  The advent of microcontrollers with enough CPU power and with analog and
digital peripherals makes possible to design a complete particle detector with
relative acquisition system around one microcontroller chip. The existence of a
world wide data infrastructure as internet allows for devising a distributed
network of cheap detectors capable to elaborate and send data or respond to
settings commands. The internet infrastructure enables to distribute the
absolute time (with precision of few milliseconds), to the simple devices far
apart, with few milliseconds precision, from a few meters to thousands of
kilometres. So it is possible to create a crowdsourcing experiment of citizen
science that use small scintillation-based particle detectors to monitor the
high energetic cosmic ray and the radiation environment.
