The proposed variable drill speed controller circuit maintains a constant (adjustable) speed over the drill machine motor, regardless of the load. One of the most used power tools is the power drill machine. Despite its innumerable advantages, the power drill has one major setback – constant high speed for many applications. Even when there are […]

5 Simple DC Motor Speed Controller Circuits Explained
A circuit which enables a user to linearly control the speed of a connected motor by rotating an attached potentiometer is called a motor speed controller circuit. 5 easy to build speed controller circuits for DC motors are presented here, first one using MOSFET IRF540, second one using IC 555, the third concept with IC […]
Automatic Curtain Open-Close Circuit
We are happy to share an automatic curtain control circuit kindly provided by Mr. August Peterson. This design helps to open and close curtains by sensing light from the surroundings. It uses an LM393 comparator, a solar panel as a light sensor and a 24V motor. The circuit makes the curtain open in the morning […]
Line Laser Controlled Motor Alignment Circuit
In this post I have explained a simple line laser controlled motor driver circuit, which works by responding to a precision horizontal laser line, generated from a line laser level device, and automatically adjusts the alignment of the connected tool or the job work with extreme perfection and accuracy. What is Line Laser The line […]
Simple 220V AC Fan Regulator Circuit using Push Button
In this post we learn about this 220V AC electronic fan regulator circuit using a push button which changes speed step by step with each press. We press the button, then circuit cleans the signal, counts it properly, and then selects a relevant fixed speed level. Each button press moves the fan from OFF to […]
Operating a DC Motor Clockwise/Anticlockwise with a Single Switch
The following post discusses the wiring connections for driving a DC motor in clockwise and anticlockwise directions with the help of a single toggle switch and a relay circuit. The idea was requested by one the interested followers of this blog. I have explained more: Technical Specifications We have our project in school. Our professor […]
