    @Mac84 This is the lens I used: https://shop.scorpion.vision/products/m12-lens-12mm-f2-10 Other 12mm macro-lenses might work, but this lens was the only one to have a 28mm near-focus example. You should use a locking ring, to help with focus...

    Modding the Kodak Reels 8mm Film Digitizer (Firmware Hack)

    New minor discovery, I found how to set the time and date (other every time via the shell - smrec st 2025/7/12 12:23:00.) I was annoyed that all my scans are Jan 1, 2022. These devices do not have a battery backed clock, so the best I can do is set the date to the day of the firmware build...

    Modding the Kodak Reels 8mm Film Digitizer (Firmware Hack)

    More work reliably to stabilize the frame. Even the stock FW is flakey sometime, so this is about stock reliability. Upgrade the auto exposure to be smoother when it needs to change, sometimes on a cut, but to nothing if the histogram is good (90% of the time.) Firmware v6.4 for Type B and C...

    Bug fix firmware release for Type B & C I have mostly resolved the frame stability issue, the one I demo'd here So no new features, just more reliable captures. Also Type B, the end of reel detection was improved. It turn out the longer shutter, and lower ISO, for lower noise, was causing...

    Modding the Kodak Reels 8mm Film Digitizer (Firmware Hack)

    I have not found an easy solution. My first unit (Build #1) was extra messy, this used the 5mm extension ring. This first design is more zoomed in, as the sensor board is raised only 6.5mm. While there is less cutting of the back plastic, the 5mm ring that you have is wider than the plastic...

    Here is Kodak Vision 3 negative (home developed) through my modified Reels scanner. Not too bad. The white balance was changed to 1,1,1.75 to remove the orange cast of the negative film. I spent a few hours trying to find the color matrix or some way the invert in the scanner, but that might...

    This is with the replacement 12mm lens, although it should help the stock lens a tad. As thjakob discovered, you might be able to move the stock lens closer for similar results.

    Type B is finally working fully (matching C.) The upgrade is significant.

    Modding the Kodak Reels 8mm Film Digitizer (Firmware Hack)

    No stabilization needed, you just need a locking ring: My Type C has the 12mm lens at 26mm, so the 8mm lens at 18mm, for a very similar resolution gain. Compression at a high bit-rate solves most of the image quality issues (with a new lens, or a moved lens.) JPEG is also a compression...

    I still have an issue with my Type B with 12mm lens zoom out to the max. My original Type C lens hack with a the lens slightly closer: Both unit are set to sharpness of -1.0. Yet the Type B still lacks resolution, and as weird sharpening halos (resulting in black dots in the lights.)...

    I wasn't every able to focus the original lens when moved too much closer. Also as you move the lens down, it hits the film loading tray. With the 12mm lens it is really not any lower as the the sensor board is higher. Why did you disassemble the unit to replace the lens? The Lens can be...

    Thank you for your feedback, and I'm very happy that you making your own white balance versions, and that someone it benefiting from the Type B port. I am aware that I've broken playback (all models), that happened so long ago, and I have no idea which extension did it. I'm probably not going to...
