Balloon launched from World Scout Jamboree floats across the Atlantic Ocean

You can reach practically any corner of the globe via amateur radio. That’s the message K2BSA wanted to show Scouts at the World Scout Jamboree. Those in the amateur radio association launched four mylar balloons from the Summit Bechtel Reserve in West Virginia, in hopes that one would catch the jet stream and end up on the other side of […]

via HACKADAY: Inside the Mysterious Global Navigation Outage You Probably Didn’t Notice

The entire world has come to depend on satellite navigation systems in the forty or so years since the first Global Positioning System satellites took to orbit. Modern economies have been built on the presumption that people and assets can be located to within a meter or better anywhere on, above, or even slightly under […]

via the ARRL: Earth’s Magnetic North Pole Shifts toward Siberia

National Centers for Environmental Information (NCEI) scientists have updated the world magnetic model (WMM) mid-cycle, as Earth’s northern magnetic pole has begun shifting quickly away from the Canadian Arctic and toward Siberia, an NCEI report said this week. The new WMM more accurately represents the change of the magnetic field since 2015. The alteration could have an […]

via HACKADAY: Jeremy Hong: Weaponizing the Radio Spectrum

Jeremy Hong knows a secret or two about things you shouldn’t do with radio frequency (RF), but he’s not sharing. That seems an odd foundation upon which to build one’s 2018 Hackaday Superconference talk, but it’s for good reason. Jeremy knows how to do things like build GPS and radar jammers, which are federal crimes. […]

via the ARRL: FCC Approves Use of Galileo Global Navigation Satellite System in the US

The FCC has granted, in part, the European Commission’s request for a waiver of Commission rules so that non-federal devices in the US may access specific signals transmitted from the Global Navigation Satellite System (GNSS) known as Galileo. The action means that consumers and industry in the US may access certain satellite signals from the Galileo […]

via HACKADAY: Teddy Ruxpin: Navigate to 143 Main Street

In the United States, TV and radio stations have to give the opportunity of equal airtime to all candidates. In that spirit, we thought we should show you [Jayden17’s] hack that puts Google Assistant into a Teddy Ruxpin. You can see the hacked bear do its thing in the video below. Teddy was the best-selling toy […]

via HACKADAY: Fail of the Week: How Not To Build Your Own DGPS Base Station

GPS is the modern answer to the ancient question about one’s place in the world yet it has its limitations. It depends on the time of flight of radio signals emitted by satellites twenty thousand kilometers above you. Like any system involving large distances and high velocities, this is bound to offer some challenges to […]

via HACKADAY: A Talking Clock For The 21st Century

The Talking Clock service is disappearing, and it’s quite possible that few of you will be aware of its passing. One of the staples of twentieth-century technology, the Talking Clock service was the only universally consumer-available source of accurate time information away from hourly radio time signals in the days before cheap radio-controlled clocks, or […]

via the ARRL: “Quantum Radio” May Offer New Twist on Communicating in Problematic Environments

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated that quantum physics might enable communication and mapping in locations where GPS, cell phones, and radio is not reliable or don’t work at all, such as indoors, in urban canyons, underwater, and underground. NIST announced the technology advance on January 2. The technology may have marine, military, […]

Virginia Tech Expert to Study August Eclipse for Impacts on Radar, Ham Radio, GPS

August 21 is a once-in-a-lifetime opportunity for many in the U.S. to see a total eclipse — but for scientists and engineers, it’s a chance to conduct research on systems we rely on for communication, safety and even transportation. A Virginia Tech expert, backed by research funding from NASA and the National Science foundation, will […]

via HACKADAY: Serious DX: The Deep Space Network

Humanity has been a spacefaring species for barely sixty years now. In that brief time, we’ve fairly mastered the business of putting objects into orbit around the Earth, and done so with such gusto that a cloud of both useful and useless objects now surrounds us. Communicating with satellites in Earth orbit is almost trivial; […]

via HACKADAY: Micro Radio Time Station Keeps Watch in Sync

The US National Institute of Standards and Technology (NIST) broadcasts atomic clock time signals from Fort Collins, Colorado on various frequencies. The WWVB signal on 60 kHz blasts out 70,000 watts that theoretically should reach the entire continental US. Unfortunately for [Anish Athalye], the signals do not reach his Massachusetts dorm, so he built this […]

via HACKADAY: Rubidium Disciplined Real Time Clock

[Cameron Meredith] starts the Hackaday.io page for one of his projects by quoting a Hackaday write-up: “A timepiece is rather a rite of passage in the world of hardware hacking“. We stand by that assertion, but we’d say most of the clocks we feature aren’t as capable as his project. He’s made a real-time-clock module […]
