Make this DC CDI Circuit for Motorcycles
The circuit presented here is for a DC-CDI which are used in motorcycles. A DC-CDI is the one in which the high voltage (200-400VDC) is converted from 12V supply voltage. Researched and Submitted by: Abu-Hafss Studying the circuit, we see that it has two parts i.e. the CDI unit, enclosed in the pink box and […]
Darkness Triggered Car Safety Park Light Circuit
In this post I have explained a circuit concept for enabling cars with an add-on automatic safety park light which triggers during night and signals the position of the car and consequently prevents a mistaken collision or dashing by another vehicle. The design ensures minimum consumption and relatively higher brightness for the involved LED lights. […]
