After a little more research, I have managed to improve my Cardboard Aperture greatly!
This Instructable is based off of a project of mine to design a working aperture out of around-the-house materials. I had just seen an awesome set of Steampunk goggles by Gogglerman that had a very nice brass aperture in one eye. I set about trying to figure out how it had been made, and my resulting project went through two design iterations before I had anything working. I then posted that as my first Instructable.
So, instead of just editing my first Instructable, there's enough different to create a new one, which I have done. This time I'll be posting some instructions sheet downloads (in *.psd and *.pdn format for compatibility with your checkbook) and more pictures. Perhaps even a video!

Signing UpStep 1: Designing your Parts
While not really the hardest part of this build, designing the parts is a crucial one. I've attached some files that should really help you out. I mainly used a compass and a protractor to design the parts.
The first part is the holding and hinging ring. Since my aperture was designed for six 'arms' I set the hinge holes 60 degrees apart. If you want more arms then you'll need to reposition the hinge holes. Use this widget to calculate this angle if you are lazy like I am don't want to do the math yourself ;)
The next part (looking like a rib) is one of the actual arms that swings in and closes the aperture. Each one should encompass about 100 degrees. You'll see how the hinging and swinging pegs are attached later.
The last part here, the one shaped like the hinging ring but with notches instead of holes, is the adjuster ring. The notches will 'grab' the pins on the upper face of the arms, pulling or pushing them around the ring.

Like I've said, though, my old design doesn't work very well. I'd love to see my new design in this material though!
Have a nice day,

I'm not even angry.
I'm being so sincere right now.
Even though you broke my heart.
And killed me.
And tore me to pieces.
And threw every piece into a fire.
As they burned it hurt because I was so happy for you!

...but look at me still talking when there's science to do.
I saw this and didn't even think of cameras, I thought of Aperture Science.
for the good of all of us
except the ones who are dead
Thanks, and have a nice day,

I will make a slideshow about it later on.
Good job though!

As for 100 degrees, if I remember correctly it was so that when the arm arced around the center of the ring (closed position) it would reach the other side without being too long. Or it was because it needed to be over 90 degrees without being too long as to be unmanageable, I don't remember exactly lol. should have kept notes..
Have a nice day,

I should point out, however, that it isn't an aperture, it's a shutter or diaphragm.
The size of the hole is the aperture.
Plus it sounds cooler :)
