   I heard that electronics enthusiasts will make a Geiger counter. Faced with the increasingly complex world environment and electronic waste, I will imitate one. The foreign version seems to be more advanced, with built-in parameter calibration and WIFI remote table lookup. . . Geiger tubes are slightly more expensive (my Geiger tube was bought from a netizen in Shenzhen in Ukraine) and other components are cheap. In particular, the boost circuit cleverly uses the 555 circuit, which greatly reduces the production cost. The original post used the Wemos D1 mini board module and I integrated it directly into a board.

    This Geiger counter software is available in two versions, GC-01 and GC-20. I have packaged GC-01 into an ARDUINO library that can be compiled and uploaded directly with Arduino, or the firmware I compiled can be uploaded directly with the ESP8266 download tool. The GC-20 version has more WIFI functions and needs to be compiled using Microsoft's Visual Studio Code software with built-in platformio IDE, which is more troublesome. However, the original post has detailed teaching materials.

   For the internal structure during production, I used 18650 so the outer shell is a bit thicker.

NE555 boost circuit is so useful

This is the GC-01 version
