Hello all

It has been some time since I have send a email to this postlist. But I
have been in school for past few months. Now the school is finished for

I have finished the modifactions to the lehman I did get help with
building last spring. It appears to be working fine. The top of the
frequancy of the sensor is 2,5Hz (lower end somewhere around 0.5Hz or
lower) and I am not sure why that is. I hope it works with teleseismic
event. But only time is going to tell.

Here are the pictures of the sensor and the changes I did do to it.
