This page collects efforts to develop a Raspberry Pi (#raspberry-pi) based spectrometer, building on Public Lab (and others') open source [DIY spectrometer designs](/wiki/spectrometry). ## Design goals The Raspberry Pi camera (especially the version 2 camera) is very sensitive and good resolution, very inexpensive (<$20), has very low baseline noise, and is extremely configurable. ## Software You can now [download ready-to-use camera software on our Pi Builder page](/pi-builder). ## Questions Questions can be either frequently asked questions, or "next step" challenges we're looking to solve. [questions:raspberry-pi-spectrometer] ## Activities Activities show how to use this project, step by step. [activities:raspberry-pi-spectrometer] ...
