2 Simple RF Detector Circuits Explored
In this article I have explained a couple of very easy to build RF detector circuits, which can be used to sense or detect or sorts of Rf electrical noise that may be floating in the surrounding atmosphere. What is RF RF stands for radio frequency, which is a kind of electrical interference transmitted in […]
Transistor Monostable Circuits with Applications
In this post I have explained how to build a few simple monostable circuits using only transistors, and also learn how to make practical application circuits with them. If you search for transistor monostable circuit online, you will find that one typical circuit has been discussed in all the online articles. This circuit looks a […]
Clipper and Clamper Circuits Explained
In this post I am going to explain clipper and clamper circuits. The clipper and clamper are called wave shaping circuits because they convert the incoming signal wave to another kind of useful wave. They are used widely in power supplies, filter circuits, RF transmitters / receivers, voltage suppressors, audio amplifiers and the list goes […]
How to Design Simple LED Driver Circuits
In this article I have explained how to design your own customized, simple LED driver circuits at home. We will learn how to calculate specific LED configurations for applying the LEDs with appropriate LED driver power supplies. In these driver power supplies I have explained two concepts one by using SMPS boards and the other […]
Simple Temperature Indicator Circuits using Thermistors
A thermometer may be required for the precise measurement of temperatures. However, in many cases, an absolute value isn’t required and a relative estimate is sufficient. For example, the consumer may be alerted to the fact that an electric drill or vacuum cleaner is becoming hot, through a basic LED illumination, or through changing color […]
