Big Joule Theif

[Vaporizer]

There is really no reason it shouldn't work.
You are dead on abt the oil. It was used as a cooling agent and it has another unique characteristic. It is a "self healing" coil. With oil as a medium, if it should arc, there is no carbon trace left for it to continue to follow. Solid materials fail in this area as an arc will leave a weak area of carbon particles and it will continue to fail and follow the same path creating an easy carbon traced shorting path. Automotive coils were extremely reliable and long lasting for those very reasons.

Hope that answers some of you questions....

Hi folks, figured this was the best thread to put this in. I took apart an ignition coil for an automobile, like the one imhotep used in his relay fluoro light. The reason I was forced to take the coils out of the casing is because the case was made of metal and so just placing a feedback coil on the outside would not work for making a joule thief type oscillator. What I have found is that it is filled with oil as most know, though i'm not sure if it's just for cooling or for electrical insulation for arcing as well. Also, the inner secondary coil had a gap of about a 1/4" from the primary coil. The primary looks to be around 24 gauge at 1.8 ohms and the secondary is 11 Kohms. I will not be using the primary coil. I plan on wrapping the secondary with 18 gauge wire in bifilar configuration to make a joule thief oscillator and see how well the secondary outputs into a cfl.
Also, the high voltage positive output that came out of the top of the ignition coil is actually wired to the core, which i did not know they did it that way and that spring in the pic was used to link the core to the top electrical output wire.
I have no idea how it will work out, though i'm hoping it outputs well using 1 AA rechargeable or at most 2 AA cells. Here is a pic for anyone interested.
Let me know what you think of this.

Guys:
Since the Captret - Jt set up that I'm working on uses several caps (9), and the negative posts of some of the caps were not being used. I thought of feeding-back the unused caps negatives posts voltage back to the joule thief, or the battery. And it works better, so far, the single led lights up a bit stronger, as it was getting very dim at times. Yawn...
I don't know how it will affect the two or three 9 v batteries run times, yet, or rather their self recharge rate. But, there's a possible untapped potential there in the circuit caps negative posts, that do have some juice to offer also, (at least in my circuit), and that can be recycled back to source. Anybody tried that???
Using rechargeable 9 volt batteries instead of the regular ones also seams like the way to go, as the regular ones lose their standing charge, as well as their recharging ability over time, and that can affect the self recharge rate of the Captret - Jtc. My best cap is a 400 volt 82 mf. but I have about 10000 mf in parallel altogether.
Some caps are worthless for this purpose.

Caps are unique in the fact that when discharging they have almost no internal resistance. So, they give it all up at once. I could be "throttled" with a resistor for a given current feed output. Feed what is needed and store the rest as its recharging. My problem with the vid is what it takes to run that light. If it stays on with a single cap, many should increase the storage potential if the circuit is putting excess back. Otherwise its drawing from them all equally as they are all partly being charged. That appears to be OU already. Heck if it just sustained for 1 min and ran down I'd be tickled pink.
Different type of batteries have different internal resistances. I've seen instances where alkalines will not work due to their high internal resistance and Li-Ions do fine. All outputting the same voltage.
He really needs to post the schematic & details so others can try it.
It doesnt matter if he can repeat it or not.

Yes they will work

They will work but you have to bring down the internal resistance that the super caps bring to the table. The only way to do that is to parallel them and halve the resistance much like you do with resistors. LaserSaber said that it took 3 super caps in parallel before the circuit started to work. So thats a 3 to one ratio...

What makes me wonder now is that super caps are much like batteries. What if paralleling batteries could also be used in this method? Or in fact if thats how batteries do work in parallel. This ringing is a powerful tool and we should learn to utilize this method to power our electronic equipment.

Hello All.

@Jbignes5
That sounds like something we should all look into.Do you know if Lasersaber ever posted any schematics of his build??Without them it would be like shooting in the dark If you know what I mean Wire size/ how many Toroid's/ .Your Ideal on the Super cap's sound's very interesting indeed.Thank you for sharing. Tec
Happy New Year To All. Tec

JT Ringer

It will work with super caps it is just you need many in parallel to lower the higher internal resistance that the super caps have. LaserSaber said that it took three super caps in parallel before the circuit started to ring like just one of the electrolytic caps took to work the circuit. This makes the capacitance huge when using super caps but lowers the voltage capability of the circuit. With electrolytic caps you can have less of them and more voltage capability.

Hello All.

@Jbignes5 After watching the video a few time's and seeing him throw the super cap down on the work bench it sure lead me to believe that the super caps wouldn't work I am not saying you are wrong Just that's what the video lead me to believe Thanks for the info. Tec

@Vaporizer Like you I would like to see a schematic of the JT Ringer .I do like Plengo's Captret Tesla Switch circuit His voltage has been going up the last video he posted he now has two test's going interesting If you have the time take a look and let us know.

Happy New Year To All Tec

[Jbignes5]

Well it will work with super caps.

Hello NickZ & All.
I watched that today.Blew me away looked like the 1 inch toroid's stacked together the neat thing was that it would keep running after he unhooked the battery's just on the radial standard caps.he also stated it wouldn't work with super cap's & that you had to reapply the battery for just a second or two every now and then or it would stop ringing. But sofar except for Plengo's circuit that's as close has I've seen a self runner come.NickZ Plengo Is doing something right up your alley He is on YouTube It's Called Captret and Tesla Switch Check this out !!! He May be doing some that will give you a Ideal on what you are working on. He is also on Overunity.Com. Look for him There.Happy New Year Everyone. Tec

I watched the Joule Ringer vid. Seems kinda odd. That cfl is gonna need 200+ma and abt 400v on the output to light. Yet the circuit didnt die when he got to 1 cap? The stacked 1" cores is a lot to ring back mass wise. I wish he'd just draw it up so others can try to replicate it. That isnt hard to do. Most cant keep a single LED self sustained pulling 1-2 ma even if the whole circuit needs less than 1 ma using a low power 555. The pulse wave form did widen showing a frequency drop, but seemed to stabilize.
If he cant repeat it...ok. If he wont post the circuit details no one stands a chance. I'll leave it at that.

[NickZ]

@ SkyW:
Nice to see you back. Was wondering where you went off to... That video caught my eye too. So much like what I'm working on, it gave me some hope, to continue on... I knew there was something to that effect, too. Wow, is all I could come up with.

[SkyWatcher]

Hi folks, Wow, lasersaber's circuit sure caught my attention there. I think this is along the lines of Steven Mark's TPU. The high farad super cap. is not allowing a quick enough ringing action. Hi NickZ, I've been building an Adams motor, though I was thinking about an led light system at the same time and it looks like replicating lasersabers ringing circuit might take priority. Hope he posts how he built it and has it wired.

Lasersaber

Guys:
In case you haven't seen it yet Lasersaber just came up with another video of... I forget what he called it but, you should all check it out.
He lit a CFL using just some caps. Just one cap... Ha! It's similar to what I'm working on, but I'm using a Captret - Jt connected to Leds.
In anycase, it blew me away... Thanks Laser...

Wow, that a respectable output voltage with those winds. It would be way less with 1.25v. If you want a higher voltage...more secondary winds...current will be less, but most stuff we are using doesnt seem to care much as long a voltage is there.
Jenna had stated that on the secondary 7v per LED. That should keep you from blowing them starting out with to few.

12 Volt JT

Hi Tec & all.
Glad to hear of your success Tec.
Is that one of the 3" from the place you listed above?
Also, what resistance was used for the base and how many winds on the core?
I've tried the MJE3055 and I like it.

I tore down one of the new smaller spiral 13w cfls. I tried it on an untuned circuit and it looks promising. Good even illumination brighter than the 9w "U" and I think it may be brighter than the larger 13w spiral. I was hoping for this from the shorter tube length.

Hello Vaporizer ans All.
@Vaporizer Yes That's the 3 Inch from BGmicro. The variable resistor is a 900 ohm. My Primary is 4 and 16 winds 26 agw on the 4 and 22 agw on the 16.I used a 5.6 ohm 5 watt sandstone resistor to protect the transistor.The secondary is made up of 6 conductor 22 agw wire about 15 feet long it has an output of around 215 volts. I plan on replacing it with 28 or 30 agw wire.any Ideal on the how many winds I should use? I am going to make another and try to tune it better. Included a picture. I am glad to hear that your smaller bulbs are doing well Tec
