This is it !

If you try to substitute a NAND or NOR gate for a NOT gate make sure you short the two inputs of the gate together. This will make both inputs of the gate either 0 or 1 and if you look at the truth tables the output will therefore be either 1 or 0, like an inverter.

Also some gates have open collector outputs, which means the output needs to have either a pull up or pull down resistor to be able to source or sink current. I messed around with it for a while and just went back to using the inverters since they are so easy and convenient.

On another note, I also tried taking your desulfator and replacing one of the pots with a diode to make the pulse width as short as possible. It worked pretty well.

Hi 7imix thanks, you can see by the circuit all the input pins are shorted. Does this mean they should work the same ?

The diode idea makes good sense too i'll try that. Ta.

This has me baffled. I'll try again another time with the diode awell. Thanks.

3-phase

I want to apologize for the silly statements in my last posting regarding the duty cycle. I edited the posting accordingly.

Then I want to bring this to your attention:
Arduino - Wikipedia, the free encyclopedia
It is about a Europe based open source micro controller platform (but shipping world wide).
On the page is says:
.................................................. ........
I am optimistic that gmeast's effort to find a simple solution for the 3-phase driver will bring good results, but in case you want to move to micro controllers in the future, maybe the above would be an option.
Thanks.

Hi marxist,

Thanks allot for the vote of confidence. I've always said this thing would be easier with a micro but a dedicated digital circuit is worth a try. I will be one of the first, however, to dive into the micro-approach if I'm NOT successful at the dedicated-circuit-approach.

At present, things look very good. I would be on the last phase of this thing if it were not for having to wait nearly two weeks to acquire components I need once I've settled on a choice ... it's a logistics and $$$ thing.

I, for one, will explore the option you listed either way.

Thanks. Later

latch-reset

@ 7imix,

Once again, I am very grateful to you for taking the time to whip up that latch-reset logic gate circuit we will be using. It has made possible the use of a single-clock input that would have otherwise required three clock inputs ... one for the 'main clock', a second to shift 'data' onto the data pins and a third to 'load data' ... to say nothing of (also) needing a register that holds that data. Our way uses the latch-reset circuit to automatically 'load' data and force a reset at the right clock phase with just one pulse from the latch-reset circuit.

At the right time, I would like to review that latch-reset circuit and attempt to 'whittle it down a little' by identifying any possible redundancies ... but it may be perfect the way it is ... it's working spectacularly well!

Thanks again.

I'm not sure about that Greg but you have every right to protect your circuit.

So you may want to find out about that before posting it. I'll read the disclaimer sign up document and get back to you on that. Hold tight.

It could take a while. I have other work to do but it's too hot so i'll read it now.

Cheers

Hi Greg, I don't see anything in there that says they get rights over anything except for thier own defence.

Though you do realise that if you post a drawing in public it become's "in the public domain". "Free for all" I don't think anyone can claim it then. Not for patenting purposes anyway. PATENT LAW OUTLINE

Intelectual rights is a different thing, I realise that.

I would imagine you would have to sign a drawing with a statement declaring that you retain the intelectual rights to the item drawn. Maybe wittnessed and dated.

Caution

You guys do really have something here. It would be sad if you did post the schematic and then someone else ripped it off and patented it. That's what happened to Alan Francoure and his device THE INTERFERENCE DISK ELECTRIC GENERATOR BY ALAN L FRANCOEUR So you should be careful.

Hi FRC,

Thanks for the advice. I'm being very cautious.

toroid progress

Hi all,

Now that I have a 90% complete and tested circuit, I got back onto my toroid.

I nedded to verify once and for all and because I'm generally paranoid, that I had indeed wrapped the wire in the correct direction for the northern hemisphere before proceeding with the primaries. So ... I did some exploratory surgery on it. See the blood and guts here:

http://02d1852.netsolhost.com/radian...ry_surgery.JPG

It was wrapped in the correct direction. Had it been the wrong direction, I would have packed up and moved in with Farmhand in Australia.

I cut my primary wire into 3 equal lengths today. Now I needed to re-wrap the wire on their own spools. Any spools I have will wrap the wire too tightly I fear. The spool the wire came on has a nice big diameter, so I rewound all three segment back onto the same spool. So the wire just has 6 ends now. I have started laying out the pie shapes on the toroid according to the toroid guide's protractor. Will wind tomorrow.

P.S. I'm thinking of posting my progress video on our blog.

Hi Greg,

It was wrapped in the correct direction. Had it been the wrong direction, I would have packed up and moved in with Farmhand in Australia.

You would be very welcome here, imagine the things we could build. I don't recomend flying though I would come by boat in the calm season. Hahaha.

I had several pangs of paranoia and almost did that to mine, but I just kept telling myself I did it right over and over. I looked at my video and seen i did it right, strange looking back to check my own work on video.

But it is like you said as long as it's wound the right way we can flip it over and reverse the connections, but only because there is only one layer of turns if there was two or three layers one end would be the bottom of the coil the other the top.

Toroids are strange things. Strange is good.

I PM'd you Gmeast.

Cheers

Here's another scope shot, I managed to get all three coils pulsing at 93.07 Khz, going by the DMM. Not as good looking as the other one.

If those bouncing wave represent real current, then by using FWBR, you already had many times of gain already?

[7imix]

Hi guys. I have been a little discouraged lately because my dso nano is not fast enough for me to be able to measure these pulses properly. The dso quad is coming out and it has a much higher sample rate, but I'm completely broke at the moment. A friend of mine promised that he has an old scope in his garage that I can use but I haven't heard from him about it lately.

Anyway, I have been working on a number of different clocks, experimenting with the desulfator more, and experimenting with vanilla transistor bistable multivibrators. It's all good experience, anyway. I look forward to getting the money together to get some of those clock ics and some of the MOSFET drivers really soon.

multi-phase controller update

Hi Guys,

For the private viewers, I did make a wiring screw-up ... actually 2 of them on different parts of the controller circuitry ... I thought I had. Anyway, it looks sweet and clean now. Can' wait until the LTC6900's get here. I'm going to start on the Driver Chip after I make some turns on my primaries.

The latest video of the progress on my multi-phase pulse controller (for public viewing) is here:

Very impressive

I love it Greg, it's exactly what we need. Positive here or there adjustment and inbetween. Pure genius. I don't know what else to say it's perfect !

To tell you the truth if it works the same as the same sequence would with a micro it is much better. Would the power consumption be less too ? Not that it will matter.

Looking back now I am very happy we took it slow and were so methodical about our progress, it seems to be the only way. You should be very proud of your efforts Greg.

Excelent work.

[7imix]

I got an advance and ordered the DSO Quad, the clock chip we've been talking about, some MOSFETS, and some of the MOSFET drivers, both inverting and non-inverting. They should be here by the end of the week. I'm excited!!
