Hi everybody,

I have been unsatisfied with the schematic for the 2 tiered joule thief, so I changed it. Please look at the one below.

I think this is correctly representing what the circuit looks like.

Please note the absence of the second transistor and its base resistor.

I connect the toroid lead that ordinarily connects with the transistor base to the neg side of the column of parallel leds.

One of the secondary wires from this jt toroid is now redundant.
I connect one secondary wire to the pos of the column of leds
The other goes directly to the neg battery rail.

Of course this neg battery rail is not being fed by a battery. Instead, it is being fed by the secondary from the first jtc.

This shows where the circuit really is here.

I found 2 basic voltages.
With the probes on the pos side of things the voltage is 1.2v. On the negative side of this it is 6.4volts.
I will give more specific details on this in upcoming posts.

thank you,

jeanna

hello everyone

hope everyone had a wonderfull easter weekend ... 


just letting you all kno im still round ... 

i will be doing some pancake tests soon....   i will use the pancakes  as powerfull jt coils with the large grey toroide ...  this should prove intresting .. 

as well im linking a bunch of tesla pattends togather to further prove it in his own words ... 

the top pancake will be 1 pulse and the bottom will be the second ...   this is an oreo cookie stack 

and the 2 pancakes will be the same size and gage 4 turns ... 6' 14 ga bifillar

there a tonne of ways this can be configured...   ferroite core is the OREO COLLECTOR

ist

building this this week

@jeanna
the first jt pickup coils is ala mk way ?

i am asking because, if it is, then the red + and - does not really have a meanning since it output an ac signal.
