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 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 […]
Making a Parasite Zapper Circuit
An interesting electronic parasite zapper circuit shown below was successfully built and tested by my friend Mr. Steven. I have explained more about the proposed circuit. What is a Parasite Zapper The purpose of this device is simple, it is meant to act like a parasite zapper, a DIY electronic device that people say can […]
Making a “Helping Third Hand” for Aiding Soldering Jobs
In this post I have explained a step by step construction of a “helping third hand” unit for assisting PCB soldering jobs in order to make the job much hassle free. The gadget could be very handy especially for the new hobbyists. The project was constructed and submitted by Master Ss kopparthy. I have explained […]
Making a Pyrometer Circuit
To make a furnace temperature meter, the sensing element is required to be particularly robust so that it is able to withstand the extreme high temperatures generally developed in furnaces and ovens. What is a Furnace The circuit of a pyrometer explained here is based on a thermocouple principle which can be used to read […]
Making a Strong RF Discharge Circuit
In this article we study an RF discharge generation concept also called EMP generator capable of producing an intense RF electrical discharge in the air which may have the potentials of paralyzing and permanently damaging all electronic systems in the close vicinity. The idea was requested by Mr. Nidal. Technical Specifications I have seen a […]
