My goal was to be able to get these in a classroom at every seat This is really amazing and you are to be commended. And you've clearly thought hard about what can make that successful. There's just no replacement for every student having their own setup to experiment with. My first exposure to o-scopes, the whole class was basically sharing one giant Tek 7k series scope, one of the best of the time (with commiserate cost), and while I did learn the basics, it wasn't till I had my own much, much less feature filled scope did I learn it well enough to be useful. N.B.: Since you're new here, I'll just warn you that it's SoP around here that any time anyone posts an "I built this", the comments will be filled with nitpicks about trivial issues presented as massive errors, people telling you how much better they would have done it if they ever got around to doing it and how they got something cheaper on alibaba so why bother. And, of course, you should have written it in Rust. Just ignore that stuff.
