Introduction

This page documents the construction of the video spectrometer.

This hardware design will soon be released under the CERN Open Hardware License 1.1. A draft agreement is under development here: http://publiclaboratory.org/wiki/ohl-agreement and should be complete in a few days.

Construction takes approx. 1 hour. Open-source software to operate this spectrometer is available at: http://github.com/jywarren/spectral-workbench
