| Ball not rolling smooth | 14 Relevance | 5 years ago | jay14837 | Table Usage | |
| The ball I’m using on my metal side table is Rolling vary choppy. Not a smooth roll like we see in the Sisyphus videos. Does anyone else has this issue. My first thought WAs to much sand, then I took a bunch out and did an erase pattern to spread the sand. Is the sand compacted now or something. | |||||
| RE: Maintenance track wish | 10 Relevance | 5 years ago | Bruce | Table Usage | |
| As several other users have noted, simple physics makes it inevitable that sand will accumulate at Rho 1.0. I take issue with a couple parts of this statement. First is the term "simple," and second, "accumulate". The latter is a minor quibble: it's obvious that if the ball's reach is confined to a perimeter, this will result in what I call the "terminal berm" (others have used "windrow"). This ridge does build up over time, but only to a point, which is self-limited by the angle of repose for the silica we use. But my real disagreement is with using "simple" to describe the physics behind devising strategic plowing strategies using a Rolling sphere on / through granular matter. It "seems" like it should be easy to create Sisyphus paths that move sand in a desired direction. Most people (including me) intuit that the erase pattern should move sand out when running from Rho 0 to 1, and in when running from 1 to 0. But this is greatly dependent on the tightness of the spiral (how close successive passes are). My empiric experience suggests simple Archimedes spirals have very little net effect on overall sand distribution. I tried several times over the past 20 years to devise an efficient strategy for "plowing" routines, and never succeeded. I'm not saying it is impossible - I'm pretty sure it is. But it's not easy, at least for me. However, dumb luck + paying attention, led to noting that tracks that repeatedly move in and out while precessing around the field, when run from Rho 1 to 0, are very efficient at plowing in toward the center. Case in point: Create a playlist composed of erase then apache. Play it sequentially with repeat on, overnight. And yes, during our failed struggle to improve 2-ball reliability, I made several attempts at devising a plow-in track that started in >1 territory, hoping to break up and move the terminal berm into <1 territory - with extremely little success. Growing up and living in Minnesota, I (along with all my fellow northerners) am very familiar with plows. My take-home from this exercise: Rolling spheres make piss poor plows. 🙂 (ps - would love to be proven wrong) | |||||
| RE: Impact of relative ball size? | 10 Relevance | 6 years ago | Bruce | Table Customization | |
| ... start to stick to one another due to van der WAals forces. This is why powders don't behave exactly like sands do. I have used pure baking soda - it works, and produces great detail - but just doesn't look as nice (IMO). This particle size boundary limits smooth Rolling of smaller balls (ball:particle size ratio is too low - the ball gets "stuck" and deflected by the particles). Again, it's not a functional limitation - I have used ~1/8" diam. BB's, and they "work" just fine - but they move jerkily. If your goal is to to a picture of a completed track that ... | |||||
| RE: Ball not rolling smooth | 10 Relevance | 5 years ago | Bruce | Table Usage | |
| The ball's movement normally has a small amount of "jiggle" due to the fact that the sand particle size is not negligible compared to the ball size, and the ball is perturbed slightly as it rolls over the particles. However, if you've experienced a change in the WAy it's moving, please take a video and send it to our support staff, who will troubleshoot the issue with you. | |||||

| RE: One vs Two balls on 3' wooden table | 5 Relevance | 8 years ago | Bruce | Table Usage | |
| @heropup- No apologies accepted (since never needed :). Off topic is OK. There's no theoretical reason 2-ball can't work for any version of Sisyphus. But implementation and support are the sticking points. That being said, we will be Rolling this out soon. Your "primitive" program is spot on: (1-rho) and (theta -Pi). I call this "Tantalus mode" (sticking with the wickedly cruel Greek punishment theme). It only applies when both balls are attached. Don't have a name yet for if only the tail ball is running. | |||||

I have been so happy with the elegant simplicity of the table I am not sure about doing the upgrade on it. I might get one of the new mini tables. I love showing the table to friends and family. Most interesting item in our home. | |||||

If you run a firmware update, it should restore the latest versions of the light code. I would suggest deleting the lights folder from your Content backup. Official backup/restore of content is on our short list of future updates. Matt | |||||

I used a 6mm mirror plate as the sand support surface and used fine baking soda as sand but I have 1. noise when the ball (16mm) is Rolling and 2. the ball movement is not as smooth as the ones in the Sisyphus Table Trailers. In search for a solution I found this forum and this post. So I WAnt to kindly ask if it is possible for you to tell me what is used as sand support surface and what type of sand (exact size, shape ... | |||||
| dampening noise from table | 5 Relevance | 7 years ago | davidp | Community Tracks | |
| My daughter figured out a WAy to make my table much quieter. She first noticed that the sisbot (if that's the right term) made no noise at all when disconnected from the table. However, she could feel it vibrating. So she figured the problem WAs the transference of that vibration to the table. The table itself then acts like a drum and amplifies the sound. Next, she cut eight octagonal rubber WAshers out of a wide rubber band. She added two to each of the four screw-fasteners (also, pictured below). The octagonal shape made it easier to position the w ... | |||||
| A Question of Noise | 3 Relevance | 5 years ago | UK Guy | Table Usage | |
| ... would quieten down but this has not been the case. I had read somewhere in this forum mention of a 'satisfying crunch' sound but this is not what I am referring to. The noise I'm concerned about is a 'grinding' type sound that is especially loud when the ball is running in a more direct line from the 0-1 axis or 1-0. I have tried running the mini with the ball(s) removed altogether and the 'grinding' sound is just as loud so it's nothing to do with the ball movement itself. When a track is in pause mode there is no sound whatsoever and the speed setting is ... | |||||

| Table arrived via FedEx. The driver literally rolled the box onto the porch and up to the Door! Lord only knows how this poor table suffered on the trip! When I ran the erase program the table ran fine until it got to the outer reaches and then the ball stopped and the table began a loud chattering. It sounded like it WAs hanging up on something. Found that one of the supports for the main plate WAs bent. Bent it downward a few mm and the table has run fine for an erase cycle and now a drawing. Just an FYI. | |||||
| RE: Remote control by LaMetric Time, IFTTT, etc.? | 2 Relevance | 4 years ago | remy | Other Development | |
| Today I decide to give it another go (annoyed Google home/assistant integration stopped working). I solved it via my Samsung Smartthings hub. I've created a smart app in Smartthings that takes the input of a switch to determine if the Sisyphus need to be on or off (sleep or not). I access the table based on that switch and created a virtual switch in Smartthings that I name Sisyphus. The smart app accesses the Sisyphus table and mimics what the app sends to the table (monitor your network traffic 😉 ). Due to Smartthings being integrated to Google home/ assistant I now have a device called Sisyphus that I can also use in routines of both Smartthings and Google Home/Assistant + voice etc. Works like a charm, out the Door with IFTTT. | |||||

| ... talk about polar vs SCARA design. Also check out "Zen Table" by Simon Hallam, he WAs one of the first ones to commercialize the concept a few years before Sisyphus, but he used a cartesian design. We believe SCARA is superior to both cartesian and polar and a much more elegant solution that opens the Door to very unique possibilities, like our Stelle design, which would be impossible with either one of the other mechanism types. This WAs one of the responses to the comments in the campaign, and I found it a bit disingenuous, to say the least, because the ... | |||||
