Maker and teacher Bill Porter had a very important task ahead of him. He had to impress more than 100 eighth graders at a STEM camp. He had already wowed them with an LED lab coat and an 8-bit tie, but they wanted to know what was next. So Porter invented the Tetris tie, a glowing LED tribute to the classic falling-blocks game.

It took Porter about four hours to get the working prototype up and running. The tie uses 80 LED pixels powered by a DigiSpark microcontroller. It cost about $50 in materials.

Showing ingenuity and the ability to work with parts on hand, Porter fashioned the tie itself from two pieces of card stock and a cheap clip-on tie. The clip-on feature is the nerdy icing on the geeky make-cake. "I plan to revisit the design and embed the strips directly into a fabric tie for long-term use," Porter writes.… Read more

Recently, CNET started measuring input lag. This is the amount of time it takes for a TV or projector to produce an image. In the worse case, excessive input lag can cause lip sync issues. In most cases, it can lead to worse performance with certain games.

Since the article hit, there's been a surge of people ridiculing certain displays as "unacceptable" due to their input lag issues.

Hang on -- unacceptable? Just how important is input lag, anyway?… Read more

Recently we took a poll where we asked "What's stopping you from getting a plasma?" A majority of voters rebuked my premise, picking "I love my plasma." The other responses were fairly evenly split among the choices.

However, there was a surprisingly common reason given in the comments that baffled me, and it's so bizarre it's clearly worth debunking, or at least shining the light on the facts.

So how much do TVs weigh?… Read more

Today's HDTVs are packed with Smart TV suites, fancy picture processing, and other extras that add functionality and/or affect picture quality. For a serious gamer, none of that matters compared to the responsiveness of the TV, and often the extras just get in the way.

The culprit is input lag. That's the term for the delay, in milliseconds, between a TV receiving a signal and the results of that signal appearing on the screen. Those milliseconds are irrelevant for TV shows and movies, and they don't even matter for most games -- the majority of gamers probably wouldn't even notice if their TV was laggy. But if you're an attentive, skilled gamer, especially one who plays "twitch" games like Call of Duty, Halo, or fighting games, especially in online multiplayer environments, input lag can mean the difference between virtual life and death.

CNET just started testing for input lag, and so far we've corralled a handful of 2013 TVs. Here are five of our favorites so far, in ascending order of lag in Game mode -- or the least laggy picture mode, if Game isn't an option. For reference, we grade under 40ms of lag as Good, 40 to 70 as Average, and more than 70 as Poor.

If you've done any research into TVs, Blu-ray players, or Blu-ray in general, you've likely seen the alphanumeric 1080p24 (or 1080p/24).

Understanding what it is, and keeping a lookout for products that can take advantage of it, can result in smoother, more natural-looking movie and TV show playback. I'm not talking about the artificially hypersmooth look of the Soap Opera Effect, but instead the correct cadence of motion at which the film or TV show was shot.

All the judder reducing -- and causing -- awesomeness after the jump.… Read more

Apple's rumored iPhone 5S and low-cost iPhone are said to be coming in a rainbow of colors, according to an article by Macotakara.

While Apple has yet to confirm it's even producing the two new types of smartphone, rumors are flying about the phone's specs and appearance.

The low-cost iPhone, which is said to have a plastic shell rather than aluminum, could come in white, pink, green, blue, and yellow-orange -- or, navy, gold orange, white, and gray, according to MacRumors, which translated the Macotakara article. The phone is also speculated to cost around $350 to $400.… Read more

Engineer Ben Kokes is a lot of things. He's an outdoor enthusiast. He's a Bronco mechanic. He's a tinkerer who builds electronic gadgets for fun. He's also in love.

I'll let him tell his story in his own words: "Once upon a time, a boy met a girl. Then a short amount of time later, the boy decided to design and build a ring for the girl, because doing things in the most complicated way possible is just what he does to show the love." To that end, Kokes made a ring. But not just any ring. It's a titanium ring with internal illumination.… Read more

We all know that white light is created when different color wavelengths combine. So what happens when you use that phenomenon to create a lightbulb?

That's exactly what Dutch designer Dennis Parren did when he developed his CMYK bulb. Well, sort of. Expanded from his original CMYK Lamp 2011 graduation project for Design Academy Eindhoven, the bulb consists of a white LED light source pointing downward. Then placed equidistantly around the bulb, the cyan, magenta and yellow LEDs face up.

This has the rather fun and fascinating effect of casting a triple shadow from whatever comes in front of the LEDs -- one in each of the three colors. … Read more
