Stingo Solid State Battery Charger

[cikljamas]

Hi Sucahyo !
Thanks for your observation in "this is it thread" regarding bedini circuit...
I spent a lot of time today trying to figure out this circuit :

http://www.energeticforum.com/attachment.php?attachmentid=7484&stc=1&d=1269214875

Could you maybe help me with posting one of yours tested bedini solid
state radiant charger schematic ?
I tried one similar circuit few months ago and it did not work also...

I remember i saw in this forum somewhere how you talk nice words
about bedini solid state, but i have been unsuccessful when ever i tried
to replicate this kind of bedini circuits...

Well to help you i must tell that instead of h11d1 i use 4n25, instead
of 2n3440 i use bux 85, and instead of mj 15024 i use 2n3055, although
i do not think that this substitutes for original components are guilty
for my failure...

So, since you must have been successful replicating this circuit i would
be grateful if you post here one of your tested bedini solid state schematic...

Thanks in advance !

Cheers !

P.S. You mentioned that bedini solid state radiant energy pump is going
to appear as commercial version on the market...do you have any idea
about PWM that is crucial part of that amazing stuff as it seems it is ?

You know, it is very strange feeling when you are making bunch of circuits which are derivations of bedini solid states circuits and in the same time be aware of not being successful so far in tries of replicating original one...
So, who is going to help me about this if not you ?

I can only imgine what great successful it would be if we were able to
replicate bedini solid state radiant energy pump but without knowing
PWM...but first of course i have to successfully replicate simpler bedini
solid state one...

Purple flasher! and transistor killer.........

Here is a version of stingo that produce purple neon flashes. The important change is to put gemarnium diode between two coil in series, based on LaserSaber Joule Ringer idea. Both coil use same core. One on top of the other, but feel free to experiment with bifilar.

The circuit will lit the neon purple until the transistor break. The transistor I use is not important, I kill two transistor already lol.

YouTube - Stingo that produce neon purple



If you intend to replicate, prepare another hours winding the wire .........


Edit:
I found it impossible to measure the output voltage lol:
YouTube - Meter can be really unreliable measuring radiant circuit


Another report, I can run dead bulb sparkgap with car coil version of self desulfator stingo all night long (12 hours) with battery charge from 8.77V to 8.52V. Consume 80mA or so. Should be able to lit CFL at least dimly all night too.

I tried a few coils I had lying around.
The ones that performed the best where all air-core,
and especially my Brooks coil:

Thanks for the link .

Thanks for the info. I also had similar experience on transformer with iron core. I have more voltage and sometimes more current without the core. If it is possible, I would like to try air core toroid, but so far still fail to make stingo work with air core toroid. Maybe the requirement for inductance is a bit high for stingo.

@ sucahyo

I finally had some time & space to do a little testing
On top of my list I had the stingo circuit

Some kind of monster!

I haven't even tried to tweak it,
just picket a spot on each var-resistor and plugged it in;
man, this thing kills everything if your not prepared!

Lol, becarefull, I kill 5 fan....

How can I use stingo to discharge batteries? Is there a way?

Just use it as source, control the discharge current with potentiometer. With self desulfator version, you can control how much you want to discharge the battery. No Auto shut off though.

Sucahyo, do you think that this concept of selfcharging is promising ?

It seems separate battery for input and output is better. Maybe even following Bedini advise to use two battery in series for load and source.

Like I mention before, it can be harder.

If so, do you know with what i could replace this hal sensor ?
And do you know the values of these resistors ?
And is this circuit usable without microcontroller since i saw
a long discussion between Toranarod and Caru about source code
and it is in correlation with this circuit, so i am not sure if it is
worth much effort if microcontroller is unevitable part for good
functioning of this circuit ?

Sorry, I don't knwo what circuit you refer too. But my principle is sharp pulse. With pulse at certain frequency.

I tried today bingo negative - positive mode charging small batteries and bingo destroyed a few batteries, it seems that there is much more voltage on the bingos output than on the stingos output...
Before i thought i can not use bingo in negative - positive mode,
but after i discovered i can use it i decided to make test, and i just
told you how it ended up, so do not try charging small batteries with
bingo...

Thanks for the info. That is why I prefer partial cap isolated FWBR to charge a battery, even if it has worse efficiency than single diode. Battery can become capacitor if charged with only radiant.

How do it destroyed? Overcharge or over discharge can destroy battery too.

Happy new year everyone .

I hooked two half dead 12v batteries in series to acquire more voltage to charge another battery. It seems that even the source batteries are going higher in voltage. Does Stingo self charges too?

I agree with 7imix, it could be self desulfating, not self charging. I think cikljamas experience this too.

See if it still produce that effect after few cycle.

I never observe that effect though. So, congratulation .

Sucahyo, i found the very simple way of connecting two charging devices (i used farmhands desulfator since it seems its efficiency is the best) using negative-negative mode and few days ago i tested intercharging of two batteries so that relay was switching between these source/charging batteries every 2,5 minutes, and after awhile (few hours or so) i noticed that there is slightly discharging from both batteries instead of charging as we supposed it could/should happens according that formula, and with help of possible advantage that this on/off method could obtain...

So, i was disappointed, but what can i do ?
That formula promised a lot, but it seems it does not work like that in
practice...

Thanks for the test .

Realize that what is proven to be best at one test do not mean it would produce best at other test.

Farmhand desulfator with negative to negative may produce good COP on meter test, but it may produce different result on battery swapping test.

We should not rely only on COP meter test.

I would try everything I know with battery swapping test. Don't assume that the best in COP meter test is the best in battery swapping test. That is wrong. Try everything.


I still working on my timer. But will be ready to test it this months.

Here is what I like to use for test:



I will try circuit of:
your bingo, stingo (bottom diagram), stingo2p (top diagram). I don't try timer based because I had bad result before. If farmhand desulfator is much superior, I would try to use the same MOSFET into stingo or bingo.

The output capturing method:
- single diode negative to positive
- single diode negative to negative
- partial cap isolated FWBR
- optional diode from source negative to load positive
- and the charging-self charging methode showed by Toranarod:

http://www.energeticforum.com/renewable-energy/6959-robert-adams-pulse-motor-design-review-5.html#post123946

That is a lot to test. But the result would test me which method is best for battery charging and will see if COP meter is consistent with battery swapping COP.

relay switching - charging

devices(i used farmhands desulfator since it seems its efficiency

In the past, I have suspected this might be a possibility, if it is tuned properly. I even saw the current simulation run backwards in a version of stingo that I built in a circuit simulator app. I have to play around to find the right inductance, resistance, and voltage again though.

It could also just be desulfating the source batteries as it charges another battery, though.

Stingo test

[sucahyo]

Thanks. What is shown is not the increase of charge of battery though. It is just an increase of voltage. With broken battery I observe the voltage go up and down during run. On capacitor it will always deplete.

I found it to be a great circuit for discharging a battery.

When we condition the battery we charge and discharge. I have charger that can vary current, now I have discharger that can vary current too. Both doing great to desulfate battery .

Self charging

Self charging is amazing this is great achievement Sucahyo
Thanks

[sucahyo]

Finally, isolated coil version

I finally succeed in isolating the coil with another PNP, Inspired by Bedini patent. My first implementation is self charging, inspired by Mile_high post about callahan:



The result is not COP>1, the battery kept discharging. But it is still interesting that the circuit do let the battery charge it self.

Battery voltage 2.74V standing, 2.51V running without load, 2.63V self charging. Consume 280mA running without load, 130mA self charging.

In normal use:
Efficiency two nimh charging two nicad, with normal FWBR charging 80ma consume 200mA = 40%, with single diode charging 90mA consume 190mA = 47%.

Worst efficiency surprise me.


Video of stingo application for self desultfator:
YouTube - Stingo self desulfator

Standing voltage is 4.25V. After attaching the circuit voltage go down to 2.91V that slowly rising to 2.95V.
