Re-engineered Iris Diaphragm.

Well i have decided to share with the world my newly engineered version of an iris diaphragm in the attempts to win a laser cutter, because i have a lack of tools and or money :( i cant make and post a lot of my ideas, BUT i tried my hardest to make this one because i couldn't contain myself any more. so i made it out of easy to use materials i could easily cut with a knife. so if i do win the laser cutter i will be posting more instructables and i will make a better iris diaphragm instructable for you to clearly see how it works.

Basically my new design is similar to the design people all over the world have been using for years in the fact that you rotate either the top or bottom disk  to make the iris open or close, also we will be in fact using blades but not even close to the kind of blades we have used before.

However mine is unlike any you have ever seen in the world before, in the fact that it can be any size and have anywhere from 3 blades to...... well how ever many you would need or want, and the over all design would stay the same no matter what. Mine also allows for you to open and then close it completely and when i say close completely i mean you can close it until there isn't any light allowed threw. and to top it all off the blades don't over lap thus creating no friction at all.

p.s. im sorry i couldn't post a video of it working because i just bought a camera i don't have a stand so i had to hold the camera in order to take the pictures but on the next step i will show it closing in each picture.

Step 1: Pictures of iris closing

ok well in this step, well its more like a page for you to see me closing the iris a little bit at a time.

I love it. So creative and cool! I am going to try this with thinner triangles. Hopefully this will mean they need to slide less, and thus the diameter of the outside circle can be smaller (or at least the inside diameter can be larger).

amazeing! i think i may want to build a tiny one and combine it with this (http://www.instructables.com/id/LED-Gun-Glove/) project!

if you have any questions about how to make your own please don't hesitate to ask me, and i would love to see yours if you made one :D i'm currently trying to find a place to use some tools to make a new one out of wood.

sorry? but you are not the only one who has invented such a cool stuff - http://www.youtube.com/watch?v=3w7SSUFHjWE

hmm i never seen that video and i searched every where trying to find something like this one i built. well i did build mine almost 2 years ago so that explains why i didn't see the video cause the video is only about a year old. well darn i was hoping i had something unique.

And thank you for showing me the video its cool to see it used in something.

The slide piece on back side of blades can be replaced with two pins?

I think two pins is easier to attach in blade than that piece.

[jordan21892]

well i guess for the materials i used it wouldn't work but maybe wood and metal would work if the pins where thicker.

this is very cool! It's totally different and I think better than the standard iris. The only down side is the straight sided leaves don't look as cool as the curved. I wonder if you could use the same operating principle but make curved edge on the leaves for the appearance. I have to play with this a little.

[jordan21892]

unfortunately you cant use curved pieces but you could in fact use way more than 12 like i did you could have like 100 which would make it look way more rounded than this one. but you would have to make all those pieces too.
