Greetings, I am working on setting up a PSN seismic station here in the santa cruz mountains of northern california. It should be interesting because I am about one mile from the san adreas fault line, just 3 miles from the epicenter of the 89 loma prieta quake. Larry Cochrane is putting together the interface hardware for me, including a 3 channel amp/filter board, the SG electronics board, radio telemetry board, GPS timing and A/D converter. The problem I have is locating sensors. My initial interest is for local event monitoring, so geophones are probably how I will get started. But I am also interested in setting up other sensors like the lehman and SG types. I am wondering if anyone out there knows of any sources for sensors, either geophones, lehman, or shakleford-gunderson style sensors. If you have any of these to sell, or know someone who does, please let me know. I am also wondering if anyone out there would be willing to build me the lehman or SG type sensors, let me know. BTW I have some live weather data from my location posted here: http://sensorium.los-gatos.net/ You can get a weather station from dallas semiconductor for $80 that includes temperature, wind speed, and wind direction. For another $50 you can add a rain guage. They also provide free source code for these devices. See http://www.ibutton.com/weather/index.html. Here are some other interesting weather related sensors: http://www.ibutton.com/ibuttons/thermochron.html http://www.pointsix.com/products/index.htm#1wireprobes http://www.texas-weather.com Thanks, Doug _____________________________________________________________________ Public Seismic Network Mailing List (PSN-L)
