Joule Ringer!

[Lynxsteam]

Somewhere a couple pages back I posted specs on the E-Core I have been using.  I used 16 turns primary, 160 turns secondary - telephone wire 24 awg.  I used the single 2N3055 transistor.  Primary wound solid across spool and one wound with two primaries, one unused.  Primary wound first.  Diodes anywhere in the circuit are not so good.  Resistors anywhere just burn amps.  Caps have little effect.  # of turns on either primary/secondary don't matter for oscillation.  HV can be connected or not.

I would love to hear how you got 71 L/W.

Tank circuit.  Think about that.  Why is it called a tank?  Do we want a teacup or a swimming pool?

Thanks for showing interest --  going from 64 Lm/W with the air core PLUS two 20cm Ferrite cores laid into it, 71 Lm/W was achieved by simply moving down the taps, from primary winding 37 (64 Lm/W) to 31 (71Lm/W).  Going further, the efficacy dropped off -- at winding 25, 61 Lm/W.

OK -- I have some wire and I have the e-core recommended by Lasersaber.  I will use heavier wire for the 16 turns, lighter wire for the secondary, NO caps or resistors -- see if I can get it to fly.

Tank circuit?  makes me think of an LC circuit.  Without caps, the only C is in the turns... could still be a tank circuit I think -- Is this what you are saying?

So today I wound the Lasersaber -recommended E-core, and fired her up!  worked great, after a little fiddling. 
Thanks for input -- especially Lasersaber, Lidmotor and Lynxsteam.  (The three L's?    )

If you see the voice out-of-sync with the picture, let me know, would you?  I'm seeing that problem.

Here's the description with it:

I did a replication of Lasersaber's 2.0 super-Joule-ringer, described here:
http://laserhacker.com/SuperJouleRinger2.html
First runs at 10V from the power supply, at about 0.08A.  I measured the Lux output from a 1.5W LED bulb, shown in the vid, in my calibrated light-box:   440 Lux, so 35 Lumens.
The input power is 10V * 0.08A = 0.8W (from the power supply readings). 
So we have for Lasersaber's 2.0 operating at 10V input, 35Lm/0.8W =  about 44 Lm/W.

This is less than I had with Lynxsteam's air-core system shown in background in the vid. BUT, in next vid at 17 Volts, the E-core system gets up to 74 Lm/W, which is better than I ever got with the air-core system (even adding Ferrite rods into the air-core system).

Since this is my first winding of the Lasersaber E-core, I'm quite sure even higher Lm/W yields can be achieved. 

I highly recommend use of the straightforward light-box (described at energeticforum.com and overunity.com) to get quantitative Lumens/Watt readings -- much more reliable than the naked eye!

   Thanks Steven, looking good. Lets keep at it, you might beat all expectations.
   The super Joule Ringer  2.0 video is currently unavailable for viewing. 
Any one know what's going on, or it is just me?

  OK, I've done a vid on a few more tests:

Nothing spectacular, but lots of fun.
From my description of the vid:

More experiments on my replication of Lasersaber's super-Joule-ringer 2.0 (described at Laserhacker.com).   Here I add one 82 pF cap across the LED lamp (a test recommended by Lynxsteam-- thanks!).  I also show the effect of varying the voltage on the current draw and on the light output.  At 17V input, the system reaches about 70-72 Lumens/Watt.  One hand on the voltage control, the other holding the video camera... Happy experimenting!
