Make Your Own Super Simple Ultrasonic Mist Maker

In this project I will be showing you how to create a simple driver circuit for a 113kHz ultrasonic piezoelectric disc. The circuit basically consists of a 555 timer circuit, a MOSFET and a couple of complementary components. Along the way I will also show you how the commercial product works. Let's get started!

Step 1: Watch the Video!

The video gives you all the information you need to create your own ultrasonic mist maker circuit. During the next steps though I will present you some additional information.

Step 2: Order Your Components!

Step 3: Build Your Circuit!

Here you can find the schematic of the 555 timer circuit as well as reference pictures of my finished board. You can also find here the super simple TC4428 circuit which was featured in the video. Just in case you want to try it out as well.

Step 4: Success!

You did it! You just built your own Ultrasonic Mist Maker!

i see 10 componen in the picture (include piezo), but the list only 9 componen (on aliexpress), isn't it ?

[bigrenegade57]

In the schematic he only shows 9 components being used. One of the capacitors shown in the parts is not shown on the schematic yet in all the pictures it is connected in the circuit.

[brannorm]

It is 470nF (0.47uF - 474 marking) capacitor missing on the schematic, which is soldered between 1 and 8 pins of 555

[hardikbagaria]

In the picture he has added connector so he dint soldored the piezoelectric disc directly to the board but he connected the connector to the vero board he also connected connectors for 15v input

[sanjeevbaburajput]

I am trying to make the circuit using 25mm disc with the exactly same circuit as given above also the frequency is 110khz to 120khz but nothing is happening.Tried many times but not getting the success any help please.

Hi, I'm trying to use this schematic for an Arduino project of mine. The only thing that worries me is that we will be using the Arduino output Voltage for this project and I am unsure whether or not it will work. If anybody has any information about this, I am waiting on the parts to ship so I can't test it yet.

[Reidar_Vik]

Very interesting. I would like to implement an atomizer like this to a self watering plant pot just for the visual effect. I have plans to connect it via a micro:bit first and than maybe try out a smaller microcontroller later. If anyone has any input for me about that I would be happy to hear from you.
Second, I wonder if there are any precautions to make when just dipping this thing into water? Shortcut problems??

[highroller_ch]

Hey, that’s a pretty nice circuit and you did exactly what I needed. I bought several boards myself to get behind the commercially sold circuit. Is it possible to replace your 5K Trimmer with something else, so the individual tuning to 113kHz is not necessary?

Thanks for your work and best regards
Chris

Helo great scott i am a diehard fan of you. And sorry to say this i tried this circuit lot of times and everytime MOSFET will heated up and destroyed whats wrong everything i cross checked looking for your reply

[lasanthaliyanawatta]

Would you put a heat sink?

[EDISON SCIENCE CORNER]

yeah it is better to place aheat sink

[t_henderson]

I had the same issue, ESC. One thing that helped was getting the trimmer resister to about the right range of resistance so that the 555 timer is outputting a signal that's not super low or super high; both extremes causes the MOSFET to overheat very quickly. I have a cheap little oscilloscope that was invaluable in tuning this; without it, I'd probably have given-up a while ago.

I also doubled the size of the inductor, as mine got so hot it started smoking.

[alireza.mhz197]

Hi, does this circuit work for an incubator that should be on 24 hours of day?thanks🌹

[Zun441]

I change mosfet to irfz44n ,put 14 v ,and no mist,just slow sound at piezo,what the mistake

[EDISON SCIENCE CORNER]

Oops

[angeli1212]

hi .. im trying to make this circuit and I'm wondering which power source would be better, a 12v 23A battery or a 12v 3A DC power supply? also I'm making it on a bread board and kinda confused where to plug in the voltage on the 15V branch or vcc branch? pls help thankyou

[hosam.hhhhh15]

غير واضح المخطط

[SeetC1]

Hi, sorry im quite a electrical newcomer. I trying out this mist maker plate.
Can this mist maker run on 5V battery?
Or can i use a 12V battery to run the circuit?
Where do i pluck in the battery in the VCC or the 15V branch?

[dadko]

سلام
من از کشور ایران کارهاتان را دنبال میکنم.کاش میتونستیم از داخل ایران خرید کنیم. ولی متاسفانه تحریم هستیم.
موفق باشید

[RobertM841]

Hi! How can i amplify the current of the 113khz signal so that i can series a 10 piezo ultrasonic disc?
