Hello Jim,

Greeting!  I think you can do a whole lot better from and energy point of view.

L15B into SARA SADC20 24 bit digitizer with GPS into a TS-7260 embedded linux single board computer storing data to a flashdrive continuous and by events. To get you data, just change the flashdrive.  The whole thing uses less that 3 watts, you might not need the solar panel.  Just a big battery for a few months.  Who needs all the extra stuff you need to power in a laptop. No sleeping problems, windows problems and many other problems with remote complicated operating systems.

Guys- I need some help on designing a remote seismic system.

Let me know what you think of what I came up with so far.  I can be contacted at email below if you want pictures or more details. 


An affordable remote SDR system (site) using a Notebook & Solar panel for power.


System will record 24/7 for several months in a remote Desert area in AZ using a Solar panel to recharge battery.

The events I collect will be saved in WinSDR, so I can check them occasionally & do a DL.  The system will eventually be used with 110-A/C when it comes on line. 



Using Larry Cochrane’s P/A, Filter, GPS & A/D Box- 8 channels in 1 Box.

Using L15B sensor elements (4.5Hz) in a Borehole package for sensors- 

2 closely spaced BH’s with 3 components each & 2 surface geophones. 

WinSDR on a Notebook.


Power requirements:

LC’s Box takes ~2-3 Watt going directly from the battery.

The Notebook will need a boost from ~12V to ~18, so use a 12V to 18V converter.

            Not sure what power requirements will be?

A 30 W Solar Panel (hope this is adequate) with controller to charge battery (sells for ~~$300).


Comments- Saving Power:

Use XP power saving options-

Disable WiFi

Use Low Power screen-

By using  ~1-2 GB memory stick instead of using the standard HD.

Could replace the standard HD with a 2.5” Flash Drive (a bit Pricey though)?


Questions: ?????????????????

Any other suggestions to lower Power requirements?

Any suggestions for a Notebook that would do the job?

Will the Notebook get too hot, not being in an air conditioned  room?
