CCD/CMOS Camera Back

One of my deepest desires has been to "resurrect" my film cameras as digital. Is it at all feasible to construct some sort of relatively compact and usable CMOS or CCD device which can be attached to an existing camera that would yield high resolution images to be stored on a standard memory card? If so, could a diagram and list of materials be provided? I would prefer a full format sensor for use on a full format 35 mm camera, but a smaller format sensor would be acceptable for attachment to microscopes or telescopes.

The biggest issue with what you would like to do is that typical CCD sensors are a fraction the size of a 35mm film frame. In order for the existing optics to focus properly onto the sensor, it has to be located in the same plane the film would be. If you install a 1/3 inch CCD in a 35mm film camera, you will only be capturing a small portion of the field of view. Anything is possible with enough effort, but given the low price of some very good digital cameras these days, you are better off buying one than trying to convert something and ending up with inferior results.
