Ultrasonic Mist Maker || DIY or Buy 

Agreed! (Congratulations on the number two top comment too!... I think...) 10:47 PM 6/19/2019

Ive failed at so many things, thanks for saying that. Life is worth the experiment.

Depending under how much pressure you work on a task a failure can eat you away much more than you would think. Nowadays development departments are no kndergarden, the persons who are the loudest/aggressive/pursuing/stupidest are promoted, thus many experts who think in silence for themselves work at home in their basement or just keep calm... Depending on the middle to low management corpus, engineers suffer more ore less for less money than the con artists of management. The moment the "art" designer and economy enginer is valued higher than the "application/design/electronics engineer" who do solve the problems, you should just change workplace :-\

Agree, and it would be great if Scott could overcome it and make the sequel videos, thus he reviewed what is actually the problem with the project in the previous video. Then he can explain the ideal of circuit behavior and its output and also practically correct the mistaken project.

He was being self-deprecating.

Thank you ;-)

No sabía que Proyectos LED seguía a GreatScott. Que pequeño es el mundo.

Proyectos LED sounds alittle bit dirty

*peace... GreatScott pronounces it like that :P

Una leyenda frente a otra XD

Agreed 100%.

Don‘t know if you‘re seeing this but I really feel you. I always feel like “can’t be that hard right?” only to realize that it realistically is not that easy.

This is how vaporizers work without boiling water

You cannot achieve higher vapour pressure using this vibrator method than what we would get normally at that temperature. It only acts like a catalyst that speeds up the journey to equilibrium point but doesn't shift the equilibrium point.

I bought a mister kit and hooked up a oscilloscope to it to find the frequency of the driver, it reads a solid 114khz when it’s misting water

@@3nealweber3 If you can detach the transducer, you can hook it up to a NanoVNA or any other network analyzer that can measure the S11 parameter and look for the mechanical resonance frequency of the transducer (the frequency with minimum reactance). This is the frequency your mister should be running at. You will still get output at different frequencies, but running at the resonance frequency will provide more mist at the same output power. This measure isn't exactly right because the output is probably driven through a transformer and the transformer's leakage inductance should be considered, but it's close.

SCWfan06 do you watch ElectroBOOM

RobertTunaru Is that a question?

boom, here comes the boom,... oh wait not that movie

Hahahahah

Mother of all

I beg to differ. It does take engineering skill but there is probably a cheap DIY way of driving that transducer at 1.7 Mhz

@@metatechnologist but wouldn't it be great to scale this up for a greenhouse or sauna, a massive high quality water vapor belcher

The pulse transformer sounds like it could work. I might give it a try.

yes yes keep trying Thanks

GreatScott! This will be too simple to you. Lol. Btw, i drive my transducers through this transformer approach, which works like a charm. The tranducers has its own resonance frequency, where you dont have to worry about capacitors or what so ever.

+GreatScott The signal source can be an LC resonator.

Hi. I need your help. Can you send me your schematic about this circuit. I tried but it not work. My email: learningisglorious@gmail.com. Thank you very much!

1.7 MHz is pretty forgiving frequency to work with. Most transistors produce plenty of gain well into the VHF range

Yeah, I was thinking the same - those half bridge/full bridge drivers are made for driving high frequency transformers in switching power supplies and similar stuff where much lower frequencies are used. Using 1,7 MHz for those circuits would not be very efficient - and large power MOSFETs and IGBTs made for high power are too slow to work properly at that frequency. They would probably never be fully on or off and mostly work in linear mode with huge losses and wouldn't handle much power at all. The built in "dead time" of 150-400 nS in those drivers are also needed for those, to ensure one set of transistors get enough time to turn fully off when the other turns on. For 1,7 MHz those MOSFETs are probably not the best choise ether - there are other transistors more suitable for RF (I havn't very much experience my self working with frequencies that high - most I have played with is audio circuits and power circuits, that range from DC up to about 100 kHz)

Pier Aisa do you speak english

Wow, All this is beyond me right now. I would probably just buy one as well. But as a hobbiest, I appreciate how you can share your failures and it seems like it must have been fun attempting to problem solve this issue with the knowledge you have! Two questions, "did anyone ever successfully do this in an affordable way?" And, "is there any way to make sure the components don't corrode?" There was some rust on your oscillator/atomizer which perhaps could have affected it's performance but what do I know.

For what it's worth, they do sell multi disc models, but they aren't as cheap. 3 disc are easy to find, and I think I've seen a 5 or 7. I bought a 3 in the past and it works great for those mist fountains where I feel the single discs are lacking.

Sony look at the guts of a sonicare toothbrush, way different principle.. they use a layer steel transformer style in the shape of a tuning fork with coils wrapped around it.. very interesting.

It is sealed with potting compound

If you wire in one more piezo-electric disc with the one that's already with that item, it will decrease the frequency.

@@novadelp5969 why?

Sounds interesting :-)

I can imagine, but would be *cool* to see Scott make one, esp. low-BTU solar powered.

Its pretty eazy

I would like thermoelectric

How about solar heated absorption type compressor, then a high btu capacity 'cold battery' to store the temperature negative energy 'cold' then a water pump to pump this fluid through a radiator and a fan to cool the air in a room.

DIY nuclear power plant

This. Or maybe a raspi zero or greater as the controller.

That would be creative its only been done like half a billion times all ready?

Or even a Table CNC Router

Not a problem. Most of the cost of a 3d printer has to do with the steppers themselves. The more granularity, the higher the precision. The higher the precision, the slower the speed. The faster the speed, the more processing power required and the more momentum tries to sabotage you. It's a battle where physics is constantly trying to kick your ass.

if you can make the mechanic parts its not a big deal to build diy 3d printer.

That was my plan but I could not access the circuit from the mist maker. See the end of the video.

Fernando Zigunov very accurate.

You need add inductance at 5.05

Plus protoplasm

Thanks

Don't know what I enjoy more, the content, or the awesome accent of his voice, haha!

Honey FPV ...and you will receive them in January....if your lucky

Upcycle Electronics i usually get my items in like a week to two weeks from aliexpress (in belgium)

Honey FPV I just ordered a bunch from AliEx myself. I bought from 10 different sellers. A few of the sellers were fast, but most took a week or more just to ship the item. They print a tracking number but they don't actually process the order and take it to the logistics carrier right away. I wish more people would write reviews that state: 1.) Order Placed: (DATE/in Chinese Time) 2.) First Tracking Number Ping: (DATE) 3.) Delivered: (DATE/number of business days) 4.) Condition/product quality/etc. Even the listings with better feedback lack this kind of info. In my opinion, the delay between the order paid and first tracking number ping by the logistics carrier is the most important feedback possible. That info tells a buyer everything about the quality of the seller. I try to order from sellers that have better feedback, but it's still a shot in the dark. I placed my last order 10/9. I've received 3 things already but there are 3 more that are still in China right now according to tracking. The fastest I have received stuff so far is 9 days, and I'm in Los Angeles California USA. This is one of the largest trade hubs with China as California is the gateway to the mainland US. If the seller is responsible I should get stuff very fast.... That's been my experience so far, but this is my first real experience with AliEx as I am looking for eBay alternatives for the small stuff.

Link product plz

@@UpcycleElectronics could you please post the link

I am 555 timer . Nice to meet you

Hi :)

fuck you. fuck you for being so rare!

Why does that happen? It feels like it's being crushed

Answers to why?

Yeaaaah bruh ! Me tooo .....

Co-worker ask me to try and fix his humidifier decades ago, on the side of the device's it said ultrasonic, thought that was just BS packaging to impress consumer's, that is till I put my finger on the element, Ouch, not BS packaging after all.

Yeah it hurts like all hell

I think the project size is too big.

Are you talking about those 10 dollar ones from eBay?

Utkarsh Amitabh Srivastava yes I am

Absolutely DIY, unless you don’t mind the usual HPF bulls***.

The Lame Gaming Channel good luck to make a 50w amplifier that has got bluetooth 4.0 and cost less than 10 dollars and not bigger than your phone

yeah, i was thinking the same. just use an op-amp to create a DC offset and you'll have an AC signal, yeah?

Correct

GreatScott! Kahan se milega

Does not work. Tried it.

BJTs are much faster than MOSFETs as far as I understand, and cheaper. Maybe a Darlington bridge or totem pole of some sort would work?

Did you play with the value of this capacitor? I think the value may influence the impedance vs. frequency response.

GreatScott! I could never get the hang of mosfets but as far as using a capacitor to create the a.c. would you not have to replace the piezo in the circuit with a resistor then where the resistor joins the f.e.t connect a decoupling capacitor from there to the piezo and then from the piezo to ground. I guess you could replace the f.e.t with a transistor

Searched this comment!

I wished I was as smart as he is , ( at least with electronics ! )

Yes, he does use breadboards. In almost every single one of his videos. It is just not a good idea to use one in high-frequency circuits because the parasitic capacitances. The mosfet drivers were there to turn on the mosfets on and off really fast, because you need to charge and discharge the gate quickly.

I solder stuff in mid air all the time. if its convenient, that is.

Hi

yes i want it

Make sure the connection between the balls and the piezo is tight enough.
