Joulethief SEC exciter and variants

@ slayer007

This is an untested suggestion that should allow easier control of feedback.

EDIT: I tried this and it did not work well.

[slayer007]

Thanks Xee2 I also tried something very close to what your showing.
My results were not that impressive eather.

In this video I just wanted to show the range the 20w FL will stay lit before going out totally.(It was around 12")
I also have a second tower 15" away from the main tower.
The L2 coil on the main coil is adjusted for the strongest output on the second receiver tower.
This test was ran off the cell phone charger that uses one AA battery 1.5v and puts out around 5.5v.

Here is the video.

@ slayer007

Great video. It is really amazing that you can do that from one 1.5 volt AA battery.

@ Hi Slayer:
Great last video, I think you have a very powerful circuit !
I tried it under 12V but the transistors pop in smoke instantly

I tried a resistor in series to limit current, and a 50k pot, but then the circuit doesn't light anymore ... do you have a suggestion ?
Did you get it to work under 12 V ?
Thanks for your videos,
David

Hello Stephenafreter

Your asking if I have my setup working under 12v?
I think you meant to say over 12v.
If that is so then NO.With the coil setup I have the transistors will blow as soon as I try it on 12v.
My setup works best with 6v to 9v.

Cascading Transistors

Hello everyone, just a quick note to say I was able to reach undetectably low amp draws on the "Simple sec" circuit with the following change;

1. 2 in1418 diodes and a green LED between emitter and base of first transistor.
2. Parallel to the above was the extra transistor, connected collector to base, base to emitter.
3. Both output wires to trays were wrapped around each other for capacitive coupling, connected to turkey pans separated by a block of wood.

Its nice to have the LED between emitter and base so you know when the circuit is oscillating and how strong, while the schematic that I saw had no LED... For me when I tried that, the extra transistor increased amp draw, but when I added the LED and diodes, I got a stronger field and much less amp draw. I dont know... For me I need both?

I would add another transistor in parallel but I wouldn't be able to measure it if draw decreased any!

Cheers

Thanks. That is great news. Is there any way you can post a circuit diagram?

Notice the leds difference from my pic and johnny's


IN4148 diodes

Not that much of a difference but its how I got it to work :-)
I still think the biggest factor in amp draw is your positioning of wires and masses.

Goodluck

CosmicFarmer was able to get a large reduction in current draw using the following addition to the slayer007 SEC circuit. When I tried it with a 6 volt battery supply the current was 150 mA without the CosmicFarmer addition and 115 mA with the CosmicFarmer addition. So it really does decrease current draw. The output voltage appeared to be the same in both cases since both would light a fluorescent tube.

Great work Cosmicfarmer and thanks for sharing your results here.This is great that you are seeing the same current reduction effect that i am seeing along with the increase in performance and Xee2 seems to have had a similar experience.
My own experiments suggest i could run three simple sec circuits for the same current draw it normally takes to run one so i think this floating transistor/diodes mod wants a closer look and maybe someone could scope it and explain the results for the scope illiterate and i include myself in that catagory .Great work everyone.Jonny.

Actually Dr Stiffler uses these 3 for his protection diodes and lidmotor too, so I cant really accept this circuit change with my name. Its just what I consider your porthole into the oscillation chamber. Without it, power destroys the transistor. Somethings gotta be there, what I havnt seen yet is a charging battery :-)

@johnnydavro
this is what I mean series / parallel

I think you mean parallel because I tried series with 3 and it drew alot of power. I think it might work if I had a switching diode in there.

@Xee
.1 whole amp? Try having your output wires wrapped or near each other and see. wow this meter must be really fooled then, I need to make a test circuit or do that trick at electronics class told us to wrap the wire around the meter 5 times and divide by 5, or how many wraps your doing.

@All
The goal is to make this run on basically the right scrap metal, as has been demonstrated by slayer. YouTube - Exiter running off water battery.mov Wireless power from 2 metals hangin' out takin' a sauna in some acid.

I think your meter is correct. I am using a different coil. I think the coil coupling controls the current flow. Since I have more coupling, I have more current flow.

@Cosmicfarmer.The drawing on the left is correct showing the floating transistors in parallel.
I find that with each extra transistor i add,the current drops by 3-5mA.Jonny

Regarding tuning your circuit.Have you found that the output and performance is the same,every time you start it up and it is not drifting out of tune and maybe we can put a variable inductor in there for fine tuning and also is there any chance of making a vid of your experiment?Nice work .Jonny.

@jonnydavro - I've had no tuning issues with the toroid, I did with the other coils but I attribute that to the fact that they were haphazardly wound. The toroid is very tightly wound and stable, and comes on to the same state I left it in last. I've found a variable capacitor across the emitter and collector to be useful for tuning as well. some videos of my setup:

YouTube - Exciter with big toroid #1 - LED bulb
YouTube - Exciter with big toroid #2 - LED bulb & Fluorescent Tube
YouTube - Exciter with big toroid #3 - Filament bulb

@all - there are amazing things going on in this thread, keep it up!
