Stingo Solid State Battery Charger

[sucahyo]

Hi sucahyo you're the inventor of stingo circuit?
Thanks

Yes, I found it by accident.

Some people mention that similar circuit already around. However, I don't think it would produce same result as stingo. Stingo principle is by triggering PNP with coil spike to make it drive the NPN better. Still wondering if we can drive NPN directly with the coil spike.

The use of diode and transistor should be meaningless from conventional point of view so I don't think everyone ever made stingo before.

Hi folks, Hi cikljamas, thanks for reposting that information and picture about your results.

how close
Hi guys, i am jealous of your forward steps (a little bit), and i have to
ask you 7imix, what are the chances for you and me to make any
progress with this project using your ghetto toroid ?
I`ve been messing around yesterday with this :

And these leds are lightened guess with how much uAmps, not mAmps ?
With 10 uAmps !
In two hours these two AA batteries depleted for guess how much mV ?
For four mVolts !
So, how close to OU is this ?
Cheers !

Could you possibly post a circuit, so I can try and replicate it, thanks. It looks like a standard powdered iron toroid? I have a few of those and smaller ferrite ones.

Best regards Sucahyo very good circuit I hooked it to a small solarpanel and still works about 20ma. Amazing circuit nice nice
Thanks

Hi folks, Hi cikljamas, so I'm going to assume based on the recent photo you posted that it is a joule thief connected to the battery saving device which contains the 5 leds. Sorry if this is off topic, i don't know where else to respond to cikljamas to get more info on his circuit. Though i also plan on making a stingo.
Here's the pic of cikljamas battery saving circuit, which i assume connects to the output of a joule thief, though i see 6 wires on his toroid so maybe hes using the third wire as a secondary takeoff going to his battery saving device. Any added information to clear this up is greatly appreciated, thanks.

Hi folks, Hi sucahyo, Well i finally got around to putting together a stingo circuit.
It certainly seems efficient.
I'm also seeing the ability for it to charge larger voltage batteries from lower voltage source and it's a good charging rate, unlike other oscillator bifilars i've tried.
I'm using 3 AA nimh in series charging a 6 volt 4.5AH SLA off the flyback and also charging a 12 volt 7AH SLA off the secondary off the transformer I'm using with FWB.
I'm using a TIP42 PNP and a NTE2300 NPN.
We'll see how well this puts a charge on batteries.
It's nice to be able to pulse coils without them having to be bifilar and such.

Hi folks, one more thing.
Can anyone explain how this reverse mode pnp circuit is able to oscillate.
Is the positive polarity of the input battery able to flow through the pnp collector and the negative through the base and is that allowing the pnp to turn on just enough to kick on the npn? Thanks.

Stingo

Hi sucahyo I did a vid on your circuit is it ok?

YouTube - Stingo Circuit

This circuit can be used for relaxation you said once as I remember? What I should add to it?
Thanks

Hi Skywatcher, is there any nlo out there ?...Sorry i didnt see your post
in the right time, but it seems you figured out just by yourself everything
correctly ...

Yes, joule thief is connected to the battery saving device, by now i suppose
you already replicated your own battery saving device which is very nice
thing...

It is embarrassing but i have to admit that my calculations was wrong, and
draining just microamps was just my dream, no, my joule thief drains
between 20 and 30 mAmps, and battery saving device drains about 10
mAmps (measuring after joule thief which is output side of course), and if
you want you can use this batt.saving device without joule thief using
12 V battery, it means you just hook it up directly to 12 V battery and
for the cost of 9 mAmps you have super bright leds to lit your room or
what ever you need to light...

So, there is no microAmps wonders but even without that dream of mine
this combination (Joule thief + batt.saving device) is great little toy that
can give you a lot of light for very low price...

Enjoy it !

Peace and love !

Nice to see you cikljamas .

Hi sucahyo I did a vid on your circuit is it ok?

YouTube - Stingo Circuit

You charge with +1V increase with only 20mA of input? that is nice .

This circuit can be used for relaxation you said once as I remember? What I should add to it?

It is just a play of polarity. We use the negative and dump the positive. We connect the negative output to our body or our bed or an antenna, after we connect the positive output to water in a bucket.

Do not connect the positive output to ground!

I use this circuit bellow. If you use 12V source make sure to add 1K ohm to the PNP base to prevent you from accidentally frying the PNP. The circuit bellow can not be used to charge because of missing 500K pot. With 3V source, output can reach 150V if connected to metal mass and a bucket of water. Around 30V without.


Now I choose to use battery as power source and I wrap the toroid with alumunium wrap.

Stingo

Hi Sucahyo thanks for response. Regarding your last schematic what's toriod ex PSU? Same toroid as other stingos?
Diodes 2amp as usual?Resistor 1/4w?
Thanks

[cikljamas]

Nice to see you too Sucahyo !

Let me present you my modification of one charger circuit
that i saw somewhere on internet :

http://img33.imageshack.us/img33/959...ttcharger2.jpg

I use it for charging small batteries and i am very content with it...

You remember bingo problems charging small batteries ? After that
i started to think of stingo in similar way, too high voltage for small
batteries radiant chargers like stingo produce on the output, so i think
it is not good solution too (stingo) for charging small batteries...

Dont you think so ?

Btw, any suggestions which thread to watch ?

I mean, i would like to engage in some productive project, but i just do not
see something that suits to me , and i always look for something simple
and effective like joule thief, stingo, bedini window motor, etc...

I bought one sony super quick charger for small batteries, and i disassemble
it (i had to use something else instead of screwdriver, hahahahha), i was
hoping that i maybe could have been able to replicate it, but when i opened
it, surprise : what did you expect sucker, maybe some schematic and ticket
for hockey game ?, hahaha...in there smd components, unknown parts, just
unusable for my intentions....

Then i wanted to buy max 712 or max 713, but it is too expensive chip here,
so i am not sure if it was reasonable decision to buy it just for experiment
purposes...

Yes, similar to other. But don't hesitate to use better one. Since we don't use the current, only the voltage, I think diode with less amp rating can be used too. I only use 2Amp diode for output only. I think fast glass diode is better for the PNP to NPN diode but may need scope shot comparison.

Interesting. But that 5 watt resistor made me wonder with the heat. Also what kind of electricity being transfered to the battery.

How long that circuit need to charge two nimh/nicd in series? What is the end temperature, is it hotter or colder than your arm pit / body?

Mine, two 2500mAh nimh require two hours with 1Amp input at 11.5V, with battery temperature never hotter than my body. two 1000mAh nicad require 1 hour.

I don't agree. The circuit will self adjust. If we just need lower voltage we only need to adjust it so it will produce lower pwoer. I have been using it to charge small and big battery many months now.

Btw, any suggestions which thread to watch ?

How about earth battery thread where Mr Bedini share simple way to make battery that last forever.

True. But I think you should compare its performance first.

Stingo to HHO

Hi Sucahyo I think once I saw a schematic with stingo circuit for electrolysis.
If I am right can you please send me a schematic?
I have a problem on one of the circuits that I've built; the Tip31c is getting very hot.
Any clue?
Thanks

[sucahyo]

I use any stingo I had for electrolysis. electrolysis cell replace charged battery. I think the one diode recovery version will work better. Try your current one.

I have a problem on one of the circuits that I've built; the Tip31c is getting very hot.
Any clue?

Unfortunately, that is normal in stingo circuit. You have to add heatsink and maybe add fan too.

What is the current consumption? 1 Amp would be too high. I usually limit to 500mA input on each stingo.

To get high output current, I use more stingo each with low current, instead of running one with high input current. But in case you have good cooling system, I think using one is ok. But watch the coil temperature too.
