I am pretty much worthless. Worked so hard yesterday and the kids wanted to spend time with me last night so needless to say I never even picked up a meter.

Work is really busy and I will try to get those numbers tonight. How many turns do you have on your pickup coil? And what type of wire?

@gadget if your ill

well my friend you need to advance your reserch to solve this problem ... 

for those that have not noticed i have droped much of my electric work lol   anyone know why ... 

you all have an ora ... lol

tesla designed the sheild ..  wich goes right along with  many things ... 

shock ya rocks... 

tune in  tune up amp your ora ...  beat illness...   

btw gadget im sure you have all you need lol

im selling rock sets to ballance oras 

all must digg back to move forward ... 

you will get it all in time ...

ist!

when the sheild is worn it is a guideing concuessness light beam you are in ....beam me up scotty!!

Ah Please spend time with your kids. That is a verrrry important and wonderful occupation. And, very soon they will be in their thirties. 

I have 240 turns and they are in the MK1 fashion.
The wire is from newbie wire and is 24gauge magwire.
See pic below. (Both primaries are there. I use the one up top.)

My notes declare that when half done, I had 275V @7.2KHz
At this time I was using a 79ohm resistor. BTW, yesterday I was using 2k2ohm.

I am under the illusion (delusion) that while I may change the ultimate output of the voltage with a smaller value the kind of change in voltage I am talking about is independent of the resistor value.

So, with that 79 ohm resistor I got
275v @ 7.2KHz --on the first half before I finished turning it. I had
131volts @ ~17KHz -- when the turns were finished.

Later I messed around with various base resistor caps and different resistor values.

These figures were with a less vigorous primary. At the time I had this
3T,4T,240T

Later I added turns to the primary to 3T,20T,240T
got zero oscillation
Then backed off and used
3T,10T,240T
using a 150ohm resistor and got
246v  4.76KHz

This is still less than the original amount for half the secondary which was 275v for just the half. (I think it was less, I see I had a higher value resistor then.) In any case it is a not twice which is what I would think I should have.

The shape is improved and it is really improved with a cap added, but the voltage also goes way down.
(xee addressed this yesterday.)


So, maybe this helps.

I will be pleased when you can get this information to me, but do the important things first!.

thank you,

jeanna

BTW, this lights a neon. But I find it disturbing that I have no additional voltage indeed I have less, so why bother? Or how can these be added for more voltage?

Can you explain to me how to measure half of the leg? So I can replicate you setup? Can you please also explain what you have our scope set to? Div Probe etc.. etc..

I am using cat5 eth cable for the primary. Its the only thing that I have got to work correctly with the high flux toroids from CWS


Thank you!

The primary is made of cat 6 tele wire. I think I had 6 colors. I don't remember now. 5 or 6.

Maybe the pic will help with the half part.
The MK1 is made in 4 directions straddling the primary. so it goes up then back down (this is the first half) then it jumps over the primary wires, then it goes up then returns down again. These last 2 directions comprise the second half.
Each of these halves gives more voltage than both halves when connected.

About the scope,
I put it on T/DIV and push the down cursor until the volts/division go as high as they can. Sometimes this makes the wave very hard to see; but it gives a truer version of the voltage.

I return to a good distance by clicking the up cursor.

The left cursor takes me stepwise to a lower frequency per space between the markers. Without bothering to change the markers for the moment, I click to the left until the whole wave is in view (LOL) This gives a chance at viewing the big picture.

Then I click the right cursor. It takes a moment for the wave to be discerned and so it may take a little time to see the progression to a higher frequency.

When I can see 3 waves in the screen and the next screen is only one, I go the the last screen with 3 and place the markers on the wave . Now, the frequency reads the actual frequency of that one wave.

@all,
I have made a couple of bookmarks on my browser. one is to the main "Joule Thief "page with 3 sub headings.
http://www.overunity.com/index.php?board=118.0

The other is to the "Other New Battery Systems" page.
http://www.overunity.com/index.php?board=13.0

I find it is faster to have the link that goes directly to that header page than to navigate to it from here.

From there it is easy to check to see if someone has recently posted to one or the other eb threads.
And remember, the one started by localjoe is historically the first one. Its whole first half is about help and troubles and patents etc dealing with ebs as probes in the ground.
