The jaja is a computer stylus that transmits user pressure using high-frequency sound

Drawing styluses are, for the most part, simply glorified sticks. They do what your finger would do, but have a finer point. The new jaja stylus developed by Australia’s Jon Atherton, however, has a few tricks up its sleeve – the big one is, it is capable of registering 1,024 levels of user-applied pressure, which it transmits to the tablet or smartphone’s microphone using sound. The resulting lines drawn on the screen will be of varying thicknesses, depending on the amount of pressure applied.  Read More

The Smart E-book System incorporates features that are intended to make the reading of dig...

There may indeed come a day when printed books and magazines have been gone for so long, that nobody cares how little reading a digital document resembles reading one printed on paper. That day is not yet here, however – most of us still like our e-reading experience to be as close as possible to that of reading a book. To that end, this week a team from the Korea Advanced Institute of Science and Technology (KAIST) announced the development of new e-reading system, that brings several book-like capabilities to tablets and smartphones.  Read More

3D Systems' Cubify 3D printer is ready to work right out of the box

Since becoming more widely available to the public, people have found a myriad of uses for 3D printers, whether it's recreating bone, constructing replacement shells for hermit crabs, or simply customizing mini robot figurines. Unfortunately, most 3D printers still have one drawback over other types of printers, in that they typically need to be put together like a hobby kit. Seeing as most electronics are purchased fully intact, the idea of having to build a device piece by piece can be off-putting to consumers. 3D Systems is hoping to rectify the problem with its own 3D printer that actually works right out of the box, along with a new Cubify platform for designing and distributing printed creations.  Read More

Panasonic's 4K2K display packs around 8.29 million pixels into a 20-inch display

At CES this week, Panasonic unveiled what it claims is the world's smallest, thinnest 4K2K-resolution, 20-inch IPS Alpha LCD panel. The prototype ultra-high definition monitor is only 3.5 millimeters thick, yet has about four times the resolution of a standard HDTV, at 3,840 x 2,160 pixels - this translates to approximately 8.29 million pixels in total, with the "world's highest pixel density of 216 pixels per inch."  Read More

Sony's new Crystal LED Display prototype produces an image using a layer millions of LEDs

While OLED may have staked a claim as the next generation display technology to beat, Sony has chosen CES 2012 to unveil a new display technology called “Crystal LED.” Instead of an LED or CCFL backlight shining through an LCD layer to produce an image, the Crystal LED display technology is a true LED TV that uses a layer of tiny self-emitting LEDs to directly produce the image – think of it like a high resolution shrunk down JumboTron like those found at sporting stadiums.  Read More

In addition to the camera, the Drone also now has a new AR.FreeFlight 2.0 application which offers a new flight interface and flight options.  Read More

The Power2U AC/USB Wall Outlet lets you charge devices via a USB Cable, directly from the ...

While it’s certainly convenient that most mobile devices can be charged via one of your computer’s USB ports, what happens if all of the ports are in use? Even if they’re not, you don’t always want your devices and their cables cluttering up your desk. You can buy USB adapters for wall outlets, but then you end up needing to find an available outlet, and subsequently occupying it (in older homes especially, unused AC outlets are often something of a rarity). Now, there’s an alternative to using your computer or an adapter to charge your gizmos – it’s the Newer Technology Power2U AC/USB Wall Outlet.  Read More

Logitech is soon to launch its Cube mouse and presentation device, with automatic 'Present...

When is a cube not a cube? When it's a Logitech Cube. That is, a mouse and presentation device which, though called a Cube is not a cube. You follow? Here's the thing: when you put it on a desk it behaves like a mouse, but when you pick it up it automatically goes into "Presenter Mode" for navigating PowerPoint presentations like a pro (because without one, PowerPoint is really, really hard). But it's the Cube's in-built gestures (all both of them) that separate it from the herd. Warning: this article contains unavoidable double entendres.  Read More

LG will be unveiling the “world's largest 3D Ultra Definition TV” at the Consumer Electronics Show (CES) in January.

The television also utilizes LG's “Slim and Narrow Bezel Design,” which the company feels gives viewers “the most convincing 3D viewing experience currently available outside a movie theater.”  Read More

The various laser-cut wooden panels of Matt Keeler's Fab Boombox snap together to form the...

Music lovers wanting to listen to digital music files on the move are pretty much spoiled for choice these days, whether keeping things personal with players like the Cowon C2 I reviewed earlier in the month, or sharing with friends using something like the FoxL v2 wireless loudspeaker. If commercial designs don't really appeal, though, there is another route - you could always build your own. Matt Keeter's Fab Boombox is just such a device, designed and built for a final class project and featuring laser-cut, snap-together panels housing stereo speakers (said to be loud in a quiet room and quiet in a noisy room), a custom main control board with an MP3 decoder and a 9V battery power source. Digital music is fed into the player via an SD card slot, with the user controlling playback on a touch-sensitive interface.  Read More
