Thanks for posting this.Good stuff.

It appears to be the best set up to date based on what I believe is the ideal schematic as presented by Don.I see the tank circuit which is vital to resonant transformer operation.

Cheers!

Thanks

Many thanks to a.king21 and to qwekw for the useful info.
Also thanks go as well to the chinese guys for this simple circuit show and performamce.

Hi ewizard

Thanks for your reply
here is the circuit i need advice on

Thanks

Here simple circuit, that coupling back EMF. In small voltages of back EMF you probarly not get overunity, only maybe in big voltages (200-1000 V)/

According to Don, you should be able to put 12 volts on an L2 and extract 12 amps out.
The conditions that need to be satisfied to get overunity includes:

(a.) system MUST be at resonance.
(b.) L2 must be wound a certain way.
(c.) core material helps, eg: metglas, ferrite etc.

Car alternators give 12 volts @ over 50 amps I think.So frequency is also a factor.Hence low voltage pulsed at high frequencies or High voltages pulsed at low frequecies or have it all,hi voltages at high frequecies.His formula illustrated these.

The case in reality might be different but my thoughts anyway.

how to keep all commercial drug adds from setting up threads on this energetic forum

Hello @ all,

who knows what to do to keep all those drug adds from setting up sales adds by means of making threads on this energetic forum? need to have editor or admin block them from this site!

Clarence,

as always, mike.

The Royer oscillator is notorious for pulling alot of amps,


edit: it did not work can someone tell me why,

Dear Dave45.

With my limited knowledge of electronics I would say the two capacitors are blocking the DC input into the primary coils. I like the idea though!!

It might be an interesting test, if you have built the circuit, to try a jumper across those capacitors and remove them once the oscillations have started.

But my gut tells me that it will cease to oscillate!!

Cheers Grum.

Hi Clarence, one of my pet hates as well, they use crafty titles to try to
evade immediate detection at times and some could lead to viral infected sites.

It is up to the site admins, In my opinion to combat it would require a more
rigorous registering process where the person must wait for some time and
correspond with an admin to gain membership.

In a situation where just anyone can sign up we get multiple accounts
violators, people making multiple accounts to promote their own scams
and fake claims to waste as many peoples time as possible, also to
allow them to abuse people with a "dispensable" account. As well
as spam and click revenue posts. Surely it must be easier work for the mods
to prevent it than to have to remove all the posts and just watch all the
upset it causes.

Stricter registration process is the answer, maybe also after joining a person
cannot make a thread until the member has made a certain amount of posts
contributing to other threads, or a certain period has passed, just say two
weeks or even one week and five posts. Some sites require over 20 posts and
months of membership before threads can be started by a new member.

However that would limit the membership numbers which would seem to be a
bottom line in some way. Only people serious in their projects or opinions
would take the effort, new membership would drop. But it would keep a lot of
loons from joining the site to begin with'

This has been suggested before and with a quite well thought out plan by
people savvy in web site stuff. However, unless site management sees it as
beneficial it won't happen, can't blame them for that. People do what is best
for them, it may cause them too many problems or something I really do not
know the finer working of the issues. I just think a filter process would help
with the spammers.

Cheers

I so disagree....
Falstad royer sim
If you mouse over the meters the part lights up it's on.... optimized for 24V input

Make real circuit and prove simulation?

Sorry, there are lots of wires and can't see circuit and caps there, do you have another video with more clear circuit on camera?

*shrug* this is before that coil I think

https://www.youtube.com/watch?v=F2oSxTWCIUc

it's basically a 2.2nf cap, which is about the same as the parasitic capacitance of the coil is...

Adjusting the voltage divider for the input voltage reduces current draw... that's where most of it is lost.

then making sure the inductor on the power supply is large enough so it works to choke the current to the coils... seems to have to be coil inductance squared.

So you have ZVS driver ZVS (Mazilli) Driver | Adam's Science Website (aka Mazilli) but
not http://i163.photobucket.com/albums/t...psde17a671.png

And I was asking for proof build of http://i163.photobucket.com/albums/t...psde17a671.png to show it working.

Also in your setup in realy needs soldering to clean normal circuit and getting rid of all those crocodile wires so it would make much less trouble with reconnecting it all back again...
