The logger was put on the dashboard of my van in an attempt to detect pot holes.

GPS logging was pretty good and after messing about with some basic sample length = 60 filters, I got some coherent results for the IMU. Potholes should have been seen on the Y axis in the last two 'hillocks' of speed, but nothing was seen !! Maybe a better IMU is required with less noise and more G-Force capability?
