Mp3 Player Using DF Player – Full Design Details
In this post I will show how to construct an Mp3 player using arduino and DFPlayer. The proposed article has two Mp3 player designs, one with push button control and another one with IR remote control. We will also take a look at DFPlayer (Mp3 player module) and its specifications. We all love music, we […]
Calculator to Design a High Power 3kW PFC (Power Factor Correction) Circuit
In this post I will explain how to use this active PFC calculator for calculating high current, high PFC designs. In our example we will be using 230 VAC input and 3 kW output and Vout equal to around 390 V, and we will try to see how each resistor and capacitor gets calculated in […]
Design your own Sine Wave Inverter Circuit from the Scratch [Tutorial]
In this article I have explained comprehensively regarding how to design a sine wave inverter without any form of coding or complex circuit designs. The included designs are simple yet extremely precise with their sine waveform structure. You might have often felt discouraged, thinking that making a sine wave inverter from the scratch can be […]
How to Design Customized 220V SMPS Circuits
We many times think that how we can make a SMPS circuit, and we feel that this is very complex. But that is not so because we can do this by following simple manual calculations step by step. We only need to know that SMPS design is always starting from the transformer. We cannot make […]
How to Design Simple LED Driver Circuits
In this article I have explained how to design your own customized, simple LED driver circuits at home. We will learn how to calculate specific LED configurations for applying the LEDs with appropriate LED driver power supplies. In these driver power supplies I have explained two concepts one by using SMPS boards and the other […]
