valyonpz is still alive! hooray
he put up new detailed video on vic  build and reason for air gap in core

 "     https://www.youtube.com/watch?v=5pctHhgaJVw#ws    "

https://www.youtube.com/watch?v=Ro0uviOdnuQ#ws

this is the bias, is this bias the same as a amplifirer?

sorry I cant answer about bias/amplifier, I don't have enough understanding of the circuit.
Looks like some transistors to drive the mosfet

valyonpz has posted another video, some good information on vic coil resonance and similarity to resonant transformer/tesla coil
"     https://www.youtube.com/watch?v=WJ6ADtr7MoQ#noexternalembed-ws    "

good tests. i have done similar this last 2-3 weeks.

valyonpz gives link on the video to translation of  japanese wiki page on tesla coil ( differernt to western wiki),
https://translate.google.bg/translate?sl=auto&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Fja.wikipedia.org%2Fwiki%2F%E3%83%86%E3%82%B9%E3%83%A9%E3%82%B3%E3%82%A4%E3%83%AB%23&edit-text=&act=url

its quite interesting article, from what I can understand the spark gap is used to give rise to a broadband of frequencies, some of which will resonate ( I"m guessing multiple frequencies will resonant, many harmonics of primary resonant frequency I guess), an interesting way to generate frequencies without a modern day freq. gen.

It also list some devices which use telsa style resonance systems in modern applications, one being the lcd backlight devices ( which is mentioned in another thread on this forum)
http://open-source-energy.org/?topic=2005.0
There is a pin on the ccfl boards to vary frequency, though is not straight forward to use that pin,
it may well be possible to modify a ccfl board for use in hho meyer style, but I think might be a complex undertaking to achieve it.

made mistake: pwm adjust on ccfl backlight boards not freq,
but... if can identify the resonant capacitor on the board, replacing it with similar capacitance water cell might get some results if they auto adjust resonant frequency.

i've been searching for stainless steel winding wire, have found some cheap source of stainless
wire but unknown what type of stainless is used, seems to have some sort of coating on it.
Might be ok for experimenting ( its used for making necklaces)

just a thought:
IF water acts as a capacitor when polarised

An inrush of current occurs when a capacitor is first charged often seen as a spark when various appiances are plugged into power.
So if water is polarised  it should be possible to see an inrush of current when power is applied.
( assuming it acts as a true capacitor)
I have no idea how this might be of relevance to meyers system, though I remember reading on Naudins website, he modified his experiments so that water acted as a true capacitor ( I didn't understand how he achieved this).
Practical use?
lets say you use neodymium magnets to polarise water ( example round with hole type neos with water in plastic tube flowing through the middle of the neos), an inrush of current via electrodes might be detectable and an indictator that the water has been polarised.
The direction of polarisation ( in 3d space) and location of the electrodes might be important.
just some thoughts

i've just recieved some of the stainless wire in a previous post,
description:
ohmns per metre ( very approx) 9ohm/m
its not attracted to very strong neodymium magnets
its made of 7 strands of very thin dia ss wire twisted together to make a dia of 0.38mm
it has a plastic coating acting as insulator ( very thin coating) but does insulate the wire well.
It came on a spool of 100m, spool is approx 10cm inner dia ( guesstimate) and 2cm wide, inductance of the 100m spool is 22millihenries ( resistance 1kohm) without iron core.
what you guys think? is it useable?

I see stan was using 0.004ga ( 4thousands of an inch?) for ss wire.
that would be o.1mm, the wire i've sourced is 0.38, about 4 times thicker,
I will give it a go,
just a note also valyonpz posted his complete schematic in last video he posted
which i've attached ( hope he doesn't mind!!)
I think its worthwhile posting it so its not lost.
also hoping valyonpz will continue to post videos, he seems very far advanced with his
research and willing to share it. Much appreciated Valyonpz if you happen to read this.

on valyonpz circuit above, he has a variable pot ( 50kohmn) on pin 9 of the 4046 chip,
he has marked it as 'resonance' , it looks like he has some form of PLL on this circuit,
I think this is a very advanced design, can anyone elaborate give insight into the functioning of
this 4046 chip and how the PLL operates?

brettly, I used 4046 in 2010 and it was difficult to read the manual and understand how the totem pole phase shift charging works.
4046 has 2 different modes for phase shift detection and to make things worse there are 2 different manufacturers and one of them supports 2 modes and the other supports 3 phase shift modes. so there are 2 different manuals :idea:

that was the point when i did not get it run and if there would not have been a nice supportive and patient guy named Techstatic at energeticforum it would not have run. after it ran in freedom circuit i had to put it to the bin because gating didn´t work with phase shift.

if you like you can follow the conversation from 2010 starting at energeticforum and after Aaron banned me we continued our work at hereticalbuilders and got it run so far (without gating of course)

without getting into detail: bit banging of totem pole means that pulse output can be adjusted by voltage, voltage controlled frequency. the phase shift is fixed to 90° (if I remember correct) and some kind of xor logic creates pulses from a tri-state pin into a charging capacitor. this capacitor integrates the pulses (some hi, some low and vice versa) and so creates a voltage integral which is fed into the frequency controlling voltage.

of course with a certain capacitor that only works in a limited range and so you have some switches and pots you have to adjust to stay in the frequency ballpark.

stan meyer extended that funciton by using analog switches and was able to switch to a 555 output creating a triangle signal and that way he was able to realize frequency sweep in the audio range. once 4046 detected phase lock analog switches switched to the charging capaciter and frequency stayed regulated in the ballpark (of course without gating).

gating does and did not work because stopping pulse output discharges the capacitor and in consequence frequency changes to a range outside the resonance ballpark and the system has to restart swinging in to resonance. if there are only 10 active pulses before gating and it needs 8 of them to reach resonant frequency the system has failed.

hope that helps.


PS: this sweep and lock in is a function I´m integrating into PGen 2.0 right now. normal pll lock and variable phase shifts are implemented for more than a year now and are the reason why i started to program PGen 2.0 product family. you won´t find that anywhere else, it´s unique.

thanks very much gunther, that helps my understanding very much.
I have read some parts of the threads you mentioned, very good info.

valyonpz has posted new video showing replication of stephen meyer waveform,
using stans vic, he's also included some mods to his circuit...very good of him to share
his hard work
"    https://www.youtube.com/watch?v=tOJkCV9wcs4#ws    "

valyonpz has uploaded another video on waveform at primary.
Can anyone comment on his results I haven't seen this reported on previously? He shows a voltage doubling on primary side coil where a spike occurs, the spike has a high freq in the mhz range, he also shows the difference of the spike with and without resistor in parallel to the primary coil ( seems stan used resistor in parallel)
I'm not sure which of his scope shots near end of video is with/without the resistor, but some very interesting results.

little at a time. thanks for keeping us updated.

two more vids from valyonpz
 ' https://www.youtube.com/watch?v=UxXm7Nz_LL8#ws '
shows excellent details of step charging effect and compares stan and stephen meyers graphical description of step charging, also function of diode across coils.
 ' https://www.youtube.com/watch?v=m5M60dwKRUo#ws '
shows another method to produce step charge ( from russian forum info/idea)
( note had to modify this post valyonpz edited his vid)
this is very interesting method to achieve step charge, it uses only one winding, diodes and capacitors to achieve same effect. Well worth watching.

note that on valyonpz circuit diagrams linked to his latest vids he has been further enhancing
his circuit, he has now got rid of the 566 chip, and gone back to two 555's, very nice work,
the 566 chips are damn expensive.Also three 4017 chips, I haven't looked up their function as yet.
Can anyone enlighten me? He posts his latest circuit dia here:

Hope he doesn't mind me  posting his info on here, Valyonpz if you read this thread, please send me a message.

replicating 8xa waveforms

Sure would like to see a baseline DC brute force comparison showing power and production rate.  As yet, I'm not convinced anything special is going on there.  Until someone has a true looper, all we can do is push forward a little bit at a time.

I agree a comparison of amount of gas produced by straight dc compared to valyonpz circuits would be most interesting. Maybe he will read this thread. I think the work he is doing independtly is quite advanced. I came across an early post by him in another forum and his work has progressed remarkably over the years. I think he is leaving a valuable resource via his videos.

I came across a youtube video last night which outlined how to calculate how much h2 gas is required to run a car ( based on btu calculations), the author came up with a simple formula:
10,470/mpg = x L/min  of H2 gas
example
a 30mpg on petrol car would require
10,470/30=349 L/min of H2

https://www.youtube.com/watch?v=7qzrI20VPCw#

The maths looks sound but there are a couple of variables not considered in the video
1. burn rate of H2 is different to petrol
2. mpg rate will be same using petrol or hydrogen
3. HHO is used generally, rather than straight H2

Looking at point 1:
Burn rate of h2 is about 5.5 times petrol since Stan was adding combusted exhaust back into the hho stream to lower the burn rate, I would assume
that would mean less H2 ( as hho) is being used than pure H2. That would lower the L/min
required. Would it lower the L/min by a factor of 5.5?
So instead 349L/min in example above ( divide by 5.5) gives  63L/min?
Point 2: I have no knowledge on this, I would be guessing that hho is more efficient due to
smaller molecule size .
Point 3: I have no idea how using hho compared with straight H2 will effect amount of gas required

For certain, if you try to get this production rate of HHO via brute force, it's a dead end.  So...

You must lower the flow rate required.  To do this you need to increase how energetic the gas is, then mix it with air.  If you can do this while decreasing input power needed to split the water, you're all set.

Lots of work yet to do.
