Motorcycle Regulator, Rectifier Tester Circuit

Last Updated on May 16, 2026 by Swagatam 1 Comment

The motorcycle regulator, rectifier tester circuit presented here can be used to test a 6-wire shunt type regulator-rectifiers for a 3-phase charging system of motorcycles. These reg./rectifiers (RR-units) are usually sealed with epoxy and it is considered difficult to find out if the unit is faulty or not. Designed and Written by: Abu-Hafss As the […]

Remote Controlled Fish Feeder Circuit – Solenoid Controlled

Last Updated on January 4, 2024 by Swagatam 27 Comments

fishfeeder

In this design a solenoid is operated using an IR remote control, which in turn toggles the fish feeder mechanism. In this article I have explained how to make a simple infrared controlled fish feeder circuit. The idea was requested by Mr. Harishvar. Technical Specifications I just want a circuit which should turn on when […]

Borewell Motor Pump Starter Controller Circuit

Last Updated on June 30, 2026 by Swagatam 53 Comments

dry2Brun

In this post I have explained a circuit which controls a submersible borewell motor by operating its red (Start) and green (Stop) buttons, in response to low level, high level water conditions, and also in a condition where the motor may experience a dry run situation. The idea was requested by Mr. Vamsi. Automatic Start/Stop […]
