Hi

John has kindly posted my attempt at a 'mini horizontal' seismograph, if you
are interested please go to:

                     http://jclahr.com/science/psn/rogers/

I would be grateful for an comments or improvements you may think I might
incorporate in the unit, especially in the area of feed back to the light
source.

Regards
