It’s a good candidate since it sounds like there’s no precision mechanical components like there would be in a hard drive. Does anyone have ideas for how I’d go about this? Is there a barrier I’m not considering?
I know how to make basic semiconductors already, so that’s not an issue.
Edit: I’ve got an answer written down in the comments now. TL;DR you’d still need lithography to do it the OG way, because of the patterned magnetic material that directed bubbles around the medium, but material requirements are actually pretty flexible.
Basic semiconductors… like ICs?
When someone says basic semiconductor, my first thought would be a single diode or maybe a transistor, not an entire integrated circuit.
Really bad ones with visible-sized features, yes. I linked a YouTube channel elsewhere in here.
