I'm looking for a way of measuring angular velocity in a spinning object at high speeds - up to 25,000 degrees per second. There's ridiculously expensive gyros in the market that can do this, but I'm hoping to find a way of using off the shelf, affordable sensors to do this.
2x thoughts come to mind
1 - using a magnetometer recording at a high frequency to record each time the sensor passes magnetic north. 2 - Using accelerometers to measure the centrifugal force of the spinning object.
I researched the concept of using 2x accelerometers which appears to for slower movements (less than 360dps).
I'm wondering if anyone else has been playing around with something similar or can point me in the right direction as to how we might be able to capture this data.
