Mechanical iris

After I finished the prototype and played around with it for a bit I truly understood how the mechanism itself works, thus enabling me to come up with parts that would ensure a maximum difference between fully opened and fully (as much as possible) closed iris. I decided I'd invest some time and draw the schematics for the parts I figured would perform well. I am planning to make a short tutorial on how to decide the number of shutters as well as their length to achieve the best results…

A Mechanical Iris Window With Porthole: In this Instructable I will describe the process of building a mechanical iris diaphragm window with a porthole into an existing wall opening. I've always appreciated old fashioned ingenuity where the mechanics were as much art as function and a m…

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 segm…

Make an iris diaphragm that can close completely. This post explains how the dual-plane iris design achieves a fully closing mechanical iris.

Mechanical Iris: I've seen lots of variations on the mechanical iris but not many plans for one. My 13 year old son and I worked on this together to figure out how it works and how to make one. We built several variations in different materials using slightly differ…
