Description
When a Townsend avalanche is created in a Geiger-Muller tube by some high-energy particle, the signal is inverted and sent to the trigger pin of a ne555 in monostable mode (T ~ 2s), whose output is sent to the clock-enable pin of a decade counter driving the cathodes of a Nixie tube, while the clock signal of the decade counter comes from the ouput of another ne555 in astable mode (f ~ 1-50Hz through UI potentiometer) Original idea : AlphaPhoenix (https://www.youtube.com/c/AlphaPhoenixChannel) Credit for voltage booster for Geiger-Müller tube : CAJOE (https://github.com/SensorsIot/Geiger-Counter-RadiationD-v1.1-CAJOE-)
