Hi Ed,


At dataq.com you will find an AD that can translate from analog to serial
for your computer's

serial port.  You can record with the Dataq software, or with the
$150 12-bit DI154RS unit you 

can record with Alan Jones' free AmaSeis program.  I don't know if
the $25 10-bit DI194RS unit

will work with AmaSeis, but I plan to test this within a month or
two.


You will still need to amplify and filter the output of your
Lehman.


For top of the line equipment, AD, and software, check out Larry's
site.  It's a bit more

expensive but has many, many added features.

Good luck with your recording.

     I am interested in taking my homemade Lehman
Seismograph and feeding it into my computer to look at the data online
and to store it for later review. I am looking for a simple system to do
this. Can you guide me a little bit? Can I use my sound card as an AD
converter? Is there a simple program on the web that well let me see it
ONLINE and also STORE it? Thanks a lot. Ed.
