AC from Joule Thief Secondary/pick-up

[jeanna]

at 2.05 vdc it had spikes of 80vac at 5.31 khz
but i also have some of those 3'' tor-23 from alleletronics and they spike at 360vac (75vdc) and still don't light my led's of the 265,000 type

Hi kooler,
good job !
I am curious, how many turns are on your aircoil?

And, how many are on your tor-60 (the big one is tor 60, right?)
I use the tor-23 for the xtree and lots of things because I like to start with the higher frequency.

What is the transistor and all the rest?
Maybe we can get your big toroid to light those very big leds.

One thought, did they ever light up?
Do you have a small circuit set up to test a led?
Actually, if you do it quickly, you can hold the led legs around the flat + and - sides of a 2032 watch battery and squeeze to check a led to make sure it is not blown up.

Those big leds should definitely be going on.

Did you remove the basic JT light?
That sucks tthe power from the little switch circuit and sometimes keeps the secondary from doing its thing.

i just thought it was interesting.. but i am weird

about as weird as the rest of us!

oh jeanna don't fear the scope you got i was running 1600vac (458vdc) thru it for 10 min's no current of course

nice... thanks

my air coil was 7 turns beside itself and 3 layers    18 awg speaker wire from the shack 
(radio shack) almost 24 feet...it lights these 265,000 mcd leds half brightness,,8-10 of them
1k 1/4 watt
mpsa06 npn transistor  (not good 4 low volts.. i know) but does show sharp kicks (spikes i mean)
http://www.allelectronics.com/make-a-store/item/MPSA06-HM/MPSA06-NPN-TRANSISTOR-HOUSE-MARKED/1.html
it showed 1.16 khz and there is no led on the collector side of the transistor...

and the ferrite was a 86mm tor-60 sorry, sorry for saying tor-23
drinking is bad for you .......
but 58 turns sec and about two inches of the ferrite used for the jt circuit.. stanard fashion give 75 vdc.. 360ac and it won't light the big leds i got at all.. not even one..

Thanks for all the info.

The only thing I am wondering is if they or one of them got blown?
I think they blow out more easily than the other superbrights.
360v will blow out 10 leds even in series. That is 36v each and they cannot take that.

Did you try lighting a neon?
If you have over 150v on a secondary you ought to be able to light a neon.
This would also prove that the figure is correct.


The other question I have is about the 75vdc.
Is that from a dmm?
The 2 numbers don't work together. 75vdc is not 360vac no matter how you cut it.
Are you reading the scope on peak to peak? I am assuming you are. But I am also assuming the dc figure is not correct. The dmm cannot read these volts correctly.

I think you almost have enough there to light a real fluoroescent tube. another 20 turns ought to do it. xee2 lit one with 80 turns, but you need 450vac.
Try that too, maybe.

I post my wireless effect here because it's more AC from secondary.
Here are my 2 new video:

Kamax,
Those videos are great!

I think you are looking at the ac from a joule thief and I appreciate that you are sharing it here.

I would like to know how you made those coils, if you did .
Do you know anything about them?

And the pipe is interesting.
In the discussion about the fact that you do not need to connect the other end back to the circuit, Tesla said you could put a piece of metal, and I think he suggested aluminum, onto the wall, and the light would work just as well.
I think you have shown this in 2 ways.
1- with the wall plug ground.
2- with the pipe.
I wonder if a piece of aluminum on the wall will work as well as the wall plug ground.

thank you,

jeanna
