Thiago writes "Here is an audio sampler I made with 4 IR LEDs and 4 IR sensors. When something reflective goes by one of the sensor/LED combos, it triggers an event on the computer. On the videos, I mount the device on a turntable and use coins to trigger sound samples of my choice. I'd also like to make the project open-source (or whatever applies to hardware) but know nothing about licenses for this."

zaktheduck writes "According to a recent press release, in anticipation of the new movie and the h2g2 website's sixth birthday, the BBC have relaunched the long-shelved h2g2 Mobile service. The new version of the popular community website allows access to the 7000+ and growing edited guide entries from PDAs, and smartphones. H2g2 had a WAP service back in 2001, aptly named "h2g2 on the Move", but was cancelled when the company faced financial trouble and was purchased by the BBC. Here's a copy of the old promotion page for the service."

Torrey Clark writes "Intel seems to be the first to ship a batch of dual core x86 64-bit processors to OEMs. Intel's first dual-core chip is the Intel Pentium Processor Extreme Edition 840. The new processor runs at 3.2 GHz, backs Intel's Hyper-Threading and is supported by the company's 955X Express chipsets, formerly code-named Glenwood. Dell also announced that it would be one of the first PC makers to ship Intel's new dual core Pentium Extreme." Reader wyckedone adds "AMD is set to ship their dual core Opteron processor, designed for servers, next week."

The network would also would be available to every individual in the city for $18 to $24 a month."

bigtallmofo writes "Google has added a mobile version of their local-search service to their lineup of mobile applications available from devices equipped with XHTML-enabled browsers. Previously available mobile Google applications include their mobile web and image search and their SMS service (beta) that allows users to enter their search queries and receive results via a text message. The day of receiving unsolicited coupons for your next latte as you walk by a Starbucks is one step closer."

pi42 writes "Some MIT students built this USB controlled disco dance floor for their dorm lounge. It was built in a week, has 1536 LEDs, 20,000 hand-soldered connections, and is capable of displaying 12-bit color. Check out videos and photos." You can even send the floor an email, though it might not write back.

An anonymous reader asks "I am searching for a box into which I can plug a hard drive (IDE or SCSI of various flavors) and automatically begin a secure deletion process (DoD 2250 compliant or the like would be good). This is normally for dead drives which need to be RMA-ed. Because of various regulations (HIPAA for starters), we need to at least attempt to do a good job clearing the disk. I've heard from a number of places, including this Slashdot story, that degaussing isn't great. There are software solutions out there, but in general, I want to toss a replacement hard drive in and not have to hunt around for hardware to put the bad drive in in order to run the software. Given the right case, a solid state drive, some SCSI cards and one of various pieces of software, I can imagine such a beast. Has anyone seen someone selling something like this?" No case-opening is necessary to use a USB/IDE converter, which might be a good middle ground. Any other ideas?

jangobongo writes "A machine built by the Purdue Society of Professional Engineers employed an outer-space theme and used steps that incorporated a bouncing water balloon, a fireman action figure fleeing a fire and weights attached to a spinning bicycle wheel to win the 18th national Purdue Rube Goldberg Machine Contest. The winning machine told the story of rocket being launched. As the rocket traveled into space, a meteor hit Earth and started a fire. While the mock fire was put out, the rocket turned on the flashlight to shine back down on Earth. A short video clip can be seen here. The contest was filmed by the Game Show Network to be featured on the network's show, 'Games Across America,' at some future date."

neutron_p writes "The goal of a terahertz transistor for high-speed computing and communications applications could now be within reach. A new type of transistor structure, invented by scientists at the University of Illinois, has broken the 600 gigahertz speed barrier. A new type of transistor - built from indium phosphide and indium gallium arsenide - is designed with a compositionally graded collector, base and emitter to reduce transit time and improve current density. With their pseudomorphic heterojunction bipolar transistor, the researchers have demonstrated a speed of 604 gigahertz - the fastest transistor operation to date."

Techguy666 writes "Gee, this is a suprise. Researchers have found that keyboards harbor bacteria and super-germs. This is particularly interesting this time because this research noted that there is a lot of computer use in hospitals and they're finding it really difficult to sterilize them."

VL writes "Ping times suck? Too much lag? If your loved ones are hogging all your bandwidth with P2P and torrents, you'll want to check out the D-Link DGL-4300 Wireless 108G Gaming Router. This is a router designed for gamers that also happens to be a great router for regular folks."

misterpies writes "Of the many jobs robots could be put to use, here's one I'll bet not many slashdotters have considered - camel jockeys. According to the BBC, from next year racing camels in the United Arab Emirates will be ridden by robots. And for once, the folks put out of work won't be complaining - mostly children (some as young as four) who are reportedly abducted or sold by their families to unscrupulous racing-camel owners. How long until we see robots take over from humans in other sports?"

FalconZero writes "For those of you with superhuman aspirations, your dream may be a step closer; New Scientist (recently) and the Japan Times (last year) covered Yoshiyuki Sankai's work at the University of Tsukuba in Japan developing powered exoskeletons with commercial versions expected soon costing between $14,000 and $19,000 (£7,500-£10,000). Other work with exoskeletons previously covered here(1), here(2) and here(3)."

thelastguardian writes "With 400,000 American construction workers injured each year, and a typical American house takeing at least six months to complete, house building had been the same tiring gritty job for 20,000 years. For this problem, Behrokh Khoshnevis has a solution: A Robotic House Builder. An eight feet tall and six feet wide phototype house building machine, with ceramic mixing ability/computer control back-end, is currently building solid walls inside University of Southern California. To add to the excitement, even NASA is evaluating the machine as a builder on Moon using moondust- Who said moondust is useless?"

Slicker writes "S. Korea and N. Korea (aka the ROK and DPRK, respectively) share the most heavily fortified border that has ever existed. Now the ROK is considering deployment of armed robots." Not expected until sometime in the 2010s. From the article: "Robots with weapons mounted on their frames are each expected to be able to observe from 2 and 1 kilometers during the day and night, respectively, and will have the capability to record voices and take pictures in a 180-degree circle."

Nimrangul writes "Hitachi has recently announced perpendicular recording with their harddrives, allowing for 10 times the data storage on a disk, meaning 20 G microdrives are on their way as soon as 2007. Hitachi is so pleased with this technological development that it has broken into song." This is, without a doubt, the most surreal thing I've seen today. Flash Required.

rhythmx writes "Details of this bill have been previously covered on Slashdot. SBC has since put up TV ads and a website saying that our telecom laws need to be changed. From their propaganda, "The Texas legislature has the opportunity to modernize telecom regulation and promote innovation to finally reach our goals for new technologies and enhanced consumer benefits." They hardy even mention the bill itself, basically only that it is "Good for Texas -- Good for Texans." This bill has already passed through the House and is now in the Texas state Senate."

jg21 writes "LinuxWorld's senior editor James Turner reports this month on what he calls The State of Laptop Linux in 2005 and says it's a lot better than it was in 2004, but adds - after conducting his own new test to see if any Linux distro is yet really laptop-ready: "What's needed to make things better? Well, the Linux community needs to address the device driver crisis." Turner acknowledges that binary-only drivers are a sore spot with free software purists, but says he'd "rather have a fully functional, if closed, Nvidia driver than a reverse-engineered one that limps along." Overall though he concludes that widespread laptop Linux is much closer now."

EconolineCrush writes "Slashdot recently covered the launch of NVIDIA's nForce 4 SLI chipset for Intel processors, and although early reviews fawned over the chipset's performance, closer examination reveals several shortcomings that the initial wave of coverage failed to document. Problems with stability, drivers, and the chipset's oft-praised hardware-accelerated firewall and Gigabit Ethernet controller escaped the scrutiny of many reviews."
