Bloch wall disconnect and reconnect. The final design!

@GK, it is said to keep the TC supply at 90 degree to the bifilar coils, not totally sure why, yet, but thought I would mention it. Keep the TC coil vertical #1, and the generator coils, #2 horizontal.

I was tickling the coils I made with a Car ignition coil and running a stranded speaker wire pair thru the core, registers about 1v AC, if I placed the DVM leads on separate leads (isolated) and touched the other free end of one of the leads to the driving battery the voltage jumps to 10V, perhaps feedback from the control module. Need to scope the PS leads  (12vdc 20ah battery) the trigger is a old RCA audio generator which I had running at 60hz   so the DVM should be accurate.

Hi GK,

I suppose you have seen the new Don Smith video's on youtube? 

Well he mentions a power supply, that he says is OU to start with.  I went and found the exact one he uses, and from the numbers posted, if true, would be correct.  12 watts input and 20 watts output. 

Anyway, I have ordered one to have for future experiments, and you have worked more with HV then anyone else that I know, except maybe Moby.  So here is the info if you are interested in buying one and testing it out...They are very cheap!

Specifications: Input: 12 Vdc @ 1 Amp (Suggested power source CAT# DCTX-1215). Output: 2,000 Vac @ 10 mA. Open circuit voltage: 3,000 Vac 30Khz. Short circuit current: 15 mA. UL.

Kind regards,

Glad to see things are getting close with Don's concepts as I think they work but most are changed just enough to keep replication difficult. 
   I did read one time recently though that he was incorrect on those transformers being OU.  It is simply a misinterpretation of how they are rated by the manufacturer.  It was explained in detail although I don't recall where.  Just don't expect OU from the transformer itself.

Hi Steven,

Hopefully you are the real SM and not an alterego? lol

When can you revel any further "secrets"?

Thanks, Gyula

Interesting, using the above design, the output waveform has a peak to peak value of 386vac @ 6khz, this is coincidentally the driving frequency of the HV coil. If I take off the ground the frequency changes, no surprise here. If I open the lamp circuit (switched lamp base), it changes the operating resonance. What I found interesting though is that the wire through the core was 16ga speaker (copper), if I changed that to a 4Ga copper, the output increases to 580vac!

Now I need to throw in some diodes and a few caps since I have none in the circuit currently.

Still no lamp lighting so I need to rectify the HV for pulsed DC operation to see if this changes.

More to come when I have something to report.


Steve, Thanks for the post.
