Building my DIY book scanner

DIY Book Scanner

Hungarian version of this article is available on djvu.hu

To explain this book scanner idea in a few words, compared to traditional flatbed scanners or special flatbed book scanners:

  • 90 degree holder plate for the book
  • no need to push the book
  • no need to disassemble the book
  • built from cheap leftover material
  • scanning with a compact photo camera
  • no wait for a flatbed scanner to move across a page slooooooooowly

There is an excellent community for building home made book scanners. By following the guides on diybookscanner.org it's easy to build your own scanner, that can scan a 300 pages book in 30 minutes. After 1.5 hours postprocessing work (in ScanTailor) you'll have very good black & white TIF images, that are straight, cleaned from noise, well readable. (No OCR or single-file conversion is included in this time frame.)

Have you ever had the problem that your camera's date was misset or reset, so all your EXIF and file dates were broken?

In this case you need to adjust the date in several images and preferably alter the file date accordingly. This is much easier than you thought, two simple commands using Linux tool exiv2.

The www.openstreetmap.hu domain was occupied by an empty HTML file for years. Recently I discovered it is free, so registered it immediately. Let's see if someone will complain.

Update: The old owner of the domain is happy with the new site. :-)

With help of an OSM-JS professional, we got the new site up & running in a few days  - thank you mate!
