In this post I will explain how to make one full adjustable lighting sequence generator which can control and illuminate many external bulbs through triacs in many different running patterns. We can make it so that user can change and select any sequence pattern easily. We will use Arduino for the full control part. Let […]

Mains AC Xenon Tube Flasher Circuit
In this article I have explained a very simple yet amusing mains operated xenon tube flasher circuit using ordinary electronic components. Circuit Operation The circuit was taken from one of the old elektor electronics magazine and it is indeed a very cute little circuit which may be used for creating high intensity lighting effects during […]
How to Add a Dimmer Facility to a LED Bulb
In this article I have explained how to make an LED dimmer circuit for enabling a dimming facility to any mains operated LEDs bulb. Update: [Using Capacitors, it Works] If you think PWM dimming control might not work for commercial LED bulbs, then the best method is to use series capacitors, which might just do […]
32V, 3 Amp LED Driver SMPS Circuit
In this article I have explained a 32V, 3 amp SMPS circuit which may be specifically used as an SMPS 100 watt LED driver, rated with the same specs. The circuit of the proposed 32 V, 3 amp smps led driver may be understood with the the help of the following points: Circuit Operation The […]
IC 555 LED Circuits (Blinking, Flashing, Fading Effect)
In this post I have explained how to assemble IC 555 for generating interesting LED circuits with blinking, flashing and fading light effects with some minor modification and enhancements. Why use an IC 555 Astable The astable multivibrator mode is the most fundamental mode of operation of the IC 555. In this mode it basically […]
Footstep Activated LED Trouser Light Circuit
In this post I have explained how to transform your ordinary trousers into a chasing LED lit trousers which produces an shooting LED light chasing effect in response to your footstep movement or thumping. The Circuit Concept The proposed foot step activated chasing LED trouser will enable you to decorate any piece of clothing with LEDs […]
