Joule Thief

Hi all

This was posted by Room3327 back in January on the Towards Realizing the TPU thread, anyways, since we're playing with toroid coils I thought I'd mention it on this thread.

I don't remember seeing this mentioned and if I did miss it then sorry!

In this thread http://www.overunity.com/index.php?topic=5486.msg151756#msg151756 Room3327 gave a pretty good example of how Tesla's 381,970 could be driven by an electronic circuit.

I'm posting a basic idea photo of what I'm seeing as far as the JT is concerned, any constructive ideas as far as circuitry would be appreciated.

Thanks,
Paul

Just for clarification, I've put my coils at 90 degrees to one another.

@Hazens1,
Thank you for that info on the 555 timer, I didnt think it would get to such a low voltage, but then I have had another thought, as LAPTOPS have been designed to run on ultra low voltage and current, just maybe this could also be a source of parts to use with the Joule Thief.

Going to keep my eyes open for junked laptops for now on.

Thanks for that 555 info Hazens1, very good stuff that.

Hi Goat , good one , thanks for the reminder , this is a picture of my Tesla pat test toy. Its all in this tread but most don't have time to read the tread in full , i do think it its a good read. but there you go.

I used 2 jt at 90 degrees interval , got 60 volts from pickup coil output ! But there are not tuned or sync. i may need to look at it , now i know how to fix those issue.

Thanks for the reply, in Room3327's description he mentioned that this Tesla patent mimics Tesla's motor but without a rotor, but he mentioned Line1 and Line2 being 180 degrees out of phase, you mentioned 90 degrees? 

I was trying to figure out how to replace the dynamo with the JT circuit to feed Tesla's circuit with the same wire hookups as in the patent.  I mentioned two 555 timers in the picture but that was only a thought, is it possible to use only a transistor as the switch to feed these 2 lines in 180 degrees out of phase as Room3327 mentioned? 

You'd have to look at all his posts to get the whole idea of what he's talking about.
