Description
I've recently launched the duneweaver.com website. Check out all of the Dune Weaver tables and add-ons there! (Image above is of the Dune Weaver Pro, not this one, Dune Weaver OG).
We are starting a new Discord channel to help with troubleshooting and feedback. I will prioritize Discord over chat and comment. Please join us here: https://discord.gg/YZ8PTezVHt. If you have trouble with your build, please post in #qna-dune-weaver.
My all new 10 inch tabletop design is now available here: https://makerworld.com/en/models/896314#profileId-854412
If you don't want to glue the tabletop together (it can be a pain to do), I've made another design to use an IKEA tray for the tabletop! Check it out here: https://makerworld.com/en/models/865113#profileId-816175
Update:
2025-01-14: Huge UI update, thanks to Thokoop!
Warning:
I fell in love with the idea of a kinetic sand table a while back. It combines art, engineering, programming, and tinkering perfectly. Unfortunately, most of the open-source versions often require a lot of hardware. There really was not a 3D printing-friendly design out there, so I set out to do it myself and learn how to 3D model in the process.
But first, I must give credit where it is due. I did not come up with this design myself, but was greatly inspired by the work of Newsons Electronics, a fellow Canadian. I took this wood-cutting design and adapted it to be 3D printing friendly. However, I completely rewrote the Arduino code and created a back-end and front-end web interface to control it via a web interface when you connect it to a Raspberry Pi or a computer.
Introducing Dune Weaver, the most 3D-printing-friendly kinetic sand table on the internet. The table is 420mm in diameter and 136mm in height. The device is a motorized sand table that creates stunning, intricate patterns in sand using a steel ball guided by hidden magnets. Powered by an Arduino and a CNC shield, the table’s motors move the ball smoothly across a fine layer of sand, drawing mesmerizing designs. With the Arduino connected to a Raspberry Pi or a computer, you can control the table via a web interface, selecting patterns, uploading custom designs, or previewing the ball’s motion.
There are two motors; one controls the angular movement, and the other controls the radial movement of the ball. Note that with this design, when the angular axis moves, the radial axis also moves along with it mechanically. We have to address this problem in the software: offset the radial axis's movement by how much the angular axis moves.
If you opt not to use a Raspberry Pi or a computer, you are limited to a couple of patterns that can be fitted into the very limited memory of the Arduino. However, if you connect the Arduino to another device, we can now use the Serial connection to send instructions over to the Arduino to be executed, thus removing this limitation.
Both the base and the tabletop are 3D printed. Note that since we have to cut the tabletop into four pieces, there's a fair bit of glueing and sanding involved to make sure that both sides of the tabletop are smooth. If you have access to a wood workshop, I would recommend creating a wooden surface instead.
All in all, I spent about CAD$100-150 to create this table. Not bad, since the cheapest one that you can get out there is about $500 and is half the size of this. I was planning to fit all of the hardware in the base, but I ended putting everything in an IKEA cable management box. The table looks pretty neat on an IKEA KYRRE stool.
I really enjoyed working on this project and finally got to share it with the world! I spent about a week 3D designing the hardware and about a month on the code. I would love to see if you ended up making one. Please join our discord channel if you run into any issue or have a feedback https://discord.gg/YZ8PTezVHt
Enjoy the Dune Weave!
