Here is a new picture of the seismomter with 1kg mass. This build of the
lehman type seismoeter is deeply flawed and is going to get scrapped in
two weeks time or at last repared. But there are better chances that I
am going to build a new one with a help.
I don't know what the natrual period of this seismometer is, but my
guess is that it is somewhere around 1 or 2Hz. But I do see cultural
noise, but it is not as hig as on my geophone.
