Pixel

A 3D-printable vascular-plant biofilter. Build it on a $200 printer, hack it on GitHub, share it. Sorbent media captures gases as room air passes through, while microbes supported by the plant's root system continuously degrade those compounds — fully documented under CC BY-SA, with open firmware for ESP32-C3.

Hack it. Print it.

Schematics, firmware, and assembly notes are maintained on GitHub. Three PLA parts (housing, tray, lid) print on a consumer FDM machine in roughly six hours; the bill of materials is a 5 V USB fan, a 3.7 V Li-ion cell, an ESP32-C3 board, and a starter packet of sorbent media plus a vascular houseplant. Telemetry streams to Aerobiome or your own MQTT broker.
