Sample Comments
That might be pushing the boundaries of "no moving parts".
This calls for a motorized solution!
Random question, why not 1 blade and a counterweight?
I dont trust that it’s a pure mechanical system
No rotary encoders on those things?
Less moving parts to wear out ?
Stepper motors and an active feedback loop most likely.
Wouldn't a slip ring help here?
How does he convert a variable speed hand motion to a constant speed rolling? Some spring mechanism?
Next step: Add a tiny motor inside the key switch for force feedback
