Oh, I'm surprised I didn't update that I did get the raspberry pi and running Raspbian on it rn. Haven't done a lot with it, though I also put RetroPie on it, which is a multi-game emulator, which worked fine (except kinda a pain to map controllers).
I will look into the Arduino and other single-board computers. Been checking out the various "Projects" docs that have some neat ideas for the future.
...In the meantime, now I am looking to dual-boot my laptop that I got. It's not really related to ARMs or anything, but I can still work on making it cute.
