Re: Scan Comic Books

I found the v.100j firmware on the shdk site but I did not find instructions on how to put it on my camera. I will try to put the SDM software on the old firmware. Maybe it will work. Mind you SDM is not ment to replace your original firmware. SDM is placed onto a SD card and then placed into your ...

Re: Fix Keystoning via hardware adjustments

Thanks to Spamsickle who provided a calculation for a standard scanner which has a 90 degree cradle. I now can calculate how the cradle will look like. And from there the total size of the base. See our discussion at Science! Or, a new page on the wiki for technical works I made a spreadsheet with c...

Re: Science! Or, a new page on the wiki for technical works

I have to say, though, that this seems to be going about it backwards. I've always begun with the size of the books I wanted to scan, and matched the sides of the cradle to that. Spamsickle, thank you for explaining. Exactly what I am trying to do. Lets have a look to one of the pictures from dpc h...

Re: Fix Keystoning via hardware adjustments

If you know the length (L) of the green line segment between the red and yellow camera direction vectors in the diagram below, then the vertical distance between those two lines (i.e. the amount you'll need to translate the camera) is simply L / cos(cradle_angle / 2). (The cradle_angle of the stand...

Re: Master Index of All Scanner Builds.

I hope you also have a look at the wiki, the link is on top of the page. And if you want to explore a few "how to build" pages have a look here: Scanner build list wiki
The wiki is still under development but there are a few already done to get you started.

Re: Fix Keystoning via hardware adjustments

Jay, Would you please be so kind to put your calculations into a spreadsheet? In such a way that when you enter some of the measurements it will calculate the others/result. Can you explain which theorum of Pythagoras you have been using? Have a look at Pythagorean Theorem to help you pick out the r...

Re: Science! Or, a new page on the wiki for technical works

Good morning Rob, Since you started the new Wiki page Science! and showing to be a crack in mathematics, could you make a worksheet which calculates sides a and b if one part (the lenght of c) of the cradle is given ? Preferatly when the angle of bc is 45 degrees. See picture below for the naming of...

Where to find glass or acrylic

I found 2 manufacturers of special glass and acrylic. Mind you it isn't cheap. Both are used at exhibitions and by artists. http://www.claryl.com/us/ for the us, look on the webpage for other countries and dealers. http://www.tru-vue.com/Tru-Vue/For-Your-Home/ same. Claryl, 2mm thick, will cost in m...

Re: Debate: camera positioning -- flexible vs. fixed

My suggestion is to have several points for the camera to mount. To keep the cameralens middle (imaginary crosshair) pointed towards the book diagonal center you need a flexible mounting position. The bookpage has an 45 degree angle, so the camera needs to be fixed in an 45 degree angle to ensure th...

Re: Do we actually need portable cameras ?

Update: I myself have to swallow my words. :shock: I have found something which enables you to take pictures with your phonecamera (i.e. Sony Satio) from a tripod. It is called in an advertisement in my country a Walimex with tableclamp, and is for sale for a mere € 2,50 without sending cost. http...
