>Oh shit that's actually really good. Is there a name for that circuit?

I picked it up from an old-timer who just treated it as the default way to do compact triangle wave generation, I don't really know if there's a name. there's a couple iterations of it, but you're right, they really don't come up much when you're looking for things on google.

Pic related is literally the textbook op-amp VCO, and a variation of what we've been talking about. this is given on page 240 of H&H, under a section titled "Voltage-controlled-oscillator"

it's a small section, but this is the general idea behind most VCO's. H&H actually talks about it being borrowed for the book from some manufacturer datasheets - there's a bit of a hint there. datasheets will often teach you more than a textbook.
