Joule Thief

[TheSchuss]

Good to see you.

Check out Dr. Jones's topic on his possible 8x OU JT.  XEE2 posted a circuit there that lights an led but draws less than 5 micro watts!  Very little energy going in.  42 mA's is very high, I don't think my Fuji's putting out 400-500 volts draw that much.  Try substituting a VR of 5k or 10k value and then you can tune for lowest possible draw vs having it light up.  It helps to find the sweet spot.  Plus, as the battery drains, you can retweak it as it drifts off resonance.

None of the circuits I have built draw anything near as low as Dr. Jones's or XEE2's.  That is a whole new ball game over there.  I hope to be able to replicate some of those circuits soon.

Bill,
Am a brand new member and learning to find my way around this forum and finding the various topics.  Could you post a link to Dr. Jones' topic you mentioned, I'd really like to check it out.  Thanks for the help.

Yep, some of us are very new; to this forum that is, like myself.  I joined on Saturday 8/6, started reading the comments on page 1 of this thread; dated 11/20/2008 over the weekend and managed to make it up to page 25, dated 11/23/2008, about 625 post in all, back when you all were still messing with the Fuji Camera circuit.

welcome to the forum.

BTW, did anyone ever figure out how to make that circuit work?  Mine ran at 306 volts, 8 mA, it did light a 15W fluoro tube at about 1/5th brightness.  Using Ohm's law, I figure if the amperage could be increased to about 50mA at 305 volts the fluoro tube would light just fine.  Any suggestions?  Do you know what Ohm's law is, or even how to apply it?

btw, about the circuit you are asking if anybody got to work. lots of people got it to work, yourself included. because that's what 'working' is for that circuit. simply because it doesn't light the tube to full brightness doesn't mean it isn't working. the circuit cannot light the tube to full brightness... nor was it ever meant to. you keep on learning about ohm and such and you will eventually learn this too. and speaking of ohm's law, how do you plan on increasing the amperage? knowing how it works and all...

Excuse me for saying so but in your posts in pages 1-25 you came across more like a blind man with a dim light than someone with a bright idea and no one Criticized you!  I'm not sayin', I'm just sayin'.

you are the one coming across as a dim light here schuss... even with you knowing how ohm's law works and all.

I find you, and your buddy he'sinebriated(again) comment's especially Offensive because you're both supposed to be 5 Star "He-row" members.  In that capacity I would think you would be willing to help and give direction not just throw out snide remarks about newbie posts or questions.

Fact of the matter is, you couldn't read over 25,000 posts on this board in a month to get caught up anymore than anyone else could so such criticism should be beneath you.

Please feel free to forward this to he'sanebriated(again), cause honestly, I just don't feel like sending it twice.

which specific comment of mine did you think was 'snide' and/or offensive? the one about it being done before? LOL, how would you suggest i tell him it had been done before?

you don't know me son... and the fact of the matter is, i could read a couple hundred pages of this (or any other thread) in an evening... and if i had a whole weekend, i could read this entire thread more than once. just because you are slow, don't put that on everyone else.

it's wilby... as in 'will be'... that's future tense, not past... not present...
now if you will excuse me, i have to add someone (you) to my ignore list.



here's a link to dr. jones' topic: http://www.overunity.com/index.php?topic=10773
there is only 50 pages (700+ posts) so it should only take you a little more than a weekend to get caught up there versus the 70+ days (at your current reading/comprehension rate/level) it is going to take you to get caught up here...

You may want to look at Joule thief 101 thread >  http://www.overunity.com/index.php?topic=8341.0

It was started to help new comers get basics without reading all the posts.

Hi everyone !

I wanted to show this before i forget to share ...

Its been sitting there for quite some time so there you go .

This is my version of the Ns coil ,with increased surface contact .

Also the secondary coil can be wound directly to the core . It is at the same time a pancake coil 14 inches gave 13 mili amp , i wounder what 14 foot would do .

awesome..
one of the cooler things i seen in along time..
you do interesting research..
i have also wonder how a battery would perform if wound like a cap..
please keep going. is that really 13 ma's and not 130 ua's..
if so.. very well done..
