A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition ...
Microscopic fibers secretly shape how every organ in the body works, yet they’ve been notoriously hard to study—until now. A new imaging technique called ComSLI reveals hidden fiber orientations in ...
The LED, or light-emitting diode, is very unlikely to fail, and if it does, it goes out slowly over the years. Instead, it's the other electrical bits in LED bulbs that fail and cut off the bulb's ...
Our hacker [Moritz Klein] shows us how to make a minimalist analog drum machine. If you want the gory details check out the video embedded below and there is a first class write-up available as a 78 ...
ESP32 LED Blink (Arduino) This project demonstrates how to blink an LED using an ESP32 microcontroller and the Arduino framework. Goal To blink an LED connected to the ESP32 board: ...
Abstract: Solid-state dc circuit breaker (SSCB) has become a key component for fast fault isolation in high-voltage dc systems. However, their effectiveness often relies on complex series and parallel ...
Abstract: This paper presents a new over-temperature protection circuit applied to automotive LED driver. The circuit generates a reference voltage when the LED driver works within the operating ...
In order for the solenoid point motor to throw the point we need to apply current briefly to an electromagnetic coil. A capacitor discharge unit greatly improves reliability in that it builds up and ...
Microaware’s Sandwizz, a schematic-configurable breadboard, hit 120% of its funding goal on Kickstarter on July 19, 2024. The KiCad freeware schematic capture tool is used to configure an active ...
This simulation feature finds the trend of one or more desired voltage/current values. In this part of the article on DC sweep analysis, we delve into some basic concepts that improve the ...
