How to make FM transmitter

A short range FM transmitter is a low-power FM radio transmitter that broadcasts a signal from a portable audio device (such as an MP3 player) to a standard FM radio. Most of these transmitters plug into the device’s headphone jack and then broadcast the signal over an FM broadcast band frequency, so that it can be picked up by any nearby radio. This allows portable audio devices to make use of the louder or better sound quality of a home audio system or car stereo without requiring a wired connection. Being low-powered, most transmitters typically have a short range of 100–300 feet (30–100 meters), depending on the quality of the receiver, obstructions and elevation. Typically they broadcast on any FM frequency from 87.5 to 108.0 MHz in most of the world . In this project we design the circuit in such a way that ,the circuit will collect the input through aux cable and broadcast with in FM frequency range. The broadcasted output can be collected with a FM radio. Now I am going to instruct how to make a FM Transmitter with less number of components.”
