Second Stage Joule Thief Circuits
« on: November 21, 2009, 08:06:51 PM »
I was asked to begin this topic for work on the second stage joule thief circuits.  Our first joule thief topic has grown to monstrous proportions at over 1000 pages and well over 10,000 posts!

There is still a lot of good information there as well as on the joule thief diagrams topic where you will find schematics of some of the devices.

Let's see what we can all accomplish here on this topic.

This is Gadgetmall's 1.5 volt JT heater circuit.  Gadget has applied for the OU Prize with this device.  Good luck Al.

Thank you Bill . We could have started the thread but you have Moderator privileges and can edit out old post and stuff  plus you have the Most popular thread on the planet :)

I will start the post by posting My AA battery heater .light circuit using boostcap as the secondary power source heating and burning nichrome wire + lighting 1 watt of leds . Now this is based on the original Joule thief with a secondary .This Schematic is Self explanatory and Simple to make with lots of room for improvement .  I have a 1500 farad ultracapacitor that i will charge with this circuit later in the months and also improve upon the winding of the joule thief circuit . I am dead set on using 1 to 1.7 volts for the input on this device . others can use 12 volts but 12 volts is bulky and there is ac hance of noxious fumes and risk of explosions also with lead acid batteries ..

Hi Gadget,

Have you tried 1.2V rechargeable batteries? I agree 12V car batteries are bulky, might fume if the current is too high, but doesn't bedini say that the bigger the battery the better for OU? Supercaps are great, but not everyone has one.

This all seems very cool. I have little to no experience with JT's.

How fast is the boost cap fully charged? And how did you check the 3500amps? Or did you discharge it through a conventional load?

@all

First thank you Albert for the heater , and those great cap , i know from the beginning that the jt with a secondary was making so much energy that there was about no way to catch it all ...

ps . once you learned about DR. Stifler maybe the could be a way to tune a bunch of antenna coil to the toroid and get even more , wireless power ?



Ok , every one here we take the second step in the jt development .

First we have seen led light then cfl even Bill's four footer , gadget's Tv disruptor , Gary the man that like to walk a different path , Jonny and Lidmotor have made great motor not unlike the old jt , Etc ...

I have to say i forget some , but that is a indication of how much we have done in a short year , Congrats everyone !


Now the Second Stage Joule Thief , Aka SSJT , will be for going beyond that , A second stage could mean many things ...

Its all about ideas .

I have some my self, i will fully explain .

I also believe the is better toroid then the one from goldmine , i wish we could measure those i go one that is way above all the others , lets just say one that one the led make a high pitch noise , and i burned a set of 5 X 5 watt luxon led in parallel from 22 turns secondary ...

Some ideas , please everyone fell free to make them known .


First , How about simply making a second jt work from the first one , running slower then the first one giving us time to charge cap to run the second at slower speed .

Second , we should take advantage of the high voltage from the Flyback jt
to explore the tesla hair pin circuit , and spark gap , after all this is a static charge , it should be possible to charge a plate to the opposite of the surrounding static environment to develop greater charges.

I believe it could also , fly a Lifter .

But now please , Its time to speak , in the Jt tread , like any idea , nothing is to crazy other wise it would not be so fun .

I fell that the jt treat could address the basic mod we make to the jt , and still post to help new people to join in the fun .
But now the attention has been cultivated and starting on page one is less dissuasive for interested people .

Sorry again , for my English (French Dude)...

Gadget,

Can you take a look at this circuit. I must have something wrong, probably with the toroid primary or secondary connections,

http://globalfreeenergy.info/imgs/gadgetmall-circuit.gif

The 2 dots by L1 & L2 mean they are on the same core. L2 has twice the windings, and hence 4 times the inductance. I had no idea how much inductance, so took a guess, but that's not the issue right now. The issue is that I don't fully get the connections on your toroid in your drawing.

Thanks,
Paul

That is a basic Jt , with some mod by Gadget , it doesn't show any secondary...

Just put one on the toroid anyway , gadget mod will help you in running the jt in resonance , and adjusting it so.

The cap took approximately 14 hours to charge with a Standard Jt . the 3500 amps is the Specs. for a Maxwell Boostcap . And yes i said all along this thing burns lamp cord into but only a few days ago i decide to try Ni chrome wire from a burnt out heater . I discharged 4 1/2 minutes from 2.6 down to to a voltage of 1 volt for an experiment 2 .During that time the coil of Ni Chrome lit up brightly and i even lit a cigarette with it :) It was very very hot and i could feel the heat several feet away . All the details are available from the experiments in the last 10 pages or so of Jule thief thread for you to replicate . SUPERCAPS are not ULTRACAPS paul .

@Mk1 . I would like to know if you have a source for that toroid .  I have several large toroids and one that IST has the BIG 140mm ring in route plus some 3.3/4  inch GRAY toroids . I also have some black 2 inch as well . I guess we can start by you describing your specific winding on your device the LED blower ?

@gadget

Its the green gem , the very first one , i guess you remember , it  came from a dvd player i think...

We really need to find a way to test those.

ok just to clear this up b4 some one does something stupid...

i do not reccomend the out put of the large 12vdc unit EVER BE USED AS AN INPUT FOR AN ADATONIAL STAGE!!   no!

stright to invertor for output ONLY!

ok

glad thats done   the big core i used was 10000u this is important as i have read ..

crazy world .. that is truely all i know ..  its a wild place ..

I think it's a good idea to have the circuit clearly drawn before having people replicate it? That's how the mylow's and such waste peoples time, lack of detail.

Gadget, did you see my question? Thanks.

you have 1000+ pages ...  already if your a beginner ... 

master a basic jt first ... please rejoin here ...  then we can move along .. 

insted of old ground !

It is a new circuit. Gadget just posted his circuit, but there's a serious problem with his drawing in that it's unclear. You don't want people to know exactly how to build gadgets circuit so they can verify his claim?

Paul,

I am not able to follow all the syntax here today, but if I am to follow just the PLowrence drawing I would say you did not make your basic jtc correctly. I think that is what ist is trying to say here.
We all will help you to do that on the joule thief thread so please follow me over there now.
