Build a simple FM transmitter with a raspberry pi and a piece of wire for the antenna

1) Get a raspberry pi

2) get whatever Linux on it

3) install sox to read internet streams : $ sudo apt-get install sox libsox-fmt-all

4) wget http://www.icrobotics.co.uk/wiki/images/c/c3/Pifm.tar.gz tar -xvf Pifm.tar.gz

5) start the bbc on 103.3FM

$ sox -v .9 -t mp3 http://bbcwssc.ic.llnwd.net/stream/bbcwssc_mp1_ws-eieuk -t wav --input-buffer 80000 -r 22050 -c 1 - | sudo /home/pi/pifm/pifm - 103.3

6) improve the range from 10cm to 100m by plugging a piece of wire in the 4th GPIO pin. I took an old headset, cut at both ends, plugged. no soldering needed, google to find which GPIO is the 4th one.

7) replace the bbc stream with France Info or France Inter or whatever stream : France Bleu Breizh, Tendance Ouest Rouen, Kiss FM dance or whatever obscure campus radio that streams on internet. Yay.
