Question about audio modulation

Of all only I wish you a healthy, new year 2009.


And now to my question:
What is better than "Vibrator":
A MOSFET or a transistor?
A MOSFET switches with power and a power transistor.
What is better suited?
I use a NE 555 oscilator since I have nothing better to hand at the moment.
The problem: Ever high frequency, the worse is the arc.
The start I had a 2N 3055 in it, which was not that hot with the huge heat sink but the results were not stunning. Then I got it there over time with the IRFP250 to try. It was almost like a wonder of the world for me as I thing that was and the zeilentrafo nearly 4 cm bow moved already powerful, I got the goose also me happy like a little kid :D

I run the whole thing with 25V / 1 .5a.
But I think I will finally build a clever oscilator. Which is the suitable for something like that?
Thats not so hard with the audiomodulation: the one pole to + and the other pole of the audioquelle on the 5.Pin of the NE 555. testing jobs
It's also but it does the above problem: if I so have set the frequency, that you listen to the music and is no Quitschen more involved, the arc is only thin and weak.
The kigt of the oscilator or? Of course, different Oszillatorschlatungen can be and use MOSFET driver with somewhat different results. But unfortunately, the main problem lies within the transmission characteristics of a Flyback transformers. This is optimized for operation at 15 kHz, which is hold in the audible range. Power transmission will soon significantly worse at higher carrier frequencies, I've found that at various different Flyback transformers. I had exactly the same problem with my connection and have chosen a compromise solution but then what a clean music playback allows, but with only about 1.5 cm plasma flame. If you need higher volume and still so you wouldn't have to go probably away from the transformer and more direction RF VTTC good sound quality,. With audio-modulated VTTC's apparently very good results can be achieved (I did however never tried it myself).

My version was a simple circuit TL494 and downstream ICL7667 with IRFP460 power amplifier. Yes, with LT 494 had I mind also what. I'm not only about the length of the arcs. It would be but also very if the quality is great and the ARC looks like nothing. My fettester and longest arc is currently with my transformer. Only with time, means he is getting smaller (he does not nartürlich). Even if is is videos anschaucht, where for example someone attracts 10 cm long and 2 cm wide arcs. Because comparing just know how small his results tenants actually are. It is a little disappointed, but it must be not discouraged. I think it's almost beautiful, if it is still open and not so dangerous at the beginning. For example me the transformer in the worst case brennts you keep holes in the finger and it beutelt one (in my case!). At a MOT your hand turns into a lump of coal and it is roasted. So an MOT is nartürlich already quite impressive. But you must don't begin. Prefer first of all start with small things and work langsamm up.


I am so far quite to peace with my body. They all have worked and deliver good results. "" And even though once something not right on straight away work, don't give up, so according to the motto: "Ah, crap is not" and then schmeisen in the corner.
Still time for look what it could be.
This is a small piece of advice for those who maybe sometimes so concerned with. You can handle so 10 cm long and 2 cm wide arcs actually only with an MOT.
Or you have the NT with a ZVS and pumping performance and I properly purely because no one answers me but need an answer, I'm now a double post, in the hope, answer to get:

I have taken up with the 555 Test equipment rentals once again and have now some questions about:

1 would it maybe eswas know if I an amplifier (so 1-2 Watt) with tuned suspension, which could be reinforced so the music that the whistling anything they drowned out or do not survive the timmer?

2. what brings a coupling capacitor parallel to audio source and also what improved?
