Homemade ultrasonic atomizing humidifier 1.6 MHz

[trongie]

you can find an actual one on deal sites for <15 shipped to your home why bother

[delphinny]

where can we buy the transducer from? thanks

[TheRasbx8]

I would like to build one of these, but I can't get kt805im transistors where I live. Do you know of some other transistor that would work?

[KaVcr]

@TheRasbx8 Yes, any non-Darlington power NPN with Vceo≥60V, IC≥3A, hFE≥20 and fT≥10 MHz

D44H8 / D44H11 are good enough.

sorry was confused , never seen it referred to as a crystal, i usually think of a crystal oscillator when i hear crystal, but where did you find it for $2 i cant find them anywhere, can you please post a link? also i dont think russian schematics translate well to english, where your transistor is it says vt1 kt805nm , but a transistor is not vt ,it is Q in a scematic, when i seached google only pages came up were all in russian, so russians must use different letters for components in schema

[bulletproof2353]

@kavcr what do you mean crystal, that is not a crystal, its an ultrasonic transducer, the link next to where it says crystal takes you to an ultrasonic transducer ,not a crystal , but where do you get the damn transducer , and for $2 , the site in the link doesnt sell them unless you buy 10000 ,and i cant find any anywhere for less than 15.00$ and 6.00 shipping , so can you post a link to a site where i can buy thr transducer , for 2 $ ?

look at all those inductors! do you know about led driver circuits?

[alejandramacma]

hi! i need so badly to know how to do the same.. it's part of a proyect and i'll be so thankfull if anybody tell me what do i need??

[andrespereyda]

@alejandramacma an education

[Video85Man]

make a how to video?

[brbajid]

I can hear you constantly blowing on it to release the steam, that doesn't sound too convenient...

[gettingahandle]

Double, double toil and trouble;

Fire burn and cauldron bubble.

[TheRedTesla]

hi, was wondering if you had a more detailed list for the parts?

[afdhalatifftan92]

Hey< I just realized that you already link the circuit... Lol!

But, few question tho...

How did you manage to make the inductors?

What kind of core did you use? Air-cored or ferrite-cored?

How what's the wire gauge for those inductors?

Thanks!

[Dri0m]

@afdhalatifftan92 just buy some inductors somewhere :D

[afdhalatifftan92]

Could you make a how-to videos?

I need it so badly!

[pikachuthesquirtle]

where do i buy the crystal?

[meghterb]

I bought Proton humidifier last week but I don't know where do I fill the water.

[snake172]

fuk that's so cool, make a "how to" video and ima making one asap!

[Xonoxsuka]

Big heat sink ;) what voltage are you applying? thanks for sharing.

[KaVcr]

@Xonoxsuka Big heatsink is because of semi-linear switching mode .

About 30 V.

[ronaimwal]

Can this be built cheaper than buying one?

[KaVcr]

@ronaimwal Why not, especially if you have 2$ for the crystal, electronic trash is available and you are not afraid of soldering?

[boxa888]

@KaVcr so your making a basic radio circuit and then feeding the mhz signal into a crystal??

[KaVcr]

@boxa888

Yes, crystal is a part of the generator as a positive feedback element.

[whitemisa]

that is sooo coll!
