Cracking a Mystery of Massive Black Holes and Quasars with Supercomputer Simulations

“A discovery that provides new insight into how galaxies evolve At the center of galaxies, like our own Milky Way, lie massive black holes surrounded by spinning gas. Some shine brightly, with a continuous supply of fuel, while others go …

Debian 11 bullseye released

“After 2 years, 1 month, and 9 days of development, the Debian project is proud to present its new stable version 11 (code name bullseye), which will be supported for the next 5 years thanks to the combined work of …

Designing better batteries for electric vehicles

“As researchers consider materials for solid-state batteries, they also may want to consider how those materials could impact large-scale manufacturing. The urgent need to cut carbon emissions is prompting a rapid move toward electrified mobility and expanded deployment of solar …

DIY Dual Channel Variable Lab Bench Power Supply 30V 10A 300W

“A bench Power supply is a very important piece of equipment that every electronics hobbyist can own. It helps to limit the voltage and current. That is mandatory when were testing circuits, charging batteries, and testing components, as well as …

DIY SMU: Source Measure Unit

“As a lifelong analog EE, I have built and used many DC power supplies starting with an LM309 5V regulator in the late 60’s. Then on to uA723s, various 3 terminal linears, and many switchers. At Analogic in the …
