@abassign
how is your circuit going? You showed some battery charging voltages before. Are you still working on that?

Fausto.

@4Tesla

Any news for your parts. I'm really getting pissed off with these guys. No e-mail, nothing.

Since no descent ferrite in sight, I am starting to try different transformers. That's one of the reasons I asked btentzers' for the ohm values of his coils.

@plengo

Just to let you know, I took EMs circuit but put two toroids, my big one and the small one and put them both on the circuit in parallel. I then took my 9V battery that was dead days ago and that went back up to 3.456 volts, shorted it again, also added a large cap 41000mfd 25vdc, that was shorted out and that never goes up on its own, connected in parallel to the battery and then connected this to the circuit. It has been running now for two days with the LED still lit but very low and voltage at the cap is steady at 1.547 volts. Goes down a tad, then goes up again, down, up, etc.

I think this is the first thread in a long time that is dealing with two devices in one thread. Kind of crazy but hey, birds of a feather flock together.

@ Wattsup
Each of my three windings on the toroid measure 00.2 Ohms.  This is with the meter set at the lowest of 200 Ohms.

I hope that helps you! 

@ All
I am still messing with one wire wrapped over the toroid in different areas and its effect.  I also want to lessen the number of turns on my trigger by half and see what effect it has on my run time.

Holiday Cheers,

Bruce

EDIT:
I lessened my triggers winding from 10 turns to 5 turns.  The frequency of the blinking lights greatly increased and thus the time was decreased by almost half.

I increased the trigger windings from 10 turns to 13 turns.  The time was still less by 1/7th.  It would seem that for my toroid, the optimum wind for the trigger is indeed 10.

Thanks for the ohms. If I remember correctly, you are using the same wire AWG on all three of your coils and maybe that's why you have the same ohms. This is important to note. My coils range from .9 to .2, but none have all three equal.

Also, thanks for trying different trigger lengths as I had mentioned a few posts ago. Even though my LED on time is the pits, this enables me to quickly see the slightest difference in windings and I had noticed that more trigger worked better, but this just means more for that coil. This proves the relationship between the coil and LED on times, plus it now proves that there has to be an optimal trigger length. Now imagine if the optimal trigger turns is matched to the optimal coil turns.

That would mean keep the trigger turns and vary the coil turns and test. This would then answer the question from both sides. Unless of course by some freak chance you wound this the first time the right way for all coils also. In that case, you should give me some numbers to play the next lotto 6/49.

I am going to test with ready made transformers, but I need to find small ones that have one primary but two separate secondaries (four wires) and not with two secondaries via a center tap. (That's only three wires.)

Geez I can't wait to get my ferrites. Maybe Santa will take care of it.lol
