About: I am a researcher working on development of optical atomic clocks. Electronics is my hobby since childhood when my uncle was bringing me old phones to play and take apart.

Instructable describes a Geiger counter that is connected to internet so that also other people can monitor ambient radiation situation.

    Dear Sir.

    I saw the circuit diagram of the Geiger counter in the attached PDF, but there is no information about the used transistors... I did not found the BF546 datasheet. Is it wright ? And the other 2 to drive the speaker?

    About the secondary of the transformer: How much turns did you used?

    Thank you very much, Mauricio Girardi.

    Dear Sir,

    I am relatively new to Arduino and C programming. Can you please tell me if is the counter reset by program or manually?

    Thank you for potential answer.

    Dear Jani_Slegr,
    thank you for interest about Geiger conuter.
    In the program I wrote the counter is just counting pulses and the number is increasing. This large number is read out by computer once a minute via USB-serial Arduino interface. Pulses per minute are calculated on the computer. Computer just compares the current value with the value that was one minute ago.
    Wish you a Happy New Year!
