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 […]
Newly Updated Circuit Projects:
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 […]
How to Make Active Loudspeaker Circuit
In this post I have explained to make an active loudspeaker system circuit for enabling self sustained amplification of any music source that may be directly plugged in to the active speaker box. Introduction With the advent of ultra modern cell phones, now it has become possible to store huge music data and listen to […]
Make this Bass Booster Speaker Box
In this article I have explained the construction of the high bass boost speaker box system, which can be used for reproducing music with heavy bass effect, which can be adjusted with a potentiometer. By: Alfy Mackenzie Most of the affordable hi-fi systems in the market have decent mid-range and treble feedback but do not […]
