@p @mia @jeremiah @verita84 Equipment needed: Raspberry Pi, RTL-SDR, 1090 MHz antenna, band-pass filter (optional, useful in crowded areas)

Software: PiAware (Debian-based distro made by Flight-Aware), just flash it onto an SD card

Here's a tutorial on it: https://flightaware.com/adsb/piaware/build

If you contribute your Pi's tracking to their network, they give you a free "enterprise" account to view all flight data, but I'm under the impression that a lot of it is censored, and you can't get the historical stuff (which is what's VERY interesting) without $$$$-level access, so being part of their network doesn't have that much actual benefit.
