Of course I plan to continue to update this thread when I’ll have additional working things to show.
For the moment I have 2 blocking steps.
I need to make the axle hole on my reels a bit bigger as it is too small to put the reels on the projector (the projector’s axles diameter is 1mm too big).
And I have to construct a cable for the sound, the cable between the sound head and the Dolby processor needs to be shielded and have connectors at both ends (fortunately DB9 connectors are pretty standard). I’m just talking about analog sound, even if the sound head and the Dolby processor both support also digital sound, because this needs additional work, I won’t worry about it for now. (In the future I plan to support all sound formats, I even have a DTS reader which is the best sound format for 35mm film). Also another problem is that the Dolby processor doesn’t support outputting stereo, so I need to mix the multichannel line outs to have a simple line level stereo ouput.
I also have to clean all the sprockets and mechanical parts that handle the film. Even for small trailers, I’d like to keep them in good conditions. Because the projector was stored for a few years without special precautions about this before I acquired it, these things are not in perfect condition at the moment.
For the slide projector, I will just find a way to have it at the right height behind the projector during the tests, so nothing fancy. It is probable that it will just be sitting on a pile of various boxes.
