MIT produces new metamaterial that acts as a lens for radio waves

We expect the world to be predictable. Water flows downhill, fire burns and lenses bend light in a particular way. That worldview took a jolt as Isaac Ehrenberg, an MIT graduate student in mechanical engineering, developed a three-dimensional, lightweight metamaterial lens that focuses radio waves with extreme precision. That may not seem too disturbing, but the lens is concave and works in exactly the opposite manner of how such a lens should.Read More

Spotify radio now free on Android & iOS in U.S.

The Spotify app for mobile devices is free, but to get any usability from it beyond the trial period it requires the paying of a monthly subscription fee. While those using the desktop app can make do with adverts and playback limitations, there is no other option for mobile users besides paying the aforementioned fee. However, one feature of the Spotify app has been made available to U.S. users completely free, with the radio function now available to both iOS and Android users.Read More

Computer model designed to lessen electromagnetic interference in EVs

While electric cars are often touted as being less mechanically complex than their internal combustion-engined counterparts, there is at least one way in which they’re considerably more “involved” – their radios. Because electrical signals emitted by the car can potentially interfere with incoming radio signals, manufacturers must do things such as insulating the motor and shielding the cables. This adds time and material expenses to the production process. Now, however, researchers from Germany’s Fraunhofer Institute for Reliability and Microintegration have developed technology to help minimize the problem.Read More

Eton (hand) cranks out new self-powered products at CES

While insufficient battery-life can be annoying in most mobile devices, getting cut off from the outside world because your radio has run out of juice can be much more serious. This is why Eton has been producing various devices powered by hand-turbines and solar panels for some time now. Today’s CES Unveiled saw Eton demonstrating its latest FRX line of self-powered radios that come in three flavors – the FRX 3 and FRX 2, which both sport a solar panel and hand turbine, and the FRX 1, which features just the hand-turbine. Also on show was Eton’s new Rukus portable Bluetooth sound system, which comes in battery- and solar-powered versions.Read More

Card Radio: recyclable, aptly named

Card Radio was conceived as an environmentally friendly piece of consumer electronics, presumably with the mass market in mind. Its entire housing is made from recyclable, though not recycled, cardboard. Despite its low cost and eco-credentials, Card Radio aims not to sacrifice elegance, harkening back to the 1960s aesthetic that designer Chris McNicholl claims as its influence.Read More

Full-duplex technology could double wireless capacity with no new towers

Earlier this year, Stanford University researchers created a full-duplex radio that allowed wireless signals to be sent and received simultaneously, thereby doubling the speed of existing networks. Using the same approach, researchers at Rice University have now developed similar full-duplex technology that would effectively double the throughput on mobile networks without the addition of any extra towers.Read More

Improved tracking system being developed for firefighters

Even though firefighting is one of the most dangerous jobs in the world, firefighters still communicate using analog radio signals, that can be blocked by concrete walls. This means that, upon venturing into a burning building, a firefighter might have no way of letting their commander know their present location – a situation that could prove deadly, if they ended up trapped or injured. In order to address the situation, the U.S. Department of Homeland Security’s Science and Technology Directorate has created a new three-part system that lets fire crews keep track of the location and well-being of every member of their team, all the time.Read More

Sony launches its first DAB+ radios

When I tuned into my first DAB broadcast a few years ago and was treated to crackle-and-hiss-free CD quality digital audio, I must admit to being impressed. Now an enhanced version of the standard is being rolled out across Europe which uses a more efficient audio codec and offers listeners even more access to digital services, and Sony has launched two new products to greet it. Heading for UK bedrooms will be the XDR-C706DBP DAB+ radio alarm clock, while living rooms can enjoy the natural wood finish and retro-styling of the XDR-S16DBP.Read More

H2O Power radio runs on water from the shower

For all the people out there who like listening to the radio while they’re in the shower, various companies offer waterproof battery-operated “shower radios.” There’s nothing particularly wrong with these radios, but ... why change or recharge the batteries if you don’t have to? No, we’re not suggesting running a power cord into the shower. Instead, you might be interested in getting an H2O Power water-powered radio.Read More

Breville combines two breakfast favorites in one device

Breakfast is said to be the most important meal of the day, and for me a few rounds of toast and a spot of rousing music on the radio is the perfect way to start off the day. UK kitchen appliance manufacturer Breville has taken those two kitchen favorites and merged them into one device – the Radio Toaster. Its smooth lines, matt black/silver finish and silver circular speaker give it a 1950s retro feel, but the AM/FM radio's display is digital rather than analog, and it also includes some modern toasting innovations to help users get the best bread-browning results.Read More
