Monitor Airplane Traffic with a Raspberry Pi
Commercial flight trackers encourage enthusiasts to feed them data, then take money from operators to hide that data. If you want everyone to have access to the data, consider feeding a network that doesn't censor or block anything, like ADS-B Exchange (https://www.adsbexchange.com/).A project like Dictator Alert (https://dictatoralert.org/) uses ADS-B Exchange because the authoritarian regimes they're tracking can just pay a commercial site to hide their aircraft—they don't like being tracked.My Advisory Circular bots (https://skycircl.es/bots/), which tweet in real time whenever they detect police, FBI, military, news or fire aircraft circling, and my "What's Overhead?" Siri shortcut (https://twitter.com/lemonodor/status/1238149529469202433) use ADS-B Exchange because a lot of the most interesting aircraft are the ones that are blocked on commercial trackers.
