In cars or automobiles, LEDs have grown to be the preferred choice of lighting. Whether it’s the rear tail-lights or the tell-tale indicators in the cluster as indicated in Figure 1 below, all incorporate LEDs nowadays. Their compact dimensions helps versatility in design and offers the prospective to be as durable as the vehicle’s life […]

4 Solid-State Car Alternator Regulator Circuits Explored
The 4 simple car voltage current regulator circuits I have explained below is created as a immediate alternative to any standard regulator and, although developed principally for a dynamo it will function equally effectively with an alternator. If the functioning of a traditional car alternator voltage regulator is analyzed, we find it amazing that these […]
Automobile Engine RPM Servicing Meter Circuit (Analogue Tachometer Circuits)
These useful lightweight, cheap, analogue tachometer circuits are developed for facilitating car or auto servicing mechanics for precisely adjusting a car ignition system RPM to get maximum efficiency from it. The proposed circuits are actually combined results of a tachometer and a dwell meter. Application The car RPM servicing meter circuit can be applied for […]
3-Pin Solid-State Car Turn Indicator Flasher Circuit – Transistorized
Although, most of the car electronics have evolved into solid-sate versions, a turn indicator flasher unit is one device which still depend on a relay based design in many of the modern cars. Disadvantages of Relay Based Flasher There are a couple major disadvantages of a relay based electromechanical flasher unit: 1) First, these being […]
Converting Wasted Spark Ignition to Sequential Spark, for High Efficiency Combustion
In this post I have explained a simple method of converting a wasted spark type ignition system in an automobile, into an enhanced, sequential spark, 6 cylinder engine type ignition system. The idea was requested by Mr. Brenton, as given below: Main Requirements I was looking through the car and motorcycle section but couldn’t find […]
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 […]
