9 Simple Metal Detector Circuits Explained
In this post I have explained 9 simple metal detector circuits using LC tuned concept, magnetic absorption concept, and the beat frequency oscillator (BFO) concept. The BFO technique is considered to be the most accurate and reliable methods of detecting metals. 1) Metal Detector Circuit Using a Single UJT The first metal detector circuit shown […]
Potato Battery Circuit – Electricity from Vegetables and Fruits
In this article I have explained how vegetables can be used for making an organic battery, through an example of a practical potato battery experiment. Alessandro Volta was probably the first man to devise the method and idea of generating electricity from electrolytic solutions. According to his concept, two dissimilar metals when brought in contact […]

5 Interesting Flip Flop Circuits – Load ON/OFF with Push-Button
Five simple yet effective electronic toggle flip flop switch circuits can be built around the IC 4017, IC 4093, and IC 4013. We will see how these can be implemented for switching a relay alternately ON OFF by alternately pressing a single push-button or through touch pads, which in turn will switch an electronic load […]
4 Simple Transformerless Power Supply Circuits Explained
In this post I have explained 4 easy to build, compact simple transformerless power supply circuits. All the circuits presented here are built using capacitive reactance theory for stepping down the input AC mains voltage. All the designs presented here work independently without any transformer, or no transformer. The Transformerless Power Supply Concept As the […]
