6 point IMU calibration - How perfect is perfect?
Thank you Garug ... yeah, I was wondering about that foam ... !!! Understood about the various calibrations, but one more question: If, n future, doing temp. calibration, assuming the camera IMU is square to the axes of the gimbal, (which becasue …

Roll Drift from zero to fully canted over time 32bit 3 axis
Ground a soldering tip to needle point, and using reading glasses and magnifying glass, I think I fixed it. I added a dab of epoxy to three sides of connector on each IMU to prevent it from happening again. Had to de-pin the 12c cable end to remov…

Roll Drift from zero to fully canted over time 32bit 3 axis
Further update: Don't judge me too harshly - I've been gently removing and reassembling small electronics for years. The JST connector on the camera IMU came off with only the tiniest bit of pressure as I was trying to remove the 12c con…

Roll Drift from zero to fully canted over time 32bit 3 axis
Question: One thing I have noticed during all stages of this experiment is that the YAW axis responds to roll deflection. Note: The SteadyMaker Tank is sitting on its integrated stand, so the handles are free to rotate in the air. So when I woul…

Erasing EEPROM did not work out so well ... I realized I should have taken notes, so I reloaded it, and it was largely different than before. Interesting. Back to square 1.

Roll Drift from zero to fully canted over time 32bit 3 axis
Hmmm ... would that possibly be the outputs not responding to follow as well? But they do operate properly with regard to the joystick, I think ... pushing up makes camera tilt down, pushing down makes camera tilt up, (although sometimes it seems t…

Roll Drift from zero to fully canted over time 32bit 3 axis
Thank you Garug, It's a fresh day so a fresh start. After what I found last night I'm 96% convinced it is imperfect Acc calibration and very sensitive to temperature. Understood about the IMU cal costs ... I thought the data stored in t…

Roll Drift from zero to fully canted over time 32bit 3 axis
Update: Temperature calibration values now writing at 27 degrees difference. This is too much, so I will ahve to start over when it gets colder outside again. Question: Why are these not calibrated from factory, so that, say, -50 to +150 degrees…

Roll Drift from zero to fully canted over time 32bit 3 axis
Thanks for trying to help .. I feel like crying I'm so frustrated ... hours of work today and no good. According to manual temp compensation needs 10 degrees difference ... I had 17, acclimated for well over an hour....it would just not regist…

Roll Drift from zero to fully canted over time 32bit 3 axis
Thanks ... already checked. Even with joystick disabled, it is a problem with temperature. I cannot go through a 20 minute Acc. calibration every time I move ((In Alaska, temperature changes a lot .. very cold, medium cold, not cold, and hot) Loo…

Roll loses horizontal angle randomly
I am reading with interest after fighting with temp. Acc. cal. So does it work, or does it not? If it does not work, why is it there? Roll is very important .. resolution loss due to correcting in software is bad for my mood.

Yaw problem while tilting
I would like to understand this as well. axis order?

Roll Drift from zero to fully canted over time 32bit 3 axis
Also, I wanted to mention that performing a gyro cal manually (yes, it is very still!) does no good once the roll error starts .. it just accumulates and gets worse until Acc. cal. I have the unit outside in my cold unheated shop now ... in an hour…

Roll Drift from zero to fully canted over time 32bit 3 axis
Thanks for your response. The calibration I am talking about that fixes the issue is the accelerometer cal. When it starts drifting, the ACC cal is the only thing that fixes it. I have the checkbox for the Gyro cal OFF at startup. I am going…
