Assuming that Y and Z are perpendicular to the Earth's surface, they report "g" to be 2060 +/-2 and 2058 +/-1 respectively, while X reports 2160 +/- 1, for a 5% difference.


How on earth can two mutually perpendicular axes be perpendicular to earth's surface? I am now getting blown away to bits.

One at a time, obviously. If this is too difficult for you, choose another hobby.

I'm out.

Ok, so, seems my local walk-in supplier has stock of the gy-521 so if I get one today, that's the long weekend sorted ;)

(Wondering why their Keyes version is almost 3x as expensive as the EIE one... maybe I'll find out when the cheap one doesn't work.....)
