Morph a McDonald's iZ toy into an IR repeater
Apparently this is the season to give IR-less, inanimate objects a bit of infrared love, as we've now got yet another IR installation duty for you handle once you've mastered the chore of getting the connectivity in your PlayStation 3. For those mums and pops who frequent McDonald's all too frequently, you've probably got a satisfactory stash of iZ toys laying around like landmines in the kitchen floor. If you've already got a (partial) multiroom IR channeling setup going, there's always the need for more coverage, so that's where the relatively useless "orange iZ" comes in, along with an IR receiver, soldering gun, and a dash of DIY prowess. This engineering dad cracked open the critter, carefully inserted the repeater, and made sure to clean up the mess by routing the cables through a rear opening, producing an impressively clean result. So if you're looking to make something worthwhile out of those otherwise ineffectual Happy Meal toys, be sure to hit the read link for all your instructions, and click on through for the repeatin' in action.[Via MAKE]
Use a universal remote with PS3
Universal remote fans -- after trying a Logitech Harmony remote, we can't go back to one-remote-per-device -- will run into trouble on the PS3; its standard remote works over Bluetooth, not IR. So the PS3 remote gains the ability to work in other rooms, but it loses the universal appeal of IR blasting. Remote Central documents the process of adding an old PS2 IR receiver so that you can use that PS2 remote -- or a universal model -- with the PS3.The steps seems simple enough; all it takes is the PS2 IR receiver dongle and the PS2-to-PS3 gamepad adapter. The translation loses some of the functionality of the PS2 remote -- 14 common commands work, but 35 don't -- but it may be enough to watch Blue-ray movies with a universal remote.See also: Universal remotist finds fault with PS3, console lacks IR port[Via Engadget]
Control your PlayStation 3 with IR
Ok, so the PS3 certainly has its strengths (like the built in Blu-ray player, for instance), but there's definitely a few gripes following it around as well. A (very understandable) complaint from AV freaks has been how the home-theater-centric console strangely lacks an IR receiver, and instead, Sony opted to offer up its proprietary Bluetooth remote to control the BD movie action from afar. Those looking to dictate your PS3 with that (presumably costly) universal IR remote, take heart, as the clever folks at Remote Central have whipped up a way to add infrared functionality to your IR-less machine. Aside from a PlayStation 3 and a desire to further integrate it into your home theater setup, you'll need a PSX/PS2 Controller-to-USB adapter as well as an original Sony DVD remote for the PS2 (model SCPH-10172) with external IR receiver (model SCPH-10160). Of course, the aforementioned remote should prove trickiest to find, as the current models lack that crucial external receiver to account for the built-in version found in the slim PS2 units. By connecting the external IR receiver to the adapter box, and then plugging the resulting combination into a USB port, you've created an unsightly way to talk to your PS3 via infrared. So if you've got integration on the brain, or just don't feel like shelling out the funds for that newfangled Bluetooth remote, be sure to hit the read link for the full skinny, and give yourself something productive to do over the relaxing holiday vacation.[Via CEPro]
Researchers develop metamaterial with negative refractive index
We've got next-to-invisible objects and cameras with ridiculously large sensors, and thanks to a team of brilliant researchers over in Germany, now we've got "an exotic material with a negative refractive index for visible light." Gunnar Dolling and his colleagues at the University of Karlsruhe in Germany have created a metamaterial with layers of silver sandwiching a thin sliver of nonconducting magnesium fluoride on a glass sheet, and once an array of square holes were etched in, his tests showed that the "structure had a negative refractive index of -0.6 for light with a wavelength of 780-nanometers," besting the previous record of 1,400-nanometers. While the scientific babble may not mean much to you, the long and short of it is that this discovery could "lead to further breakthroughs in invisibility cloaks, which could hide objects from the human eye" and make escaping your troubles quite a bit easier. Moreover, the technology could be used in "superlenses" to see details "finer than the wavelength of visible light," but Dolling is reportedly more interested in studying the effects of his discovery than attempting to build any mystical devices, which is probably for the good of mankind, anyway.[Via Slashdot]
Philips patents razor light technology to zap hair growth
While most folks aren't exactly fond of going bald on their noggin, eliminating the pesky hair on faces and legs doesn't sound half bad. Aside from the gazillion topical treatments scams available at your local Wally World, there's always the uber-expensive "laser hair removal" option, but Philips seems to think it has a less costly, less intrusive solution. The firm has recently patented razor light technology, which utilizes "low doses of electromagnetic radiation" to kick active follicles into the dormant catagen phase. By sending pulses "between 1 and 100 milliseconds" apart just above the skin, it offers up a relatively safe, easy, and (hopefully) pain free experience to putting a halt to shaving every other day (or more). Obviously, the method isn't aimed at immediate hair removal, as plans are to implement numerous treatments over "two week intervals," but it could slowly eliminate the regrowth of hair once treated. So while we're not exactly sure when you'll be replacing that bag of disposables with a newfangled light gun, a little help in the hygiene department is never a bad thing.[Via NewScientistTech]
TV remotes demystify Wii sensor bar
It seems that the Wii's sensor bar isn't entirely necessary to use the Wii remote's pointer functionality. An intrepid Wii user has posted an online video showing intermittent pointer reception using two TV remote controls in place of the sensor bar.Apparently the Wii sensor bar is actually a transmitter for a dual IR signal that gets triangulated by the Wii remote, not a receiver for a signal that comes from the remote. This revelation would seem to suggest that any correctly positioned, consistent dual IR source can be used in place of the official Nintendo provided sensor bar. With this information in hand, how long will it be until we see hackers rigging up their own custom sensor technology?
Slingbox PRO has a mysterious built-in infrared receiver
Jimbo, an intrepid member of the Sling Community, recently tore open his Slingbox PRO to document the chips inside, and in the process seems to have discovered an infrared receiver hidden away behind the Sling logo. No one's quite sure what this is for, but Dave Zatz, an Engadget special correspondent, is speculating that this may give the PRO some "SlingCatcher functionality" -- making it possible to watch a remote Sling feed on a TV -- or that it could possibly be used to display additional information somewhat like the upcoming Wii channels. Zatz has put in an inquiry to Sling and will keep all of us posted. [Via Zatz Not Funny]
Wal-Mart to use infrared to track shoppers / promotions
As if its insanely coordinated logistics system, biometric payment system, and (potential) RFID shelving weren't eerie enough, America's largest retailer is taking consumer voyeurism one step further with the use of infrared technology. In an apparent attempt to avoid the taboo "RFID" flavor of intrusion, Wal-Mart is hoping to sneak an IR system into its stores to gauge the effectiveness (and elicit more advertising dollars, of course) of its various promotions. Dubbed Prism, the arguably dodgy system was crafted by Coca-Cola, Kelloggs, Kroger, Procter & Gamble, Walgreens, and Disney in order to "track shoppers' movements around the store" and correlate them with actual sales in order to judge display effectiveness. The consortium of firms has coaxed the corporate giant to install a trial system in ten of its SuperCenters, with a much broader rollout expected to follow soon; so when making that mad dash to the Tickle Me Elmo eXtreme (or bathroom supplies) section, just remember that Big Brother could be keenly watching.[Via TechDirt]
HTC: Music - yay! Infrared - nay. Symbian - maybe.
In a not-so shocking development, handset trendsetter HTC is, according to president / CEO Peter Chou, considering making their devices more music friendly by increasing internal flash memory at the same time as cutting some fat, namely IR. (And really, how often do you use IR on a phone with USB and Bluetooth?) Most interesting, however, was Chou's statement that if an operator or reseller were to make it worth their while, HTC wouldn't have a problem getting in the Symbian device business: "We're not limited. We're not Microsoft, we can do anything." Unfortunately that hasn't yet come to pass, but it's not like an ODM like HTC shouldn't have a price when it comes to developing hardware for other platforms. We'd absolutely welcome some variety to the hardware running world's most prolific phone OS, and who knows, maybe sometime soon we'll see an HTC e61 killer.[Via the::unwired]
Control your IR devices via SMS
As the site clearly indicates, "The purpose of this circuit is to make the human life better and easier," and we couldn't agree more. If you've got an ancient Ericsson lying around that would otherwise be ready for the recycle bin, this circuit gives your faithful friend a new lease on life as an SMS-actuated IR sender capable of controlling up to eight devices, depending on how you opt to build it. A simple 8-digit text message to the phone is all it takes to send the appropriate ON or OFF signals, and as an added bonus, the author shows you how to wire the phone directly into the circuit so a battery's no longer required. A better and easier human life, indeed.[Via Make]
Virtual Piano for Chopin on the go
It was bound to happen sooner or later. Ever since those keyboards of the typing variety got all virtual on us, we knew the instrument version would go infrared and turn our rhythmic table tapping into beautiful music. The new device, from Digital Information Development, operates -- and looks -- quite like that Bluetooth version from iTech, 'cept there's a speaker in this unit to pump the tunes you're generating. Though there's just a 25-key keyboard in this version, DID is promising an 88-key "grand piano" unit, and even some sort of weighted notes (we'll believe it when we see it). This first iteration includes piano, organ, pipe organ and harpsichord sounds, and should cost around 15,000 yen ($130 USD) when it hits stores in Japan this November.[Via Pink Tentacle]
"3rd-i" cam for spyin' on the go
There are undoubtedly less proprietary ways to go about doing this, but if you're looking for a quick, painless way to get a PC-free camera feed to your phone, a British operation by the name of 3rd-i reckons they have the answer. The concept is simple enough: take your garden-variety video cam, strap on a GPRS modem, and call it good for £199 ($370). Besides accessing live video and up to 30 days of archived footage via pretty much any Java MIDP 1.0- or 2.0-enabled phone, the unit can be set up to immediately text you upon detecting motion. Not bad -- in fact, we'd strongly consider using 3rd-i's cams to secure the Engadgetmobile, but the dual band 900 / 1800 support just doesn't cut it in these parts.[Via Crowdedbrain]
Researchers develop cheap, effective nanoparticle infrared detector
MIT's venerable Technology Review reports that a team of Canadian researchers led by Edward Sargent have devised a highly sensitive infrared chip that could potentially make night-vision goggles and other imaging devices both cheaper and more effective by using, what else, nanotechnology. The system involves spinning a glass slide or silicon chip to evenly coat it with a special solution of conducting nanoparticles called quantum dots -- something that can be done for as little as $17 per square meter, Sargent says. With the solution, the chip is able to pick up both the near and short-wave infrared (SWIR) bands, allowing for accurate night vision even in cloudy conditions. What's more, Sargent says the technology could also be applied to medical devices, since SWIR light can apparently easily pass through tissue at no risk to the patient. Your guess is as good as ours as to when we'll actually see any of this outside of the lab, but with the promise of higher yields than traditional fabrication processes, there's definitely an incentive to push this tech out the door.[Via Medgadget]
Found Footage: Use iSight as an IR detector
Here's a useful tip for those that want to test the batteries of their Frontrow remote, or any IR remote for that matter. Use your iSight! Just fire up Photo Booth (or a test video window in iChat), aim the remote at the lens and press a button. The iSight can detect the infrared light just like other video cameras.
How-To: IR Remote Control your Computer
For today's how-to we spent some time rummaging around in our parts box to build a serial IR remote interface for our PC. We took a few pieces from various designs to come up our own, built specifically to work with WinLirc or LIRC; it can transmit and recieve IR signals, just imagine the possibilities.
Opticon-toting driver gets $50 fine for changing traffic light
We hate waiting for traffic lights to change as much the next driver (or pedestrian -- we have to cross streets, too, you know), but we doubt we'd ever try to take things into our own hands like Jason Niccum of Longmont, Colorado, did. Niccum picked up an Opticon -- an infrared light used by firefighters and other emergency responders to trigger traffic signals -- on eBay for about $100, and has been using it to cut his commuting time. That is, was using it, until local cops busted him after they noticed a consistent pattern of traffic-light disruptions at certain intersections. They nailed Niccum, and the town now plans to change the frequency used by traffic lights to block unauthorized signals (until, that is, someone comes out with a next-gen model). Niccum, despite getting stuck with a $50 fine, isn't exactly remorseful. "I guess in the two years I had it, that thing paid for itself," he told a local newspaper.
