Driving a three phase motor on a single phase supply directly through ordinary methods can be difficult and dangerous. It requires accurately designed circuits for implementing the operations. Here I have tried to present one such PWM controlled three phase motor driver circuit. I have explained more. The circuit can be understood with the following […]

SMS Based Water Supply Alert System
In this post I will show how to construct a circuit which will notify the user via SMS if the water supply to you area / home is initiated. It can show the time when the water is begin to supply and ended, average water flow speed in liter per minute and total water delivered […]
Over Current Cut-off Power Supply Using Arduino
In this post I will show how to construct a battery eliminator / DC variable power supply which will automatically cut-off the supply, if the current flow through the load exceeds the preset threshold level. Main Technical Features The proposed over current cut-off power supply circuit using Arduino has 16 X 2 LCD display, which is […]
How to Design a Bench Power Supply Circuit
In this post I have explained how an effective and efficient, yet very cheap, and stabilized bench power supply can be designed by any electronic hobbyist for safely testing all types electronic projects and prototypes. The main features that a bench power supply must have are: Audio/Video Representation General Description The majority of the power […]
