## What it is
An open-source visible-light spectrometer project providing hardware schematics, bill of materials, and Python scripts for a DIY instrument built from a webcam, lasercut parts, and LED lighting. The device connects via USB to a computer where the included scripts run experiments and take measurements.

## Use cases
- build a DIY spectrometer from affordable parts
- collect spectral measurements with a webcam-based instrument
- teach students about spectrometry and analytical chemistry
- run reproducible open science experiments
- learn scientific programming through hands-on instrumentation
- analyze light spectra of samples as a citizen scientist

## When to choose
- you want a low-cost, fully open spectrometer for education or hobby science
- you need hardware schematics and software you can inspect and modify
- you are teaching reproducibility and open scientific instrumentation

## When to avoid
- you need lab-grade precision or calibrated quantitative spectroscopy
- you want a turnkey commercial instrument with support
- you need UV or IR spectroscopy rather than the visible range

## Facets
- artifact type: application
- maturity: maintenance
- function: data-science, developer-tools, simulation
- domain: hardware, education, chemistry, analytics
- platform: windows, python, cross-platform
- tags: spectrometer, open-hardware, open-science, citizen-science, analytical-chemistry, usb-instrument, diy-science, linux, macos
