This chart auto-calibrates to the response of each magnetic sensor over time. As it does, accuracy should improve.
Welcome to my spot on the internet. This is a work in progress, always changing and being tinkered with. Them being neglected, but never quite forgotten
At the moment this is a place where I experiment with things I'm learning about computers and I.T. The biggest change there has been converting the site to a more dynamic format.
This is also a place where I can enthuse about my hobby of astronomy. I have something of an old world approach to this, as evidenced by my love of visual observing instead of computerised imaging. Sadly it's a hobby that I don't always get a lot of time to pursue, but I'm trying to improve on that!
