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)
-paperclips

Step 2: Print out the paper

Picture of Print out the paper
I suggest that you print out more than one copy, incase if you mess up.
UPDATE: I finally made a real thing that you can print out instead of this image. Just print that out instead

Step 3: Cut it out

Picture of Cut it out
Cut the paper out, for the "cam wheel" only cut out a circle like the "brass ring" it would be hard to realign then again.
For the "combined" only cut out the shutter part of it
also keep the "extra cam wheel"s , they are need for alignment 

Step 4: Glue it on

Get the foam core, the piece in the first picture is too small, it is only big enough for one part.
Using larger foam core, glue on the cam wheel and brass ring separately(far apart), also from the extra paper you have, cut out an extra cam wheel and glue it on, it is used later on to hold the cam wheel together.

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.
dombeef (author)  LogicalParadox3 years ago
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!

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.

Good luck!
Win Guy dombeef3 years ago
I'm finished! I hope these pics get through okay - I used two layers of cardboard instead of foam, and it works great!

You work at Sears?
dombeef (author)  ___1 year ago
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.

any patches or pro memberships left?? :D
dombeef (author)  FrozenIce2 years ago
Hmm... Let me check.... I do have a patch left!
heathbar642 years ago
Very cool!!
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. :)
dombeef (author)  rojo.balloon3 years ago
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.
dombeef (author)  rojo.balloon3 years ago
Yeah, but only if you are pro
is a patch like a badge?
dombeef (author)  rojo.balloon3 years ago
yeah, it is on your page with you instructables on in
OK. I will check that.
dombeef (author)  rojo.balloon3 years ago
But you have to be pro first, you arent
oh ok.
So, pros give pros badges.
dombeef (author)  rojo.balloon3 years ago
Pros can give anyone badges
Badges?  We don't need no stinking badges!    :)


Understood. :)

i made one but had to use card instead of credit or gift cards so the paperclip cuttings broke off
dombeef (author)  Ojsmudge2 years ago
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
dombeef (author)  Ojsmudge2 years ago
Well if you get it working you will get a patch!

any one know a video
dombeef (author)  techxpert3 years ago
A video for what?

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 :)
dombeef (author)  techxpert3 years ago
It might take a while, I have a few more projects ahead of it.
