Comment by JKCalhoun

I took a deep dive for 12 months on how analog computers work(ed) and the result was a little kit and book that represent a kind of analog computer primer [1]. In short I took what I learned over the year and made something that would fast track others (you can probably go through the manual + kit in about two weeks and know as much as I do now).

I had originally wanted to get one of those Analog Things but was a little put off by the price (so of course I spent close to an order of magnitude more to develop my own analog computer).

(The ESP32 I added for the backend, to display the voltages/values [2], is, I think, the coolest thing I contributed to the hobbyist analog-computer niche.)
