In this post I have explained how to make a simple electric wheelchair circuit using a standard BLDC motor driver circuit, and a couple of high power BLDC motors. Introduction The introduction of electric wheelchair was like a boon to our many differently-abled friends who now find it much easier to move and travel around, […]

High Current Sensorless BLDC Motor Controller using Back EMF
In this post I have explained a high current sensorless BLDC motor controller circuit which does not depend on hall effect sensors for initiating the operations rather utilizes the back EMF from the motor for the sequential input Overview For proper commutation most 3-phase BLDC driver circuits rely either on a sensor based feedback or […]
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 […]
200, 600 LED String Circuit on Mains 220V
In this post I have explained the construction of a 200 to 600 LED circuit project, using series parallel LEDs for creating an alphabetical display sign board. The idea was requested by Mr. Mubarak Idris. Circuit Objectives and Requirements I need a blinking LED light that show”WELCOME TO” blink and then “COLLEGE OF ENGINEERING” base […]
Inverter Voltage Drop Issue – How to Solve
Whenever PWM is employed in an inverter for enabling a sine wave output, inverter voltage drop becomes a major issue, especially if the parameters are not calculated correctly. In this website you might have come across many sine wave and pure sine wave inverter concepts using PWM feeds or SPWM integrations. Although the concept works […]
Transformerless AC Voltmeter Circuit Using Arduino
In this article I have explained how to make a transformerless AC voltmeter using Arduino. Making an analog voltmeter is not an easy task as to build one you must have good knowledge of physical quantities like torque, speed; which can be very difficult when it comes to their practical applications. By Ankit Negi But […]
