The Mission of Public Invention is to “Invent in the public, for the public.

Public Invention Project #40: A Wheel for Painting Very Thin Lines

“Oyarsa”, by Robert L. Read I probably should not have taken up oil painting; I have always admired art done with pen-and-ink, which produces very thin, precise lines. It is possible to make thin lines with oil paint, but it is difficult. One must either have a terribly steady hand with a very fine brush, …

The Story of a Public, Cooperative Mathathon

A hexagonal-centered toroidal 1.053-bounded regular tetrahedral simplex chain, discovered at the Mathathon by Nathan Gilbert. Two weekends ago, something rare happened. Thirteen people, sharing only a common interest in math, joined together from India, the Middle-East, England, Canada and the United States to solve real math problems. As might be expected, most of them dropped …

What to do when you hear about your idea: “That’s been done…”

A prototype of a flying machine, constructed by Václav Kadeřávek in Prague about 1860–1865 About twenty times in my career as a Computer Scientist and Public Inventor I have somehow informally presented an idea to someone or a group of people, only to hear them say, “That’s been done.” Sometimes they add some additional information …

Project #7: Color-block Font for Writing

Color is vivid. Throughout recorded history, it has been expensive to produce color compared to monochrome design. Writing systems, which have been constantly evolving since their invention initiated recorded history, have generally been monochrome. But now color is cheap or free, which raises questions: Is the next evolution in writing systems in the direction of …

Project #33: 3D Print Soft Robotics with PVA Molds filled with Silicone

Lately there has been a lot of interest in soft robotics. These tend to use pneumatics or hydraulics in fluid-tight chambers which change shape based on pressure. It is not easy to 3D print with flexible air-tight material. I have done it by using Ninja Flex and then treating it heavily with Methyl Ethyl Ketone …
