New Synth Knob Multiplexer - 64 Analogs in one! Part 3

So you know I'm exactly halfway in the middle of my 64-in-1 analog knob multiplexer project, right? To keep it exciting, I did a "Soldering Challenge." Enjoy the time-lapse video!

My bigger goal is to demonstrate all 64 knobs at once, but that's so many circuit boards... and I just got back from a sublimely relaxing vacation... so I decided to challenge myself to build them all in one hour. If I succeeded, I motivated myself with a relaxing swim at Walden Pond.
