After testing 7 #LilyGO #TBeamSupreme units, one thing is clear:
👉 Magnetometer calibration is not transferable between devices.
Even in similar environments, raw readings varied dramatically between units. Proper calibration isn’t optional—it’s per-device.
I also looked at how #Meshtastic handles the onboard #QMC6310… and it essentially doesn’t (no heading, no calibration).

🚫 So, you're all set to become the next #magnetometer maestro with a couple of spice jars? Hold that thought, because the only thing you're building today is a 403 error page! 🤦♂️🔥 Maybe try #paprika next time? 🌶️

I'm building a lightweight, low power, waterproof, #multisensor, configurable #magnetometer for #geophysics and #geophysical site investigation. Logging with low power Linux SBC (Pi/Pocketbeagle). Interested in helping fund the project for discount prototypes? DM me. 10,000-250,000 nanoTesla sensitivity range less than 1kilo per meter of array. Maybe less. Easily flown with a drone, your choice of GPS.

Schon seit Stunden steht unser #Magnetometer nicht mehr still, aber die Wolkendecke über Heidelberg bleibt geschlossen und es regnet immer mal wieder. Webcambilder bestätigen hingegen: rotes #Polarlicht bis in die Alpen. Also nix wie raus mit euch, wir wollen eure Bilder sehen!

"Juice’s first taste of science from space"
"ESA’s Jupiter Icy Moons Explorer, Juice, has recorded magnetic field data as its 10.6 m-long magnetometer boom deployed. .. The Juice magnetometer boom (J-MAG) was deployed on 21 April, when Juice was about 1.7 million km from Earth."
