Philip's Interactive LED Tattoos Could Be the Future of Body Art


Ah, human progress. It's long been possible to get drunk with your friends and make a permanent mistake on your body on spring break in Mexico, but soon you'll be able to do it electronically, too. That's right, we are entering the era of the LED tattoo.

Researchers at the University of Pennsylvania have been developing micro-thin, flexible, silicon electronics that have already been successfully implanted under the skin of mice without any harm. These devices can conform to the body's shape without causing any irritation or interfering with its normal physiological processes. (The silk is eventually dissolved and absorbed by the body.)

Gift Guide: Shift and Ctrl Key Lights


Shift and Ctrl Key Lights
(Style-o-Phile, Under $50)

An interesting piece of lighting has the ability to totally transform the ambience of a space, as well as bring other design elements into frame. The Shift and Ctrl Key Lights ($19.90 each) are an inexpensive, novel, and still touchingly geeky solution. The oversize keys come in both yellow and white (we like the cool minimalist look of the white) and are lit with energy-saving LEDs. Perfect for students, or even livening up an office or home workspace, these lights have just the right amount of whimsy without being overly gimmicky. The only downside is that Alt and Delete lights are not yet available to compliment Ctrl for the ultimate (end) task lamp.

Cutting-Edge, Eco-Friendly LED TV for Less Than $2,200?


A reader writes: I need a good TV for my living room, and I've decided that LCD, particularly LED, is the way to go. I've heard that some plasmas can look better than LCDs, so I definitely want good video quality, but I heard they use up a lot of energy and I don't want to break the bank if I can avoid it. Also, I'd like something that doesn't use up too much power. Please... just tell me what to get!


What up, reader? Indeed, the Plasma vs. LCD conflict is a tough one, as plasma does traditionally provide better black levels, which can translate to superior contrast between dark and light onscreen, especially valuable when watching high-definition movies now in the Blu-ray era.

The good news is that LCDs are continuing to evolve, with the switch to energy-saving LEDs (light-emitting diodes) as their light source (versus more common cold cathode fluorescent lamps, if you want to get technical). The Next Big Thing in energy-efficient televisions is local dimming LED, which can make specific areas of the screen lighter or darker depending upon the picture being displayed. The improvement can be absolutely stunning, imparting more drastic blacks and a much-needed boost to the dynamic contrast ratio, rated at a mind-boggling 2,000,000:1. Unfortunately, a lot of these LED TVs are pricey, but we've found one from good ol' bang-for-the-buck Vizio.

LED Eyelashes Brighten Eyes... Unnaturally

Down in the dumps? Got a bad case of the Recession blues? Pints of Chunky Monkey and Gilmore Girls reruns not doing the trick anymore? Don't worry, ladies, a newly released cosmetic device may finally bring back that certain "twinkle" in your eye.

Designer Soomi Park's latest eyelash accessory features LED technology that brighten up the eyes of the wearer. The coolest thing, besides being able to land an airplane with the bat of a lash, is that the lashes are also connected to a tilt sensor, which turns the lights off and on with each head movement. According to the designer, the lashes were created as "a product that speaks to many Asian women's desire for bigger eyes." And how!

LED Lights Let You Pimp Out Your Couch, Neon-Style

Remember when everyone installed those neon lights underneath their cars, like in 'The Fast and The Furious?' We thought that trend had died out like Paul Walker's acting career.

Now, thanks to LIT's LED lighting kit, you can relive those days in the comfort of your own home. These LED tubes can be installed around or under just about any piece of furniture in your house, giving it that sci-fi or street racing feel you've been looking for. According to DVICE, the basic kit costs $210 and includes a 37-inch adjustable LED tube, a remote control, and a power supply. If you just can't get enough of that neon glow, additional tubes are available for $75 to $88. You can choose just about any color of the rainbow with the remote, or you can set the lights to cycle through each color so you'll never get bored with just one.

U2 Takes Massive Transforming Screen on Tour

Twenty years ago, as one of the world's biggest rock bands, U2 could appease their fans by simply playing "Where the Streets Have No Name" on a building rooftop. Twenty years later, U2 is still huge, and their live performance has evolved into a gargantuan show of lights, screens, and over-the-top stage props. Don't believe us? Check out the band's expanding screen currently in use on the U2 360° tour.

The display, made by Hoberman Associates and Innovative Designs (also responsible for the mammoth screen used on U2's PopMart tour), contains 888 individual screens for a total of 500,000 LED pixels. By using hundreds of small screens that expand and contract in their distance to one another, the screen can literally change its shape. And because the space between each screen is adjustable, it can also take on a transparent quality that allows fans to see images projected in 360 degrees without blocking the view of the band. To see the monstrous screen in action, check out the video here. [From: Core77]

Tesla Model S Now Official


After a brief period of unofficial officialness yesterday morning, Tesla has rolled out the Model S to a sea of eager photographers. The company's also revealed specs for the EV: this seven-seater can go from 0 to 60 MPH in 5.6 seconds, boasts a top speed of 120 MPH, features a dashboard display and a 17-inch main touchscreen monitor. It's fully 3G capable, sports HD and satellite radio, uses LED and neon exterior lights, smart-key power, and push button gear selector. While that $49,900 base price will get you a battery that's good for 160 miles per charge, 230-mile and 300-mile range packs will be available. On a 220V outlet, the company says it'll charge in four hours with a 45 minute "QuickCharge" option, and you should be able to swap batteries if necessary in under 8 minutes. Excited? Find a way to control yourself, this baby isn't going into production in Q3 2011. Check out a brief glimpse of the interior after the break.

Yankee Stadium Goes Big With New Jumbotron


With spring training now in full gear and the regular season just around the corner, baseball fans have plenty of reasons to look forward to the 2009 season, 3D-enhanced baseball cards being among them. Although New York Yankees fans had to say goodbye to the historic Yankee Stadium last year, they'll be pleased to find one of the largest TV screens in the world installed next door at the new $1.3 billion Yankee Stadium.

The Mitsubishi Diamond Vision LED display spans a massive 6,000 square feet. The huge, high-definition outdoor screen, made up of 8,601,600 LEDs, will be able to pump out four separate video feeds at a time, and can even do live picture-in-picture. Wired also reports that the new stadium will contain over 1,400 other video screens, so you won't have to worry about missing a play if you get the snack bar munchies or need to run to the bathroom. Fans should have no problem seeing the towering 60-foot-tall screen, although the action on the field might be harder to discern (especially for those who can't afford to pay $600 for a decent seat).

New Philips LED Light Bulb Lasts for 45,000 hours


Philips has been hitting us with some out-there lighting concepts lately, but the company's Master LED light bulb is actually already on sale in Europe and is set to brighten up Stateside lives around July. The 40W-equivalent bulbs should run between $50 and $70, and expected lifetime is set at 45,000 hours -- just slightly more than a CFL's 10,000 or a standard bulb's 750 hours. The Master is certainly a damn sight nicer looking than the other mutant LED bulbs we've seen, but we'll see if consumers are ready to jump on another more-expensive-upfront lighting tech so soon after CFLs have hit the mainstream.

LED Light Bulbs That Last 60 Years to Get Cheaper

Super-Efficient LED Bulbs to Get Cheaper
Those old-school incandescent bulbs you grew up with are on their way out, deemed too inefficient for a continued life in today's eco-friendly society. But their replacements, compact flourescent (CFL), have their own share of issues. Some people find that the next-gen bulbs give them headaches, and since each one contains a bit of mercury they aren't exactly green themselves. For that reason, many have seen LEDs as a possible replacement, but they have their issues, too, primary among them being cost. That could change thanks to a British professor's newest tech, which could make the bulbs considerably cheaper.

LEDs are small and don't give off much light, but they last for literally decades (like, 60 years) and give off virtually no heat, making them three times more efficient than the twisty CFL bulbs. Professor Colin Humphreys at Cambridge University has come up with a way to make them far cheaper than normal, creating a more efficient way to produce gallium nitride, a material required for the production of LEDs. His discovery could pave the way to LED bulbs that cost less than $5 a pop. However, we're still at least a few years away before these could go into mass production, meaning you're going to have to keep hitting the Asprin or guiltily using your old incandescent bulbs.

LG Debuting World's Slimmest LED-backlit LCD TV at CES


Not content with just making soap opera hair look like watery strands of gold, LG is also planning to trump last year's round of ultrathin LCD TVs by bringing the planet's slimmest LED-backlit LCD TV to Las Vegas. Expected to garner fingerprints from every nationality at CES 2009, the LH95 will check in at just 24.8-millimeters thick (0.976-inches) and boast a 2,000,000:1 dynamic contrast ratio and the outfit's 240Hz TrueMotion Drive dejudder technology. No word on a price or release date (or panel size, oddly enough), but hopefully we'll find out more in just under a fortnight.

Speed Bump Flattens Out For Slower Drivers


Speed bumps are supposed to punish the speeders and minimally offend those abiding by the legal limits. But, as all drivers know, crossing the things sucks at any speed and, regardless of how brightly painted they are, they're easy to miss until you're finding out the hard way just what kind of suspension travel your ride offers. A smarter bump from designers Jae-yun Kim and Jong-Su Lee could be the answer. Unlike the ones we've covered in the past, this one stays up all the time, using a small damper inside to flatten out when a car drives over it at low speed. The higher force applied by a faster car would prevent the bump from lowering and, presumably, ruin that dastardly speeder's day. The things are also festooned with LEDs on the front, back, and sides, which might just mean you'd be able to see this one in time to save your dubs from destruction. [Via Techie Diva]

German Scientists Think LEDs Are the New Botox


All of us here are young, beautiful, and vigorous, but we understand that time is not always as kind to everyone else as it has been to us -- that's why we're giving you the heads up that German scientists claim that they were able to reduce wrinkles by subjecting a test subject's skin to regular ol' LED lights daily over a period of several months. It seems that at a certain intensity the light dives into skin tissue and alters the molecular structure of water that would otherwise immobilize elastin, a protein that keeps skin healthy and, y'know, elastic. The researchers believe the tech can be "converted to deep body rejuvenation programs," which we assume entails more than just taping our faces to our LED-backlit screens -- but we'll try it just in case.
