Has that been implemented and documented somewhere? Are the pattern files interchangeable between the two designs? Are they essentially equivalent? I haven’t found anything that compares the two methods, only that the corexy system is designed the way it is. Again, for occassional home use, are the servos necessary? I’m confused by the crossed belt paths in the corexy configuration versus the more direct and simpler routing in this project. Are the MGN12 linear guides adequate for a 2′ x 4′ table or are more rigid guides more appropriate? Arrakis uses substantially larger motors than Lewis recommends here. This table uses linear guide rails and carriers, much smaller than the extrusions used in Arrakis. Rehorst’s robust rendition (Arrakis) and I’d like to get some input before I start spending money on the wrong things. I’ve been studying the sand table referenced here as well as Dr. Posted in home hacks Tagged kinetic art, kinetic sand, kinetic sculpture, sand, sand sculpture Post navigation It’s a great build that focuses on the smaller details like noise that can make a big difference to the final experience. 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. 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. Low-cost pine is used to build most of the table, with oak used for the attractive bare wooden top. An Arduino and Raspberry Pi work together to command the stepper motors to create various patterns in the sand. ![]() On top of the table, a metal sphere attached to the magnet moves through craft sand to draw attractive patterns. The table uses a Cartesian motion platform to move a magnet underneath a table. is here to show us that it’s entirely possible to build one yourself at home! Many of us have marveled at art installations that feature marbles quietly and ceaselessly tracing out beautiful patterns in sand. ![]()
