How to blow fire from water

This effect has been known for a long time, and is used in some fireplaces and concert lighting devices, but there is very little information on how to do this, which I want to correct with this post.

Part of the equipment

From left to right:

• Distilled water;
• 90 mm fan;
• DMX-controller Velleman K8062 ;
• DMX decoder BESTEN DMX Decoder 350 ;
• LED RGB-lamp MD-9P ;
• 3 Chinese ultrasonic mist generators (bought in the Live Water Online store).

As it turned out after the purchase, the DMX decoder is a real designer, which you need to independently solder, assemble, test. But it costs significantly less ready-made solutions, and most importantly - it works.
One of the fog generators turned out to have its own non-programmable flashing LED-lamps, but, fortunately, their light had absolutely no effect on the final result.

Installation diagram

Fog generators are installed at the bottom of the container. The generator has a membrane that vibrates with an ultrasonic frequency, which leads to the formation of a low pressure area near the membrane (in other words, “almost vacuum”), which, as is well known , leads to water evaporation at room temperature.
This cold steam is driven up by the fan and illuminated by a LED-lamp, which is controlled by a DMX-controller (in the video, the color of the glow was static).
The diaphragm restricts the outlet opening, which, according to Bernoulli’s law, leads to an increase in the fog flow rate. The hole cross-section was chosen in such a way that the final effect was as close as possible to the flame.
I tried different forms of the diaphragm, different position relative to the lamp, and this arrangement is optimal.

Another pair of tricks with water

Levitating water 1

Water drips with a certain frequency, the strobe light shines with a different frequency, which leads to the animation effect, i.e. a person sees only certain frames, but does not see intermediate states, since The lamp does not work. Thus, highlighting the necessary animation frames, you can achieve this effect.

Levitating water 2

In this focus, the frequency of the subwoofer and the frequency of the camera are selected, which leads to the observed effect.
