Video: Breath-over-IP concept is a fun way to creep out your friends

by Vladislav Savov posted Jul 17th 2009 at 5:46AM

This might have been a Crapgadget contender but for the fact it's a homemade system and therefore deserves some kudos for the ingenuity shown. An irrepressible geek by the name of Thomas Edwards has concocted a system for communicating breathing over the interwebs -- a surefire way to take your cyberstalking game to the next level. Employing an Arduino protoshield, AdaFruit Xport shield, Lantronix Xport Direct, and a Kestrel impeller to create the device, Thomas demonstrates a taste for obscure technology usually not seen outside of prototyping labs. Click through for video of a candle being blown out remotely, perhaps the one and only family-friendly use for an instrument like this.

Wireless USB 2.0 to dawn on the Japanese horizon?

by Vladislav Savov posted Jul 17th 2009 at 1:03AM

Japanese researchers at KDDI have spliced two technologies that didn't seem to have much of a future in the wireless realm -- USB and Infrared -- and come up with a method for achieving transmission speeds of up to 1Gbps. Their innovation is in overcoming a latency problem that until now prevented USB 2.0 transmissions from being converted into Infrared signals and then back into electronic form. While still very early in the development and standardization process, this is a tantalizing premise, especially with ever-increasing storage capacities in portable devices. The new communication medium, which admittedly sounds a lot like irSimple, will be demonstrated for the first time at the Wireless Japan 2009 exhibition later this month, but we wouldn't hold out hope for an imminent release.

Spintronics magic appears again, aims to vastly accelerate data storage and retrieval

by Darren Murph posted Jun 7th 2009 at 5:21AM

As the list of "awesome things that won't ever happen" grows ever longer, we've got a brilliant team of French physicists who have seemingly concocted a method for storing and retrieving data on hard discs that's around 100,000 times faster than usual. Yes, 100,000x. The trick is based around spintronics, an almost mythical procedure that involves the use of lasers, magnetic sensors and mutant abilities to shuffle data around at a dizzying rate. This particular method, however, improves upon the comparatively sluggish attempts of the past, as it uses photons that "modify the state of the electrons' magnetization on the storage surface." In layman's terms, this all means that the HDD you buy in 2098 will probably operate significantly faster than the one you picked up during Circuit City's going-out-of-business sale. Got it? Good.

Ericsson promises 42Mbps HSPA demo using multi-carrier technology

by Darren Murph posted Feb 12th 2009 at 8:21AM

Leave Ericsson alone for five seconds, and it goes and makes the technology it was just bragging about seem archaic. Just in case Telstra's 21Mbps Next G network seemed a bit -- how do you say, sluggish? -- Ericsson will be showcasing a new approach that enables peak downlink data rates of 42Mbps at Mobile World Congress. In order to achieve such tremendous speeds, it will rely on its so-called multi-carrier technology, which is the next (or is that next-next?) generation of HSPA. The secret? It allows users to "receive data simultaneously on two frequency channels," which doubles the data rate in the coverage area of an HSPA network and on the cell edge. The best part of all this isn't that you can one day look forward to crushing your cable modem with a wireless USB stick, it's that "one day" will be ready to happen before the dawn of 2010. Huzzah!

Honda's color-changing speedometer to drive out bad driving habits

by Darren Murph posted Nov 26th 2008 at 9:50AM

So, you've a lead foot? What of it, right? Honda's hoping to make that bad little habit vanish by using the tried and true guilt trip method, or more specifically, the Ecological Drive Assist System. For starters, the technology's ECON Mode works with the CVT and engine to "support more fuel-efficient driving." The real kicker, however, is the color-based "guidance function" -- drive like a granny, your speedo lights up green, drive a little wilder, and things get a bit blue, and if you toss fuel economy to the wind and let 'er rip, expect a full-on blue screen and the voice of God to come thundering through your sound system instructing that those horses be held. The EDAS should appear in the automaker's Insight hybrid as early as Spring 2009, though there's no word if it'll be standard equipment on the rumored S3000.

Production Tesla Roadster gets glorious hands-on: stifle your envy, please

by Darren Murph posted Nov 24th 2008 at 5:52PM

Here at Engadget, we hold a special place in our hearts for Mr. Jason Calacanis, but regardless of whose name is on the pink slip, there's no denying that the vehicle you're peering at above just struck all sorts of jealousy in your chest. This Very Orange (seriously) Tesla Roadster is one of the very first to be produced with the revamped drivetrain, and according to the lucky (lucky!) souls over at AutoblogGreen who were able to give it a go, the "new, higher torque motor immediately made its presence felt." All that aside, we know you're here for the photos, so head on down to the read link when you've got ten or so free minutes to shuffle through. Let's just say you'll have a new appreciation for one Drew Phillips (photographer) when you're done treating your retinas.

USB 3.0 demonstrations dazzle: uncompressed 1080p transfer proves simple

by Darren Murph posted Nov 19th 2008 at 5:47PM

You've been adequately teased with what all USB 3.0 (or SuperSpeed USB, as we tend to refer to it) can do, but a gaggle of companies took the chance in San Jose, California to really demonstrate just how quick the protocol is. Most notable was the demo by Synopsys, which prototyped an HDTV video transmission system based on USB 3.0 and showed to wide-mouthed onlookers that an uncompressed 1080p feed at 30 frames-per-second could be whisked along at around 450Mbps. Sure, USB 3.0 has wireless HD to watch out for, but given that said technology is currently on track for an August 2298 release, it could really do some tethered damage in the meanwhile.

Comcast gets serious about DOCSIS 3.0 rollouts

by Darren Murph posted Oct 22nd 2008 at 4:56PM

Alright Minneapolis, you've had your fun. Now it's time for another swath of Comcast markets to indulge in the lavish joys that only DOCSIS 3.0 can provide. For those unaware, the aforesaid technology enables 50Mbps internet to be delivered over the cable company's infrastructure, which brings it up to speed (ahem) with offerings by fiber-based carriers Verizon and AT&T. In the next few weeks, the DOCSIS 3.0-based "Extreme 50" option will bring 50Mbps down / 5Mbps up to subscribers in parts of New England, Philadelphia and New Jersey. Better still, the company announced its intentions to bring the $139.95 per month service to ten other big markets where it will reach "about 10 million homes and businesses in the next few months." Oh, and if that's just too much intarwebz for you to handle, an "Ultra" 22Mbps downstream service will be available for $62.95 per month.

Photonic breakthrough could mean 60x faster internet speeds

by Darren Murph posted Jul 16th 2008 at 10:01AM

Every so often, we get wind of some new "breakthrough" from a few guys / gals in a lab that promises to simply revolutionize the web. A team from the University of Sydney is the latest bunch to do so, claiming that a piece of scratched glass (or a Photonic Integrated Circuit, if we're being proper) could enable internet speeds 60 times faster than "current Australian networks." Essentially, the "circuit uses the scratch as a guide or a switching path for information," and the resulting product is "photonic technology that has terabit per second capacity." Call us when you folks get everything ironed out -- we'll be over at Sigbritt Löthberg's house.

Hydraulic transmission gives engines, wallets a break

by Darren Murph posted May 27th 2008 at 9:58AM

Another day, another potential find to avoid the imminent fuel crisis. On the docket today is Ernie Brookins' hybrid drive system, which "captures, compresses, and stores wasted drive-train energy produced when a vehicle's engine is running." Ernie here has concocted a hydraulic transmission that can reportedly power vehicles without the engine running all of the time, and he expects the solution to save motorists around 50-percent in fuel costs. Better still, the contraption could theoretically work on nearly any vehicle -- from school buses to grain trucks to high-octane Power Wheel Jeeps. As these things seem to always go, the project has hit a roadblock without a source of funding, so if any VCs out there are looking for a somewhat solid place to shove $250,000, give this man a ring.

Tesla's original transmission maker sues for back payment

by Nilay Patel posted Apr 15th 2008 at 6:32PM

The drama surrounding the Tesla Roadster's transmission and the company's attempts to build a system that can transmit power from the motor to the wheels without breaking under the strain took another strange twist today, with the revelation the that first supplier Tesla contracted to design the part is suing the company for $5.6M. Magna Powertrain USA says Tesla hired it to develop a two-speed transmission in September 2006, and when things fell behind schedule, Tesla canceled the contract and walked away without paying. Saucy! Of course, problems with the proposed two-speed transmission are why Tesla plans to ship early production Roadsters with "temporary" one-speed units and swap them out later, but there's no word on where the two-speed versions are going to come from apart from Tesla saying "We need to have more control over our fate and manage the process in house." Sure, sure, just as long as we get one for "testing," okay?

Super 3G hits 250Mbps downlink in NTT DoCoMo field test

by Darren Murph posted Mar 26th 2008 at 8:53AM

Just think -- this time next year, we'll all look back at this milestone and wonder how on Earth we thought it was impressive. For now, however, we wouldn't blame you for high-fiving everyone around, as NTT DoCoMo has stretched the boundaries again with a recent Super 3G field test. Reportedly, the outfit was able to record "a downlink transmission rate of 250Mbps over a high-speed wireless network in an outdoor test of an experimental Super 3G system," and while it's not quite the 300Mbps we'd heard about before, you won't find us kvetching. If all goes to plan, the firm is hoping to "complete development of the technologies required for the eventual launch of a Super 3G network" by 2009, but who knows how long we Americans will have to wait to indulge after that.

Tesla clarifies "temporary transmissions," say they're slower, not going to fail

by Nilay Patel posted Dec 19th 2007 at 8:36PM

We'd heard that problems with the Tesla Roadster's transmission were going to lead the company to ship the cars with "temporary" transmissions, but our friends over at AutoblogGreen were recently contacted by Tesla and told that while the company is indeed considering shipping cars with a different tranny than originally planned, they won't be designed to fail, as we'd originally heard. Rather, it'll be a single-speed transmission that won't allow the all-electric hot rod to run as fast as the planned two-speed version. Tesla still plans to swap out the units for the real deal when they're finally strong enough to handle the electric's massive torque, but at least now when Tesla owners are stranded by the side of the road they'll just need an extension cord, not a whole new transmission.

Tesla to deliver Roadsters with "temporary" transmissions?

by Nilay Patel posted Dec 13th 2007 at 9:02PM

The Tesla Roadster was supposed to be out before the end of the year, but it looks like the wicked-fast electric car won't make that target -- apparently the company is having problems finding a transmission strong enough to handle gear shifts while the car remains at full torque. The problem is somewhat unique to electric cars, and Tesla's got two different suppliers scrambling to find a solution -- but in the meantime, the company is considering providing vehicles outfitted with "temporary" transmissions that are basically guaranteed to fail after a few thousand miles. The first of these has already been built for company chairman Elon Musk, and Tesla is deciding whether to start shipping cars with the temporary units to other customers and then replacing them when a final transmission becomes available. That's the price of progress, we suppose, but something tells us quite a few people would rather just wait for the final product.

Fuji Television demonstrates visible light communications system

by Darren Murph posted Nov 23rd 2007 at 6:39AM

It's not like visible light communications is the new kid on the block or anything, but Fuji Television was busy showcasing a new flavor of the technology at Inter BEE 2007 that could assist deaf / hearing impaired individuals when watching TV. In the demonstration, a LED-backlit LCD TV displayed content while simultaneously beaming out information sans wires to a nearby PDA; the handheld was able to receive the textual data and display words to accompany the on-screen action. Not surprisingly, the communications system was developed by NEC, and it even supported selective distribution in order to transmit the correct information to the appropriate individual. No mention was made of an expected commercialization date, but feel free to check out a couple more shots of the setup after the break.
