    UW Nanotechnology Grad School Prospects

    Hi all, The first few paragraphs are background about me. If you don’t want to read this, please skip it and answer my questions at the bottom. I’m a nanotechnology engineering student at the University of Waterloo. Over the past two years of my studies (I’ve finished 2B,) I’ve found that...

    Calibration of a 3-Axis Accelerometer for fixing effect of gravity

    Hey, Okay, they are very far off. I have attached the excel sheet containing the rotation matrices and the final calibrated answers. P1:R3 (yellow cells) contain the Rz matrix since (x-tilt is the rotation about the z-axis). T1:V3 (green cells) contain the Rx matrix (y-tilt is the rotation...

    Calibration of a 3-Axis Accelerometer for fixing effect of gravity

    Thank you for your response. Yes, I realized the solution couldn't be that simple. I think the solution can be given using a rotation matrix. However, this is not my area of expertise. I was wondering if anyone here could suggest a possible solution. So far, what I'm thinking is, I should find...

    Calibration of a 3-Axis Accelerometer for fixing effect of gravity

    Hi all, I've been trying to develop this excel macro for mapping out a train track and locating kinks. It's been going well so far except that when the accelerometer is not exactly level with the ground, the acceleration due to gravity (9.8 m/s^2) is not only effective in the z-direction...
