The proposed infrared or IR remote control circuit can be used to operate an appliance ON/OFF through any standard TV remote control handset. In this write up I have explained a couple of these simple infrared remote control circuits designed for controlling any given electrical appliance through an ordinary or TV remote control unit. Introduction […]

2 Simple Induction Heater Circuits – Hot Plate Cookers
In this post I have explained 2 easy to build induction heater circuits which work with high frequency magnetic induction principles for generating substantial magnitude of heat over a small specified radius. The discussed induction cooker circuits are truly simple and uses just a few active and passive ordinary components for the required actions. Update: You […]
2 Simple Earth Leakage Circuit Breaker (ELCB) Explained
The discussed Earth leakage circuit breaker diagrams will monitor the leakage current level of the earthing line of your house electrical sockets and will trip the appliances as soon a fault is detected. Here I have explained 2 designs, first using transistors only and the second using IC LM324. Introduction If anything goes wrong with […]
2 Simple Bidirectional Motor Controller Circuits Explored
A circuit which allows a connected motor to operate in clockwise and anticlockwise directions through alternate input triggers is called a bidirectional controller circuit. The first design below discusses a Full bridge or H bridge based Bidirectional motor controller circuit using the 4 opamps from the IC LM324. In the second article I have explained […]
2 Simple Arduino Temperature Meter Circuits Explored
In this article, I will show how to construct a couple of easy Arduino temperature meter circuits which can be also used as a LED room thermometer circuit. The circuit is designed to display the readings in doted/bar LEDs. This project can be implemented for applications where ambient temperature plays a crucial role or it […]
2 Meter Ham Radio Transmitter Circuit
In this post I have explained the complete building procedure of a 2-meter amateur ham radio transmitter circuit, using ordinary electronic components and ordinary test equipment. What is 2-Meter VHF Radio The 2-meter amateur radio band is a section of the VHF radio spectrum, which includes frequencies ranging from 144 MHz to 148 MHz in […]
