In this post we’ll try to investigate the making of HHO gas in automobiles for enhancing their mileage by approximately 50% or more, that means a reduction of petrol or diesel consumption by the same amount. In the previous post I tried to put forth an innovative design of a high voltage low current generator […]

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 […]
Flashlight Circuit with Long Backup and High Efficiency
There are two main advantages of this highly efficient flashlight circuit with long backup. Firstly, it uses only a single 1.5V AAA cell and illuminates a 3.3V LED. Secondly, the 1.5V cell is consumed by the LED until there’s virtually no charge left in it. Due to these features, this flashlight is able to last […]
Simple Hi Efficiency LED Torch Circuit
A simple LED torch circuit that would light up 3 white LEDs from a 6 volt supply and would make your battery last forever is described here. A useful voltage doubler circuit is incorporated here to make a highly efficient circuit using just a handful of components. Introduction Learn more how to build it. White […]
High Efficiency Li-Ion LED Driver Circuits Explained
In this post I have explained a high efficiency 1.5 V to 4.2 V LED driver circuits which can be used with a standard Li-Ion battery for enhanced illumination, extended battery backup and long battery life. Main Features Using IC LT1932 The IC LT1932 is a fixed frequency step-up DC/DC converter intended to function as […]
