The Fukushima catastrophe was followed by a scarcity in Geiger counters since many persons wanted to measure the radioactivity in their surroundings. https://en.wikipedia.org/wiki/Geiger_counter A group of scientists inJapan decided to build a new Geiger from scratch with an open source approach, using the new tools at our disposal now: GPS, Arduino for electronics, simplicity. Here Read More …

The NGO Trend in Africa has launched the www.open-labware.org web site. Different laboratory equipments such as micro manipulator or accessories enabling to transform a smartphone into a microscope are presented. They are build by 3D printing   using open source 3D files. You also find the most cited paper in plos.orgbiology http://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1002086  

Open Source Nanotechnology The following text was taken from the web site http://www.opensourcenano.net/ that is no more active: Open Source Nano is an invitation to participate in the innovations of nanotechnology right from the start. It is an experiment in making high-tech laboratory research something that can be improved and innovated outside the laboratory, by Read More …

Measure of turbidimetry is important for water quality characterization. It is then interesting to use turbidimeters in the field. For developing countries it should be rugged, affordable and its electronics should be made of easily found components.  Low cost Turbimeter published in Sensors 2014,14,7142-7155; doi:10.3390/s140407142 By Christopher D. Kelley 1,*, Alexander Krolick 2, Logan Brunner Read More …

Due to makers and geeks (and to the patent on additive manufacturing getting public) and to the creation of Fab Labs, 3D printing has emerged as a powerful method for prototyping, enabling low cost manufacturing from digital object files, with easy  modification with open source software. This is interesting also for ecological reasons since you Read More …
