Bloch wall disconnect and reconnect. The final design!

otto,

I have old impulse generator from 1975, heavy one which has additional ground cable. Do you think it may work well when not grounded ?

Hello all,

guys,

that we understand us corectly:I dont say that a 555 is a must but as I see its a good IC to get square waves.

The main point is in the MOSFET DRIVER that is connected to the output of such a 555. Or another IC that can give the square waves.

Hmmmm....hard to describe.....we need signals in our coils that are in 1 moment positive and in the next they are negative. Kicks of course. The positive and negative kicks not in the same time.

I was totally desperate and connected a 4007 IC to the 555. The 4007 has 3 pairs of PNP/NPN MOSFETs inside. Of course this was not working but I saw fantastic signals.

And I forgot to mention:

with 2 frequencies I see 3 sorts of kicks:

1. very fast perfect kicks fast ON/OFF times
totally useless to get even 1W of power on a bulb. See,Im talking about power.
2. kicks with a very fast ON time but the OFF showes a square wave
also totally useless when we talk about power on a bulb.
3. kicks that look like hmmm.....they are in a tornado. They are not straight like normal kicks. They are a little bit ....never seen this but I know what they are. Notto mention how such kicks sounds on my radio. Scary. Somehow I have the impression that they are "gliding" on ice. Never mind.
This kicks are also useless wehn we talk about power on a bulb.

Now you maybe wonder what Im wrighting.

The point is that not 1 of the frequencies when used seperatly will give any output power from my TPU.

But when I use 2 frequencies I have a full light. Yes, the current is high, maybe 2A at 24V but it doesnt matter how much current is used.

Forgot to say: Im measuring with my scope 250VDC. I made such controls because I dont see a need for a high voltage in my coils.Im talking about a ECD TPU.

@forest

look inside this generator and look whats the output. Oridinary transistors I suppose. Thats NOT good enough.

  @Gk & All:
     The Alex Jones Show discussion about the Petrolium leak in the Gulf, that Mk1 has posted the link on,  I suggest that everybody get informed ASPS. It is absolutely fritghtening what is going on there. It is much worse than publicized, and getting worse by the minute. It is the worse catastrophy in history.  And you my friend (Gk) were right again.  This will have unimaginable concequeces.

  Guys:  Sorry about my spelling, just waking up, or I should I say did not sleep at all.  Will post again, later. It's 5 am here.
