I make open source hardware password managers called @Signet. Oh, and I maintain Ansible roles/playbooks to make self-hosting things easier. I also grow and preserve my own food, but that's not something I sell. That's just for me. No interest in selling any of that. I'll share my experience though. I guess I do woodshop projects from time to time too. Again, those are just for me, but I'm willing to share what I learn.
