In this post I have explained how to make a chasing “WELCOME” display circuit sign board, which illuminates each alphabet sequentially until all the 7 alphabets are lit and then the whole display shuts off, the cycle continues permanently as long as the circuit is powered. Overview I have already discussed a similar concept explaining […]

Sunrise Sunset Simulator LED Circuit
In this post I have explained how to make a sunrise/sunset simulator circuit using LEDs and just a couple of BJTs. The idea was requested by Mr. Jerry Circuit Objectives and Requirements Apparently natural daylight is best for humans in regulating our circadian rhythm. I would like to build an LED lighting circuit to control […]
Beacon Level Indicator Circuit for Combine Harvester Grain Tanks
In this post I have explained a beacon indicator circuit for combine harvester grain tanks. The idea was requested by Mr. John Bosch. Circuit Objectives and Requirements I would like to retrofit the rotating beacon grain tank level indicator system shown below, to my older combine harvester. The particular part of the system I want […]
Corona Effect Generator Circuit
In this post we study regarding what is corona effect and how to make a corona effect generator circuit at home using a CDI coil and a tesla coil configuration. Then idea was suggested by Mr. Sanjoy Corona Treatment for Paper Coating Many many thanks for posting the alternate switching timer circuit as requested. Although […]
Simple Faraday Flashlight – Circuit Diagram and Working
In this article I will show how to construct a Faraday flashlight circuit using only a coil/magnet assembly which requires no battery. It’s not free energy, but it converts oscillatory motion to electricity, which can power the flashlight for a couple of minutes. This flashlight will be useful in emergency situations where no access to […]
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. How LED Bulbs Work We know that our ceiling fans and incandescent bulbs can be easily controlled using triac dimmer switches, and we are quite used to with dimmer switches in […]
