and this one from valyonpz might be related to the pulsing circuit using optocouplers as in stans memo

and heres a pic of stans control unit showing steam resonator control board
( which appears identical to the resonant cavity control sections)...suggesting either it uses same pulse circuit for steam res as the resonant cavities ( hho tubes) or he just used the same control panel for steam res for convenience ( I would guess its using same pulse circuit as stans work was very clean/finished design).

one more pic showing two connections for steam resonator on the resonant cavity,

so is it possible to reverse engineer/replicate stans water heater from this information?
Is there enough information to do it?
I realise their are two videos on the net showing replications ( waterenergy1 and irondmax) but seems no detailed information with the vids that would aid reverse engineering).
There are other threads on other forums on this topic but seems no-one has given a replicatible circuit. I've included valyonpz circuits as they the only ones I've been able to find that are related to replicating what evidence there is of stans device.

there is another view of steam res switching board with coil attached

in this pic I've added some dots which represent unknown connections
2 purple dots = two earthing? wires been cut
2 red dots = two thick red wires cut
4 green dots = transistor earth wires been cut
1 red dot (bottom of fuse) /one black dot ( bottom right in pic)= wire connections unknown

pic attached reverse engineered circuit someone? posted, some missing bits included
fuse and two red wires unattached at top of fuse
bottom  of fuse red wire not attached
4 green earths not attached to anything
2 purple dots earth? wires cut
The rectifying diode suggests an ac current was being changed to dc before going into the primary
( possibly from alternator three phase output?) but where was the pulsing dc being produced i.e tank circuit with resonant frequency, was that even used in this circuit?

close up view showing heatsink pad had previously been used behind the transistors,
now each transistor is just heatpaste so each has centretap connected to aluminium backplate.
Poses the question, has stan modified the circuit to be simpler after building it, which may explain the two red wires not connected to transistors or has he deliberatley removed the heatsinks to make reverse engineer more difficult?

just went back over valyonpz video
well worth watching

https://www.youtube.com/watch?v=SgpcBRbnyTE#ws
apparently the device i've been posting on, its simply the power supply for the steam resonator,
it converts 12v to 240v.............doh!
that would mean the optocoupler circuit he gives attached would be the thing to concentrate efforts on, he makes note at end of video about pulsing timing.

I think that the 12v/240v converter is also switching between coils, one coil on the other coil off,
the optocoupler driven by dual 555 circuit or similar same as the resonant cavity cells,
and bifilar? chokes also. Interesting the water bath used as earth so any time one plate is not powered. I think valyonpz may well be correct, i'm not electronics expert so maybe some other guys here can figure out circuit component parts/values so that it can be built?

The pair of transistors appear to be darlington optocouplers like these:

But the resistors in the schematic look wrong.  Maybe the circuit is entirely designed to do something else.

its definitely a h-bridge circuit ( seems they are used for dc/ac sinewave inverters and dc motor controllers)
I'm very much a novice on this, but the signal to control the transistors can have two parts, one for pwm and the other for gating? I'll do some more work on matching stans built circuit and matching it to valyonpz circuits, I think he is on the right track.

Always remember me on that circuit. Look at the hot water switch....

thnx for posting haven't seen that circuit,
the transistors ( sk3181a/sk3180) first is 40v, second one is 80v, they seem to be connected to the high voltage coil wires, if they are stepped up from 12v to 240v by 20:1 from primary to secondary they seem to be underrated for the voltage?

Hey. The circuit is in an old patent of Stanley Meyer.
You see no charging chokes or whatever.
It looks like a voltage selector, in the patent is descripted, that the hot water switch activated higher voltages.

Maybe some pre designe of the Steam Resonator.

Maybe not a converter to 120V/230V, but to 70 or 60 or something like that. The amperage would be much too high with 120V. I tried this several times.

just messing with reverse engineering stans hbridge:
put some coloured lines on these two diagrams ( and labelled the transistors in detail)
first diagram is what stan built, second picture is matching it to valyonpz h-bridge diagram
( very difficult to go any further unless the transistors are insulated from the aluminium plate that is putting all the collectors of transistors onto a common electrical connection, still plenty of mystery to solve on this one)

I came across a bit of info on daniel dontinellis website, where he posted a conversation with irondmax, where max says this device is a power supply device not for hot water, not sure if I agree, but if that is true then wasting my time trying to work it out.
Can anyone confirm if this device/coil/h-bridge is for power supply or is related to hot water heating.
I didn't keep the link on daniels site on this info above

it´s definitely no power supply. it´s made for water heating. of course it uses a power supply but amost every application needs a power supply today ;-)

this circuit serves a way to create high voltage with amp restriction out of a simple 12V car power supply. ideal for his car application.

the modus operandi is a bit similar to the bob boyce toroid 3 phase transformer where grid voltage rectified is modulated by 3 different input phase windings.
heatlocke will know.

thanks gunther that is impetus to keep going,
I've been reading stans memo 430 on the steam resonator, I will post later on some issues it raises when trying to figure out this circuit.

came across a circuit called a 'transverter' it appears very similar to  stans built part of steam resonator, also has a scope shot see bottom of this page
http://peswiki.com/index.php/Directory:Transverter

also came across this circuit

very similar to the pics amsy posted previously ( the circuit of stans that includes switch for
hot water or furnace), this would seem to confirm the circuit can switch polarity.

 i mentioned previous in this thread on daniel donatellis website it quotes max miller saying what is regarding as stans h-bridge for stream resonator is a power supply board, I found the link where is posted, if daniel or max read this can I ask if they still hold this view? It would be good to see if max miller still regards the circuit board as a power supply,
its found on this page
danieldonatelli.wix.com/backup-pocket-jy2014#!vic-circuit/c1tae
I've cut and paste the info also

 a closer look at what had been labelled as 'resistors' on an interpretation of stans board,
you can see the thick windings under the black heat shrink/plastic, so they are inductors rather than resistors, so max millers interpreation of this being a power supply board might be correct?
