How to detect trajectory of an object using IMU sensor data?
I'm playing with an idea of putting Arduino microcontroller and IMU sensor inside of a ball in order to measure the trajectory and speed of the ball and also determine when it's not in motion.
Any ...

Calculating Yaw from Relative position of 2 accelerometers
First of all, apologies for the length.
I'm building a drone and have come across the issue of a 6 degree IMU being unable to calculate a sufficiently stable yaw number on it's own. The normal ...

Looks like new IMUs doesn't have integrated magnetometers. How to reorient IMU without magnetometer?
I was searching for some replacement for the old MPU6050, and when I finally thought of ordering ICM-42688-P, I figured out it doesn't have a magnetometer.
Strangely enough, ICM-20948 had a ...
