well i see the french fry and candyland war is still going..
but more on topic.. the video i posted last night was at 0.657 volts and this morning it was at 0.871volts..
and now it is at 0.852 volts.. it was running at 104 ma draw so i think i will reconnect it to the meter to see it the draw went up or down since the light is still going way passed 40 hours

Good work Kooler !

You are right , war is stopped since there are too many civilian casualty .

That is it everyone , you like ist keep him.

I was raised to stand for what i believe , sorry am i bad .

Many people think like me , but are so used to be victims they don't even have the guts to do anything about it ...

I have worked on this tread to make it what it was , now its ist land.

Quite sad .

I will not border people here again , you have fun ist .

To the others , i tried to clean this place , sorry ...

Now you will have to live whit ist ...

Shame on you !
 
You want to know what i did here i made you guys put secondaries on those jt , that is what i have done here , and ist invented earth .

So i lost !


@resonanceman

If anyone beside me had any backbone this would never have happens.

Sorry you don't see it yet , do anything worth mentioning and he will tell you its his work .

Good luck .

This tread is dead to me now. He destroyed it for me he will do the same to everyone.

We have come a long way on this thread and the progress seems to be endless so we should all focus on that and ignore everything else!

You are mistaking being reasonably  mature with not having a backbone.

If IST thinks you kicked him .........he is    going to kick  back.

If  you  think  someone  has kicked you ...... you are  going to kick back

Neither of  you has the maturity   to stop

Neither of you has the  wisdom  to see how  pointless  it is.

You  both  have some talent building things....... that is what  should be  shared here.

I would  like both of you  to go back  over the last few pages and look at what   has been posted.
Look at your posts  as if someone else had wrote them
What would you think  of this person?

gary

Edit

I am not  going to help you trash this thread.........so ........this is my  last post on the subject

so back to building ... 

i found a bunch of caps i forgot i had  probally work good for banger caps .. 

100vdc 680 uf i have bout 100 or so .. 


so i will likely use them at around 50 volts ..

so a simple way i can build this controled  with materials i have aquired from the dollarstore  is to use the chasers to discharge the caps 123 123 123   useing 1 cap per channel  and useing 3 chasers ..   

thats only 9 caps .. and i could possibally only ever drop 2040 uf per cycle of 3 chasers by the 3 cap batteries .  in 1 revolution ... with 9 bangs ..  thease chasers run fairly fast tho ...  however i doubt the 3 cam bords could not keep up ..

espically with  buffer time ...

the circuit i posted in the video has run for over 50 hours and the volts on battery are staying on 0.850-0.856
it started out with 104 ma's draw so i checked it after 48 hours and it has went from 104ma to 7.58 ma draw..
so that tell me why is running alot longer than i thought.. so i got a full charged battery and stuck it in and it had 110ma draw
so then i put a dead battery in it with 0.38 volts and it pulled 1.4 ma's.. the led is still full brightness..
so it is backwards from the regular jt that draws more as it dies..
and i still don't understand nothing about circuits so i might just drop this one..

Yeas, I look forward to you semi-final design video, if you don't have time, just say what the part numbers are like you did in the last one, I can probably figure out the schematic that way.

That's a lot for JTC. ..maybe there's something going on at the transistor.

'Tuning' this transistor is relatively easy, just attach you ammeter leads on the C and E connection and measure the resistance across it and you apply a base current / voltage.  I do this all the time, ..there can be many extra K ohms there and still turn it on.  I was attempting to make a variable current device which would decrease resistance and voltage source decreased, that way the transistor could continue running beyond the 'point of death' voltage ...

I was going to do this with mosfets, but they're all quite senstive, I haven't been abel to get good readings on them.

Thanks for all the support !

@all:  Here is something I am figuring out about the Joule Thief.  With my current setup, it does not matter what the input voltage is, I still get 120v out.  This is why a 1.5v battery drained to .5v can still power an LED.  This is very interesting. So what do I have to do the get more voltage out.  I would love to power my Newman motor with only 1.5v input.  My guess is the number of windings in the larger side of the coil.  So I will definitely want to try an automobile's ignition coil. 

I believe you only need enough to bias the base-emitter junction of the transistor.  And perhaps the speed at which the transistor can be switched on and off plays a factor in how much I can get out of a JTC.  Hmmmm...............................

I have included a schematic of my setup, which seems to be the best efficiency (voltage wise, most bang per volt).  I did not include a voltage value, because it seems to not matter.

detrix,

   Less turns on primary and more turns on secondary, you can get over 1kv. Another example is winding three coils on a 2.5 inch toroid core, 2 turn primary and 10 turn secondary (JT), with the collector at 80 turns.  Those little flash camera circuits also put out over 1kv.

Hi Slayer

Always testing the main coil  and today i could get a nice very stable 2mm long plasma arc with about 100 ma at 12 volts.

What is remarkable is that the Arc does not appear when i turn the current on. I have to light my CFL tube first   (by contacting the main coil)  than i have to slowly get away the CFL tube until the light desapears  and only than the plasma arc is on.

It seems to be the necessity to turn the coil outer power on.

Very interesting

Can you explain why we need to turn this outer power on ? And can somebody explain me what is the power in a plasma arc.  The smelling of ionised air is quite strong and depending of the gap distance it can burn my table. !

Regards

Laurent

Hi detrix what transistor and diode are you using?
Thanks
