Don't thank me...thank STPRUE, he is the one that posted the links and found this device.  I believe this will take us all in another direction...which is good.  I love to learn but I have to learn by doing....even if it's wrong.  You can adjust the duty cycle in these things....something we would really have to work at with  the old JT circuit.  We can hit resonance easily I think.  I have a scope and have to re-learn how to use it. (not that I really knew in the first place)  This will be fun.

hey Stprue thanks for the head up and did you see that they also have the Ts1002 free board. With a few parts they have a schematic to make a self powered energy harvester with that one . so i asked for it and the 3001 . see what happens tomorrow i guess .. phone call ?.

Energy harvester will rectify a tiny current and store it in an ultra cap or super cap .runs on 1ua  stored from a small cap and i see this using clear leds as replacement for the pin cells input

Ok heres the Circuit . I have not tested it yet . and the symbols i had are not correct for the the toroid . there are 5 separate windings . When i built it originally this all fit inside that little three led stick up lights . they have three battery compartments in them . all the parts were small and i used a bead barrel as the core . I used #38 wire .I have two spools one #36 the other #38 .I will try both as well as #26 on a goldmine ring. If you just want to take my schematic and save it thats ok by me . 
Corrections might be needed as i don't have a circuit simulator anymore .If some one can run a tint cad file let me know .  I am waiting for an order to come in for some parts . I guess this can work on the goldmine  5/1$ toroid and maybe use any wire . parts list can be anything you got laying around . I know i used germanium diodes on all those and small pf disk caps and tiny electrolytic but any size might work . i know the primary coil is Litz and join two opposite ends.this is the main stage of a Jt except i combined the two Litz so they are wound the same way .11 turns.. there are  three separate secondary  . two are around 22 turns . one is wound clockwise the other counter clockwise . the last winding is 11 turns on top of the original primary litz .cannot remember if it was wound in the other direction or same . . Need to put it together .  .. thats about all for now. . As soon as i get some parts in i can try this out on several transistors i got laying around . The pots were 10k
Gadget Loop  test 1 Experiment . the goal is to light a light and feed the transistor just enough to keep it in oscillation without any loss in a battery . alkaline works good but nicad  don't. Nimh  is preference i use nimh Eveready . they are about 1.25 volts  .i can try  Dead batteries  around a half a volt for starters on this one and should detect an increase if it is working . .This is just an early release for  proto board only .

I got my shipment in today and...I am disappointed.  I wanted the entire board like shown in ST's video and the company's video but, I guess I plugged in the wrong part number because all I got was a very small piece of something I can not identify.  I already wrote to them and I will pursue this further.  I can't really complain too much as it is free, with free shipping and the mistake was probably mine.  I will keep you all posted.
