I built a super satisfying sand-drawing gadget that creates beautiful patterns, wipes them clean, and repeats endlessly. It’s relaxing to watch, fun to build, and surprisingly easy if you have a 3D printer!

In this video, I take you through the full build — from 3D designing the parts in Fusion 360, to printing, assembling the electronics, coding the ESP32-C6, and finally testing it with real sand… well, actually salt + turmeric because I couldn’t find white sand in my town.

This project uses:

ESP32-C6: https://www.waveshare.com/esp32-c3-ze...
N20 motor with integrated driver: 15RPM
ARGB LED strip: Genric

You can control this gadget entirely from your phone: speed, direction, LED colors, effects, and more!
