Ice Warning Circuit for Automobiles
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)
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 […]
