Although, a 7805 IC is mostly used as a fixed 5 V voltage regulator, it is possible to configure a 7805 IC to produce a variable output from 5 V and higher, depending up the input DC supply. In this post I have explained a simple circuit network which can be used for getting an […]
Newly Updated Circuit Projects:
Digital Step Sine wave Generator Circuit
In this post I have explained how to build a simple yet accurate digital sine wave generator circuit, which is basically an oscillator circuit, enhanced to generate square waves through incrementing steps, which ultimately appears like a stepped sine waveform. By Ron Mackenzy The difference between analogue sine wave generator and digital sine wave generator […]
Firecracker Igniter circuit [Remote Controlled with Timer]
In this post I will show how to construct a few fireworks ignition circuits which can safely ignite them via IR remote and timer. We have proposed three firecracker igniter circuit designs using ordinary components which we will be exploring them in detail. Before we jump in to the circuit details, we have a word […]
Telephone Transmitter Circuit
In this post I have explained how a landline telephone can be rigged up wirelessly with a small transmitter circuit, enabling easy tapping of the telephone, by transmitting the conversations to a distant FM radio appropriately set up for the listening. Circuit Description The circuit diagram for the Telephone Transmitter can be witnessed in the […]
Municipal Water Supply Sensor Controller Circuit
In this post I have explained a simple water sensor with pump starter circuit for switching a pump motor during municipal water supply periods. The idea was requested by Mr. Hitesh Thapa. Technical Specifications Is it possible to make a automatic water pump starter which turns On only when the city supply line has water […]
Types of Solar Panels, Solar Inverters Explained
In this article I have explained the main types of solar panels available in the market, and also discuss the different types solar inverters which are specifically compatible with these solar panels. Further in the article we will also discuss how the efficiency of a solar panel may be affected due to to bad weather, […]
