Obliterate the Cost of Consumer Products with Open Hardware

If you're looking for free and open source designs to replicate on your desktop 3D printer, you have about two million choices. Because the open source ethic is rooted so deeply in the 3D printing community, many of the consumer products you would normally buy are already among those millions of predesigned products. You can download the designs and save a lot of money. My group has shown in studies in both 2013 (on a self-built 3D printer) and 2017 (on an out-of-the box 3D printer) that peer-to-peer sharing prosumers (producing consumers) gain an incredible return on investment: > 100% at minimum and more likely ~1000% by 3D printing products to offset purchases only once a week...

Open Source Tech Revolutionizes Water Pollution Testing Equipment

Press Release | Michigan Technological University | August 5, 2015

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.

Openpump – An Open Source Syringe Pump With 3D Printing & Bioprinting Potential

Te Edwards | | December 18, 2014

Openpump, an open-source syringe pump made to dispense fluids over a set period of time, is just like the syringe pumps used to administer medication in hospitals and laboratory environments.  Most often used to perform chemical or biomedical research, pumps like this open-source version could easily be used for 3D printing extrusion of paste or as part of a 3D bioprinter for outputting biological materials...
