bill take in my mind some elucubration about the dynamic calibration.
as stated before, you can split the process of dyna calibration in two parts, one for the gyo/acc and one for mag.
the gyo/acc can be accomplished by only turning the board itself rather than the whole multi.
so i start thinking about making some sort of gimbal for the board, driven by two 360 servo on tilt and roll axes.
maybe an arduino with the right library for the servo where you can program the movements as the calibso dance and then they will be reproduced with all the smoothness and precision possible.
i just started coding something and today i wish to finish the frame of the gimbal.
just one thing.... the 360 continous movements is useful for the gyro / acc ? i think the contiunous turning movement is to be intended for mag purpose. am i right ?
Brainstorming time
after some testing i'll certanly post my results.
