Today I will explain to you how this simplest constant voltage and constant current battery charger circuit works. This circuit is very nice for charging battery safely without damaging it. It has two main jobs, one is limiting high current and second is stopping over voltage. Main Parts Used In Circuit In this circuit we […]

Simplest Windmill Generator Circuit
In this post I have explained how to make a simple windmill generator circuit which can be used for charging batteries, or for operating any desired electrical equipment, all through day and night, free of cost. Solar Panel vs Windmill One of the biggest drawback of solar panel electricity is that it’s available only during […]
Simplest 100 Watt LED Bulb Circuit
In this article I have explained a very simple 100 watt LED bulb circuit using a few high voltage capacitors. The entire circuit could be built at a cost less than $25. I have already discussed many capacitive type of transformerless power supply circuits in this blog, however all these suffers from a couple of […]
Make a Simplest Temperature Indicator Circuit
A very simple temperature indicator circuit can be built by interconnecting a single transistor, a diode and a few other passive components. Using Transistor as a Heat Sensor As we know that all semiconductors have this “bad habit” of changing its basic characteristics in response to ambient temperature changes. Especially basic electronic components like transistors […]
Simplest Piezo Driver Circuit Explained
In the previous post I explained a piezo transducer element and learned how to use it with electronic circuits. In this article we will see how a piezo tranducer can be driven or operated using a simple circuit. As discussed earlier a piezo transducer basically requires a frequency to vibrate and reproduce the required sound. […]
Simplest AM Radio Circuit
The following circuit was taken from an old electronic book, it is indeed a very nice little two transistor radio receiver circuit which utilizes very few components yet is able to produce output over a loudspeaker and not just over headphones. Circuit Operation As can be seen in the given circuit diagram, the design is […]
