Clones Welcome in Scientific Hardware
In the inaugural issue of the Journal of Open Hardware I review emerging business models for open source hardware. Many of these models are borrowed from the free and open source software industry and will no doubt be familiar to you. However, traditional companies should also take a close look at adding open source hardware to their strategy. One way a company can start the transition to the open source way is to open source a single product to drive sales of its other products. A firm can open source the hardware they sell in order to expand the market of other parts of their product line...

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.”
