Non-commercial, 2Dvers3D project application to express the behavior of natural predators near herds. (Processing.org is one of my preferences)
Seismi-Woolf seismic sensor, except that the support to the use remains difficult to avoid diversions ...
(Teensy PJRC, are used for a large margin of maneuver, self-diagnosis, self-troubleshooting, analysis via the series).
I am a beginner and confronted with other constraints, material design (donkey carrying pack, canvases of rapprochement / night accompaniment of the herd, non-lethal ammunition such as flause 120-150m, ...),
Conflict with herders, herdsman (computer enthusiast? what do they mean?), FDsea (just a human pack, but very aggressive), with DDT (plus support, stability without hindrance to knowledge), OFB-ONC-ONF-oncfs ("you don't care he lives in the village", indirect threat extremely violating them, but especially their non-pro-human broad-mindedness).
