    On my 16ST the buckle switch stops the camera when the film runs out. And this works quite reliably.

    While there may be oxidation on the contacts (ARRI later on added a optional ground cable to combat issues such as that), I would suspect your power supply here. You should do some measurements to make sure that it is not simply the supply voltage collapsing to 6.7V under the load of the camera motor.

    My 16St has such a ground glass installed, so I don't think that it is that unusual.

    "ARRI A 16 St E" is its exact product name. It also has the German writing "Quarz-Antriebs-System" on it which is just explanatory for what it does.
  5. Fabian Schreyer
    Yes, that is the motor that I was talking about. It is box-shaped for sure, but it is also quite feature rich and does everything (and more) that you asked for in the other thread.
  6. Fabian Schreyer
    You made a list of "Motors of interest" but did not list this excellent Crystal Sync Motor that ARRI made for the 16S. So I was curious if there was a reason why you would exclude that one.
  7. Fabian Schreyer
    Is there a reason for why you are not interested in the original ARRI A 16 St E?
  8. Fabian Schreyer
    I would add shutter parking to that list. Even the old original ARRI crystal sync motor does it, so I would kind of expect that feature on a more expensive device.
  9. Fabian Schreyer
    That is correct, of course. But none of the scratches that he has shown us could be from non-modified parts.
  10. Fabian Schreyer
    Sounds great! I might try to build it myself at some point 🙂
  11. Fabian Schreyer
    Do you still plan to release this project as open source?
  12. Fabian Schreyer
    I am not sure if I understand you correctly. You did research and found out that MP4 is not a container format but instead equals to h264 encoding?
  13. Fabian Schreyer
    MP4 is a container format for digital media. While the container can, of course, contain H.264 encoded material, the use of MP4 says absolutely nothing about which encoder was actually used.
  14. Fabian Schreyer
    That sounds quite interesting. Is there any written documentation on how to perform this kind of adjustment?
  15. Fabian Schreyer
    Andec in Berlin still offers this.
  16. Fabian Schreyer
    Are not all IICs also equipped with one bayonet mount? That might give you a few more modern options.
  17. Fabian Schreyer
    Of course not. I also would suspect that one of the belts has degraded and just fell apart.
  18. Fabian Schreyer
    Yes.
  19. Fabian Schreyer
    That is always possible via the auxiliary port of the A 16St E. I think the "mod" displayed here is just about prolonging the potentiometer leads, so the camera speed can be controlled from somewhere else.
  20. Fabian Schreyer
    Is the second picture showing your device? Looks like it has been seriously tinkered with.
  21. Fabian Schreyer
    Well, if you still need a Bolex, there is one for sale right now:

    I did about the same for my IIA. Had to cut the power cable just before the original plug, because it was shorting there... But I got away with it quite well by using shrink wrap. For now it just works fine! Still, should I keep using that motor, I will probably install a more modern plug at some point. These original plugs with their cables in them are just way to brittle...
  23. Fabian Schreyer
    That is quite interesting to me! I am trying to get an Arriflex IIA up and running at the moment, but I still have visible speed variations in the tachometer. I wonder if this might result in the same issues.
  24. Fabian Schreyer
    What an amazing and rare piece of kit. I envy the buyer a lot! 😀

    While I have no idea about the Lasergraphics machine, I think it would be interesting to just run that print on a well maintained projector with a calibrated optical soundhead (that has a flywheel) and record the output. I have worked a lot with projectors in the past and I can tell that the effects observed here can easily occur if a bearing is damaged or something else is not right in the soundhead. Some soundheads are more problematic than others. Regarding the Lasergraphics soundhead: Did anyone ever scan a 3150 Hz measurement film to measure the amount of flutter? If not, that would be quite interesting!
