Does this show that you can light 3 leds in series with only 1 AA when the current path is through your new coil?

Pretty cool.

Is that a series or parallel light circuit?

good stuff, Mark!

mK.. Jeanna and the others...

Yea... i don't see how a pulse is going to run a second JT.

However a Diode and Capacitor can create another 'battery" that allows JT 2 to do the charge Inductor thing on it's own terms.

                             JT1==== D + C ==== JT2 ==== JT2output

I will give it try later... I think this is what tysb3 is doing..

Yep when the circuit is connected the satellite coil pickup the current going to and back from the battery .

They are not in series but parallel but they share the cores , so they are inductively coupled via the core .

I got the inspiration of the experiments with 2 jt on one core , the second jt working without the connection to the battery .

But i use the NPN and PNP pair and the base from on works from the second one bemf , that way i think i can sync both circuit , if i had a scope i could help more there but i got idea instead ...

how its looks on diagram

with all my test so far on the regular jt the best combo is the gadgetmall trick with the cap on the unused leg of the pot..
gives you better light on the secondary with alot lower ma's draw..
