Thanks

Hi, thanks for the video. What is the voltage of the ultrasonic membrane?

Very nicely shown and explained, interesting math and charts, thanks! Yet MY OWN cheap China humidifier puzzles me: it consists of two thin 15mm diameter ceramic wafers with centrally mounted metal membranes. Apparently a high (108kHz?) vibration is induced by the piezo effect. The bottom ( and NOT the top!) speaker like metal sheet has many tiny 5um holes. These seem to generate the cool mist visible above the SOLID (no opening AFAIK!) MEMBRANE on top of this diffuser. A wick feeds the bottom punch-hole sheet with water. How does the water get from in between these two thin metal sheets to the top surface, escaping the speaker-like membrane?? If the TOP membrane had these 5000+ holes (through a microscope they look odd, probably LASER burnt?) I'd understand the principle, but the switched order of these metal sheets puzzles me endlessly. These 50c atomizer plates are not very reliable, yet they do generate a quite impressive mist at a really low power: less than 1W feeds the circuit board, the activator membranes and the LED illumination. Of course this small scale device does not really change the room climate, but with a little fragrance added it creates a neat aroma in its vicinity. Just HOW the "speaker" gets access to the mist underneath it's top membrane escapes me..just like the mist..

as expected bro is asian

thanks good video

At 4:19 Did you mean to say Copper "Rod" not "Tube" because a tube is also hollow, which is what I thought was what made a Heat Pipe a heat pipe?

That's a really good explanation. Thank you!

I did not know that proximity effect is so evil. That would explain, why some inductors perform so poorly even though the wire is smaller than the skin depth. Thank you!

Aren't you forgetting the LED in you watt usage calculations? 9.7-0.6-[LED draw]

That can’t be true about the dust. I live on the ocean. I believe it’s because of the glare of the water from the ocean.

Very stupid experiment. Why did you include water evaporation??

Excellent sir

The main difference is the size of the condensing unit. Scale it up to much and you only get cold air, without noticeable condensation.

When the coils are close, the magentic field of each individual wrap has an affect on many neighboring individual wraps. When the coil is spread, the magetic field only affects the closest neighbors. See inductive choking.

Informative. Synthetic fuels almost eradicate the soot from its combustion. Thank you very much.

Excellent explanation. Thank you very much.

amazing thx u!

Wow, I guess them perfectly just from the feel.

Is AC resistance (skin or proximity effect) increased with higher currents ?

Thank you for this simple but effective demonstration. I had been studying skin effect for coils I am making, but was puzzled why litz wire was specified with a much smaller area wires for a frequency than the skin area alone would suggest. I believe this must be due to minimizing the proximity effect.

Very nice video I was impressed

The sky at sunrise appears red and the sky at sunset appears yellow. If light is more scattered in the evening, shouldn't the sky be red rather than yellow?

Thanks Denis very informative

This was great.

I want you to be tutor for my son

Superman may not see temperature differences, but he may see that one of those "rods" is actually a pipe!

Great video. On to Part 2.

I’m looking for an efficient way to create clouds in the sky. Could this principle be used?

If you seal the cup / put a lid on and had the heat pipe go through the lid, would the heat pipe cool down the water to room temperature? Would that happen fast?

Just check if PM or AM and you'll know the answer.

Excellent video! If you feel like it, please do one about the humidifiers that have the piezo transducer at the top of a wick sticking out of the water (or link to it if you already did one). Thanks!

This is great!

The earth is not rotating.

Thanks for creating this vid; the explanations are very intuitive and easy to follow :) .

🙏🙏🌹🌹

Good explanation 🙏🏽👍🏽

Denis y w.. we have the same humidifier. It was working fine but suddenly when we adjust the timing of humidifier and as it starts the small fan… the motor stops its own. Why does this happen? How can we fix this humidifier back to normal?

Very good videos the others are so dumb and don't explain

OMg! such a great video!

Out of all the dumb, disastrously long videos on the internet about humidifiers, this was the best one, not dumb at all, and was the most informative with actual testing and data. Thank you for cutting through the stupidity. What a breath of fresh air.

Perfect. Answered all the questions and then some.

Great video

This was really well presented 👍🏽 thank you! The Smashing Pumpkins song "Soot and Stars" brought me here ✌🏽

love it

Yes, Yu can! Are the windows partially opened, so that there is a change of pressure in the wagon?or are the tracks different inside a tunnel (different frequency of vibration)?

你的影片做得很讚！ 🇹🇼 ❤️ 🇭🇰

Keep going..!! Very informative video,we need more of such content..You deserve more & more subscribers & views, likes

At higher frequency that your graph is showing the skin is more important.
