like your charts ...pro like you know
reminds me of ross perot.. man i wish i could vote back then....

oh do we know what diodes tysb3 is using on feedback

There is not much difference in diodes at low currents, so I think it does not matter what you use. I have looked at his circuit and think it is very clever, but it does not seem like the diode across the base coil is needed. I was tempted to build it just to see. But if you are building one, maybe you can see if removing it makes any difference in performance.

Hi xee2,
I like your explanation a lot.
thank you.

If I can stretch it even more by thinking of the pulses/sec (= frequency) over the wire substituting for joules/sec(=amps) inside the wire, I think it can help the others who continue to visualize this like a strange dc type circuit.

@ArticKnight,
I made my first 2 joule thief circuits ON a magnet as you suggest. I/they worked for a week then stopped.
The magnet had temporarily put the transistor to sleep. I thought it was gone, but some time later after I had taken apart the circuit with the magnet, found it was ok I remember you were there back then, and even made a comment about it.

thank you,

well that sux that i dont remember,... but its cool someone tried it! ive got a particular cuircuit thats kinda like gadgets but simpler in design, im seeing how that runs. right now the voltage is dropping dispite the fact the curcuit is forcing a charge cycle. its wierd.

i am going to build it... and will do all the test i can to my knowledge.. which isn't far..
but it may be after xmas...
which will be the time i make a video of the circuit i have running two of those lights i told you of....
man i be glad when i don't to work 8-10 hours a day so i can do this stuff more...
i need more sleep

out

It is certainly normal to get more voltage across the collector-emitter than the battery voltage. That is what allows the JT to light an LED from a 1.5 volt battery. I have gotten enough voltage to light a neon from a 1.5 volt battery with just the base and collector coils (no added pickuup coil).

It is not normal to get more current out of the collector than is being taken from the battery. I am not sure how you are doing that. Can you post more details about how you are measuring the current?

That is what i thought  ! , I don't know how to make it any clearer . If you look at the Jt circuit  as i posted  and disconnect the bcap an put it in another room  and just have the jt on the table , ok . I use two meters , Double ,triple checked them and they are working properly with good batteries . I simply measure the input current across My one ohm resistor to determine what my circuit draws and leave that ammeter going ,ok , then i put another ammeter across the wires that would normally go to my bcap ,which is the other room and i let that ammeter measure that connection  the result is what you see . It is not normal . I won't say anything else about it , this one is Alex's and he can have a go at it but it appears this is outputting 18 more milliamps and about 2 more volts higher than it is using . I can't explain it but this is what it is doing . I must be going crazy and My eyes and camera and everything must be wrong . I swear this is exactlywhat this jt is doing  and so to further test this out before it goies in the morning i put two 30 farad supercaps on it . the run is or was 1.701 and the charged charge cap was 2.000 and i just put a light bulb regulator on it to see what will happen . Of Courase the run cap charged up to equal the charged cap and has stabilized at 2.00 volts for over 15 minutes without a drop . anyways I have no explanation why this exact duplicate of my other Heater Jts is outputting more current and voltage ? No  Idea  . I am tired . and i am so tired of seeing all these weird things i will put it all in Groundloops hands ,give it to him and let his eyes see what mine are seeing . Have i got some kind of power to make this stuff do what it does ? Has God given me something no one else has ? . Well i will have that question answered when Alex has a look .

Peace and good will is all i ask guys . . Please do not flame me for My Postings . I really do see what i see and i am starting to believe what i see and why only a few can do it bothers me . A lot ! I'm not Crazy i don't think.

Thanks for the response Xee2 . i thought the same thing but i want to know for sure so we will see . I'll ask Alex to post his findings  on this Jt and then if he dosnt see it  i guess ill trash my equipment , but i really think he will see what i see and i am sure My expensive Fluke is working percectly as i said i swapped both meters and they read the same within a micro amp:)

Merry Christmas
