I think everyone should have a burn-o-meter. Or we should all be in the same lab borrowing Russ' meter. :D
And yes, I wish there was a way we could all work together in the same lab. I'd bet we'd have something to offer the world in a very short time. Either that or we'd all have to get plastic surgery to remove the permanent smiles from our faces.

Watching Russ, I'm not sure his design is too good for HHO. I think a very short tube that expels a projectile would be more appropriate. Then you just measure the speed of the projectile to get an indication of energy.Quote from firepinto on September 23rd, 2013, 07:45 PM I think everyone should have a burn-o-meter.

I often wondered if the piston in Russ his meter would not be pulled back, get sucked back by the vacuum after the explosion.
One could make a (rubber tire) flap inside the piston, (or inside the cylinder) that opens up when the airflow reverses.

The piston did retract some, that is why he had a plastic ring on top of the piston that stayed in place at the highest point in the cylinder once the piston moved back. :cool:

[RANT]
These last few days have indeed been most educative for me, mucho kudos goes to Lamare, Farrah, HMS, Bussi, just to mention a few.
Now I have come to the point where I'm about to perform a few experiments by winding a simple enough VIC which will have a primary, secondary and the bifilar wound chokes, all having 15-20 turns 24 gauge which I will use to feed an ordinary capacitor and 10M ohm resistor in parallel and then plain just observe what happens on my oscilloscope as I change the frequency to the circuit.
Anyhow, before I do that I would like to rant about a few things that I've come to realise as a result of some of the last few days replies as seen in the threads about Meyer and his WFC.
If this is just old news so be it, I'm just sharing what I've been thinking about regarding how the VIC could work.
First of all, let's take a look at the VIC,
This is exactly how I would wind it, with the diode going from the secondary to one of the chokes, which in turn then (B+) goes to the cell anode, the cell cathode goes back to the other choke (B-) which then goes to the other end of the secondary, nothing new there.
For the longest time I just saw the diode totally disabling any transformer action as all transformers relies on AC voltages in order for them to work.
So I forced myself to believe that the waveforms from the VIC indeed looks exactly the way Meyer shows in his patents and technical briefs.
With that I also forced myself to kind of reverse engineer a plausible explanation on how it works:
The primary is pulsed with a gated PWM low DC voltage, which looks just like the way it's depicted in the patents, nothing new there.
The secondary is then induced through the core which gives it a spike kinda like shape, just as it should look like due to the nature of the inductor that which it after all is.
On the trailing edges of the primary PWM pulses the field collapses in the core, which then creates a back EMF in the secondary, which in turn then, and here's where one of my fresh insights comes into play, lowers the cathode potential in the WFC (I.E B-) either due to the secondary coil or the charging choke(s) (or both) being back EMF induced, which in turn then leads to a relative positive difference in electric potentials between B+ and B- as B- gets "pulled down" in potential in relation to the cell anode (I.E B+) as a result of this, which in turn then makes the diode forward biased once again so current flows once more from the VIC to the cell.
This also helps explain why you see double the amount of pulses on the secondary compared to the primary.
(this is of course all very abstractly speaking now, please bear with me).
To continue then you could say that for every such transition of the primary pulses, both the leading and the trailing edges, you get a step up of the voltage in the cell as the intrinsic cell capacitance charges for every such edge transition/voltage spike.
So from the start the cell voltage won't be too high, which means that the cell acts like a "standard" brute force Faradic electrolyser during the first few pulses.
As the pulsetrain continues the voltage increases in the intrinsic cell capacitor for every spike from the secondary, the Faradic brute force electrolysis increases in magnitude due to the (way too) high current that's being fed into the cell and after a while then the dielectric of the water molecules starts breaking down due to the (way too) high voltage in the cell capacitor, which leads to massive amounts of gas being released in the process.
As long as the dielectric strength of both the intrinsic cell capacitor and the gap between the anode and the cathode isn't bridged due to the high voltage between the two (anode and cathode) then the pulsed high voltage "only" serves to break down the water into hydrogen and oxygen, either by Faradic electrolysis or by fracturing (if that is indeed the correct term to use here).
IMO it also helps explaining the need for a gated pulsetrain as the cell cavity gets drained of water in the process so the intrinsic capacitance changes just because, which leads to the resonance (and I use that term very loosely here) frequency drifting away.
Last I also believe it helps explaining what i would like to call the 4 prereqs for a true Meyer WFC, namely high voltage, low current, maximum gasflow and perhaps the most important aspect of them all, which is the water stays cool during the whole process.
One thing that which could be done to enable a continous pulsetrain would be to drill holes in the outer tubes so a continous flow of water keeps the cavity filled at all times, this would also minimise the risk of having the resonance frequency drifting due to changes in the intrinsic cell capacitance.
Also, judging by the size of the WFC as seen in the video from 1990 I think that any experiment on a "real" WFC must be performed using a "full sized" cell as the intrinsic capacitance has to be quite high in order for you to be able to keep the resonance frequency in the range of say a few kHz, somewhere between 10-20 kHz for example would be preferred.
I also think that the cell array has to be attached in parallel, not in series, as that only leads to a decimation of total cell capacitance if you were to use 10 sets of tubes.
Furthermore I don't think that resonance is reached only after like 15-20 minutes as seen in some tinkerer's videos lately, that's just ridiculous, I mean just look at the Meyer cell in action, it starts producing gas the very instance he flips the switch.
Alright, enough rant for this time.
To be continued.

Some observations to your last rant:
I'd be willing to bet no one has done all this to the level of detail needed to really tear this circuit apart and fully understand its complete operation. Personally, I would like to see theoretical operation compared side-by-side with actual operation and just see if anyone really knows their stuff. The reason I say that is because a good electronics engineer should be able to re-create Stan's circuit from scratch if that is really the only way to solve the problem (generate the proper signals).
- Use a pump to keep continuous flow going so that bubbles don't alter the characteristics of the cell.
- For every scope trace you show, specifically add voltage AND current traces so we can visualize the phase offset.
- Describe every component in the circuit and how it is responsible for the particular waveforms shown on the scope.

The rant aside there's no beating real experiments, which is exactly why I'm going to wind a basic most test VIC driving a capacitor/resistor load, which I will examine on my oscilloscope.
After that then it's time to move on to a WFC so I'll learn how to tune in that one.
Then we'll see what fate has in store for me.

I salvaged an inductor from an old wrecked VFD, which has 3 windings, each 11 turn about 13-14 gauge,
Wrapped some tape around the whole thing
Wired a secondary coil all the way around it, ended up with 48 turns 24 gauge,
Sealed it once more with tape...........
.........only to realise that the chokes had to be bifilar wound
So, peel off the tape, unwind parts of the secondary so i could take away one of the coils and substitute it with 2 bifilarwound coils, 14 gauge 11 turns,
Then wind back the secondary, this time ending up getting 45 turns instead
Wrap the whole thing in tape again, this time for good (I hope.......)
Anyway, now I have a nice experimental VIC with 1 primary 11 turns 13-14 gauge, 1 secondary 45 turns 24 gauge, 1 pickup coil 11 turns 13-14 gauge and 2 bifilar wound chokes 11 turns 14 gauge.

You are kidding there aren't you EZ. You've been a member here for over a year and you are just now getting around to the VIC terminology?
I will toss something out there though that I'm still a little fuzzy about. Wasn't the sole purpose of the VIC to drive the injector system, not the WFC?

I think now that the VIC is part of the resonating circuit for the WFC.
The injector thing had its friend in the lighttunnel no? Lol (this sounds strangely gay all of a sudden, i'm not, and not that it matters but)

Alright, finally got around to do some measuring.
First things first, so to start with I checked the bandwidth on each of the coils.
As i have decided which one to use as primary that one will not be checked, only the secondaries.
First round of tests were done using 10V P-P (peak to peak) on my frequency generator, sinewave AC.
Results:
Secondary:
Pickup:
The secondary coils almost immediately maxed out (at about 100-150 Hz) and maintained the voltage all throughout the frequency sweep, so the interesting results were here when the coils started dropping in voltage.
Results:
Secondary: Started giving 40 V which then climbed at 137 kHz to 47 V only to start dropping at 154 kHz
Pickup: 12,8V, started dropping at 154 khz
Choke 1: 12,8V, started dropping at 136 kHz
Choke 2: 12,8V, started dropping at 129 kHz
Next test will be from secondary - diode - choke 1 - resistor/capacitor - choke 2 then back to secondary and see what gives.

Being a sucker for PDF's I compiled a tutorial on transformers as found here, http://www.electronics-tutorials.ws/transformer/transformer-basics.html
My PDF virtual printer gives me a 6 Mbyte file so I'm welcome to suggestions to what other options I have on virtual PDF printers, I currently use doPDFv7.
I put it all together using Word which ended up giving me a 720K file, so my virtual printer could do with an upgrade to say the least.
Anyway, it makes quite a tutorial, use it as a reference handbook if you will, it will answer most of your transformer questions
Edit: My friend google showed me Bullzip PDF printer, works like a charm.
Crunched it to 1.2 Mbyte instead, total winner

What are you going to be feeding your primary with? Just be careful as that will be seen as a short cct by a power source at low frequencies.Quote from Lynx on September 29th, 2013, 06:33 AM Alright, finally got around to do some measuring..........
It will be a simple step up converter based on switching 2 inductors which will be feeding the capacitor/resistor via diodes and the switching transistors will be triggered by monostable multivibrators which in turn will be triggered by my frequency generators (1 for gating, 1 for the operating frequency), the first one will be triggered on the leading edge of the pulse train and the second one on the trailing edge, thus simulating the double output from the VIC.
The monostable pulse generators will have a variable pulse width so I can control the output voltage from the inductors, the shorter the pulse the higher the voltage, albeit with shorter decay also as a result of that.
The opposite will be getting lower voltage but longer decay from the inductors the longer the pulse is as it switches the transistor(s).
Call it a VIC simulator if you will in the sense that it's simulating the behaviour that which I personally think that the VIC should have, that's not necessarily the same as to say that it's the correct way, that's something that will show itself during experimenting and measuring.

Lynx, I have achieved frequency doubling (so you know I'm not just talking nonsense).
See my thread here: http://www.open-source-energy.org/?tid=646&page=7 (see posts 126, 128, 135, & 138)
When you get frequency doubling you will not see 2 pulses. You will see a single pulse that is 2x the length of the pulse you put into the primary coil.
To get the effect you must have the coils connected so that they are series-aiding.
Also, I had the best results when my chokes were on a separate core from the pulse transformer.
Btw, if you want to get the same current waveform that the vic produces, use a full wave rectified ac signal. Just like Meyers early design using an autotransformer.
