Introduction: Live Radio Raspberry FM Transmitter

By
About: My name is Tijn Vos. I am 17 years old, live in the Netherlands, have my own workstation. I like to work with wood, metal and electronics. I like to build stuff to keep my mind going. Follow me …

This is one of my latest projects that I've been working on, it's a Retro Raspberry Pi radio transmitter. With this invention you are able to simply enter a FM frequency and talk on your favourite channel in a range of about 200 metres. It has a build in 9 volt battery with a 5vdc regulator. I finished it with a nice mahony-brass case. Hope you like it.

Step 1: Installing PiFm and Special Codes

PiFM was originally created by Oliver Mattos and Oskar Weigl, and revised by Ryan Grassel. After the Pifm install I installed a Tft touch screen. Maybe in some future project I will install a touchscreen option like some application menu. I also have written some codes and build a usb microphone. To finish it of I soldered pin 4 to the brass case to function as antenna.

    Hi,

    Where can I get details of the microphone construction/connection and the extra code?

    This is great! I have played with pifm before, and it sure works! This project is better though... I can transmit live! I'll give this a try on ham radio band and see if any of operators near me can hear...

    For people who doesn't know what ham radio is, it's a licensed radio service (sort of like an FRS or GMRS)

    Thanks, would be awesome to increase the range. No one ever did that with a raspberry how far I know. The best part is I can just plug a jackplug cable in the USB hub and connect it to my phone forlive music streaming.
