In this post I have explained how to make an useful motorcycle accident alarm circuit for sending alarm signal to the distant population in an event of an accident, especially if it happens in a relatively lonely area. The idea was requested by Mr. Rayan D’souza. Circuit Objectives and Requirements I want a circuit that […]

Speed Dependent Brake Light Circuit
In this post I have explained an innovative brake light circuit using speed detection of the vehicle which could be a motorcycle. The circuit implements an advanced brake light switch ON ensuring a much safer riding experience for the user. The idea was requested by Mr. Rayan. Circuit Objectives and Requirements I have an idea, […]
Solar E Rickshaw Circuit
In this post I have explained a simple solar electric rickshaw or E rickshaw circuit which can easily built by anybody at home and used with a locally fabricated vehicle. The idea was requested by Mr. Amit. The Design Selecting a BLDC In one of my earlier posts I presented an idea which could be […]
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 […]
SMPS DC CDI Circuit for Motorcycles using Ferrite Core Transformer
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 smps CDI unit, enclosed in the pink box […]
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. […]
