Simple Ni-Cd Battery Charger Circuits Explored

Last Updated on January 2, 2024 by Swagatam 116 Comments

Nicd Charger circuit

In this post I have explained many simple NiCd charger circuits with an automatic overcharge protection and a constant current charging. When it comes to correctly charging a Nickel-Cadmium cell, it is strictly recommended that the charging process is halted or cut off as soon as it reaches the full charge level. Not following this […]

Remote Control using Mains Power Line Communication

Last Updated on May 12, 2023 by Swagatam 44 Comments

main communication reciever

The proposed circuit will allow you to remotely control a mains AC operated appliance across rooms of your home through mains power line communication or PLC concept. In PLC technology, an electronic circuit which works as a transmitter is plugged-in to the mains wiring (220 V or 120 V) injects a modulating high frequency data […]
