Editor’s note: The Raspberry Pi’s broadcast frequency can range between 1Mhz and 250Mhz, which may interfere with government bands. We advise that you limit your transmissions to the standard FM band of 87.5MHz–108.0MHz (see Step 5) and always choose a frequency that’s not already in use, to avoid interference with licensed broadcasters.
What better way to celebrate the launch of the tiny, $5 Raspberry Pi Zero than to build a project. The Raspberry Pi Pirate Radio is one of our favorite builds here at Make:, so it was an obvious pick to port to the new board. In case you missed our first crack at Pirate Radio, try it building it while you wait for your Pi Zero to arrive. PiFM was originally written by Oliver Mattos and Oskar Weigl, and revised by Ryan Grassel.
Pirate Radio is an extremely simple build: Cut and solder one wire to the Pi. The software installation and configuration doesn’t take too long either. Here is how we shrunk down the Pirate Radio into into a Pirate Radio throwie.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
