Sisyphus, a company wholly separate from Sörensen, does indeed make artful tables that feature metal balls rolling out patterns in sand endlessly.

As a musical instrument plays songs, Sisyphus plays paths.”īruce’s work is featured in permanent installations in Switzerland, Germany and Australia. “Watching Sisyphus evokes a meditative feeling. Over time I have come to view Sisyphus as more than a kinetic art piece: it is an instrument. “In my art, Sisyphus is a kinetic sculpture that rolls a ball through sand, forever creating and erasing beautiful patterns,” says Bruce. The name Sisyphus is based on Greek mythology in which Sisyphus was condemned to roll a boulder up a mountain for all time. I haven’t looked at Sisyphus mechanics much, but I think that’s what they use as well.WORDS Mary Garner VIDEO via Bruce Shapiro on Vimeoįormer doctor Bruce Shapiro, who has been working with motion control as a medium for 25 years, has created his first kinetic art sculpture for the home – and it’s Kickstarter’s most successfully funded art campaign to date, having raised $1 924 018. I think the Rack and Pinion mechanics are really what you’ll want for a large table. It’s really well optimized for the small size that I have, but you might have noticeable resolution loss at your table size. You wouldn’t want to use those mechanics for a large table either, because the resolution decreases as the radius gets larger. Here is my table drawing the hosta pattern from that subreddit Micro SD Card Support Rob and I worked hard on this, and in the end the only thing we could get to actually work was the Adalogger feather wing with SD Card in it. I’m actually turning that into a product seen here, so the codebase and mechanics aren’t particularly friendly to work with. The sisyphus subreddit is a great place to find custom files. There’s a lot more that goes into the double gear design, and that’s running on custom firmware. I’m pretty sure I used a gear generator in Fusion 360 to make the gears, because no one has the time to be designing spur and pinion gears by scratch. It wouldn’t help you too much anyways because the gears weren’t parametrically designed, so you wouldn’t have been able to scale them up. If I had the files I would share them, but unfortunately that rack pinion design has disappeared into the ether on me. The only solution is to decrease friction as much as you can and strengthen the arms. Sisyphish is like the Sisyphus Table if it were a fish tank. My design would have the same sorts of issues you’re seeing on a very large table just because you’re dealing with such long arms. Sisyphish was inspired by the Sisyphus Kinetic Art table by Bruce Shapiro. ![]() PTFE will technically work better, but it will also wear out faster. It is incredibly captivating to be beside this simple DIY wooden table as the steel ball magically carves out an endless and ever changing series of beautiful geometric patterns in the sand. I prefer UHMW for this because it has a pretty low friction coefficient and good wear characteristics. A stronger magnet linearly adds force to the system, so you really want to make this as small as you can.Īdd some sort of low friction tape to the top of the magnet where it contacts the underside of the sand reservoir. Make the magnet as small as you can without affecting ball motion. Looking through this design quickly, it looks like there are some very long moment arms involved, and I’m not surprised that you’re running into issues if you’re making the arms out of plastic. The kinematic conversions necessary to make it work happened at the Gcode level rather than the embedded firmware level. The software was unmodified Marlin I believe.
