In this post I have explained a simple 5 V to 10 V converter circuit which can be used in TTL circuits where only 5 V is available and converting this 5 V to 10 V can be extremely useful for operating an adjacent circuit which may require a supply of around 9 V or […]

Comparator Circuits using IC 741, IC 311, IC 339
The basic function of a comparator circuit to compare two voltage levels at its input pins and produce an output to show which input voltage has higher potential than the other. In this article we will elaborately learn how to correctly design comparator circuits using popular ICs like IC 741, IC 311 and IC LM339 […]
How to Make a Digital Voltmeter, Ammeter Module Circuits
In this article I have explained how to build a digital voltmeter and a digital ammeter combined circuit module for measuring DC volts and current through different ranges, digitally. Introduction Electrical parameters like voltage and current are inherently associated with electronics and with electronic engineers. Any electronic circuit would be just incomplete without appropriate supply […]
Timer Circuits with Auto Pause and Memory During Power Failures
In this post we try to investigate a couple of innovative solutions which could be used for pausing the counting process of a timer IC during power failures, and also restart the process when mains is restored, ensuring a continuous functioning of the timer without errors. The idea was requested by Mr. Arun Dev. Technical […]
