Adjustable CDI Spark Advance/Retard Circuit
In this post we’ll learn about a simple circuit which allows a manual adjust feature for the spark timing of a motorcycle’s CDI either to achieve an advance ignition, retarded ignition or simply a normal timed ignitions. After a comprehensive study regarding the subject I was apparently successful in designing this circuit which can be […]
How to Make HHO Fuel Cell Circuit in Automobiles for better Fuel Efficiency
In this post we’ll try to investigate the making of HHO gas in automobiles for enhancing their mileage by approximately 50% or more, that means a reduction of petrol or diesel consumption by the same amount. In the previous post I tried to put forth an innovative design of a high voltage low current generator […]
Car Blown Brake Light Indicator Circuit to Detect Broken Bulb Filament Tail Light
In this post I have explained a simple fused or blown car brake light indicator circuit using a single IC 555 and a few other passive components. The idea was requested by Mr. Joel Bayongasan Technical Specifications You innovations are great! Thanks for this blog. May I request something please? I was searching for a […]
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 […]
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 […]
