Re: jck57's Automatic Scanner Build
What a smooth and mesmerizing contraption! Great job, and thanks for detailing the construction.

Scrapped platen design because I couldn't get enough air flow through 1/4" OD vacuum line. New platen assembly is based on vacuum-box work by Aegre Reminiscens:

Glass panes are secured with clamps made from aluminium extrusion scraps and angle. Lighting is 4 crees + buck puck based on work by Ryan_phx and daniel_reetz:

Small rectangular panes of glass fit into router-cut recesses under sliding camera holders.

Auto pager turner test. LED's are dimmed by applying 5V from Arduino through 800 ohm resistor to Buckpuck CTL wire. Obviously this gadget needs work on picking and flipping one page at a time.

Re: jck57's Automatic Scanner Build
HOly crap! This thing is amazing! Do you mind saying where you're based? If I ever get to where you are, I would LOVE to see this in person. Seriously cool!!!

Thanks, Dan. Just sent a PM with my secret coordinates. Drop in for a cold beverage and help brainstorm this mutha.daniel_reetz wrote:HOly crap! This thing is amazing! Do you mind saying where you're based? If I ever get to where you are, I would LOVE to see this in person. Seriously cool!!!
Re: jck57's Automatic Scanner Build
This is really exciting to see. Exciting enough for me to finally stop lurking!
Would a counter-pulse of air on the outside of the platen work to keep additional pages from getting pulled up?
It doesn't have to be perfect - even the commercial scanners aren't perfect at turning pages. If you can achieve high enough accuracy, double pages could be detected with real-time OCR of page numbers or something like that, and the machine could be reset when it skips. One person could thereby operate several machines simultaneously, which would obviously be a massive improvement over the current DIY technology for any large digitization projects.

Re: jck57's Automatic Scanner Build
Wow, that looks really great! I look forward to the end result.

Re: jck57's Automatic Scanner Build
This looks very very professional. I think I will steal some of the design from you.
The way you have the lights centered to achieve high light intensity is very good for taking pictures, I think.
It looks now more like a commercial scanner. Incredible.
When you have the time could you make diagrams for the wiring and a shopping list of the materials used'?
So I can go for shopping here in europe.
Amazing what people get for free looking around at their working place.

Re: jck57's Automatic Scanner Build
What you do is project a blast of air at the pages when you vacuum them up. It is not strong enough to overcome the force of the vacuum, but it is strong enough to peel away the other pages. The only problem you'd come up against is if the page is sufficiently porous that it lets through too much vacuum. But you look like someone handy with pneumaticsjck57 wrote:Not sure what you mean.
