Re: A new scanner design using plastic tubing

It is looking very good ! I don't think the right side of the book support with the cooling racks will slip too much. Another way I have just thought of for positioning the right side of the book support might be to use that wonderful non-slip drawer liner that I've used on the book supports to stop...

Re: A new scanner design using plastic tubing

Hi Louroboros Thanks for your long message and questions. I have got a scanner in the house at the moment - normally it is being used in a library. So I am going to do a full measurement of the entire machine, which I will post. However I am away for 2 and a half days this week, and I am working ofn...

Hi Kurt

Sounds very interesting to make the scanner from wood. I would very much like to see photos of the finished product!

Re: A new scanner design using plastic tubing

I've made a couple of modifications to the latest version of the scanner. The main change has been a widening of the platen angle to 110 degrees. The main reason for this was that it opens the book just that bit more and thereby enables the cameras to see text better close to the gutter. This change...

I ask this because Using my Nikon 5200 DSLR it is taking 40 seconds using a fast SD card, and the files are coming out about 24mb. When...
