I want to share with the forum the machine that I have built.
It is based on an old 8mm / Super8 Ricoh Auto 8p Trioscope projector from 1975.
The reason for using the projector has been to have it available at home. It was broken and did not work as such a projector. Apart from this, in my case it greatly facilitated the task of transporting the film. It would not have been possible for me to build a machine from scratch, since although I have some manual skills, I do not have a suitable workshop.
So I removed all the unnecessary components from the projector and attached a new stepper motor with its corresponding driver.
The transmission is carried out by means of a toothed wheel and pinion, so that once the first frame is in position, it is only necessary to turn one complete turn of the main shaft of the projector to advance or back exactly one frame.
As you can see, the whole assembly can be closed with the original projector cover and I can have it on my desk.
I have recently modified the mechanical coupling to make the film transport faster and now it looks like this:

Finally a video of the system in operation:
