  1. I am looking for some information (Google did not help much yet) on what the Arri 16SR expects to receive at the Fischer socket pin 8 "external variable speed control". I understand that grounding pin 5 to pin 1(signal ground) one can input an external signal on pin 8 to use different speeds besides the usual 24fps. But what voltage is expected at pin 8? What type of signal is expected, a sine wave at the frequency the camera shall run or a multiple of it? Or even a square wave, toggled on/off where the frequency of that sets the camera's speed? Any information will help me a lot, thank you very much!
  2. You will love this, see the short video below about the new prototype: Vimeo link to new prototype
  3. Thanks a lot, that's helpful! Will try to get those soon.
  4. I'd like to power a Bolex H16 MC-17 motor from batteries, I think I'll need 24V for 24 fps. Does anyone of you have any experiences what types of batteries would work reliably to use the camera away from a wall socket? How much current is needed? Maybe anyone has a link to such batteries so I could try to get them? Thanks a lot!
  5. Hehe, thanks for that, looks like I should really get that one 😉
  6. Ok, I understand. Right, since it already comes that way, should be safe to go back that way too.
  7. But wouldn't the fact that the exposed stock is on the daylight reel again help a bit to protect it against some light? Or not really much, as it won't be wound very tightly? I should get the fresh stock in the black bags anyhow, so I planned to put it back in there, then in the black plastic boxes and then several such boxes in a bigger 35mm can that I tape. That should do, right?
  8. So you mean that also on take-up side you'd use a daylight reel and put the exposed reel in the end back in the black box for shipping to the lab? So not to use any cores at all on either side of the magazine?
  9. Thanks, so I will use the daylight spool on the feed side and the collapsible core on the take up side. Do you agree that re-spooling the films onto cores may be a risk with regards to dust and that I am better off just not having the footage counter but a clean stock right out of the factory?
  10. Another question connected to this: I have seen that other cameras put signals like pulses for every single frame and such on a few other pins besides 7/9/11. Does anyone know what the other 8 pins on the Arri 16SR 11 pin connector will input or output?
  11. I will be getting a few 100ft 16mm daylight reels to shoot in an Arri 16SR. Now I am wondering if it would make sense to re-spool them onto cores or if I'd rather use the daylight reels directly. If I wanted to use cores, I'd have to spool the 100ft onto another reel, then re-pool that reel onto a core inside a split reel, am I right? The downside I see here is that I'd spool the entire 100ft twice and may introduce dust or even worse some scratches. From what I have read so far, using the daylight reels directly just leads to a louder camera, does anyone know of any other real issues that may arise? Besides that I was told by the owner of the camera (I will borrow it for two days) that the daylight reels cannot fit in the magazines. How could that be true? Isn't every Arri 16SR able to use them, as soon as you remove the core adapter you will then see a normal square thingy, similar to what Krasnogorsk, Bolex and the likes have, which fits the square hole of the daylight reels, right? What would you propose? Thanks!
  12. Could anyone please tell me how the remote start/stop is handled on the Arri 16SR? To my understanding, there is the 11 pin fisher socket and according to a diagram I have found, pin 7 would be used for start/stop, 9 for ground and 11 for +12.6V. Nothing more is mentioned there however. Is ground and +12.6V used to supply the attached etxernal device? How is starting/stopping achieved? Is pin 7 being pulled high shortly (To what voltage? Connected to pin 11?) to trigger a start and pulled again to stop it? Or is it signalled differently? Thanks!
