Stingo Solid State Battery Charger

[7imix]

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

Yes, sometimes I have observed the motor running but the stingo is not oscillating, and there is just flat DC (not pulsed) at the radiant output. Yes, I think the NPN just stays on, and gets very hot. I will try to investigate more and report. I think I have seen this the most when trying to run brushed DC motors.

Stingo versus JT

Sucahyo is there a differnece in output from stingo circuit to Joule thief?
My JT is lighting the neon too in DC mode for sure and consumes around 200ma. Neon is lighting very bright.I'm using a 3055 transistor.
Thanks

My first experience winding one involved lots of cursing. At least I'll turn on the TV so no one hears that

This is not something that we should make joke about, but if you could
see how i looked like, and how i cursed while i was wounding that toroid
i think that would have been great consolation for you...But, as i said :
It is not fun at all, especially concerning differences between american and
croatian way of cursing...When i curse i really very sorry that i am croatian...
REALLY !!! It is not joke at all !!!...But, when i have read that your curse
too, beside other similarity that i already wrote about, i just could not
resist my temptation to answer you again...

I've got more posts I want to respond to, just out of time for the moment...Cheers

Might be you have some bad feelings about me...But if it is so, then you
just do not understand croatian humor...There is no such thing
indeed (croatian humor), but croatian way of cursing unfortunately exist...
Now i remember how Edison answered to Teslas demand to pay him what
he promised after Tesla repaired some complicated machine ...Edison answer
was : Tesla, you just dont understand american humor...But that was
important turning point in Tesla life, and after more then 100 years, our lives
too...If this dialog (between you and me) become a cause some new
electrical revolution then it worth me to endure your revenge...But i am
affraid a little bit of not be able to understand american humor...Never mind,
humor is humor and it is welcome in every moment and in greatest amount,
especially after whole day cursing...

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.

Visually, I guessing around 16 gauge. You could measure it with a wire stripper.

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

My first experience winding one involved lots of cursing. At least I'll turn on the TV so no one hears that

My coil resistance should be around 2 ohm.

Thanks - that helps.

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

It's a power transformer with a thick HV output wire coming out of it along with many other terminals. I got it out of a computer power supply.The oscillations do not die and look fantastic in every way, it's just that I can't see any more power coming out of the standard output points you designate in your circuit, nor any other combination of transformer terminals, other than the 30 or so volts I see in the signal coming off the PNP base. It looked really promising. I even got the HV shorted to what I believe was the secondary, and the oscillations still ran, but at twice the frequency. I think I got it oscillating around 28kHz.

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

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

I have two of these starter coils. Maybe I'll try to pair up their output.

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 ....

This confirms the drifting I was experiencing even with the starter coil yesterday. I had the thing putting out enough to register 200V DC on my multimeter for awhile. Then it disappeared and the best I could do after that with all my 'knob twiddling' (the scientific art for any Stingo technician to learn), was 60V and that's what I ended up charging with.

I've got more posts I want to respond to, just out of time for the moment...Cheers

Here is stingo with car coil result:
3V charge 12V at 60mA


12V charge 3V at 1350mA


resistor at PNP base at 100 ohm, at 12V the PNP get hot quickly. Neon bulb only connected to the HV part, one wire mode. Secondary not shorted but also not utilized other that neon.

[sucahyo]

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.

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

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 .

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 :

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.

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 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.

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 .

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

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 !!!

Maybe because the charged battery state is different. The first one have sweet spot, the second has output proportional to consumption.

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.

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.

[cikljamas]

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...
