I managed to synch two Eiki 16mm projectors after a many month's research. I found my way with optical sensors that count the images per second and a Max msp patch to control the speed and adjust one motor to the other. The computer is linked to the projectors motors through an Arduino port.

It took me a lot of time and money to have the projectors adjusted and the patch developed, but I was very happy to see it work....

all the best,

Subject: [Frameworks] need help with dual 16mm projection

I am trying to rig up an installation involving one 16mm film loop that runs through two projectors simultaneously. Does anyone have any advice on how to synch the 2 projectors so that the slack remains constant on both sides? I think I either need to rig up a slave motor or slave one projector to the other.
Any advice?Thanks!Mariah.
