Have you tried some designs with the mechanical triggering automated (based on the book modules upward movement)? If so, what's your take on it?
I imagine that strain from pulling the handbrake is a bigger risk than strain from raising/lowering the module, given the neat counterbalancing. A challenge is to get a autotrigger to work reliably given that
1. different books differ in "height" (= thickness) and
2. the same book varies in "height" when you're scanning different parts of it.
Problem 1 seems easy to solve through a one time per book calibration of the trigger part. Problem 2 could be trickier. Maybe the platen could be made to move 1 cm upwards/downwards when pushed/not pushed by the manually lifted book module. That platen motion could be transferred to mechanical camera triggering. That could solve problem 2.

What's the story with this?

probably be a little more stable when using it upside down for paperbacks. Keeping it from racking.
