Yes, I agree, go for it. Often it's the designer, not just the design, that is important, especially in the East. Go for it, you  might be able to make some big money, or at least a fairly big one-time hit that will get you past your current hard times.

I am so jealous.... but your hard work is paying off, congratulations and good for you.

@ TinselKoala

I'm not trying to take away anything from what Gadgetmall has come up with, but in the spirit of open source projects....

"but your hard work is paying off"

I think that it was a group effort that brought change to this JT thread as far as improving circuits, there has been many contributions along the way that made this possible for Gadgetmall,is all that I'm trying to say, and I wish him the best in his endeavor to make this public.

There's no way a patent could be granted as such on this device unless I'm mistaken.  And as such, being an open project my only wish is that Gdgetmall makes a hefty profit and that the rest be invested in free energy research in return, although I'm not sure how that could be done logistically, is there a free energy group ready to receive and dispurse the funds in place yet?

Regards,

Hey, if he buys me a beer someday, that will be more than enough to repay me for my tiny contribution of building one of his circuits and confirming it works !!
He doesn't have to patent anything to make a profit from his work. He's the one that packaged the system nicely and showed that it didn't have to be a sprawling bunch of clipleads to work and be interesting. The companies who want to use his ideas... even if they are just nicely packaged versions of a group effort.... will be willing to make it worth his time, even if only as a "broker" or finder of the tech for them. Since I'm not heavily invested it's easy for me to say that he owes no one anything; others might feel differently ....  but I still say "excellent" and "go for it"!

Nice Buit.
I buld similar to your mini SJR 3, but running with 12 V. I took inductor from dead cfl circuit. I will try to run on 1.5 V like yours.

Hi,

Here is my version of the LaserSaber Joule Ringer CrossOver oscillator.

I could not get it to start oscillate without the resistor, but when it started up, I could remove the resistor.
My output goes to a 230VAC 3 Watt LED lamp. When the 3 Watt LED lamp has full brightness, then my
power supply did display 8.0 Volt @ 0,08 Ampere. If I tried to increase voltage above the 8 Volt, then
the brightness in the LED lamp did not increase. I did measure 47 VAC (average) over the LED lamp
wires when the lamp did reach full brightness. My transistor (the power NPN) did heat up just a very little
when the circuit was running. Already at 5 VDC @ 0,07 Ampere, the LED lamp has enough brightness
(very close to full) to read a book.

Thank you LaserSaber for open source such a nice circuit.

Added 1, seems like a wide band oscillator. Main RF energy at approx. 255KHz.

Added 2, estimated run time from a 9 Volt battery is approx. 9 hours with LED lamp at close to full brightness.

Added 3, current usage at 12 VDC was 0,1 Ampere. The LED lamp did not have any more brightness than at 8 VDC.

Groundloop.

Hi Alex . good to see you. Thank you for Showing your circuit . he is using a cap again and you know i will try that one when i get time. I have yet to see a cap drive a large Led lamp from an electrolytic .

To all who actually work here. If anything comes of this i would never forget my friends and fellow experimenters and anyone who gave me inspiration to not only Us the actually ones who take it a step at a time with our hands but also from all the people that said it's just a blocking oscillator and no that won't work and i can't get it to work and your mod don't work  and 1000's of hours of blind experimenting ,prodding probing measuring circuits wrong ,getting humiliated and picked on picked on in a round about way .

It is Thanksgiving and don't forget who you are that i am thankful for .

Tk. You know i would get that beer for ya . a case or keg. Right now though me and my daughter don't even have a place to go for thanks giving dinner or afford a Turkey so we will probably cook burgers on the grill

Happy Thanksgiving eve everyone

BTW nannygoat . That's my circuits mod  in there and the way i did it was the way I Did it and no one else at that time. Build you own PocketPower+ by coping me or buy it from china if You want one because i told and showed everyone how to make them better in more than one thread many times over .

Lasersaber gave me a few nice comments on how I inspired him and He also inspires me .
