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!
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.
