Phyllotaxis: An audio-reactive LED display

A phyllotaxis describes a distinct arrangement of leaves some plants form. It is one of nature’s mesmerizing patterns and one that maker Jagi Natarajan is particularly interested in. In this project they created spiraling audio-reactive LED display. It has 89 individual cells each lit by an addressable LED. The project has already gone through two iterations with a third planned sometime in the future.

I’ve been fascinated by understanding patterns that appear in nature, through code. Communing with the inherent emergent patterns that exist in the universe.

The phyllotaxis is one such pattern, the expanding double-spiral shape that appears in the center of sunflowers, succulents, other plants. It’s surprisingly simple code

Celebrate a NASA Halloween

Hubble has photographed the “Ghost Nebula,” which has eerie, semitransparent flowing veils of gas and dust. The nebula is being blasted by a torrent of radiation from a nearby, blue-giant star. This animation flips between two views from Hubble. The more colorful image is taken in visible light where the glow of hydrogen gas looks pinkish. By contrast, the green-grayish view is in near-infrared light (IR) which only records light reflected off of dust. The nebula becomes more transparent and ethereal when looking at it in the IR, allowing for background stars to become more visible. NASA, ESA, and J. DePasquale (STScI) via NASA

Although this was published by NASA back in 2018, their lists, tips, photos and more pairing the mysteries of our universe with Halloween is still pretty awesome.

NASA Model Wing Lights Up During First Pressure Sensitive Paint Tests

Image via NASA

 

NASA is using special paint that glows under ultraviolet light to test airflow and pressure. The paint responds to pressure by glowing brighter. This is first test using the “unsteady Pressure Sensitive Paint” that has been in development for a few years.

Via NASA:

Unsteady pressure sensitive paint is a specialized coating that varies in brightness according to how much pressure the air flow applies to the wing. High-speed cameras capture those changes, providing data for computer models. For years, NASA researchers at centers including Langley and the agency’s Ames Research Center in California’s Silicon Valley have been working to integrate the paint into wind tunnel tests for aircraft and rockets. NASA researchers consider the paint a vital tool and expect to find many more wind tunnel applications in the future.

This test marked the technique’s first use on a large-scale, freely moving model in a low‑oxygen environment, an achievement made possible by the Transonic Dynamic Tunnel’s unique testing capabilities.

Articulated Pumpkin Spider – With Retractable Web Mechanism #3DThursday #3DPrinting

Bruddzz shares:

A Halloween pumpkin-spider hybrid with an ACTUAL retractable web mechanism. The abdomen houses a removable spool: thread webbing through the abdomen canal, tie it to the spool loop, insert the spool into the abdomen base, secure the bottom halves. Compatible with fishing line, floss, or any string. Includes resistance tabs to prevent web slipping. Standard version: 11.9 hours / 2 plates. A1 Mini version: 13.1 hours / 3 plates. Combines flexi articulation, mechanical fun, and prop-level presence in one Halloween piece. By Bruddz
