In this article I will try to explain how scalar control algorithm is implemented for controlling induction motor speed with relatively straightforward calculations, and yet achieve a reasonably good linearly variable speed control of the motor. Reports from many top market analysis reveal that induction motors are the most popular when it comes to handling […]

Solid State Contactor Circuit for Motor Pumps
In this article I have explained how to design and build a solid state contactor circuit using triacs 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. What is a Contactor A contactor […]
Color Detector Circuit with Arduino Code
In this post I will show how to construct a circuit which can detect color and trigger respective assigned relays. This project is accomplished using TCS3200 color sensor and Arduino board. Color Sensing by TCS3200 If you haven’t read the previous article, please go through it where we have discussed the basics of color sensing […]
Wireless Servo Motor Control Using 2.4 GHz communication link
In this post I will show how to construct a wireless servo motor circuit which can control 6 servo motors wirelessly on 2.4 GHz communication link. Introduction The project is divided into two parts: a transmitter with 6 potentiometers and a receiver circuit with 6 servo motors. The remote has 6 potentiometers to control 6 […]
2.4 GHz 10 Channel Remote Control Switch
In this post I will show how to construct a 10 channel remote control switch based on ISM (industrial, Scientific and Medical) band. Introduction The ISM band is operated at 2.4 GHz, which can be used without licensing with reasonable power output. The proposed project is general purpose ON/OFF wireless switch, which can be […]
0-40V Adjustable Power Supply Circuit – Construction Tutorial
This multipurpose general purpose supply generates as much as 2.5 amps from zero to 20 volts or up to 1.25 amps from 0-40 volts. Current limiting is variable within the entire range for either output options. By Trupti Patil Power Supply Main Specifications: AN IDEAL POWER SUPPLY must provide a voltage that is variable within […]
