Flatsun: 60,000 LEDs Simulate the Sun

I didn’t think that anything could accurately emulate theSsun, but that didn’t stop Rafael Lozano-Hemmer from trying, as he used 60,000 LEDs to recreate some solar magic – albeit without the intense light and heat of the actual Sun.

At 4.5 feet in diameter, Flatsun is still a billion times smaller than the real Sun. Rafael used mathematical equations to position the LEDs in the large circular panel that mimics the sun’s never-ending movements. Custom panels inside the larger structure hold the red and yellow LEDs, which give off that eerie, but fascinating solar glow.

As people walk by Flatsun, it uses a video camera to responds to their movements. If the room is crowded, it’s turbulent, as if there were solar flares on Flatsun‘s surface. As the room empties, the installation slows down and finally shuts down completely.

Interactive LED Cube: Rubik’s Cube 2.0

Thanks to touchscreens and other input sensors, we’re finding more ways to integrate physical movement in electronic entertainment. The Princip Interactive LED Futuro Cube is another example. Its sensors work with the embedded LEDs to amuse – or frustrate – you in all sorts of ways.

princip interactive led futuro cube

The Future Cube has multi-axis accelerometers, 56 LEDs and a speaker. The accelerometers enable it to detect gravity, motion and tapping, the LEDs are there to, well, light up, and the cube provides feedback, tutorials and score through the speaker. The cube has 12 game modes, including Gravity Puzzle (similar to Rubik’s Cube but with tapping instead of rotating!), Snake (it slithers through all six sides!) and Cubris (Tetris, except it’s way more confusing!)

Here’s a quick demo of Gravity Puzzle:

Did you understand what was happening in that last video? Neither did I. All the more reason to get one of these toys. You can order the Princip Interactive LED Futuro Cube from ThinkGeek for $100 (USD).

Fireflies’ bumpy abdomens may lead to brighter LEDs

Fireflies' bumpy abdomens may lead to brighter LEDs

Scientists who evidently spend too much time with fireflies have managed to put all that bug-watching to good use: developing brighter LEDs. One problem with that tech is that a lot of the light gets reflected back into the device due to the way photons travel through LED materials, causing them to lose efficiency. But researchers from the University of Namur in Belgium noticed that the misshapen abdominal scales on fireflies act to prevent reflection, letting more light from the luminous insect’s “lantern” shine out. Scientists in Canada took it a step further by doping standard gallium-nitride LEDs with a similar material, and found that light transmission increased by 55 percent. They claimed that such a process could be done to “nearly every commercially available LED,” which could one day bring insect-inspired energy savings to commercial products.

LED Ice Cubes Detect Alcohol To Warn You Of Over-drinking

LED ice cube drunk 640x214 LED Ice Cubes Detect Alcohol To Warn You Of Over drinking

Drinking can be quite the dangerous activity when you’ve lost count of how many drinks you’ve had. Sure – pounding down drink after drink can be fun, but the results of those drinks can make for one bummer of an evening or following morning if you’ve lost count. We know you can have your designated driver keep tabs on how many drinks you’ve had, but if they’re sour about not being able to drink for the night, then they can certainly screw you over. You need the power of LEDs to help you know when to stop.

MIT Media Lab researcher Dhairya Dand created the LED ice cubes after a night of alcoholic drinks resulted in a blackout that put him in the hospital. The LED ice cubes detect alcohol and flashes colors based on the amount of drinks you’ve had. They track the number of sips you take and total time spent drinking in order to predict when the user may be intoxicated.

The LED ice cubes may make you look like an alcoholic, but they flash in sync with ambient music and sounds, which pretty much makes your cup a “party cup.” Three colors will show – green, orange and red – to tell the user just how drunk they are. The LED ice cubs can also be used to detect when a user has gone beyond its red level, which results in a text message warning a friend of your drunken escapades.

Study On Fireflies Results In Brighter LEDs

 Study On Fireflies Results In Brighter LEDs

CES is slowly coming to an end, but we’ve heard of a lot of new LEDs coming out this year from multiple manufacturers. LEDs look incredible, but they can look even more incredible thanks to fireflies.

A study was conducted by the University of Namur in Belgium that took a look at how exactly fireflies create their light in order to modify existing LEDs to run more efficiently. During the study, they identified a pattern in the scales of the Photuris firefly that boosted the amount of light that is created in its lantern, which is an organ located on its abdomen used to attract females. The way the Photuris firefly has its scales were in such a way, that it was able to produce more light from its lantern.

Scientists studied the scales of the Photuris and attempted to mimic it by using a laser to etch a profile similar to the scales on the Photuris onto an LED bulb. The result of the test allowed the LED bulb to emit approximately 55 percent more light than it had before.

NEC revamps its MultiSync lineup with new 24-inch IPS monitor

NEC revamps its MultiSync lineup with new 24inch IPS monitor

NEC’s MultiSync monitor lineup is well-known for offering a slew of versatile choices — as such, this year’s CES isn’t too bad a time for the Lavie creator to introduce a new member of the family. The newly announced 24-inch LED EA244WMi looks pretty good on paper, boasting a 1920 x 1200 resolution with IPS technology and a 16:10 aspect ratio, plus there’s also built-in speakers four USB 2.0 ports, HDMI, DVI-D, VGA and, similar to that EA231WMi, a DisplayPort. Naturally, NEC has added plenty of its own customization options to the rather adjustable monitor, including ControlSync to help with multi-screen setups, ECO Mode and a “smart” sensing feature which adjusts depending on “ambient light and human sensors.” The EA244WMi will go on sale later this month for $379; in the meantime, we have a press shot gallery after the break to hold you over until the monitor eventually hits shelves.

Samsung reveals full Ultra HD, OLED and Smart TV lineup at CES 2013

Samsung is going big with TVs at CES 2013: big in screen size, and big in resolution, with the record-setting 85-inch Ultra HD UN85S9000 at the top of a new HDTV line-up that also includes OLED models. The largest UHD set we’ve seen so-far, the Samsung UN85S9000 delivers four times the resolution of an 1080p Full HD TV, as well as 3.2-channels of 120W sound and all of the Smart TV functionality you’d hope for. Meanwhile, Samsung has refined its 55-inch OLED monster, with a special new 3D feature catering for two people wanting to watch different things.

Inside the 85-inch behemoth, there’s not only 2D to 3D conversion, but HD to UHD conversion, along with Smart TV features like streaming, apps, motion control, and voice control. It’s all powered by an A15 quadcore 1.35GHz processor, something you’d more commonly expect to find in a high-end phone or tablet, as well as support for the Smart Evolution Kit which will add new features further down the line. However, it’s likely to unusual easel-style mount which will grab the most attention (at least before the screen gets powered on).

samsung_un85s9000_85-inch

Samsung has been pushing OLED as the Next Big Thing in TV technology, and the 55-inch KN55F9500 Real OLED TV is the latest iteration of the company’s vision. Built around the same quadcore processor as the UN85S9000, and with all the Smart TV functionality including voice control and streaming media, the OLED set is also the first to feature Samsung Multi-View, which uses 3D display technology to show two viewers (each wearing active 3D glasses) different content simultaneously.

That works in 2D and 3D, and even delivers stereo audio to the viewer thanks to tiny speakers built into the glasses. There’s also Smart Evolution Kit Connector support, and a new version of Motion Control gesture recognition that can better track hands held at up to 45-degree angles.

Most regular buyers will head to Samsung’s LED 8000 Series or LED 7000 Series sets, of course, also new for CES 2013. The 60-inch UN60F8000 borrows the 1.35GHz quadcore A15 of its bigger brother, along with the same Smart TV functionality, motion and voice control, and streaming from the web and mobile devices. It also gets Micro Dimming Ultimate for more precise control of the LED backlighting, and De-Jagging Pro for cleaner edges. 3D crosstalk is down too, by 30-percent, and even web content is meant to look better, with text and image processing applied to the TV’s browser.

As for the 60-inch UN60F7500, that sticks with the same quadcore processor but does without the Micro Dimming Ultimate technology; otherwise, it’s the same mixture of De-Jagging Pro smoothing, Precision Black intelligent contrast control, and improved 3D crosstalk prevention. Both the 8000 and 7000 Series support the Evolution Kit.

Finally, there’s a new plasma set on offer, the Samsung Plasma 8500 Series, with the 64-inch PN64F8500 promising the darkest blacks and brightest pictures ever from a plasma TV. It shares the processor and Smart TV features as its LED brethren, but adds Deep Black Algorithm II and Real Black Pro for a combination of computer-controlled white light reduction – keeping those black areas inky – as well as 2.5x brighter whites when necessary. There’s also a new “nanocarbon compound” used to reduce stray ambient light.

Samsung doesn’t have availability or pricing details for either the UN85S9000 or the KN55F9500, though neither is likely to be cheap. The LED 8000 Series will ship in the first half of 2013, along with the LED 7000 Series, and the Plasma 8500 Series.

Samsung unveils 85-inch S9 UHD TV, 110-inch model to follow later this year

Samsung unveils 85inch S9 UHD TV, 110inch model to follow later this year

At CES 2013, it is apparently a must for mainstream HDTV manufacturers to bring a 4K television and as a market leader, Samsung is no different. So what does the mighty S9 UHD TV bring to the table? At 85-inches, it claims a size that’s one inch beyond the competition, and features a crazy “Timeless Gallery” frame design that Samsung says “showcases the juxtaposition of a minimalist concept with such a large display.” Even after getting a firsthand look at it we’re still not sure how to interpret its odd stance, but after promising an “unprecedented new shape” we guess this… had to be it?

No matter how it’s propped up, it’s still high end all the way, with “Precision Black Pro” display tech for an extremely high contrast ratio, 2.2 channel audio and integrated scaler to make your 1080p videos viewable at the higher res. Naturally, you can also count on all of Samsung’s 2013 smart TV features with quad-core processor, voice and gesture control and apps making an appearance. There’s no word on pricing or ship date, but Samsung is promising 95- and even 110-inch sizes before the year is out — check below for more pics in the gallery and details from the press release.

Samsung 2013 LCDs and plasmas revealed: quad core CPU, new menus and more

DNP Samsung 2013 LCDs and plasmas

As a leading manufacturer of HDTVs, Samsung has predictably returned to CES with a heaping armful of new displays of both the plasma and LCD variety. There are many common factors across the higher end models, including new A15 quad-core 1.35GHz CPUs that claim a 3.6x speed boost over last year’s dual cores. That extra horsepower isn’t being wasted either, as this year’s sets are the first to decode HEVC video, and also feature improved voice control with natural voice commands, better recognition of gestures with support for two-handed gestures, pinch to zoom and more.

All are due during the first half of 2013 and include Samsung’s AllShare DLNA client, as well as the S-Recommendation lists to help you find things to watch. The F8500 series plasma features brighter whites and blacker blacks as well as other picture quality enhancements compared to years past and is available in three sizes; 51, 60 and 64 inches. The flagship F7500 LED 3D TV is available in 46, 55 and 60-inches, while its bigger brother, the F8000 series, does what it can do and adds a built-in camera and mic; and is available in five sizes ranging up to 75-inches.

Like the higher end 2012 Samsung HDTVs, the new models also feature a Smart Evolution slot for future expansion. Owners of last year’s sets will be able to pick up a Smart Evolution Kit and add the new features of this years models without replacing their TV.
