Many a times we find it crucial and handy to possess a true three phase signal for evaluating many different electronic configurations such three phase inverters, three phase motors, converters etc. Since it’s not so easy to incorporate single phase to three phase conversion quickly we find this particular implementation difficult to acquire and enforce. […]

Transistor based 3 Phase Sine Wave Generator Circuit
In this post I have explained a very simple 3-phase sine wave generator circuit, using only three bipolar transistors and a few passive components for initiating the desired three phase output. How it Works Referring to the 3 phase sine wave generator circuit we can see three identical transistor stages configured in a cross coupled […]
Cellphone Charger Circuit Using Pendulum Generator
This pendulum electricity generator can be used in villages for charging cellphones free of cost just by applying momentary pushes to the pendulum frequently or as desired throughout the day. Pendulum as Free Electricity Generator In one of my previous articles I explained about the high efficiency value of a pendulum mechanism, and how it […]
Real Machine Gun Sound Effect Generator Circuit
Video Demonstration An impressive little machine gun sound effect generator circuit is discussed here. Once built can be integrated with any audio amplifier to experience a roaring bullet studded war like simulation. A small hobby project which can be tried by all electronic enthusiasts will generate interesting machine gun sound effect over the connected loudspeaker, […]
Make a Football Electricity Generator Circuit
The explained football electricity generator circuit was developed by me in response to the request sent by one of the readers Mr.Bright. Though I am not sure if the explained concept would actually give the intended results, it’s worth trying as it’s quite easy to understand and build. Designing the Generator There were three things that I had to consider while designing the […]
Simple High voltage Generator Circuit – Arc Generator
A simple high voltage generator circuit is explained here which can be used to step up any DC level to about 20 times or depending upon the transformer secondary rating. Circuit Operation As can be visualized in the shown high voltage arc generator circuit diagram, it employs a standard transistor blocking oscillator configuration for generating […]
