It used also accellerometer from analog. Why did it use the AD chip ? Like I said, not well suited to long period seismic detection. The Lehmann is really easy to build. There was an optical force feedback seismometer featured in an old "amateur scientist" column in Scientific American 10 years or so ago. Steve Hai With accellerometer the system will be below 100US$ in total. Geophone rather expensive than accellerometer. Regards Jeckson Ben |
