First time accepted submitter jywarren writes Ever wish you could investigate pollution yourself? Public Lab's recently announced open source kit aims to make it possible for anyone to become a "pollution detective" by comparing samples of oil contamination. Under the hood, the kit is pretty interesting. It uses the ultraviolet fluorescence caused by a Blu-Ray laser pen in oil samples, and includes a "papercraft" spectrometer to scan and classify oil types. The group's Kickstarter campaign is also seeking 50 early-access beta testers to help test and refine the kit before release.
