Joule Thief

While I wait for ist's video to load...
I will report the same kind of loss with the TRM that I had yesterday.
43v for one section
now I have finished another section
43v, so basically the same, but the 2 together only make 50v.
I will try again, but the I left the scope on earlier and the batteries ran down. so tomorrow will be the earliest to compare these data, but it looks like there is a funny thing here.

Now, if I could understand phase a bit more, maybe this is just phased not so well.
Maybe on a larger core where the frequency was lower to begin with I'd have more leeway with the base resistor.

Or, maybe there is another way to tune this.

Maybe there is something else like another inductor that could tune them together better...

I will try to get 4 quarters in the center, but maybe there is only room for 4 with fewer turns.

OK to ist's video. 3 transistors! wow ist.

I BET THERE LOTS OF WAYS TO TUNE THIS ... 

YEP THE 3 PHASES ON 1 COLLECTOR IS THE COOL PART ... 

JUST FULLLLLL  MILLIONS OF SPIKES ....  LOL

all of thease scope shots are from my 6 lap accelerator / collector coil

Hum, that is the reason i insisted on the diodes . Doesn't the scope show you that ...

Now you know that changing the pickup coil changes also the impedance and freq , i must insist again , the only logical way to determine the best design is to tune them to there maximum efficiency with the base resistor , that way you compere apple with apple . so connecting 2 pickup coil together will change the freq with a change of freq a change in voltage also happen ...

@ist

To see the holly ghost (the spirit freq) you need 2 freq at the same time .

I wish you could redo the last video , with a proper scope set up , i am sure it will help everyone including your self .

You may get more responses ...  even if it needs a dead battery.

Or your scope can't see it ?

indeed mk1

but this is only npn   the pnp unit that will be SYNCED   THEN RUN THROUGH 2 ACCELERATOR TPU LOOPS

is not built yet ...   

sheesh bro ...  im a trying ...   

ist!

but lets get this unit tuned properly wich means i need better control over the shifting freq...  and the 1$ ramma chaser just wont let me varrie that aspect of the coil yet ... 

plus its the first run on the unit ...  i think i have done well enough for 1 day ...



night all

peace!

sheesh i forgot the best pictures      ok now im done with the camera for a bit 

same coil scoped ...

BTW MK1  MY COILS WILL WORK JUST FINE THANK YOU!!!  LOL

BEATS THE HELL OUT OF A JT .. OR A MK2 SERIES COIL ... 

I HAVE A SIMPLE DESIGN I WILL EMPLOY 

AND ITS ALREADY POSTED BY ME OF COURSE ..... 

AND PROBALLY LONG B4 THE MK2 SERIES  COILS CAME ALONG ...   

[stprue]

Good,

it is complete... I took mine out so it is no longer complete! 
but not right?
do you mean no voltage is now less than it was with one quarter?


Are yours the hazens style? I remember thinking they were.

OR, by x2 do you mean crossed over and in 2 directions total?

We will see. I am making mine with both primary at 4 directions and also the pickup in the same 4 parts or quarters inside where the primary left a bare spot on the toroid.

I am rewinding in separated sections.
I think the MK2 directions are for this sort of thing. -- You make the turns then figure out which combo works the best.
I am making a code on the wire ends so I can tell them apart.

Yes the voltage went down to 31 volts and I think because the base and collector coils (Hazen style) can only be set up for one direction but this TRM design requires dual directions so an x2 style base/collector ciols is required....I think!

I'm not sure on the perm and other stats of the biggo but I had really good results with only half wound biggo.  I want to set up a small goldmine torroid the same way!  I should be able to get some good results with that.
