The basis of almost everything we discuss here on ExtremeTech is the transistor -- but just above that is a topic that we usually skirt around because no one, even hardcore nerds, really know anything ...

Beeps when hears your whistle, A gadget suitable for key-holders, games etc. Some 20 years ago it was common to see small key-holders emitting an intermittent beep for a couple of seconds after its ...

In the six months that have passed after the last USB-C article has been released, I have thought up a bunch of ways that these articles could have been improved. It’s, of course, normal to have such ...

In the process of brainwave signal extraction and transmission, the TGAM module extracts brainwave signals and converts them to attention value. And the attention information is transmitted remotely ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

The circuit shown in Figure 1 illustrates one of the most basic versions of the buck-boost voltage regulator. An electrical switch is connected in series with the line input to regulate the circuit.

In superconducting circuits, currents can flow without applying any electric field. The role of the electrostatic potential difference required to drive a current in conventional circuits is played ...

HEFEI, CHINA | Xinhua | China’s superconducting quantum computer, similar to the “Zuchongzhi 3.0” model, has been deployed for commercial use, marking a crucial step toward the practical application ...
