DIY mist maker using IC 555


In this video tutorial i am showing how to build a mist/fog maker using IC 555

Components needed
  • Piezoelectric disc
  • Ic NE555
  • 220uH inductor
  • IRF Z44 MOSFET
  • 10nf capacitor
  • 2*100nf capacitors
  • 10ohm resistor
  • 5k variable resistor

The main component of this project is a piezo electric disc the working of the piezo is very simple.Every piezo has its own resonance frequency i n our case that is 113kz. So if we apply 113kz signal With suitable voltage piezo disc will start to vibrate with 113kz frequency. If we place the piezo on top of a water surface the water will also start to vibrate.mist or fog will form due to the high vibration of water+air
(Watch the video for more detaild view)
Circuit diagram
This circuit is created by greatscott
Working of this circuit
  • Here 555 is using for genarating 113khz signal we can adjust that with 5k variable resistor
  • Using the MOSFET we drive piezo with high voltag
  • Should use 15 volt power supply
I soldered everything in a common pcb
Dont dip the piezo disc on water place the disc just above the water surface

    Nice! what if one wanted to run several piezo units? Say 8 or 12 in tandem?

      Can anyone explain how this circuit is working and what is the duty cycle of this circuit.

    Can one PCB run several piezo? do you need 1 PCB for every piezo?

    Can you please help me design a circuit for this Piezo:
    Resonant frequency = 115KHz +/- 5KHz
    Resonant impedance = ≤ 100 ohms
    Static capacitance C's = 2900pF +/- 20% @ 1 KHz
    Voltage input = 3-5 VDC
    Power source = 12 VDC

    Thanks for your help

      Que pasa si la entrada lo alimento con 12v.

      Porque no diseñas uno de 12vc que es comercial el voltaje

    why you don't use pin 7?

      Because Pin 7 is not needed here.
      (Note: The traditional 555 design examples all show Pin 4 connected to Vcc, and Pin 5 having a capacitor to ground. These 2 pins do not NEED to be connected to anything in 97% of all 555 Time designs - but people will keep connecting to Pin 4 and 5 with zero need to do so.

    Hello. Am interested in this circuit but have very little experience mapping your schematic to a breadboard or PCB. Can you please show a picture of the underside of the PCB that you constructed? That will help me visualize how the traces are supposed to run. Thanks.

    Do you have any information on how this circuit can be driven using PWM from an Arduino or Raspberry Pi?

    Hello , i'm working in a similar proyect but the circuit feeds a 141 khz LC resonator in system in place of piezoelectric disk. Could you help me with that?
