PCB muon detector ----------------- Schematics designed by Robert Hart: http://hardhack.org.au/geiger_muller_detector Thanks to Robert Hart for his fantastic ideas, please check his site for further experiments: http://hardhack.org.au/ This project uses 3 Geiger tubes to create a muon detector, it also uses a step up boost DC-DC to convert from 5V to 400V for Geiger tubes. This main PCB has 3 led ouputs that connects other 3 PCB that holds a led to track the Muon pulse. The main PCB also has 3 outputs that send a 5v pulse when a muon arrives, this output is used to track the impact over an Arduino.
