[sane-devel] Most Hackable Scanner?

2009-06-12 Thread m. allan noah
unfortunately, there is no way to know how wide the sensor array will
be without opening the machine. I think you should be prepared to buy
a couple different machines. craigslist or ebay might be helpful
there.

Thanks for that! I have a LiDE around, but for my application, a film
plane that's closer to 35mm film (or a bit larger) is ideal... using
the linear array from a CCD scanner directly is what I'd like to do.

Are you trying to build a digital back for something like a medium
format body, or are you trying to build one of these panoramic
machines?

This seems to come up on this mailing list every few months, so you
could try searching the archive, but in general you will likely want a
CCD machine instead of a CIS machine. Smarter machines (like fujitsu)
do lots of self-tests and self calibration, and will not like being
dissembled. Dumber machines require more work from the software, which
you can choose not to do :)

I am trying to build a digital back for a custom camera, something
like a medium format camera.

Thanks. I see this question has been asked a few times with a few
different angles, but no one has really concretely recommended
anything or come back to report positive experiences with some
specific hardware. Bummer, that.

I did find your recommendation for certain "dumb" chipsets (GT* and/or
Genesys in particular). On the supported scanners list, I see that the
HP ScanJet 2300c has "complete" support and USB2. This sounds ideal to
me. In your opinion, is it a good hacking candidate?

I see... thank you again for your time and advice, and apologies for
not Googlin' the archives sooner.

I did 8x10 scanning back off CIS Canon Lido several years ago for Sinar P2, at 
that time there was no SANE Lido support and I had to hack quite a bit. 

Recently I've seen Lido support added - for $80 for scanner it worth trying.

Note - even after I made it work there were problems with few missed scan lines 
and some other image artifacts. 

I may dig for my old source, but I suggest give new Lido a shot.


PS. Also if anybody did something similar for CCD scanners - please post your 
findings.


Oleg.

[sane-devel] Most Hackable Scanner?

2009-06-10 Thread Daniel Reetz
Hi All,

My summer project is to build a scanner camera. I've done my reading
and Googling, and found a few people's projects.

I've seen the work by Wandel,
http://www.sentex.net/~mwandel/tech/scanner.html

Tom Sharpless,
http://home.comcast.net/~scancams/

Andrew Davidhazy,
http://people.rit.edu/andpph/text-demo-scanner-cam.html

and recently this one made from an epson GT-S620 (anyone know the
North American designation for that thing?)
http://hackaday.com/2009/06/09/130-megapixel-scanner-camera/

Basically, in a dream world, I'd have a scanner that did nothing but
move and read out the CCD blindly, all other processing being done in
software after the fact. To what extent is this currently possible,
and are you aware of any particularly suitable hardware candidates?
Low-cost is preferable, but far from a deal-breaker.

I have spent some time hacking on scanners in the past, trying to
disable startup checks and calibration sequences in hardware, and had
little luck. But I have a strong suspicion that most of my problems
come from using crappy scanners on Windows, and so I'd like to start
using SANE to get much more control over the hardware. I see from the
SANE site that many Fujitsu and Epson scanners have "complete" support
(http://www.sane-project.org/cgi-bin/driver.pl?manu=&model=&bus=usb&v=&p=),
but I'm not sure exactly what that means in terms of my project.

Any suggestions or advice would be greatly appreciated.

Sorry for the long message, and regards,
Daniel Reetz
