I have started to build a system/circuit to capture old cine 8/super 8 using the Cinecap programme.
I am having trouble to get the IR receiver being triggered when a white blade moves passed the IR receiver.
(There are three blades of which I have painted one white i.e. 2 black blades will pass before the white blade is supposedly required to trigger the system)
For the system I used the following-
A cine projector that can run as slow as 3 frames per second (Eumig 610D).
The moment that the frame "stops" for a split second, you need your camcorder to record the image and these frames are put together by the Cinecap into an AVI file. So when the frame stops, a trigger needs to be activated. In this case an IR receiver is the trigger.
(I also tried with a microswitch, but the capturing was erratic)
My video camera is a 3CCD Panasonic NV GS250
I have done the following: I converted a mouse (acknowledge James Rueben):

Used the following circuit (acknowledge James Rueben)::

Connected to an IR receiver:
OPB608A

The IR receiver and all my connections (converted mouse; circuit board) are working well.
My finger, or any white paper triggers a signal which captures a frame via my camcorder on Cinecap, BUT, the paper, my finger, etc need to be very close to the surface of the IR receiver to trigger the signal.
As mentioned before, I painted one of the three blades white, which will hopefully be triggered by the white blade going past.(acknowledge James Rueben):

It only works when I bring the IR receiver very close to the stationary blade.
If the blade rotates at 3fps, it does not trigger a signal, although I bring the receiver quite close.
What is the solution?:
I can see two possibilities
1. Either put something on the blade ? white paper, other material which the IR receiver will pick up (this is where I need advice and this will be the easiest),
2. Or get a stronger?? IR receiver.
I feel that there must be a way to produce a strong input by means of some material to create the trigger. I used PVA paint.
Any advice will be helpful. Will try it out in the next week or two.

I need to acknowledge the help I got from James Rueben in this regard- he initiated the project, with the initial input fro Ronypony.
