In the world of electronic components, there are many devices out there that do their job well and reliably, but are almost never heard of – even though they may be vital to equipment that plays a role in our technology-driven lives. The radio frequency (RF) circulator is just such a device: it has simply done its job as a nondescript box of gubbins buried in radio communications systems, quietly directing radio frequency signals to the places they should go. Now researchers at the University of Texas have given the RF circulator a makeover. Not only is the new prototype smaller, lighter, and cheaper, it's also claimed to be easily adapted to different frequencies on the fly, which is something the old style circulator cannot do.  Read More

Two issues preventing the widespread uptake of electric vehicles are recharging time and lack of range. Now, scientists have shown one potential means of negating these issues. Their demonstration of electric power transfer via the car-wheel is claimed as the world's first.  Read More

A team of researchers from Stanford University and the University of California, Berkeley, has created prototype radio-on-a-chip communications devices that are powered by ambient radio waves. Comprising receiving and transmitting antennas and a central processor, the completely self-contained ant-sized devices are very cheap to manufacture, don't require batteries to run and could give the "Internet of Things" (IoT) a serious kick start.  Read More

The new method will attempt to find traces of a tell-tale radio signal, known as an Io-con...

A new technique pioneered by a team of scientists from the University of Texas, Arlington, may hold the key to detecting moons orbiting distant exoplanets, a feat which is currently beyond the grasp of modern astronomy. Such a technique would afford scientists a greater opportunity of discovering a planetary body capable of sustaining life.  Read More

Artist's concept of the Juno flyby (Image: NASA)

If you want to have a starship captain’s view of flying past the Earth, then NASA is happy to oblige. This week, the space agency released a video made of images taken by the Juno space probe as it shot past our planet last October. The unmanned spacecraft was using the Earth’s gravity to build up its velocity by over 8,800 mph (14,100 km/h) and slingshot it on its way to Jupiter. And as it did so, it took the time to receive a “Hi” from ham radio operators back home.  Read More

A team of engineers from Columbia University has created a nano-mechanical system with the ability to create FM radio signals. In other words, they've built what is effectively the world’s smallest FM radio transmitter.  Read More

ScanEagles can provide real time telemetry for prolonged periods (Image: Boeing)

Radio has come a long way since Marconi bashed a telegraph key and radar is a miracle compared to when it was just a squiggle on a cathode tube, but despite a century of advances, they’re still prone to the same problems as the first pioneers encountered. For five days in July, the Office of Naval Research’s (ONR) Research Vessel (R/V) Knorr made a survey in the waters off Virginia Beach, Virginia using ScanEagle UAVs to study the effect of oceanic and atmospheric changes on radar and radio waves with the aim of producing more secure military communications and improve the ability of radar to detect hostile craft.  Read More

HAARP operational site on the edge of Denali State Park northeast of Anchorage, Alaska (Ph...

Reports that the High Frequency Active Auroral Research Program (HAARP) had been shut down permanently were apparently a bit premature. According to HAARP program manager James Keeney, the facility is only temporarily off the air while operating contractors are changed. So why does anyone care? Despite being associated with various natural disasters over the past two decades by the conspiracy fringe, HAARP is in reality a facility for studying the ionosphere. Let's take a look at the goings on at HAARP – past, present, and future.  Read More

Radio plays can transport listeners to far away exotic settings but the BBC’s prototype Perceptive Radio aims to give listeners a more localized experience. Shown to the public recently at the Thinking Digital Conference in Gateshead, UK, the Perceptive Radio uses local data and onboard sensors to adjust itself and even alter the script of a radio play in real time to reflect local conditions. The goal is to make listening to the radio more like attending live theater.  Read More

The Rukus XL unveiled at CES 2013 joins Eton's Rukus line

At CES Unveiled, we had the chance to sit down with Etón, a company that builds products for entertainment and safety that can rely on hand cranks or solar power to keep them running. In addition to the FRX series and the Rukus and Rukus Solar it was also spruiking at last year's show, the company is displaying its new ZoneGuard series alongside a couple of additions to its Rukus line and the new BoostSolar Mobile Charging Solution.  Read More
