PCB muon detector ----------------- ** CHECK v2 HERE: https://easyeda.com/markus_jidoka/muon-detector ** ** Special Thanks to [markus_jidoka](https://easyeda.com/markus_jidoka) due to the nice improvements ** 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. The other parts of the projects are: - Led track pulse PCB: https://easyeda.com/sergiomtzlosa/coincidence-muon-detectpr - Geiger PCB tube holder: https://easyeda.com/sergiomtzlosa/muon-detector-tube-copper BOM Summarized: --------------- - 1xStep-up DC-DC (5v to 400v) - 1xCapacitor 10uF - 450v Electrolitic - 1xCapacitor 100uF - 25V Electrolitic - 1xCapacitor 10uF - 25V Electrolitic - 1xCapacitor 100nF - 3xCapacitor 1nF - 3xCapacitor 10pF - 3xResistor 1MOhm 1/4w - 3xResistor 10MOhm 1w - 4xResistor 10KOhm 1/4w - 1xResistor 390 1/4W - 1xResistor 330 1/4W - 1xResistor 240 1/4W - 8xDiodes 1N914 - 1xDiode Led 5mm - 15xClem connector - 3xGeiger Tubes (J308) - 1x74HC14 Logic NOR gate - 1x74HC02 Logic NAND gate - 6xDuPont Pins - 1xUSB Type B connector - 2xSlide switch - 1xResettable Fuse PTC RX50F (0.5-1A a 6VDC) - 1xLM317 DC-DC Converter Adjustable Linear Regulator Step Down
