Up/Down LED Indicator using LM3915
This circuit can be used for moving an LED bar graph in the upward sequence or downward sequence through a couple of push button switches. The concept can be implemented for many other useful applications. Using IC LM3915 In many circuit applications we require a digitally operated control system enabling an upward or downward control […]
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 […]
How to Generate Electricity from Shoe while Walking
In this post I have explained how to generate electricity from our shoe while walking. This electricity can be simultaneously used for charging a cellphone battery. In a few of my previous posts I have explained how simple machines can be efficiently used for extracting free electricity, you may learn more on this through the […]
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 […]
Make this Gravity LED Lamp Circuit
In this article we investigate a free energy device concept in the form of a gravity LED lamp circuit for illuminating an LED through force of gravity. The Circuit Concept Gravitational force is an awesome source of energy, amply available on this planet, and easily accessible, however, nobody yet has been able to convert this […]
