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...

Help is a video of my progress so far, and request for technical help at the end. @Gewendell money will not help, I just the find enough time, and I'm looking for new leads to fix the remaining issues. If some with a Type C Reels unit, could test all the versions I've posted, to see when...

I'm sure somewhere there is an fopen(), fread() and fwrite(), to open a config file with user controllable parameters, rather than flashing builds custom parameters. But this I have not yet found. Once I have that, then I could build a small UI (if I find the button events) to set fps, white...

Hi folks, I'm still around and need to revisit more Reelz hacking. I finished scanning all my families 8mm and Super8 from the 60s and 70s, about 4 hours run time, so that took a while. So I needed new sources to continue this hacking hobby. So I'm now shooting my own modern 100D Ektachrome...

Stock lens Sharpness -2, when using the 12mm lens sharpness -0.5 (or 0.0). Exposure is not contented. Tint 0.0 (or your preference.)

All my updates are currently C version only. I do have A & B units now, but other projects (like work) have got in the way made progress on those model slow.

thank you. I wasn't aware of this sensor, it is another lead. I've been struggling to get a good scan on a particular reel, so there might be something that make it worse with some reels.

More things sloppy Where Reelz or Reels, both claim 8.08 Megapixels, yet they both using an Aptina AR0330 sensor, which is only 3.15 Megapixels. The video mode used (likely) on the Aptina sensor is limited to 2304x1296 (ever wondered where the 1296p came from?) So have the marketing is from...

I too very occasionally see the error on the top of the frame (~2% of captures.) That is more baffling, as it might suggest there is no good timing between the motor control and the frame grab. The socket feed is in motion a lot, there is very little time when nothing is happening. a) 100ms -...

I might need help to find the trigger for the motor step function (and/or the frame grab function.) Even on the stock lens and firmware, you will occasionally see some instability at the bottom edge of the frame. This is a rolling shutter artifact, as the frame is being grabbed, at nearly the...

Thank you for the feedback. You should switch to V5.8 as the also fixes the missing full range flag in the video header (more dynamic range without color correction, or it saves you the ffmpeg step.) The crude manual-ish exposure control is still a work in progress. There will be more tweaks...

The cam is not a circle, so the 1.5mm would on the lump side only. You could also only increase the lump only 0.75mm, if you decrease the opposite side 0.75mm, it is the difference in the displacement at different angles that creates the motion path.

I would be interested in any code you have found regarding the motor functions. I didn't see any sprocket movement difference between Super8 and 8mm, even though the there is ~8.5% difference in the sprocket gap (~3.78mm - 8, ~4.1mm - S8). So it is possible that just a cam change for 16mm...
