In my opinion this course https://tc.gts3.org/cs3210/2020/spring/lab.html, is the best OS course ever, perhaps even the best computer science course ever. Thru the labs you build a bare metal OS for raspberry pi using Rust. I went thru it on my own and was able to complete most of it. Running your OS on real hardware is way more satisfying than doing it on emulator.
