In this post I have explained a single phase variable frequency drive circuit or a VFD circuit for controlling AC motor sped without affecting their operational specifications. What is a VFD Motors and other similar inductive loads specifically do not “like” operating with frequencies that might be not within their manufacturing specs, and tend to […]

2 Simple Voltage to Frequency Converter Circuits Explained
A voltage to frequency converter circuit converts a proportionately varying input voltage int a proportionately varying output frequency. The first design is using the IC VFC32 which is an advanced voltage to frequency converter device from BURR-BROWN specifically designed to produce an extremely proportional frequency response to the fed input voltage for a given voltage […]
2 Simple Light to Frequency Converter Circuits for Transforming Light into Pulses
In this article we are going to see what is a light to frequency converter circuit, how it works, how to use it in a project, and its specifications. No matter which category you belong to, professional, hobbyist, engineer or student, modular components always reduce half of our headache while designing circuits. They eliminate the […]
1 Hz to 1 MHz Frequency Reference Generator Circuit Diagram
This circuit is an universal frequency generator which you can use in numerous frequency and time period testing applications. It is primarily well suited for a gate pulse generator in frequency counters. The circuit is capable of generating an entire range of reference frequencies such as 1 Hz, 5 Hz, 10 Hz, 50 Hz, 100 […]
Extremely Low Frequency (ELF) Radiation Monitor Circuit
ELF stands for Extremely Low Frequency, which is an electromagnetic radiation generated by most of out household electrical equipment. Regarding the effect and severity of ELF fields on human health, debate remains heated. However, I believe there is enough data for us enthusiasts to adopt a conservative stance on the level of exposure we must […]
3 Simple Frequency Counter Circuits Discussed
In this post we are going learn how to construct 3 different frequency counter circuits using ordinary components and ICs which will showcase the measured frequency on 7 segment displays. The first circuit which uses 4026 ICs can measure frequencies up to 1 MHz and the circuit is user calibrated. We will Learn About: Block […]
