Simple Home Automation Circuits
In this article I have explained a few useful yet easy to build home automation circuits which will help the user to create automatic electronic systems at home. What is Home Automation Home automation basically means converting many of the manually operated home electrical devices into automatically operated devices, through electronics. Today’s real home automation […]
2 Simple Automatic Transfer Switch (ATS) Circuits
In this article we investigate an ATS circuit for initiating an automatic changeover from mains supply to generator supply through many intermediate transfer stages which involves activating the fuel valve, choke valve and the generator starter. The circuit was requested by Mr. Hari, and another dedicated reader from this blog. Requirement for 5kva LPG Generator […]
Simple 3 Phase Inverter Circuit
In this post I have explained how to make a 3 phase inverter circuit which can be used in conjunction with any ordinary single phase square wave inverter circuit. The circuit was requested by one of the interested readers of this blog. UPDATE: Looking for an Arduino based design? You may find this one useful: Arduino 3 […]
Simple Digital Stopwatch Circuit (4-Digit)
In this article we’ll study a digital stopwatch design configured around the very popular IC LM555 in conjunction with a 4-digit counter IC with multiplexed 7-segment output drivers (MM74C926). Written and Submitted by: Jennifer Goldy Circuit Operation IC MM74C926 is internally made up of a 4-digit counter, an output latch up stage, a npn output […]
10 LED Simple Roulette Wheel Circuit Diagram
A very simple 10 LED roulette wheel circuit is shown here. pressing the button starts the LEDs in a rotational motion (sequencing) at full swing initially, and gradually slows down, until it stops to a particular, randomly selected LED. The randomness of the selection depends upon the time for which the push remains switched ON […]
