Hacking the Kodak Reels 8mm Film Digitizer (New Thread)

[milek7]

Looks like my EU supposedly-typeD scanner doesn't work with any of the type D firmware posted here, including stock. It shows this for like 5 seconds after hitting "Record" and then goes back to preview.

My serial number is J2925148BK01666. I flashed FWDV280-2 (after removing the "-2") without any issues. Seems these new numbers are D's.

Now I need to figure out how to changes the values...

Thanks , melw!

Absolutely I'll share it on here as soon as I've got it off the scanner.

I'm doing at least one pass of all the films I have (now about 3/4 of the way through) before I crack this thing open, in case I manage to completely munt it. They're pretty pricey here in Aus so it's not something I want to tackle without getting mum's films all done at least as well as the crappy stock firmware can manage.

I've stepped up my scanning schedule a bit, and knocked out about 10 reels today.

Hi ArgieBargie,

I hope your film scanning is going well. I just wanted to follow up regarding the original firmware dump from your A3026 unit.
My return window is now getting quite close, so I need to decide soon whether to return my scanner or attempt another recovery method.
Have you had a chance to extract the firmware yet, or do you have an approximate idea of when you might be able to do it?
I completely understand that you need to finish your family films first, and I do not want to pressure you. I just need to know whether the dump is likely to be available before my return deadline.
Thank you again for offering to share it.

Still curious if anyone else has a 100% confirmation on this stock number firmware version to use: J2925148BK00696

The J prefix seems extremely rare at this point, I havent seen anyone else mention having one with that prefix.

Did you end up trying out the D version? Just ordered a unit off Amazon, similar serial number: J2925148BK01099. From what I can tell it's probably a D but it hasn't been tested yet.

Posting a new Type D build for anyone who wants to try it. Same base as the last one, two main changes:

• Manual white balance. While recording, use the arrows to pick R/G/B and +/- to adjust (±16 coarse, left/right for ±1 fine). The setting is saved and restored automatically after a power cycle. Use RST to reset back default values.
• Card-stall now stops the reel. If the SD card can't keep up and the recording stalls, you still get the on-screen CARD SLOW / REC STALLED warning — and now the motor also stops, leaving the frame counter frozen on the last good frame so you can see exactly where it cut out instead of finding out at the end.

Also cleaned up a false "REC STALLED" that used to flash in preview after a normal stop.

Reminder: for the higher bitrate, use a FAT32 card, 32 GB or smaller, Class 10 / V10+. Big exFAT cards write too slowly and will truncate long reels.

Quick update on an issue I've seen using post #616 "D" version drop on an H2825 unit. It has happened twice now so I thought it might be useful to share.

The first time it happened at about 1900 frames into a 50 foot roll of Super 8 (~3600 frames total/roll). The display froze at that frame but the film kept advancing and appeared to keep capturing. I assumed it was just a glitch so I stopped the unit and restarted. I completed about six or eight rolls before it happened again.

The second time was again with a 50 foot roll and it froze at about 2400 frames in, same behavior. I paid closer attention this time and waited for the end of the roll to move through, not knowing if it was still capturing. At the end of the roll, the OK button and power button were not responsive, and I had to unplug the unit to stop the motor. The SD card did not have a file for the capture. I was using the same 128GB FAT32 formatted SD card that I had been using successfully.

Not knowing the cause, I've reverted to the post #605 firmware and went back to the 16GB FAT32 card.

So far, so good but @melw let me know if there is anything you'd like me to do to troubleshoot or try to replicate.

Sorry for slow response - been on the road and just today got back to this. I'm tempted to try also the large SD card + FAT32 combo - large cards with exFAT are not working well, and 32GB FAT32 should work without issues. I just shared an updated Type D build (#645) that has improved stall detection + support for stopping motor when recording frame counter no longer advances.

I can feel the pain of not getting 50 foot roll recorded and only finding out at the very end. While I can't say for sure whether it's the large SD card, I'd lean toward using the 32GB one, if it's large enough to hold the recording, just to be on the safe side. Even with improved record stall detection, it's not nice if the recording cuts in the middle.
