Homebrew Sensing Project: DIY Environmental Monitoring

The non-profit Public Laboratory for Open Technology and Science (Public Lab) previously won a Knight News Challenge in 2011 and received $500,000 to fund a tool kit and online community for citizen-based, grassroots data gathering and research. The second Knight News Challenge the group won, a $350,000 Knight award focused on health data, will allow the group to build and deploy inexpensive technologies for monitoring.

Connections between the hacker culture of the 1970s and emerging DIY science continue with the funding of the Homebrew Sensing Project. Born of Public Lab, this project aims to create low-cost sensor technologies for environmental research and monitoring. Following its namesake’s (the homebrew computer club) lead, this project’s participant composition complicates distinctions between expert and hobbyist or amateur.

The three individuals leading up the project are Shannon Dosemagen, Jeffrey Warren, and Mathew Lippincott. I was able to chat with Dosemagen, also a co-Founder of Public Lab, via email. Situating the Homebrew Sensing Project within the Public Lab’s effort tells us a lot about the motivations behind the project. “Public lab,” Dosemagen writes, “isn’t just a nonprofit that creates tools, we’re interested in creating a community.” Connecting with community organizations, NGOs, and research institutions they have created an extensive network that helps connect with a community and connect communities.

Connecting communities and providing a space for them to interact, Public Lab provides what Dosemagen describes as “a space where people with different expertise can interact.” This is a particularly important interaction among different kinds of expertise, including specialized technical as well as local knowledge, and reflects the efforts of Public Lab, Dosemagen tells us, to “recognize that not only researchers linked to academic institutions bring value and expertise to projects such as this, but that everyone can bring something to the table through the experience and knowledge sets that they have.”

Engagement among experts is demonstrated through the “barn raising” activities, events where members of the community come together to create something (be it tool or tutorials), Public Lab undertakes. Winning a another Knight Challenge means that the group can continue such efforts with the Homebrew Sensing Project. This project aims to address growing concerns about exposure to various human-made hazards and the associated risks, including health risks. To do this, the group wants to create inexpensive tools that can be used with mobile devices, allowing community members to take readings and analyze the information without the high costs associated with traditional lab testing. The group will undertake these efforts by refining their hardware and software platforms and developing new ones. As well, Dosemagen writes that a “portion of this grant will go towards supporting an outreach role and community partners,” which means that further community building and crossing of boundaries between communities will be part of this important initiative. If you’re interested in learning more about Public Lab or following this project you can find more information about the project in their news release.

Public Lab’s Homebrew Sensing Project extends their work on a DIY spectrometry project. The initial project, Dosemagen noted, began a few years ago and publicly “launched in 2012 with a Kickstarter” and the results have been impressive. To date, she tells us, Public Lab has ”over 2,000 accounts on SpectralWorkbench.org, over 14,000 spectral samples uploaded, [and] 750 members in the spectrometry Google Group.” In addition to all of this work, the group has “shipped 3,500 spectrometers worldwide that range between a price point of $10 and $70,” with the price point being a particularly notable feature in how accessible that is when compared with traditional spectrometers that typically begin at several thousand dollars.

  1. Hello there! This blog post couldn’t be written any better!
    Looking at this post reminds me of my previous roommate!
    He always kept talking about this. I will send this information
    to him. Pretty sure he’s going to have a great read.
    Many thanks for sharing!
