One transistor FM receiver

One transistor FM receiver

In this exciting project, not only will you have a very unique one transistor FM recevier, but also be in-store for making home-made air-core coils and a home-made fixed capacitor. And even more than that, when you finish ‘your’ project, your journey has just started. With your now-working FM receiver, you can start experimenting with other wonderful things.There are 12 component count on this project. One transistor FM receiver

Using 555 as FM transmitter Circuit Diagram

The integrated circuit 555 has no limits, this FM transmitter circuit, the IC 555 is designed as an stable multivibrator as usual. But the tension control pin is used to connect a piezoelectric element instead of the capacitor disk. The piezoelectric element generates a voltage and the output pin is connected to an antenna wire 30 inches for the transmission of signals.Just tap the piezo element and you can hear the sound on an FM radio station. The range is very short.
