Making an EGS002 Equivalent Board using Arduino

Last Updated on June 15, 2025 by Swagatam Leave a Comment

The EGS002 board is nothing but a combination of a microcontroller with a H-bridge driver like the IR2110. So if you are interested to build your own EGS002 equivalent board with exactly identical features, then you can do it using the instructions given in the following article. So, here we are trying to build our […]

Making a Center Speaker Box C80 for Surround Sound Systems

Last Updated on January 19, 2025 by Swagatam 4 Comments

surround sound speakers

A Hi-Fi surround sound system (5.1) typically consists of 4 speakers at the corners of the room, and a center speaker just below or above the TV or the video system. This center speaker becomes the main speaker box of the surround sound since it is responsible for delivering the high quality voice output from […]

Making a Self-Powered Generator

Last Updated on October 5, 2023 by Swagatam 63 Comments

12V battery

A self-powered generator is a perpetual electrical device designed to infinitely run and produce a continuous electrical output which is usually larger in magnitude than the input supply through which it’s running. Who wouldn’t like to see a self-powered motor generator running at home and powering the desired appliances non-stop, absolutely free of cost. We […]

Making a Thermoelectric Generator (TEG) Circuit

Last Updated on October 6, 2019 by Swagatam 13 Comments

TEG

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 […]
