Behind the scenes with the world's largest LED art project

SAN FRANCISCO--I'm standing behind Leo Villareal, watching the well-known artist calibrate settings in the software running on his screen. Each time he moves a slider, one of the world's largest art installations -- mounted on one of the world's most-famous landmarks -- changes in an instant.

It's a gorgeous evening on the Embarcadero, San Francisco's eastern waterfront, with the San Francisco-Oakland Bay Bridge dominating the landscape in front of us, and a near-full moon doing its best to overcome the typical evening fog cover. Lights from the city, and from Oakland on the other side of the bay reflect brilliantly in the water. And with just the most subtle adjustments in his custom-designed software, Villareal makes thousands of LEDs strung out over the 1.8 mile-long western span of the bridge almost instantaneously change what they're doing, and how they're interacting with each other. … Read more

Smart LED desk lamp is sensitive to your moods

The day of the single-purpose gadget is rapidly fading. You can't just have a phone that you use to talk to other people. It has to do 50 other things. You can't just have a desk lamp that lights up your desk. You have to have one that charges your phone and gives you mood lighting, too.

The Satechi Smart LED Desk Lamp tries to fit as much functionality in as it can. It charges smartphones and has a built-in timer to power it off. It's also very touchy-feely. It's controlled through a touch panel and has different lighting modes to fit your mood.… Read more

Getting your settings right for the big game

New TV? Old TV? New gear? Old gear? Are you sure all your settings are correct? Even if you're not planning on watching the big game, it's worth taking a moment to ensure you're getting the most out of your TV and assorted A/V gear.

Think of it like getting the oil changed on your car, or a visit to the dentist, except there's less chance of screaming and/or a tragic dental floss mishap.… Read more

NanoLight looks like an origami bulb of LEDs

It's a new era for lightbulbs. Incandescents are well on their way to being obsolete. Compact fluorescents are reigning champs, but LEDs are rising through the ranks, looking to challenge CFLs with advancing technology and falling prices. As fast as the tech changes, we're still pretty hooked on the old-school incandescent shape. We still want our bulbs.

The NanoLight Kickstarter project wants to give us LEDs without sacrificing the traditional bulb shape and ability to shine light in all directions. The result is a bulb that looks like it was designed by a Cubist painter. The makers claim it is the most energy-efficient light bulb in the world.… Read more

Get an Asus 24-inch LED monitor for $149.99 shipped

You know the expression, "Go big or go home"? I say go big in your home! See what I did there? (I know. Terrible. You'll have to forgive me; it's early and I'm pre-coffee.)

For a limited time, Amazon has the Asus VE247H 24-inch LED monitor for $149.99 shipped. That's after redeeming at $20 mail-in rebate (PDF).

That rebate will come in the form of an American Express Prepaid Reward Card, which is more or less as good as cash. Don't like rebates? That's cool -- I'll see you back … Read more

The 2013 TVs of CES are bigger and smarter, but what about the picture?

Will flat-panel TV picture quality get even better in 2013?

I'm guessing "Yes" in the case of the Best of CES nominee Panasonic TC-PZT60 and the re-engineered Samsung UNF8500, very likely the two best-performing TVs of 2013 under $10,000.

But those two are hardly the TV hardware poster children of the 2013 Consumer Electronics Show, where all the headlines touted expensive 4K and OLED sets -- still stupid and chronically under-delivered, respectively -- as well as new gadgetry of questionable usefulness. Finger-gesture control, anyone?

I got a chance to see both the Panasonic and the Samsung … Read more

LG's LA6900 TVs to feature voice control, Magic Motion remote

LAS VEGAS--If you're looking for a midrange television, then one of the LG televisions to consider in 2013 is the LA6900 series, which will come in three sizes: 50-inch, 55-inch, and 60-inch.

Half of LG's range now includes the "Cinema Screen" design the company debuted last year with its impossibly thin bezels and the LA6900 is also one of these.

The LA6900 boasts "natural language" voice control via the new Magic Motion remote, which means you don't have to utter some robotic command before looking for what you want. Good if it works, … Read more

Panasonic Web site reveals preorder pricing on some 2013 TVs

LAS VEGAS--Pricing information is usually hard to come by at CES in January. Manufacturers have just debuted their newest products, and final suggested retail prices are usually subject to some jockeying before the products launch over the next few months.

That's why I was surprised when my colleague Matthew Moskovciak sent me a message saying that Panasonic's official site, shop.panasonic.com, was showing pricing and other details for TVs the company had just announced this morning.

Most of the company's TV series are listed on the site now, with the exception of the lowest-end X60 and … Read more

Panasonic sticks with plasma-heavy TV lineup

LAS VEGAS--There are still going to be three makers of plasma TVs in 2013 -- LG, Samsung, and Panasonic -- but the only one going all-out for the display technology is Panasonic.

The company has announced five full series of plasma TVs, and here they are in a nutshell.

TC-PZT60 series (65 and 60 inches) Panasonic's 2013 flagship promises "Beyond the Reference" picture quality, with an all-new Studio Master panel that has the thinnest gas layer yet, which the company says will remove dim and double images. There's a newly developed red phosphor, faster switching than … Read more

Sharp updates AQUOS lineup, intros SmartCentral interface

LAS VEGAS--The mantra for Sharp's new AQUOS LED TV line unveiled at CES 2013 on Monday morning might be as simple as this: bigger and better.

The bigger quality will be obvious from the get-go with 21 new displays in the 60-, 70-, 80-, and 90-inch LED TVs in the AQUOS portfolio.

But the better comes in the form of upgraded display quality as well as more digital content and connectivity.

With the 80-inch class displays in particular, Sharp has added a new layer dubbed "Super Bright," which is the combination of an intelligent contrast engine with … Read more
