PublicLaboratory Mobile Spectrometer v3.0

thingiverse

Version 3.0 of PublicLaboratory.org's mobile spectrometer is now available. This scientific tool attaches to an Android, iOS phone, tablet or any camera with macro-mode capabilities and allows users to collect spectra for elemental composition analysis. Examples include light bulbs, olive oil, beer, etc. A new Version 4.0 will be released soon with a more refined design, available at http://publiclaboratory.org/notes/braddudenhoffer/2-11-2013/evolution-plots-smartphone-spectrometer-0. Assembly is easier than previous models and requires printing two parts (base and body with or without logo), attaching a film grating to the base, securing it to the body and mounting it on your device. Use SpectralWorkbench.org for calibration, saving and sharing spectra; an iOS app is in development. If you have an extrusion printer like a Mendel, support may be needed. Future versions will improve printing issues. All parts have been NetFabbed and verified. A 1000-line per mm linear grating from this source (tinyurl.com/9tjrz8r) or CD, DVD, or BluRay film works well as the prototype. The tool is licensed under CERN OHL v1.1 Public Lab contributors.
