Joule Thief

I think it was Mark who made that drawing. The patent is all over this website. It is one I was thinking of playing with too.
In it, Tesla describes that he is making a rotating magnetic field and it is that movement that is what makes the thing so powerful... etc.

It is wound like the x2 primary,  as far as I can see.
Wrapping over and to the right on one side then crossing and starting under and going to the left (or maybe the right) on the other side.
Then done again at 90 degrees from the first one.

I agree. That will tell you a lot cheaply.

thanks for spilling the beans, I am looking forward to this.

Yes you described the idea much better then my quickly typed babbles.  Thank you.  Let me know if you find the pic...if not I will scan it and post at some point.

Here is the biggo I was telling you about and the tesla aspect would be made inbetween these base/collector sections, but like I mentioned I will make a small one.

@Jeanna

oh yah I forgot to mention firefox is working better here for me

[innovation_station]

looks verry nice stpure ..    but that is to be expected ...  lol

now cuz i am the villliage idiot lol   can some one help me with a super simple transistor  pulser with a cap that fils and drains ...  and cauzes the timeing of the transistor to switch ... 

if ya know what i mean ...   


i want to use a small transistor to pulse slowly and i in reward for this will teach you some thing you will like ...

ist

as well your design will be used with mine ... 

this is pnp switching on my 2 10 640 1"   now    look at how i tuned it ....it is not tuned to ac sine waves   it is not tuned to highest peek voltage ....  it is TUNNED TO THE most RIPPLES AFTER THE WAVE...   WITH A 1K POT  and this coil i can only tune in to 3 peeks .....  ok   




just cuz a single pules kick is getting OLD  and BORINGGGGGGGG... 

take a look at these scope shots .....

@ the_big_m_in_ok & Mk1

Does anyone know how this is possible?  The electrons are leaving the negative electrode, but where are they going after that???  They disappear?  What else?  The circuit works doesn't it?  I know of no physical phenomenon that can do this.

Neon bulbs are DC devices. Only the negative electrode glows. When driven with AC the glowing electrode changes back and forth 60 time a second (too fast to see). Glow is caused by electrons jumping between states in the neon gas.

xee2,
I have been wanting to ask you about halogen bulbs.
What is required for a halogen bulb to turn on?
I looked it up and all I found was places to buy one!
I am sure they are made to work at 120vac, but is there not a transformer of some kind?


thank you,
