Samsung Galaxy Tablet may run on Intel chip

Samsung may do something it has never done: Put an Intel chip in a Galaxy Tab.

The Samsung Galaxy 10.1 Android tablet is expected to sport a dual-core 1.6GHz Intel Atom CloverTrail+ chip, industry sources familiar with the product told CNET. The plus sign means the CloverTrial chip packs a high-performance PowerVR SGX544 MP2 graphic processing unit from Imagination Technologies.

Other specs include Android 4.2.2 and a 1,280 x 800 display.

Samsung is slated to reveal the Galaxy Tab at Computex, which starts June 4 in Taipei.

Get a retractable universal laptop charger for $20

I hate cord clutter. But when I travel (like I'm doing right now), I'm stuck with it, what with all the power cords I have to stuff into my carry-on.

My laptop's AC adapter is among the worst offenders (two cords!), which is why I'm thinking very seriously about this: ZipKord has the Retractable Universal Laptop Combo-Charger for $20, plus a very reasonable $3.75 for shipping. Regular price: $79.99.

This travel-friendly kit consists of two retractable cords -- one for AC outlets, one for in-dash cigarette lighters -- and a set of 11 tips. … Read more

Three great-sounding affordable sound bars

No one can deny the popularity of sound bar speakers, but I've always been frustrated by their sound quality. There were exceptions; the $899 Atlantic Technology PB-235 and $699 SpeakerCraft CS3 are quite good, but in the more popular $300-to-$400 range the 'bars weren't all that great. Granted, they were a big step up from TV speakers, but their sound was still a compromise, compared with what's available from the better $300-to-$400 Emotiva and Audioengine self-powered stereo speakers (they get hooked up from your TV's stereo analog jacks).

A few weeks ago I spent … Read more

Lawsuit claims Apple sold iPhone 4 with bad on-off button

A lawsuit has been brought against Apple for allegedly selling iPhone 4 smartphones with faulty power buttons. The suit, which seeks class-action status, claims that Apple knew about the issue and failed to fix the problem.

Debra Hilton filed the lawsuit in San Jose, Calif., alleging that she and "thousands of iPhone 4 users" were sold the device with on-off buttons that stopped working shortly after the 1-year warranty was up. The problem purportedly had to do with a defective flex cable that controlled the power button.

"The Apple iPhone 4 is plagued by a latent defect … Read more

Home networking Part 7: Power line connections explained

Editors' note: This post is part of an ongoing series. For the other parts, check out the related stories section below.

Power line networking basically turns a building's existing electrical wiring -- the wires that carry electricity to different outlets in the house -- into network cables, meaning they also carry data signals for a computer network. And this means virtually all households, in the U.S at least, are "wired for" power line networking. It doesn't replace a regular network, so you'll still need a router, but it's a good way to extend … Read more

Review: Create magic-sketch photos with Wondershare PowerSketch

The most impressive thing about PowerSketch is that it works on the fly. There are many photo editing or augmentation apps that allow you to change the features in a photo or make it look different than it should after the fact, but PowerSketch shows the final image as you view it, within the camera screen. Even more impressive, it can do the same thing for videos, making this one of the better photo manipulation apps on the App Store.

PowerSketch is a well-designed app from start to finish. Designed to look like a notebook and featuring a number of … Read more

Working robot mecha suit is built for kids

What do you get the kid who has it all? A robot mecha suit wouldn't hurt.

Levitating bike powers your phone, creates Wi-Fi hot spot

When you pedal a bicycle, the kinetic energy is channeled into propulsion, but what if it could be used in other ways? Architect Michael Strain isn't the first to think of using pedal power to charge your gadgets -- in fact, there are products on the market that already allow you to harness that excess energy -- but his concept bike, has a few other tricks up its suspension.

The bike, called Levitation and designed for the 2013 Hi-Macs Annual Design Contest, looks like a more low-tech Tron Cycle. It features an on-board generator and battery that stores the power collected while cycling. The power can then be used in two ways: charging small gadgets via the USB port on the bike's handlebars, or sending it into your home's power supply via a drain cable to alleviate grid usage. … Read more
