PiNumberStation is a python/bash coded front end that takes string messages and turns them into basic speech (preferably NATO phonetic alphabet or Combine VO) – this message is then passed over FM Radio transmission via a small antenna connected to GPIO pin 4. The hard part (modulating the sound and sending it to the antenna) is actually done by the back-end PiFM based C program.
The end result is a basic and very small FM Number Station that with adequate tweaking has the potential to be very powerful.
Legal Notice: The operation of an FM Transmitter (over a certain energy level) is in almost all countries and local jurisdictions illegal. Check the laws of your area before operating such a device.
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.
