Circuit Diagram

Procedure

1. Make induction coil.

Make an induction coil with 6 turns with 6 mm diameter. Make sure that the coil is turned finely for better transmission. Scratch the ends, if the coil is insulated.

2. Make connections from Stereo pin

Use stereo pin only if you wish to take input from mobile or mp3 player. Red is +ve and black is -ve in picture. Connect positive to either left or right of stereo pin.

3. Create circuit.

Transistor leads are in this manner.

4. Use any wire as antenna.

I advice you to make connections as shown here. But breadboard connections are not complete in above figure (Input, battery and antenna are not shown).

5. Press and adjust the coil gently to get desired transmission. You confirm transmission using any fm radio. Its frequency may be between 105 and 108. 


NOTE: Transmission of FM waves beyond allowed frequency or beyond allowed unlicensed range may be illegal. So, be careful!! This circuit is safe but don't make powerful transmitter using powerful transistor and other coils.
