then, and what it takes to emulate that in modern times. Fogleman released the source code on GitHub.

An anonymous reader sends word that a busted MacBook Air and a Western Digital hard drive that once held Snowden revelations are going on display at the Victoria and Albert Museum in London. "The remains of computer hardware which had contained the Guardian's London trove of Snowden documents – and which was destroyed on the rather spiteful demands of GCHQ personnel – have gone on display at the Victoria and Albert Museum. While the frankly unremarkable remnants of a MacBook Air are uninteresting in and of themselves – who among us has not taken an angle grinder to an errant machine? – the causes of the MacBook Air's destruction are seemingly interesting enough to merit those remnants being considered art and subsequently included in V&A's new exhibition about 'the museum as a public space and the role of public institutions in contemporary life.' Disconcertingly titled All of This Belongs to You, the exhibition is to include 'three specially curated displays,' among which is Ways to be Secret, which will examine what the curators describe as 'the contradiction between our concern for online privacy and our obsession with sharing via social media.'"

Jay Maynard writes The OnLive gaming service that rose from the dead and became an inexpensive way to get high-end performance on low-end hardware has now been purchased by Sony Entertainment. Their games, desktop, and SLGo Second Life services will all end on April 30, 2015, and be free to use until then."

MojoKid writes Today, Intel took the wraps off new NVMe PCI Express Solid State Drives, which are the first products with these high speed interfaces, that the company has launched specifically for the enthusiast computing and workstation market. Historically, Intel's PCI Express-based offerings, like the SSD DC P3700 Series, have been targeted for datacenter or enterprise applications, with price tags to match. However, the Intel SSD 750 Series PCI Express SSD, though based on the same custom NVMe controller technology as the company's expensive P3700 drive, will drop in at less than a dollar per GiB, while offering performance almost on par with its enterprise-class sibling. Available in 400GB and 1.2TB capacities, the Intel SSD 750 is able to hit peak read and write bandwidth numbers of 2.4GB/sec and 1.2GB/sec, respectively. In the benchmarks, it takes many of the top PCIe SSD cards to task easily and at $389 for a 400GB model, you won't have to sell an organ to afford one.

NotRicky writes: The UK's terrible string of luck with violent robots continues. The man-shaped metal monstrosities that have plagued the country at seemingly random times throughout history rose up once more yesterday. No one yet knows their source, or what phenomenon — natural or man-made — keeps drawing them to that area of the world. While initial reports indicated trillions of dollars worth of damage and countless lives lost, the re-establishment of communications paints a much more hopeful picture. The British government remains quiet about the situation, politely refusing foreign aid and letting one of their intelligence agencies direct efforts to restore order. Reporters and camera crews are having difficulty documenting the situation — it's not clear whether this is due to interference from the government or simply the chaotic nature of the robot uprising. A medical professional on the scene was quoted as saying, "It's simple, really — even the flattened brick you call a computer can undelete, can't it?"

Lucas123 writes: While the rest of the nation's solar power generation hovers around 1%, California clocked in with a record 5% of power coming from utility-grade (1MW or more) solar power sources, according to a report from Mercom Capital Group and the Energy Information Administration. That's three times the next closest state, Arizona. At the same time, 22 states have yet to deploy even one utility-grade solar power plant, according to the Solar Energy Industry Association. Meanwhile, the rest of the world saw a 14% uptick in solar power installations in 2014 for a total of 54.5GW of capacity, and that figure is expected to grow even faster in 2015. While China still leads the world in new solar capacity, Japan and the U.S. come in as a close second and third, respectively. In the U.S. distributed solar and utility-grade solar installations are soaring as the solar investment tax credit (ITC) is set to expire next year. The U.S. is expected to deploy 8.5GW of new solar capacity in 2015, according to Mercom Capital Group.

An anonymous reader writes: Today Microsoft announced the latest device in their line of Windows tablets: the Surface 3. The tablet runs a full version of Windows (the troublesome "RT" line has been deprecated), and aims to compete with Apple's iPad. The Surface 3 has a 10.8" screen running at 1920x1280 (note the 3:2 ratio). It's 8.7mm thick and weighs 622 grams (1.27 lbs). They're somewhat vague about the battery life, but they say it will last up to 10 hours "based on video playback." They've also made it possible to charge the device with a standard micro-USB charger. The base device with 64GB storage, 2GB RAM, and Wi-Fi will cost $500, and it'll scale up with more storage, more ram, and 4G LTE connectivity. (It maxes out at 4GB RAM, so any heavy-duty gaming is probably out of the question.) The keyboard is still a separate $130 accessory as well.

wiredmikey writes: A massive power outage caused chaos and shut down public transport across Turkey on Tuesday, with the government refusing to rule out that the electricity system had been the victim of an attack. The nationwide power cut, the worst in 15 years, began shortly after 10:30 am (0730 GMT) in Istanbul, the state-run Anatolia news agency quoted the Turkey Electricity Transmission Company (TEIAS) as saying. Energy Minister Taner Yildiz said the authorities were investigating whether the power outage was due to a technical failure or cyber-attack. "It is too early to say now if it is because of a technical reason, a manipulation, a faultplay, an operational mistake, or a cyber (attack). We are looking into it... We cannot say they are excluded possibilities."

donniebaseball23 writes While the term 'Xbox' is firmly implanted in every gamer's mind today, when Microsoft first set out to launch a console in 2001, people weren't sure what to expect and Microsoft clearly wasn't sure what approach to take to the market. As Xbox co-creator Seamus Blackley explained, "In the early days of Xbox, especially before we had figured out how to get greenlit for the project as a pure game console, everybody and their brother who saw the new project starting tried to come in and say it should be free, say it should be forced to run Windows after some period of time." Blackley added that other ideas were pushed around at Microsoft too, like Microsoft should just gobble up Nintendo. "Just name it, name a bad idea and it was something we had to deal with," he said.

First time accepted submitter Legendary Teeth writes The makers of the Myo Gesture Control Armband (Thalmic Labs) have just released the specs for the Bluetooth protocol it uses. While there are already official SDKs for Windows, Mac, iOS and Android, this means that now anyone can roll their own support for other platforms like Linux or Arduino without needing to use one of the official platforms as a bridge. Anything you can write code for that that can act as a Bluetooth GATT client would now be possible, really. If you aren't familiar with the Myo armband, it's a Bluetooth Low Energy device with 8 EMG pods and an IMU that you wear on your arm. It can read your muscle activity to detect gestures you make with you hands, which you can then use to do things like fly drones, play games, or control music.

We started looking at ways to make instant hand-drawn or inkjet-printed circuit boards because Timothy met an engaging young man named Yuki Nishida at SXSW. Yuki is a co-founder of AgIC, a company that makes conductive ink pens and supplies special paper you can use to write or draw circuits or, if you have the right model of Brother printer, to print them with special inkjet inks. The AgIC people are aggressively putting the 'A' in STEAM by marketing their products to artists and craftspeople. Indeed the second line on their website's home page says, 'AgIC offers handy tools to light up your own art works.' This is an excellent niche, and now that AgIC has developed a circuit eraser (due to ship this April), it may lead to all kinds of creative designs. And as is typical with this kind of company these days, AgIC has been (at least partly) crowdfunded.

A little cursory Google searching will soon lead you to other companies selling into the home/prototype circuit board market, including Cartesian Co and their Argentum 3-D printer that does prototype and short-run PCBs and only costs $899 (on special at the time this was written) and Electroninks, which markets the Circuit Scribe pen and associated materials with an emphasis on education. There are others in this growing field, and a year from now there will probably be more of them, all working to replace the venerable breadboard the same way electronic calculators replaced slide rules.

malachiorion writes DARPA knows that people are afraid of robots. Even Steve Wozniak has joined the growing chorus of household names (Musk, Hawking, Gates) who are terrified of bots and AI. And the agency's response--a video contest for kids--is equal parts silly and insightful. It's called Robots4Us, and it asks high schoolers to describe their hopes for a robot-assisted future. Five winners will be flown to the DARPA Robotics Competition Finals this June, where they'll participate in a day-after discussion with experts in the field. But this isn't quite as useless as it sounds. As DRC program manager Gill Pratt points out, it's kids who will be impacted by the major changes to come, moreso than people his age.

Zothecula writes When firefighters need to enter smoke-filled buildings to conduct search or rescue, they frequently suffer from low visibility and often need to feel their way along walls or follow ropes reeled out by the lead firefighter. With a limited supply of oxygen carried by each firefighter, being slowed by the inability to see can severely limit their capacity to carry out duties in these environments. Now researchers from King's College London and Sheffield Hallam University have developed a prototype robot assistant for firefighters that can help guide them through even the thickest smoke.

knwny points out this lofty proposed power plan in China. "The battle to dispel smog, cut greenhouse gases and solve the energy crisis is moving to space. If news reports are to be believed, Chinese scientists are mulling the construction of a solar power station in a geosynchronous orbit 36,000 kilometres above ground. The electricity generated would be converted to microwaves or lasers and transmitted to a collector on Earth. If realized, it will surpass the scale of the Apollo project and the International Space Station and be the largest-ever space project."

An anonymous reader writes Ars is running a story about the new all-electric racing car series and its first visit to the U.S.. "The pit lane we're standing in is unusual, and not only because it's a temporary setup placed in the shadow of American Airlines Arena (home of the NBA's Miami Heat). Garages are set up on both sides rather than being limited to one. A few things also appear to be missing. To start, a familiar smell from the usual mix of burning hydrocarbons is absent. And it's remarkably quiet. The occasional impact wrench bursts out in a mechanical staccato, generators drone here and there, but there are no V8s burbling, no V6s screaming....Welcome to Formula E, the world's first fully electric racing series. Miami is playing host to the first of two US rounds—the next being held in Long Beach, CA, on April 4—and it's the fifth race in this ePrix's inaugural season. Given we've got a bit of a thing about racing at Cars Technica, as well as an obvious interest in electric vehicles, we had to be on the ground in Miami to experience this for ourselves."

tomhath writes with this story that may shake up the nuclear industry. "The biggest player in the beleaguered nuclear power industry wants a place alongside solar, wind and hydroelectric power collecting extra money for producing carbon-free electricity. Exelon Corp., operator of the largest fleet of U.S. nuclear plants, says it could have to close three of them if Illinois rejects the company's pitch to let it recoup more from consumers since the plants do not produce greenhouse gases. Exelon and other around-the-clock plants sometimes take losses when wind turbines produce too much electricity for the system. Under the system, electric suppliers would have to buy credits from carbon-free energy producers. Exelon says the plan would benefit nuclear plants, hydroelectric dams, and other solar and wind projects."
