There’s a part you’ll find in almost every mains powered switch mode power supply that might at first appear to have only one application. An optocoupler sits between the low voltage ...

Tito] entered a Self-Charging LED Flasher into the Component Abuse Challenge. It’s a simple re-build of a design by the ...

The code-free LIN LED driver from Melexis makes it easier to develop dynamic RGB-LED automotive ambient lighting designs.

The numbers you see on the box don't always work out in real life. LED bulbs do last longer, but those claims about five to 10 years are estimates based on internal testing -- and companies are always ...

That means inside every LED bulb are tiny circuit components -- and their soldered contact points -- which are far more vulnerable than the diode itself. The Lighting Research Center of the Rensselaer ...

Abstract: Structured light devices are commonly used in many measurements by emitting certain illuminating patterns on objects or scenes, enabling the acquisition of object information. To achieve ...

Abstract: Nowadays, direct current-drive (DC-drive) is the mainstream method of driving electroluminescence (EL) devices such as quantum-dot light-emitting diodes (QLEDs). In contrast, alternating ...

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...
