I am new to seismographs and am planning to build one
with Lehman sensor. I have found a PDF document on PSN
website that talks about constructing Lehman sensor.
Can anyone comment on this document and if it is a
good place to start building one with? I will also
welcome any other advise on how to build a Lehman



Triangle was an improvement over square wheel - 
it eliminated one bump per revolution.
