==DESCRIPTION==
Raspberry PI-based FM transmitter programmed to transmit FM signals streamed in the the UP-FM website using SOX(Sound exchange) application.
==SPECS==
* Input stream via ethernet: up-fm.org
* Low-power FM transmission: analog at 87.MHz
* Can amplify the FM signal(output) of the transmitter for covering longer distance.
==I. COMPONENTS ==

PROCEEDURES

A. Making a Simple Antenna:

  • Since you don't have an ideal antenna,you will use a solid wire (no.22,) as a substitute antenna.Cut a solid wire about 32 cm(centimeters) and stripe one end at least 1 cm. Also cut the GPIO cable wire near the socket and leave at least 1 cm wire on it.Stripe the wire near the GPIO socket. Combine both ends of the solid wire and GPIO socket using lead and soldering iron.Wrap the soldered wire ang GPIO with the tape so that it will not stumble as shown below.


B. Programming the PIfm:

  • You will now program the PIfm in Raspberry PI.First you must have an SD card with Raspbian "wheezy" OS.
