Researchers at the US National Institute of Standards and Technology (NIST) have shown that a cloud of atoms can be used as a receiver to pick up video transmissions. The team demonstrated this “Atomic Television” by transmitting live video feed and ev… Continue reading “Atomic Television” transmits live video through cloud of strange atoms
The term “phased array” has been around for a long time, but in recent years we’ve heard more and more about the beam shaping that’s possible with phased array antennae. …read more Continue reading Reverse Engineering A Phased Array System Reveals Surprising Details
Astronomers have detected an extremely strange radio signal from a distant galaxy that pulses with a heartbeat-like rhythm. This signal lasted about 1,000 times longer than other fast radio bursts (FRBs), and had a clear periodic pattern to its pulses…. Continue reading Bizarre radio burst with “heartbeat” rhythm is longest detected by far
The proliferation of software-defined radio (SDR) technology has been a godsend for RF hobbyists. SDR-based receivers and transmitters have gotten so cheap that you’ve probably got a stick or two …read more Continue reading Bringing Some Discipline to an SDR Transmitter
Before the days of MP3 players and smartphones, and even before portable CD players, those of us of a certain age remember that our cassette players were about the only …read more Continue reading Pocket Radio Powered By Tiny Microcontroller
Astronomers have discovered a super strange neutron star that challenges our understanding of them – but may help unlock the mystery of fast radio bursts (FRBs). The object spins far slower than any other known neutron star, and gives off seven distinc… Continue reading “Impossible” neutron star spins too slowly and emits 7 types of signals
Affordable and reliable cell phones have revolutionized the way we communicate over the last two decades or so, and this change was only accelerated by the adoption of the smartphone. …read more Continue reading Long-Distance Text Communication with LoRa
Astronomers have discovered what may be the brightest pulsar in the sky. Despite its intense light the pulsar has long evaded detection, and was only revealed thanks to a telescope equipped with some cosmic “sunglasses.”Continue ReadingCategory: Space,… Continue reading Telescope “sunglasses” reveal brightest extragalactic pulsar ever found
Most crystal radio receivers have a decidedly “field expedient” look to them. Fashioned as they often are from a few turns of wire around an oatmeal container and a safety …read more Continue reading Multiband Crystal Radio Set Pulls Out All the Stops
These days, many people love having some lo-fi beats on when they chill and study. This has led to a cottage industry dedicated to producing said beats, and the format …read more Continue reading Lofipi Keeps the Chill Beats Coming
