How to Make Powerful Car Headlights Using LEDs
In this post we see how to build an enhanced and efficient car headlight lamp using Pirhana LEDs. A car LED headlight is a powerful lamp built using high efficiency LED arrays, which creates extremely powerful headlight lamp for the car, along with a very high efficiency in terms power consumption. Using 4-pin Pirhana LEDs […]
Simple Capacitive Discharge Ignition (CDI) Circuit
In this post I have explained the circuit for a simple, universal capacitive discharge ignition circuit or a CDI circuit using a standard ignition coil and a solid state SCR based circuit. For an audio/video explanation, you can watch the following video representation: How Ignition System in Vehicles Work The ignition process in any vehicle […]
2-Pin Motorcycle Turn Signal Flasher Indicator Circuit with Buzzer
A simple construction procedure of a motorcycle electronic 2 pin turn signal indicator with beeper circuit has been thoroughly I have explained in this article. Normally, the electro-mechanical types of turn signal indicators are not reliable due to low consistency and vulnerability to changing weather conditions. The present design easily withstands the above parameters and […]
