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
- Ethernet cable(for internet connection)
- monitor

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.
