V-Moda refines the sound design of last year's original Crossfade LP DJ headphones with a refresh that offers customized ear plates, dual 50mm drivers, and a tough backbone enforced under strict military testing.

For this version, V-Moda displays its newest Live Play sonic signature developed using a 31-band equalizer to ensure a clean space, free of artificial sound spikes. The guts are built around a driver diaphragm model with a hard inner ring that pumps mids and highs, while a softer outer ring on top extends the bass line for harder punches.

V-Moda takes precautions to protect the Crossfade LP2s so you don't have to. The headphones adhere to the military's MIL-STD-810G hardened guidelines and will likely outlive everything else in your DJ bag thanks to a Kevlar wrapped detachable cable, a headband that can bend completely flat, and the shell's resistance to humidity, salt spray, and UV exposure.

The company is also offering customers a chance to personalize their gear with a custom ear shield program that lets you select between 12 colors of interchangeable shields- if you ask nicely, V-Moda will even etch your artwork onto the sides, anything from your name, company, sports team logo, or personal artwork.

The V-Moda Crossfade LP2 headphones are available now for $199.

Are you a fan of first-person shooters? Check out this video of an astounding setup that immerses players in the action of Battlefield 3 unlike any other rig you've seen.

The gaming simulator, created by Channel 5's The Gadget Show, combines a jaw-dropping number of sensors and inputs for a highly realistic experience. The cost of the hardware alone was more than $650,000.… Read more

If you're behind on your reports and your boss is breathing down your neck, one of these might come in handy.

A British company lists this Martin Baker Mk6 ejector seat--which has been outfitted with a stainless steel frame so it can be used anywhere--as being for sale.

Once part of a Blackburn Buccaneer fighter jet, the seat still has its parachutes, harness, and eject levers. … Read more

Northrop Grumman's X-47B unmanned stealth plane achieved cruise mode flight for the first time recently, a major step toward using the bomber aboard aircraft carriers.

During a flight at Edwards Air Force Base on September 30, the robo-plane retracted its landing gear and flew in cruise configuration for the first time. The test helped prove its navigation hardware and software.

The flight was part of the X-47B's "envelope expansion" under the Navy's Unmanned Combat Air System Carrier Demonstration (UCAS-D) program. Northrop has produced two X-47Bs for the Navy and the aircraft is slated to begin carrier trials in 2013. … Read more

The drive for more fuel-efficient cars reaches beyond the garages of the U.S. populace and into military motor pools. Under a development contract with the U.S. Army, Ricardo, an international engineering firm, has finished building its first take on a new light tactical vehicle. One of the primary goals of the FED Alpha, which stands for Fuel Efficient Ground Vehicle Demonstrator, is to be more fuel efficient than current Army vehicles.

To reach this goal, the FED Alpha relies on a four-cylinder Cummins diesel engine and Goodyear low rolling resistance tires. Gears in the drive line use a special finish to help reduce friction. By contrast, the Humvee, currently in wide use by the Army, uses a 6.2-liter V-8 diesel engine. No figures have been released for the FED Alpha's actual fuel economy. … Read more

Tossing clothes into the wash when dirty is so last year, thanks to a discovery by chemists out of the University of California at Davis. Near-ordinary cotton may simply need be exposed to light to get busy killing bacteria and breaking down toxic chemicals such as pesticide residues.

Ning Liu, a doctoral student at UC Davis, worked with textile chemists Gang Sun and Jing Zhu to develop a method that incorporates a compound (2-AQC) into cotton fabrics. When exposed to light, it produces reactive oxygen species such as hydrogen peroxide that kill bacteria and break down toxins.

While Liu says 2-AQC is more expensive than other compounds, it is difficult to remove from cotton due to strong bonding, and cheaper equivalents should work, too.

"The new fabric has potential applications in biological and chemical protective clothing for health care, food processing, and farm workers, as well as military personnel," she says.

The team reported on its findings in the Journal of Materials Chemistry last month, shortly before another study out of the University of Iowa chronicled the vast presence of even drug-resistant disease-causing bacteria on hospital curtains.… Read more

Meet AlphaDog--it's BigDog on steroids.

This is our first glimpse of the brother of Boston Dynamics' robotic beast of burden, BigDog.

The vid below shows a lab prototype of the quadruped war robot, aka the Legged Squad Support System, or LS3, funded by DARPA and the Marine Corps.

The donkey-sized machine is designed to carry up to 400 pounds of gear and follow troops over rough terrain on missions of 20 miles and up to 24 hours.

That's more than BigDog's payload of 340 pounds and 12 miles; as a general rule, horses can comfortably carry up to 240 pounds. AlphaDog will have some degree of autonomy like animals, using computer vision to follow a leader or automatically trotting to GPS way points. … Read more

Robots will play a greater role in fighting wars in the future, and BigDog wants a piece of that action.

BigDog is both the silliest and scariest military robot out there. The recent video below from creator Boston Dynamics provides a retrospective on the DARPA-funded quadruped, which is designed as a load-carrying mule for soldiers.

The vid shows six years of BigDog evolution from 2004 through 2010. The 240-pound, all-terrain cyber-canine can tackle slopes up to 35 degrees, rubble, snow, mud, and water, and can carry a 340-pound load. That's handy since the average soldier load has increased dramatically in recent years.

You can't hear it in the video, but it sounds like a go-kart because it runs on a one-cylinder Leopard go-kart engine.

Its sensors include stereo vision, GPS, a gyroscope, and LIDAR--you can kick it and it'll keep on trucking. The machine once set a record for traveling 12.8 miles without stopping or refueling. It can run at speeds up to 4 mph.

No doubt BigDog is impressive, even awesome in its relentlessness, but also ridiculous. Boston Dynamics once had fun "weaponizing" the brute, perhaps inspired by that jocular BigDog Beta video by a pair of spandex-clad parodists.

One serious follow-up to BigDog is the Legged Squad Support System (LS3), also designed to lighten the load for dismounted troops.

"That machine will carry 400 pounds of payload on 20-mile missions in rough terrain, where wheeled vehicles can't go," says Marc Raibert of Boston Dynamics. "We have a lab prototype that we will show soon, and expect the first field prototype ready in summer 2012."

And since Boston Dynamics is working on other animal robots for the military that could conceivably run as fast as 70 mph, it's hard not to wonder whether BigDog could have the last laugh and the joke will be on us. … Read more

Technology development firm Cambridge Consultants has created a military targeting system that can track 5-inch shells traveling more than 1,000 mph, allowing gunners to improve their shooting.

The system, which the company calls the first of its kind, is based on a 3D holographic radar known as the Land and Surface Target Scorer (LSTS). It can track highly mobile targets in a cluttered radar field.

In recent trials at the Naval Surface Warfare Center, the radar system was mounted on a tethered pontoon to track projectiles in a 360-degree, 1,000-foot coverage zone.

The LSTS tracked the trajectory and burst points of inert projectiles fired by a naval gun at a rate of one per three seconds. A laptop showed the results in near real time. … Read more
