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. Combine both ends of the solid wire and GPIO socket using lead and soldering iron.
