Movie scanners are a useful resource for digitizing slides and negatives, and the Plustek 8100 that [Christian Chapman] had was capable, but limited to tiny format film only. Rather than pay out for a a lot more expensive medium structure scanner that could cope with 120 film, he modified his 8100 to carry out the identical detail with a combination of fantastic previous software and hardware tampering.
On the application side, [Christian] modified a driver for the Plustek 8100 so that it sweeps the scan head even more than usual. At the software amount, to scan medium format frames, it does a overall of four scans: just one for each and every quadrant. The results get stitched with each other in program with a thoughtfully-developed shell script that offers previews and handles failures and restarts gracefully.
Components-sensible, the scanning carriage demands modification to make certain almost nothing interferes with the scan head as it moves even more than at first built. Some CAD and 3D printing made brief get the job done of this. By the way, this components mod is an outstanding demonstration of one of the core strengths of 3D printing: the ability to make geometrically-uncomplicated objects that would yet be troublesome or impractical to assemble in any other way.
