Sand Table - Golden Ratio Spiral

This pattern uses the "Golden Angle" (137.5°) often found in nature, such as in the arrangement of seeds in a sunflower.

I would go crazy hearing that sound coming from my table all day long.

[@jayjb833]

The scratching at the table would drive me insane

It's ASMR

@@_kimmochi_.6090 Maybe if the grinding was smooth and consistent, the shuddering is what drives me nuts.

[@OzDeaDMeaT]

holy crap that thing is loud

[@aftabkhann2314]

I actually own one,and the sound depends on the speed you set the ball in, I usually set quiet slow, so there will be no sound

Amazing (and esoteric as well 😅)

哈哈 ! 原來是這樣來的,心算能力強的可以算算到底它繞了幾次(可能要參考最後在中心的動態!？)😅 !

did anyone ever get one?

[@ramupittala510]

One Olympiad question on this.

[@71stang]

Why is it so loud dude?

[@markrolandmakes]

First of all, apparently I don't get comment notifications so I'm just stumbling across these.
I agree that it's definitely louder than you'd want something like this to be. This is a custom build and not the popular Sisyphus table, which I also own, and is nearly silent, so props to them on that!
To address the noise there are a few things to know: 1) It is uncovered. Covering it with glass makes it quieter, especially in regard to the scratching. 2) There is fabric underneath the sand, which does help, but other materials could definitely be explored. 3) Different sand or other substrates could be explored 4) The stepper motors can be made quieter with other drivers or code, but this isn't something I've explored.
I hope that information helps anyone else attempting something similar.

Put a sponge under the ball, it should move along smoother

Sound is annoying
