Abstract

A distributed cosmic ray detector was built and installed as part of the Splash Adelaide 2017 Winter Festival. Situated on the banks of the Torrens River in Adelaide, the 16 individual sensors would flash and emit sounds as muons were detected from cosmic ray showers in the atmosphere. In this talk we will describe the project and the software written to run on the Raspberry Pi Zero computer in each detector. The Raspberry Pi Zero runs Raspbian Linux and uses the WiringPi library to interface with signals received from the detector hardware. Ansible is used deploy updates to the wirelessly networked array. Code to run your own sensor is available on GitHub: https://github.com/PaulSchulz/cosmic-array.git
