Open Source Tech Revolutionizes Water Pollution Testing Equipment
High nitrate levels in water cause the dead zones in the world’s largest deltas. Using too much nitrogen fertilizer wastes resources and leads to nitrate in runoff and water wells and an excess of nitrate in drinking water is a health hazard to infants and harmful to many animals. Current portable nitrate testers range in price and accuracy, from ballpark data at low price points to several hundred dollars for a handheld photometer. This new design is palm-sized, interfaces with a free Android app, costs less than $65 to manufacture and uses green chemistry for a safer and more accurate testing procedure. “This is a Popeye-approved reagent methodology,” Pearce jokes, adding that the enzyme used in the test kit is found in spinach and other leafy greens. “We’re replacing a toxic heavy metal with something that you eat every day in your salad.”

Open Source Tools Provide An Economic Advantage For Science
Free and open source software (FOSS) and the distributed digital manufacturing of free and open source hardware (FOSH) have shown great promise for developing custom scientific tools. For some time now, FOSH has provided scientists a high return on investment. In fact, my previous research in the Open Source Labreported substantial economic savings from using these technologies. However, the open source design paradigm has since grown by orders of magnitude; now, there are examples of open source technology for science in the vast majority of disciplines, and several resources, including the Journal of Open Hardware, are dedicated to publishing them.
