I tried to check the possibilty of the Earth rotation rate measure. I cannibalized old HDD to prepare the rotating table, attached the device to the plate, and performed the series of recordings, turning the device by 180° every 75 seconds, after 10 rotations the results were calculated. 15 series of 10 rotations each were recorded.
Certainly i could catch only horizontal component (vertical is invisible due to linear acceleration effect), i.e. i need to multiply the value by the cos(55.75°). The latitude of my office is 55.75°.
Can you bet the average measured value and STDEV for 15 series of 10 rotations each?
Do you think this research worth writing an artice?
