Gina Häußge is the only one making reasonable money on Patron for a software project, last I checked. I exchanged several emails with her about this very topic. Despite her success in fund raising, even she was concerned about the long-term viability of this sort of funding.
I also am the author of an active Open-Source project. I accept donations but they have never amounted to much.
