In this post I will comprehensively explain what logic gates are and its working. We will be taking a look at the basic definition, symbol, truth table, Multi input gates, we will be also constructing transistor based gate equivalents and finally we will take an overview on various relevant CMOS ICs. What are Logic Gates […]
Newly Updated Circuit Projects:
Capacitor Leakage Tester Circuit – Find Leaky Capacitors Quickly
This simple capacitor tester is capable of testing leaky electrolytic capacitors in the range of 1uf to 450uf. It can test large start and run capacitors as well as 1uf miniature capacitors rated at 10v. Once you understand the timing cycle, you can test down to 0.5uf and up to 650uf. By Henry Bowman How […]
How to Make Step Down Transformers
A step down transformer is a device which reduces a higher AC potential to a lower AC potential as per its winding ratio and specifications. In this article we are going to discuss how to design and construct a basic step down transformer which are typically applied in mains-operated power supplies. Introduction This will likely […]
Digital Weighing Scale Using Load Cell and Arduino
In this post I have explained about strain gauge based load cell. We will be exploring what Strain Gauge is, what Load Cell is, temperature effect on strain gauge, temperature compensation with Wheatstone bridge and Load cell amplifier HX711, and finally I have explained how to build an Arduino based weighing scale machine by implementing […]
3 Phase Solid State Contactor Circuit: Electronic ON/OFF for Motor Pumps
In this article I have explained how to design and build a solid state contactor circuit using triacs, with ON OFF push electronic switches, for operating heavy duty loads like submersible borewell pump motors with high reliability, and without any concerns about wear and tear issue or long term degradation issues of the contactor unit. […]
PIR Solar Home Lighting Circuit
In this post I have explained a simple circuit using Passive Infrared or PIR for making an automatic solar LED lamp which can be used for illuminating your home automatically at sunset, and only in the presence of a human member in the premise. By SS Kopparthy Introduction Here, in this article, I will discuss a […]
