In this post I have explained how to construct a police, ambulance or a fire truck siren circuit using evergreen IC 555 timer and we will also learn how to build a revolving beacon light without any mechanical parts. The proposed project is divided into two parts the siren circuit and the rotating beacon light, […]
Newly Updated Circuit Projects:
Firecracker Igniter circuit [Remote Controlled with Timer]
In this post I will show how to construct a few fireworks ignition circuits which can safely ignite them via IR remote and timer. We have proposed three firecracker igniter circuit designs using ordinary components which we will be exploring them in detail. Before we jump in to the circuit details, we have a word […]
Vehicle Parking Lot Counter Circuit
In this post I have explained how to construct a vehicle counter circuit that can count the number of vehicles entered in a parking lot at office building, schools, libraries, restaurants, hotels etc. The proposed project can count up to 999 vehicles especially cars and two wheelers and it can even count long vehicles like […]
Wireless DC Motor Speed Control Circuit
In this post I will show how to construct a wireless DC motor speed control circuit which can be controlled using any IR based remote controller. The proposed project has two main objectives; the first one is 5 step sequential speed control of a 12V DC motor using IC 555 (PWM) and controlling the PWM […]
3v, 4.5v, 6v, 9v, 12v, 24v, Automatic Battery Charger Circuit with Indicator
An all-in-one automatic voltage battery charger circuit is discussed in the following post; the circuit can be modified in many different ways as per individual requirements and applications. The following circuit will allow you to charge any battery right from 1.5V to 24V simply by setting up a given preset. How it Works using LM3915 […]
High Voltage Battery Charger Circuit
In this post I have explained a simple automatic High Voltage Battery Charger Circuit which can be used for an automatic charging control of any preferred high voltage battery bank such as a 360V battery bank. The idea was requested by “resonance”. Circuit Objectives and Requirements I found all your circuit and projects interesting but […]
