So what is next on the agenda? The nice thing about your first subject is that as someone who has a bit of experience with KiCad, but a limited amount of formal training, it's nice to see some direction as to how to set projects up files-wise. So good for noobs and some experienced people alike.
IMO, the shorter length is welcome, though I'm not sure how YouTube prioritizes that sort of length versus the typical 10-minute+ clips. Maybe good for search and you can bank on getting people to subscribe (and hopefully notify)?
I guess the good and bad thing is that things change from year to year. So plenty of room for fresh content, but only so evergreen so to speak. Anyway, good luck!
