Joule Ringer!

@Gadgetmall,
                      Lasersaber's Super JT 3 has 200 turns of 28 gauge magnet wire for the single wrap primary, wound directly over the ferrite rod, covered by 20 turns of 14 gauge household wire wound in the same direction.

Jouleseeker are you saying you could not get the same results with version three with the ferrite rod? If not why?

I didn't say that, please note what I said:

I then ran with 6 LED bulbs in my light-box, as I had done with the 2.0.  I found that the light output was about the same for the two versions (109 Lm/W for the 3.0 versus 112 Lm/W for the older 2.0 -- at 12.8V input).

So, about the same results.  Both my version 2 and version 3 use three ferrite-rods inserted axially in the air-core xformer seen in the video.  I discussed the version 2 with ferrite rods months ago; it was an idea back then to insert one, two and then three ferrite rods into the air core xformer of the joule-ringer 2.0.  See for example this vid I posted back in June:

What surprises me is the large amount of electrolysis occurring after about 15 seconds of running, as shown in the video.  Still puzzling over that.  The waveform from my version 3 output as seen on my oscilloscope is attached.

What happens to that wave form if you put a smoothing cap in there? Will it clean that signal up and make it less dirty?

Ahh thank you . that explains it .  BTW that ebay seller is getting greedy ans the are over 31 dollars now . you can save a heck of a lot of money buying it from his site directly @ http://www.rgb52.com/8-by-5-8-625-ferrite-rod-good-for-hf-balun-011.htm   they are 16 dollars there today


Yes Jouleseeker i know you didn't exactly that . I can do the same thing with one cell. I was wondering after your replication did you get the results as Ls did. thats all .  .

   JouleSeeker:
   Thanks for the explanation. It looks like your circuit is working well whether the  lamp is connected to the transistor control, or the emitter.  So, the bigger ferrite rod does make a difference, as compared to the air core coils without the ferrite.

   I made a smaller version of the 3.0.  I don't have a big ferrite rod, but I do have a 3 inch one that came out of a older am/fm radio.  So, I used it, and wound a 20 turn primary, and about 200 turn secondary, directly over this ferrite rod.  I can't find the 2n3055 here at the Shack, so I used what I had on hand, a TIP 31, which is actually a TJE 3055.  Anyways, it did not work, at all. So, I tried the small transistors that I use on my Exciters, and did get it to work lighting any Cfl, even the 65 watt ones, 25watt, 15watt, etz...  BUT, not brightly, and not as bright as the Exciters will output wirelessly using the same 6 to 10v input.
  Although this circuit will light better on 12v, but the transistors get hot.
  So, I'm still working on it, in the meantime, here's a couple of pictures. The first pic is the same coil running as an Exciter.
  When I get this further along I'll make a short video, as It's pretty impressive to see this small a coil lighting bigger 65watt Cfls.
