Hi Jim
I have been thinking of the same for years but not much beyond thinking. I have found several single board computers advertised in circuit cellar or nuts and volts. The acquisition program compatability and timing is a little beyond my for a "from scratch " system. TERN has several boards from 75ma up that run on C programs. There is another company in Circuit Cellar (Technologic systems) which has a SBC that runs at 1/4 watt and runs Linux. MVS has a 386 SBC that is all CMOS and runs at (believe it or not) 0.1 watt. I'm interested in what Angel was saying however I do not understand exactly what components he was describing.
Regards
Barry

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.
System:
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?
