Cosmic Pi - a low cost distributed cosmic ray detector, based on
It makes the detection and analysis of cosmic rays accessible to
students, educators and ordinary people. It uses a specially designed
detector combined with the low cost hardware of the Raspberry Pi
computer for data storage and online analysis..
