Submission + - Catch oil polluters with open source tools using the Homebrew Oil Testing Kit (kickstarter.com)

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.

Submission + - Investigate oil spills with the Public Lab open source Oil Testing Kit (kickstarter.com)

jywarren writes: The DIY environmental group Public Lab has introduced a Kickstarter for a kit to identifying the source of oil pollution, using simple open source hardware tools — a Blu-Ray laser and a fold-up cardboard spectrometer. They are calling for beta testers to join the project in order to solve key remaining challenges in the open source technique; beta testers will get early access to prototypes. Worried about crude or motor oil spills near your home? Investigate them yourself!

Submission + - Eco-hacker group Public Lab builds homebrew gas flare observatories (publiclab.org) 1

lizbarry writes: In many places in the US and internationally, gas refineries "flare" excess material in huge fireballs, sometimes burning for weeks. These can vent toxic chemicals and heavy metals into neighboring "fenceline" communities, and often do so at night when regulators aren't watching. Environmental DIY tech group Public Lab (who you may remember from the DIY Spectrometry Kit http://publiclab.org/wiki/spec...) has partnered with IOBY to raise funds for a network of monitoring stations, using their homebrew open hardware spectrometers to hold polluters accountable.

Submission + - Public Lab begins shipping open hardware smartphone spectrometer kit (publiclab.org)

jywarren writes: The Public Lab has finally released its Smartphone Spectrometer, a molded plastic attachment for Android and iOS which turns your phone into a 1 nanometer resolution optical spectrometer. Recent research published on PL's open science site shows a technique for identifying crude oil contamination with a blu-ray-type laser and one of their devices. Is this a prototype Tricorder?

Comment Hope it's compatible w/existing open spectrometers (Score 4, Informative) 41

There've been open source spectrometers for smartphones and webcams on Thingiverse and PublicLab.org for a few years: http://thingiverse.com/thing:49934, http://thingiverse.com/thing:125428


And a papercraft spectrometer for $10: http://publiclab.org/wiki/foldable-spec

The new project looks great -- I just hope the new project intends compatibility with the growing open/crowdsourced spectral library at http://spectralworkbench.org/ -- because the more data in there, the easier matching becomes.

Welcome to the open spectrometry movement!

Submission + - DIY camera hackers create photosynthesis camera (kickstarter.com)

jywarren writes: The hardware hackers at Public Lab (who brought us the DIY Spectrometry Kit and the Balloon Mapping Kit) have reverse engineered the LANDSAT satellite and produced their own open hardware version, hilariously dubbed the "Infragram". It can do false color photosynthesis imaging just like LANDSAT, and costs only $35.

jywarren writes: Public Lab http://publiclab.org/ has launched a project to democratize infrared photosynthesis imaging — the ability to measure plant health as NASA does with false color LANDSAT imagery — with an experimental camera for $35. Their design, called the "Infragram", is open source: http://publiclab.org/wiki/near-infrared-camera ...and along with publishing the modifications so you can adapt your own camera, they’ve launched a Kickstarter to put these cameras in the hands of geek gardeners, farmers, and DIY scientists.

lizbarry writes: Gardeners look out! The Public Lab has launched a project to bring infrared photosynthesis imaging — the ability to literally produce “heat maps” of plant growth — to the masses with an experimental camera for $35. They’ve also published plans under the CERN Open Hardware License, showing you how to make one yourself.

Submission + - Is Google SoC supporting the open hardware movement? (publiclab.org)

jywarren writes: Open source community Public Lab http://publiclab.org/ is a mentoring org this year for Google Summer of Code, meaning that you can now apply for funding to work on CERN OHL licensed projects from spectrometric matching to kite-photography georectifying. Does this indicate support by Google for the open hardware movement? Or the DIY environmental movement?

Submission + - Spectral Challenge: a 'Crowdfunded DIY X Prize' to detect pollution (spectralchallenge.org)

An anonymous reader writes: PublicLaboratory.org announced a challenge to "cheaply identify toxic contaminants in your neighborhood" using *only* open source, DIY spectroscopy The prize is crowdfunded, so if you think the goal is laudable, but don't have time to work on detecting heavy metals or carcinogens with a home-made spectrometer, you can back the prize with ca$h.

Comment Re:Unclear on the concept (Score 2) 62

The brass-and-wood "steampunk" version is limited edition, but only limited in that we're only selling 5 pre-built spectrometers. The designs are already online for most of these models and based on the early build photos and bill of materials you can build your own (under the CERN Open Hardware License). So it is open hardware -- have fun!
