“Oyarsa”, by Robert L. Read An Oil Paint Wheel 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 […]

The Glussbot, a Tetrobot invented by Public Invention. Invent in the public, for the Public Public Invention is a non-profit whose mission is to “invent in the public, for the Public”, and our first 43 projects can be found here. Our goal is to create humanitarian projects that conform to our mission, and to coach these

A hexagonal-centered toroidal 1.053-bounded regular tetrahedral simplex chain, discovered at the Mathathon by Nathan Gilbert. Public Invention’s First Mathathon 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,

The Mission of Public Invention is to “Invent in the public, for the Public” We invent things that help all people. We empower inventors, technologists, and students to publish, find, and collaborate on invention ideas through direct coaching, team formation, curation of work, publication, co-working and learning events, and, in some cases, material support. We

Ferrofluid is a suspension of tiny iron nanoparticles in mineral oil that behaves like a moving liquid magnet when placed in a magnetic field. It can now be inexpensively purchased at magnet supply stores like Apex magnets. It has some fascinating and beautiful behavior. You can use it to make a liquid piston with no

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

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. 3D Printing Flexible Robotics 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
