Gastly Humidifier Overview: LED-Lit Water Fog

The Gastly Humidifier, 8cm in diameter, creates a mesmerizing water fog illuminated by LED lights. The fog is generated using an Ultrasonic Atomizer and spreads from Gastly's body in all directions.

Important Safety Note

For health safety, use only clean water and operate the humidifier in open spaces. Unclean water or containers can cause the spread of bacteria through the fog.

Components and Assembly

  • Ultrasonic Atomizer and Driver
  • LED Strip
  • Fan
  • Adjustable Resistor
  • Screws
  • 5V Battery or Power Plug
  • Wires

The LED strip lights the fog, while the fan disperses it outward.

3D Printing and Assembly Steps

  • Print parts without support structures.
  • Install the atomizer in the lid, ensuring wire placement and securing with screws. Avoid over-tightening.
  • Connect to power and check functionality.
  • Attach the fan using appropriate screws based on thickness.
  • Connect and adjust the resistor to control fan speed and fog density.
  • Route wires through designated holes and follow the circuit diagram for wiring.
  • Assemble the holder.

  • Additional Considerations

    • The LED strip appears blue with a hint of purple on camera, enhanced by darker backgrounds.
    • Avoid direct eye exposure to intense LED light.
    • Conceal wires and battery for aesthetics.
    • Only LED strip and fan are moisture-resistant. Protect driver board and power source from moisture.
    • The internal water tank has a limited capacity (about 10 minutes of fog production), with a separate compartment to collect condensation.

      Enhancements and Future Plans

      Consider pairing Gastly with additional structures (like a castle) for more space and functionality, allowing better concealment of components. Stay tuned for future designs.

      If your fan is 7mm in thickness, use 4 of M3*10 to fix.

      If your fan is 10mm in thickness, use 4 of M3*15 to fix.

      Connect the adjustable resistor with the fan based on the circuit diagram.

      The adjustable resistor is used to control the speed of fan. Hence control the fog. Shows in the GIF.

      Use 4 of M3*5 to fix the middle part and back_A part.

      The wire of LED strip goes through the same hole which the wire of atomizer goes through.

      Wire those electrical parts based on the circuit diagram.

      Assemble the holder.

      My LED strip is blue light, but seems a little bit purple in camera. And the backgroud affects. Darker backgroud seems better.

      Don't stare at the LEDs directly for long time. The light is intense.

      You can find some ways to hide wires and battery. (First picture)

      The LED strip and fan is ok to work in a moist condition. But the driver board and battery or power supply are not.Be carefull.

      The water tank inside Gastly's body is not big, filling with water once ,it can provides the atomizer make fog for

      about 10minutes.

      Some fog attaches on the the suface inside the body, they will gather into drop. To avoid the drop falls out, I add a room to store the water drops. (Second picture).You need pour the water out before it's full.

       

      A single small Gastly has many limitations.

      You can put Gastly together with another strcuture. Provides more room,that will solve many problems.

      For example,in the third picture, Gastly with a castle.Then you can put some circuits ,wires, water tank out of Gastly, and hide in the castle.

      I will try to make one of this editon. See you the next time.
