Ant-sized radios could help connect trillions of devices to the Internet of Things

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.

Juno sends back "starship" view of Earth while ham radios say "Hi"

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

Office of Naval Research uses UAVs to study radio propagation

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 ionospheric research program set to continue

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

Prototype BBC radio rewrites scripts on the fly to reflect local conditions

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

Eton expands off-the-grid device range

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

Plugg radio switches on and off with a cork

Radio receivers have changed greatly since the first units became widespread in homes at the beginning of the previous century. However, throughout each iteration, switching a radio on has usually entailed pressing a physical button. Plugg takes a different approach, employing a cork plug as a method of switching on or off.
