Visitor counters are usually installed at the entrance and exit points of commercial buildings such as shopping malls, theme parks, museums, Airports, schools, departmental shops and other business etc. The registered counts on the machine are used for business […]
Newly Updated Circuit Projects:
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 […]
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 […]
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 […]
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 […]
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 […]
