Ok so here we have one simple calculator which can help us to calculate the shunt resistor value that we need to connect across a normal ammeter when we want to use that ammeter to measure high current, more than its actual range. So normally, ammeter can measure only small current, like 1 amp or […]

SMPS Flyback Boost Converter Calculator
This calculator tool supports a Boost Converter Flyback setup which means now the code considers: Corrected turns ratio and primary voltage logic since the flyback works by storing energy during “ON” time and transferring to secondary during “OFF” time. Flyback boost topology where output voltage is higher than input. An accurate duty cycle formula for […]
IR2111 H-Bridge Inverter Circuit with Soft Start
Here we see this circuit diagram which is full H-Bridge using 4 power MOSFETs and 2 IR2111 high side driver ICs. That means this circuit is for making full bridge inverter which converts DC into AC. Power Supply Part We have +600V DC at top rail, written as +600V max. And ground (0V) at bottom. […]
True MPPT Solar Controller Circuit using IC 555
Are you wondering if it was possible to build a very simple MPPT circuit using ordinary parts like IC 555 and IC 741, which would work most efficiently imitating a true MPPT? The answer is yes, it is possible, and we will learn about it details, in the following article. In this design I used […]
Servo Motor Working Explained
We know that servo motors already exist for very long time and we also see that many people use them in many applications. These motors look small but they give big power and also they save lot of energy. So now many people who like electronic things and who want to understand more about such […]
How to Make IC LM339 Circuits
The IC LM 339 is primarily created to compare two input voltages and generate a corresponding output. Having said that, before we try to learn regarding the various LM339 based circuits, it would be important to go through the standard features of the LM339. It is basically a quad comparator IC, meaning we can find […]
