      damn the base is almost 50 degrees? It looks way more complicated than I was expecting too. How does it stay upright?

        I didn’t thought it would get so hot, but the moss ball has quite some weight to it which needs more power to keep it centered. It weighs ~500g when watered.

        The purpose of the electromagnets in the base is exactly to keep the floating magnet at the bottom of the moss ball centered. There are hall effect sensors measuring indirectly the position of the floating magnet and correct the faintest misalignment. The more mass the more power is needed, that’s why it gets so hot.
