 Hello Oscar,
 thank you for the idea...however, the medium format area has been solved by the various producers of medium format digital backs. today, you can get a used digital back for a Hasselblad V series camera for a little more than $2000USD. But, the classic 35mm still film cameras have no such upgrade path available. The reason of course is that the major companies want to sell new equipment, which I understand. But there are many of us out there that want the possibility of bringing their old equipment back to life. Plus, and I think this is key, for many photographers the extensive features and menus of today's DSLRs are annoying and interfere with the classic photographic creative process. So...my project continues! thanks again for contributing your thoughts.

			George,

			Did you consider using a medium format twin lens camera like the Rolleiflex? Cameras like these are inexpensive, but high quality: http://en.wikipedia.org/wiki/Rolleiflex You'd need a 60mm x 60mm sensor of course, but you'd have something really special. Maybe you can fit the boards under the mirror, i think that's an empty space.

			''Yes, it does matter. Processor will be reset and reboot if voltage goes too low (hope no writing to flash at that time). But 3.2v battery will most likely fail during frame readout - the power is about 12W during this process. If voltage will drop, system will be reset. And generating CCD voltages from 3.2 will be very inefficient - I would rather start from higher, like 12V (or 18V-19V like in notebooks)--[[User:Andrey.filippov\|Andrey.filippov]] 19:41, 27 January 2009 (CST)''

	3. If I don’t want to expose a frame faster than 1/1000 sec then I don’t need mechanical shutter board (10368)...everything slower than 1/1000 sec can be handled by electronic shutter in the KAI11002 sensor, yes?		3.

			''Yes, especially if the exposure is even higher >1/100. Around 1/1000 they could be some visible vertical artifacts that in some cases could be software corrected--[[User:Andrey.filippov\|Andrey.filippov]] 19:41, 27 January 2009 (CST)''

Or does it need an additional memory board to be able to do this?

			''Total system memory - 64MB, currently we use 19MB as image buffer (for compressed images). It is probably possible to increase it, but you'll need to be careful and remove all the unneeded applications that use memory. That may be not so easy as you'll loose software compatibility with the default software and upgrades. And that is for compressed, not raw images. 1 raw image for 11 MPix camera will need around 22MB, you can fit maximum 3 of them in the video memory (64MB)--[[User:Andrey.filippov\|Andrey.filippov]] 19:41, 27 January 2009 (CST) ''

			Thank you Andrey...
			here's some summary questions that I've been working with Alexandre to formulate for the wiki...

			Let me see if I am correct in my understanding...

			1. The 10353, 10342 and 10347 are the core boards I need for a 10363 camera to use as a base for my digital still image camera (no motion needed).

			2. They will all work on 3.2v battery power (well regulated...no over power...no under power or does under-power matter?)

			3. If I don’t want to expose a frame faster than 1/1000 sec then I don’t need mechanical shutter board (10368)...everything slower than 1/1000 sec can be handled by electronic shutter in the KAI11002 sensor, yes?

			4. The 10353 (or 10363 as it is known when using the 11002 sensor) has onboard memory that could keep, let’s say, 20 full frame still camera raw images until downloaded to pc? Or does it need an additional memory board to be able to do this?

			5. when I have this all hooked together, will the camera be able to boot from internal memory to work as a true portable for 20 raw still images, or will it always need to boot from a pc?

			6. Do I absolutely need the 10365 power supply board and what is it's physical dimension? if it is the wrong dimensions for my needs, can I redesign to other physical dimension and will it also run off the 3.2v battery power or does it require more battery power?
