Joule Thief

[gadgetmall]

Don't know what to call this JT ? http://www.youtube.com/watch?v=3q2VnPpvKdI
unless i am measuring current wrong .This  readings are 3 ma in and 21 ma out ! Same way everyone else measures it . this appears as a unique JT . unlike any i have made before ..
Its sent out now and i tried to make a copy of it using the exact same parts last night  .it will not do the same as that  one ? the only difference is parts placement .  I do not get more out than in on the exact replication of my own design . The problem is parts placement i do believe . Or the Transistor gains are different from part to part .I also did not have another wirewound 1 ohm so i measured the new one in series with the battery

   The geometry of a circuit relying on parasitic capacitance is of the utmost importance.  Its your information feedback mechanism.  John Hutchinson built himself a scaler wave inferometer.  He would sometimes have to wait six hours for the device to start receiving and converting.  There is now evidence that the longitudinal waves created on a regular basis due to the magnetohydrodynamic conditions on the Sun are of an extremely low frequency. Six hour frequencies.  But riding the six hour long electromagnetic field change are shitloads of other frequencies that are conveyed by these massive waves.

Gadgetmall,

Can it be that you hit resonance in your Joule-thief?
That would explain the strange Amp-readings you get.
Please watch this youtube movie from Tortuga0303, it is called "Energy Propagation" and goes about resonance in LC circuits;

Thanks for sharing your findings!

A Merry Christmas to you and your family, and by this I also want to wish all other members of this forum a Merry Christmas.

Merry Christmas ! . You know i don't know . I just had a thought . the Black 1 ohm resistor ! Its WIREWOUND and so its a coil in it self . A piece of wire around a ceramic body . this might cause the effect you describe  above and the effect i am seeing  ..It is extremal aggravating that i had it and now i cant do it again  . I will have to find a supplier for those big 1 ohm resistors .

Good start, but you need to find out what's going on with one of your meter readings because it shows output at ~ 21mA @ 2.1V, which comes to ~ 100 ohms. That can't be correct because that meter in current mode is supposed to have low resistance.
