I still need someone to make a connection diagram with the flyback transformer I showed on previous page in order to integrate it into the overall schematic. I really don't want to make any mistakes and risk damaging the flyback coil. So if anyone has a step by step instruction on how to modify the flyback and connect it into the diagram, this would help me and others.

our main variable here is the flyback tx.

You need to use a meter to find the windings that are not connected to the secondary .
getting access to  the hv secodary will be a problem for most modern flyback transformers and will be differnt on a  case by case basis.

There will be one pin that is more distance away from the others that is the hv secondary ground.

Plasma globe transformers seem to be worth trying so that some kind of standard can be established ..but in any case you must tune your flyback as described quite well in the video. This is a key point, made well in the second video .

This is a process like tuning a musical instrument . The  sections must be in a kind harmony with each other .

It will get very interesting when we all get to the stage of sending a tiny amount of output back to the input driver in the correct phase..later ...

only  older tv sets will have the right flyback . In australia there are still a few old "rank arena" (wooden cabinet) brand ctv's being thrown out but most all of them are past it now...in my years i never replaced the fbt in one. But they would be correct as they have no built in rectifier.

It will be important that we can solve the flyback problem for everyone without using a junkyard transformer. I hope the Main team might help with trying with a more commonly available component like a cheap plasm globe transformer. Or even a car ignition coil ? or something that everyone can get hold of . I know that it is very unlikely that we can buy the flyback type  in the video.

The current capability of the hv  should not be a problem if the tuning is correct .(acording to SM)

@t1000
how much hvac was necessary to achieve  operation?

@energia09
This is a global effort and the times people can be together at once are difficult to meet and different people have limited time.
The u tube videos are doing a fine job and the lag problem that many have is not such a problem. I personally have a  slow connection that drops in and out and makes skype useless. It still a good idea in principle, but i suggest we keep this path , it is working fine .


Thanks again guys for  showing us all a correct path and method.

Thanks to all for staying on topic , this effort is surely in the right direction.

@Goat,
Thank you for converting the circuit from black to white background, it printed out here nicely.

@electricme

You're welcome, but please pay attention to the pnp npn orientation in the schematic, they are not correct as was pointed out by xenomorphlabs and confirmed by T-1000 in post 7850 and 7851 at http://www.overunity.com/index.php?topic=7679.msg303091#msg303091

Attached is the correct transistor orientation.

hope this isn't off topic but i noticed you guys are looking for flybacks with no diodes..
this units have two kinds of diodeless flybacks in them and i always can pick one up in a goodwill shop for 4-9 dollars..
hope this helps..

@Kooler...My thoughts exactly...where can everyone get the right kind of flyback transformer worldwide?  Nearly impossible....As Mannix  mentioned the main variable here is the flyback transformer so I guess it's possible that the flyback you posted would be as good as any other...the biggest hurdle I see is that you have to get all the components correct and in resonance as posted by Stivep in the video...It's going to be hard for everyone to come together with the most common components that everyone can easily get in order to replicate this circuit...I myself am not in a position to try it yet but thanks for your input 

Regards,
Paul

it's all about recycle, nothing more. back to my pop corn.

Well done on the progress. I've been watching from the start however I have no idea where to start! 526 pages!

I advise you to read from 500 ..

Team.
You must go two way simultaneously. Build custom made flyback from widely available ferrite core, and also show how a various flybacks can be adjusted to resonance for working circuit.Then combine those two methods (show how custom made flyback is adjusted to resonance). That way everybody could replicate your circuit.

i have a Flyback from an Old TV, a flyback from a plasma Globe, and i make a custom flyback now

Thanks for the link, i have the chance to get one from there.
The biggest problem in identifying the right flyback is that they
are commonly not advertised with their turns ratio or secondary
voltage rating.
Most plastic encased flybacks are filled up with epoxy resin, so
it's nearly impossible to remove the rectifiers from there.
T-1000 uses a ТВС-110Л (pretty common in russia) :
http://skywarrior.flyback.org.ru/tvs.htm

Flybacks usually have secondary voltages of 8.5kv, 9kv, 1kv(very rare), 6kv and 25kv (rare too). So the 25kV ones are considered rare.
Best indicator of a 25kV one is probably if the secondary is a big chunky donut rather than a little cylinder.
You can of course always raise the primary voltage to get to 25kV if the transformer can handle it.

In the list that Tonyx made for example the first flyback has a turns ratio of 102.
So when you drive the primary with 220 Volt you get 22 kV out (if you manage to remove the tripler cascade that is)
