Yagi-Uda antennas, or simply “Yagis”, are directional antennas that focus radio waves to increase gain, meaning that the radio waves can travel further in that direction for a given transmitter …read more Continue reading Printing Antennas on Circuit Boards
It may be hard to believe, but it’s time for the Hackaday Prize again! The 2023 Hackaday Prize was announced last weekend at Hackaday Berlin, and entries are already pouring …read more Continue reading Hackaday Links: April 2, 2023
It’s been a long time since vacuum tubes were cutting-edge technology, but that doesn’t mean they don’t show up around here once in a while. And when they do, we …read more Continue reading Two-Tube Spy Transmitter Fits in the Palm of Your Hand
After passing an exam and obtaining a license, an amateur radio operator will typically pick up a VHF ratio and start talking to other hams in their local community. From …read more Continue reading Hams Watch For Meteors
The amateur radio community often gets stereotyped as a hobby with a minimum age requirement around 70, gatekeeping airwaves from those with less experience or simply ignoring unfamiliar beginners. While …read more Continue reading Long-Distance Gaming Over Packet Radio
Those who have worked with high voltage know well enough that anything can be a conductor at high enough voltages. Similarly, amateur radio operators will jump at any chance to …read more Continue reading Enormous Metal Sculpture Becomes an Antenna
Astronomers have had to reclassify a bright radio galaxy in the sky after it was found to have redirected a jet of radiation straight towards Earth. The event marks the first observation of a reorientation so dramatic that it changes the category a gal… Continue reading Giant galaxy redefined after flipping jet to point straight at Earth
As any radio amateur will tell you, the world of radio abounds with exciting possibilities. Probably the simplest pursuit of them all is that of the SWL, or short wave …read more Continue reading Review: XHDATA D-219 Short Wave Radio Receiver
Almost all of modern society is built around various infrastructure, whether that’s for electricity, water and sewer, transportation, or even communication. These vast networks aren’t immune from failure though, and …read more Continue reading Building A Communications Grid with LoRaType
If you could zoom way, way out to look at the universe at its largest scale, you’d see that it’s made up of a colossal cosmic web. Now, astronomers have detected shockwaves moving through this web, providing new insights into large-scale magnetic field… Continue reading Astronomers detect shockwaves in colossal cosmic web
