    ESPGeiger ESPGeiger ESPGeiger!
    Why are you prattling about with coding your own ESP8266 or ESP32 to run a Geiger counter when you can simply run ESPGeiger! Yaaay! 😄 I actually mean that. Stop messing with code that will give you only what you want. Choose ESPGeiger and get all the beans! I'm joking, but now seriously, ESPGeiger is good. No, it's not just good, it is fantastic! Let me tell you why. The first thing is as of the time of writing, ESPGeiger is currently under development, meaning as you read this, Steadramon may be bashing away at his keyboard making it better. Steadramon is the guy that wrote ESPGeiger and

    Adding live high voltage reading to the modified GK Radmon Geiger counter
    Modifying my GK Radmon kit Geiger counter to run ESPGeiger firmware has gained a little interest in it. John (BroHogan) the creator of the GK Radmon and other kit counters caught wind of this and appears very happy for me to be slicing and dicing his work - all in the good spirit of things, and Steadramon, the writer of the ESPGeiger firmware is looking if he can make a drop-in version of his ESPGeiger firmware that can be loaded onto the GK Radmon (and probably GK Radmon Plus too) without the need to modify the counter itself. That would be very cool. It has also spurred on an ESPGeiger

    Modifying the GK Radmon Geiger counter to run ESPGeiger firmware
    Please note that this mod is no longer necessary as the pins can be selected within the ESPGeiger firmware settings. A couple of days ago Steadramon released an updated version of his ESPGeiger firmware, which included a new webhook feature I had been patiently waiting for. This got me playing about with ESPGeiger again and the thought crossed my mind "can I get it to run on my GK Radmon?" I bought my GK Radmon kit about five years back. I didn't like the original firmware much. Not that it was bad, it just didn't suit the way I use my counters. The original firmware was written for very low

    SBM-20 and STS-5 (CTC-5) Sensitivity Comparison
    I wanted to see if there was much difference between the sensitivity between a SBM-20 and STS-5 tubes. For a background test I had an SBM-20 running for a while then swapped it for a STS-5. I think the graph says it all. (Note - there was a discrepancy with the initial background test (below). The test was repeated later and the results are shown towards the end.) I took this a step further and compared the two tubes using 13 different sources. In hindsight I should have tested a J305 at the same time. It took a surprisingly long time, so I might set up some kind of testing jig and program an

    ESP8266 - Wemos D1 Mini - Arduino Code - Bare-bones code, verified working
    ** Note: This is for submission of CPM readings to radmon.org. Here is some Arduino code for the ESP8266 written and tested on a Wemos D1 Mini. This is bare-bones code only. It does only these things: receives pulses on GPIO 13 (physical pin D7 on Wemos D1 Mini), calculates CPM and submits it to Radmon.org (via WiFi) every 60 seconds. It has a little debugging that can print to serial, flashes the internal LED when an interrupt event is detected and I have also added CPM print to serial (much like the NetIO GC-10) that can be used with the Radlog windows logging software - and that is it.
