Make Your Own Super Simple Ultrasonic Mist Maker

Introduction: Make Your Own Super Simple Ultrasonic Mist Maker

About: Awesome Electronics Tutorials, Projects and How To´s

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!

    Would you put a heat sink?

    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.

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

    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

    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.

    Question 5 months ago

    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

    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?

    Can you use a microcontroller like Arduino to generate the oscillation signal instead of building this 555-based circuit?

    Question 1 year ago

    What makes the oscillation negative. Is it C1 ?
    If I put my scope before C1 and ground I get 0 - 72 V.
    However, After C1 I get Max of around 60v and Min of around -10V What could be the cause of that ?
