Joule Ringer!

[Allen Burgess]

Battery resonance.

@minoly,

You're probably right, I may have just found a new way to wear my battery out. The industrial tolerances of factory transformer windings and battery and bulb manufacturing bring precision to the circuit. The battery voltage depleted untill the voltage hit exactly 12 on the button, then it just sat there! May just have humed up and stewed it's own juice. The power set to the factory bulb setting, the second bulb rings in resonance too. An inductor between the R C tank and the transistor base increases voltage enough to illuminate 4 Watt flouresents. The problem is, magic of resonance should disappear with those voltage mis-matches.

@T-1000,

I'll get to work on that scope shot.

Hi,

Can you please attach 1 Ohm resitor in series on battery and put oscilloscope over it? It will show what is going on and Ohms law can be applied there.

wouldn't that resistor also kill any ringing that could be going on in the battery?
couldn't hurt to try, just a thought though... perhaps Alan has found the natural resonant frequency of his battery and electrolyte.

Flip flop

I replicated the flip flop last night and tried to use the same values called for in the french circuit. I only had some small signal MOSFETs on hand so that's what I used. They got hot very quickly so I swapped them for a couple of 2N3055 transistors so I could heat sink them and they seem to work just as well. Putting out some nice light with this thing. Running it off of a 14.4v Roomba battery.

@ jonnydavro

I tried your inductor mod - great idea. In the following circuit the tube will not light without the base inductor but does light with it. A definite increase in the output voltage.



EDIT: The inductance value is wrong in the drawing notes, it should be 14 mH not 14 uH.

More success

@ Jonny
That new circuit look very interesting. It is something new to try. It always amazes me how one idea leads into another on these threads. It is a builders paradise as there isn't much idle talk----just a bunch of people working hard making things.

@Skywatcher
I looks like you are having similar success with the "French Flip Flop Inverter". I worked with it again today. When I box it up I think that I will leave it with just a wall outlet plug so that I can use it for what ever I want. I found out that I can plug my notebook computer 110v charger into it and it will work.

@Xee2
I went to my local Radio Shack and bought the exact 12v transformer that you are using and it worked the same as the one that I had on hand. I might make a second boxed unit using your circuit and this RS transformer.

@All
I was able to use a plain old Joule Thief circuit to trigger a four wire tranformer----but I did it in a weird way. I set up the JT like a traditional one with a small toroid transformer and ran it on a AA battery. At the LED off the collector, instead of connecting it to the neg rail like usual, I connected it to the base of a 2n3055 NPN. The 2n3055 emmiter was connected to the (-) of a 12v battery which was also connected to the (-) of the AA. A four wire 12/120v transformer was connected between the (+) on the 12v battery and the collector of the 2n3055. A 5K pot on the transistor base of the JT circuit controlled the whole thing. This actually worked very well. I tried to set it up with just the 12volt battery doing it all but couldn't get it to work.

french inverter flip flop circuit

Hi folks, Hi jonnyd. thanks for sharing the info and video.
I hooked an even larger 5 disc changer boom box to the french inverter and on high volume, it draws around 300 milliamps or 3.7 watts.
On the back, it says 120vac 25 watts.
Nice to know your circuit and this one can power lights and radios, etc. for whenever needed.
Both the xee2-saber circuit and the flipflop french inverter circuit are way more efficient than the vector inverter i have, the vector needs 5watts just to sit there no-load and even the small cigarette lighter ones need between 4-5 watts no-load, so the benefit is obvious with led lighting and lower power devices.

edit: allen, yes thanks for sharing the info and videos, you may have hit a sweet spot and i thought about the circuitry in the led bulb causing some beneficial feedback as well, so you might be on the right track.

Voltage.

@Xee2

It's a 12 volt 6 amp hour. If I double the amp draw and bulb brightness, the voltage begins to drop noticably, but it seems to not be effected at all by the bulbs at the lower range. I ordered 10 more 120 volt bulbs to test the upward limit with. My instinct tells me that there's more to it then just super efficiency. I believe power manages to loop back to source through some special characteristic of the bulbs. Your formula tells me it should have droped 2/5 ths of a volt, or for the time it ran, but it stayed the same. I'll run some more tests. Thanks for the feedback.

with no visable change in source battery voltage

Battery voltage is not a good indicator of energy in battery. What is the mA-hr rating of your battery? If you look at the mA-hr of use (that is, hours times mA being used) divided by the mA-hr rating of the battery and multiply by 100 to convert to percent, you will get an indication of what the percentage of battery energy you are using is. If it is only a few percent, I would not expect the battery voltage to change much. I suspect that large battery will supply 180 ma for many hours before you see any voltage change.

Xee joulthief inverter with relay coil

Hi.I had a go at Xee's Joulethief/inverter today and I did not have the right transformer but I did have a twin 120v input,twin 12v output one which is quite easy to convert into a joulethief by just connecting the two inner pins on primary and secondary so i tried that and it worked but the output was not too high,probably due to the turn ratio of my transformer so I tried a trick which introvertebrate and myself have tried on Bedini motors which is the addition of a small relay coil to the base circuit and that changed everything.The first thing that happened was the output increased significantly.The additional bonus is that 2 more sources of HV appear across collector emitter and also the relay coil.Both of which could be used for lighting or charging.
The circuit will light cfl bulbs quite nicely and i hope to get hold of some LED bulbs which I think are the best form of lighting for this circuit,judgeing from results posted here.
I also tried running a mains powered radio which is 240v in the UK and it worked quite nicely so I will try and find a 5 pin transformer next and see if output increases.
Here is a circuit diagram and vid.Thanks Xee .Jonny.

Unity Light.

This video consists of my running two 120 volt LEDS around 180 milliamps in draw with no visable change in source battery voltage drop. It ran for half an hour before I started the video and an additional fifteen. Proof it's running at unity in resonance. One can fast foward through this one.

endurance - YouTube

The results of both experiments indicate that this circuit may be looping power back to source. Hence, the zero increase in amp draw with an additional bulb, and the absence of voltage drop when running at peak resonance.

[SkyWatcher]

Hi folks, well I tweaked my french inverter circuit, ideal resistor value for mine is 1150 ohm instead of 4.7kohm.
With my transformer winds, it can't output much current for anything other than led strings, though it could light dimly a 25 watt incandescent.
I will make another transformer for higher power, this one will be strictly for led lighting.
It seems to run the led strings very efficiently.
In the picture are 94 leds at full brightness at 12 volt- 260 milliamps or 3.2 watts.
Now the purple led string has 60 leds and is supposed to draw around 4.8 watts and the multicolored 2.4 watts or so.
So indeed, this circuit is performing well. Here are a couple pics.

More good news

@All
I found out that the "Flip Flop" circuit will work on a transformer that just has the four wires (no center tap). All you have to do is just use one half of the circuit with one mosfet and leave the other half alone. This is good news to the guys who are having trouble finding the center tap transformer. The amp draw seemed higher but it is a way around the problem. You can find the center tap transformers pretty easy though if you look around. It is a common item.

Lidmotor

PS----I too am wondering about the efficiency numbers of these things. It is pretty good bang for the buck.
