Introduction: DIY MIST/FOG MAKER USING IC 555

By visit my youtube channel
About: I am an electronics hobbyist and I love to share my works with others

In this tutorial i am showing how to build a mist/fog maker using IC 555 very simple circuit. This is also know as humidifier,atomizer lets get started.

Step 1: Circuit Diagram (thanks to Great Scott)

Step 2: Components Needed for Making This

  1. Piezoelectric disc (buy piezoelectric disc from here)
  2. NE555
  3. 220uH inductor
  4. IRF Z44 MOSFET
  5. 10nf capacitor
  6. 2*100nf capacitors
  7. 10ohm resistor
  8. 5k variable resistor

Gather all components

Step 3: The Piezoelectric Disc

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)

Step 4: Working of the Circuit

  • Here 555 is used for genarating 113khz signal we can adjust that with 5k variable resistor
  • Using the MOSFET we drive piezo with high voltagShould use 15 volt power supply

Step 5: Soldering

This is nothing just solder everything according to the circuit diagram

I soldered everything in a common pcb

Dont dip the piezo disc on water place the disc just above the water surface

Step 6: Thanks...!
