Hey! I am planning to build this: http://www.aaroncake.net/Circuits/fmtrans.asp
FM transmitter

I just wanted to know the Inductances of the coils because I might encounter errors winding them and I might want to 'resize'...

The Wattage of the TX...

If A CD/MP3/cellphone input would be possible(any additional parts to include?) and another output jack for speakers(dual output; 1 for speakers, 1 for transmitting to a distant listener)

I am an electronics student
very much fascinated by these wireless devices and transmissions and high voltages from an AA battery...
really inspires me!

This transmitter isn't suitable for sending high quality audio. First, it's mono. Second, the audio quality is poor and this hobbyist level circuit drifts a bit.

The inductor values are not critical. If you build according to the instructions, the circuit will work. You can bend the coils of the inductor to make fine adjustments.
