I saw this (episode 1) and episode 2 a few days ago. At the end of episode 1 I was left pretty skeptical that he'd ever get this contraption working well, but the solution he shows in episode 2 completely flipped my expectations and looks aesthetically incredible.

(He makes his own very thin brass coil springs to run the cables through.)

Fyi, episode 3 is out as of ~3 hrs ago:
