Hello... I am interested in using the 363 camera board(s) for a project that would allow people to convert their old still film-based cameras to digital use (digital still camera, NOT motion). And before anyone points out the obvious, yes, I know that you can buy a full frame digital camera for probably less than this project would allow someone to convert an old Nikon F or a Canon AE or Leica M series to digital usage. But, it needs to be done and since no one else has picked up the baton, I guess I must be the one. There is a treasure trove of old lenses and cameras out there that are going to waste and a large portion of photographers who don't care about auto-focus, LCD review and other bells and whistles that are available whether you want them or not.

What I am initially looking for is someone who is very familiar with the circuitry of the 363 camera. It would help me a lot to be able to ask a number of questions on how to simplify the circuit easily. Much of the features of the 363 will not be needed and I want to find out what needs to be "tied to ground" or can be left dangling or open on the circuit and not be used.

Anyone? thanks George Chicago

George, I don't think there is anything you can really save on by not using some features. To build 363 camera you need 10353+10342+10347+10365 if mechanical shutter is not needed, otherwise - add 10368. Mechanical shutter may be needed if you have exposure times less that about 1/1000, that is needed because of the limited shutter ratio of the electronic shutter (some light still leaks while sensor is being read out).

If you have any specific questions about the boards - please go ahead, post them here.

Hello Andrey, thanks for the response...I'm currently reading the entire DVinfo thread and trying to get up to speed. The reason I'd like to "edit" features is to reduce the size of the boards needed. I'd like to fit the electronics into existing still-film camera bodies and as you know, they're pretty small. Your current pc board size for the 353,347 and 342 I think will work just like they are, but there's no room for the 365 and 368...although I have yet to try to mock up the pc boards for a physical fit trial...as a secondary comment may I congratulate you and your associates on your great work and I wish you continued success... George

By the way...I can't seem to find anything on the 10365 board...can you direct me to where info is? thanks...George

It is a power supply board for the 10342+10347 - CCD needs a lot of power for readout, vertical phase currents are in amp range. It seems this board was never documented on the wiki, as well as the other one - 10368, mechanical shutter driver. I'll work on it --Andrey.filippov 15:06, 26 January 2009 (CST)
