Another ADHD person here and I think my vision is almost the same as the creators. My goal is to build a fully self-hosted risc-v computer from scratch.
It now took me 3 iterations and 3 years to get a somehow working risc-v CPU written in VHDL, that I am mostly satisfied with. It's a crazy hard struggle (finally pipelined though!). Everything breaks, I constantly get headaches and almost want to quit, but somehow I can keep on pushing this project. It helps me a lot.
Almost nothing works, things break all the time, it doesn't even look cool. But somehow it's satisfying that I can type words with a PS/2 keyboard on a VGA screen getting processed by my own RISC-V CPU (running Rust btw lol. I ditched that by now though, the struggle was too big). See here: https://i.imgur.com/PtKeAYt.mp4
I have no idea how far I can make it, maybe not fully self-hosted, but a small OS should be doable. I have interrupts and timers working, so I should have everything I need.
The downside is, I am way worse than OP and have no documentation at all. I should do that, but that's where the motivation is missing.
Edit: I type so slow in the video because I did poll the scancodes (too slow) and had to think which characters not to press, because i dont accept all yet and was scared that it breaks
