Re: PVC pipe scanner with 100 degree platen

Are you referring to the post-processing step that is used to compensate for uneven lighting across the page? I'm not sure that would work very well for mitigating reflections because the reflection (glare hot spot) will cause the image to lose information on the page that can't be recreated by alt...

Re: PVC pipe scanner with 100 degree platen

When you order on eBay it's best to check carefully whether an item will be shipped from China, to avoid possible delayed deliver or worse. At least here in the U.K., items indicated as being shipped from the U.K. will sometimes actually be shipped from China. Scroll down on the page and look for th...

Re: PVC pipe scanner with 100 degree platen

Regarding the lamp, I was thinking that if the lower shelf isn't interfering with the illumination, you might be able to make a fitting that could be clamped within the depth of the shelf, against which another fitting supporting the lamp could be positioned flush with the front edge of the shelf at...

Re: PVC pipe scanner with 100 degree platen

Well, it's going to be very difficult to move the light anywhere anyway. With the shelves mounted on the tracks shown in the photo above, couldn't you albeit with some inconvenience, move the lowest shelf up temporarily when scanning? The tracks should provide an easy way to adjust the lamp height ...

Re: PVC pipe scanner with 100 degree platen

Having in your first post denied any practical ability with tools, I hope you are learning enough from your brother to have the confidence after he leaves to make minor design changes if they are needed... ;) I hope you brother is enjoying his visit other than the quite exceptional Washington State ...

Re: PVC pipe scanner with 100 degree platen

Regarding cementing the pipes in place when ready: The tube I was looking at last was described as being a firm fit into couplings, so you might not even need to glue them. The pipes in your photo look a lighter colour, though, so that might not be so applicable. And there is also the possibility al...

Re: PVC pipe scanner with 100 degree platen

I decided to start a new thread for the actual build because the old thread was really long and a lot of speculation and ideas. Excellent idea... :D My brother is here and is working on it, and today completed an initial frame for the platen. (See attached photo - from before he added the T bracket...

Re: a small story for my scanner

Thank you for your detailed comments, I hope they could be useful to Doranwen with his scanner build, which I think he hopes to start soon... :D

BTW Are your first two attachments above displaying as intended, at a quick look they seem almost entirely black?

Re: a small story for my scanner

95.8 degrees glass angle .the right plate it moves a little but no issues with the books. Was that angle planned rather than using 100 degrees? As you probably know, Daniel Reetz when he did some tests to investigate the reflection problem found 100 degrees to be optimum, I don't have a link to his...

Re: a small story for my scanner

Two questions about your platten design: Konos93a_e_a.png 1. Your platten angle is 100º ? 2. The way the two pieces are joined, with a sharp edge where the platten enters the book, doesn't cause any problem? Your design avoids the need to profile the edges of the acrylic or glass sheets which may be...
