Many people make electronics as a hobby. It's probably a fairly high-impact hobby compared to knitting or reading, but I'd credit the author for at least thinking of a use case for their little microcontroller board. I also imagine they soldered all of the PCBs they got, instead of buying five, populating two, and leaving both in a drawer after bring-up which is so normal now that PCBs are so cheap.
