Make this Car Interior Light Fader Circuit
In this post I have explained a simple circuit which can be used for producing a slow fading light effect each time it’s switched OFF. The application can be typically used in car interior lights. Designed by: Abu-Hafss The Circuit Concept Most of the modern cars are equipped with circuitry which switches on the Car’s […]
Simple Cellphone Jammer Circuit
This is a RF jammer designed for the U.S. 800 MHz cellular phone band (870-895 MHz). This works by generating an overwhelming sweeping RF carrier on the cell phone handset’s operating frequency range. Circuit Operation An Exar XR2206 Multi-purpose Generator is going to function as the triangle wave generator for supplying the sweep part of […]
Light Activated Water Level Controller Circuit
The light activated water level controller circuit explained here has the advantage of being corrosion free and much reliable than the traditional moisture sensor type of water sensors. Circuit Operation One slight downside of this LDR based sensor is that the tank interior always needs to be illuminated by some kind of light source such […]
Infrared Remote Control Safe Lock Circuit
A simple, cheap yet highly effective infrared remote control safe lock circuit can be studied in the following post. Using IC LM567 The LM567 IC is one of my favorites simply because it’s too versatile, and becomes applicable in most of the crucial circuit concepts through hassle free configurations. One such crucial yet simple IR […]
How to Measure Gain (β) of a BJT
In this post we’ll study a simple opamp circuit design which can be applied for measuring the beta or the forward current gain of a particular BJT in question. What is beta (β) The beta (β) is the forward current gain that every BJT inherently possesses. It determines the efficiency of the particular device in terms […]
