I also got featured on HackADay! Link: http://hackaday.com/2011/03/22/paper-mechanical-iris/ 

Please rate and comment!
I posted a picture Instructable of this, and someone wanted me to make an instructable.
This mechanical iris has 6 segments, I plan to add more, it is "upgradable", as for that I can add more segments and fix broken ones. It can open and close smoothly, and it had a detachable strap to make it a monicle but I broke it a while ago

New thing: the first 2 people who make this will get a patch!
Edit: Win Guy already made one! look at the top comment and you will see it. There is only 1 patch left!

Step 1: Supplies

Here is what you need:
-Printout, image below
-scissors and hobby knife(Xacto Knife)
-snippers or plyers
-foam core, I used 1/4 in
-credit cards or gift cards with no protruding objects( I don't know now many I used, but I guess i used 3-4)
I made two. One full size and another 3/4 scale. They actually nest in a pretty cool way.
Do you have any images of it?
I tried to put some up but couldnt get the uploader to play nice with my phone. Goimg to post them tonight. I built them for a pair of steam punk goggles I am working on. Thanks for posting my inspiration.
I think it is tomorrow where ever you are right now?
I'm in the U.S. Central time zone. In about four hours I'm going to post the pictures. I had some other things come up last night that kept me from it. I'm going to post the pictures of the two irises separately and then I'm going to post the finished product picture. The finished product has a full size "brass bottom ring" and a 3/4 sized cam wheel. This allows it to slide into the eye socket of a pair of goggles I already own for a simpler modification rather than having to build an entire new socket for the iris.
Ok, it sounds very cool!
Here they are. Just a day late. And a couple of hours off.
Wow, they look very good! The patch is coming up shortly!<br><br>How do they work out? It is really cool to see that the new plans that I made works nicely(it was originally an image but I changed it into a pdf a few weeks ago.)
Totally awesome! I'm gonna post pics as soon as I'm finished. I'll be getting a Pro membership very soon, I'll let you know when.<br> Win Guy
Good luck!
I'm finished! I hope these pics get through okay - I used two layers of cardboard instead of foam, and it works great!<br> Win Guy
Hi <br>How are you all?<br>Iam study mechanical<br>I want to make mecanical lirs <br>I need help and size <br><br>Any one can help me?
This site is very informative. Your site will be bookmarked for future reference.
cool- think this can replace the one in my nikon lens?
You work at Sears?
No I do not, I actually know a friend that works there and when these giftcards expired they gave it to me because it was no use to them and it was going to be thrown out anyways.
Cool, always nice to have some extra free stufff to play around with.
u wrote 3th, its 3rd
any patches or pro memberships left?? :D
Hmm... Let me check.... I do have a patch left!
Very cool!! <br>I'm definitely gonna play with this. Can you give more info on how you would actually design this, as in more than just print pattern and cut? Specifically, how to determine the size and shape of the leaves and the pin spacing, slot spacing etc. I want to design one to my own needs rather than just copy yours.
Someone I know made this out of metal and showed me where the idea was from and showed this page. I was shocked. Pretty good. I like it. :)
Wait, someone actually made this and told someone about it? They should have posted a comment, I would give them a patch
well they are not really a member. That person just looks at the creations people have. :) And question: are you allowed to give people patches. That is cool.
Yeah, but only if you are pro
is a patch like a badge?
yeah, it is on your page with you instructables on in
OK. I will check that.
But you have to be pro first, you arent
oh ok.<br> So, pros give pros badges.
Pros can give anyone badges
<a href="http://en.wikipedia.org/wiki/Stinking_badges">Badges</a>? &nbsp;We don't need no stinking badges! &nbsp; &nbsp;:)<br> <br> <br>
Understood. :)
i made one but had to use card instead of credit or gift cards so the paperclip cuttings broke off <br>
Hmm, did you try layering the card?(I think you are referring to cardstock?)
nope just a layer of card from a cereal box didnt work :( oh well <br>
Well if you get it working you will get a patch!
any one know a video<br>
A video for what?<br><br>Unfortuantly I gave this to a very special teacher that let me work on this and many other projects and he was leaving, I am making another one and when I finish I will make a video.
yay :)
It might take a while, I have a few more projects ahead of it.
what is this project for?<br>
Everything.<br><br>It was a challenge because I was bored and i had nothing to do over the weekend<br><br>Also no one ever did this before, i had to do it
is this project ... like IRIS in the human eye?? kind of?
It is kinda like it, that the eye opens and closes, but the eye doesnt move the same way that this does.
im still a little confused here, we print the PDF and make like 6 shutter pieces, the cam wheel like a circle to help with alignment and the top and brass ring on foam. maybe. also how are they layered? im thinking bottom, cam, then top.
You put the cam wheel the top ring and the bottom ring on the foam core. The top ring has the lines so when you glue the cam wheel parts on it, you dont get it aligned wrong. And yes, they are layered like this: bottom, shutter, cam, and then top. the top ring has the container attached to it, as in the step ahead. <br><br>I dont have it with me because I gave it to a teacher that left last year, so I cant post any new pictures or videos, but I can still help you with most of the other stuff.
i want 2 make a box with a iris on top so that u have 2 know where the switch is
Look at my paper diamond puzzle sketchbook, I am thinking of making that have 6 segments so it is more like an iris.
