An update on the build status of the magnetometer. The board has been tested for correct voltages and other parameters. The three sensors have been wired with filter capacitors and connected for some software testing as well. They have not been placed in any permanent housing, and we are investigating best practices for that. We anticipate installation in the fall term once students are back on campus and we regroup. Some images:
Space weather has long been an interest of mine, and of many of the students passing through my astronomy courses. The interaction of the Sun, it solar wind and our Earth’s magnetic field are just fascinating. Living in high latitudes, we sometimes are given the pleasure of seeing some aurora. In collaboration with the University of New Hampshire, we have taken on the building of a 3 axis fluxgate magnetometer. The unit is from a kit which you can check out here at the SAM-III Magnetometer page. If you are not quite so keen on soldering small components (only a few are surface mount), then you can also order a pre-built one…. but it costs more.
Here is our progress to date in photos.
