January 2013′s Hottest Gadgets



Razer Ouroboros





The Ouroboros wireless mouse is the fastest responder on the market. A laser and optical sensor detect the tracking surface 10 times quicker than competitors. The resulting one-millisecond response rate puts gamers at a distinct advantage.



Goal Zero Sherpa 50





At less than three pounds, the Sherpa 50 is the lightest solar panel and recharger available. Six hours of sunlight fully charges the 13-volt lithium-ion battery, which can power a USB-connected cellphone for up to 50 hours.



GoPro Hero3





Under three ounces, the Hero3 is the highest-performing video camera of its size. It shoots in 4K—a resolution normally used in cinematic cameras. Action-seekers can snap the Hero3 to helmets with a special mount or film from afar using a remote.



Lexar 256GB SDXC Memory Card





Photographers usually carry extra memory cards, but with the SDXC, there’s no need: At a quarter terabyte, it’s the highest-capacity card in the world. To create more space, engineers placed the storage cells on top of one another, rather than alongside.



Matias Quiet Pro Keyboard





Typing on a Quiet Pro Keyboard produces just 45 decibels of sound—the noise level in a library—making it the quietest mechanical keyboard ever built. To reduce clacking, engineers installed 1.5-millimeter rubber dampers underneath each key.



Brother MFC-J4510DW





At 11 inches deep, the MFC-J4510DW has the smallest footprint of any multifunction inkjet printer. Designers reoriented the paper tray from the traditional portrait to landscape, so it sits entirely inside the printer. And the jets cover more of the page at once, making printing faster.



Fellowes 73Ci





The 73Ci shredder is virtually jam-proof. Paper fed into the mouth encounters a sensor, which measures thickness and signals the motor to run at the appropriate torque—too much paper and it shuts off. Fifty-six pairs of rotating blades cut each sheet into 399 pieces.



Wilson Steam 99S





With enough spin, a tennis ball that looks like it’s soaring out of bounds will drop right inside the court. A player using the Wilson Steam racket will add more than 200 revolutions per minute to his shot. Engineers decreased the traditional number of horizontal strings by four; with fewer strings to flex, the remaining ones snap back faster on impact.



45NRTH Wölvhammer





Bicyclists don’t always break for cold weather. Wölvhammer biking boots will keep their toes toasty. The fleece-lined inner boot has a two-millimeter layer of Aerogel to insulate against a pedal’s cold metal clip. The outer shoe, made from waterproof Cordura, has a polyurethane-coated mudguard.



Pogoseat





With the Pogoseat app, fans in an arena can upgrade their view of the action mid-game. After picking an empty spot from an overhead-seating chart, users pay the difference in ticket price from within the app and move on down.



LiveScribe Sky Smartpen





Notes taken with a LiveScribe Skypen automatically sync to Evernote. As a writer scribbles, a sensor on the pen’s tip tracks movement. A Wi-Fi radio then uploads files to the cloud, so users can access their notebooks anywhere.



Worx SD SemiAutomatic Driver





With the Worx SD SemiAutomatic Driver, DIYers will never fumble to change screwdrivers again. A rotating cartridge holds up to six tips; users cock back the top of the driver to spin the cartridge and release a spring, which pushes the next one into place.


NVIDIA GeForce GTX 690 Review: Rare,Fast,Expensive




We knew this would happen. Every year Nvidia and AMD queue up to release their latest high-end GPUs and, just as tick follows tock, they're swiftly followed up by a card that makes all but the richest of gamers weep: the dual-GPU monster.

This time around it's Nvidia's turn and, as the firm's naming convention dictates, it's the GeForce GTX 690. Let's get this out of the way immediately: the GTX 690 costs £880.

There's no sign of the economies of scale potentially caused by using one heatsink, enclosure or PCB to contain two Kepler cores, and Nvidia has been upfront about the cost of one GTX 690 mirroring that of two GTX 680s.

It's not quite as simple as slapping two of those GTX 680 cores on one PCB, though. As usual with dual-GPU cards, the top-end specification has been trimmed back slightly for the dual-core version.



The GK104 core, for instance, was launched at a headline grabbing 1,006MHz - just 6MHz more than the 1,000MHz which AMD unveiled with its first current-generation card, the Radeon HD 7870. Here, it's dialled down to a still-superb 915MHz. Nvidia's GPU Boost technology is still here, so the card will reach the heady heights of a guaranteed 1,019MHz if any game demands that level of power - a step down from the 1,058MHz of a single GTX 680, but a still a deeply impressive figure.

There's no option of having four gigabytes of RAM attached to each core, either, as is possible with the most expensive GTX 680 cards. The GTX 690 still includes 4GB of GDDR5 RAM across the whole board, and it's still clocked at 6,008MHz.



The fundamental Kepler architecture is still in place. There's no deactivation of streaming multiprocessors or CUDA cores: the GTX 690 boasts a mighty 3,072 stream processors across the card. They’re divided into eight of Nvidia’s Graphics Processing Clusters, each of which contains two of its Streaming Multiprocessors. There’s the small matter of seven billion transistors included – the most we’ve ever seen on a graphics card.

Its price of around £880 is a little more than twice the price of the GTX 680, and that puts the GTX 690 on another level compared to every current generation product - at least, we assume, until AMD releases a dual-core Radeon HD 7000-series card.

Specifications

    Graphics processor Nvidia GeForce GTX 690 4GB, 915MHz
    Pipeline 2 x 1,566 stream processors, 32 ROPs
    Memory 4GB GDDR5, 6GHz effective
    Bandwidth 2 x 192GB/sec, 256-bit interface
    Compatibility DirectX 11, OpenGL 4.1
    Outputs/Inputs 3 x DVI, mini DisplayPort
    Power connections Two 8-pin

10 Best DSLR Cameras for Beginners



A DSLR, or Digital Single Lens Reflex, camera can help one achieve so much more when it comes to picture-taking but the features of a DSLR can get pretty confusing for those who aren’t very familiar with it. So here are ten very easy-to-use DSLRs for newbies in the scene of professional photography or those who simply want more than what a point-and-shoot compact camera can provide.

10. Canon EOS 600D

One of the best for beginners, the EOS 600D is loaded with features that will really come in handy when it comes to developing your photography skills. Featuring an 18-megapixel, 3-inch LCD screen, in-camera guides, and basic as well as creative filters, it’s no wonder why it’s capable of producing excellent photos.



Price: Ranging between $476 to $1,050


9. Nikon D3200

Inexperienced DSLR users, here’s one camera designed specially for you. The D3200 comes with a guide mode option which will be useful for those who aren’t so confident of capturing great shots on their own. Also Wi-Fi compatible, you’ll be able to send images directly to a tablet or smartphone without the hassle of wires.



Price: $650


8. Canon EOS 1100D

Another one with handy in-camera guides, the EOS 1100D proves to be an asset with those new to DSLRs. With it’s DIGIC 4 image processing technology, the camera also makes for a great investment for great photos.



Price: $470


7. Nikon D3100

Most of us are well aware that a DSLR comes with more buttons than a compact due to its many features but sometimes, especially in the case of newbies, we’re not quite sure what button does what. The D3100, with its chunky and self-explanatory buttons, will help ensure that such a scenario will not happen and just like the D3200, it also incorporates a guide mode option.



Price: $520


6. Pentax K-30

This DSLR is perfect for the outdoorsy person. The K-30 has been designed with a body that will weather almost any harsh outdoor elements. In addition to that, it has a very useful shake-reduction system for any bumps you might encounter along the way.



Price: $979.99


5. Nikon D5200

If you’re not exactly new to DSLRs but not yet confident enough to handle something too professional, the D5200 is the one for you. With plenty of powerful features, such as the 24.1-megapixels, 3-inch vari-angle monitor and 39-point AF system, this sturdy toy will have you engrossed for hours.



Price: $1190


4. Nikon D90

For those looking to familiarize yourselves with the manual controls of a DSLR then you might want to consider the D90. It comes with extensive manual features and functionality but once you’ve grasp it all, you’ll find that this highly durable DSLR is capable of taking stunning images as well as videos.



Price: $765


3. Pentax K-r

Older than the K-30, the fact that the K-r is still around speaks volumes of its performance. With an impressive 11-point auto-focus system and great yet easy-to-use features, the K-r is as dependable as it is resilient.



Price: $675


2. Sony A37

The A37 is more an SLT (Single Lens Translucent technology) than an SLR and is great for those who are more interested in cameras with electronic viewfinders, as opposed to optical ones. It definitely has a unique design but more importantly, it’s also beginner-friendly.



Price: $655


1. Canon EOS 650D

Even though it’s labelled as an ‘entry-level’ model, this last one on the list has specifications and a feature-set that’s not exactly basic, which is why the EOS 650D is better suited for beginners who are up for a little challenge. But even if you’re not, don’t cross it off your list just yet! The EOS 650D is surprisingly easy to master, plus it comes with a nifty LCD touchscreen.



Price: $750
