Kinetic Art Table
Just finished my latest project which is a kind of kinetic art coffee table. Practically that means a CNC controlled 2-axis plotter that drags a steel ball through a thin sand bed making pattern reminiscent of a Japanese Zen garden. The concept has been around for a while, probably best known from Bruce Shapiro's "Sisyphus" kickstarter project. Design was done in separate 3d-CAD, then 2-d drawings imported to Aspire (Vcarve would have worked as well) for all tool paths, mostly profile, also some pocket and moulding.
To fit my living room furniture, I made the table to match the design of my Ekornes chairs with a ring foot and looped legs: The chair legs are molded beech plywood, which I can not do. So I decided to cut everything from walnut segments that comes somewhat close to the color of the chair's stained beech: All foot/leg segments glued up. I will post separately about my experience with a new type of glue (hybrid silane) that I used successfully here: Sanded and finished. I had not planned for the alignment dowels to be visible in the ring. But I did not pay enough attention that the slope cut of the ring top surface (moulding tool path) would expose the (supposedly blind) dowel holes. Oh well, does not look too bad. More pics to follow.

Re: Kinetic Art Table
I like the effect. To my eye it make it more interesting.I had not planned for the alignment dowels to be visible in the ring

Re: Kinetic Art Table
More pics....
The complete foot assembled with the table baseplate (contains all the electrical/mechanical stuff), the sand bed (walnut frame with 1/8" glass sheet), the tabletop (walnut frame with 1/2" tempered glass sheet) and an enlosure frame (to hide the baseplate and technical things): View of the complete table: Detail view of the top frame joints. I experimented with a kind of frog finger joints (lacking a better term) that allows assembly without frame clamps. Worked pretty well: More pics to follow...

Here some pictures of the guts for the technically inclined folks.
Baseplate with all relevant electronics: Mechanical assembly of the 2-axis plotter complete: LED light strip with diffuser (normally hidden under tabletop frame): Night view:
That's it...
So, what is my next project? Maybe I should finally finish the shop reorganisation....

Re: Kinetic Art Table
Came together BEAUTIFULLY G. !!
ESPECIALLY Like the Foot Assembly and LOVE the face frame "Fingers".
Well Done!!

I've learned my lesson well. You can't please everyone,so you have to please yourself

Re: Kinetic Art Table
Really love this! I've wanted a Sisyphus table ever since I came across them and toyed with the thoughts of a DIY version but figured the software would be the hard part. Did you write your code from scratch? I'd be very interested in getting more details if you decide to make an Instructable or something.
And your woodworking is excellent as well !

The "real" Sisyphus table has polar mechanics, moving the magnet to certain programmed angle/radius positions. This has some advantages but is not compatible with typical motion controllers. Therefore I went for the standard Cartesian x/y concept. The other advantage of x/y is the availability of cheap (I mean really cheap) 3D printer parts like small linear bearings, small steppers and drives, GT2 belts and pulleys and the like. The most expensive part of this project was all the Walnut lumber.
I did not program the controller. I still had a motion controller from Planet-CNC sitting in a drawer that used to run my CNC router until I replaced it with the successor product.
I did write however the software to generate the ball trace patterns and g-code. Actually I modified the versions for making Guilloche patterns and mazes that I am selling normally for CNC maching purposes
If you want to build such a thing, check out the ZEN_XY forum. This is dedicated to building such sand tables with 3d printed parts, Arduino and GRBL/Marlin software. They also have a web based software to generate patterns/gcode.
I did it differently but got some advice there and posted my results.

Re: Kinetic Art Table
Man, that is really cool! Super-fun to see your build progression, too!
Are you going to treat us to a video? Would love to see it in action.

Very elegant. Especially like the corner frog finger joints. I also would love to see a video of this in action. Thanks for sharing all your photos processes and links.
