Help creating a cine projector for capturing cine film?

Hi I would like to know if anyone has any experience of creating a cine projector for the purpose of capturing cine film? I have recently used a company in England called and although their service quality was excellent, I have quite a few films and it would be great to create something I could do myself. if anyone has any experience it would really help!
3d printing and the new raspberry camera, and then a raspberry Pi computer with the correct programming, and so on.

I have heard mention of someone looking to do exactly that with the new camera from them. Do a web search.
One could do an 8K scan, when the gear is up and running. Not too tricky.... but some adjustments as to color neutrality and light levels, light control, and so on... need be considered, in order to keep the camera sensor at it’s peak fidelity point.

Even though various types of ranges are stated, the sensor will have a ’best’ point in that range. Thus the light source, etc, have to be optimized for that peak point and then the scan can be slightly adjusted for the specific film negative or whatnot.

I’m confident that I could, if determined, build a very nice one, but that would take a lot of effort and a small bit of research, etc. This sort of job takes a cross of skills, a bit of lore across multiple fields, in order to do it justice. I know nothing about the Pi computers, but I have many years of programing experience through that sort of entire PC hardware pathway, but that was over 25 years ago. The rest of it, the mechanics, the electrical, the light engine design, etc, I know at the core design and execution level. It is doable, but not for the fainthearted, if one wants to do it right.

This new sensor from them, will be used for astrophotography, and probably is already. Where the image collection is similar to cine scanning, so some of the programming for image capture will be done for you already.
understanding dynamics, this might help a bit...(plenty of places to look on the web)
For the best in dynamic range, a more expensive modern sensor/hardware system maybe the way to go, ie a finished and working DSLR, but that would take you on a different design and build path. Specifically a camera/ lens combination for close focus or macro use. and TOTAL manual control, via a port.

People have done these various things and published on it... so start searching in these given directions mentioned din this post. 

You may get to being close enough for your desires in fidelity for fairly low cost and just slapping something together, so don't necessarily try to go down the 'full bore-full lore' over the top complexity road that is open to you.
