I have one question, which might be answered in post http://mightyohm.com/forum/viewtopic.php?f=15&t=562
, but not explicitly: is it possible to power the Geiger Counter board over one of the three header sets (Serial, ICSP, or the header set called "Pulse")? I want to incorporate the Geiger Counter into an Arduino-based logger kit (which shall also log other parameters in my home, such as temperature, humidity, light level etc.) - and would love if I could hook up the powering of the Geiger Counter to the Arduino (instead of always using batteries).
Best wishes -
