[Frameworks] AC lock projector

[todd eacrett]

With the projectors facing each other, the inching knobs turn in opposite directions, so some kind of differential reverse gimmick would be required. Easy enough with bicycle chain and cogs.

      You can also use a flexible shaft — might give you more, um, flexibility in positioning projectors — or use chains and extra sprockets to redirect the chains.  Then again you could replace the motors with steppers and lock them together….

if you scroll don you can see images and video and text about the piece as it was installed 5 years ago. i'm thinking of reprising it this summer but got some kinks to work out....

      Mariah, can you share the details of your show with us? Sounds interesting...... 

Also: "If you link the inching knobs together with bicycle chains, you can
mechanically synchronize any number of projectors, just be careful
starting them and don't get your fingers caught.  Used to be very
common for 3D showings.

Wow how amazing. Any pictures available of how this was done?
