Joule Ringer!

Conrad,

Don't restrict yourself with that Torroid.  36:9 (4:1 ratio) turns isn't what LaserSaber suggested.  Before giving up on that Torroid, be bold and try 90:9, or 100:10 turns.  Yes, that will be a lot of wire, but give it a try.  That Torroid you have can handle high frequency.  And if it is a gapped Torroid it will be even better.  The black ones wont work.

You might try the circuit with just the transistor and delete the other components for now.  My guess is with another try you will be pleased.  Don't over think it, it is so easy, just a simple 10:1 ratio on an aircore, ferrite core, torroid and the one transistor.  The heavy insulated wire is important.

With the turns ratio 10:1 you wont light CFL bulbs and especially if they are left unmodified.  The 10:1 ratio works well for LED bulbs.

Try it one more time!

@Lynxsteam:

Thank you for the reply. Trying one more time is no problem.

My reasoning:

The toroid (Ferrite material 3E27) can handle the high frequency, but some unmodified LED-lamps (which I bought) can not handle high frequency and the unmodified CFLs can not handle it either.

The right Ferrite material is 3C90 or 3C85, and its high inductance will cause a low frequency (around 1 KHz, up to 3 KHz).

Bigger laminated iron core transformers will also cause a low frequency (because of their high inductance).

But I might be wrong, trial and error is better than "over thinking".

Greetings, Conrad

I wanted to report back on my experiments.

The aircore LJL with heavy insulated secondary made no difference.  It was actually a bit worse because I couldn't get as many turns in the same space.  The bulb is very bright but amp draw is slightly higher. 
The aircore coil with Tesla Parallel windings for the secondary was even worse.  Very high amp draw, very bright.
I rewound my second Super Joule Ringer e-core with the right bell wire and proper turns.  Very bright bulb and 400 ma.  This is slightly higher amp draw than my first SJR2.0 but brightness is superb.
Is this circuit also back charging the source battery between pulses with DC component?  Are we reusing current through the circuit?  Is there a reverberating bounce of magnetic field?  Something isn't right that we are seeing this many watts of work with so little input.

Below is an updated chart showing the 2nd Super Joule Ringer 2.0 with 22:220 turns of telephone wire 24 awg.  The bulb brightness is very good up to three bulbs.  The 4th bulb causes the brightness to drop but so does the amp draw.  I didn't chart the newer LJL aircores, because without lumens/lux it doesn't mean much.  What i find interesting is that with the aircore the amp draw increases with each bulb, whereas with the SJR 2.0 the amp draw rises and plateaus.

Wanted to express my appreciation for all this work, Lynxsteam.   The graph is particularly instructive.

Well done!!

Now if I may request detail:

Below is an updated chart showing the 2nd Super Joule Ringer 2.0 with 22:220 turns of telephone wire 24 awg.

Single or double -- "telephone" wire?  solid or stranded?  Would you recommend 24 awg, rather than a thicker wire?  for both secondary and primary?Did you use the cores recommended by Lasersaber, from Nebraska I think, or some other E-core?

I am using an EA-77-625 Ferrite E-Core out of a power supply.  I had two of these and they are rated for 200 watts.  The wire I am using for the primary and the secondary is 24 gauge solid copper telephone wire scavenged from some 6 pair telephone cable.  Bell wire is a little too thick and stiff for these smaller E-Cores.

The dimensions on the E-Core are 1-11/16" x .625"  The Bobbin will accept about 259 turns total of insulated 24 awg wire if you are really careful winding.  I used 22 turns on the primary, 220 on the secondary and had a little room to spare.

On this second unit I used the pair of primary wires leaving one of the two disconnected. 

These units will light all 6 LED bulbs nicely with no noise and no heat. 3-4 Bulbs brightly, 6 bulbs at 60%.  One transistor is all you need.  There is no adjustment necessary from 1 bulb to 6.
