In this project, we’re building a Single Chip FM Radio. The heart of this circuit is a digital IC – TDA7000. The design involves proper use of inductors and capacitors with correct values. Since the IC is dedicated to build radio circuits, this circuit is very much reliable to an extent. Description. Here is a […]
In this project circuit, we’re building a Direct Coupled Radio Circuit using an inductor and 3 transistors mainly. This is a very basic, low cost, hobby purpose circuit – just for the learning purpose of “direct coupling” method. If you’re looking for a good radio circuit, you’d be better off with our FM Radio Circuits
Metal Detector Circuit I always wanted to make a metal detector seeing how cool it was in all Hollywood, Bollywood movies. One thing I realised is; things aren’t as difficult as you think it is. After all, I found that a metal detector is really simple and easy to make. So in this post, I
Simple Radio Circuit Op-amp is the short form for Operation Amplifier. It is a device used to amplify voltage, and is very popular due to its high gain amplification. It can often amplify voltage to hundred times of what is input. This project is aimed at making a simple radio circuit using an opamp. Description
Radio Collar Transmitter Radio collars or tracking collars are tracking devices used to study animal migration patterns, they are also used to keep tab of endangered species. In India, radio collars are commonly used on tigers to keep track of them. Obviously, a radio collar has a strap which is worn around the neck of the
