Hi Stan,
I hope you are well.
Thank you very much for sharing your work.
I see that you have work on the board as they say in France (very busy).
Thanks again for all your hard work.

[Stan Jelavic]

Thanks Kamel.

[David Brown]

Kamel, do you have any pictures of the front panel assembly?

You might still be developing it. I also have "work on the board", too many projects that have been neglected due to time/interest!

[Kamel Ikhlef]

Hello David, Yes I am still in development. I was very late because covid-19. Here are 2 images of my progress. Just tests... The final print will be dark gray or black color of course. I still have to redo the button control panel. I plan 2 versions : One to meet Stan's design with lever switches, and another with lockable buttons and led indicators. It is well advanced but not yet really finished.

[David Brown]

Kamel, no hurry. I also printed these and wondered about the 2 switch panels.

[Kamel Ikhlef]

David,
If you have any comments or modifications you would like, I will try to incorporate them into my final design.
will be happy to receive your feedback.

Looks pretty cool Kamel.
I ordered the capstan motors from uxcell a long time ago. They reported some quality issues and returned the parts to the manufacturer and cancelled the order.
Considering the present issues with capstan I decided not to provide the parts for it at this time.
Looks like the guys at work are getting an industrial 3D printer so when they open up the office again I could potentially use it for the capstan parts. Obviously will have to get my own spools.

The V12 board kits are still a go and will have them ready soon.
Will ship via USPS pickup due to corona.

The first V12 power cct assembled and tested.

Will continue with the power for the rest of the boards.

Then proceed with other components.

Kamel I have not yet assembled everything and I don't have any switches. I have more to do before adding V12 too. I'll let you know. I like the dust/light cover idea. In the past I blocked the room lighting when capturing with a book or box. It interesting to me that I already had some magnets that are very close in size to the recessed holes. I only enlarged the diameter to 11mm. They are 10mm x ~1mm and the center hole fit exactly.




Stan I've thought for some time now that you would need to place the capstan on hold. I have that motor on an Amazon list and every time I see it, it's unavailable. I got lucky.

I think the Wolverine shuts off if the film stops moving. I had bad splices that would catch on the left side of the gate and get stuck. The claw never damaged the perforations, but it never shut down for me. I was never gone more than 10 minutes. The alarm should get everyone's attention!

Glad you both have escaped the virus (so far)!

[Bruce Davis]

Hi all hope everyone is well, David I have had similar experiences with bad splices catching on the corner of the gate guide entrance, how would the Wolverine know to shut down if the film is not moving, surely it is not that sophisticated.

Hello Bruce.

Shutdown after a splice catches, that is something I remember reading or watching. It might have been here, Splices, curls, vinegar and the Wolverine Digital MovieMaker
by Robert Hudson (the man who started this thread) https://www.youtube.com/watch?v=fYQiHkMMf64

Sounds like that happened some time after film stopped advancing thru the gate.

[Stan Jelavic]

I noticed that with Wolverine but cannot remember the details. We could turn off the motor instead of trying to force the film forward. Actually it may be possible to get the motor monitor only without the motor and then turn off the stepper is the jam is detected. Thoughts?

V12 update:
Installed power connector on 13 boards yesterday. That was a heck of a job. Sitting in front of the microscope screen with the soldering iron most of the day. That is by far the hardest part to solder. Had two scrapped boards (ruined the PCB traces)
Will install the rest of the power up cct on all 13 today and test.

[David Brown]

Stan, slaving over a hot soldering iron all day, sounds tedious. Good to hear there is progress!

I couldn't answer Bruce's question on how the Wolverine could detect the film stoppage. I had a couple of bad splices catch and stop the film, but caused no damage. The claw never stopped moving yet did not tear the perforations.

There is a sensor that reads the claw and one that reads the S8/N8 switch. I don't think those can be used. Can the stepper motor be monitored for film movement? In my case, it never stopped.

Are you talking about another option to use without the capstan motor? I did just see there is a similar uxcell encoder motor on amazon. It would need a redesigned mount if it could be used.

I think I would prefer the Hawkeye to stop. I'm not in a hurry to digitize my film. I have been testing at the slowest speed I have and I think it might produce a more stable image. Not sure of that.

For actual scans I would first clean the film. That should also reveal problem splices or damage.
If after cleaning and repair there is still a problem, it would be the least effort to repair at the stopped position. Finding errors in post can take a long time to locate and re-scan the film.

But who doesn't like options! Stop or force forward. Don't know what kind of effort that presents to the circuit. Sure don't want you to redo all the soldering again!

But hey, there are kangaroos in downtown Adelaide and coyotes in New York city?????
