Using PiFM to transmit audio on any frequency up to 250 MHz @Raspberry_Pi #piday #raspberrypi

Pifm30

In this tutorial, Tom Herbison demonstrates how to use a pi as an fm radio transmitter. Please be sure to read through the guide carefully as there are numerous warnings on what not to do during the build:

The first “hack” which allowed experimenters to use the Raspberry Pi’s clock pin (GPIO 4) to transmit audio directly from the Raspberry Pi came from the Imperial College Robotics Society . Their “PiFM” module has since been modified and improved and is now capable of transmitting in 16 Bit Stereo on any frequency from about 1 MHz up to 250 MHz.

It sounds too good to be true…. so I decided to try it out for myself!

WARNING – DO NOT connect your Raspberry Pi’s clock pin (GPIO 4) to any kind of antenna (even a short length of wire) when performing any of these tests!

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
