In this article I have explained 7 easy to build DC to DC voltage doubler circuits using a single IC 4049 and IC 555 along with a few other passive components. If you are wondering how a simple IC 555 can be used for making a powerful voltage doubler circuit, then this article will help […]
3 Sound Activated Switch Circuits Explained
In this post I have explained 3 simple sound activated relay switch circuits which can used as a module for any system that might be assigned to trigger by detecting some kind of sound pressure level. Or simply applications such as a voice activated alarm security circuit. 1) Circuit Objective Utilizing this basic sound activated […]
High Efficiency Solar Charger Circuits using Switching Regulators
Solar power or electricity from sun light is so abundant that we can afford to waste it or dissipate it in the form heat. This means that we can use large, high power solar panels to charge batteries with lower power without bothering about how much solar energy is being wasted and how much the […]
DC to DC Converter Circuits using SG3524 [Buck, Boost Designs]
A DC to DC converter is basically a switch-mode power supply, designed to work either as a boost-converter to step-up a low voltage DC to a higher voltage DC, or as a buck-converter to step-down a higher voltage DC to a lower voltage DC. The switched mode conversion ensures that the power transfer in the […]
