Yours is amazing work, and certainly a higher degree of fidelity than I was able to achieve with AI assistance. The initial motivation behind this was largely driven by curiosity around the rotor motion (the ratchet and pawl assembly), and then into how the wiring actually works. For my brain, I needed to press the keys a hundred times and watch the current flow before it started making sense.

I'm curious about how you worked out the inner dimensions and part placements so accurately. Thank you for providing this marvelous free resource!
