A unique mechanical design aspires to remove heat from this LED light bulb’s insides, but you still need to keep external ventilation in mind.

With a 4k1 collector resistor and 16mA drive into the led, the chosen (read ‘cheapest on ebay’) 6N135 is supposed to beat 1.5μs for both turn on and turn off, with typical figures of 90ns and 800ns.

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 ...

A simple way to stabilize the operating temperature of any components that need it. Part 1 shows the purely analog approach, ...

Abstract: An active power-factor correction (PFC) circuit is presented that employs a newly proposed resistor-free zero-current detection (ZCD). While the conventional ZCD requires either a sensing ...

Let’s say you want to blink an LED. You might grab an Arduino and run the Blink sketch, or you might lace up a few components ...

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 ...
