Warning and disclaimer: Experiment at your own risks. I am not responsible for any accidents or damages.

Step 1: Preparation of the Plastic Bottle

Get a plastic bottle like the one I’m using. Cut a hole that is about the size of the computer fan, near the top of the bottle. You can now insert the ultrasonic module through this hole.

Step 2: Fix the Fan to the Bottle

Place the fan over the hole. I fixed it using tape, but feel free to use glue for a more permanent solution.

Step 3: Connect Everything to the Power Supply.

Cut and strip the wires near the end of the ultrasonic device. Connect the ultrasonic module and the fan to the LED connector. You are now ready to fill the bottle and plug the power supply to enjoy your homemade humidifier!
