Project documentation coming soon.
Planned release
A reproducible platform for quantitative color measurement
The project is intended to support Beer-Lambert law investigations, reaction kinetics, food-dye concentration, water chemistry, enzyme assays, and unknown-concentration experiments.
Hardware
Optical path, enclosure, electronics, BOM, CAD, and fabrication files.
Methods
Assembly, calibration, blanking, sample handling, and measurement procedures.
Software
Firmware, data export, calibration-curve tools, and analysis examples.
Evidence
Linearity, repeatability, comparison data, uncertainty, and limitations.
