Geiger Counter Kit
Its a geiger counter!
The project is complete! After two weekends of toil, I have managed to solder with adequate proficiency. Kudos to Brandon, Dave, and Kevin who all helped when I had questions about what various electronic components did.
After building the kit, I took it to Japan and tested it out. Of the places I visited, there was no detectable increase in radiation, however, on the flight over one could easily tell a difference in cosmic radiation due to the altitude at which I was traveling.
