In this post I will show how to construct a circuit which can measure the speed of any vehicle on roads and highways. The proposed circuit is kept stationary at a place where the vehicles are suspected to over-speed. If any vehicle goes beyond the speed limit, the circuit alerts immediately. We will be looking […]

Automatic Vehicle Headlight Dipper/Dimmer Circuit
The circuit described here can be built and used in your vehicle for an automatic dipping and dimming operation of the vehicle headlamps, in response to the intense lights coming from an opposite vehicle headlamps. What’s a Dimmer/Dipper in Automobiles An automobile headlight dimmer/dipper is a circuit which automatically switches the headlight intensities of vehicles arriving from […]
Vehicle Immobilizer Circuit Explained
If you own a car and still haven’t incorporated any security system in it or perhaps your old security system is out of order, you can quickly opt for a cheap yet effective security option for your car or any vehicle by installing the proposed circuit. It will cost you not more than a dollar. […]
Vehicle Speed Limit Alarm Circuit
In our previous articles we have learned comprehensively regarding the ICs LM2907/LM2917 which are fundamentally frequency to voltage converter ICs, and are ideally applicable in all such relevant fields. Here we see how the same chip can be applied for making a vehicle speed limit alarm circuit. Using a Single IC for Speed Detection As […]
Vehicle Body Metal Detector Circuit
The main objective we are trying to achieve with this vehicle body metal detector is that only an automobile can trigger the opening of the gate. The solution involving the interruption of a light beam is not suitable, so we turned to a metal detector, as metal is a primary material in any automobile. In […]
Designing a Powerful 48V 3KW Electric Vehicle
In this post I have explained a few important parameters related to the making of a 48V 3KW electric vehicle using solar panel, including a full fledged circuit diagram for the same. The idea was requested by Mr. Sreejith. Circuit Objectives and Requirements I am Sreejith Rajan a b.tech student doing a project on electric […]
