This post was co-authored with [Becki Chall](http://publiclaboratory.org/people/becki), also from Public Lab [Public Lab](http://publiclaboratory.org) is structured like many open-source communities, with a non-profit hosting and coordinating the efforts of a broader, distributed community of contributors and members. However, we are in the unique position that our community creates innovative open-source hardware projects — tools to measure [...] more »

The Public Lab community has been working on a cheap, open-source spectrometer for detecting environmental contaminants [for some time now](http://publiclaboratory.org/notes/spectrometer). Since the [last spectrometry post](http://www.pbs.org/idealab/2011/09/taking-steps-toward-diy-spectrometry-so-citizens-can-test-for-pollutants249.html), one year ago, a lot has happened, so I thought I’d take the opportunity to write an update on the project. Most importantly, we’ve just launched [a Kickstarter campaign](http://kck.st/PI9XOq) to [...] more »

Public Laboratory is made up of a diverse group of contributors, some working from their homes or garages, some from their workplaces or even university labs. What brings us together is the idea that open-source, collaborative development can result in inexpensive and accessible environmental sensing. But to many, the way our community operates can be [...] more »

Several Public Laboratory groups have emerged around the development of new tools for measuring contamination and quantifying ecologic issues. Among them is an informal spectrometry working group, which is attempting to create an inexpensive spectrometer. Such an instrument offers the possibility of detecting and even quantifying contaminants such as polycyclic aromatic hydrocarbons, or PAHs — [...] more »

For the past few weeks I’ve been working from Tbilisi, Georgia — the other Georgia — with a fascinating organization called OpenMapsCaucasus (OMC for short), which has been hard at work creating the first participatory, public domain road map of an entire country. Created by JumpStart International, and building on previous mapping work in the [...] more »

Last week, as the mainstream press reported on the worsening environmental and economic crisis that is the British Petroleum spill in the Gulf Coast, I and a small group of DIY mappers flew down to New Orleans to coordinate a grassroots, citizen effort to map the spill. Instead of helicopters and satellites, we deployed a [...] more »

I’m getting ready for day five of a two-week workshop for high schoolers at Beaver Country Day School in a suburb of Boston. The subject is my project, Grassroots Mapping, which helps teach people — often young people — around the world how to be activist cartographers and how to make their own maps. There’s [...] more »
