[Frameworks] crystal sync super-8

[Pip Chodorov]

Hi Jean-Louis,

In December I saw offered on eBay a Nizo that had been modified for 
crystal sync a few years ago by TFG in Easthampton, CT, and I asked 
our resident technical expert in Paris, Christophe Goulard, if I 
should buy it. That modification requires a large box to be plugged 
into the side of the canera when you want it to run exactly at 24. 
Christophe has been fixing and modifying Nizos for years, such as 
adding a button to adjust the ASA for the new film stocks, or 
bypassing the need for the small round batteries for the light meter 
by wiring them to the AA pack. He is also modifying Bolex cameras, 
adding through the lens light meters, or motors; he is planning a way 
to replace the xenon bulbs in Eiki projectors with cool bright 
LEDs... He thought about the crystal sync problem and said, "don't 
buy it - it would be very easy to make that circuit myself."

The actual crystal component is tiny and he has designed a circuit 
that can be printed on a small board less than an inch long that can 
sit inside the camera. The circuit will only work when the camera is 
set to 24FPS. He just has to cut the wire leading out of the speed 
dial at the 24fps position and solder in his circuit. It will be 
powered from the 9V battery pack with a transformer because it only 
needs 3V. It will check the speed two dozen times per frame, rather 
than once a frame as in the TFG modification. It will run at 24 point 
zero zero zero frames per second.

He will offer this modification to your Nizo for 160 euros (unless 
your camera also needs some other revisions).

We hope to offer some crystal sync cameras on our webshop soon. 
Christophe has been busy so we're down now to one S800 for sale but 
he has a series of Nizos that will be ready soon, and then he will 
start on the sync project, using an 801 macro.

Keep in touch if you are interested,
Pip
