UP-FM Transmitter

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

a. For the PIfm:

• Raspberry Pi (model B)

• Solid wire (no. 22)

• 5 Volts,2 Amp. Power Brick

• SD card(at least 4 GB) with Raspbian "wheezy" O.S. on it

• GPIO wire

• USB micro

b.For programming:

• VGG to HDMI cable

• USB mouse

• USB keyboard

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.
