Joule Thief

@all

I still have not build a AV plug , to tell the truth i have no clue where to start.

Any recommendation would be great , i want to try it on the tube .

Diodes to used ?

jonnydavro showed the circuit plus the av plug:

At minute 1.32 he goes into the detail of how to make the av plug which is his 'detector'

i was googleing and couldnt find an answer so i thought maybe somone here would know.  if you know your circuit needs a 1h inductor how do you measure that? some of the circuits online will show you needing a 10uh or 1h inductor which is a 1 wire transformer essentially but if you make it at home how do you measure?

by the way i found this the other night. tesla developed the joule thief in a more complex manner but never the less patented it. its a rather interesting circuit. notice he has one wire linked to the main circuit to his florescent, i recalled the florescent needing a "touch" to activate sometimes. they actually had this battery powered off of a small laptop looking battery pack.

Check out this one!

Stprue I have been following Dr Stiffler's work for quite awhile.
His exiter circuits are really amazing.
I have made a few videos of exiters I made using his circuit.
I even made a couple videos using a JT to run his SEC exiter.
I would highly recommend replicating his sec 15 circuit.
It can be made in no time for under $5 in parts.

But I just wanted a circuit I could call my own lol.

@Xee2 I tried as you said with the plates.
It's just like you said it does extend the field range.
But I couldn't get the lights as bright using the plates.
But I havent given up yet on it.
Adding the extra coils inside each other does make the lights a light brighter and the current draw only goes up around 2mA per coil.
I'd like to make around four coils inside each other then use the plates when I'm done.

Thank you.

@crowclaw,

  Many thanks for clarifications; utilizes more of the available energy, and now clear to me regarding the load.  Diode considerations also noted. 

  Me, I'm basically just waiting around for some developments with the JT;  "heat and light" from the JT w/secondary thread.  Kooler's circuit is right there, with more to capture.  Gadget's circuit is just amazing.   I spent like 6 hours yesterday going through that, the hairpin thread, and others. 

Many thanks; and best regards,
Mikey

So stew,
The battery run time? Did you test it?
Is it only 2 hours?

I made jonny's version of this and got the av plug to show a weak response, but the oscillations only lasted a few moments, which was long enough to show that it works, but also to show that 1.2v is a little too weak, and  as lidmotor said, it really works with the 5.5v charger.

Thank you for the confirmation,

jeanna

hello Jeanna, I have not done a duration test on the battery as I do not have all the components yet but I will take your word that the battery lasts 2 hrs! but coherence energy does have effects that you may be able to use to re change your source.   NOT OU....just efficiencies!  I'm not sure what you mean by a weak response on your AV plug???  At this point I have tested the circuit with a cclf driver...some as koolers! and I can get a decent response with it!  a crap efficiency circuit. i will post my tests when I get the proper components!
