Short Rage Wireless Music Transmitter

Now , i am with a short range wireless FM transmitter which can powered through USB. It can take audio signals and transmit it over a short . It's maximum rage is around 100- 150 meters.you can easily listen it over a radio . it's very cheap and easy to build.

All you need are some common electronic components.
You can buy them at Radio Shack!

1. Transistor BC 548 OR 2N2219a.

2.Capacitors : 1n , 1n , 10p , 10p variable , 1uF electrolytic.

3. Resistors : 2k7 or 2.7 k , 1k , 10k , 10 variable.

4. Inductor : you can make by yourself . 7 turns on 3mm or  6 turns3mm.

5. Battery : 9 volt .

6.  PCB you have to make one or use breadboard.

7. Antenna 10 cm long!

8. Nothing else

Here is the simple circuit diagram!

Here is the PCB layout.
In the next PCB  the red ones are capacitors , green ones are resistors , brown one is variable resistor , white one is transistor , yellow one is inductor and other holes are for power and input and antenna.
