How to Make HHO Fuel Cell Circuit in Automobiles for better Fuel Efficiency

Last Updated on January 21, 2026 by Swagatam 176 Comments

HHO2Bgas2Bin2Bmotorcycle

In this post we’ll try to investigate the making of HHO gas in automobiles for enhancing their mileage by approximately 50% or more, that means a reduction of petrol or diesel consumption by the same amount. In the previous post I tried to put forth an innovative design of a high voltage low current generator […]

Ice Warning Circuit for Automobiles

Last Updated on January 2, 2024 by Swagatam 8 Comments

car ice frost warning circuit

Devices that react to variations in atmosphere or fluid heat are simple to construct due to the easy availability of thermistors. This car ice warning circuit explains how to implement a thermistor like a transducer in a circuit that continuously blinks a warning lamp as soon as the atmospheric temperature drops to around 0 °C. […]

Regenerative Braking System in Automobiles (Circuit Diagram)

Last Updated on June 9, 2021 by Swagatam 8 Comments

car

The following regenerative electricity generator circuit in cars and motorcycles was inspired from the oscillating dolls, and idols inside vehicles which may be seen constantly swaying and moving due to the vehicle’s uneven motion or whenever brakes are applied. How Energy is Wasted in Vehicles During Braking Whenever a vehicle is stopped or braked, a […]
