When the lights go out, the way you string together a few cords can quietly decide whether your home stays safely powered or ...

UNIST scientists turn raindrops into electricity using carbon fiber rooftops to power smart drainage and flood warnings.

A team of European scientists has developed a way to generate electricity from triboelectrification, a process historically ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

It’s always a pleasure to find a hardware hacker who you haven’t seen before, and page back through their work. [Bettina Neumryr]’s niche comes in building projects from old electronics magazines, and ...

Nickel Cadmium (NiCd) batteries are widely used in consumer electronics due to their high energy density and long life. Constant current charging is often recommended by manufacturers. Several ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

This year's Atlantic hurricane season officially started June 1, and it could see above-average activity. The National Oceanic and Atmospheric Administration is predicting 13 to 19 named storms by the ...

Abstract: Most analog circuits need a current reference generator to provide a stable biasing point for the transistors. Given the limited voltage headroom in advanced node technologies, there would ...
