  • While trying to get sane heading readings I found out that the sensors need to be calibrated or else their output will yield very non-linear readings. Here is the process/software I found: http://diydrones.com/profiles/blogs/advanced-hard-and-soft-iron-magnetometer-calibration-for-dummies. Basically, you map the extremes in all orientations and the software creates values to “center” your readings. It makes perfect sense when you open MagViewer and see the scatter plot of the data!

No public wish lists :(
