Circuit diagram

Hi Sucahyo thanks for help. About the diodes what kind of diodes should be used 1n4007? and regarding toroid about 2ohms right? and how much wattage those resistors?
Thanks

[7imix]

Thank you. I wonder what is required to make continuous secondary oscillating one.

When you reach 30Khz, did you change other potentiometer value? I recall I have to change the other if I want to use high frequency version. I think you can get even higher without neon bulb as load.

I think I need to build a stingo with even more potentiometers to get even better fine tuning. For the 500k pot, a 500k, 50k, and 10k in series; for the 10k pot, a 50k, 10k, and 1k in series; for the 100k voltage divider resistor, a 100k, 50k, and 10k in series. I find, especially with the 500k, that interesting waveforms occur in a very small range of tuning, it would be nice to tune the rough pot until I get an interesting waveform and then tune the finer pots.

Yes, in that video, I was changing all pot values to attempt to get the highest frequency. I got a "feel" for it while tuning them but it's hard to describe and impossible to show in a video.

I have been dreaming about a stingo with digitally controlled pots, with a readout somewhere that shows you what each pot is set to... Someday...

[sucahyo]

Thanks for the winding info everyone .

I got a very interesting waveform where the impulse wave was causing an oscillating wave, but only at a very specific tuning.

I was able to get the toroid to oscillate at 30khz, which I think is a record for me with the stingo.

Batteries are not as straight forward in how they take energy. But how 'bout measuring input current and timing how long it takes to charge a capacitor with well known capacity to a certain voltage? Then just do the math to figure out total wattage?

That is nice idea . But we may need a big capacitor to do that. It filed up 10000uF in just seconds...

Hi Sucahyo so for charging like this schematic to be sure?.

No, for charger use the circuit I post. Your diagram is lesser alternative. The diagram need to be corrected, the connection from charged battery positive to source negative made it wrong.

Hi 7imix, I'm using a bridge rectifier to charge a battery and place the probe and ground on the AC connections of the bridge, so i'm charging a battery while I do it. yes I did see your frequency go up to 28khz but it looked like the waveform got a little less straight to me after a point in the video, not much though.

Here's a shot

I see, the stingo produce different h wave depend on load. Thanks .

Sucahyo I remember you talking about a small capacitor in series with the the bridge on stingo could you tell me how that is wired is it placed accross the AC connections of the bridge?

That already included in my latest diagram:

Nice, thanks farmhand.

Though I'm not exactly sure what frequency that is. I think onlyabout 12khz.

Edit#2 7imix, I forgot to answer your question about the coil, sorry. I have a couple that do it one is carefully wound 3 layers on a 10mm straight cylindrical core about 28 winds total 1mm wire, the other is less than 15 feet 0.7mm wire very roughly wound on a toroid. 20khz seems to be my Stingo's limit.

[7imix]

7imix, that waveform does look interesting, I can get 20khz reliably with mine and its still on the solderless board But my waveform is AC where do you place your scope probe and ground? And do you have a load connected, for recovery I mean ? Thats impressive, a quite straight up and down trace there at 14 khz I think it was. I will watch it again more closely.

Cheers

Looks like up to 18 khz quite straight.

I am not driving a load, although I do have a neon bulb across it and the spikes appear to be high enough voltage, I do not observe the neon lighting.

I actually observe it going up to 28khz in the video. I was also able to observe 30khz but could not get it on video. What are the details of your coil's construction?

I measure the output across the two sides of the coil, with the probe leads reversed from the current direction of the rest of the circuit. Where do you measure and see a sin wave? That's interesting.

Can you define basic? If it is for charging then use this circuit bellow without the part at the left of the coil, and replace it with one diode:


For sparking experiment, remove the 500K and 100K part.

Measuring output

Wow, happy that this thread is so lively and hoping to have more time to catch up. Great work all!

Bedini show charging happen by the increase of voltage of the battery. But I agree that what we measure is just the conventional power.

Batteries are not as straight forward in how they take energy. But how 'bout measuring input current and timing how long it takes to charge a capacitor with well known capacity to a certain voltage? Then just do the math to figure out total wattage?

30khz stingo

I wound a new toroid today. It's about 15 feet of 22 awg wire around a ferrite toroid about 0.6 inches in diameter.

I got a very interesting waveform where the impulse wave was causing an oscillating wave, but only at a very specific tuning.

I was able to get the toroid to oscillate at 30khz, which I think is a record for me with the stingo.

[sucahyo]

but it is enigma to me how to measure output volts
when you connect battery on the output...

I think it is more unfair to measure voltage without load. That is my best choice.

Did not we already talk about radiant energy as something that is very hard to measure with certainty ?

Bedini show charging happen by the increase of voltage of the battery. But I agree that what we measure is just the conventional power.

Output voltage should not be dependent of voltage of charging battery,

Yes it is. When the battery gets full the impedance change. Stingo input power, output power and output voltage will change depend on load impedance.

Notice that the output current will increase when the battery gets full.

Maybe wattmeter would burst this bubble of dilemma right away,

You need a load too in watt meter....

Yes, I am aware of problem measuring the COP this way. But I think we can figure out at least how much the current that goes to the battery. Where the charging voltage must be higher than the battery voltage or else it can not charge the battery.



How about this:
use amp meter as load and then measure the voltage at the amp meter. Would this be more accurate method of measuring output power?

Hi Sucahyo, That is when the oscillator is not running, eg. in continuous conduction. I dont run my oscillator staight from the panels in my setup, it is powered by my backup battery bank. I would need a few Stingo's to put 3.2 amps through maybe four.

With my solar setup when the oscillator is running the output is high frequency pulse on low frequency pulse, in a way, about 7.40m on the Circuit Video it shows me trying to adjust my old scope to show the ouput properly, but it can be seen. It seems to be good for reviving big batteries that are hard to get charge into. I think I just got another one online, so thats 3x640 cca batteries revived now, one to go.

I would like to try Stingo powered directly from a 5 watt panel, as the panel battery interface, not sure what would happen I imagine when the solar panel output goes above the max amp draw of the Stingo the voltage would then rise which would increase the amplitude of the spike, I think. Can't wait to try it.

But alas i'm still layed up probably a couple more days. My billy goat done a good job on me again ( I call him George B.) he's very destructive.

Thanks.

I don't know about recovery, but I have observe longer life and cool charging with stingo.

I will look forward for your result. To tell the truth, I somehow believe that stingo as sleeping aid can calm the goat. Would love to see its effect to the goat too .... I currently in hot debate in a group about a health device because I doubt if it can calm people or really have good effect on long term.

I appologise for getting off topic, but we should be carefull if we put too much load on the back end of stingo this might happen to him.See attachment

Lol, that is accurate though . Overloaded stingo will lift the load from the source .....

[Farmhand]

Sorry couldn't resist.

[Farmhand]

But, how come that we decrease voltage on the output just by replacing
charging 12 V battery with 3 or 5 V battery ?

cikljamas, It is a common oversight it tricks me sometime's, to get a good idea just measure the input and output current the way you are then when your ready to make the calculations just measure the input and output voltages at that time, no need to measure them constantly.

Cheers

In my opinion it would be easier to measure OU possibility with a cap discharge on the output between the Stingo and battery. A battery will pull the output voltage down to the battery voltage.

[Farmhand]

I can with my solar setup get more Amperes from caps to battery than from the panels to the caps without pulsing(eg steady flow state) but this is because the caps are a couple of volts above the battery.

My panels are rated at about 3.2 amperes at 17v I think (not sure exactly),
but if I connect them to a battery that is only 10v I get almost 4 amperes of current flow. Not exact but close to what I seen happen. No cigar for me though.

To make everyone more convice, you need to show input voltage, input current, output voltage and output current. Then show the calculation of input power compared to output power. Your overunity video do not show that.

While getting more output current is rare, some people would ignore if it do not show voltage in and out.


So, make another video that show your output power is greater than input power. Maybe they will comment it for sure .

Well, it seems i should have wattmeter, i must buy it one-one of these days...
But, i think it should be possible to measure V in and out, and A in and out
with 4 analog meters, but it is enigma to me how to measure output volts
when you connect battery on the output...

Did not we already talk about radiant energy as something that is very
hard to measure with certainty ? And if you have 12 V on the input
should we have doubts that stingo gives on the output less then 12 V
even with pots set to highest value (100 k for example) ?

For instance i just disconnected these 2 AA charging batt., and set pot.
of one of my three stingos to highest value to decrease imput current
as much as it is possible, and put meter on the output : 32 V...

But i guess it is not the right way of measuring again...
So, when i charge 12 V battery with 12 V battery and i got 60 % efficiency
( 350 mA input 200 mA output ) than it is 60 % for real because 12 V are
from the both sides, but if i just replace 12 V battery on the output with
3 V or 5 V battery and i got 240 mA on the input and 300 mA on the
output it does not represent OU ???
But, how come that we decrease voltage on the output just by replacing
charging 12 V battery with 3 or 5 V battery ?
Output voltage should not be dependent of voltage of charging battery,
if i do not touch the stingos, just replace the charging batteries, how
could i change the output voltage just by replacing charging batteries ?
It does not make sense to me, but it is possible that i just do not know
how this things work !
Maybe wattmeter would burst this bubble of dilemma right away, but
i am not sure if wattmeter could give exact values of output voltage too ?
So someone has to enlighten me again since my ignorance is so great !

Farmhand, thanks to you also for your help !!!

After all, it was not OU ??? Why dont you let me to believe it is ??? Joke !
But, i am going to hope just for a while that it is, until you explain me why
it could not be so !
