I’m going to post a series of videos in YouTube willing to reach 1000 subscribers so we can get monetized on the channel.

You guys could help a lot commenting on the videos! Liking sharing and cling on the bell… please try to watch the whole video…

Next video I’m posting is about how to make old refrigerators work better without forming ice and reducing its consumption a lot!

Please comment anything will make lot of difference in the reach of the videos.

I’m going to make an English version of this video too… and I’m designing a better equipment to make this control where you have a seasonal adjust by having a second temperature sensor that gets ambient temperature and according to it compensate the maximum and minimum temperatures for the compressor… this will make a small adjust for the hot and cold days …automatically!!!

Hope you like this first português version

##### Maybe let’s design the water cavity to work at a certain frequency?
« Reply #57 on: March 12, 2023, 21:38:47 pm »
Any of you know the exact size of the Stan acrylic cell? Internal diameter and length? Any other details?

I have a acrylic tube here and I’m going to use it to try get the resonance first leaving it empty with a small speaker inside… when it’s filled with water the frequency will be proportionally higher to the difference in sound speed so kind of there is going to be a calculated value I’m going to match the circuit to

I guess adding stuf inside will rise the frequency a little like the cell and something to hold the cell

My best guess is that at startup is going to behave as a sort of Lc parallel resonance since the current should drop when the resonance happen… than match the electric components to make the coils tune to the frequency

The resonant frequency of the cell may be twice that if the circuit such that every falling of the unipolar pulse wave will be synchronized with the returning of the water to the rest position…

##### 5khz
« Reply #58 on: March 13, 2023, 10:16:57 am »
I found a relation between the speed of sound and size of cavity to get 5khz basically if the cell is = to the speed of sound divided by 10 seconds the result is in milimetres…

However it changes with temperature and may change with density changing… so perhaps the resonance to be maintained may be a sweep down slightly in frequency for every train… it’s just a guess why the pll may be necessary or better!

Out cells copy of Stan are 4 inches and so it resonate at a slightly higher frequency around 7350 hz and I can tell I seen some effects around that frequency actually a little higher 7,8khz the effects were simply that sometimes it resonated at that frequency but I was not into that!

I’m going to find if the speed change with adding sodium or potassium …

Consider the following: why would you want to delay two signals? Actually if we wanted to de phase the Positive from negative pulse what if someone could make use of a coaxial cable for example to slow down the negative pulse for example… and than another coax to slow down the positive ?

I mean the coax will have the grounded mesh over all the cable allowing the negative pulse to arrive somehow later…

The frequency of the closed tube with the tube caps would be the same as if it were both sides open however the node is in the center in the case of the open and in the ends in the case of closed ends…  I guess if we had a 15cm tube cell with open sides inside a water bath having 30 cm would give a very good starting point… unluckily most my tubes were cut to that specificication of 4 inches or so to make that cell. So I’m goin to get to work with what I have or try to find some tubes I can play with here that were not cut…

Is a very happy news for me after so long to get this working!

I was thinking about the method of sensing it and maybe a piezo may be the only way to get a decent signal to noise ratio… and so it’s a must have tool in this JOB

I have no clue how I’m going to find one… I’m thinking to maybe take my air umidifier apart and take the piezo out from it place inside the cell near around 3,75 cm from bottom and see if pulsing the cell can induce readable vibrations in the piezo by analyzing it in the scope… it may need some coating for protecting from any chemicals I may want to play but first I will start with rain water or very pure… than tap and than very pure with potassium hydroxide or nitrate…  or some other chemicals I don’t know yet…

Could it be that one bifilar coil was there for the sensor… to get the signal from up high potential may be required to get the potential modulated

I just came up with an idea of how to get a better chance with the tests and it consist of increasing the force on water hundreds of times compared to what I was considering before… for this it going to have a small choke with a diode per core connected to the center electrode but one connected from up and one from down and obviously short circuiting the inner electrode in itself… the diode is there to allow the current to collapse… each L3 coils a and b are in each half of the double core transformer. Hope you understand what I mean…

The dc unipolar come from the secondary without need of diodes… and interact with maybe some 40amps field in the electrode

Even the both electrodes could have this very high current passing thru it by using a set of chokes to isolate them while having current passing across both!

I came up with this somehow after the idea of adding a choke in my dc power supply between the rectifier and capacitor and diode cause that way it work as a power sucker from the input since the section after the capacitor will work as a primary and the secondary will catch the power below the voltage that the capacitor is already charged… basically it will add up as a booster and at same time a little impedance to save the capacitor and rectifier from too high current surges…

So this choke is a bifilar choke and by that I mean herein when I referto a bifilar coil is just a pair of coils wounded together with same length…

They get a common connection sometimes… but if we want the current to be thru it it may need to be connected across the electrodes

I mean each electrode must have two connections one at each ends … a diode would be required because if you just apply a short circuit to it it will limit the collapsing voltages and there’s not going to be high voltage nor unipolar pulses so I think I finally understand why a giant diode… is a switching diode! To set the magnetic field in the cell…

The chokes could be wound around the cell for easy up  connection

I was trying to make some circuit with two diodes but I guess I was falling into what Stan call the heat resonator…

I was considering making ac magnetic field to play with the dc so the force would go up and down

Using only dc the force will be only up so it may have a natural return reaction

I remember somewhere seeing a circuit of the hydrogen generator having two connection in the inside electrode I guess was horvath…

Now is clear how he talk about so many amps

I’m going to make a video about the chokes to explain better what I mean I’m not sure I was clear enough.

##### Feedback phase
« Reply #62 on: March 16, 2023, 04:58:31 am »
As I’m dealing with a system that resonate by its physical proprieties like length

The phase of the feedback is dependent on the position of the microphone and must be tuned to get the right or most amplitude

Adjacent nodes are 180 degrees apart so from a node to an antinode there is 90

Meyer pll use filter two if I remember well and it is 180 degrees phase relationship for locking

I even had to use a coil or capacitor in the feedback to get it to tune for sensed current since current and voltage at resonance are at 90 degrees so I had to add 90 to get to resonate… basically it won’t be needed to tune the microphone but the exact position must be tuned! So it get the right frequency… with the coils it always got a little imperfection since I was not buffering the output the feedback always had some small phase difference… I guess the only way to make it different was to buttering the output or the feedback so as to be able to tune manually the phase

Diameter has an effect of lengthening the cavity and can be calculated

However I found that the calculation for a gap in a cylinder would need some more numerical analysis to get the number but for a gap of 1,7mm the frequency radially may be 138khz for water

There is also the gap length frequency that may be relevant depending of the mode of the vibration

The more I dig into it more it seems to me is about physical resonance of water in the audio range

The feedback coil of Stan had some center tap with voltage applied 5v it reduces the sensitivity of noise… I wonder if it’s connected to a piezo on its secondary side… not sure anymore if it’s in the same core.. it could be a manner to isolate the sensor so the cell can work floating

I came up with an idea for this hydrophone that is simply a piezo made to be water prof by using some transformer varnish and place inside a metal enclosure to make it directional and less prone to interference… may not last forever by may be able to capture the signal.. there is specialized equipment for that… if in your good heart you are thankful for this information and you can buy one and send to me… please let’s waste less time…

I’m not sure if water will break but it will indeed resonate like hell and we are going to have lot of fun!

Resume the frequency will be tuned by positioning the electrodes and sensor… tuned to maximum amplitude

The correct frequency can be found changing the frequency manually to find the highest amplitude of the signal for that position later the phase is matched to get the maximum amplitude possible

Seems like a good plan? Anyone willing to help?

Ways to help:

Send money haha
Send hydrophone
To to my YouTube and watch all the videos from start to end, like comment and follow and share (watching entirely is important otherwise you actually make my algorithm worse as it won’t be detected as relevant if you only watch a few minutes from a long video… please this is not so hard next to what we’ve done in this last 17 years of hard work and spending time and money already gone that was really hard to get

See the image in attachment

Meyer cited this patent on the pll patent… it’s an explanation of the pll patent and how the feedback works

The current sensor detects when current drops at very high Q factor transducer and than it feedback to the es

As you see the current is feed from a center tap from the feedback transformer!!!!! Just as I was imagining some hour ago before reading it!
