"You talked, we listened, and we’ve revised our Geiger Counter board to address some of the most pressing concerns. This version features an improved voltage regulation circuit for the Geiger tube which has a much cleaner output. We’ve also modified the signal capture portion of the board so that it reads active high, allowing for more dependable counts that are less susceptible to fouling due to line capacitance. The new signal capture circuit also pushes the CPM limit to 100Hz!...

"Need to test for nuclear fallout? Geiger tubes are the sensing elements of Geiger counters, which are used to measure ionizing radiation. This tube is made of a thin-walled stainless steel and is filled with a mixture of Neon and Halogen gases at low-pressure. You’ll need a large voltage to get the Geiger tube to going - 325VDC minimum, 500VDC recommended. If ionizing radiation passes through the tube, short pulses of current will flow from the negative electrode to the positive...
