In this article we now talk about a very simple but very useful stepper motor controller that uses one A4988 driver module and one 555 astable pulse generator. Overview Of The Circuit So we first see the main building blocks. We have one A4988 module that drives any small 2 phase stepper motor. We also […]

Build this Unidirectional Wind Turbine: Wells Turbine
In this article I will explain you the full step by step building guide for making one Wells turbine at home, which is intended specially for homemade sea wave electricity system using oscillating air column. What is Wells Turbine So first we must understand that wells turbine is a special type of turbine in which […]
How to Control a Servo Motor using IC 555
In this project I have explained the basic specifications of a servo motor and also how to control a Servo Motor using a 555 timer IC, and just two push buttons. WHY SERVO? Servo Motors are used in variety of fields. These are mainly used as actuators in those areas where we need a precise […]
Servo Motor Working Explained
We know that servo motors already exist for very long time and we also see that many people use them in many applications. These motors look small but they give big power and also they save lot of energy. So now many people who like electronic things and who want to understand more about such […]
AC Motor Speed Controller Circuits using Back EMF
In this post I have explained a few circuit diagrams for building AC motor speed controller circuits using back EMF concept. Working Principle of AC Motors So now, all those home type appliances like electric drill machines, sander machines, sewing machines, food mixer machines, etc. they all are mostly using that AC motor which is […]
Universal ESC Circuit for BLDC and Alternator motors
In this post I have explained a universal ESC circuit or an electronic speed controller circuit which can be universally applied for controlling any type 3 phase BLDC or even an alternator motor. What is an ESC An ESC or electronic speed controller is an electronic circuit which is normally used for operating and controlling […]
