I was picky about the ones I feed to.. community ones I feed to are adsb.fi, adsb.lol, airplanes.live, plane.watch, opensky-network, and on the commercial side, flight radar 24 and fightaware, both give premium access for feeding, which is nice.
I know you can set up a self-hosted Signal server, but I'm not aware of any relay/proxy type apps
Interesting, never heard of this before... more powerful than a looking glass. Neat
Self-Hosting to help a community?
Recently, I've stumbled on more self-hosting projects that help out different communities/groups/non-profits. Examples:
- RIPE Atlas Probe
- Tor Snowflake (or relay)
- Archive Team Warrior
With a hardware investment:
- ADS-B Feeder (need SDR)
- Weather Underground (need weather station)
What else is out there along these lines?
I'm less interested in things like CryptoCurrency nodes or mining (including things like Helium), or very resource-heavy things like Folding@home.
