A sine wave generator is actually a sine wave oscillator circuit which generates an exponentially rising and falling sinusoidal waveform. The 9 simple sine wave generator circuits presented in the following article are easy to build, since they incorporate a small number of ordinary electronic components, and can be used for generating an exponentially varying […]

Bicycle Generator Circuit
In the following post I have explained a simple circuit idea which can be used for generating free electrical energy for illuminating a few safety flashing LEDs on a Bicycle. The Circuit Concept A bicycle like any other modern vehicle needs provision of lighting system for its use at night or cycling in lesser light. Usually […]
What is an Earth Torque Generator (ETG)? A New Concept for Unlimited Clean Energy
Contributor Credit: This conceptual proposal and the structural framework of the Earth Torque Generator (ETG) have been developed and contributed by Mr. Ike Higgins, continuing his ongoing dedication to introducing public-domain concepts for environmental restoration and planetary healing. Introduction In an effort to continue my quest to get new ideas for technology that will help […]
Simplest Windmill Generator Circuit
In this post I have explained how to make a simple windmill generator circuit which can be used for charging batteries, or for operating any desired electrical equipment, all through day and night, free of cost. Solar Panel vs Windmill One of the biggest drawback of solar panel electricity is that it’s available only during […]
Making a Thermoelectric Generator (TEG) Circuit
A thermoelectric generator (TEG) is a kind of “free energy device” which has the property of converting temperature into electricity. In this post I have explained a little about this concept and find out how we can use it to generate electricity from heat and cold. What’s TEG In one of my earlier articles I […]
Arduino SPWM Generator Circuit – Code Details and Diagram
In this post I have explained how to generate sine wave pulse-width-modulation or SPWM through Arduino, which can be used for making a pure sine wave inverter circuit or similar gadgets. The Arduino code is developed by me, and it is my first Arduino code, …and it looks pretty good 🙂 What is SPWM I […]
