I have a 7th grade student who wants to build a seismometer for a science
fair display. He has plans for a broadband seismometer using stereo speaker
parts for the feedback transducer. Does anyone have any building plans for
a seismograph? The ones he has found are "too simple". Any ideas would be
appreciated.
