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 radiant 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. 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 […]
Fish Aquarium Oxygen Generator Circuit
In this article I have explained how to make a simple fish aquarium oxygen generator circuit using the concept of electrolysis of water. Generating Pure Oxygen The production of oxygen through electrolysis can be expected to supply a pure and a bigger quantity of oxygen compared to the usual pumped air concept which injects only […]
Illuminating an LED using Wireless Power Transmission
In this post I have explained how to illuminate an LED using wireless power transmission. Wireless Power Technology Wireless power is an emerging technology in this present world. But the stunning fact is that it’s a century old concept. This concept was emerged by Nikola Tesla. Charging batteries through wireless power is used in many […]
