This is our first prototype for the flight computer that was supposed to be used in the first test flight that was canceled.
Here you can see the pressure sensor (left-most component), IMU (the component near the center), and SD card reader (right most component)
The inertial measurement unit (IMU) is responsible for measuring the rotation and acceleration of the rocket. We need to ensure that it records information accurately in real-time. To test it we spun the test stand on a lathe at a known RPM (verified by both the lathe's RPM counter and by using a phone flashlight flashing at a set frequency). So far, this has been the only sensor we've tested.
The above lathe test-bench gave us meaningful test data, in this example we spun the lathe at 100 RPM, and the data's average is 100 RPM. This is great, but we need accurate live data. So we need to implement filtering to smooth over some of the peaks and valleys.
