Wanted to be able to send music to speakers outside the house say for a barbecue or whatever. Could use Blue tooth among other things, but I wanted something more secure and easier to generally implement. PiFM seemed to be an answer . With a RPi you can send an old fashion radio signal to a radio and the radio will play what is sent it. All you need is an up to date Raspian install on a Raspberry Pi with internet access. I used the original  Raspberry pi for this project. I will probably set one up with the RPi zero. (Note: check you local laws to see if this is allowed.) Also you need to have experience using you RPi remotely. Antenna needs to be at least 7-14 inches long. You need to log into your Rpi command line. All this can be done easily. First thing is to get some software from the software repo for doing software development. Don't worry it will not hurt too bad. Update the system: $ sudo apt-get update $ sudo apt-get upgrade -y $ sudo apt-get dist-update -y...

Try at your own risk. Your system could be damaged. Plug goes into a sound card output. Of course, you will need an AM capable radio to receive the transmissions. Dial needs to be set at or near 100x10khz. There was several strong competing stations where we tested this project.
