Introduction

I’m not very familiar with the aviation jargon (see FAA’s ADS-B FAQ), but ADS-B is a next-gen system where aircraft are equipped with transponders that periodically broadcast their own positions and receive the reports from both other aircraft (direct air-to-air) as well as air-traffic control (ATC) ground transmitters.

There are two separate ADS-B radio bands: the commercial aviation (CA) is at 1090 MHz while the general aviation (GA) is at 978 MHz. If I can be permitted a gross generalization—the former corresponds to big commercial jets and the latter to small private aircraft.

Because ADS-B is designed to democratize airspace situational awareness (in contrast to the older setup, like from films, where a central air-traffic controller is coordinating all these aircraft that can’t see each other), we can buy cheap RF receivers to pick up and decode the messages being broadcast by aircraft and ground towers to get our own picture of the

What?

A one-liner that pulls an AAC stream, pipes it into ffmpeg which transcodes it to mp3, then pipes it into ezstream with your settings (in the xml file) which streams it your radio.

Dependencies

sudo apt-get install ficy ffmpeg ezstream

Raspberry Pi Zero OTG Mode

Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).

The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int
