ESP8266 GM counter schematic + firmware was created by pablox
Hello, last week i rebuild my GM counter with Arduino NANO and W5100 ethernet module.
Now I used ESP8266 and circuit is a bit simplified.
Used tube Si22g
Schematic: schema.png (1302×1450) (pablox.net)

That looks great pablox! I love the case and front panel - looks very industrial. Nice work, and thanks for sharing the schematic too.
That PSU looks beefy. I bet that bites if touched wrongly.
I do have a question about the circuit/schematic; why are R2, R3 and R4 10Meg, when you could have used a 30Meg resistor? Same for R6, R7 and R8. They could have been a 10Meg resistor, or whatever is needed for the tube.
ETA: I have just realized this is a new version/upgrade of the version you posted a few months ago. Its looking much nicer, neater and tidier. A massive improvement.
