HP Archeves

[Martin Hepperle]

Interesting.

The "one weekend" project is probably more like a "one summer/winter" project. Very professional, but also complex and costly. More suited for a library (e.g. in developing countries) or an organization.

Another simpler "Buchscanner" (more suitable for building at home) was also published in the German Make Magazine. Maybe similar things appeared in the US issues of Make Magazine.

This simpler one was made from wood and uses a camera on a pendulum which swings to take pictures of both pages. You have to turn the pages by hand, though...which may be preferred for valuable books anyway.

For good quality all these projects use a glass plate (resp. two) to keep the pages flat for photographing. Camera resolution should yield between 300 and 600 dpi on the final page.
