This is it !

Greg, sure, I'll rework the logic to use NAND.

About the gate charge thing, I wonder if putting a heatsink on the dip packaged version would help.

Farmhand, I just don't know enough about the idea of using a transistor to drain the gate charge to comment.

It would probably work with a high speed transistor. Whenever the MOSFET is off, the gate drain transistor should be on.

7imix, Thats exactly how it would work when the pulse hits the base of the transistor it turns off ( non conducting ) when the mosfet is on, and vice verser it creates a logic between them, I guess.

Do these high speed transistors exsist ? What about a tiny P channel Mosfet ?

I have no idea what all this below means. Don't try to explain it to me it'll become clear later. I hope.

Gmeast said,

@7imix: if you have the time could you show me what you would do to the SR circuit to turn it into a NAND gate circuit ... or did I misinterpret an earlier statement you made? I'm planning a final circuit now. What I am going to do is design around the concept of a "master" Logic Module with Phase Modules that 'plug' into/onto a parallel digital signal bus. It can expand to 'n' modules (using buffers past a certain number of phases). Maybe the phase modules should all have buffers to begin with ... I think so ... but there's no problems with the four I have right now ... gotta' think on that ... it's theoretical design vs practical design ... and power considerations too ... buffers use power.

Greg about the choke I think if we are going to use deductive or inductive reasoning to do it we need to use the same process that they used. They would have first had a working fully operational battery charger using two batteries first. Then they would have re-tuned and introduced the choke before turning the recovery output back to the source battery. I think thats how we should do it.

It's hard for me to try because I don't have reliable circuit to produce the desirable recovery output. The frequency changes with my circuits when I load the recovery in different ways, it's kinda hard.
Nothing i've tried so far has been succesfull. I still havn't tried the iron powder ring yet only ferite. There is still no garantee that with the correct circuit what i've already tried won't work I may have to try some things again.

I feel a bit like a third wheel again, we just need to keep being methodical and inventive.

Cheers

P.S. The choke is a Non Hertizan or "LE" filter/converter type thingy as opposed to an "RF" Filter, if that is a better way to think of it. Just a thought.

Hi 7imix,

That's great ... thanks. I downloaded (I think) a pretty nice logic gate simulator, but I don't know the methodology, technique, procedure or whatever to use the simulator to create an original gate circuit ... other than intuition and/or trial and error. I loaded your 'original' into it and it's pretty cool. Perhaps a more sophisticated simulator is required to do what you did.

Thanks again.

What sim did you find?

If you search the net there should be examples of other types of gates constructed using NAND... That's all I'm going to do, find those and substitute.

[sucahyo]

Farmhand, can you try 925Hz ?


I wonder if it is possible to replicate 7imix waveform with your toroid, creating sine wave from the spike:

Hi 7imix,

I found this:

Logic Gate Simulator

It's kind of cool, but I really don't know if this is just a 'bare bones' simulator or what.

Thanks. Later

I wonder if it is possible to replicate 7imix waveform with your toroid, creating sine wave from the spike:

Hi sucahyo, Yes I think i can get it stable at that frequency with a nice short sharp pulse. I'll try to do it tonight and try some choke's at that frequency.

I don't really want to remove the small Iron powder rings from the board I was going to, it's a switching 12 volt power supply 5 amp also with filtered 220v outputs. But it has a faulty resitor, the resitor got hot and burned the board when it burned out I think it was a bad soldered joint. Maybe i can fix it.

So I will find another one if I can, i've got a lot of old boards I think all the painted core's are I powder. Not sure.

What is the significance of 925 Hz sucahyo ? Seems a familiar frequency.

I haven't been game to scope the secondary yet but i'll bet my lefy it shows a sine wave there at some frequency. The commercial toroid did, it's in the vid. Not sure how it does it maybe toroids are good for making sinewaves. Not sure if there was a negative componant to the wave though.

Cheers

NAND SR circuit

@ 7imix: Check this out. I've run this through my sim and it seems to work. I'll now try it in the circuit. It has an inverter in it, but I use another inverter elsewhere in the circuit anyhow. As you indicated in an earlier post, a NAND with the inputs tied together works as an inverter ... so, I have options. Here it is:

Hi all,

Well that NAND gate circuit didn't work after all at lower frequencies. So I went back to the simulator and guess what? I removed the NOT gate and switched the rolls of R & S and it works with ONLY a NAND gate Latch. How about that? That means there are only two (2) compound logic gates to do very critical timing job. Believe it or not, this was a critical circuit .... HOORAY! for real this time.

Here's the one we'll use:

Onward and upward!

Wow... That's awesome!

[Farmhand]

Hey guys what will happen if I put a few turns, about 6 or 7 around the recovery choke and connect an LED to it ?

Might take some sting out of it's tail. Indicator light, might need a neon.

Cheers

Congratulation greg.

Hi sucahyo, Yes I think i can get it stable at that frequency with a nice short sharp pulse. I'll try to do it tonight and try some choke's at that frequency.

Thanks. 925Hz is taken from Tesla frequency reference. Tesla just mention it as example but ATREE inventor take it as clue to produce working converter.

925Hz seems work as attractor. If aether see your toroid interesting, driving with 925Hz may show some new wave.

Hi all,

Thanks sucahyo.

@ everyone: If 925Hz seems important, then we will need to got 12-bit on the controller. That's not hard to do. 8-bit X 1usec has a low frequency limit of 3906.25Hz. Now's the time to make that decision if 925Hz X 1usec is desired.

Gmeast, I actually have been working with a circuit that takes any duty cycle wave and turns it into a short pulse. I found it in my electronics book. Just take the output and run it into an AND gate, and then also run the output through an inverter, or any odd number of inverters, and put the result of that into the other input of the AND gate. For a brief moment, before the inverter propagation delay time is over, the output of the AND gate will be high. After the inverter flips, the gate will go low.

It works really well. I'll post a diagram tomorrow.

Farmhand you should try this trick with your desulfator to get short pulses...

Can we use any off the shelf flip flop ics since we only need a flip flop now? I only have jk and d flip flop ics, not sr ones, though. I'll have to learn more about them.
