I'm not  handy at thinking electrical circuits through. [D)] I am looking for the diagram for making a simple buzzer box to warn of short circuits (reversed drop feeders etc.) while working away under the benchwork. I found this old thread on the topic but the photos have been removed. http://cs.trains.com/trccs/forums/t/140951.aspx?PageIndex=2 Can anyone post me a simple circuit?  I simply want to use a piezo buzzer and 9 V battery I have on hand.  I don't need any other functions on the circuit.....LEDs etc. etc. Thanks to anyone with a diag. to post or written instructions etc.
