“Morse Code, often referred to by Ham Radio folks simply as CW, is usually sent using a hand operated switch called a ‘Key’. You’ve seen these somewhere, the old telegraph key. Another device called a ‘Keyer’ can automatically generate …
“QUANTUM PHYSICS In a new breakthrough, researchers at the University of Copenhagen, in collaboration with Ruhr University Bochum, have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather …
“With being active in home automation for the last 5 years, Ive by now (like most of you) automated all my lights and put temperature and humidity sensors on more places than strictly necessary. So, it only logical next step …
“As early as 2030, batteries in electric vehicles could fully meet the need for short-term electricity storage around the world. By connecting them to the power grid they can provide their stored energy, improving energy security and enabling renewable technologies …
“By using ultrafast laser flashes, scientists at the University of Rostock in collaboration with researchers of the Max Planck Institute for Solid State Research in Stuttgart have generated and measured the shortest electron pulse to date. The electron pulse was …
“Salt-rejecting microchannels help make seawater drinkable using the power of the sun. A solar distillation device can purify brine from reverse osmosis plants with over 10 percent salinity, as well as water taken directly from the Red Sea. The technology …
“Published in Science, a collaboration between teams from the National Graphene Institute (NGI) at The University of Manchester, and the École Normale Supérieure (ENS), Paris, demonstrated the Hebbian learning in artificial nanochannels, where the channels showed short and long term …
“Made a Custom HexLight consist of WS2812 2020 package LEDs and Attiny85 all jam packed in a 3D Printed body. HEXLIGHT is a small, hexagon-shaped RGB light that is created using custom PCBs and a 3D-printed body. An Attiny85 MCU …
“UCLA study overcomes the effects of Earth’s gravity, replicating conditions on other planets, stars. Solar flares and other types of space weather can wreak havoc with spaceflight and with telecommunications and other types of satellites orbiting the Earth. But …
“The cosmos seems to have a preference for things that are round. Planets and stars tend to be spheres because gravity pulls clouds of gas and dust toward the center of mass. The same holds for black holes — or, to …
