Somehow, i ended up being a part-time prof at the Estonian Arts Academy, teaching something called "applied electronics for sound and music" to people. Since the people are mostly non-technical, i tried making the course very beginner- and not-a-nerd-friendly. During the course, we build simplish stuff in form of tiny barebones modules, that later can be reused in projects. Below is a table of useful files, mostly aimed at the course students, but other people also can download these and try to squeeze out the most out of it.
