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 […]
How to Make Any Light a Strobe Light Using Just Two Transistors
If you feel strobe lights very interesting but are disappointed by the fact that these wonderful light effects can be produced only through complex xenon tube then probably you are quite mistaken. It is very much possible to make any light a strobe light if you are equipped with a proper driving circuit capable of […]
Diwali, Christmas 220V Lamp Chaser Circuit
In this post I have explained a simple, compact, 220V, 120V transformerless light chaser circuit which can be used for illuminating 220 V mains operated lamps or bulbs in a sequential chasing manner. Main Technical Features The chasing or running lamp effect can be altered by means of pot controls. The system can be used […]
Make an Electronic Candle at Home Circuit
The proposed electronic candle circuit does not use wax, paraffin or flame, yet the device perfectly simulates a conventional candle. Basically it incorporates ordinary electronic parts like LED and battery. The interesting part of it is that it can be extinguished with literally a puff of air. The proposed electronic LED candle circuit helps you […]
LED Fader Circuit – Slow Rise, Slow Fall LED Effect Generator
In the following post I have explained a simple circuit which can be used for alternately switching LEDs with gradual brightening and fading effects. Circuit Operation The circuit can be effectively used for generating spooky effects in idols, for example it can be used for illuminating the eyes of a Jack-o’-lantern during haloween celebrations. The […]
