Hi, Sucahyo ! Thanks for your answers ! I just recorded the video
to show you my troubles with your stingo...

To charge other battery make sure to reach 350mA output if the amp meter is put in series with charged battery. I achieve this by combining output.

My circuit consume around 500mA each at 12V.

Well, how do you combining output, because i am far away from 350 mA so far ?
What good does it make if i can run with stingo something that drains
100 or 200 or even 500 mA, if i drain for stingo 800 mA ?
I should spare with stingo energy, is not that point of stingo ?
So far i dont see benefits of stingo and of course i cant reach good results
with it...
Now i can suspect lot of things, for example transistors : so far i used bd 243
and bd 244...i could not use mje 3055 and mje 3955 , no oscillations with them and tip 32 is not obtainable here in Croatia...
I dont know what to do next...
Again problems with youtube...i just need one more reason to be tortured...
Well, as soon as youtube show some mercy i will attache videolink in my
next post...Sucahyo, dont worry about my misery ! It is just easier for me when i complain and tell whole world how i suffer, nothing too seriously
of course...I like electronics though i know i have to suffer a lot all the time,
is it not the same thing as with women ? So, you can not with them but
you can not without them too, unless you are Nikola Tesla or

Is there anyone to help me ???....NO ???...OK, then, in that case
i am going to help myself, as that song : al by myself...great song...
Well, listen to me you pour suffering guy... TRANSISTORS , YOU PUT
WRONG TRANSISTORS !!!...Do you here me ?...Once again, TRANSISTORS !!!
Ok, ok, i here you, dont yelle to me, we are going to find some other guy
to blame him for this mistake, it is always the best method : blame somebody
else for your stupidity...But, lets see, where i read in this thread about mje 3055 and mje 2955 ?...Aha, i founded it : post 37, and 39...What can i do...
I have to be more careful in future when i read posts as i am careful when i
read contracts that i put my signature on...NOw, i have charging with 40 V
and 50 mA, and draining of primary battery is only 100 mA...
FINALLY it make sense !!!...Now, i can too say with REASON :
TANK YOU VERY MUCH SUCAHYO !!!

Regads !

[cikljamas]

Aha, Cikljamas, you sucker, why dont you tell people which transistors
you use now when stuff works so well, HA ?...Ok, dont yell to me again,
i will tell them, i just forgot...Well, transistor are TIP 3055 and TIP 2955 !!!!!!!
Great job with these transistors !!!

There are two main stingo variants sucahyo has posted, one that uses TIP31/32 and one that uses TIP3055/2955. They have been used for different purposes. At this point everyone is just experimenting. I will probably experiment with trying different transistors and maybe even MOSFETs once I understand the stingo enough to be able to make calculations about it's operation.

Glad to hear you had success with the 3055/2955 combo. I have a few with that combo that work quite well.

I don't really use it for battery charging yet, I'm looking for the circuit which produces the shortest and sharpest spikes to drive a tesla coil with the intent of driving it in resonance and doing experiments related to the Magnifying Transmitter.

Yes, i already put that question, but i didnt get answer, it is about varied
stingo purposes, i am really anxious to read few the most interesting
implementations of stingo...charging battery, tesla coil...what else ?
In fact i am the most anxious to reach the point to light the neon bulb,
can anyone explain what specs. that bulb has to have, and what output
values of the stingo have to be to light that bulb...

Concerning charging role of the stingo i have even better result COP = 0,5
then with stingo, and it is solid state bedini coils with high impedance...For
example tonight, after i achieved some success with stingo i was going to
try again my old bedins ssgs coils and i did...Yes cop = 0,5 , i used six
coils and i drained 630 mA, and i have got 300 mA at the output side...
Sucahayo was right 300 mA is minimum for good charging but i think
that he said he achieve 300 mA draining about 1 A, and it is cop = 0,3, so...

[sucahyo]

Well, how do you combining output, because i am far away from 350 mA so far ?

With FWBR and I think work on all kind of radiant charger.

What good does it make if i can run with stingo something that drains 100 or 200 or even 500 mA, if i drain for stingo 800 mA ?

A radiant circuit can force more current to pass a load since radiant circuit have variable voltage. It is better than charging 12V battery with 12V battery. It may not be possible to charge 12V with 3V.

Stingo is just another radiant circuit with some different properties.

Aha, youtube showed a little bit mercy , here we are :
YouTube - stingo ignorance

Thanks for the video . It seems like your 25 scale is busted..., three of my analog meter is busted that it only show the lowest scale now.

I never put amp meter too long now. I only use it during measuring.

NOw, i have charging with 40 V and 50 mA, and draining of primary battery is only 100 mA...

Congratulation .

In that sense I am now charging 12V battery with 550V and 880 ma, that become battery voltage + 0.6V and 460ma on charged battery.

I'm looking for the circuit which produces the shortest and sharpest spikes to drive a tesla coil with the intent of driving it in resonance and doing experiments related to the Magnifying Transmitter.

Something like using high freq stingo radiant output to drive a transistor ? Should be a tough transistor though....

it is about varied stingo purposes, i am really anxious to read few the most interesting implementations of stingo...charging battery, tesla coil...what else ?

It would be the same as other radiant circuit. We can use it to make spark, to lit CFL, to do electrolysis, to do one wire lighting experiment, and we can use it for health application too .

that bulb has to have, and what output values of the stingo have to be to light that bulb...

Try the cheapest neon bulb first. And I can lit neon bulb on all coil I can make them oscillate with 12V input.

Concerning charging role of the stingo i have even better result COP = 0,5 then with stingo, and it is solid state bedini coils with high impedance...

Well it's not fair to compare 6 coil with 1 coil. But:
YouTube - COP = 69% battery charging battery

I still never publish how I get that high because I still not sure if the method is good for the battery. I call this dirty method... It show almost twice higher efficiency but may ruin a battery, cheating the actual purposes.

I don't use this dirty method on my battery swapping experiment. Dirty method is done by adding two diode and a capacitor to the FWBR and connect it to battery negative.

I am not surprise with high COP as I consider battery swapping as the only reliable test now. I will only acknowledge a system to have COP>1 if it can show it with battery swapping test.

To help with the coil. It seems the coil need to have good inductance. Here is what I just build.

I use toroid from broken computer power supply and insulated wire:


After a while I done wound it into two and a half layer:


It lit the neon brightly to the point it become slightly purple.


With two nimh in series as load the output is 240ma at 4.29V, consume 500mA at 12.35V. Second activation show output is 390mA that consume 1.2A. I don't know why I get different result ...... Maybe because the charged battery state is different. The first one have sweet spot, the second has output proportional to consumption.

The battery still cool after some minutes.


My method to check the maximum charging while the circuit still running is to use voltmeter on the charged battery, I set the potentiometer to get the highest charging voltage.

I have noticed that sometimes it is possible to drive the stingo without oscillation. I have noticed this mostly when trying to drive it with a motor as the coil. I wonder if when the output is proportional to consumption, the stingo is not oscillating? Could you still light the neon in the second activation? If so, it must be oscillating because the inductive spikes light the neon.

I notice the difference using my little oscilloscope. If the circuit is oscillating, we see the spikes. If not, the scope shows only a flat dc output.

Thanks for the info on your toroidal coil, I will wind one and test sometime soon.

Hi Sucaho interesting circuit you did nice nice. How many turns you're doing to that toroid cause it looks like a JT. The current output is AC? It looks like that neon is lighting in ac current.
Thanks

So, i doubt Sucahyo counted how many turns he have done around that
toroid...I did the same thing two days ago, and after i repaired my circuit
by changing transistors as i explained above i tried to use today that toroid
and it works very good...But i know how difficult is wound that toroid so
i am almost sure that nobody count turns number doing such a job...
Sucahyo, thanks once more !!!

Interesting. DC at radiant output? Is that while the motor running but stingo do not oscillate? NPN stays on?

How many turns you're doing to that toroid cause it looks like a JT.

Just like cikljamas said, I don't count it. I don't see it important now because I got almost the same result from similar toroid with different kind of winding. I only put attention to wound it to similar direction, female winding, clocksiwe as you see it go further.

The current output is AC? It looks like that neon is lighting in ac current.

No, the neon bulb only lit at one side = DC. Neon lit with high voltage. If DC it only lit one time at one side. If pulsed DC it will lit many time at one side. If AC it will lit both side.

radiant circuit output is pulsed DC.

I did the same thing two days ago, and after i repaired my circuit by changing transistors as i explained above i tried to use today that toroid and it works very good..

Nice .

This is what I've been looking for. Thanks! How about a few more specs? Length/gauge of wire? Whats the resistance measurement of the coil? Got any tips on how to keep winding toroids from being such a painful job?

Thanks for the other pics and circuit too!

I had a rather frustrating session with Stingo too today. Found new transformers and coils that gave nice high frequency oscillations and sharp looking pulses, but put out no power. Found a coil which wouldn't oscillate by itself, but caused my car coil's frequency to skyrocket when put in series with it. Alas, still no power payback.

My best coil is still the starter coil and I've tried shorting things out the way suggested, it increased the frequency dramatically but no power output to write home about. So I went back to my load between HV and either terminal method. I was able to charge two AAA 1.2V nimh batteries which were depleted to around 0.6V each, back up to full charge in about 2 hours with the charging battery on the other side of a capacitor and FWBR. So that was nice.

Been discovering that just about everything in the circuit effects the frequency and shape of the wave. If you tune a coil without a load and then add the load, you might as well start re-tuning again. And when your source battery voltage starts dropping...time to re-tune...if you sneeze too loud...time to re-tune...I feel your suffering, cikljamas

Length/gauge of wire?

Let say 23 awg it is the best option for me, but you can try tinier too...

Got any tips on how to keep winding toroids from being such a painful job?

You just have to yell to you enough, loud and in french like this :

I feel your suffering, cikljamas

Thanks, it helps to know i am not only sucker in the world
What to say ? When it is over (pain, frustration,whatever...)after awhile it seems like it didnt happen at all...But when it last it seems like it will never
end...So...You have to choose...Jump or stay in airplane...But i can tell you,
if you stay you will be sorry...So, jump ! But be aware : Nobody can do it
instead of yourself...Well, do not think that i think that i am more smart more
then i really am, i just try to relax you, though when i suffer nothing can console me but success...
If i was not enough clear this is going to enlighten you :

Length/gauge of wire? Whats the resistance measurement of the coil?

Sorry, I don't know. I get the wire from 3 Amp transformer primary (notice the black color lol). And my ohm meter busted that I can not measure in small range.

Got any tips on how to keep winding toroids from being such a painful job?

Keep the wire straight and wound it while doing something fun .

I had a rather frustrating session with Stingo too today. Found new transformers and coils that gave nice high frequency oscillations and sharp looking pulses, but put out no power.

My coil resistance should be around 2 ohm.

When you say no power do the oscillation die or just too small?

My best coil is still the starter coil and I've tried shorting things out the way suggested, it increased the frequency dramatically but no power output to write home about. So I went back to my load between HV and either terminal method. I was able to charge two AAA 1.2V nimh batteries which were depleted to around 0.6V each, back up to full charge in about 2 hours with the charging battery on the other side of a capacitor and FWBR. So that was nice.

That is the first time I heard such method work . Congratulation .

I will try to see reliability of my car coil for charging.

You still don't use the combined one yet . If you use three potentiometer, you have more reason to get busy too .

When two stingo combined, touching a point can make the circuit output double, touching other make it back half again. Changing one circuit potentiometer will change other circuit frequency, and the most fun part is when the output current drift from time to time that make measuring with single meter produce invalid result if you don't double check it ....

I now set the potentiometer to give max output when the battery is full. I let the circuit do whatever they want now .
