Ultrasonic Mister/ Fogger. A brief test and look

[@subhadradehury4902]

Mine was working fine then suddenly stopped. is there is a possibility of any damage within the circuit as i guess the current is not flowing through. how could i fix it or check it what is happened inside. mine is a bulb humidifier.

[@3D_Printing]

Same for me, stopped working. Some family members had a similar device to look like smoke in an electric fire but these also fail after a bit of use. Note kept wet all the time as we must. So junk

[@dreletronica]

Eu tenho um igual . Cápsula piezo é bem simples . Verifique se não tem fio quebrado , ou sujeira acumulada na placa . Eu limpei com uma lixa fina . Se tiver um osciloscópio você poderá ver o sinal de frequência entre os fios do piezo😊

How long these things last with continuous operation? Will the ultrasonic membrane clog when using tap water due to salt buildup?

[@LEO-xo9cz]

I am wondering the same thing. Distilled water is definitely the best.

[@trupyrodice4462]

I’ve had mine in continuous operation for 4 months now, I just make sure to clean the disk -gently- with every refill Looking for any limescale or hard mineral deposits building up on the working side of disk. Many people think the disk is dead when it only is in need of good cleaning by gentle, and I mean gently -I cannot stress this point enough, with a pointed object small enough to chip deposits off. You could also use vinegar water soluble to help loosed and dissolve mineral build up. Done successfully it will work exactly as nex

@@trupyrodice4462 do you neend to have a circuit like that or can you just attach it to a battery and how many volts

[@TheSmile1976]

I was close to by these things, thanks for showing. Thought they are working under the water, not at the water level. Due to this, these foggers are not useful for my project. Thanks a lot.

[@ensandost8410]

Does it boild the wather and then smoking it or what is the process from wather to smoke? Is the smoke warm or cold?

[@3D_Printing]

So far as I know it does not boil. It more vibrates the water into very fine mist which can look like steam

[@dreletronica]

Não tem nada disso ! Água e fria normal . O processo é por quebra das partículas de água pela vibração do piezo !

[@sattimanda5901]

I want to spray the water mist to little longer distance , so how to do it ? Can i boost the piezo electirc disc by transistors ? Or can i get little long distance by buying big disc than before ? Plz clarify 🙂 i am currently involved in project , plz help me ❤

[@3D_Printing]

Sorry ; I don't know

[@dreletronica]

Uma solução mais prática e barata , seria posicionar micro ventilador na saída da nevoa . Eu já fiz isso

[@ShreeChoudhari-q1w]

I want a ultrasound transducer which could produce a ultrasound waves at a 40 khz any suggestion please

[@3D_Printing]

No, I broke mine, sorry

[@creeperbombrf3898]

does the curcuit board make the disc pulse as well or can i run pure voltage through?

[@ZeroMass]

113khz. ..

[@trupyrodice4462]

You have to run it with the board as it has to have a specific Frequency to make the disk work.

[@moNYTx]

Do you have a part number for the mister?

[@zulhakimzulkifli6040]

hi is it normal to get shock when i touch the white damper area when the device is on? cause im afraid it might have electric leak

[@lukmo7999]

Yes its normal

[@MichaelStephenLau]

5V you won't feel.

[@LEO-xo9cz]

I want to build a dry run protector to shut it off when there is no water. Any idea? What happens if it runs dry?

[@HaloHunter2552]

Peizo burns out.

[@LEO-xo9cz]

@@HaloHunter2552 What can I build in to prevent that? I have read the the current changes when it warms up due to being dry.

[@HaloHunter2552]

@@LEO-xo9cz One way is to manage things with a micro-controller (What Arduino runs). You can have a sensor, like a switch on a float that tell the circuit to shut off (multiple sensors may solve the same issue interchangeably, float is just one idea.). You could try to make some mechanical shut off, again maybe with a float, so that when the water level falls, the circuit is broken. This is simpler that a micro-controller if you don't know how to use one, but would be more difficult to tune/configure so it's reliable. Depending on how often you are checking on the device, you could just have a large reservoir kzbin.info/www/bejne/o6uYo5Kmh7Cdq68. I plan to use this design since I'll be checking my device periodically, so I can easily refill. This setup will maintain a (roughly, if the falling momentum doesn't push out a little extra) constant water level. You can combine these methods.

[@3D_Printing]

I think there are some for electric fires that pretend to be smoke, to make the fire look more real; I think these have a switch to stop burn out is they run dry

[@akashdebnath8595]

How is maximum voltage for it?

[@ZeroMass]

Pay attention, he mentioned it.

[@gamingsovonsahoo3367]

24v

[@nikohiroyagami8377]

How to fix it. I have that membrane but not working.

[@3D_Printing]

Sorry don't know; all I can suggest is to obtain a kit off eBay

[@mikejoshuavalin6918]

how about the mini mist maker got broke into the center of the mist maker back and front

[@ZeroMass]

Doesn't submersing your fingers in a liquid with an ultrasonic emitter damage your nerves? 🙄

[@3D_Printing]

Sorry I don't know, but ultrasonics is said to be bad on the body, but some used for pregnancy, etc... www.researchgate.net/post/Do_ultrasonic_waves_have_any_negative_impact_on_humans2

[@jozefnovak7750]

Super!

[@CAMacKenzie]

a wick or a cotton ball?

[@lokeymaddy]

Mist doesn't comes out what can i do

[@3D_Printing]

I had to hold it only just level with the top of the water

[@1MNUTZ]

these things always fail on a humidifier

[@josephm.delacruz3218]

Can you please give me idea how I can convert the power supply from 220v to dc supply

[@3D_Printing]

a PSU or a transformer

[@blahblahblahblah2837]

Get a power supply from some christmas lights or a phone charger cable. Make sure the output voltage (DC) is between 3v and 12v for this board. Change the end of the of the cable to match the input for the board and that's it

[@muhammadaizat9695]

Where do i get the nodule?

[@Ana-nu9dr]

How much amperage

[@3D_Printing]

I don't know, sorry

[@josephm.delacruz3218]

How many volts

[@3D_Printing]

I believe Ultrasonic is classed as High Voltages, so the board step boost, it up to that Input 5 V to about 12 V DC
