Successful TPU-ECD replication !

[giantkiller]

Unfortunately I have allot to learn yet. I still want to stick with SS for now which I have started. I am trying to fuse, isolate the circuitry as best I can to prevent having to replace my MOSFETS.Using sine waves instead of square waves might help alleviate blowing up parts.

Is there an advantage to using iron wire as the collector as compared to copper?

Its great that there are people here that you can learn from.

2 things, Sir,
I am strictly SS. It works, square or sine. If you have noise that will trigger the FETS on also. That is the initial reason they fry. Try pull down res also on gates. Run with ATV batteries.
I used iron wire because SM mentioned it and I saw the application of a malleable, totally programmable core. I wanted to increase the copper mass in my next build back in Feb and was given warnings about the danger. After that the ECD appeared with smaller stranded collectors in the ECD model. See that? Then after that the PVC notched coil appears by Marco with a copper collector of smaller mass. See that?


JDO300 and I have FET driven ECDs by the ECD pdf spec. My driver circuitry is suspended in the middle while the pulse circuitry is external.

Here is a head start, Enjoy:



--giantkiller. I love uncontrolled power!

i know there is only 1 place to start and i aint saying it agin lol

well just 1 more time Tubes  in fact perhaps people wait for YOU the HERO to walk the path the right way lol


ist

the HERO  lies with in us all 

ahhhh gk

lol

so skip the tubes lol      but you must compleat at least 1 of sm's unit to understand it  then fumble around the finished unit it is a tricky one 

then  well  lol  hummmmm     remember thease words    SEEK AND YE SHALL FIND!!

But - I would like to say this:
My suggestion is to Forget about trying to create a Valve Oscillator - just for the short term.
Use your signal generator (sinewave) to do the frequency, and the amp for the power & robustness to deliver it to the coil.
This will save lots of time trying to create oscillators, and give you stable frequencies to test with.
- Just for Ease of use, and Time/Labor savings -

PS: I would NEVER mention Batteries...

oops wrong turn....
it is tubes you need.
and batteries too, no i mean two 
you need two seperate controllable DC sources.

This is important to create the MDC
The MDC is a polarized DC wave in one direction yet constantly changing.
It is a sine wave like classic AC but it never reverses.
MDC stands for MODULATED DIRECT CURRENT always dropping and rising but never reverses.

You can create this type of current simply by taking an AC wave and switch it in series with a DC source, the AC signal now simply ADDS on top of the DC source.
For example we take a 9 volt AC sine wave and we switch it in series with a 9 volt batterie,
The resulting wave will be cycling between zero and 18 volts but it will never REVERSE it's direction.
in other words ,it does not alternate like AC does , but it does cause induction ,the field is still always changing.

you cannot create an MDC wave with one source because you cannot add the same source in series with itself....this is why two DC sources are needed.

The output of the tpu was called ADC, Alternating Direct Current , i prefer to call it MDC

the same thing applies to tubes, some people forget tubes are still DIODES.
Diodes conduct in one way only.

if we want to amplify let's say a signal from a microphone, which puts out AC signal, we cannot feed this directly into the tube because it will only handle one half of the AC signal.

Therefore we switch in again the DC source in series with the mic so it becomes polarized and the AC signal simply adds to the DC and again we have our MDC which the tube can handle, it is always positive or negative.

The dancing magnet video i made was created with this type of current.
It was fed an AC 5 volt signal in series with a 12 volt DC current.
The resulting wave was cycling between + 7 and +17 volt always positive but yet it caused the effect.

@GK,
My images you posted are wrong.

when we get to the finished model shall we call it curculating current ?


hummmm     or natural current ?  hey why not go all the way and call it what it  is the wheel work of nature lol
