Hi i desperately need the measurements for the disc in the optispark, im trying to manufacture a disc that allows me to use the disc as a single cam-sync signal but i´ve missplaced my own old disc!
Can anyone tell me the outside diameter of the disc, preferebly (?) in millimeters since i´m swedish

Right at 78mm. I saw this last night but wasn't trekking through the snow to the garage at 3 AM to retrieve it.
