Joule Thief

It  looks like we think alot alike




I have a couple  solonoid  coils that I made  quite a while  back .........before  the  NS  earth  battery  thread .
I have one  coil with  4 pairs  of wire and another one with 6 pairs .
My plan  was to   drive   one pair  with  a signal .
another pair or 2 was to be resonate circuits .
One  pair would be used as output .
My theory is ....... you can;t  tap all of the energy ........   you have to tap it indirectly  and leave enough   to let it keep ringing .

I never  got it working .
I  still think it is possible  .........this was one of my first  tries at buildinig

Thanks Gary, yes there are a few of us at times seem to be comeing up with similar ideas at the same time.

Like I mentioned just before, I will have to read up on all the posts today, and there are a lot, I feel sorry for the next crew who come along lol.

Stprue is gonna know what Jeanna went threw to catch up, I know what thats like.

@ Jim:

Wow!  I just got a chance to download your videos.  That 1 watt luxeon was well lit indeed!  I really enjoyed hearing the excitement in your voice while filming, I am happy for you.  I am confident we can get your EB output up even more.  I never used that download section before, it appears to work very well.

Also, great idea on how to wind your super JT coils with the loops, I would have never thought of that.  Nice going.

@ Jeanna:

I also saw your videos as well.  Great scope shots!  You should have said hello while filming though.  I am glad you and Jim are posting these scope pictures and videos for us.

Mk:  I like your new design.  I am so far behind on these new designs you and everyone are making.  I can't keep up.

@Pirate,
Thanks Bill, I really was excited, this was only the second time I have lit a LED off my EB and it was totally unexpected.

The 1st time saw a LED work off my EB, was about a year ago.
I hooked up the 1st JT I made to it, the LED flashed just 3 times very weakly, and it never lit from the EB again.

This second time I had the 1 Watter Star LED in it's place, now the minimum voltage to light these things is 2.30volts, max is about 4.37volts
I had a 330ohm resistor on one leg of the LED, just in case, and it lit up WOW was I surprised.

1 Luxon Star LED is rated at 825,000 mcd, (Millicandela or thousandths of a Candellela)

@ Jeanna,
I managed to post my videos to the MENU, but how do I get a link back to the JT page, say to here. I tried different ways but couldn't do this, help.

I ask you as I see you have succeeded with doing this with yours.

Thankyou

opps, looks like I did this back to front, sorry all.

Thank you gadget,
That is a very thorough answer. And you did all this on an EB?

I just am asking if it worked on the EB. I can get all kinds of things to work on really dead batteries, but not on my EB. I believe it can be done, I just have not been able to actually do it.

Jeanna:

I am sure with a little tweaking you can light stuff from your EB.  What supercap did you try to use and how did you have it hooked up?  I believe you said you were getting around .8 vdc and this should be high enough to run one of your JT circuits.  If you want, PM me and we can discuss this and I will try to help you.  Just ask Jim, there is nothing like seeing a light illuminated from the earth.  I am sure you will love it when it happens. (and it will)

@all

I have completed my very first 4 Parallel wound output Joule Thief.

          IT WORKS yippee           

Each output puts out 86 actual measured volts (X 4 = 272 theoretical volts)
Each coil is 86 turns wound on the toroid.

I have coupled together outputs 1, 2, and 3 through separate Bridge Rectifiers, which the Negs outputs are soldered together to the "star" NS terminal.

It appears I can recharge the 1.2v NiMH battery.

The 4th  output can also drive a High Brightness LED or my 1 Watt Luxeon Star LED using a Joule Thief.

If this unsusessful I will have to do away with the "star " connection and make seperate outputs from the toroid.
