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.

Ok this the best comment on my work I got so far, thank you so much! I really appreciate it that there are other people who value the outcome as much as I do.

As you said it is quite silly but I think it represents our surrounding nature and our world so good: as a quite fragile ball floating in space which we have to take good care about :)

Hehe

Hm yeah maybe that would work… I have to think about a bit more…

Also great idea! So cool that you all give so nice suggestions :)

Thanks!

Sadly no, but I try to keep the plants happy as best as I can ^^

Also great idea. My idea right now is an infrared thermometer to measure when the surface is dry and then sprinkle it with water when it’s necessary… but that’s a bit overengineered :P

Ahh thank you!

This makes so happy that you point this out because this is exactly what I was aiming for: while technically impressive I tried to hide any sign of technology, even the cable is sleeved with natural fibers. All things visible are only natural materials.

Ah now I get it, I didn‘t know the term for it.

Aber ja das würde richtig Sinn machen!

Thank you :) Sure, Fediverse all the way :P

I asked it but sadly it didn’t answer and just turned away from me :(

Nice, thanks for referencing Earnshaw’s theorem :)

Sorry but what is a USV? -.-

Yes, needed electricity is a bummer, but if it comforts you it runs only from electricity from my solar panels ;)

That’s true, however it dries up way to fast now. So not much being gained here at all sadly

Yes, for now I spray it two times a day. The moss ball dries up so quickly, of course even more so as it sits freely in the air. So not practical at all, but very nice to look at

Yes, big permanent magnets to push it ip and electro magnets to keep the floating magnet centered

Sadly it cannot be done with just permanent magnets, then you need at least one contact point to stabilize it.

Sure thing :)
