Hello Mr. Frímann;

NOT SURE, After thinking since 1994, BUT;
I would like to build something like I saw
At ASU which could recreate three dimensions from only two
sensors that were like inverted pendulums placed 90 degrees
from each other at an agle of 30 to 45 degrees.
But i would need a special A/D converter that would digitize
two discrete signals simultaneously in synchrony, and stuff I just dont have.
When At 45 degrees the signal is split by trig into
vert and N/S or Vert and E/W you need TRIG
to recreate the original signals but I do not care about
the three seperate whatevers. Only first time of arrival
and S-P times and Possibly surface waves at 20 seconds.

If I could build ONLY a single sensor,  sensitive to motion
no matter what the direction. Thats what I , as an Amateur,
really want. I have thought capacitive with a sphere
inside a sphere if at all possible ???

"Please excuse my love of fun and games"

Thanks For your response.

Best regards,
geoff

p.s.  What happend to Chris ?
Hes like the only Instrumentation Engineer type in PSN that i know of.
Possibly Larry but not sure, Larry might br a businessman instead of
Engineer.
In anything Amateur Anyone might be anything at all.
A wonderful place for Agents of all kind.
I often think of those Russian and Chinese folks who
are not really Amateur due to the fact their government
pays their way through whatever and trains them too
at government expense where in the usa they train themselves ?
In the USA we ,with an encyclopedia, must compete against people in other countries
who have the equivelent of a PHD.
Here, few REAL scientists/engineers/technologist/technicians will get involved
Freely On the Internet
due to the fact that their employers throw the fear of God into their
souls about security breaches and patents and stuff like that.
The only reason I have no fear is because they have already ruined me
for anything at all with the mental health poisons and psycho labels. [ no kidding ]

Hi Geoff,

The fossil is a early Cambrian I think. It might be some type of
Arthropod. What species I do not know.

More information.

http://en.wikipedia.org/wiki/Arthropod

http://en.wikipedia.org/wiki/Cambrian

Can you tell me how your seismomter is going to work.

Regards,
Jón Frímann.
