- “The Safecast bGeigie is an Arduino-based radiation data logger that is being used to generate data for the safecast radiation map. It uses the Freakduino-Chibi board and a customized data logger that interfaces to an International Medcom geiger counter to geotag all the radiation data. Within Safecast, we’re currently trying to have one bGeigie travel to hackerspaces around the world and measure the radiation in those areas.” (quote from freaklabs, see full article at make magazine)

- “ONE of the most unfortunate features of the usual portable Geiger counter is the short life of the expensive high-voltage batteries. These 300-volt units run down very quickly—especially in very hot or humid weather—whether used or not. Here is a portable Geiger counter that operates from only four flashlight cells. A transistor oscillator furnishes high voltage for the G-M tube while a two-stage transistor amplifier drives the headphones.” on emcelettronica.com
