###Using your spectrometer

Once you've assembled your spectrometer and are ready to use it, plug it in and visit [SpectralWorkbench.org](https://spectralworkbench.org) to begin recording data with it. The web-based software works in the **Chrome, Firefox and Opera browsers** on most computers and Android phones.

###(Peer) Support

Public Lab is not a corporation; we're an open community of DIY environmental science researchers which you have just joined! The best place to get help is the spectrometry mailing list; to join, sign up in the form to the left. 

The spectrometry mailing list is made up of people like you, who are building and improving open source spectrometry techniques. Ask questions, look for help, and consider helping others too!

You can also post a question on this site; it helps to share some photos or screenshots of what you're trying to do:
