Astronomers have taken a close-up image of a radio jet emitted by a supermassive black hole for the first time. The Event Horizon Telescope (EHT) has zoomed in on this jet with 16 times the resolution and at 10 times higher frequencies than previous ob… Continue reading Event Horizon Telescope snaps close-up of supermassive black hole jets
Dipoles are a classic builder’s antenna, after all they are usually little more than two pieces of wire and a feedline. But as [Rob] shows us in the video below, …read more Continue reading A Cheap Dipole Antenna from an Extension Cord
We don’t normally embrace the supernatural here at Hackaday, but when the topic turns to the radio frequency world, Arthur C. Clarke’s maxim about sufficiently advanced technology being akin to …read more Continue reading New Video Series: Learning Antenna Basics with Karen Rucker
Last year, as my Corona Hobby™, I took up RC plane flying. I started out with discus-launched gliders, and honestly that’s still my main love, but there’s only so much …read more Continue reading You Can’t Fix What You Can’t Measure
What do you do with floral wire and balloons from Dollar Tree? If you are [Ham Radio Crash Course], you make a ham radio antenna. Floral wire is conductive, and …read more Continue reading Balloon Antenna Doesn’t Need a Tower
Japanese astronomers have discovered the echoes of a “dying” supermassive black hole. While the object is quiet now, the team spotted the signatures of two huge radio jets that indicate it only recently fell silent after a bright, active phase.Continue… Continue reading Astronomers discover dying echoes of a supermassive black hole
It’s easy to get caught up in a build and forget that the final version usually needs some sort of enclosure, especially things with sensitive electronics in them. The [Director …read more Continue reading Radio Build Goes Outside The Box
Astronomers are another step closer to solving one of the most intriguing cosmic mysteries of recent times – fast radio bursts (FRBs). A team has now traced five signals to their points of origin within the spiral arms of galaxies, narrowing down the l… Continue reading Five fast radio bursts tracked to home galaxies
Swim coaches have a difficult job, as they have to shout in order for swimmers to hear them – and even then, they still may not be heard. The Sonr system is designed to address that problem, using one-way radio communications.Continue ReadingCategory: … Continue reading Sonr tech lets coaches talk to swimmers by radio
There’s no doubt that the RTL-SDR project has made radio hacking more accessible than ever, but there’s only so far you can go with a repurposed TV tuner. Obviously the …read more Continue reading The Evil Crow is Ready To Cause Some RF Mayhem
