Brief update on Air Quality

[:en] Despite the drastic measure of cutting power to hundreds of thousands (and potentially millions more) of people in efforts prevent wildfires, California is burning again. And with fires comes smoke, enough to close schools across Los Angeles out of concern for air quality and further north the winds are projected to shift and will…

Solarcast Deployment: Los Angeles

Earlier this year we announced Solarcast and talked about some of the challenges we faced while designing it. Thanks to the generous support of the Annenberg Foundation & Metabolic Studio (as well as the longterm support of the Shuttleworth Foundation) we were able to create the first batch of these devices and have been deploying…

Solarcast: Behind The Music

We wanted to explain a little more about what led us to the development and release of Solarcast and some of the challenges we faced along the way. With the deployment of our Pointcast network we realized that a recurring problem with placing sensors was access to both power and internet for the devices we…

Introducing Solarcast

What is SOLARCAST? Safecast has gained a tremendous amount of experience since starting our citizen-based environmental monitoring program in March, 2011. The learning curve has often been steep, but always rewarding. Conceived and designed primarily by OG Safecaster Ray Ozzie, our new Solarcast device combines everything we’ve learned deploying our bGeigie mobile radiation sensors, Pointcast fixed radiation sensors,…

Air Quality Beta Kit

Earlier this year we announced that our first real batch of Safecast Air Quality prototypes were being tested out in the field. These were all one of a kind devices with different configurations to help us understand how configuration variables would impact the data collected. We’re excited to now expand that beta testing group with…

Safecast Air Prototypes

If you’ve been following along at home you know that at Safecast we’ve been thinking about measuring air quality for quite some time. More than once we’ve jumped in only to be disappointed with the results, pushing us back to square one. One of the key tenets at Safecast is that we must be able…

Burning brimstone: the why and how of measuring sulfur dioxide

Carbon dioxide gets a lot of press as a human-generated atmospheric pollutant, but while we have not yet even doubled its concentration in the atmosphere over the past three hundred years of industrial activity we have managed close to a hundred-fold increase in sulfur dioxide during this same period. Some sulfur dioxide gets produced deliberately…

Air Prototype Show & Tell

Last night at the weekly Crash Space meeting, Naim showed off the current, working, Safecast Air prototype during show & tell, as well as an example of a possible housing using plates. We’re calling the device the “canAIRe” and may actually use a can as the housing, but this was interesting to see in practice.…

Safecast Air: How do we determine what to measure?

How do you address the question of what should be measured in the air to help determine its quality in a meaningful way? As Safecast has been expanding its efforts into monitoring air quality we’ve been sorting out what to measure based on the following criteria: public health, environmental interest, and durability of the sensors…
