BIG thanks to Chankly for doing all the heavy lifting in this forum post.

I was able to get my Mightyohm Geiger counter to send serial data to my Raspberry Pi and post history graphs of radiation measurements via a web server. The Raspberry Pi can power the Geiger counter if you remove the batteries. Here are the steps I took:
1. Disable the Raspberry serial port to prevent Linux from using it as a console:
sudo raspi-config
2. Connect the Geiger counter to the Raspberry Pi (Remove Geiger Counter batteries before connecting power)
Mightyohm Geiger counter ----------------Raspberry Pi
Serial---pin 1 black triangle----------------Pin 6 Ground
----------pin 4--------------------------------Pin 8 Transmit Data
----------pin 5--------------------------------Pin 10 Receive Data
Pulse----pin 1 black triangle---------------Pin 14 Ground
----------pin 3--------------------------------Pin 1 3.3v
3. Test that the Raspberry Pi is receiving data from the Geiger Counter:
sudo apt-get install minicom
minicom -b 9600 -o -D /dev/ttyAMA0
4. Read Chankly's entire thread, download the archive and follow the instructions for setting up everything. Remember your Geiger counter is on ttyAMA0
