Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

OpenSource Self-made Hardware Security Key?
FWIW, there is u2f-zero — a DIY U2F token.

Please help
keep and eye out for this issue: https://github.com/greatscottgadgets/hackrf/issues/668

I have seen comments and github issues about HackRFs being damaged by high power transmissions. I live 500-600 meters from an airport, should I be worried?
I have read about this issue on github (have been some reddit posts over the years as well), originally in #541 which has now culminated in an ongoing investigation #974.

Which SDR should I rather buy?
However, unlike your sensitivity issues, i dont get any birdies. i have a TCXO though. (https://github.com/greatscottgadgets/hackrf/issues/216). it seems its related to clock drift calibration without one. However this is something most SDR's suffer from, as a cost saving measure. Most RTL_SDR's suffer from this as well ("rtl sdr blog v3" comes with a stable TCXO, resolving the issue.).

External LNA and broken TX
I assume this is the case since I found a GitHub issue talking about blown TX: https://github.com/greatscottgadgets/hackrf/issues/1051 And I followed the recommendation of using hackrf_transfer -c with both -a 0 and -a 1. With a separate RTL SDR tuned to the output frequency I can see a very low power CW signal with -a 0. With -a 1 there is no output. This seems to match the results in the issue.

Samsung phone
If you're talking about building attachments to work with a phone, you're almost all the way there to a standalone device anyway. You might want to look into HackRF and pwnagotchi for inspiration.

Is there any software for rtl sdr that can read signal and emulate it, for windows or Linux? PLEASE HELP!
If you get a HackRF there's a utility called hackrf_transfer which can record a block of spectrum and then play it back.
