NES light gun gets a laser upgrade, fulfils countless childhood dreams (video)
While it's not the DL-44 heavy blaster we've been holding out for, this Nintendo Zapper is almost as cool. Using the classic Duck Hunt light gun from the original NES, the team at North Street Labs created their own laser pistol. Using a 445nm diode, some batteries, wiring and imagination, the light gun was painstakingly put together, complete with physical safety lock and custom aim-assisting heat sink. The end result is a bona fide laser shootin' gun, capable of not only setting alight matches from a distance, but setting the curtains on fire too (probably). See it in action in the video after the break, where it also tops out their laser meter, rating it -- at least -- at an eyeball popping 2W. Then tap up the source to see how -- for educational purposes -- you could make your own.
Sony, Sumitomo push laser projectors forward with a new, more powerful green laser diode
As cool as lasers are, so far there are precious few commercially available display devices available that use them. That may change with this new green semiconductor laser diode announced by Sony and Sumitomo, capable of the brightness necessary to replace the more expensive light sources used to fill in the middle of the RGB setup. According to the two companies, it's the world's first one capable of over 100mW power at 530nm, which they think will make it a fit for both advanced projectors and compact light projectors. Check after the break for more details on how the technology came to be -- drawing heavily on Sumitomo's production techniques and Sony's GaN laser technology developed with Blu-ray -- we'll let you know when there's a LaserVue or REDray setup priced for general consumption.
T-rays produce 3Gbps short-range wireless, make WiFi pout in the corner
The last time we saw T-rays, they were busy scanning bodies for tumors and security threats. Six researchers from the Tokyo Institute of Technology are now aiming the terahertz-level frequencies at a less organic target: fast wireless. Running at 542GHz, a rate that makes 60GHz ultra wideband look pokey, the scientists are sending data through the ether at about 3Gbps. The speed isn't as fast as the 7Gbps peak of WiGig, and the bandwidth runs dry at just 33 feet away, but it comes out of a resonant tunneling diode measuring 0.04 square inches -- definitely small enough to fit into a smartphone. The speed could magnify using higher frequencies and power levels, too, with 100Gbps being the dream. Knowing that it can take years for academic papers to translate to real products, we're not holding our breath for T-ray routers anytime soon. Still, the technology could make wideband a realistic option for handhelds and put the mere 1.3Gbps of 802.11ac WiFi to shame. [Thanks, Andrew.

MIT slinks into a cafe, orders a side of photonic chips on silicon
Whiz-kids the world over have been making significant progress on the development of photonic chips -- devices that "use light beams instead of electrons to carry out their computational tasks." But now, MIT has taken the next major leap, filling in "a crucial piece of the puzzle" that just might allow for the creation of photonic chips on the standard silicon material that underlies most of today's electronics. Today, data can travel via light beams shot over through optical fibers, and once it arrives, it's "converted into electronic form, processed through electronic circuits and then converted back to light using a laser." What a waste. If MIT's research bears fruit, the resulting product could nix those extra steps, allowing the light signal to be processed directly. Caroline Ross, the Toyota Professor of Materials Science and Engineering at MIT, calls it a diode for light; to construct it, researchers had to locate a material that was both transparent and magnetic. In other words, a material that only exists in the Chamber of Secrets. Hit the source link for the rest of the tale.
Caltech researchers devise acoustic diode that sends sound one-way, could harvest energy
Sound has this habit of traveling in more than one direction -- useful in most circumstances, but not so welcome when a person in one room is looking for a little peace and quiet while someone in the next is blasting music. Sound-proofing is one solution to that problem, but some researchers at Caltech say they've now come up with a better one: an acoustic diode that can be tuned to allow sound to pass through in only one direction. As you might expect, however, that's all still very much in the early stages, but the researchers say the technology could eventually allow for "true soundproofing," or even be used for other purposes, like scavenging sound energy from structural vibrations and turning that into electricity. The official announcement with some of the finer details is after the break, and the researchers' full paper is published in the July 24th issue of Nature Materials.
Ford car seat prototype keeps its sensors on your heart, so you can keep your eyes on the road
Chevy had the whole "Heartbeat of America" thing cornered in the 80s, but now its Ford's turn to get in on the action. The car maker's European research team unveiled a prototype car seat capable of monitoring a driver's heart courtesy of six embedded electrodes, which can take measurements without coming in direct contact with skin. The technology, the latest in a recent string of health-related in-vehicle concepts from the company, can detect whether the driver is having a heart attack and transmit that information to the vehicle's safety system. According to the researchers, the system is already highly accurate in its prototype state, making correct readings for 98 percent of drive time with 95 percent of the drivers tested. For more information on the system, check the video and press release after the break.
Scientists improve blue OLED efficiency, don't promise everlasting light
Although this is not the first time we've seen an efficiency increase in blue OLEDs, it's worth noting that their proposed cap of productivity up to this point was a lowly five percent. It's exciting to learn, therefore, about a breakthrough by professor John Kieffer and graduate student Changgua Zhen from the University of Michigan, which has resulted in them successfully increasing azure diode power efficiency by 100 percent. The duo, accompanied by some bright minds in Singapore, manipulated performance controllers by rearranging OLED molecules in a computer model, improving material characteristics. In simple terms though, we're still looking at a measly ten percent efficiency, so we'll see where they take it from here.
University of Central Florida's miniature laser diode aims to speed up networking
The use of laser as a means of data transmission is hardly anything new, but the current crop of laser diodes can only handle so much stress, provided that they don't fail in the first place. Luckily, the geniuses over at the University of Central Florida are about to deliver a smaller yet more intense and more reliable diode, which will lead to many more potential applications even beyond the scope of networking -- think cheaper, more effective hair removal. Little is said about how Professor Dennis Deppe's team made this possible, but once they work out how to optimize the operating voltage for better efficiency, Deppe reckons we'll see diode-embedded high speed, high bandwidth cables in the shops in four or five years' time. Seriously, we'd do anything to keep our latency low for some HD gaming action.
Sony releases 400mW-output blue-violet laser diode, could make BDXL blossom
Now that the BDXL spec is finalized, a handful of DVR announcements have trickled out to support the higher-capacity Blu-ray format. Sony's release of the SLD3237VF 400mW-output blue-violet laser diode, however, could flat-out open the floodgates. That's because, besides supporting the new larger capacity standard, it's the first diode of its kind to have an output of 400mW or higher. This gives manufacturers more flexibility in their hardware design to use a wider array of optical components. The cost for the part itself is roughly $12, but no telling what kind of premium it'll actually entail by the time it hits retail. We do know that all that additional memory should provide plenty breathing room for higher production 3D Blu-ray discs in the future, or enough HD bonus features space to make The Lord of the Rings extended edition box go on a serious South Beach diet.
Mitsubishi Chemical to produce laser diodes for BD pick-up heads
Given that Sharp will obviously be needing a few high-power laser diodes to go into its forthcoming 8x Blu-ray burners, it's good to see Mitsubishi Chemical hopping in the fabrication game in order to lower costs and keep consumers smiling. A new report asserts that the previously mentioned company will be dedicating at least some of its efforts to producing high-power (200 to 300mW) laser diodes, which are currently in short supply and used in the pick-up heads of BD writers. As it stands, just Sony, Nichia and Sharp are producing these things in volume, though a fourth wheel will certainly be welcome. There's no word on when exactly Mitsu Chemical plans to ramp up production, but the sooner the better, we say.
Physicists develop plastic semiconductors for laser diode use
Not to get all scientific on you or anything, but a team of Imperial physicists have just figured out a way to use plastics in laser diodes. For the uninitiated, scientists have been unable to make plastic semiconductor laser diodes because they had not yet found / developed "any plastics that could sustain a large enough current whilst also supporting the efficient light emission needed to produce a laser beam." Now, however, that obstacle has reportedly been overcome by making minor tweaks to a given plastic's chemical structure, and the resulting material will transport charges some 200 times better than before without impeding its ability to emit light. By the sound of things, the crew behind the breakthrough isn't quite ready to offer up the solution to manufacturers, but with a bit more work, we suspect that notion will change.[Via Slashdot]
Sharp plans 8x+ Blu-ray burners by 2010
Sharp is continuing to move the bar in blue laser technology, recently unveiling a higher power (250mW) 6x Blu-ray recording laser, but more importantly tipped its hand regarding plans for 8x blue laser diodes by 2009. Those lasers will be able to output 300mW, followed by 400mW varieties capable of up to 12x speeds by 2010. Looks like blue laser shortages are a thing of the past, now we'll see how quickly speed -- and possibly multilayer discs -- can ramp up.[Via afterdawn]
US Trade Commission investigates Blu-ray patent
While we hear Sony has kept the party going non-stop since HD DVD's demise, the US International Trade Commission has stepped in as the role of the party pooper. Gertrude Neumark Rothschild, a former Columbia University professor, has filed a complaint with the ITC over what she says is infringement for patent she owns on certain light-emitting and laser diodes contained in Blu-ray players and other electronics. The commission has voted to investigate the claim, though they have "not yet made any decision on the merits of the case." Rothschild's complaint lists over 30 companies, including Sony, Samsung, Toshiba and Nokia.
Atmel intros 'industry's smallest' laser diode driver for HD DVD / Blu-ray
Atmel, the same firm known for cranking out uber-small GPS chips, has now created the "industry's smallest laser diode driver solution" for HD DVD, Blu-ray, DVD, and CD formats. The ATR0881 laser diode driver IC is available now and is designed for use in combination drives that play nice with all of the aforementioned discs. Notably, the ATR0881 itself is housed in a minuscule four- x four-millimeter QFN24 package, and should prove extremely useful in half-height combo drives as well as slim drives found in laptops. Smaller optical drives that handle every format harmoniously? Count us in.
PS3 price could drop $100 due to Blu-ray diode supply
Hope springs again for gamers who just can't bring themselves to drop $600 on a PS3. DigiTimes reports that Sony's blue-violet laser diode manufacturing plant will increase production and this could, "according to Taiwan-based makers of game consoles and components," drop the PS3 price by $100. Now let's see if those savings are passed on to consumers. Despite what Sony says, this magical $100 reduction is being batted around due to tech upgrades in the console and other factors discussed by analysts.The article also discusses the production cost drop of the Xbox 360. According to research firm iSuppli the cost to manufacture the Xbox 360 is now $323.30, while it profitably retails for $399. The PS3 costs $840.35 to manufacture, in its current state of production, and retails for $599. We'll have to wait to see the NPD sales data later this month to see how well the PS3 sold in April and if more fuel gets added to the price-drop fire. Although, if the PS3 had a game other than Resistance it might be selling better. Oh well, the purchase of a PS3 was an investment in the future, wasn't it? At least the PS2 is still worth every one of the 13,000 pennies it costs to purchase.Update: DigiTimes used data from last November's iSuppli report and marked it as May data. The comparison of estimated material cost is valid for PS3 and the Xbox 360 in November of '06. Chances are production costs have declined further since. iSuppli plans to do a new cost analysis soon.

Blue lasers coming down in price, PS3 to follow?
Sony's semiconductor subsidiary recently announced an increase in blue-violet laser diode production, with a monthly capacity of 1.7 million, and capability to produce up to five million with future upgrades. In June the diodes are expected to cost around $8 per diode in bulk, as compared to a price of $125 per drive (including the diode and other parts) when they came onto the market last year. Analysts predict that the lower cost of materials will likely drive manufacturers of blue-laser products to lower their own prices, with the PlayStation 3 benefiting from this reduction by allowing Sony to reduce the price, possibly even lower than $499, to be very competitive with the Xbox 360 Elite model. Of course, Toshiba could also theoretically take advantage of similar cost savings to reduce the price of their own HD DVD players. Perhaps that Wal-mart player isn't such a far-fetched idea after all.
NC State researchers devise new ways to invade your bloodstream
While schools in the ACC are certainly making noise on the hardwood, it seems that the Atlantic Coast Conference is also interested in shoving microbots all around your innards. Just days after a team from Georgia Tech envisioned a new internal method for monitoring blood pressure, research conducted at NC State is hoping to cram even more robotic creatures into deep, dark places within your body. A team led by Orlin Velev has discovered that "a simple electronic diode" could spark a new form of propulsion which could power robots and other diminutive devices from a distance. By exploiting "a phenomenon known as electro-osmosis," the diodes can push microscopic material through internal fluids "at speeds of several millimeters per second," which could allow cameras and medicines to reach critical locales that are presently isolated. Of course, there's still a good bit of work to be done, as the prototype device still has become substantially smaller before it will even fit in most of the tiny tubes within your skin, but it's looking more and more like we'll have nursebots shoving spinoffs of themselves into our beings before too long.[Via NewScientistTech]
Cheaper blue lasers on the way?
Whether the format war is over or not, one thing that would definitely get more buyers off the fence and owning more high definition players would be lower prices. Aonex Technologies and Kyma Technologies are the latest to announce they've found a better (and cheaper) way to pump out the blue laser diodes necessary in every Blu-ray and HD DVD player. Aonex claims its A-Sapph wafer technology improves on current sapphire based processes, enabling an increase in the number of chips per wafer and improving yields substantially. As fans of lasers in general, and not just in relation to HDTVs and lower prices, we're excited, but without even the hint of an expected release date it will probably be a while before these are ready for the market.
Ritek boasting ten-layer HD DVD / Blu-ray discs?
Forget single-layer media, that dual-layer stuff that was all the rage last year, and even the triple-layered flavor that got announced just days ago. Heck, even an eight-layer disc would be forced to bow down to the sure-to-be-outdone-soon ten-layer rendition supposedly crafted by Ritek. No sooner than we all celebrated the idea of a 51GB HD DVD, Ritek has reportedly "designed HD media with a full ten layers," not to mention the supposed three- and four-layer coasters it has laying around while working its way up. As if that weren't impressive enough, it also claims that this multi-layer process can be applied to both HD DVD and Blu-ray, a feat that Toshiba's recent creation can't quite compete with. Of course, Ritek officials were quick to point out that the "real barrier to this advancement is the lack of reader / writer laser diodes to support the additional layers," but if there really are 250GB BD discs just waiting to get spun, those lasers aren't too far behind.[Via Slashdot]
Sanyo's blue laser to speed up HD DVD / Blu-ray burning?
While Sony's certainly had its fair share of blue laser supply issues, and the current generation of HD DVD / Blu-ray burners are sluggish at best, it looks like the first step towards marginally acceptable write speeds to next generation formats has been taken. According to Nikkei, Sanyo has developed a blue laser diode which will speed up data access, and moreover, should be able to reach write speeds of "up to 6x for dual-layer discs." Similar to LG's combo unit, this diode also plays nice with both HD DVD and Blu-ray recorders, but there's no word if a hybrid writer using the laser is in our immediate future. Still, any progress towards harmony between the formats -- not to mention being able to burn a dual-layer Blu-ray disc in time for your next birthday -- is a step in the right direction, so we're expecting nothing less than a 6x burner to be hitting shelves sooner rather than later, Sanyo.
