Nice work Kamel. The images that you posted clearly show the difference. I will work on disassembly instructions this weekend so that you can try the lens with the actual unit. BTW - where did you get the test clip. They are pretty expensive.
My update.
Reworked the camera mount and made sure that all sides are properly aligned:

Also rotated the board so that now the image does not require any rotation. This gives a more uniform focus.
Added an IR filer and here is the test picture:

Ran shadowing compensation and this pretty much fixed the pink glow:

The test film :
test patterns are branded wittner SMTE super8 ordered in germany. they are very expensive, unfortunately. But it's more convenient to see the definition of the captured frames.

I can give you a small piece of 10cm / 15cm because I do not have a lot but it may be enough for testing. We can agree on the terms privately Tell me

Yes I am interested Kamel.
BTW - when choosing the lens we should get higher F stop. Possibly even f/8.0. You get less light in but the depth of field is larger and this will ensure that the whole frame is in focus. The test picture I posted was taken with the 12mm Marshall lens:
https://www.bhphotovideo.com/c/product/1409672-REG/marshall_electronics_cv4712_0_3mp_12mm_f_1_8_m12_3mp.html
It has f/1.8 which is very wide and shallow depth of the field. That is why the edges are slightly out of focus.
Here is the test Wolverine shot (posting it again):
https://photos.app.goo.gl/XdUo2tAvgwnKhspT7
Imagingsource 12mm lenses are f/2.8 which is better than what I have but still pretty wide.

Here are the disassembly instructions. This is my first stab at it. Will need cleaning up.

Stan

Many thanks for your continued work, the PDF instructions are most generous of you.

Stripped mine down a few times, but for users who have never attempted to do this, to this level, the PDF is of great value.

Keep up the good work chaps!

Thanks Mike,
We are getting closer to the ultimate goal of having fully custom Wolverne. Have several camera and lens alternatives and a few more coming up shortly.
The stepper controller that I used is pretty good and quiet. Looks pretty good so far.

can I slow the scrolling of the wolverine ex: 1 image every 2 seconds and get the signal to each frame to trigger another camera ? I would like use the original motors and led. Just replace the camera with trigger. I do not know how to recover the signal at each frame stop.
I'm not an electrician but I want to tinker with my wolverine to have the best quality.

The mod kit that I am working on uses the existing Wolverine stepper and the LED. If you want to put the stuff together fast for testing I suggest the following:
- Use the new camera that you bought and the new lens. Mount with the proto board and some standoffs or long screws.. similar to what I did.
- Get the stepper shield.
https://www.hackster.io/voske65/arduino-stspin820-stepper-driver-2ae2d4
or
https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stspin-motor-drivers-and-motor-driver-solutions
- Run the LED from the existing controller

Do not use the trigger for now. Just match the camera acquisition rate to the stepper rate. It will be a hit and miss but should work.

I am working on the interface board that will drive the existing LED and run the trigger interface. So that is coming up.

with your advice, I will wait a little for your advancement. I have a trigger input on the imaging source camera. it needs 3.3v or 5v at each frame stop and the software saves automatically to the hard drive. but I do not know or recover on the Wolverine the impulse to each frame.

The trigger signal is 3.3V and may be able to drive the camera directly. But you do not want to cut the connector off to get access to the signal. On my board I have the proper mating connector and then wires that come out that can be connected to the camera. Using Eagle PCB tool but the library does not have the JST part so creating my own...

It is very easy on the source imaging camera to record the frames. the capture software exists and it is free. you just have to send an impulse at the moment of the frames stop. it would be necessary to divert the signal of Wolverine towards my new camera. but I do not know how to do it.

You can get one of these:
https://thesaberarmory.com/product/4-pin-micro-jst-connector-pair-male-and-female/
Not sure if it is 1mm spacing because I never used this particular one. They do not provide the specs.
If it works you plug in the sync cable (pics coming up) and you have the lose wires coming out. Will send you the pinout description and connection details shortly.

I already have a trigger connector for my imagingsource camera board. But, I do not know where to put it on the Wolverine board. you are more competent than me for that.I will order several connector of different sizes to test.Thank you very much for your help and your advice.

This is what you need to do.
Locate the trigger connector. Check the following picture:
https://photos.app.goo.gl/LFUEeKjdT2GKVEx59
Unplug it.
Plug the disconnected connector into the new adapter cable. Like the one I mentioned in the previous post.
Wire up the interface as shown:
https://photos.app.goo.gl/5m8jsykGVw8QNDzL9
You will need 3.3V supply.
Alternatively, if you have a male connector with wires for the receptacle on the Wolverine board, you just connect the blk to blk wire, yel to yel and grn to grn. Then connect the blk wires to you camera gnd and the yellow to the camera trigger. No external supply and components needed.

Ah! Thank you very much Stan. With your good advice, I will be able to advance in my tests.
I keep you informed of the continuation of my work

Correction:
The JST connector info that I posted earlier is not correct. The Wolverine connectors are most likely Molex Picoblade. Very similar to JST 1.25mm connector but not compatible with them.
This should work:

Tried a cheap lens from dlscorp:

Actually not bad at all:

Hello Stan,
it is already much better than the result with the original optics of Wolverine. moreover, wolverine reinforce the sharpness video signal. You have to see with macro lenses, you can still gain in quality, what do you think. If in addition we do not compress any more before recording, it will be all the better.

Hi Kamel,
This was a cheap lens. I have a better lens on order:
https://www.oemcameras.com/lens-tbl-12-2c-5mp.htm
Will try that also. Will also do a test video with the new setup and original Wolverine setup. Most of us no not like Wolverine digital artifacts in the captured video and the new setup should fix that. That, and the takeup motor control. BTW - I am almost done with the interface board design.

Thanks Kamel,
Here is my first attempt at doing the schematic for the interface board. Working in the board mechanical now.

and the BOM

it's very good work, but I admit that there, it goes far beyond my skills!
I ordered some small jst molex 1.25 connectors that you recommended. I am waiting for them to continue my tests.

Here is a little napkin sketch on how the trigger circuit works and why we need two resistors and a 3.3V supply. Hope it helps...

Great job Stan. For my part, I am creating new pulleys for Wolverine. The original ones are flat and scratch the movies. To improve the scrolling of the images I made them curved.
If some are interested, I will post on thingiverse and I will put links to STL files for those who want to print them in 3D.
