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.
If you decide to set up an SDR for ADS-B, you might want to consider setting up a WebSDR with something like OpenWebRX. This would let people listen to all the signals in the bandwidth that you set.
If you’re interested, receiverbook.de is a list of most WebSDRs.
