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 Analogue Weighing Scale Meter Circuit
Learn a super simple procedure to make a weighing scale meter circuit useful for measuring smaller magnitudes of weight. The Concept The concept is very simple, a light beam is allowed to pass through a linearly colored ribbon and fall over an LDR. The color shade of the ribbon positioned in front of the light […]
7 Simple Continuity Tester Circuits Explained
If you are looking for a simple circuit to test continuity of wires and long conductors, the explained 7 easy to build continuity circuits are the ones which you can try and might fulfill your requirement. What is a Continuity Tester A continuity tester is a device which is used for identifying the correct continuity […]
Simple ESR Meter Circuits Explained
In this post I have explained a few simple ESR meter circuits which can be used for identifying bad capacitors in an electronic circuit without removing them practically from the circuit board. The idea was requested by Manual Sofian… Technical Specifications Do you have a schematic about ESR meter. Technicians recommend me to check the […]
Simple Frequency Meter Circuits – Analogue Designs
The following simple analogue frequency meter circuits can be used for measuring frequencies which may be either sine wave or square wave. The input frequency which is to be measured must be at least 25 mV RMS, for optimal detection and measurement. The design facilitates a relatively wide range of frequency measurement, right from 10 […]
Simple MOSFET Tester and Sorter Circuit
This simple MOSFET tester does a quick job of testing both enhanced mode type N and P-channel mosfets. It checks for shorts between gate, drain and source. Designed By: Henry Bowman It also distinguishes between N and P-channel mosfets. Once the connections are correctly made to the mosfet, all testing is done without reversing connections. […]
