I own several geiger counters. All of them miss a datalogger and a long lasting (rechargeable) battery. They can not be re-programmed for different tubes of for calibration and so on. That is why I have decided to build my own. <\/p>\n\n\n\n

The time elapsed from the start of the project to the current state is about two and a half years. I don’t do this professionally, this is just a hobby project. <\/p>\n\n\n\n

Before starting, here is a list of the features of my homemade geiger counter:<\/p>\n\n\n\n

measures:
– Doserate (\u00b5Sv\/h)
– accumulated dose (\u00b5Sv)
– long term mean doserate (\u00b5Sv\/h)
– Counts per second (CPS)
– Battery voltage (V)<\/p>\n\n\n\n

other features:
– Alarm when doserate is higher than a set threshold
– Graphical diagram of doserate over time
– Datalogger to send gathered data to a computer via USB
– Different display pages with multiple purposes
– Settings menu with adjustable variables
– Updates via USB (Arduino IDE or “RD Suite”) (RD-Suite is not finished yet)
– Display backlight
– Piezo buzzer to make audible clicks if wanted
– low battery alarm
– Very efficient high voltage circuitry
– Battery life of 50 to 70 days when always on and measuring!<\/strong><\/p>\n\n\n\n

adjustable variables (in settings menu):
– Alarm treshold (\u00b5Sv\/h)
– single measure duration (s)
– Light (on\/off)
– Sound (on\/off)<\/p>\n\n\n\n

In the YouTube Video below you can see the assembly.<\/p>\n\n\n\n
