Archivar - wooden scanner based on Archivist

Built a scanner? Started to build a scanner? Record your progress here. Doesn't need to be a whole scanner - triggers and other parts are fine. Commercial scanners are fine too.

Archivar - wooden scanner based on Archivist

Post by blauer » 05 Oct 2017, 11:35

Hei!

My Name is David. I originally started building Bookscanners around 2 years ago, when Daniel retired from the forum. Since then I wanted to start a Business scanning Books and Building Bookscanners for others. Stuff got in the way, and I wasn't able to fulfill my dreams. Until some months ago:

We've (Me, My Wife and a friend) started again building Scanners for Copyshops and Archives nearby for some months now. We developed our own design upon Daniel's wooden Archivist.
We founded a company called Archivar Bookscanning e.U. and we are currently working on our webpage where we will sell bookscanners and bookscanner parts and have information on bookscanning in german. Scanners will ship as DIY Kits, in Austria we plan on offering maintenance and support as well.
On this page we will also have the design files of our scanner available for download free of charge. (With metric measurements, for all the europeans out here)

I want to share some design details with you:
Some goals were to
  • further simplify the connectors,
  • make a scanner that we can sell legally in europe (laws are crazy here)
  • Seamlessly integrate the electronics
(not finished yet)
  • Have a more easily adjustable weight support system
Wooden Scanner, Controlled via PiScan, The Parts are Lasercut out of 18mm Plywood:
Its main specs are the same as the Archivists
Image

Light module:
230V Lamps, aluminium housing, Easily Changeable
Image

Housing of the light module is now also made from plywood (4mm laser cut) the parts connect via rubber-rings:
Image

Screws now use, screw-in threads which are screwed into the wood, for assembly you only use m8 screws (no different screws anymore, just one type of m8 screw)
Image

Screen is integrated into the bottom of the scanner:
Image

For the weight support we use spring loaded tool balancers, which are perfekt for bookscanners :) the support can be finely adjusted to the book weight (actually not now, the fully tensioned balancers won't lift the cradle, we will add gas springs as well to compensate for the cradle weight)
But its working already like a charm when putting some weight on the handle as well:
I don't know whether someone had the idea of using these before, but I can see them integrated in many design for different purposes and they are cheap (about 10$)
Image

Power distribution and main switch is now integrated:
Image

And we added quick release plates for the cameras for ease, and to take them of quickly, for nighttime if the scanner stands in a public place for example
Image
Image

We kept using simple items, almost everything is available through amazon. Everything else is either 3D printed or laser cut.
The Scanner is called "Archivar" (which is German for Archivist)
Plans will be available on our website soon!

David

Congratulations on your design and the release of your scanners!

I've never heard of tool balancers before - they look like the perfect solution to the weight issue. Like you said, I can see them applied to many different things.

What's your web address?

Nice O-Ring fastener idea. Good find on the cheap tool balancers. I paid three times as much for the one on my lastest scanner.

I am very interested in Archivar scanner! I tried to find a carpenter who would make the plywood parts for me, but I have not found in Finland. And it seems that Lithuania is no longer doing the Archivist ... It's great that you started this job! :-)

Thanks! I am happy to hear that! Were working on everything to get ready, we move into our new workshop in November! We will tell you as soon as we accept orders! What will you be using the scanner for?

By the way, Archivar is able to to paperback-mode while still having the proper lighting! And we found another useful application for paperback-mode:
There are many children-books with thick pages, one won't be able to turn under the glass as they don't flex - no problem in paperback-mode.

Paperback mode is, i think, a term danielreetz brought up. It was intended to help scanning paperbacks which accidentally close whenever the cradle is lowered.

One can turn the whole Image-Module upside-down to have the glass pointing upwards.
That enables you to take paperbacks and scan them face-down (kind of like a regular flatbed scanner) while holding them in your hand instead of putting them into the cradle.

However in the latest archivist paperback mode was "sacrificed" for the best lighting. However with the Archivar you can take out the cradle and rest the lighting module upside down onto the small bars of the lift mechanism. You can then mount the imaging module upside-down and have paperback mode with perfect lighting.

David

Thanks, I was wondering if it would help me. I have a lot of paperbacks to scan. But this won't help me. My big problem when I am scanning paperbacks is the very narrow gutter margins a lot of them have. The traditional style, which your Archivar is a very nice adaptation of, can't scan down all the way to the bottom of the gutter. That means the end of most of the lines are cut off, which makes the proof reading and editing difficult.

I have switched to a single camera scanner that can scan all the way down into the gutter. viewtopic.php?f=14&t=3418 The scanning with mine is a lot slower so I keep trying to come up with a better way that will be faster.
