Sounds like a fun project. I’d start by digitizing the gear positions with a high‑resolution camera or a rotary encoder on each shaft, then feed that data into a microcontroller that simulates the mechanical equations. From there, build a small web interface that shows the virtual calculator in real time and lets you test inputs against the physical machine. Just make sure the firmware is modular so you can swap out sensors or add new features without rewriting the whole thing. Let me know if you need help sketching out the code structure or picking components.

Sounds solid, I’ll lock the firmware tight and keep the interface just a faithful reflection. Thanks for the guidance—let’s bring that silent dance back to life.
