In the following content I have explained two simple 12V, 1 Amp switch mode power supply (SMPS) circuit using the very reliable VIPerXX IC from ST microelectronics. With the advent of modern ICs and circuits, the age old iron transformer type of power supply are surely becoming obsolete. Today power supplies are much compact, smaller […]

Morse Code Practice Oscillator Circuits
In this article we will explore 3 different Morse code practice oscillator circuits, for generating exact replication of Morse code signals in the form of dots and dashes. Contributed By: Anil Patil What is Morse Code Morse code is a legacy method of message encoding that uses rhythm and impulses to transmit telegraphic communication. Morse […]
Simple IC Tester Circuit [Test Digital and Analogue ICs]
The IC Tester is simple to use. You don’t have any switches to configure or lengthy test processes to complete. The universal IC Tester is a static tester, which means this does not dynamically test the IC’s operation. All ICs with up to 20 pins can be tested by this unit. ICs with more than […]
Signal Injector Circuits for Quick Troubleshooting of all Audio Equipment
This simple signal injector circuits I have explained below can be accurately used for troubleshooting and alignment applications of all kinds of audio and high frequency equipment. 1) Using a Single IC 7400 One of the extremely handy devices for repairing audio and high frequency instruments is without question a equipment that will give you […]
Understanding Crystal Oscillator Circuits
Crystal oscillators are electronics devices that produce stable, accurate, and repeated signals that are widely employed in a wide range of electronic applications. Because of their great stability, precision, and low noise, they have become a crucial component in many electronic circuits. In this post, we will look at how crystal oscillators function, as well […]
Field Strength Meter Circuit
A field strength meter is an electronic device which is used for detecting and measuring the RF radiation generated from any RF transmitter circuit. As we all know that transmitter circuits invariably use an inductor/capacitor based LC resonating circuit, also called the tank circuit, which oscillates at a specified resonating frequency to transmit the frequency […]
