Franklin,
Thanks that is very generous but I'm more of an all in one designer and manufacturer so I do have a profit from that (it was not always the case in the first few years but now it is fine).
I do not feel like Patreon and similar services apply to what I do as I no longer make youtube videos or offer any similar learning or entertainment services other than providing support for products that I sell.
If I were to just design open source hardware and software (not manufacture them) then Patreon or similar services will make total sense.
