How to Generate Electricity from Sea Waves – 2 Simple Methods

Last Updated on January 21, 2026 by Swagatam 4 Comments

seawaterelectricity

In this post we investigate a couple of quick and efficient methods of generating free electricity from the sea waves which is limitless and an infinite source of energy. Introduction Just like wind and sun, sea is another example of massiveness and a potential raw energy source that may be harnessed for acquiring electrical power. […]

Advanced SMPS Flyback Transformer Calculator for High Power Converters

Let’s say you are trying to make one flyback transformer for our project, but we are not knowing how many turns we should put, what thickness of wire we should use, what current will flow in primary and secondary, what is the duty cycle, and also how much inductance is needed in the primary winding. […]

Buck-Boost Converter Calculator

Now we made this simple online calculator tool so that we can easily calculate all the important working parameters of this universal buck-boost converter circuit just by putting some basic values like input voltage, output voltage, output current, switching frequency, and inductor size. This tool is directly based on how a real universal buck-boost converter […]

Real MPPT Solar Charger Circuit Using Arduino, LCD, and Manual/Auto Switch

Last Updated on May 19, 2025 by Swagatam 13 Comments

So in this article we are trying to make a true MPPT solar charger project using Arduino which will charge a 12V battery from a solar panel and will use MPPT logic to always extract maximum power from the solar panel. That means that even when sunlight changes, we try to adjust PWM duty cycle […]
