Joule Thief

So i connected the two pickups in series, the END of the first pick-up and the START
of the second pick-up (the start being the end i wound up and down)

yes, it is confusing. I think it is the best reason to cut them. Then just do as the man says.

a single pick-up gave me 134v
pick-ups in series gave me 141v

Right. My experience also. It would seem that one got swallowed up by the other until you...

.  i got 247v
this fills a cap fairly fast to 247v then slowly climb's to 270v

I am beginning to think that the meters are missing the spikes but the caps are not.

Thank you for sharing your results. It confirms much of what I am getting too.

thank you,

The second picture looks good , they look like comun mode choke , there usually the right stuff some are better , but usually all good.

Yes, I made the MK1 and hybrid using this in january. I liked it (and the charcoal from allelectronics) so well I bought more (of both)

How big are they , i hope we could find 1 inch like those .They are high flux usually.

Just over 3/4 inch OD and just under 1/2 inch ID (over 2 cm OD and just over 1 cm ID) The cement color is a paint of sorts. It peeled off with the black glue when I pulled off the wires, once.

Most of the ones I have tried from the goldmine are here:

But, remember, I have NOT been able to achieve the results you are getting with your choke. I get under 40volts from each side of my MK1 and this is the one that seems to be able to deliver 110 volts to a cap when fully rectified.

The filter is pictured 4th down on the page. You can also see the bad blue, and the high permeability disappointment, scrolling down is the 5 pack of medium.

These mediums are not bad. A lot of us have these and this fact makes it useful for comparisons. If one of us hits a good number of turns etc, the rest of us can try it out.

Goldmine's minimum is $10.00 and the shipping is $7.00 so you might as well get some extras to try out.

@Bill,
I am remembering that the earth battery arrangement that lit a red led, employed a supercap IN PARALLEL arrangement with the led. I think this is where your answer will come for filling and discharging simultaneously.
I really don't know if a change in cap or adding a resistor also would enable you to get your goal, but something tells me you were on it a long while ago.

Check this out! I know you will like it ! they trying to find justification.

Yes they are good but not that good , 40 volts dc is not bad for those, you could get more with smaller gauge more turns, I just got some toroid that are about the same got 45 volts on a 24 turn pickup coil , made from 26 gauge mag wire , its not getting the good numbers the green one gets , probably bigger flux , but i did not have time to tune the charcoal one yet so i won't comment yet , but testing the jt turns to make sure to get the best output, then going to a smaller mag wire
will get you closer. Also i did mention about the transistor 2n2222 work even when the collector and emitter are reversed
this you need to test to see , one side is better , the 2n2222 is also called a negistor .

Mark:

I am glad to hear that as I have a bunch of the 2N222's.
