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

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...

This is great test. How many millimeters from the lens front to the film?

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...

Try it, I wasn't aware of LS1.

Those are not likely a serial port. You need to find RX and TX pins/pads.

You are correct. Corrected Zip attached

v6.1 for type B & C In an attempt to make the frame more stable, dark images can now increase to ISO 200 (range 50-200), rather than a 16ms shutter time (4ms is the max in v6.1.) The console logging is improved to support this: Type B now has working exposure controls. In 6.0, the histogram...

Make sure you are using a 32GB or smaller card. Firmware updates only works from FAT32 cards (smaller media)

@domb84 Can you confirm you have a work serial port? This is 95% needed for everything that happens after. Mac84 has a excellent breakdown on adding the serial port (https://docs.google.com/document/d/1htmhRHyY_kEjoiTgSInV0PeXvzyXTMaXDYJ_3Ai4A4A/edit?tab=t.0 ). On the Reels serial port you...

Yes, but that only help once you have found an address or something to look for. Ghidra is not very helpful on it own, but a good C knowledge is needed.

Most of my methods and findings are documented in this thread. I used the serial port and shell to do memory dumps to find interesting data like the image size https://tinkerdifferent.com/threads/modding-the-kodak-reels-8mm-film-digitizer-firmware-hack.2897/page-13#post-35093 White balance was...

The best solution for the crazy shipping rate for international is using forward2me.com, it will get you a "local" UK address for free shipping from Scorpion, then forward to a US address via the shipping service and pricing you prefer. This also does appear to be the same lens...

Has anyone tried Vision 3 color negative with a Kodak Reels scanner? I'm now scanning my own home development Ektachrome, but Vision 3 is cheaper and higher quality (but negative.) It might be future hack to offer negative film support.

Are you planning a Lens upgrade, as that create the biggest benefit? I'm in the process of replacing the lens on my Type B unit, to match my Type C. I haven't set the mounting position yet.

Just fixed Type B (see above.) The link has been updated, Types B and C are now equivalent.

I have now Type B and C running all the current hacks, unfortunately the Type A (with the same changes) crashes on boot. I expect there is a device drive address change I haven't handled yet. My default (fixed/manual) white balance has moved to better match the modern film I'm scanning...

The Scorpion Vision lens is very good, but technically overkill for this system. We don't need a 10MP 2/3" lens, as the sensor is only 1/3" and 1600x1200 is only 2MP. So a 1/3" lens can work, the issue is it must be designed to be a macro lens. I went through a dozen (cheaper) lenses, but none...
