Jeff Maki is a creative technologist, researcher and activist whose work examines and interprets the ordinary systems behind daily life.
His work provokes audiences to take a more active role in the management of public and private infrastructure—systems that increasingly represent power in everyday life.
Jeff’s work has been funded by NASA, Google, and the National Science Foundation; he is currently working with Publicworks Office.
standpipes
Standpipes are the backbone of a modern fire suppression system. Often, standpipes connect to fire sprinklers, the latter designed to automatically douse a fire when activated by heat. Fire sprinklers are enthusiastically endorsed by those with strong incentives for safety; installing (or not installing) fire sprinklers becomes an explicit value judgment on human life, visibly codified into a structure.

Critical Infrastructure is a walking/field guide intended for people who, as they move through the built urban environment, want to see and better understand infrastructure—and what stories these systems tell.

Neighborhood Networks is a long-term research project that combines community arts, participatory design, informal learning, and engineering to articulate and discover how communities use, or might use, emerging technologies.
Neighborhood Networks is a joint project of the CREATE Lab and the University of Pittsburgh Center for Learning in Out of School Environments (UPCLOSE), and is funded through a grant from the Intel Corporation.
As part of my involvement with the project, I rode my bike roughly 40 miles over two days in Pittsburgh, Pennsylvania with industrial hygiene sensors. I used the Casella 360 noise dosimeter to measure and log sound levels, and the Vulcain SafetyPalm IAQ Monitor to measure and log carbon monoxide and carbon dioxide levels. GPS data was recorded with the Garmin Forerunner 201. The former two were rented from Field Environmental in Pittsburgh.
data collection
In the first ride, I put the sound dosimeter in my backpack, and clipped the microphone sensor to the back flap of my bag. The gas probe was put in the waterbottle pouch (mesh) of my backpack. I rode about 20 miles on this trip, at a normal speed. Results were good overall, but gas levels seemed to be uniformly low (and this seemed wrong)
For the second ride, I made a mount of cardboard to keep the gas probe out in the open–it would not touch any surface during use, and would have free-flowing air on the sides (where the sensors are; except for the stalk, which measures temperature). I also tried to go no more than 20 mph during the entire ride. This configuration seemed to work much better. I kept the sound dosimeter in the same place; it seemed to work well the first time. This trip was also around 20 miles long.
analysis and conclusions
I imported the logged results from each of the sensors, ran them through some custom scripts I wrote (available below) and plotted the resulting KML on Google Earth. Everything used, along with the output of the scripts (KML) is available below.

The results painted an interesting picture of the city, capturing some local ephemera: the Kenny Chesney concert, and the necessary traffic bringing people to it. In the screenshot of Google Earth shown above, you can see a large spike in carbon dioxide levels when I passed under the I-279/PA-65 overpass. I can only assume this overpass traps gas below it (it wasn’t windy on the day I rode), and the sensors picked it up. Also notice the increased levels along the riverfront: there were large numbers of idling boats and generators powering TV’s, radios and barbecues–again, all for the concert.
I think a “sensor ride” is an interesting way to experience each neighborhood in Pittsburgh (I passed through at least a dozen), and a more visual way to look at the issue of pollution: both gaseous and aural. Next steps might include visualizing the data by zoning classification or socioeconomic background, or including a personal narrative of the ride (i.e. “there’s a bus next to me now”) as part of the data.
friends of larimer
Friends of Larimer was initiated in collaboration with Alexandra Woolsey Puffer in the context of human-centered design methods and civic engagement. The project was created to encourage a more favorable environment for social change in a stressed Pittsburgh neighborhood.

The Carbon Defense League and MapHub exhibited MapMover as part of Making Things Public: Atmospheres of Democracy at the ZKM Center for Art and Media in Karlsruhe, Germany. The installation consisted of two parts: a system to collect field recordings in the city of Pittsburgh, and a physical device in Karlsruhe to display them.
