OpenGeiger is a project I started two years ago. The framework is a partnership with french Institut for Radioprotection and Nuclear Safety (IRSN).
Thought as a participative science project, on the of bricks is the developpment of a radioactivity sensor, connected to a smartphone, to consolidate geolocalized data on a web server. I am enthusiastic about the first production batch !
I have been struggling for weeks to get there. Here is the evolution of the sensor. The first version was on a breadboard (yes, even if it produces 380 V !). The first version shown is a troughole "kit" to be used by unexperienced citizens. The last shown is industrially produced:
The board is RFduino based. It is bluetooth 4.0 enabled, but can be used in Arduino IDE. This choice was driven by the need to keep something accessible to the largest audience. We do not want to make a sensor for "experts", but something everybody could trust (= something everybody can investigate and modify).
More or less, I have been working out half the stages described in the Seedstudio conference... After flashing the boards, here come the time for making something safe and easy to use:
