In this post I have explained a simple 21 watt LED lamp circuit module which can be used as a direct replacement for a standard halogen lamp used in motorcycles headlamp. LED vs Halogen Lamp The proposed “halogen” LED lamp replacement module image can be seen below: Conventional filament type halogen lamp is shown below: […]

Cyclist’s Safety Light Circuit – Nighttime Visibility for Cyclists, Walkers, Joggers
A simple flashing bicycle safety light circuit has been discussed in the following article In many occasions when we happen to go down the road at night, it is normal to meet cyclists that are visible only when they might be within walking distance. In case you’re a bike aficionado and prefer to stroll in […]
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 […]
Make this Car Interior Light Fader Circuit
In this post I have explained a simple circuit which can be used for producing a slow fading light effect each time it’s switched OFF. The application can be typically used in car interior lights. Designed by: Abu-Hafss The Circuit Concept Most of the modern cars are equipped with circuitry which switches on the Car’s […]
Motorcycle Accident Alarm Circuit
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 […]
Arduino Automatic School/College Bell System
In this post I will show how to construct an automatic school bell/college bell system using Arduino, 16 x 2 display and real time clock module. You can program this project to ring the bell up to 16 times a day at your preferred hour and minute. The length of the bell ring can be […]
