In this post I have explained an effective PWM motor soft start circuit which can be used for enabling heavy motors with a soft start and thus prevent the equipment from drawing dangerous high currents. Why a Soft Start High wattage motors such pump motors or other forms of heavy industrial motors tend to draw […]
Newly Updated Circuit Projects:
Non-Contact Cable Tracer Circuit
In this post I have explained a simple non-contact cable tracer circuit which can be used for locating faults in long wound cables and wire bundles without a physical contact. The Circuit Concept Why would you shred $100 to buy a cable tracer when it is easier to develop one spending less than $10! This […]
Make this Solar Powered Fence Charger Circuit
A Fence charger or energizer is an equipment which is used for charging(electrifying) a fence or a boundary in order to protect the inside premise from human or animal interventions. Since these boundaries are mostly of large fields and parks, are normally away from the main cities, and powering them through some renewable option becomes […]
How to Make a GHz Microwave Radar Security Alarm Circuit
In this post I have explained a GHz microwave radar security alarm circuit which is designed to detect an intruder within the critical zone only while it’s moving, static objects produce no effect for the sensor. Using Doppler Sensor KMY24 In the previous article I have explained about a microwave Doppler radar sensor module KMY […]
Make a Walkie Talkie Circuit using FM Radio
In this post I have explained how to make a simple homemade walkie talkie circuit using ordinary FM transmitters and FM radios. It’s a perfectly tested design by me. I could talk with my nephew who stays on first floor through a pair of these transmitters with crystal clear transmission. Overview In one of my […]
Homemade Solar MPPT Circuit – Poor Man’s Maximum Power Point Tracker
MPPT stands for maximum power point tracker, which is an electronic system designed for optimizing the varying power output from a solar panel module such that the connected battery exploits the maximum available power from the solar panel. Introduction NOTE: The discussed MPPT circuits in this post do not employ the conventional control methods like “Perturb and […]
