Has anyone used the JoyWarrior to detect distant thunder?

While mounting a JoyWarrior unit in the centre of a window is probably unconventional, it would amplify low frequency sound waves, and could be used to detect infrasonic signals from distant thunderstorms and at higher frequencies at levels ...

:-)

Makes sense. Is there a way to offset the traces in seismograph 1.0.exe to allow the signal to show clearly, rather than only show as faint wiggles on an otherwise flat line?

OK, when I run calibrate.exe, the values (uncalibrated) are X:~115, Y: ~-90, Z: ~3990

When I run Tilt.exe, the values are: X: ~8300, Y: ~8100; Z: ~12190

When I run Seismograph 1.0.exe the Min/Max values are: X: 0-124, Y: -102-0, Z: 0-4009

When I run the display process at 2G and 10Hz, the X and Y ...

I'll check when I get home, shortly.

Thanks. I finally found the scaling control. The DC offset for Z is quite large, so I probably need to calibrate the sensor. However, will this cause problems when running QCNLive?

Fixed, I think. There was a blank drop down selector, with no title. Hidden in the drop down menu was the device number, which I missed first time around. The program works when I select the number.

However, the traces show only very small variations or are completely flat, for any G, Hz setting ...

Has anyone got this working on Windows (XP)? I can get the other JoyWarrior software to work (Tilt.exe and calibration.exe) but not Seismograph 1.0.exe

Not sure if I'm missing something.
