One of the coolest things I ever built was a "bouncing ball simulator" [0] for my analog electronics class in college. I'be built a lot of stuff with embedded processors throughout my life, but that one project changed how I viewed electronics. Assembling a bunch of op-amps, FETs, and passives and having it output a physical representation of a ball being dropped and bouncing off of the ground was just magic to me. I don't do much with analog these days, but when I get into a project that needs it, I still draw from the confidence that project instilled in me. Before then I struggled to see analog circuits as tools to solve problems, but for some reason after building the simulator, it just clicked and I saw the possibilities. I wish I had soldered the thing together. I still remember the day I ripped up my 6 breadboards for the next lab...we built a Theremin though, so at least that was cool.
