Thank you for the kind words..... Could you be more specific, what details did you want? My circuit is built around a 555 timer driving a step-up transformer capable of producing the high voltage my Geiger-Muller required, the rest of the circuit is for driving the sounder/clicker. I don't share my circuits, but here is one that is close....Wow! Very nice - I'm deeply impressed.
Would you mind giving some details, how you built the Geiger Counter?
