Using Mech Combat To Hone Engineering Skills 59

Posted by Soulskill from the and-practicing-for-defeating-skynet dept.
jjp9999 writes "Mech Warfare is a mix between Battlebots and MechWarrior, only without the fanfare. The teams around the competitions include engineers and professionals in robotics, and the games are — aside from being an homage to their love for science fiction — a way to hone their skills in the field. Andrew Alter, roboticist and one of the mech pilots, said the competitions are taken as 'an engineering challenge,' noting that while they do compete, 'Having this mix of skill levels and demographics is really great to see, as information and ideas tend to flow freely. We're also solving practical real-world problems like being able to stream video over Wi-Fi in high-interference areas. It's not nearly as easy as one might think.'"

Optimize Offshore Wind Farms Using Weather Modeling 111

Posted by Soulskill from the any-way-the-wind-blows dept.
An anonymous reader sends this excerpt from a Stanford news release: "Politics aside, most energy experts agree that cheap, clean, renewable wind energy holds great potential to help the world satisfy energy needs while reducing harmful greenhouse gases. Wind farms placed offshore could play a large role in meeting such challenges, and yet no offshore wind farms exist today in the United States. In a study just published in Geophysical Research Letters, a team of engineers at Stanford has harnessed a sophisticated weather model to recommend optimal placement of four interconnected wind farms off the coast of the Eastern United States, a region that accounts for 34 percent of the nation’s electrical demand and 35 percent of carbon dioxide emissions. ... Among its findings, the Stanford model recommended a farm in Nantucket Sound, precisely where the controversial Cape Wind farm has been proposed. The Cape Wind site is contentious because, opponents say, the tall turbines would diminish Nantucket’s considerable visual appeal. By that same token, the meteorological model puts two sites on Georges Bank, a shallows located a hundred miles offshore, far from view in an area once better known for its prodigious quantities of cod. The fourth site is off central Long Island."

A Hacked WiFi Router, an API, and a Toy Bus: It's the Ambient Bus Arrival Monito 53

Posted by Soulskill from the don't-want-to-be-outdoors-any-longer-than-necessary dept.
JohnGrahamCumming writes "In this simple project, a hacked Linksys WRT54GL talks to a public API to get real-time bus information, and displays the times of the next buses on a model bus. Never miss the bus again! 'It's possible to reflash the Linksys with a custom Linux installation that lets me control the box completely (and still use it as a wireless router). There are various project, but I used OpenWRT. With OpenWRT it's possible to SSH into the box and treat it as any Linux server (albeit a rather slow one). But there's plenty of power to grab bus times and update an LED display connected to the WRT54GL's serial port. "

Is It Time For the US Government To Back Fusion At NIF Over ITER? 308

Posted by Soulskill from the come-on-now,-you're-both-pretty dept.
ananyo writes "Laser beams at the National Ignition Facility have fired a record 1.875 megajoule shot into its target chamber, surpassing their design specification. The achievement is a milepost on the way to ignition — the 'break-even' point at which the facility will finally be able to release more energy than goes into the laser shot by imploding a target pellet of hydrogen isotopes. NIF's managers think the end of their two-year campaign for break-even energy is in sight and say they should achieve ignition before the end of 2012. However, with scientists at NIF saying that a $4 billion pilot plant could be putting hundreds of megawatts into the grid by the early 2020s, some question whether the Department of Energy is backing the wrong horse with ITER — a $21-billion international fusion experiment under construction at St-Paul-lez-Durance, France. Is it time for the DoE to switch priorities and back NIF's proposals?" Perhaps a better idea, given the potential benefits of fusion research, would be for the DoE to throw their weight behind multiple projects, rather than sacrificing some to support others.

Seagate Hits 1 Terabit Per Square Inch 224

Posted by timothy from the please-take-a-minute-to-wonder dept.
MrSeb was one of several readers to submit news that drive manufacturer Seagate has announced (and demoed) the first hard drive to squeeze a terabit into each square inch of platter. "'Initially this will result in 6TB 3.5-inch desktop drives and 2TB 2.5-inch laptop drives, but eventually Seagate is promising up to 60TB and 20TB respectively. To achieve such a huge leap in density, Seagate had to use a technology called heat-assisted magnetic recording (HAMR). Basically, the main issue that governs hard drive density is the size of each magnetic 'bit.' These can only be made so small until the magnetism of nearby bits affects them. With HAMR, 'high density' magnetic compounds that can withstand further miniaturization are used. The only problem is that these materials, such as iron platinum alloy, are more stubborn when it comes to writing data — but if you heat it first, that problem goes away. With HAMR, Seagate has strapped a laser to the hard drive head; when it wants to write data, the laser turns on. Reading data is still done conventionally, without the laser. In theory, HAMR should allow for areal densities up to 10 terabits per square inch (magnetic sites that are just 1nm long!), and thus desktop hard drives in the 60TB range."

iFixit's Kyle Wiens On the War On DIY Electronics 760

Posted by Unknown Lamer from the insert-car-analogy-here dept.
pigrabbitbear writes with an excerpt from an article at Motherboard: "Anyone planning on buying a new iPad should know what they're getting themselves into by now. In recent years, Apple and other hardware manufacturers have made it liquid-crystal clear that they're not fond of the idea that customers can tear open and fix products without the help of licensed repair specialists. Even if it's as easy as ordering a part online and following a few instructions gleaned from a Google search, hardware companies generally seem to prefer we keep the hood closed. It should not be surprising, then, that the latest version of Apple's much-desired tablet has one 'killer' feature that's finally getting the attention it deserves: A design that stops you from getting inside of it."

A Look At One of Blizzard's Retired World of Warcraft Servers 116

Posted by Soulskill from the dissecting-a-nerd-playground dept.
MojoKid writes "At last count, Activision Blizzard pegged the number of World of Warcraft subscribers at 10.2 million. It takes a massive amount of gear to host all the different game worlds, or realms, as they're referred to. Each realm is hosted on its own server, and in late 2011, Activision Blizzard began auctioning off retired server blades from the days of yore to benefit the St. Jude Children's Research Hospital. They sold around 2,000 retired Hewlett-Packard p-Class server blades on eBay and donated 100 percent of the proceeds (minus auction expenses) to the St. Jude Children's Research Hospital, which seeks to advance the treatment and prevention of catastrophic diseases in children. This article has a look at one of those retired server blades."

Scientists Build Graphene From Scratch, Atom By Atom 185

Posted by Soulskill from the i-bet-that-goes-quick dept.
MrSeb writes "You've heard of 'designer babies,' the idea that you can customize a baby by altering its DNA, but now a team of researchers from Stanford University and the Department of Energy have meddled around with the very fabric of reality and created the very first 'designer electrons.' The bulk of the universe is made up from just a few dozen elements, and each of these elements is made up of just a few subatomic particles: electrons, protons, neutrons, quarks, and so on. For the most part, the properties of every material — its flexibility, strength, conductivity — is governed by the bonds between its constituent atoms, which in turn dictate a molecule's arrangement of electrons. In short, if you can manually move electrons around, you can create different or entirely new materials. That's exactly what Stanford University has done: Using a scanning tunneling microscope, the team of researchers placed individual carbon monoxide molecules on a clean sheet of copper to create 'molecular graphene' — an entirely new substance that definitely isn't graphene, but with electrons that act a lot like graphene (abstract). It is now possible, then, for scientists to create entirely new materials or tweak existing materials — like silicon or copper, or another important element — to make them stronger or more conductive. Where will this particular avenue lead us?"

'In some sense, for tablets the browser is a killer app. Maps is a killer app to some extent. Being able to share the screen with other people — that it's a social device — also might fit the bill. I think that for tablets, there isn't and won't be one killer app for everyone. It's more that there are apps that are killers for individual people. It's the sum of all those that is the killer app. This has been true since the original Palm Pilot.'"

The Laser Unprinter 168

Posted by samzenpus from the does-it-work-on-tattoos? dept.
MrSeb writes "You've heard of laser printers — and now a team of researchers from the University of Cambridge in England has created a laser unprinter that can remove ink without damaging the paper. Despite both methods using lasers, their (un)printing approaches are fundamentally very different. In a laser printer, a laser is used to give individual 'pixels' on a piece of paper a positive charge (a separate heat source is used to fuse toner). In the laser unprinter, picosecond pulses of green laser light are used to vaporize the toner, or ablate in scientific terms. The primary goal of unprinting is to cut down on the carbon footprint of the paper and printing industries. Manufacturing paper is incredibly messy business, with a huge carbon footprint. Recycling paper is a good step in the right direction, but it still pales in comparison to unprinting. In a worst-case scenario, The University of Cambridge unprinting method has half the carbon emissions of recycling; best-case, unprinting is almost 20 times as efficient."

China claims the embargoes are in place to protect its environment, while Obama denounces China as being unfair and not playing by the rules of the WTO. In 2009, the WTO released a report (PDF) that explained how actions like China's hurt trade partners."

Camera Gun Would Let Hunters Get Killer Wildlife Shots Screenshot-sm 263

Posted by samzenpus from the humane-hunter dept.
Zothecula writes "Not too long ago, brothers Randy and Michael Gregg were out on a hunting expedition. It was the day after deer season had ended, yet they spied a handsome animal bedded down in the snow. Not wanting to pass up an opportunity, they silently crept up on their quarry, raised their rifle, lined the deer up in the crosshairs ... and then took a picture through the scope with a mobile phone. That photo provided all the proof they needed that they had successfully stalked their prey, without bringing home an illegally-obtained carcass. It also inspired them to create the Kill Shot — a replica hunting rifle, that takes pictures instead of firing bullets." The Kill Shot isn't just for hunters. Think of how great this would be at sporting events or family reunions!

Cheap Solar Panels Made With An Ion Cannon 395

Posted by Soulskill from the fresh-from-the-daystrom-institute dept.
MrSeb writes "Twin Creeks, a solar power startup that emerged from hiding today, has developed a way of creating photovoltaic cells that are half the price of today's cheapest cells, and thus within reach of challenging the fossil fuel hegemony. As it stands, almost every solar panel is made by slicing a 200-micrometer-thick (0.2mm) wafer from a block of crystalline silicon. You then add some electrodes, cover it in protective glass, and leave it in a sunny area to generate electricity through the photovoltaic effect. There are two problems with this approach: Much in the same way that sawdust is produced when you slice wood, almost half of the silicon block is wasted when it's cut into 200-micrometer slices; and second, the panels would still function just as well if they were thinner than 200 micrometers, but silicon is brittle and prone to cracking if it's too thin. Using a hydrogen ion particle accelerator, Twin Creeks has managed to create very thin (20-micrometer), flexible photovoltaic cells that can be produced for just 40 cents per watt; around half the cost of conventional solar cells, and a price point that encroaches on standard, mostly-hydrocarbon-derived grid power."

Nanoscale Race Car Gets 3D Printed With a Laser 39

Posted by Soulskill from the bet-the-insurance-is-high-on-that-thing dept.
An anonymous reader writes "Researchers at the Vienna University of Technology have managed to perfect 3D printing at the nanoscale. What may look like a grain of sand to the human eye could in fact be a detailed racing car model, a reproduction of a famous church, or London Bridge. The 3D printer relies on a laser beam directed by mirrors through a liquid resin onto a surface. It can print at 5 meters per second, which is a world record, and the end result is only a few hundred nanometers in size. The next hurdle: printing with bio-material so we can start making our own body parts/organs."

MIT Fiber Points To Woven Glasses-Free 3D Displays 52

Posted by samzenpus from the surround-sight dept.
MrSeb writes "Electrical engineers and material scientists at MIT have created a fiber-borne laser that could be woven to form a flexible display that could project different 3D images in any number of directions, to any number of viewers. MIT's fiber is similar to standard telecoms fiber, but it has a tiny droplet of fluid embedded in the core. When laser light hits the fluid, it scatters, effectively creating a 360-degree laser beam. The core is then surrounded by layers of liquid crystal, which can be controlled like 'pixels,' allowing the laser light to escape from specific points anywhere along the length of the fiber. This means that you could have a display that shows one picture on the 'front' and another on the 'back' — or different, glasses-free 3D images for everyone sitting in front and behind. In the short term, the laser fiber is more likely to have a significant application in photodynamic therapy, an area of medicine where drugs are activated using light. Photodynamic therapy is one of the only ways to treat cancer in a relatively non-invasive and non-toxic manner. MIT's laser could be threaded into almost any part of the body, where the ability to produce pixels of laser light at any point along its length would make it a highly accurate device."
