A Zen Sand Table powered by GOcontroll Moduline Mini brings precision motion and calm creativity through embedded control and smooth automation.

The Zen Sand Table blends meditation with precise engineering. Beneath its calm surface, a GOcontroll Moduline Mini directs an XY motion carriage that moves a steel ball through fine sand to create intricate geometric or organic patterns.
With MATLAB Simulink and Node-RED support, the Moduline Mini enables real-time motion control, smooth acceleration profiles, and remote operation — turning mindful art into a refined kinetic experience.

The GOcontroll Moduline Mini is a compact embedded Linux controller with four module slots, two CAN interfaces, and a powerful quad-core NXP i.MX8 processor.
Its CNC-milled aluminium housing (IP67) ensures reliable performance even in challenging environments.
For the Zen Sand Table, this translates into flawless stepper or servo motor control, feedback management, and connectivity via Ethernet or Wi-Fi. The controller boots quickly and runs Simulink models or Node-RED flows — no coding required.

GOcontroll’s modular architecture allows the Zen Table to use output modules that drive PWM or bridge control for both axes.
The Moduline Mini’s embedded accelerometer and internal monitoring functions help ensure vibration stability and repeatable motion.
With MATLAB Simulink, motion profiles — such as curved trajectories, easing functions, and synchronized acceleration — can be built visually and executed in real time.

Node-RED comes pre-installed on GOcontroll controllers, allowing intuitive graphical programming and remote dashboards.
Users can:

• Upload or generate pattern files from images or equations.

• Schedule drawing sessions with simple dashboard controls.

• Adjust light colors or intensity as the sand design forms.

The dedicated GOcontroll Node-RED nodes connect directly to hardware modules, translating visual designs into precise movement with no need for code.

Integrated RGB LED control adds dynamic illumination to highlight new patterns.
Connectivity Guard services maintain stable Wi-Fi or Ethernet links for cloud dashboards or remote uploads, while Bluetooth pairing via the GOcontroll Android app allows local control and quick diagnostics.
Whether displayed in a spa, workspace, or gallery, the table can be managed securely and silently from any connected device.

The Zen Sand Table demonstrates how embedded control can merge engineering precision with meditative design.
By combining modular hardware, open-source software, and a flexible programming environment, the GOcontroll Moduline Mini brings serenity and innovation together — letting creators express motion, rhythm, and calm through technology.
