Temperature Controlled Relay Switch Circuit
In this article I have explained a simple temperature controlled relay circuit which can be switched ON/OFF depending on the temperature on its temperature sensor. Meaning, when the temperature on its temperature sensor rises above a set threshold point, the relay switches ON, and when the temperature drops below the threshold, the relay switches OFF. […]
Electronic Cricket Sound Generator Circuit
In this post I have explained how to build a simple cricket chirping sound generator circuit using a single IC 4093 and a few other passive components. An electronic cricket sound generator is a device which generates a sound exactly similar to a real cricket insect. This is done using a set of oscillators configured […]
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 […]
Circuit Projects for Beginners and School Students
In this article I have explained how to build small electronic circuit projects suitable for beginners, young hobbyists, school students, who are new to electronics and are at the initial learning stage. Which Circuit Projects are Suitable for the Beginners? Warning: In this article there are a few circuits which are not isolated from AC […]
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 […]
