As i mentioned in previous log entry I tried to mount the magnetometer close to the anemoscope. This idea turned out to be wrong as the anemoscope has a megnt built-in.

I moved the magnetometer further by designing and printing 15 centimeter long offsetting element.

After calibration the compass works fine :)

I'd also like to mention that current software (embedded and PC app) is available at GitHub.
