Summary of BUILDING A KINETIC SAND ART TABLE
This article describes a DIY kinetic sand art table that uses a Cartesian motion platform with a magnet-driven metal sphere to draw patterns in sand. An Arduino and Raspberry Pi control stepper motors to create various designs. Built mostly from low-cost pine with an oak top, it features RGB LEDs around the sand, faux leather under the sand to reduce noise, and configurable lighting effects. The project emphasizes attention to small details that improve the user experience.
Parts used in the Kinetic Sand Art Table:
- Cartesian motion platform
- Magnet
- Metal sphere (ball)
- Craft sand
- Arduino
- Raspberry Pi
- Stepper motors
- Low-cost pine lumber (frame)
- Oak wood (table top)
- RGB LEDs
- Faux leather (under sand layer)
Many of us have marveled at art installations that feature marbles quietly and ceaselessly tracing out beautiful patterns in sand. [DIY Machines] is here to show us that it’s entirely possible to build one yourself at home!
The basic mechanism is simple enough. The table uses a Cartesian motion platform to move a magnet underneath a table. On top of the table, a metal sphere attached to the magnet moves through craft sand to draw attractive patterns. An Arduino and Raspberry Pi work together to command the stepper motors to create various patterns in the sand.
Low-cost pine is used to build most of the table, with oak used for the attractive bare wooden top. RGB LEDs surround the sand surface in order to light the scene, with options for mad disco lighting or simple white light for a subtler look. Other nice touches include sitting the craft sand atop a layer of faux leather, so the ball moving through the sand doesn’t make annoying crunching sounds as the ball moves.
It’s a great build that focuses on the smaller details like noise that can make a big difference to the final experience. We’ve seen similar projects before, too. Video after the break.
