Here’s a short video demonstrating 5 steps to making Steampunk goggles mechanical iris diaphragm. Once you’ve 3D printed the parts it’s relatively straight forward to put together.
8×10″ card, incorporating a 5 blade iris mechanism with a 3.5″ aperture, made of reflective card stock.
Opening the aperture reveals your message.
Message can be easily replaced, and the card used again.
I decided to do something today that I have been wanting to do for a long time; which is to stencil an image on the blades of an iris. This, I figured, has no real practical use – perhaps a new Iris Calculator business card – but none-the-less it would be an interesting effect to see. And as it’s Canada day today, what better image to use than the Canadian flag!
Have you ever encountered an iris diaphragm? What is an iris diaphragm? Perhaps you have always wondered how they work, or even wanted to make your own?
