Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

TI has remained remarkably quiet about its latest precision voltage reference IC: REF81. It is a modified form of the equally quietly released REF80, which is a temperature-controlled buried Zener ...

A series where we find out which products the professionals (who really know what they’re talking about) actually use and really stand behind. Read more here. Maybe you’ve seen an influencer gliding ...

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 ...

Electricity doesn’t just flow freely in every direction—it needs control. That control comes from a tiny but powerful component: the diode. In this video, you’ll learn how diodes work, why they allow ...

This video explains what a diode is and how it controls the direction of current in electronic circuits. Diodes allow current to flow in only one direction, making them essential for rectification, ...

If LED masks seem like an unnecessary beauty luxury, skin experts say that there's proven science behind the trendy at-home treatments. While some are used to target specific skin concerns, others ...

There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...

Light-emitting diode (LED) light therapy is a cosmetic and medical treatment that uses LED wavelengths to treat various skin conditions, such as acne and psoriasis. You can get this therapy at a ...
