This talk will teach you how to receive and make sense of messages from aircraft in real time using an ADS-B receiver / software defined radio. You'll see how to decode the messages, store them in a CrateDB database, and make sense of them. Finally, I'll demonstrate a system that alerts you when specific types of aircraft are passing by so you can run outside and see that 747 go past. I'll be working with Node.js code that runs on a Raspberry Pi, a Radarbox flight stick and a flip dot sign that I bought from a bus dismantling company!
