Andrew
It's just the link at the top of the page that doesn't work then.

Re: Wiki or Wikibook?

I've put the first couple of pages in a wikibook with what looks like the very basics to me.

http://en.wikibooks.org/wiki/DIY_Book_Scanner/main

Please feel free to add and correct it.

The advantage of the wikibook is they look after all the spam filtering etc.

Thanks John

Wiki or Wikibook?

Sounds daft but whilst there is a lot of useful information in the forum it isn't easy to find the basics. Perhaps a wiki book might be an idea. http://en.wikibooks.org/wiki/Main_Page Wikibooks are fairly stable and I think useful. The alternative is a wiki here but we'd need a first page for that t...

Re: Portable Build Lighting Question

I've picked up a Home Depot LED work light 15 watts and 800 lumens but I can't see a colour temperature on it. My first test image seems a little grey but after adjusting the exposure its much whiter and seems to OCR better. I assume once I get into CHDK settings and fix the length of exposure etc i...

Re: Questions on Building a simple paperback scanner

As a follow up in case anyone else has a A810 quote from the CHDK forum:

"ver.req method does not work on A810. If you are trying to discover firmware version to install CHDK, you can use ACID or STICK"

Re: Questions on Building a simple paperback scanner

Acid worked perfectly for the first one. I'll take a photograph with the second camera and get the version number for that one as well. Knowing the version is 100e I went back and tried the two keys once more. It told me I had a 16 gig memory card etc but I couldn't see 100e anywhere. Many Thanks Ch...

I have created both ver.req and vers.req in the root of the card. There is a center button marked "func set" ...

Re: Questions on Building a simple paperback scanner

If you put the camera as close as possible, then you won't be able to photograph a larger book from there. The image will also likely have some barrel distortion (at least it does on my A4000 when fully zoomed out). Personally, I would pull it back a couple of feet and use the optical zoom. If you'...
