Peles Descartadas: Matriz

site: kombucha.lucas.mat.br source on GitHub updated

An experiment at the frontier of fermentation, art, and machine learning. A living SCOBY is kept at home, fed tea, and monitored by sensors that record color, weight, pH, and temperature over weeks. This data — extracted from a single organism — forms the training corpus of a tiny computational model, hyperspecialized in one specific kombucha. Useless for any other purpose. A beautiful waste.

Conceived in dialogue with Peles Descartadas (Discarded Skins), an installation by Augusto Batista (Guto) that presents cured kombucha skins fixed to perforated metal sheets — a denunciation, in organic matter, of the industrial worker's discarding by the machine. Matriz takes the denunciation one step further: from the industrial plane to the cognitive plane. Human labor replaced by the model — and the data that feeds this model extracted, like tea, from a body still fermenting.

Current state: Raspberry Pi 3B + Camera Module v2 shooting every 10 minutes, AC lamp switched by a GPIO-driven relay, Python indexer in Docker on the VPS extracting average color per frame, data in SQLite served live on the project's site. In development: temperature (DS18B20), electret microphone for fermentation bubbles, graphite electrodes + INA128 + ADS1115 for the bioelectric signal, and overnight sonification via SuperCollider.
