Regarding the magnets - there was a discussion with my extrapolations on how it’s configured. From what I gathered looking at the Morph & multiple overlays, I believe there are only 4 magnets that encode the magnetic ID. One magnet is placed in each “quadrant”, in one of 4 places, with the orientation either North or South.
The key issue though is that they haven’t opened up the Morph firmware & app to allow for custom magnetic IDs. Because of that all we can do is copy magnetic IDs for existing Overlays. If they ever open up a block of IDs for users to customize then they might be more forthcoming with details that either confirm/deny my assumptions. Here’s hoping…
