Stingo Solid State Battery Charger

[sucahyo]

Thanks !
I suppose you mean yes for this other solution, L1,L2, and L3 ?
Or you mean yes for both (including secondary over standard stingo)?
I have to try this, but since cfls are not so cheep here i have to wait
that one of my cfls that i am using for lightening my apartment fail,
and then disassemble it...

Yes for both solution. You need secondary that has more wound than the primary.

The quality of CFL here is so bad that I have more broken one ....

Yes, something like that .

You mean, you wind secondary over first stingo toroid layer or you use special toroid instead of stingo standard toroid, for example like i saw in JT thread 4 turns for L1, 4 turns for L2, and then 80 - 400 turns for L3 and all that on standar one inch toroid ?

Yes, something like that .

Yes, we can use secondary HV to lit CFL. Best result obtained with correct primary secondary ratio, but I am not sure what ratio. I get brighter CFL with 9V/240V transformer than car coil. I once get full brightness with 3 watt.

Go and see my new thread super charger "bingo" , i name it by
stingo changing just first letter...I would like to see your opinion on that !

Cheers !

Hi Sucahyo regarding capacitors we're always talking 1uf 250v?

I use that capacitor, but I think you can use any value. See if bigger or lower capacitance change efficiency. That require two amp meter at input and at output.

When testing if it's working what do you do a neon?or a meter? and where to the output?

We can replace charged battery with neon or meter. Or put amp meter in series with charged battery. You can also hear the coil sing sometimes.

Sucahyo, could we light the cfls with stingo somehow ?

Stingo

If you have two amp meter, see if this circuit bellow produce better result:


My feeling tell me this one better. But I only be sure after testing with two amp meter.

Inspired by Farmhand pulse charging, I try to charge 12V battery with 3V sparker:




The neon end up lit all the time. It is harder to make the neon pulsing, but can be done....

YouTube - HV pulse charging


May not be efficient, but still fun .

Here is video showing the effect of HV secondary to neon bulb brightness and charging.
YouTube - Stingo car coil HV connection choice

If you use car coil, short the secondary or connect to the load positive.

Hi Sucahyo I did this one posted is it for charging or there's another?

FWBR version?

Hi Sucahyo I did this one posted is it for charging or there's another?

[sucahyo]

Stingo window cole test result = fail. I can only run it with single diode which defeat the purposes of having enclosed coil.


BTW, can anyone having scope check if using two PNP in tandem/paralel/leg by leg will produce double spike?

[sucahyo]

Wow, great expectations ! Should i try this today too, or better to wait your impressions first ?

Prepare for non working circuit if you try, I still not sure about the connection.

And i thought 300 mAmps is to much , but maybe it is optimum for two hours charging, but if your output to the battery is 500 or 750 mA, than you have to stop charging after half an hour, because this is quite enough time for batteries to become hot with so much mAmps, am i right ?

Only on zinc carbon. When I forget to stop charging after it already full, the nimh and nicad do not get that hot. Still colder than cheap commercial charger.

I charge 2500mAh nimh in two hour. But that kind of amperage is not high, compare it with this:

charging 1700mAh under an hour require 2600mAh ...

Actually I am thinking of doing similar configuration, with stingo:


I will try this today.

I don't put attention to the current I put to the battery. I just let it stay in my double stingo charger until it get hot. If it is nimh or nicad or SLA until it get warm. Current should be between 500ma to 750A.

Oh, well, now it make sense, but still puzzled how come you consider reducing the consumption of current in reverse mode as rising of the efficiency too ? My measurements do not prove that, efficiency stay the same, we just have to adjust pot. to higher resistance to reduce consumption of current in normal mode, but it doesnt mean that efficiency changes at all, at least according my notations...Maybe i miss the point somehow or i just have to make more experiments...

You mean you reach similar efficiency at high frequency? Well, I only have one digital amp meter, so I conclude normal as less efficient when I see result.

Another reason is PNP will flow current is dead. When the circuit is not oscillating, the PNP will kept drawing current from the source without powering the load. I think duty cycle of the NPN would be different. maybe 50% at normal mode and 1% in reverse mode. Godfrey and 7imix can confirm this?

Another reason is I use low frequency in real application.

Does this mean that if i change this bedini window cole circuit in the same way as you did with stingo (reverse PNP) i am going to reduce current consumption just like it is case with stingo ?

No. different functionality, reversing will make it no longer work. Stingo is use PNP as trigger. The windows cole circuit?, use PNP as switch.

I will try this today.

How many times you estimate we could recharge these non rechargeabled ( )batteries ?
And what current input you use for 1,5 V batteries
and what current input you use for 9 V batteries ???

Thanks . recharged non rechargeable battery pnly usefull for something that do not draw much current like remote or calculator. But bigger one like AA or D-cell can lit torch light decently.

I don't put attention to the current I put to the battery. I just let it stay in my double stingo charger until it get hot. If it is nimh or nicad or SLA until it get warm. Current should be between 500ma to 750A.

Today I finished my stingo circuit and tried it on two dead batteries. With amazement it charging the other with only 4ma
I am posting my circuit photo thanks to sucahyo help.

Nice achievement .

I can't see it well, is that FWBR version? if you intent to use it for battery charging or reviving, use the FWBR version.
