2. FM Radio Transmitter (Version A)
To build this simple radio transmitter, you will need to gather the parts such as a 9V battery, a clip, wires, a prototype board, a trimmer capacitor, a resistor, an audio plug, etc. From tools, you’ll need a pocket knife, a pair of mini-pliers and cutting pliers, a lighter, a candle wax, a 5mm bolt, and a ruler. First, you need to form a 5-turn coil and stretch it to about 1cm. Solder the leads onto the board and then insert the other components. Take a look at the video to see how it’s done.
And now, let’s see the number one on our list of easiest simple FM transmitters to make at home.
