Cam-wielding RC car used to investigate roadside bomb, saves lives in Afghanistan
The US military spends billions of dollars each year beefing up wartime tech, but a low-budget hacked RC car recently served as an unlikely hero, saving six soliders' lives in Afghanistan. The home-built rig, which included a wireless security camera mounted on a Traxxas Stampede remote-controlled truck, cost about $500 when it was built in 2007. Since then, Army Staff Sgt. Christopher Fessenden has used it to locate roadside bombs, until it tripped a detonation sensor during a patrol last month, in turn saving Fessenden and fellow troops from coming head-to-head with 500 pounds of explosives. Unfortunately the RC cam didn't survive the attack, so Ernie, the solider's brother who built the first model, is currently working on a replacement. Sure, a half-grand may seem like a laughable sum compared to the Pentagon's annual budget, but if the proven gadget gets enough attention, perhaps Chinese-made toys will play a role in entertaining our kids, and protecting our troops.
Turing machine built from wood, scrap metal and magnets, 'geek' achievement unlocked (video)
We take it for granted nowadays that thumbnail-sized silicon chips can crunch through the most complex of calculations, but early last century, mathematical tasks were still being carried out by humans. It was around that time that one Alan Turing, Enigma code breaker and general computer science pioneer, came up with what was essentially a thought experiment, a mechanical machine capable of simulating and solving algorithms just like a grown-up CPU. Well, you know where this is going by now, one British software engineer decided to build just such a device, out of old bits and bobs he had lying around his geek lair, producing a working model that was recently shown off at the Maker Faire UK in Newcastle. The only downer, as he points out, is that it'd take "months to add two numbers together," but all good things start off humbly. Video after the break.
US Navy explains basic mechanical principles of a fire control computer -- in 1953 (video)
Bits, bytes and silicon transistors? Boy, you have it good -- back in 1953, state-of-the-art computers were made of gears, sprockets, chains and cams, and we trusted them to accurately wreck lives with ginormous naval guns. If you're wondering how that could possibly work, you don't have to go far -- a series of seven videos after the break show you how it was done, and which might even ingratiate you with the grizzled old neighbor who desperately wants you off his lawn.
HP V5020u camcorder does 1080p in style
HP's just outed a new camcorder, the 1080p loving V5020u. Among its other attractions, this camcorder boasts full HD 1080p video recording at a resolution up to 1920×1080, a built-in gyroscope for image stabilization, 10x digital zoom, a 5 megapixel sensor, a motion detector, a 2-inch LCD, and an SDHC slot for extra storage capacity. This bad boy, which we think is pretty good looking, will be available in October for $159.
UK surveillance cams may get mic'ed up to detect aggression
Pretty much every time we glance over at our friends in the UK, they seem to be implementing surveillance technology that surely wouldn't make George Orwell too thrilled. In the last two months alone we've seen those CCTV cams with accompanying loudspeakers debut in Middlesbrough, which was more recently followed by a handful of London cops getting some head-mounted cams. Sure, it's easy to invoke the spectre of Big Brother into any conversation about the expansion of the watchful eye of government, but the new discussions afoot have even us Yanks a little concerned for our British brethren. According to The Times, UK police are considering using high-powered microphones that will home in on a particular public conversation, if "aggressive tones" are detected, based on decibel level, pitch and the speed of the speaker's voice. Three hundred such microphones are already installed in cities around The Netherlands, including Groningen, Utrecht and Rotterdam, in locations such as government offices, city centers, and our favorite: "T-Mobile shops." We had no idea T-Mobile shops caused Dutch people to get so ornery -- maybe their highly-ranked customer service department didn't make it across the Atlantic yet.[Via The Inquirer]
