The circuit of a simple 100 watt inverter discussed in this article can be considered as the most efficient, reliable, easy to build and powerful inverter design. It will convert any 12V to 220V effectively using minimum components. However the output AC will be a square wave. Introduction The idea was published many years back […]

Simplest BJT CC, CV Battery Charger Circuit with Trickle Charging (Adjustable)
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. Audio/Video Representation Main Parts Used In Circuit In this […]
Simplest Combination Lock Circuit Explained
A electronic combination lock is a device which is designed to activate an electrical solenoid locking system whenever the correct combination of numbers are entered into an attached keypad. To build this type of electronic combination lock, normally an electronic circuit with a keypad is used. In the design I have explained in this article, […]
Simplest Quadcopter Drone Circuit
In this article I have explained the basics of quadcopter body assembly using aluminum pipes and bolts, in the later sections of the article we will also discuss regarding a simple drone circuit which could be use for flying a small drone assembly without depending on complex microcontrollers. A quadcopter is perhaps the simplest flying […]
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 […]
