The Public Lab spectrometry project is an open source community effort to develop low-cost spectrometers for a range of purposes. All open spectrometry hardware and software efforts are welcome here! Join in by: * Reading about goals and asking great questions * Building a basic spectrometer using one of our starter kits * Trying (and critiquing) our community-made how-to guides * Posting your own how-to guides and mods * Building on others’ work; hack and remix the kits to refine and expand them * Submit your improvements for inclusion in an upcoming starter kit release or add-on * Serving on a Research Review Group for a 3 month period # Table of Contents ##Goals ##Experiments ##Hardware mods ##Builds ##Starter kits ##Software ##Using spectral data
