I built a self-build ATTiny85-based dev board[1] with a bunch of tutorial projects[2] designed for time poor people, most recently an EMF detector[3] for Halloween. Unless you include the LPC810, it's pretty much impossible to do anything similar on ARM. A lot of people seem to think everything needs at least a Cortex-M0 but in reality, an AVR or PIC is more than enough for most projects. There's also a lot more accessibility with through hole projects. Sure it's larger and more expensive than buying a pre-built board, but for most beginners through hole is way more accessible than surface mount.
