The Raspberry Pi project that we've been fans of for quite a while now has hit a new milestone: Today, they announced that as of the last week in October, the project has sold more than two million boards. Raspberry Pi is anything but alone in the tiny, hackable computer world (all kinds of other options, from Arduino to the x86-based Minnowboard, are out there, and all have their selling points), but the low price, open-source emphasis, and focus on education have all helped the Pi catch on. If yours is one of these 2 million, what are you using it for? (And if you favor some other small system for your own experiments, what factors matter?)
New submitter isza writes "MobilECG is probably the first open source clinical-grade electrocardiograph with simultaneous 12-lead recording and Android support. It has been designed to meet all the relevant medical standards (ISO 60601-1, etc.). Manufacturing cost @ 1000 pieces: ~$110. I had worked at a medical device company designing clinical electrocardiographs for three years. Fed up with the unreasonably high price, cumbersome design, and dishonest distribution practices of clinical ECG machines, I started working on a high-quality ECG that is different. After a couple of failed attempts to get funding for the expensive certification process and completely running out of funds, I decided to publish everything under a license that allows others to finalize and manufacture it or reuse parts of it in other projects." From the project page linked: "The software is licensed under WTFPL, the hardware under CERN OHL 1.2," and a few words of disclaimer: "Note: the design is functional but unfinished, it needs additional work before it can be certified. There are also some known bugs in it. Most of the software is unimplemented." Conventional crowdfunding may have fallen short, but Isza has proposed an interesting bargain for working on the project again himself: that will happen if he raises via donation half the amount of his original $22,000 investment.
mdsolar writes with this excerpt from the New York Times: "Japan took a major step back on Friday from earlier pledges to slash its greenhouse gas emissions, saying a shutdown of its nuclear power plants in the wake of the Fukushima disaster had made previous targets unattainable. The announcement cast a shadow over international talks underway in Warsaw aimed at fashioning a new global pact to address the threats of a changing climate. Under its new goal, Japan, one of the world's top polluters, would still seek to reduce its current emissions. But it would release 3 percent more greenhouse gases in 2020 than it did in 1990, rather than the 6 percent cut it originally promised or the 25 percent reduction it promised two years before the 2011 nuclear disaster."
