An Electrolytic Capacitor-Less AC-DC LED Driver with a Low Power Processing Auxiliary Circuit and Ceramic Capacitors for Ripple Power Decoupling

Abstract: Traditional ac-dc LED drivers include a large electrolytic capacitor to decouple the double-line frequency ripple power from the utility grid, which shortens the lifespan of LED lamps. This ...

Workbench: Build an LED Fixture Dimmer Circuit

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

A simple flip-flop LED blinking circuit using NPN transistors, resistors, capacitors, and LEDs.

This project is a basic flip-flop (astable multivibrator) circuit that alternately blinks two LEDs using two NPN transistors, capacitors, and resistors. The circuit uses capacitor charging/discharging ...

LED flasher circuit

With cycling safety in mind, I bought a pair of low power red LED things that replace the bungs in the end of drop handlebars. They are a neat way to get a bit of extra visibility – and to give a ...
