Line up the camera lens with your drawn guideline

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
