The digital sinewave oscillator is a device used for generating sinusoidal sinewave signals using digital logical signals. The oscillator circuit has two sections, which also have their own useful applications. […]
Square Wave Generator Circuit with External ON/OFF Control
In this post we discuss a simple yet extremely stable CMOS square wave generator circuit whose output can be controlled ON/OFF through an external high/low signal. In electronic digital circuits […]
Noise Generator Circuit
In this post we learn about a simple circuit which can be customized to generate a wide range of noise frequencies. Noise refers to unwanted electrical signals in a pretty […]
Simple Insect Repellent Circuit [Tested]
The theory of insect repellent circuit is quite complex though it is possible to give a rough outline of what happens. It seems that mosquitoes and other nasty insects only […]
Motor Boat Sound Generator Circuit
Imagine a motor boat running all around in your room. For this you neither need water nor a big bulky wooden frame with a heavy engine fixed to it, but […]
1 MHz Time Base Generator Circuit
For clock generators which are used in microcontrollers, the designs are mostly crystal based. You may say crystals have become cheaper over the years, yet they are compatively expensive ieven […]
