DIY Water Sensors Workshop

This write-up is a bit tardy, but that’s what happens when the holidays hit. In December, I hosted a DIY Water Sensors Workshop at Autodesk Pier 9 in collaboration with the Center for Investigative Reporting.

I’ve been fortunate enough to work at Autodesk, first as an artist-in-residence (2014) and for the last few years, running their Electronics Lab and more recently their Simulation Lab (VR/AR). For the workshop, we hosted a combination of journalists and members of the Autodesk community.

The idea for the workshop sprung out of my Sonaqua artwork. The project sonifies (makes sounds from) water quality by testing for electrical conductivity (EC), which is an correlates to pollution — the more heavy metals and minerals, the higher the EC. It’s one of a number of measurements that scientists make in the field, along with indicators such as pH and Dissolved Oxygen.

That’s a brief summary of the artwork and what I wanted to do was make basic module circuit available for anyone to use. We breadboarded the basic circuit and within a couple of hours, everyone was up and running, making sounds from water samples that they brought in.

Working with the Center for Investigative Reporting (CIR) was valuable — afterwards, we got into a long discussion about data journalism. I was impressed with their breadth of projects and related works which include:

Sonifying the Seismic Activity in Oklahoma – tracks earthquake activity increases due to fracking

Wet Prince of BelAir – uses satellite data to find water-wasters during the big drought.

Cicada Tracker – a project by WNYC & Radiolab using Arduinos to predict the cycle of 17-year cicadas



After a few hours, the breadboarded circuits were complete! I mailed circuit boards, designed in Autodesk EagleCAD to the workshop participants a few days later. There are always production delays, but they did get the boards in time for the holidays.
