“Scientists from ITMO’s ChemBio Cluster developed a method for printing holograms in color in a project supported by the Russian Science Foundation. At the core of the method are volume Bragg gratings, special films with reflecting properties. The proposed …
“When cell phones, electric vehicle chargers, or other electronic devices get too hot, performance degrades, and eventually overheating can cause them to shut down or fail. In order to prevent that from happening researchers are working to solve the problem …
“A Working Replica of the classic 555 timer made using discrete components A fully functional replica of the classic 555 timer made using discrete through hole components which include only basic jellybean components like (to - 92) BJTs , 1/4Watt resistors …
“Machine learning used to be the preserve of university research departments with money to burn on high-power, high-cost kit – but not any more! Thanks to a new breed of affordable dev boards, anyone can get in on the act at …
“Launching in August 2022 and arriving at the asteroid belt in 2026, NASA’s Psyche spacecraft will orbit a world we can barely pinpoint from Earth and have never visited. The target of NASA’s Psyche mission – a metal-rich asteroid …
“This project will show you how to create a RC Controller. After making hovercrafts, I decided that I would need a remote control if I wanted to use a home made drone (maybe for a future project). As a consequence …
“Scientists in Switzerland and Germany have achieved efficient electron-beam modulation using integrated photonics – circuits that guide light on a chip. The experiments could lead to entirely new quantum measurement schemes in electron microscopy. The transmission electron microscope (TEM) can image …
“Computer systems that are physically isolated from the outside world (air-gapped) can still be attacked. This is demonstrated by IT security experts of the Karlsruhe Institute of Technology (KIT) in the LaserShark project. They show that data can be transmitted …
“After more than two decades of development, NASA’s next-generation space telescope is on the launch pad. The James Webb Space Telescope is due to launch on Saturday (Dec. 25) during a 32-minute window that opens at 7:20 a …
“A Chinese physicist has said that a new wind tunnel in Beijing to be unveiled “soon” will put China decades ahead of the rest of the world in hypersonic technology. Chinese Academy of Sciences researcher Han Guilai told an online …
