Intel Thunderbolt: a closer look (updated with video)
So what's this Thunderbolt stuff, and why is it in your new MacBook Pro? Intel just broke it down for us, and now we'll do the same for you. Simply put, Thunderbolt's a familiar-looking port, a brand-new chip, and a cord, which allows devices to pipe two data streams simultaneously -- in both directions -- over a single cable at up to 10 gigabits per second to start, primarily using PCI Express x4 for data and DisplayPort for video. The Thunderbolt controller chip -- required for the system, but Intel says it's hardware-agnostic and doesn't require an Intel processor or chipset to use -- acts as a miniature router of sorts that rapidly switches between the two bidirectional channels of data. Sounds great, but why would you want to buy into yet another copper cord? Intel defends that Thunderbolt will be backwards and forwards-compatible depending on the cable used. Representatives explained that the basic system can work with any other PCI Express 2.0-compatible I/O system with, say, a FireWire or eSATA adapter doing the dirty work --Intel wouldn't specifically comment on USB 3.0 -- and that the port you'll find in new MacBook Pros and storage devices can actually take an optical cable when those are cost-effective enough to roll out, because Intel will eventually bake the optical transceivers into the cables themselves. In the meanwhile, you can get up to three meters of range out of a basic cable, plus a fairly generous 10 watts of power over the bus, and since Thunderbolt devices are designed to be daisy-chained, you may be able to get another three meters for each device you add on that sports a pair of the ports. Though Intel wasn't talking about likely prices for the chips or cables in even the most general terms, Promise and LaCie had prototype devices on hand headed to the market soon -- get a peek at them and a closer look at the cable in our gallery below, and we'll have video up in a little while too. Update: Looks like LaCie's product now has a name and vague release date: it's the LaCie Little Big Disk, coming this summer, with a pair of solid state drives inside. Update 2: Video after the break -- get a load of Thunderbolt streaming four 1080p clips from a MacBook Pro and attached Promise NAS simultaneously! %Gallery-117530%
GoDAP amplifies your mobile audio and provides optical output for iPhone 4
Most of the gadgets we're seeing here at CES 2011 this year aren't too big a surprise -- we set up meetings even before we walked into the convention center, and the surprise is in seeing the new gadgets we've only read about before. But the GoDAP was a surprise, found just by walking around the show floor and checking out the booths. It's made a Japanese company named VentureCraft, and it's a clip-on unit for the iPhone that not only works as a rechargeable battery, but also serves as a headphone amp, spiking up the output audio on your iPhone 3GS or 4. The current model for the 3GS isn't quite as impressive as the new model -- it's just basically got a volume control (though the audio heard through headphones does sound really clear and loud). But the iPhone 4 model (of which we only saw a prototype on the show floor -- the real thing "will probably be thinner," according to VentureCraft, and should be ready to ship around April) is really interesting. It has digital audio output, and can send it through a optical cable in either 96k/24bit or 48k sampling rate (adjusted via a toggle). That means you can use the DAC port to kick out audio to a home theater system directly from the iPhone itself, and because the amp is running, it'll sound that much better. The frequency response is listed as 10 Hz to 120 kHz and suitable headphone impedance is listed as 16-100 ohms. The op-amp is a Texas Instruments/Burr-Brown running on each channel, which all adds up to some pristine digital audio output. These are billed as battery chargers as well, but we suspect they may be more of a drain than a dedicated battery -- while you use the amp, you'll probably need to just keep it plugged in. The unit isn't cheap -- the 3GS version (without optical) runs $199 shipped from Japan, and the iPhone 4 version will probably be somewhere between $300-350. That is shipped, VentureCraft told us -- no extra charge, even though the unit is coming from Japan. But come April when this thing is ready, the right user might find it just what they need. We've got a quick video from the booth on the next page.
Accused Xbox 360 modder finds case pleasantly dismissed
The case of 28-year old CSU student Matthew Crippen has come and gone. Arrested last year on Digital Millennium Copyright Act violations -- specifically, for modding Xbox 360s to enable them to play pirated games -- federal prosecutor Allen Chiu announced on the third day of trial that the government was dropping its case against him "based on fairness and justice." It's not a complete surprise: according to Wired, on the previous day (Wednesday), an undercover agent testifying against Crippen claimed the defendant used a pirated game to test a modded console in his presence. That detail, required for the prosecution's case (the use of pirated software), was never mentioned in any of the previous reports or sworn declarations, so once the judge dismissed it as evidence, the case against Crippen hit a snag. Source link's got the full, very interesting tale, but if you're patient, there's always a chance one of the Law and Orders will pick up the story in the years to come.
Kinect now offers a stealth mode, courtesy of optical camouflage hack (video)
You've seen so many Kinect hacks by now that you probably think you know them all -- but wait, have you seen one that makes you look like Predator when he's busy predatorizing the populace? Or one that lets you reenact your favorite Metal Gear Solid scenes with Snake's camo turned on? Yup, a Japanese coder by the name of Takayuki Fukatsu has exploited the versatile openFrameworks to give Kinect a mode where it tracks your movement and position, but turns the dull details of your visage into an almost perfectly transparent outline. Of course, you're not actually transparent, it looks to be just the system skinning an image of the background onto the contours of your body in real time, but man, it sure is cool to look at. You can do so for yourself with the video after the break.
Intel Light Peak on track for release in first half of 2011?
10Gbps. In both directions. At the same time. That's been the tantalizing promise of Intel's Light Peak optical interconnect, and now we're hearing its penchant for speed is overflowing into the company's roadmap. CNET cites a source familiar with developments behind the scenes in reporting that Light Peak is expected to arrive in the early part of next year, slightly accelerating the already known plans for delivering the technology at some point in 2011. We've already been graced with a set of Light Peak-enabled prototypes, so you could've guessed things were gathering pace, but it's always good to get the odd bit of anonymous confirmation that things are moving along swiftly. And hey, when Light Peak hardware finally drops, we can just switch gears and start salivating over improvements that'll lift that 10Gbps ceiling even further.
Intel's Light Peak optical interconnect shrinks slightly, LaCie, WD, Compal and Avid begin prototyping
Intel's Light Peak isn't setting any new speed records at IDF 2010 -- it's still rated at 10Gbps for now -- but the optical data transfer system is finally looking like it might appear in some actual products. As you can see immediately above, a Light Peak to HDMI converter has shrunk considerably since May, and a number of optically-infused sample products were on display at Intel's Light Peak booth. Compal's got a laptop with the optical interconnect built in, while Western Digital showed an external hard drive, from which the Compal could pull and edit multimedia in real-time using a Light Peak-enabled Avid rackmount. Meanwhile, LaCie showed off what appeared to be a 4big Quadra RAID array with two Light Peak ports catapulting high-definition video content at 770MB/s to a nearby Samsung TV, though we should warn you that the TV itself was a bit of a hack job, and not a collaboration with Samsung -- note the big, honking EVGA video card sticking out of the back. Though obviously a good bit of work went into these prototypes, Intel reps told us none would necessarily become a reality. Either way, don't expect to see Light Peak products until sometime next year.
All-optical quantum communication networks nearly realized, 'Answers to Life' airing at 9PM
Ready to get swept away into the wild, wild abyss known as quantum computing? If not, we're certain there's a less mentally taxing post above or below, but for those who answered the call, researchers at the University of California Santa Cruz have a doozie to share. A team of whiz kids at the institution have developed a minuscule optical device that's built into a silicon chip, and it's capable of reducing the speed of light by a factor of 1,200. If you're wondering why on Earth humans would be interested in doing such a thing, here's the long and short of it: the ability to control light pulses on an integrated chip-based platform "is a major step toward the realization of all-optical quantum communication networks, with potentially vast improvements in ultra-low-power performance." Today, data transmitted along optical fibers must still eventually be converted to electronic signals before they're finally understood, but the promise of an all-optical data processing system could obviously reduce inefficiencies and create communication networks that are far quicker and more robust. There's still no telling how far we are from this becoming a reality -- after all, we've been hearing similar since at least 2006 -- but at least these folks seem to be onto something good... even if it's all too familiar.
Intel's 50Gbps Silicon Photonics Link shines a light on future computers (video)
Using copper cables to transfer data around a computer? Get your head out of the sand, Grandpa! Intel thinks that's on the outs and is touting its recent accomplishments with Silicon Photonics and integrated lasers, using light pulses to move data at 50Gbps (last time we heard Intel tout the tech was when it hit 40Gbps speeds in 2007). The emphasis is on low-cost, high-speed fiber optics, the removal of cable clutter, and with the speed boost, the ability to try new system designs by being able to space chips and components farther apart from one another without as much hit on speed -- all theoretical at this point, of course. Researchers hopes to hit terabit per second speeds further down the line. As for John Q. Consumer, enjoy the progress from afar but don't count on seeing this technology hit Newegg anytime soon. Video after the break.
Sony, Tohoku University develop blue-violet laser with 100 watt output, eyeing 1TB optical disk future?
As much as some would like to envision a world entirely bereft of disk-based media, with Blu-ray being the medium's swan song, that ain't happening. Sony's already looking to the future, and in cahoots with Tohoku University, it has developed a blue-violet laser capable of 100 watt output. That's reportedly more than 100 times the "world's highest output values for conventional blue-violet pulse semiconductor lasers." In the press release, the company said its tested using such technology for next-generation, large-capacity optical disc-storage, and while that doesn't say too much at face value, the Examiner reports (by way of various Japanese news outlets) that it equates to 20 times the storage of current Blu-ray disks, or about 1TB of data. Don't worry, we're sure all those 4K 3D films will still find a way to justify a "barebones" release dearth of features before magically making room for a second (and even third) Special Edition in time for respective holiday seasons.
Swiftpoint's tiny mouse finally up for pre-order, shipping in August
It's been a long couple of years since we last heard from Swiftpoint, but the company is back with a (tiny) bang and introducing its eponymous ultraportable mouse. Touting a pen-like grip, tilt-scrolling, and a 30 to 40 percent better efficiency than your touchpad, this little thumb accessory wants to be seen as the solver of an eternal problem -- namely, getting all the utility of a desktop rodent without having to deal with its full size. Whether it lives up to that lofty goal will require some fingers-on time to determine, but the Swiftpoint does a very credible job on the battery front: it can turn a 30-second charge into an hour's use and can last 3 to 4 weeks on a fully juiced cell. It all sounds quite appealing, but be prepared for some sticker shock as the pre-order price is £67 in the UK or $70 in the USA... and that's with a 10 percent early bird discount included. We might just wait till these hit the sales before grabbing one. [Thanks, Patrick]
Intel demonstrates Light Peak on a laptop, says 10Gbps speeds are only the beginning
Folks in Brussels for Intel's European research showcase got to get their hands on the company's Light Peak this week, with the first demonstration of the optical cable technology running on a laptop. Outfitted with a 12mm square chip that converts the optical signal into data the machine can read, two separate HD video streams were piped to a nearby TV, which displayed them with the help of a converter box -- a necessary evil until the Light Peak chips are developed for the display side of things. According to Justin Rattner, Intel's CTO, the current 10Gb / second speeds are just the beginning. "We expect to increase that speed dramatically. You'll see multiple displays being served by a single Light Peak connection. There's almost no limit to the bandwidth -- fibers can carry trillions of bits per second."
Sony's 35-inch atracTable to be 'industrialized' in June, show Microsoft how it's done (video)
Swiss company Atracsys swims in the same waters as Microsoft's mythical Surface beast -- namely, multitouch horizontal displays -- but where it might differ from its more lauded competitor is in actually bringing its hardware to wider markets. Having sold the tech knowhow to Sony, the company is today informing the world that its atracTable is ready for mass production and commercialization this June. We've been told that prototype designs are now "finished," leaving only the marketing, pricing and distribution details to be worked out. A high-contrast, Full HD screen is promised, which will be able to communicate with your mobile devices (naturally) or respond to motion input picked up by a pair of Sony's camcorders which come built in. Skip past the break for a couple of video demos from last year.
Intel says Light Peak coming next year, can and will coexist with USB 3.0
How do you sell a generation of hardware manufacturers on yet another standard? If you're Intel, you tell them that it'll transfer files at 10Gbps and is compatible with every major protocol that came before... and if that doesn't work, you simply fail to give your competitor hardware support. But PC World reports that while Intel is still dragging its feet regarding USB 3.0, it's planning to have Light Peak fiber optic devices in the market next year. Intel insists Light Peak isn't meant to replace USB, in so much as it can use the same ports and protocols (photographic evidence above), but at the same time it's not shying away from the possibility of obliterating its copper competition with beams of light. "In some sense we'd... like to build the last cable you'll ever need," said Intel's Kevin Kahn. Now, we're not going to rag on Light Peak, because we honestly love the idea of consolidated fiber optic connectivity. We just want to know now whether we should bother locking ourselves into a USB 3.0 ecosystem if better things are just around the corner.
Germanium lasers offer ray of hope for optical computing
Bandwidth scarcity, is there any more pressing global issue that we're faced with today? We think not. Given the exponential growth in both computing power and software's exploitation and expectation of greater resources, it's no surprise that at some point we'll have to look beyond simple electrical currents as the transporters of our data. One bold step taken in that direction has been the demonstration of an operational germanium-on-silicon laser by researchers at MIT. By tweaking the electron count in germanium atoms with the help of some added phosphorous, they've been able to coax them into a photon-emitting state of being -- something nobody thought possible with indirect bandgap semiconductors. Perhaps the best part of this is that germanium can be integrated relatively easily into current manufacturing processes, meaning that light-based internal communication within our computers is now at least a tiny bit closer to becoming a reality.
RIM's optical trackpads: they weren't joking about the 'optical' part
Thinking about how your phone's touchscreen operates, you might assume that the so-called optical pads that have been making appearances on recent BlackBerrys (among other devices) operate in a similar fashion -- but you'd be wrong. RIM's official BlackBerry blog is chiming in today to drop some knowledge on us dullards, and it turns out that "optical" isn't just a cute nickname -- the pads do actually operate in much the same way as modern desktop mice, using a low-res infrared camera to capture movement across the surface and translate it into movement. In practical terms, what this means is that you don't need a conductive surface to operate the pad -- you can use pretty much anything that the sensor can see, so a gloved hand (for instance) is theoretically good to go. That being said, don't expect to be snapping photos with your "camera" any time soon -- we're literally talking about a handful of grayscale pixels here, which should make it only marginally better than the Droid's cam.
MIT gestural computing makes multitouch look old hat
Ah, the MIT Media Lab, home to Big Bird's illegitimate progeny, augmented reality projects aplenty, and now three-dimensional gestural computing. The new bi-directional display being demoed by the Cambridge-based boffins performs both multitouch functions that we're familiar with and hand movement recognition in the space in front of the screen -- which we're also familiar with, but mostly from the movies. The gestural motion tracking is done via embedded optical sensors behind the display, which are allowed to see what you're doing by the LCD alternating rapidly (invisible to the human eye, but probably not to human pedantry) between what it's displaying to the viewer and a pattern for the camera array. This differs from projects like Natal, which have the camera offset from the display and therefore cannot work at short distances, but if you want even more detail, you'll find it in the informative video after the break.

Dell SX2210T vs. HP L2105tm: optical multitouch head-to-head review
Dell and HP, HP and Dell. The United States' two biggest computer hardware manufacturers, and two of the world's top three, have tended to match each other step for step, so it's no surprise that Dell's recently released SX2210T was quickly followed by a Compaq L2105tm from its closest rival. Measuring 21.5 inches each, with 1920 x 1080 resolution, 1,000:1 contrast ratio, and optical multitouch technology under their chunky bezels, these two models represent the biggest mainstream push for touchscreen computing yet. Functionally identical to standard monitors, they offer the added benefit of letting you input your heart's urges and desires using swipes, gestures and flicks, and we've plucked one of each panel to see how this all plays out for ourselves.

Ask Engadget HD: How do I get the best audio from my PS3, without HDMI?
Once you've actually decided what hardware to purchase, avoided the perilous purchasing decisions involved in finding cables, but actually setting it up can trip up the newbies among us. Suck is our friend David's problem, trying to figure out if lossless audio is a possibility for his HDMI-less receiver: "I read your article and I would like further advice. I have the brand new PS3, which I'm going to use with a 1080p Sony Bravia - the video is fine..HDMI to the tv. The problem is that I have an ONKYO THX 7.1 system (really 5.1), and there is no HDMI, so I plan on using an optical audio cable from the PS3 into the receiver. How do i get the best sound? Will the PS3 decode the trueHD (or whatever it is) and send the full spectrum of sound across the optical to the receiver? Will NOT having the HDMI to the receiver affect my sound, or will the PS3 internal decoding send a perfect lossless sound to my non-HDMI receiver?" Just in case our HD 101 explanation wasn't enough (First off, S/PDIF transmission -- over either optical TOSLINK or coax -- does not have the bandwidth to carry Dolby TrueHD or DTS-HD MA signals. If you connect your Blu-ray player to your receiver with optical or coax, the audio will "fall back" to Dolby Digital, DTS or two-channel PCM -- lossless, but only two channels,) any tips on how David can get the highest audio quality possible out of the equipment he has? Of course, if you think replacing one of the components is a better choice, that's always an option as well. Got a burning question that you'd love to toss out for Engadget HD (or its readers) to take a look at? Tired of Google's blank stares when you ask for real-world experiences? Hit us up at ask at engadgethd dawt com and keep an eye on this space -- your inquiry could be next.
Hitachi and Toshiba subpoenaed in DOJ optical drive price fixing probe
We kinda knew that there couldn't be any antitrust smoke without the fire of market collusion, and sure enough, Sony Optiarc has been joined on the naughty step by Hitachi-LG Data Storage and Toshiba Samsung Storage Technology Corp. As the names should tell you, these are joint ventures involving some of the world's biggest electronics manufacturers, whose American optical drive divisions appear to be under suspicion of fixing prices. We'd have expected Hitachi and LG to wise up after paying out fines for LCD price fixing recently, but when you look at Hitachi's stock trading up after this news -- with traders confident any forthcoming fines will be too small to dent the company's bottom line -- maybe "by hook or by crook" is actually a viable business plan?
Sony Optiarc garners unwanted attention from DOJ for possible Blu-ray or DVD price fixing
In a filing with the Tokyo Stock Exchange this morning, Sony has revealed a request for information from the US Department of Justice regarding its optical drive production arm, Sony Optiarc. While the same filing indicates the Japanese giant's belief that this information gathering is part of a wider investigation into competition in the optical drive market, we've yet to hear of any other companies facing the same request. If you were feeling disgruntled with the pace of Blu-ray price drops, this might just be your moment of vindication... or it could be a storm in a teacup. There's really not enough information to tell either way right now, but if we know anything about the DOJ, it's that it loves shaking down naughty corporations. We'll keep a careful eye on this as it develops.
