Thanks, I have read a lot of human-written text (and actual books from the day) in addition to the LLM feedback. Again though, had I ignored LLMs altogether I would have barely progressed in the past two months. I think. They seem to act as an "idea board" of sorts—sends me out then looking for others to validate (or not) what they're spouting.

"Schottky diodes to protect op-amp inputs…" Not op-amp inputs, ADC inputs (which may well come from an op-amp output though—I am playing with analog computing after all).
