In this post I will talk about 6 easy yet accurate capacitance meter circuits using the ubiquitous IC 555 and many other easily available ICs. How Capacitors Work Capacitors are one of the main electronic components which come under the passive component family. These are extensively used in electronic circuits and virtually no circuit can […]

Simple Crowbar Circuits for Over-voltage Protection
A handful of simple DC over voltage protector crowbar circuits are discussed in this article. I have explained the working of each crowbar circuit through the following explanation. What is Crowbar Circuit If you are wondering what is a crowbar circuit, the definition is simple. It is a circuit network where a transistor or an […]
Simple 12V, 1A SMPS Circuit
In the following content I have explained two simple 12V, 1 Amp switch mode power supply (SMPS) circuit using the very reliable VIPerXX IC from ST microelectronics. With the advent of modern ICs and circuits, the age old iron transformer type of power supply are surely becoming obsolete. Today power supplies are much compact, smaller […]
Simple IC Tester Circuit [Test Digital and Analogue ICs]
The IC Tester is simple to use. You don’t have any switches to configure or lengthy test processes to complete. The universal IC Tester is a static tester, which means this does not dynamically test the IC’s operation. All ICs with up to 20 pins can be tested by this unit. ICs with more than […]
Simple Buck Converter Circuits using Transistors
In this post I have explained some basic facts about DC to DC buck converters and also learn how to build a simple buck converter circuit. A buck converter is also popularly known as a step-down converter, since its basic function is to step down a higher input voltage level to a lower output voltage […]
Simple LED Forward Voltage Drop Tester Circuit
Semiconductor LEDs (Light Emitting Diodes) produce light when current flows through them. In comparison to conventional lighting sources, LEDs offer a number of benefits, including high energy efficiency, extended longevity, and low thermal output. The forward voltage drop of an LED is one of the important factors that affects how well leds performs. We will […]
