This shows how to use trash-only geometric fabrication to make what I call my "C1" construction, the first construction of Action Geometry, the system I use as the basis to build all things. In the end we make the three C1 constructions which are documented here:
These are the building blocks from which I build the C2 construction, which is the cardboard Platonic Solids. And with those I can build up to C3, which is the three dimensional construction geometry documented here:
The problem with the previously published version of the C1 shape constructions is that you need a compass, and those are annoying to find, and generally cost money. Also the ruler using English units is not ideal. So how to I build up the tools of classical geometry from trash in a way that actually works but doesn't need some capitalist nonsense like a compass or rely on imperialist units? By using the following tools:
- clear plastic drink lid
- wood stir stick or other straight object you can write on
- my hand, either hand, or someone else's hand
Step 1: Get Basic Unit From Anatomical Measures
I use the length of my ring finger, the third finger over from the thumb, between the middle and pinkie fingers. I mark on the stick what that length is. I could pick any finger of course, but by choosing a body part and sticking with it I can repeatably build technology from this with some consistency internal to my own technical systems.
