In this post I have explained an automatic submersible pump start, stop circuit with dry run protection in order to implement an automatic ON/OFF switching of the motor in response to the high/low water levels of the overhead tank. Circuit Concept In one of the previous posts I have explained a similar concept which also […]
Newly Updated Circuit Projects:
Generate Electricity from your Gym Workout
In this article I have explained the circuit implementation of an interesting concept of converting physical energy into electricity. Here I have explained a simple method of converting or channelizing the wasted gym workout energy into useful electrical energy. The idea was requested by one of the keen members of this blog, let’s know more: […]
Remote Controlled Toy Car using 433 MHz Remote Modules
This circuit will enable reverse-forward, left-right control of a toy car through 433 MHz RF remote control modules or any similar RF remote modules. The market may be full of these hi-end remote controlled toy cars, but for a hobbyists making one at home can be entirely a different experience. The article below explains how to configure […]
Remote Controlled Pulley Hoist Mechanism Circuit
In this post I have explained a self locking worm gear mechanism for hoisting heavy loads through an electrical motor. The main feature of the system being its self locking in an event of a motor failure. The idea was requested by Mr. Amit Patkar. Technical Specifications I love electronics, especially automation, I have been […]
Stereo FM Transmitter Circuit using IC BA1404
The following posts explains how to build a simple to build FM stereo transmitter circuit using IC BA1404. About the IC BA1404 An exceptional stereo audio FM wireless transmitter circuit is presented below. The circuit relies upon the IC BA1404 from ROHM Semiconductors. BA1404 is a monolithic FM stereo modulator which includes integrated stereo modulator, […]
SPDT Relay Switch Circuit using Triac
An efficient solid state single pole double throw or SPDT switch can be built using triacs for replacing a mechanical SPDT. In this post I have explained a simple solid state triac SPDT relay circuit, using an optocoupler and a couple of triacs, which can be used as an effective replacement for mechanical relays. The […]
