The U.S. Army’s Mobile Digital Fabrication Lab

Politically speaking, the war in Afghanistan may be winding down; but technologically speaking, things are ramping up. Earlier this month a shipping container was quietly deployed to a remote outpost in Afghanistan. Kitted out by the U.S. Army’s Rapid Equipping Force, this particular shipping container is essentially a digital manufacturing lab in a box. Known as the ELM or Expeditionary Lab – Mobile, the unit contains a 3D printer and a CNC mill (as well as more conventional tools like a plasma cutter, welding gear, a circular saw, a router, a jigsaw and a reciprocating saw). Unsurprisingly, troops on the ground are not using the ELMs to print out heart-shaped gears ; rather, the point of the ELMs is to allow last-minute rapid prototyping upgrades to crucial pieces of equipment. As one example, soldiers discovered that the on-button for one standard-issue tactical flashlight had a raised button that could accidentally be pressed, unintentionally turning the flashlight on while the soldier was moving around. Best case scenario, the thing’s in a pocket, you don’t realize it’s on and the batteries drain down. Worst case scenario, the sudden illumination advertises your position to the enemy while you’re sneaking around in the dark. Under normal Army procurement procedures, designing, commissioning, manufacturing and distributing an updated design would take months or years. But with the ELMs, which come with two digital manufacturing technicians, a solution like this clip-on guard to shield the button can be quickly designed and printed. The ELM shipped earlier this month was actually the second; the first was sent to Afghanistan last summer. Following the concept’s success, a third ELM is in the works and will reportedly be deployed later this year. The following video on the ELMs isn’t terribly detailed, and features CG footage that doesn’t quite track with the narrative, but it’s all we’ve got: via 3ders (more…)

This interactive travel map of the Roman Empire is like Oregon Trail meets Civilization

Ever wondered how long it would take to travel from Rome to Constantinople at the peak of the Roman Empire? Or from Luna to Larissa? Or Parma to Thessalonica? This map of the Roman World created at Stanford University is awesomely realistic — all the ancient transportation lines on it actually existed 2,000 years ago. More »

Researchers create two different kinds of lava lamp… for science!

Okay, technically this isn’t a lava lamp, but you could have fooled me, given the mellow music and the drifting plumes of colored liquid. Researchers at Cambridge performed an experiment to find out more about fluid dynamics by coming up with two completely different ways that liquids can mix due to Rayleigh-Taylor instability, along with a video to watch if/when you’re stoned.

Time Warner: Netflix Is Unfairly Withholding High-Quality Content

Netflix is currently rolling out infrastructure to pump 3D and higher-quality HD content through the pipes to your home. But Time Warner is upset : it thinks that Netflix’s plan to only offer the new conent to ISPs that participate in its Open Connect initiative is unfair on consumers. More »

An astonishing shampoo-related physics mystery

In the 1960s, when some were exploring the mysteries of outer space and quantum mechanics, one engineer noticed an extraordinary unexplained phenomenon in shampoo. The sudden, energetic, and seemingly spontaneous bursts of liquid that seemed to randomly squirt out from ordinary shampoo were a mystery for forty years. Here’s why your shampoo, while being poured, sometimes leaps up and tries to get you. More »

FCC adds spectrum to Wi-Fi—but you likely need a new router to use it

Jason Alley The Federal Communications Commission last week said it will add 195MHz of spectrum to Wi-Fi’s 5GHz band. This move is designed to relieve congestion in Wi-Fi networks, particularly in areas of widespread simultaneous usage like airports and sports stadiums . It could help your home network too, but not right away—routers available in stores today may not be able to use the new spectrum at all . Finding out definitively whether today’s routers will support the new spectrum is difficult, partly because the FCC still has to issue specific rules governing its use. We’ve hit up router vendors and other industry people to find out whether software updates might let current routers access the new spectrum. While the results were a bit muddled, it seems safe to say no one is guaranteeing today’s routers will get the benefit of the new 195MHz. Even the latest routers supporting the ultra-modern 802.11ac standard may be left behind. Cisco refused to comment at all, telling us only “Cisco has not made any announcements about this so cannot discuss at this time.” Buffalo told us “the chip vendors will need to work on it” and that “they will at least to have to make changes to the hardware driver. … The magnitude of that change will determine if Buffalo is able to use the same hardware.” Read 21 remaining paragraphs | Comments

Facebook’s Open Compute Project splits up monolithic servers with help from Intel, more

As much as it’s important to have every component of a PC stuck together in a laptop, that same monolithic strategy is a major liability for server clusters: if one part breaks or grows obsolete, it can drag down everything else. Facebook and its Open Compute Project partners have just unveiled plans to loosen things up at the datacenter. A prototype, Atom -based rackmount server from Quanta Computer uses 100Gbps silicon photonics from Intel to connect parts at full speed, anywhere on the rack. Facebook has also garnered support for a new system-on-chip connection standard, rather affectionately named Group Hug, that would let owners swap in new mini systems from any vendor through PCI Express cards. The combined effect doesn’t just simplify repairs and upgrades — it lets companies build the exact servers they need without having to scrap other crucial elements in the process. There’s no definite timeframe for when we’ll see modular servers put to work, but the hope is that a cluster’s foundations will stay relevant for years instead of months.

AT&T now offering FaceTime over Cellular on all tiered data plans

It’s been a slow process, but AT&T is gradually making FaceTime over Cellular (Apple’s video chat service) available to more people. The feature was introduced with iOS 6, but it was up to carriers on how they wanted to implement the service — if at all. AT&T chose to offer it to only shared data customers at first, to ensure that the carrier’s network could handle the additional load. Finally, the top GSM operator in the US has announced that it will now allow the feature on all tiered data plans, and it should be rolling out to customers over the course of the next two weeks. There’s still no word on grandfathered unlimited plans, but don’t get your hopes up on that happening any time soon. To get the full explanation, head to the source link below.
