Joulethief SEC exciter and variants

[marxist]

first time lucky


Thanks for the schematic.
Like a charm, slayer007, like a charm ...

Had such big reservations about trying this. Had such great fear it might not work and I could never do such a thing.

Sorry for being a bit sloppy about the technical details in my replication
;-)
used what I had at hand:
- inner coil to be shifted, 200 turns of diam 0.31 mm (28 AWG) magnet wire
- outer coil wound in opposite sense ca. 12 turns of diam 0.6 mm (22 AWG) magnet wire
- used a 4.7 k resistor after the transistor got really hot with the 1k but honestly have no idea if that is the right solution.

No tricky tuning no nothing. Just pug 'n play.

No time for proper testing, yet, but it is the first time I can hold a LED at its plastic head and it will light full brightness, wirelessly. With my own "vortex trafo exciter" I always have to touch the wires of the AV-plugs or ground the AV-plugs.

Thanks also to the doc for starting this whole affair and to all the collaborators in the old and new threads.

Great job Marxist

You can adjust it by moving the coil up and down the big inductor.

Great job and thanks for sharing your results.

EDIT Another thing I noticed is with my setup it works best with around 5.5 volts.
Changing the voltage also affects how the coil will resinate.
And it will have to be retuned.
I was getting way better results with 5.5v than 12v.
Need to find a coil resinance calculator online.

Slayer exciter---Replication

@Slayer and All
I replicated your two coil (transformer style) exciter late last night and got amazing results. Like Marxist I used what I had on hand so the setup was also a little different. My coil arrangement is like his and like him I raised the base resistance value--all the way to 1 meg. On mine, once the thing started I could even pull the resistor. The amp draw was WAY up there around 100 to 200mA but the output was like a SEC15-3. I ran it on 5.5 volts. The little 2n2222 survived and I will do more testing today.
Thanks Slayer for presenting this. It sure makes me wonder (even more) what the heck is going on here??????

Lidmotor thanks for posting your results.

The amp draw is still a little high.But with a better coil ratio it should be able to be lowered.
Mine is drawing close to 150mA but I was lighting the 6w fl 60 leds and a half lit 20w fl.
All at the same time using the cell phone charger around 5.7 volts.

Jumpin' Jack Flash

While exploring my new two coil (transformer style) exciter, I think I found a strange jumping effect in the brightness of the wireless LED probe which is also visible as a voltage rise on the oscilloscope and registered as a magnetic signal by a non-connected analog volt meter.
It happens within a fraction of a millimeter when adjusting the position of the coils within each other.
My replication oscillates over a very large range of coil positions, but this jump happens at a very distinct point.
I tried to capture it on video:

Hi Lidmotor,
can you give your reason for choosing a bigger resistor than in slayer's original schematic?
Yes, I also did that, but more or less just 'monkey style' (a plengo quote), as the transistor got real hot, initially. Was this also your reason to chose a higher value resistor?

[slayer007]

Here is another short video just trying differant coil setups.
In the video I have another coil inside the bigger coil thats also going to the transistors base.
I'm also using two transistors in parallel an 2n2222 and a MPSA06.
I also shrunk the L2 coil down a little so its more focused on the L1 coil.
At the begining of the video it's only using one AA battery then I add one more for two AA batteries.
It can also be more adjusted by moving the second L1 coil in and out of the big one.

Something else to try is a 10 k pot instead of the 1 k resistor for finer tuning.

Thank you Xee2

I also found this one.
RF Inductance Calculator - HAMwaves.com

I was think more of something I could put the inductanceof L2 in and the Mhz I wanted and it would calculate L1 for me.

When using a lower voltage like 1.5 to 3 volts this dosent use to much current.
It's kinda like a joule Thief circuit with the trigger coil connected throught inductance.

maximizing resonator voltage

There are an infinite number of combinations of capacitors and inductors that will resonate at the same frequency. For this application, I think the best choice is a combination that produces the highest voltage. This happens when the inductance is very large and the capacitance is very small. How large the voltage can get is limited by the reistance (losses) in the capacitor and inductor. Adding a coil to the resonating coil will steal energy from it (add loss) and thus reduce resonant voltage. Thus to keep the output voltage high, the feed back coil should coupled to the resonant coil as weakly as possible (keep number of turns small).

Note, this is all theory and what really counts are the experimental results. But, this is how I would go abouy picking what to try.

Slayer's Exciter ---my replication

@All
Here is a video of my version of Slayer's new exciter circuit. Marxist--notice that the 1 meg resistor is not even connected to the transistor base. The reason that I raised the resistor value in the first place was just like what you said---too much heat. Dr. Stiffler told us that once these exciters are tuned up right, the base resistor can be pulled and the circuit will still run. This one does that magic trick also.

Great video lidmotor thanks for posing it
I also liked how you used the Dr Stiffler towers with it.

Great experiments everybody
I really like the look of your new circuit slayer as i like circuits which can be adjusted for example adding coil turns etc as it means that there is always a performance improovement possible as anyone who has experimented with joulethief secondary coils will confirm.
I notice Loneoarsman has left a comment on utube reporting 1450v with this circuit and i presume that was his first attempt so some great possibilities here.
Nice replications Marxist and Lidmotor and thanks for making vids as it shows how good and easy this circuit is to make and may bring other experimenters into this field
@area46241.I can't say that i have noticed any side effects from the SEC field but that is not to say there arn't any as people are sensitive to different things.
I have had what i would call arc eye or welders flash from looking at the leds when at full brightness and mine are only 8000mcd but blinding.I now know this is a definate no no and now have sunglasses handy and i am being serious.jonny

slayer's tunable coils...impressive

thankyou jonny for the reply on the SEC. I have decided that a mild case of germs did me in...I have been pondering if the kitchen sink was excited enough to stimulate the germs to flight in the air from the drain possibly...another experiment for the medical folks
Donald L Smith on youtube for me was quite sensational and his tunable resonance coils as he described could pull in energy from "what was there"
The radio shack dictionary describes the circuits as being acceptors and in the old 1975 book even acknowleges the increase in energy in the resonance section. It looks like slayer and lidmotor have it. I'm ready to re-engage the exciter circuit. Now if Don Smith said he could generate killowatts with his suitcase shouldn't it be possible to generate something of magnitude with these table top units? With all these great circuits it seems possible to create a system to get off the grid...has anyone stored the energy and brought it back to 50/60 hertz like he did? the studies continue...God bless

Avramenko Pic may come in handy, attached....

Slayer Exciter with large coil

@All
I had a large coil (2 ft. long) on hand so I tried that today on the new circuit and it worked great. I put a sliding tube on it for the second small coil and that made a very tuneable coil like what Marxist showed in his last video. It was great fun lighting up all sorts of things. Here is the video of it--
