Hello, I just finished mounting all elements end carefully followed all of the nice assembly manual (except serial settings). I have powered the circuit with a 9V 300mA adapter. But after one hour I see only 00.00 µSv/h. With the "select" button, and "Buzzer & Led On", I  can hear the radiation detections and see the led blink. But the Count CPM stay 00000. Is there some minimum settings to do before mesuring any radiation ? Or where I am wrong ? Best regards Dominique

I'm still waiting for the PCB, it may take a few days more since that virus ... as soon as the pcb's are fitted with the parts I'll post some pics. In the mean time you can have a look on github at the Eagle cad files, if somebody is interested I can post the Kicad files too. Grüss, Jacques

Nice work! I will use some of the code for my weatherstation. But I have one question. Where did you install the new sensors and the particle sensor? Do you have some images for me/us? That would be great!

Completed the preamp and have it connected to a Q-watt amp for testing  The sound overall is impressive but have one concern and that is the treble adjustment  There is none  Have connect a AC volt meter to the output to monitor amplitude  change while making adjustment to the treble .  Have not seen any change on either channel  Any comments or suggestion would be  Appreciated The bass amplitude voltage change is huge.
