Joulethief SEC exciter and variants

super joule thief sec jan 5th video rep attempt...

Hello johnydavro and all involved here ... I went to the drug store and got a couple of disposable camera boards for the trigger transformers and the other misc. components and gave it a shot. my first attempt at the circuit..my problem is not knowing if i have the correct transformer or not...I used the tiny three lead unit off the camera board and it doesn't look like your transformer(10 mm toroid?) I would have posted some photos but the camera is hiding somewhere. the circuit did have a noticable buzz on an am radio so I think I'm close but no SEC effect yet...if you guys have any winding advice I can wind a coil and have several types of cores to work with thanks alot I will try to find the camera in the mean time...

the error of my ways...

this is my attemp to get the joule thief to produce a field....
my appologies I went back to you tube and paid closer attention to your video(s) and see where I was going wrong... the step by step SEC build explained alot. I have two trigger tranformers and one has a primary of .2 and the other has .7 ohms (the blue one is .2 and the yellow is .7) the transistor got hot on the .2 blue unit. Is this where you put the copper tube heat sink on as in dr stiffler's video? my av plug showed very weak signal
(had to touch the output with it) thanks again you guys are miles ahead of me...

Hi Area46241.I just measured my blue trigger coil and that is 0.4 ohms but yours should be ok and it is good to have two different values as when you get your circuit working,you can swap them and compare the output.
I am a bit confused which variant you are trying to make as you mention the super joulethief and torroids but i would start with the simple sec as that is as the name implies,simple and quick to get going and then you can see how the trigger coils you have work and then try the others or let us know which variant and we can help get you going.Jonny

Hello everyone, I just finished building my first SEC circuit. It’s just an mpsa06, a trigger coil, a 3.7 lithium battery, and some metal bowls. I am looking to transmit power about 1 to 2 feet across a table to light about 20 LEDs, but currently I can only light 1 led when it touches bowl.
I see that everyone else uses coils of wires as a replacement for the bowls. Any recommendations to making these coils like number of turns, size?
There are many circuits on this thread, which one is the best for transmitting power?

Brad28304 here is a link to Dr Stiffler's Wireless or One-Wire Energy Transmission Construction Guide.
It tells the specs of the towers Lidmotor and I are using.
Wireless or One-Wire Energy Transmission Construction Guide

You should also use more voltage like around 12v.
To adjust current intake move the towers closer or further apart from each other.

Here is also a link to some of his other papers.

simple SEC ran for an hour today...first time

I successfully got my simple SEC up and running with the blue trigger transformer and a 2n2903 npn and one other transister some no number generic..it seems that both of them have failed or I can no longer get resonance after changing the leads around a bit. I used alluminum cans for the trays and had two different av plugs lit up one of them was a red led av and was dim the other was a five led flashlight lens out of a cheap wind up radio that bit the dust which was very bright but it only lit four of the leds. That made me wonder if the field only likes even numbers or maybe it just needed more strength. I tried a 3055 npn metal case and had no luck with it. I filled one of the cans with water and that seemed to help by adding mass to the can connected to the base. Has anyone here ever used an av plug on a cb radio antenna? I'm going to try it when I get time...maybe somebody can go outside and key the mic and see if it works...thanks alot johnnydavro for the technical help

I read the specs to the towers. How exact does it need to be, in order to work? What happens if there are more or less turns?

If you want transfer power from one tower to the other tower wireless.
The two towers should be exactly the same.

Here is another circuit that acts as an SEC Exiter.
It's running off a AA battery using around 9.5 mA.
It needs to be tuned better it's just crudely assembled on a breadboard.

The L2 coil is wraped around the L1 coil.

Here is the video.

And here is the circuit.

Simple SEC round three

I found a transistor! The mje3055t and the kodak disposable camera trigger transformer seem to make a good match. the trigger tranformer primary is .7 ohms and the secondary is 59 ohms. powered with a 9 volt battery the one ohm resistor in series with the positive yielded .109 to .450 volts with the higher during startup. I used an alluminum baking pan (connected to the base) on top of the kitchen sink and an alluminum drink can(emiter). One thing i noticed was that it works well when the can is pointing its bottom concave side towards the tray/pan. by touching the collector to the base with one hand was my best method of starting the resonance . The sink and fixtures were alive with energy. Another thing happened during the experimenting that I thought might be of interest...I was resting on my elbow and my arm had fallen asleep and right at the point of resonance in the same instant the av plug lit up and the feeling of numbness disappeared...anyone else noticed this? Jonny you're a great teacher by the way

Nice circuit...

after my last post I saw yours slayer I think thats where I'm headed next.
how many turns and why is the mpsa06 the transistor of choice in these exciter circuits?

It will also work with other transistors the 2n2222 works great also.
If been using the mpsa06 for a lot of things.That was the one Dr Stiffler recommended for his exiter.
And I bought a 100 of them for around $6 off ebay.

The L2 coil is 16 turns and L1 is around 300 turns.
That was a coil I just had sitting around and just wraped the L2 coil around it.
I'll have to try differant coils and see what works better.

Like I said it's not tuned that great yet.But it's a start.

DC motor with simple SEC

Hello,
Thanks to everyone for showing their experiments on this public forum to educate others.

Does anyone succeeded running a DC motor from the simple SEC design ?

I know it is possible with the SEC 15-3, I have done it 20 months ago, and I suppose it's possible with the simple SEC But I am not in a position to try it.

Now that it seems possible to get more output from coherence, using towers or water, I was wondering if we could run larger DC motor ?!?

Thanks to the experimenters for sharing their findings

@Slayer.Great new circuit Interesting how you have done the coils and L1 of the base and all on low voltage.Nice work.
@area46241.Hi.Sounds like you have cracked it:thumbsup.Here are a few other things you can try.I think your current draw is a bit high so try using a smaller tray on the base and larger on the outputas the more energy the base recieves,the harder it drives the transistor and just heats it up and try it off the sink as if the sink is earthed,it will send your amp draw crazy.I have not managed to draw 450mA ever and prefer to run at 40-60mA and the 9v battery is not my first choice to power the simple sec or any other sec,they are just convienient and i find AA batteries linked by a small magnets very useful for experimenting with different voltages as you will be suprised at how bright the leds can get at low voltage but you will have to use a bc182 or 2n2222 transistor,mpsa06 won't work and twist the base and the output croc leads together or better still,twist the output and base wire's together on your breadboard to run on 1.5v.
@stephenafreter.Hi. Did you make a vid of the sec and dc motor?I know lidmotor ran his One mag no bearing bedini wireless of a sec and i did one off a plasma globe but i have not tried a dc motor.I am pretty sure it would work of a charged cap though.What were the specs of the motor you used?Regards jonny

@Jonny, Thanks.

@All, I tried some other coils last night.I wanted to shrink it down with smaller coils but it didn't work at all.
The coils right now are L2 @ 4u 16 turns, L1 @ 530u around 300 turns.

It seems to like a bigger L1 coil so today I'll try making a bigger one yet.
