The WristBow Mk II stores multiple carbon fiber darts in its ammo clip, which drop into pl...

When we last heard from German cyberpunk weapons hobbyist Patrick Priebe, he'd made a set of X-Men-inspired goggles that incorporated burning lasers. Some time before that, however, he showed us a wrist-mounted, laser-sighted crossbow that he'd created. Now, he's just completed a new-and-improved "semi-automatic" take on that crossbow.  Read More

Researchers have developed a wireless system that directly powers Wi-Fi connections using ...

One of the advantages of the "connected world" is that myriad different devices can interact with each other over Wi-Fi to exchange data, control equipment, and generally lay the foundations of the Internet of Things of the not-too-distant future. Unfortunately, on the downside, all of the Wi-Fi connections need power to operate, and this severely restricts the pervasiveness of this technology. However, researchers at the University of Washington have developed a system that they say eliminates the need for power supplies for these connections by using what is known as radio frequency (RF) backscatter technology.  Read More

Nanospheres were specifically created to protect the lithium from reacting chemically with...

Stanford University researchers claim to have created the first stable pure lithium anode in a working battery by using carbon nanospheres as a protective sheath to guard against degradation. As a result, the researchers predict that commercial developments may eventually result in anything up to a quadrupling of battery life in the not-too-distant future.  Read More

Amazon has announced a new 3D Printed Products store. The store has launched with more than 200 print-on-demand designs. Users can customize items like earrings, pendants, rings and bobble head dolls using a special widget, before having the item 3D-printed and delivered.  Read More

Google and the IEEE are offering a US$1 million prize in their Little Box challenge

The old saying says good things come in small packages. Google and the Institute of Electrical and Electronic Engineers (IEEE) seem to agree having launched the Little Box Challenge, an open competition with a US$1 million first prize to find innovative electronic designs to shrink power inverters down from their current bigger-than-a-bread-box size to something less than the size of a small laptop.  Read More

Philips connected lighting system for offices using LED luminaires with additional embedde...

With corporate showmanship and architectural one-upmanship being what they are, newly-built company headquarters are often lavish affairs. The Edge in Amsterdam is no different. Not only is it good looking sustainably-designed, but its lighting does more than just brighten up a room.  Read More

Efficient as fiber optic cables are at transmitting data in the form of light pulses, they do need to be physically supported, and they can only handle a finite amount of power. Still, what's the alternative ... just send those focused pulses through the air? Actually, that's just what scientists at the University of Maryland have already demonstrated in their lab.  Read More

Buenos Aires is replacing 70 percent of its city lighting with Philips connected LED light...

LED lighting offers a host of benefits for cities, such as reduced energy usage and costs. For Buenos Aires, which is in the process of having its lighting infrastructure upgraded, one of the benefits is the increased level of control it provides. Gizmag took a look at technology being used.  Read More

The Solderdoodle is designed to be charged from a USB port

The days of being tied to a mains outlet to do a bit of soldering are long gone, but what about the techie on the go who doesn't want to be lumbered with chargers, batteries, and cans of gas? Solderdoodle is a partly 3D printed device that can be charged using a standard USB cable.  Read More

A new high-temperature superconductor can trap a record magnetic field of 17.6 Tesla, in a...

Researchers at the University of Cambridge have created a new high-temperature superconductor capable of trapping a magnetic field of 17.6 Tesla, improving on a record set over a decade ago. The advance is yet another step toward making superconductors viable for building effective large-scale smart electricity grids, maglev trains and flywheel energy storage.  Read More
