Automating a Geiger Counter with an ESP8266 or ESP32 #Feather #Arduino #ESP32

Adding an Adafruit Feather Huzzah ESP8266 or ESP32 v2 + a FeatherWing 128×64 OLED to a MightyOhm Gieger Counter to automate data collection: WhyzaGC.

I am always on the lookout for unique and interesting kits to build which led to me discovering the MightyOhm Geiger kit.

While there are a couple of other Geiger kits around, the fact that the MightyOhm was in stock ( rare in these post covid times! ), it included a commonly used detector tube ( for relative data comparisons ), its serial output, along with its steampunk looks, it had me sold.

I initially started with the ESP8266 and then ‘upgraded’ to the ESP32 to take advantage of the dual core as I ran into limitations multitasking on the ESP8266.

As such I would recommend the Feather Huzzah ESP32 v2 over the original ESP8266 version due to both the NeoPixel RGB LED and dual core functionality. That said, if you have a Feather Huzzah ESP8266 already, it will work just fine.

I also discovered Radmon.org which seemed a worthwhile project to contribute data to. It has a very simple and easy registration process…and runs on solar power!
