Picture of Paper Mechanical Iris
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

Picture of 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.
dombeef (author)  LogicalParadox4 years ago
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.)

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)  ___3 years 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.

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.balloon4 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.balloon4 years ago
Yeah, but only if you are pro
is a patch like a badge?
dombeef (author)  rojo.balloon4 years ago
yeah, it is on your page with you instructables on in
OK. I will check that.
dombeef (author)  rojo.balloon4 years ago
But you have to be pro first, you arent
oh ok.
So, pros give pros badges.
dombeef (author)  rojo.balloon4 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)  Ojsmudge4 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)  Ojsmudge4 years ago
Well if you get it working you will get a patch!

any one know a video
dombeef (author)  techxpert4 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)  techxpert4 years ago
It might take a while, I have a few more projects ahead of it.
