NickZ, Wilby and Gadget:

Thank you all.  I thought it was just me that could no longer log on the the Dr's site for the SEC-18.  I am still not ready to play with it just yet but I will save those links Wilby posted for future ref.

Nick, I think the term "practical" is the one in contention here.  To me, all of these are practical but, commercially and on a large scale, probably not. (Not yet anyway)  You are right about China.....those solar led lights...I bought 5 of them for under $2 US each.  I could not buy the rechargeable battery for that, much less the led, reflector and circuitry...and the photocell and solar cell.  What a deal!  I have rebuilt most of mine with much brighter leds and, they still stay on long into the night and are brighter.

We don't always have to agree here...that's cool.  A lot of this is to each his own if you know what I mean.  I, for example, still get excited looking at my first JT running an led from a single AA.....I know....but I really do, ha ha.

Nickz . ? there are schematics buried in the huge thread that i posted and don't even have a copy but in 2009 EVERYONE build a JT . We nailed down the turns and winding procedures  (jeanna)(Mark)(XEE) IST and many others  and had a standard for core (goldmine 5 for a dollar) and transistors 2n2222a or 2n3904 . We blew up leds because they were so bright off an aa battery . They are the most efficient light producing circuits in the world. I really don't see it from your point of view. I guess it takes a high light bill with no money to pay it to appreciate the light  I can say without a doubt nearly everyone here since 2008 has bright efficient lighting from a single cell . some even used two . Anyways to each his own and keep up the sharing . Actually it was the Trolls who drove most people away and some of the  Jt circuits was calculated by the finest professors and mathematicians to be over 101 % efficient. I don't think you found our work or theirs .
Anywho thanks for sharing and as i said before there is a lot of work left on a Jt to each their own and i respect that bro. . you have to look back from page 1 to about page 3000 somewhere in there are the most efficient diagrams and parts list .
And yes Solar is the way to go . I have a gridtie and 500 watts of panels outside and a 600watt wind generator charging 4 airplane batteries . Love it .i can make my digital utility meter go backwards .light bill now runs between 68 and 160 . used to be 300 and have seen a couple of 490$ bills before i put that system together .  You may have miss some of those small CiS cell projects but i went cube crazy with them using baseball plastic ball display cases . also how much light do you need . i use this one every day and night . 40 watt new designed 110 bulb lights one entire room enuff to read by 10 feet away from my ring powered by c ells for days and days  . weeks if i only use it from night till morning . here are few pic s. I cannot tell you how we would those things but this one uses a supoercap with 5 min light produces bright light all night . as the cap slowly drains another set of light in it take over due to a change in frequency and the flux off the torroid moves . So the toroid is wound with secondary s on different side  and catch that energy as things change in that circuit . One CIS CELL 4.5v .. and if can't get enuff light off your Jt's then you should try Darlington transistors . they amplify twice as much as a the 2n3904 or 2222a..

wish i had the time to go thru the intire thread and put it all in a doc form so a search could be done on a particular design . BUT this post is one in 10's of thousands started By Bill with a simple question about why  a resistor was or wasnt needed now there are several designs that dont need one at all .

first pic is new clear 40 watts for 7 expensive 110LEDS bulb .This is so bright is washed out the camera .  It light my 14 x 20 bedroom corner to corner .

the last three are one of my solar cube lights . the bright led is super bright and lights all night and then the next day and some time later the other two wide angle 200,000 mcds take over and light the rest of the time .

fun times . and getting back in it if i run across some schematics i think you might like i'll pass em your way .

BTW . kooler (robbie) lives a few miles from me .. He has got some amazing power off that lil aa . light thousands of leds brite bright .

Wilbyinebriated . I have a hard time spelling it correctly . Man you were the First one to show a CFL and camera circuit . That was My inspiration Man , Thanks for helping and you got some nice stuff you shared .

aww shucks... thanks gadget.


@nick... i had to hunt a bit for it too... i was glad to find it online so i didn't have to go looking through all my offline storage.

@bill... play with it when you find the time... and the NILS is fantastic when properly tuned.

dum spiro pario...

  We don't have to agree. Nor do I disagree.
But, I guess that the trolls must have missed me. So far... or got lost on there way.
  I have seen every video, read every post, and know of most all that has ever been done or said, or replicated with these devices, in this and other forums. I use Jtc, and Exciter circuits daily, and I have them on right now... so, no need to tell me what I don't know.
 
  I encourage you to demonstrate a device that is over 100 % efficient with it's input source. Or a self runner like you mentioned. I would love to see it. But, not dim, or blinking leds, that last "forever" A self runner is all the proof that we need, and, a real "practical" device would stimulate more interest to replicate and continue in this field.
  I am not arguing any point, just opinions, as I see it. I'm not trying to be right, just trying to learn, and improve the gadgets that I'm interested in, and working on.

  If we just wait a little longer we'll see that China will blow us away with their technology, and what they do with it.  They have been hard at it. All we'll have to do is buy their products, sometimes even with free shipping, for less than it would take to make them, or the time spent on it.  But, electronics is my hobby, and was my job previously, now I'm retired,   and retarded if not working on something.  Ha!
  I appreciate these interesting circuits as much as anyone, or I wouldn't spend untold months, and years at it. But, I would like to see much more become of them, and the prize would go to the self runner, or runner up.

  If you see Robbie, please say Hi for me, send him my greetings from Costa Rica, and tell him that I would love to see what he's been up to.
  Gadget: Thank you, I'm on your side...

   Willy:
   Thanks for finding the info on the 18x board.  That is very important stuff, for those of us interested in the field. It took years of hard work for the Doc to get it to that point, I can see and appreciate that now myself. No easy feat. As any progress on that device is hard to come by. He is a magician.  I can only imagine what's to come... even he said that China already had a "knock off" on some of his work.  They're impossible to compete with, as they work practically for free.
