I ran one pattern at 100 mm/sec and at 500 mm/sec (acceleration at a constant 10k mm/sec^2) and took some pictures so you can see what speed does to the resulting pattern. As I shot these images, the sand was a few mm deeper along the top edge of the images than along the bottom edge.

100 mm/sec

500 mm/sec

That is not quite fair. Not only do you have one of the coolest sandtablesā€¦ you also got a video with a cat and the sandtable. Combo cannot be beaten :+1:

Hey man, just wanted to give you props on the Hackaday write-up they did for this. :+1:

Thanks! Itā€™s not my first HAD write-up, but itā€™s one of the few that isnā€™t a failed project.

Awesome! Iā€™ve never seen a Sandstorm generator before.
