Phyllotaxis-inspired audio-reactive LED display created using custom 3D printed cells
Key points
- Phyllotaxis pattern generated with code for LED placement.
- Custom 3D printable cells designed using CadQuery.
- Each cell houses an RGB addressable LED.
- The display reacts to audio input.
Inspiration from Nature's Patterns
The project began with an interest in natural patterns, specifically the phyllotaxis pattern seen in sunflowers and succulents. This pattern, characterized by expanding double spirals, was translated into code to generate a point cloud resembling a sunflower.
From Digital Concept to Physical Object
The initial digital pattern was then conceptualized as a physical LED display. The idea was to place an RGB addressable LED within each cell of the generated pattern, creating a cellular LED matrix. This approach offered a more unique shape compared to standard rectangular LED matrices.
3D Design and Fabrication
To realize the physical display, cell edge data from the processing sketch was exported and imported into a Python script utilizing the CadQuery library. This allowed for the programmatic generation of 3D geometry for each cell. The process involved creating negative space for individual cells, cutting them from a total volume, and carving holes for the LEDs.
Modular Construction
The entire geometry was split into four quadrants to accommodate the build volume of a 3D printer. This modular design facilitates the printing and assembly of the display, which is intended to be audio-reactive.
