The project is about the size of a standard AA battery which aims to build a single transistor FM transmitter. Having a power supply of 1.5V cell is the main advantage of this circuit. The battery is ...

Would-be spooks and spies, take note: this one-transistor FM transmitter is a circuit you might want to keep in mind for your bugging needs. True, field agents aren’t likely to need to build their own ...

The chances are that many of you will have made an FM “bug” style transmitter, a simple one-transistor oscillator usually driven by a small electret microphone. It’s also relatively straightforward to ...

One of the easiest, simplest ways to make an FM transmitter is to buy this kit from BuildCircuit. It’s amateur friendly, so anyone should be able to use it. What you need for assembling this ...

Here is a wireless FM Transmitter which uses RF communication to transmit the medium or low power FM signal with the maximum transmission range of around 2 km. Here is a wireless FM Transmitter which ...
