Review: Photojojo's Pocket Spotlight

By - April 4, 2013 11 Pictures
Never before have I so wished that I could use a device for taking photos of that device. That was certainly the case with Photojojo’s US$30 Pocket Spotlight, however. It’s simply a tiny battery-powered array of 32 LED bulbs, that provide a source of soft, even light as an alternative to the harsh light of a flash. While serious photographers will already have proper lighting systems of their own, it’s a nice tool for all the point-and-shooters out there. Read More

“Big Air Package” is claimed to be the largest indoor scultpure ever made

By - March 21, 2013 23 Pictures
Bulgarian-born artist Christo has unveiled his latest work, dubbed “Big Air Package,” which is billed as the largest indoor sculpture created to date. Whether the claim is true or not, the installation is most certainly a significant feat of engineering in its own right. Big Air Package is installed in Germany’s Gasometer Oberhausen, and almost fills the cavernous space of an empty gas tank, the inflated envelope being 90 meters (295 feet) high, and 50 meters (164 feet) in diameter.

StemLite combines a handlebar stem and bike light in one device

By - February 28, 2013 7 Pictures
Imagine if new cars didn’t come with their own headlights, and buyers were expected to supply their own. It would be kind of silly, right? Well, that’s what the situation is with most commuting bicycles. While a few bikes have built-in lights, consumers are generally expected to purchase one separately, then attach it to the bike. Of course many people simply don’t bother, while others buy a light but then get caught in the dark without it. That’s why California-based cyclists Nick Sweeney and James Voshell have created the StemLite. Read More

New transparent, flat, flexible image sensor has potential for gesture control displays

By - February 21, 2013 2 Pictures
A research team from the Johannes Kepler University Linz in Austria has developed an image capturing device using a single sheet of polymer that is flat, flexible and transparent. The researchers say the new image sensor could eventually find its way into devices like digital cameras and medical scanners, and that it may help to usher in a new generation of gesture-controlled smartphones, tablets and TVs.

New capacitor developed for brighter camera flashes on mobile devices

By - February 20, 2013 2 Pictures
While stand-alone compact cameras are increasingly at risk of being made obsolete by smartphone cameras, they do still have their advantages. One of those advantages is the fact that, in most cases, their flashes are considerably more powerful. Smartphones may soon be catching up in that area, however, thanks to a new small-but-mighty capacitor paired with a dedicated xenon flash. Read More

Breakthrough laser cooling system could save space and energy

By - February 13, 2013
A research team at Singapore’s Nanyang Technological University (NTU) has successfully used a laser to cool down a semiconductor material known as Cadmium Sulfide. The results of the recently published study could lead to the development of self-cooling computer chips and smaller, more energy efficient air conditioners and refrigerators that don't produce greenhouse gases.

Unlocking color mechanism of peacock’s feathers could lead to next-gen color displays

By - February 7, 2013 3 Pictures
Structural color, which is the foundation that makes things like a peacock's tail feathers appear iridescent, has been an area of study for scientists as they try to adapt it for use in everyday technologies – only without the “rainbow effect” that makes the colors unstable depending on the angle of view. Now, Researchers at the University of Michigan have mimicked the peacock's color mechanism in an approach that could lead to high resolution reflective color displays and have implications for data storage, cryptography and counterfeiting.
