This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

A blast from the Elektor archives: this clever 1998 battery tester uses a simple LED display to reveal a battery’s true condition under load — even below 1 V. Built from standard components and no ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

I don’t know about you, but although I like reading about electronics in a theoretical sort of way, there’s nothing I enjoy more than the hands-on building of something and then watching that thing ...

Forward-looking: Downscaling has long been the driving force in technological progress – from boosting computing power through smaller transistors to advancing display technology with micro-LEDs. Now, ...

TL;DR: This adjustable LED Lamps clip onto flat monitors, and they’re only $34.99 (reg. $59). A little ambience goes a long way. These LED Monitor Lamps are a quick and dramatic way to turn a regular ...

CCFL backlights are the most common backlight technology and are used in displays ranging from 5.7 to 23 in. or more diagonal. They can have from one to 24 or more lamps mounted along the edge of the ...

LEDs with low polarization in a direction similar to standard LEDs show greater efficiency at higher power by resisting 'efficiency droop', a new study shows. The findings open the door to a new ...

British inventors began experimenting with electric lighting in the 1830s, working on so-called arc lamps, while other scientists around the world focused on developing a functioning incandescent lamp ...
