here it is
It's not much, but it's entirely off the shelf from hardware stores,
the main structure is made of two Mottez bicycle wall hooks, linked together by three regular 1 meter aluminium tubes, plus one across for rigidity,
held by a few wall mounts for pipes which fit oh-so-neatly in the hooks' holes using the supplied screw plugs.
The wall hook is shorter on one side, which makes it ideal to set up any length and angle of platten I might want.
It's resizable by sliding along the tubes and multiple holes can be drilled on the platten to allow an angle to be maintained while increasing the width.
It's very easily rocked backwards to allow for page turn, since it's rounded in the back, and when brought again forward it will rest on the book.
Two bicycle camera mounts are placed on the main structure and allow multi-directional easy positioning,
I picked up two Osram battery powered LED bars to test, and I know LEDs are not the best solution, however I was shooting for absolute portability.
This picture shows the L brackets which will attach to the platten. The screw is a bit too long since I hadn't bought a smaller one. I'll post specs on all parts and pieces on my next update.
For the platten I had another portability idea, and I'm aware of the problems involved. I'll be using two plexiglass sheets, joined by some very small hinges, painted white and secured by a strong adhesive tape. This will obviously be in the way of double page content, but a platten isn't exactly the most portable part of any scanner, and my main goal is to be able to travel and scan my books overseas so I won't need to have all of them shipped.
For the cover, the pipe mounts allow me to replace the screw, so I can pretty much buy a screw bar, cut to any height, mount it pointing up and work from there. Or just throw it over the whole thing as it is, the pipe's ends go over the end of the structure, so any fabric won't interefere, plus with LEDs there's no heating problem.
For the trigger, I'm still trying to find in my bookmarks a bicycle-brake trigger that I found online, but no luck so far...
