‘Water Curtain’ is Arduino-Powered, uses 3D-Printed Valves & Nozzles to Print Letters & Drawings with Water #Arduino #3DPrinting

Tecnoateneu Vilablareix designed and fabricated this ‘Water Curtain’ that was recently on view in the “Temps de Flors” floral exhibit in Girona. What’s hard to see in any of the documentation below is the sheer size of this thing – the water curtain is ~6’x10′, cycling through 500 litres of water!


3ders were first to report on the project and their blog shows multiple images of the build process and 3D-printed parts and pieces before assembly:


Atmel’s Bits & Pieces blog picked it up to further elaborate on the multiple AVR microcontrollers powering the project, including four Arduino Nanos controlling the valves and one Arduino Mega to route WiFi commands.

Those valves you can see being tested in this video:

And here’s a daylight-lit video showing elements of the project a little more clearly:

Awesome project. Hat tip to 3ders and Bits & Pieces for blogging this & congrats to the Tecnoateneu Vilablareix team on a truly beautiful build.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
