Kev it is quite likely because I sent an angry email to Wolverine during my early motor failures and sent a link to this forum so they could see I was not the only person with issues.

Wolverine data also watch my you tube channel and 'dislike' my Wolverine failure videos [Eek!] [Smile] [Smile]

Mike.... why is it that I'm not surprised? [Confused]

When Wolverine stops using it's customer base for beta testing it's equipment, well, then they won't have anything to 'dislike'!

Hi all-I'm a new poster to this forum, though I have been following it for a while. I had some trouble with the Wolverine Unit I bought in January 2017, so this week I took delivery of a new until. Based on my reading here, I thought everyone might be interested to know there have been changes to the film path. There are now three tabs instead of two, spaced out across the film path. The new manual says its to cut down on jitter. Ran a few films and it seemed to help.

My Wolverine had the three tabs and was totally jittery and unstable! With film sprocket damage as well. So guess their quality control is rubbish and you either strike lucky or not!

My Wolverine has 3 tabs as well and has a jitter issue with the stock setup.
Started working on the new controller. Have some issues with the M12 lens mount. Hard to get the right size so ordered a bunch of them all different sizes from M12lenses. Also ordered a new lens from bh photo. It is a 12mm lens and according to my calculations it should give a better optical resolution but the proof is in the pudding - right. Will see how this new combination works out.

Hello Stan,
congratulations for your work this will help a lot of people like me. I am impatient and I will be very interested in your module. for the lens mount, I do not know if the hole spacing is 18mm or 20mm. for the camera lens I found a 12mm macro scorpion that seems very good. We will end up making this machine a good telecine.

Hi Kamel,
Thanks for researching the lens alternatives.
I bought several M12 holders and checking them now.
http://www.m12lenses.com/M12-Lens-Holders-s/61.htm
PT-LH008P works good with the Wolverine lens and RASPI cam
but the optical magnification is not enough as you can see from my previous posts. It covers only 50% of the HD image. Not sure if 12mm is too much. Did a spreadsheet and it says 12mm should be OK but will have to test it since I have several lenses here.
The camera mount is a bit tricky. It requires standoffs. Should have something tomorrow and will send an update.

Thank you for sharing. I am not as competent as you but I look forward to your advancement. I would like for the moment to replace the original lens support to put another lens of better quality. I will print the support in 3D. I have to do tests too, I have f8, f12, f16 ... The focus distance is very important. I can not measure it.
Otherwise we can calculate the lens on the sunex web site: http://www.optics-online.com/register.asp

Managed to fix the camera mount:

Used the 8mm lens with the new holder and the optical magnification is still not enough:

12mm lens should be pretty close. Here is my calculation:
https://drive.google.com/file/d/1-hXTxF7eOxKUawaIUkLS4dvfP0YH8TbK/view?usp=sharing
I tried your link Kamel but it seems to be limited to 8mm FL and lower.
The stock Wolverine lens seems to be around 4 - 6 mm. Will measure it by focusing to infinity and then measuring the distance from the lens to the sensor.

ndeed, the calculation of optics is not simple. for now I would just replace the stock optics to improve the quality. the sensor is a 3.53 MP cmos. 2304x1536. But the recovered image is in 1440x1080.
the cmos is a 1/3 '' and measures 4.8mmx3.6mm.
the useful dimensions of the cmos of stock are 2.99mmx2.53mm.
The distance from the cmos to the film plane is about 45mm. the format super8 is 5.79mmx4.01mm. a focal lens of f10 would be good but it is difficult to find in M12. or play with long rings ... To test.

Looks like a pretty good plan. One issue that you may have is the fixed distance from the film to the sensor. A 12mm lens will focus at around 18mm (focuses at 12mm for infinity). The lens that you are planning to get has minimum focusing distance at 28mm according to the spec. So, 28mm + 18mm is 46mm which is too close for comfort. I plan to use 12mm but in my case I can change the sensor to film distance.

Yes you are right. I wanted to simplify my mod for the moment. but I would like, as you, disassemble all and slow down the system to avoid jigs and skipping pictures (great disease of these scanners units). Of course, I would also like to record the frames one by one to maintain the maximum quality ... I do not know how to disassemble the camera board support to become independent of their system ?... that's why I'm very interested in your work and the kit you are preparing. Have you made a disassembly guide ? I need help. sorry for my english.

Hi Kamel,
The Wolverine camera and the controller are all on one board and there is no way of separating the camera. That is why I removed the camera/controller/display unit and slowly building my own. I still reuse the transport mechanism with the stepper and the LEDs and the main mechanical assembly including the housing and the mounting brackets.
I do not have the instructions yet because it is still work in progress but it is in the plan.
The main issues that I have are:
- Select proper IR filter to remove pinkish tinge in the image
- Try 12mm lens (on order)
- Drive LEDs from 3.3V source on RPI
- Detect sync pulses from the transport in RPI
- 12V relay for the takeup motor
- Update sw to sense the sync and drive the stepper

The main issue now is the pink color in the image - see:
https://photos.app.goo.gl/2nRmSDpbsds7hXFo6

Found the root cause:
https://www.ccdcmoslens.com/pink-glow-caused-difference-lens-cra-sensor-cra/
https://www.raspberrypi.org/forums/viewtopic.php?t=196297

Will try the correction mentioned in the links above. This could limit the amount of optical magnification. Alternatively go with a different cam.
