This Compass Features a Familiar Mechanism Similar to Camera Apertures

Makers Cabinet

Kickstarter

Iris is a new tool for drawing and measuring circles. Simply rotate the rings to open and close its captivating aperture mechanism. Iris' concept came from conversations with our Kickstarter Community. Our supporters said that circle drawing tools lacked innovation and were difficult to use. These tools were unreliable and short-lived. So, we set out to completely redesign the circle drawing tool.

As amateur photographers, we noticed that camera apertures were reliable mechanisms and were surprised that they had not yet been developed for other purposes. In response to this observation, we designed an instrument that brings the quality of the camera aperture to your desk.

Iris is engineered using the most durable and effective materials. Its rings are machined from solid brass that patinas, improving with time and use. The leaves are resistant to ink and graphite, as they are stamped from carefully selected stainless spring steel that retains its shape. Iris houses twenty intricately designed leaves that enable you to create accurate circles with every stroke of your pencil.

In conversations with our users, we were inspired to add a scale along the side of the circle aperture. This allows you to effortlessly draw circles and measure diameters. The scale is marked with a high fidelity laser etching that denotes accuracy down to a millimeter.

Reminiscent of a camera's aperture enclosure, its scale is marked with a red dot. This allows you to read the diameter of your circle without the impediment of any other tool. Below the Iris' leaves sits a natural rubber footprint that seamlessly grips to your page. This means that all your focus can be on the circles you are drawing and not the instrument that you are using.

Great for making 20-sided polygons. Even with a ruler, it would be extremely difficult if not impossible to perform any of these operations:

They ballyhoo that their device does not put a hole in the paper. That is not a bug, it is a feature.
It does look great sitting on a desk, but I'll stick with my SUperbow

This is really nice. Rather than the heirloom steampunk aesthetic I'd like to see a cheap plastic one for distribution to elementary schools. I recently worked with a class of second graders on a STEM project that required a traditional compass to draw circles and it was nearly impossible for their level of coordination. Sure, a circle guide does the trick too, but this is quite elegant.
