Among the different existing inverter topologies, the full bridge or the H-bridge inverter topology is considered to be the most efficient and effective. Configuring a full bridge topology could involve too many criticality, however with the advent of full bridge driver ICs these have now become one of the simplest inverters one can build. What’s […]

These are designed to automatically control the illumination of a group of appropriately selected LEDs with respect to the varying daylight and after darkness sets in. The first idea was requested by Mr. Amit 1) Sun light […]
2 Useful Energy Saver Solder Iron Station Circuits
In this post I have explained how to build a energy efficient soldering iron station circuit for achieving maximum power saving from the unit, by ensuring that it is automatically switched OFF when not being used for sometime. Written and Submitted By: Abu-Hafss DESIGN#1: OBJECTIVE To design a circuit for solder iron which would not […]
2 Digital Potentiometer Circuits Explained
In this post I have explained a 2 simple, single chip digital potentiometer circuits which can be controlled through a single pushbutton, a dual pushbutton (up/down) or even through external digital (CMOS/TTL) input triggers. 1) About DS1869 Dallastat TM is a rheostat or potentiometer. This unit delivers 64 conceivable consistent tap outputs over the over-all […]
