Replying to myself to add…
This was all while installing this and that dependency and troubleshooting it. Docker was a complication I didn’t want to learn yet.
And then tinytinyrss moved to docker only which forced my hand. I can say installing Docker and Portainer (as someone who prefers a GUI more than command line) has made self hosting so much easier for me, and hugely reduces the need to think about dependencies.
I ordered one of these off Ali Express. An oscilloscope app showed it was about 40Hz vibration from the weight on the motor, far far from being ultrasonic. Got a refund, it ended up in the recycling.
