While searching for a humidifier to use at home, I saw many cool ultrasonic humidifiers and wondered if I could build myself a cheap one. I made this simple humidifier using an ultrasonic mist maker / fogger that I found on eBay. This is an easy DIY project you can make for less than 10$. As you can see, it works fine!

Check the videos for a complete step-by-step guide for building this humidifier or to see a quick test with the ultrasonic module.

You can use these homemade humidifiers for your home or for any project requiring humidity. It’s perfect for a vivarium / terrarium, greenhouse gardening, mushroom culture, wine cellar, etc.

--------------------

Materials required:

-Ultrasonic module and power supply (7.25$ for both on eBay.com, CA, UK, DE, FR) (Aliexpress)

-Computer Fan (eBay - 1.25$) (Aliexpress)

-DC connector female (eBay - about 1$) (Aliexpress)

-Plastic bottle and tape

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!
