Simplest FM radio Transmitter with the YX8115 transitor

The YX8115 Transistor is a driver IC developed for flashlight illumination. Mainly used as an oscillator and driver transistor for voltage boosting. But recently I found out that it can also be used to build a Transmitter...

Components required:
1: YX8115 Transistor

2. Two 3.7 lithium cells in series: 7.4v

3. Any unpolarized capacitor.

4. Inductor / coil: any low impedance coil will do... 12v and 24v Relay coils also work better than what I used in the video... A 12v transformer will also work too with the primary side being the audio input and the secondary side acting as the inductor In the circuit... Air coils are the best because with air coils the transmitter can transmit effectively over a fairly long distance..


Feel free use the circuit diagram and even make and tweak yours to make it more efficient and effective..... Don't forget to subscribe...
