Joule Thief

[altrez]

Thank you theNOP
This is verification that what is coming off my secondaries is really ac.

Also, I didn't realize that it was proof of it, so... thanks,

@Altrez,
I bet there is a diode effect happening with the bank of leds.
If you have enough voltage, perhaps you could run another neon off the other pickup.

that would be very cool and worth finding if it will work.

(This is another reason that the 2 tier joule thief was doing something special. Every light there was a diode a led.)

It will not run a neon from the other pickup coil at the same time. Only one at a time? Can you not run more then one pickup coin at a time?

Thanks!

One at a time as in blinking?
Yes, you you can.

edit: I added this later but it belongs here:
One day I tried it when I was doing the 2 tier to see how far I could push it. I made an extra pickup for the basic one and used it from that having nothing to do with the 2 tier, except it was on at the same time as the 2 tier and was using the same battery and transistor. It lit as many as I had on hand, around 4 or 5 yellow lights  in series, too.

But there may be other factors we/I don't know about.

I remember someone saying that the neon will siphon off the extra voltage so it cannot go higher than a certain level. This is part of the reason they are used in the camera flash circuits. they flash themselves when the circuit is charged enough siphoning off the extra.

So, if your neon is siphoning off the overvoltage beyond some level there may not be enough for your bank of leds.

Does that make sense?

What happens if you use 2 banks of leds?
(ans. you have to go to the store for more fight?)

if voltage source is AC, then no DC voltage can be measured.

you are welcome.

xee2 simplified it, i explained it a bit more.
but by all means, it is far from being the whole thing about caps.

ex: else then there use in RLC and frequencies filters circuits,
a cap can be used to let AC through and stop DC or let DC through and stop AC by simply being connected in series or in parallel.
(across mean parallel, from one lead to somewhere else mean series.)

it can also be used as a current limiting device if you want.

The transistor is no longer getting hot However I am now working with more then one pickup coil and I have discovered that I can not run two pickup coils at the same time. For example if I Hook up the big pickup coil to a neon it powers it right up. As soon as I add my led bank to the second pickup coil the neon goes out and the LEDs light right up and visa versa if I plug the neon in after the leds they go out but the neon comes on?.

Can you not have 2 or 3 pickup coils all running at the same time? Or will only one work?

Thanks!

Altrez i have noticed the same effect BUT i Solved that Mystery . For me at Least. With A Variable resistor and a capacitor i i can have two secondaries with lights on each . By adjusting the Bias thus changing the frequency i can make one  or two lit . . I noticed the resistance is high above 100k to light the second secondary . It might work for you . . My real Advantage is the resistor wheel that electricme(Jim)  gave me. It is Great Determining the Value of a given Circuit for the best effects /ie.  5 ohms all the way up to 1 meg resistors and this baby Steps each resistor . from there its another Vr and cap to fine tune a selected resistance for a particular core and winding .I think the toroid see's the field like little rings around the toroids winding and as i adjust  the resistance and frequency these little rings of energy move and oscillate in a wired magnetic pattern  and either get thicker or multiply thus filling the dead zone with another secondary one it with those little energy oscillating magnetic energy rings . I can't explain it any other way and the y i did was probable wrong but  the outcome looks like that . It don't make seance to me why one would light before the other light unless something like this is happening . cause you can load the secondary with many lights but the second secondary only has one light on it and dont light  so its not power or current . Its got to be a moving field under  the dead area of that toroid with that second secondary     i think 

I got a friend sending the Sec parts . I can't wait to power it from a jt AA power unit!

Hey Gadget I just noticed the same thing with a 10k pot. If I adjust the pot just right I can light everything just fine and charge a battery? Its really odd! I can also light a neon and my led bank now at the same time if I adjust the pot just right?

@jeanna

I got it to work with 3 led banks plus a second battery that's being charged at the same time! The lights are really weak now and the main battery is down to .317v under load.

I think the FEQ has something major to play here I am just not sure what? I wonder if I hooked a second JT to the battery that is being charged and then ran its secondary coils into another bank of leds would it work?

And if so would it run for the time of 1 battery or two? Or could you keep flopping the battery's around for the time < total power of two charged batters or would it run longer?

Thank you!!!!
