Volvelle Possibilities

Just a little doodle to set me thinking. Even limiting myself to concentric circles for the most part, I kept coming up with possibilities for using Volvelles. I started with the idea of surveying what could be done with a circle and a pivot. Information can be obscured, indicated, or illuminated with a Volvelle. The second circle below could be a changing face. I’m not sure how you illustrate or derive a function with such a thing. But, like I say, “just a little doodle.” Transparent colored circles could illustrate combinations and layered traces could illustrate circuits. The final Volvelle on the bottom right plays with the idea of a spiral around a pivot, that is a turntable. Is the needle on the top or the bottom? Is there a needle guide? Maybe musicians could use them to demonstrate a musical passage. Just run an amplifying stylus through the grooves and you have yourselves a tune. 

Binary Adding Machine

Matthias Wandel, an engineer who works in wood, created a binary adding machine, a wonderful thing, a thing that makes you think. I’ve seen a similar adder created with K’nex, but it wasn’t as aesthetically pleasing.

The K’nex binary adding machine uses hinged rods that work like logic gates. Xiaoji Chen created much better looking gates with wooden slats and rivets. She’s modeled the adder in Processing.
