Added features / changes in v7.110.306 @ 2019-09-07
===================================================
1. added option for logfile size on rpi
2. fixed no reboot if no ibeacon signal parameter on RPI, it was not active
3. added INPUTcoincidence device:
eg using 2 .. 4 geiger counters you can set up a cosmic muon detector, by requiring simultaneous (within coincidence time window) events by all used GPIOs
The coincidence time of INPUTpulses from different gpios trigger is 0.1 msec to several minutes.
this can be used to for FAST (msecs) detection of 2 events and up to several minutes
With these devices you can detect background radiation (electrons and gamma rays) and eg cosmic muons passing through all 3 tubes. -- these do NOT detect Alpha particles (they do not get through the glass)
In Dallas the detection rate for muons is ~ 1 per 40 secs as the active area is pretty small. The background event rate for each tube is ~ 3/secs +-
You can buy radioactive pieces (very low intensity) on the web ~ $5. Putting eg a mesh next to these detectors the rate goes up from 3/s to > 50/s
