In this post I have explained an enhanced multi-spark CDI circuit which is universally suited for all types of automobiles. The unit can be built at home and installed in a particular vehicle for achieving greater speed to fuel efficiency. The Circuit Concept The following diagram illustrates an enhanced version of a multi-spark CDI circuit. […]

Over Voltage Protection for Automotive Load Dump
In this post I have explained an over voltage cut-off protection circuit in the form of automotive dump load for protecting sensitive and sophisticated modern automotive electronics from transient DC electrical spikes emanating in vehicle electrical. Transient bus voltages are a significant risk factor to integrated circuits. The maximum breakdown voltage that an integrated circuit […]
Using Single Switch for Fog lamp and DRL Lamp
In this post I have explained an easy method of upgrading your existing car fog lamp switch such that it allows toggling both the fog lamp as well as the DRL lamps alternately, as per the owner’s requirement. The idea was requested by mk karthick. Circuit Objectives Am looking for a circuit which is directly connected […]
Car Warning Tone Generator for Ignition, Headlight, Turn Lights
The circuit explained here is basically a warning signal generator designed largely for automobile application. It triggers a warning signal in a situation when the turn indicator switch is not restored back to its neutral status. The circuit is especially useful for all those cars where the turn indicator system is not supported with an […]
Motorcycle Regulator, Rectifier Tester Circuit
The motorcycle regulator, rectifier tester circuit presented here can be used to test a 6-wire shunt type regulator-rectifiers for a 3-phase charging system of motorcycles. These reg./rectifiers (RR-units) are usually sealed with epoxy and it is considered difficult to find out if the unit is faulty or not. Designed and Written by: Abu-Hafss As the […]
How to Make Car LED Bulb Circuit
Typically all car turn signal lamps are around 12 to 20 watt rated which are traditionally incandescent bulb types and produce much lower light intensities compared to LED lights. Here I have explained how these lamps can be replaced with high efficiency, high intensity car LED bulbs. LED Car Bulb Design The image below shows […]
