Re: [Frameworks] 16mm synchronizers with sound
Precision made clever modular synchronizers and I am pretty sure they made a 16 mm optical module. You could attach multiple modules of different formats as needed.

Re: [Frameworks] 16mm synchronizers with sound
Somewhere in my junk, I have some stand alone optical readers that you plug into a sqwawk box. I don't recall they were ever tested but you're welcome to have them.

Re: [Frameworks] 16mm synchronizers with sound
1. No, as far as I know, nobody has made a synchronizer with an optical head. Magnasync did make outboard optical heads that would plug into a squawk box for editing; they did not have any flywheel. I never saw one in real life, only at trade shows. 2. Yes, you can run the optical head out of a projector outside the projector. Supply 4V to light the exciter lamp (a 5V power supply with two series diodes to drop the voltage is a common solution) and take the solar cell output into a microphone preamp. It will take about 40 dB to bring the signal up to line level. 3. In the seventies there were a lot of JAN projector soundheads available on the surplus market. I tried to make an editing device using one, but I found that without the proper flywheel arrangement the flutter was so high that voices were almost unintelligible, and with the proper flywheel I could not start and stop on a dime (as is needed for editing) without scratching the hell out of the film. 4. If you have a synchronizer, why do you need optical sound anyway? Just take your optical track, dub it to fullcoat, and run it in parallel with the other stuff. The miracle of mag is that it's easy to put anything you want on it any time. --scott ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
Re: [Frameworks] 16mm synchronizers with sound
> Is it possible to remove an optical reader from a projector and make it run > independently? Theoretically, yes, but it would be quite difficult. The device would need to contain the exciter lamp, the optical pick up, a film path with rollers between the two, the power supply for the exciter lamp, and at a minimun the preamp section following the audio pick-up. Extracting all this from a projector and building it into some custom case would be quite a job. It might be easier to start with a projector that's relatively easy to open-up — a Singer/Telex slot-load for example, disable the functions you DON'T want — e.g. if you don't want projector noise, disconnect the motor; if you don't want a light beam, remove the lamp, etc) then devise a threading path so the synchronizer can pull through the loop through the optical reader section on the projector. (You might also have to remove a drive sprocket or two). ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
Re: [Frameworks] 16mm synchronizers with sound
Yes, the usual synchronizer/squawkbox setup is for mag. IB On Saturday, January 25, 2014, Rebekka Erin Moran wrote: > Hi, > > I am collecting 16mm synchronizers for an installation project.

[Frameworks] 16mm synchronizers with sound
Hi, I am collecting 16mm synchronizers for an installation project. Does anybody know if the synchronizers with sound heads are for reading Mag only or do any exist that also read optical? Is it possible to remove and optical reader from a projector and make it run independently? I have taken apart an old projector and am attempting to connect the optical head so that it can produce sound from a film loop without a projector. any mechanical information or ideas much appreciated. Also - please be in touch if anybody has any synchronizers of any number of gangs they do not need or want. Many thanks!! all the best, Rebecca ___ FrameWorks mailing list FrameWorks@jonasmekasfilms.com https://mailman-mail5.webfaction.com/listinfo/frameworks
