Joule Thief

Hi everybody,
I just posted more scopeshots and other info on localjoe's EB thread. I chose that one because I am putting probes in the ground and that is what we did on that thread for nearly one year, so...

that link ought to  take you there.
I uploaded 2 movies of the scopeshots too. They are too large for the regular place.  The link is on that other page.

Now, back to my joule thief!!

Yes that is it. If you watch the Spikes of voltage will go way up when you have it in tune.

Thanks, but now, I want to know where the scope is.
You have the rheostat across 2 pickup wires... and where is the scope connected? Right there too?

Hey Art,

try this:

it is reply 2274

a scope of a EB.

edit
the markers are slightly too close. I probably was 2.4MHz not 2.5MHz. Either way it is there today too. And on the copper to copper today too 2.22MHz!

maybe im just looking at those EB scope shots crosseyed but i could swear i seen pulses on a sin wave pattern as if the eb IS getting its power from the magnetic lines of the earth! if that is what i think it is then your gonna get 2.4mhz pulses and they will always provide current (during the pulse) but will be like waves of an ocean first high then low then high again.  jeanna you think im right or wrong or got another idea? you kept up with the EB thread more than me

I tried to  post a picture of my new coil a couple of times ..... it  just  times out  ,


I made this  coil  hoping  that it would help  me  get a handle on fine tuning my  LMs     So far it hasn't helped much with that.

This  coil is  300 ft of  red radio  shack  wire .
I  tapped it  every  30 ft so I have 10 connection pegs on one side of the reel .
It turns out that if  you connect B+ to  one of the pegs ..........and    connect  the  C leg to a peg  on one side and the E  wire to a peg on the other   you  have a one wire JT.

In general  the one  wire JT  drew less  power if  the  connections were all together . 

I got the most  voltage from the secondary   if I  connected from  pin 1 to pin 10 .    Yes ..... the  3  pins that   were  used for  the  connection  to the  transistor   are  both  primary and secondary

yup.

And after I fixed the loose connection I got better voltage. But lets talk about this on the other thread, OK?
I posted a bunch more pics and 2 movies today and they warrant a bit of talk, I think, but over there where the talk is EB.

@Gary,
I am assuming those letters you are talking about are on the pic you tried to post?
I had the same trouble earlier...
Please keep on trying.
