Rentals (not repairs), to be clear, but man were they heavy to ship. I did have a few rentals to bigger companies (Google, Samsung), sometimes it's easier for them to rent.

Yeah, most of them are random hacks. I don't mean to imply they were all intended to be businesses, though some were. More just meaning I have a lack of direction and haven't produced much of real value, despite thinking I was. After ten years, you realize the code and time spent starts to pile up.
