Joule Thief

[jeanna]

Yeah, I am concerned too!

@Gary,
I made 2 pics for you from Bre Petit's pdf on the joule thief from makezine. The schematic is the one we have been using since I posted it before, but since I cannot find it I am reposting it. The other is the 2 photos of the wire details when finishing winding the toroid and putting it together.
I could possibly post the pdf, but it may be too big, so here is this. I hope this helps.

You are right gadget is missing , i am fearing for him , but he may have pc issue , like me and Jesus .

@resonanceman

First i would like to say that i have included in my post all the details to get this jt up and running , i my self use the very basic jt schematic
and now get over 1000 volts .

I don't feel like repeating , not because i don't want you guys to get it . I am convince that you will get it only if your heart is in the right place
since it is as simple as 1 plus 1 .

In the last week i posted many thing to understand , they are all good info , sorry if you don't see that , then you are missing the point .

Facts , jeanna tried to show jadaro . i took time to make sure jeanna got it right ,and btw i am really proud of her all info are included in the first 150 pages. Page 125 there is a picture of the mk1

please don't discard info because you don't understand , this thing is so simple , i have a hard time believing its that hard to get.
So replicate for now . And never test result with meter only because you may not find it , it take some faith .

Here's an interesting thought:  What's happening to electricity on the way back to the battery?  This circuit terribly misshapes the flow of energy from the battery...is this going to effect the battery?  As in, what type of electricity is flowing back to the negative?

I read one post where spikes from a battery where charing capacitors in such a way as to create a voltage larger than that of the battery source voltage.

Speaking of breakthroughs: ..has anyone considered pulling their juice from a homopolar motor to power the joule thief?  or how about powering an hpg with a jt?

Also - I'm worried about these toroids emitting waves ...they are oscillating at high frequency, they may very well be emitting radio waves - if powerful enough, they could be in violation of FCC laws.  Pirate posted a video of his toriod emitting AM radio waves.

In my mk8 on one coil a 470 uf reaches 35 volts in 3 sec. so i have 15 more coils ?
