  //Possible improvement: Sometimes the decimals of the floating point number are slightly different
  //For example, this is the floating point number: 87073.37, but the extracted decimal part is 36.
  //This can happen because I do not round the number. So 87073.37 can be 87073.3650212125... which is 87073.37 when it is rounded
  //But when I do the above operation, the two digits extracted are 3 and 6. For "more accuracy", float must be rounded first.

  //At this point we know the following things:
  //1.) we manually set the number of decimal digits to 2. it will be two digits whatever we do.

now it works from 0 to 1000 with rotary encoder… it has acceleation in the encoder making it wonderfull for a good range… now implementing the increments for higher precision manual tuning

i thought of making it possible to change the parameters without wifi… just saving on epprom

the idea is to use one long 5s  click to set the config mode than pressing the button change the function to change the param with the encoder

A phase
B band width
C center frequency
D Wave form
E Gate duty cycle
F Frequency manual change
G Gate Frequency
H
I current sensor
J magnetic field
K don’t display
L magnetic field
M and N don’t display well
O lambda  display
P  pressure limit
Q don’t display well I guess
R  Rpm control or indication
S sweep frequency select
T Air time
U exhaust time
V = U and W and X = H don’t display well I guess
Y injector min time
Y2 injector max time
Z hydrogen /oxygen time
PA gas processor phase
Pb band
Pc center f
Pd wave f
Pe gate duty
Pf freq
Pg gate freq
Pi current sensor



Also the wave form can be selected… maybe also a quick start stop would be nice too…

This is how I live since 2006 where I started this

What if Meyer was still alive? How would he have done it?
« Reply #81 on: March 25, 2023, 04:20:01 am »
I had a nice idea of how to get the pll possibility to work analog too however making in a modern way … how would Stan make it if he was here today? With present technology?

https://www.analog.com/en/analog-dialogue/articles/programmable-amplifiers-use-digital-potentiometers.html

Well basically there is this chips ad523x that are basically digital potentiometers

They can be used as the resistors in the filter and R1 and R2 of the pll this makes things easy to change the range of the frequency, ability to save different configurations all this controlled by the same esp32 via spi

The ad9833 also is controlled by spi…

I’m not sure if is totally needed to have the pll to work in analog mode too… from what I see the esp may be able to have a very high precision in current however I’m afraid the 12bit adc can be a little noisy and that I could maybe create instability jitter digital noise in the vco part… maybe I’m over thinking it…  12 bit gives 4000 points… so I imagine it can have around 1hz resolution for a 5khz if the band is around 5 kHz

However it increase if the range is reduced

The analog mode would go beyond that

I believe other controller could be used perhaps one even faster and with maybe 16 or even 24 bit this would improve the resolution possible

What is your opinion?  Any one here did something like it? Any experience on that? I never used esp32 adc only esp8266 one


Esp32 has 80Mhz clock so I found it can be used to compare the phases with huge precision! By doing this the filter can be set also digitally… so no problem with bits..  I think it can work up to a megahertz if all this is correct

The ad9833 is 50Mhz connection to the esp via spi so it seems no bottlenecks for the working frequency… maybe it’s not even required I just decided to use it to make sure the controller won’t be changing the frequency while do other operations although is a two core controller

So basically I’m reducing it to few parts

Power supply

Controller

8digit display

Frequency module

Encoder

Current sensor

Bnc input and output connectors

Amplifier output 400w 2 channel (thanks again to Steve for the help getting it here)

For the feedback part I’m going to add two inputs

Although apparently any phase delay caused in one of the signals could be software compensated

Basically all that will be needed is the amplifier for the feedback and interface with the 3,3 v input of the esp

And of course the programming for all this

Gpt is helping on that some

I’m going to give the code for this only to those who contributed with me along this years like Steve and very few others…

It’s a lot of work and I want to compensate those who showed support with my hard high tech  work

This include those who send me parts and send donations…

I’m trying to make it simple so anyone can build it with just few parts

Also the cell must be though in to be produced easily and i will get into that later

Stan complete system will involve

Power supply batteries alternator

Pll + feedback

Pressure sensor

Vic

Cell

Water reservoir

Filter

Pump

User input ( accelerator)  or level of demand of energy for automated production for ex for on demand production

GMS as increase injector time —>>>> gate

gas processor

Vic for gas processor

Combustion engine

Alternator

Exhaust air treatment


Depending on how the things are connected I guess is possible to run all this from the esp32 or maybe it will need a second or third controller too

At least the pressure must go to the pll circuit too for safety reasons I think also the accelerator is possible to use with it

Than this same accelerator could ne connected to a second controller that is the pll for the gas processor or simply connect bothe controlers to each other via serial tx rx connection

So the second pll will work similarly as the first however the frequency may be lower since air is lower frequency than water

It’s possible to make all this with same encoder and display just sending the commands and getting the values to display thru serial

GMS need to mix exhaust air and the gas so 3 outputs for solenoids … 4 outputs for injectors, 1 input for engine timing, 1 input for lambda oxygen feedback

The outputs can be combined with one chip that multiplexes the output this can be cascaded so it expand the outputs of the esp for example if necessary Im using one of this chips in my CNC machine under build  for that reason

Resonance or anti resonance?
« Reply #82 on: March 25, 2023, 09:27:24 am »
I used the gpt to calculate the resonance of a cell having 20cm2 with 1,7 mm flat plates with water

It resulted 7,5 kHz

It gave a capacitance of almost 1nf and the inductance it took off from the water molecules mass!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I found also something new!!!

At anti resonance also the current will be in phase just like at resonance however it will be on the minimum and not at the maximum

It occur at frequency usually higher than the resonance but is not possible to calculate directly

However knowing this is all about adding a current sensing that only allow locking after its under a certain value

The sweep is from low to high so it’s always going to face first the resonance and than magically current will drop to zero at anti resonance…

I’m not sure if Meyer did just this and it worked or if an alternating magnetic field and a modification inside the cell will be required to activate this mode but certainly is possible!!!!!


And I’m going to find how!!!!

If that is correct will be possible to calsculate for the gas processor too

If we could form a team I would like to have one Pearson working at each part so we could advance on the research faster

Something like someone work at the code, one work at the gas processor one at the cell and one at the system for injecting the gas…

The gas processor may be easier than the cell to put to work!!! The result may be highly ionized gas that may change a flame behavior if feed together with some methane whatever… but basically the circuit is the same and is more of an ideal component!!!


I could help with calculations and testing of cell and gas processor too as I have many things here…


Or All could sit build everything and keep to it self hahaha


It

Is incredible how much info I put together this month

Sebosfato team invitation
« Reply #83 on: March 29, 2023, 11:20:23 am »
I decided to share the system I’m building only with selected people who believe we can really make this thing work and possibly change the world in a better way

I’m developing a manner where I can share with you and all can contribute with abilities and money

Time is very precious for me now specially because I’m having a hard time making my business grow and so I know how much my time worth and that’s exactly why I want to share this who those that are talented and really interested only.

So I’m going to invite you to pay a join fee that is going to just get in the team I thought 50 euro could be a good starting point

If you don’t have the money and still want to get in the team introduce yourself and prove your worth the time I will spend with you


I’m creating a nice box that is going to house the wfc pll control and also the Gas processor and GMS system

It will all be controlled by few buttons and few displays… and leds

It will also have a Wi-Fi interface

The system will be updated by Wi-Fi and will only work with the chips I register in my code so it will be impossible to crack it or copy to other controller

So I’m going to share the plans for the box for a fee of 100 dollars

If you want me to build the box for you it will cost around 500 dollars and will be very charming

The plans for the feedback circuit and coil and resistor I will share for 50 dollars

And if anyone want it well designed like mine in a fancy metálic box bnc connectors and dc connectors and all ready to go it will cost 200

The code I will share for a 100 dollar anual fee so you can have updates for one year… if the system is already working and you don’t need more updates will be one time fee only

The code is the only part I won’t share for now as it’s unique and is the hardest part until now as it takes countless hours to do

With the plans you may find all the parts on eBay or Amazon or AliExpress and may be able to put it all together with my instructions and help

The coils former design I will share for free with the team and if tou want to buy same cores as me I can make the bridge with Thornton.com.br

Of course I will also share the design formulas and all I’m using with all detail possible

Hope you got my message


Ah last but not least

As soon as I get it to work I’m going to invite the team for coming here in Brazil to see it working before we anyone else

And if by any chance it won’t work you can sell this equipment as a ultrasonic welding power supply

Go check how much it cost! 

I think is a win win chance for everyone

I remember I will select the team and as the team get bigger team members will have a great deal of responsibility at least for keeping the info safe in the case anything happen to me or anyone

The selection will be based on your capabilities and how you can contribute so there is going to be a 15 min video call so we can meet each other and I will have to see you are a real person not a spy haha it’s all about time.. I just want to save the team time and focus to make it fast

If you don’t get accepted in the team don’t worry just sit and wait like you probably did all this time. Soon you get your world changed just send us the good vibrations and if you can donate!

Frequently asked questions

No the plans are not for sale if you are not in the team no one can give you access to it if the anyone in the team does it their balls will be smashed

No info should get out of the team regarding the cell geometry so don’t even ask about

No the pll box is not for sale too… I’m not for sale neither you… things jus cost money and so the team will have to contribute to see the community growing specially because we are so few

No! Im not trying to scam anyone I even tell you a use you can do for the system if it don’t work with water splitting but truly I believe is what it takes

No you won’t convince me of stopping

No I’m not afraid of spending my time and money to build a dream

No I’m not tired or something

Yes! It’s going to work!

No I won’t give any valuable info free anymore as they costed my a life and much work and lot of fun of my face to learn and develop

If you want it for free wait and watch… if the world really change maybe one day you get it for free but if you keep on this atitude probably will starve soon as the world goes..

Hope you all have a wonderful day!

Don’t wast time

If you want get into the team do it now… this is not a long term offer

I’m going to order the boards from China already this week… if you are in you are in let me know

I’m going to make a plataforma so we can share this info out of the servers of the big companies

The feedback boards I’m going to charge 100 dollar it has 2 bnc connectors outputs power supply input and output and connection for the current transformer and to the resistor

The pll box will have double bnc inputs so you can interface with oscilloscope I may make a video showing it working this week

Hope you have the best week in your life

Also there is going to be private videos on YouTube only specific members can have access

Levels of access are

Team member General videos and updates on the stage of technology

Who got the access to the plans of pll will get another section with videos related to it

And who get the feedback plans will get access to videos related to the feedback

Hope it’s fair for everyone… if you live in a poor or find yourself in a poverty condition make me know if maybe we can help you have the boards necessary for you for a more reasonable price… the true is that this is all very cheap if you compare with today equipments and technology but as many people we get together it can get even lighter for the pockets of everyone including mine…


I spend in this tech up to today more than 100 thousand euros along this 17 years easily and this is how much I believe

If you want to walk next me please join the team.. the worst thing that can happen is you learn something

Your silence for me is a measurement of how I’m wasting my time sharing with bunch of unknowns

If you want to get in the team manifest yourself… if anyone want to get in later there’s not going to be this possibility…

Don’t waste you time and money anymore as a forever alone individual in you isolate lab… let’s get together talk, build test results we can compare agains each otherzzz

Last call

For the number of reads this post had I guess I’m doing the right thing getting away from so many unknown people

Double frequency wonder
« Reply #85 on: March 31, 2023, 02:18:03 am »
Have you ask yourself why Meyer consider that the frequency double?

And why he had frequency dividers in his boards?

How to compare apples pies with peach  juices?

Or how to use lemons to make a apple juice?

Base line capacitors block dc … filter high frequency if in parallel and pass it in series

Coils isolate two circuits allowing to interact with each other…

Why the cell resistance would increase?

Would the junction of the applied dc electromagnetic induction Lorentz force create a alternating spiraling out electric field?

In the very first time I got my hand on a flyback I made an experiment where I rolled the inner electrode in Mylar and inserted into the outer tube than pulsed with very high voltage and at a certain frequency there was water vapor coming right thru the middle of the Mylar worked like a gêiser geizer don’t know how spell it

When you get many thing in one hand and nothing at the other what you do?

How you compare a full wave bridge signal? To a square wave?

Enigma for the weekend

Is there a coil in the system that will show this double frequency?

How much the digital pll will make all this easier?

How much knowing what to look for make difference?

And in that case what must be in phase in relation to it?

Complex answers for simple questions…
