NFIP

No were certainly not talking about Ions here,that's been beaten to death on the Remote Sensing. Were talking about metallic particles such as veins or placer deposits or if your interested in treasure hunting metallic objects of value.

The signal source is of course the whats provided for us in nature via lightning strikes primarily which do have harmonics as you're aware and so this is where comparing the phases comes into play. From the Geophysical papers I've studied on the subject, the main energy is good up to about 10 KHZ.

I don't know about mentioning anything about a 4013 or a 4053, but the new 8051 varients are very powerfull and as you know, because of them being around so long there is a tremendous amount of usable code out there (check out www.8052.com).

I mentioned the 4046 (and it's new improved version by Philips) as a test unit,quick and dirty but does the job.

I am not a programmer,my experience lies in RF and analog signal processing (filters,delay lines,Receiver/Transmitter design,etc.).

I like Mr. Barringers conclusion that after all's he's tried, using the naturally occurring signals provides much more depth and not having to bother with a transmitter also makes the system lighter too.

For now I plan on designing and building a Pulse Induction Two-Box detector with a phase based rough target identification. I'm working on an Ancient River Deposit where the bedrock surfaces in a few places and then goes down to 200'. LARGE nuggets weighing as much a pound came out of this deposit and so my quest is to locate the most likely place where trenching down I could follow the bedrock's slope down.

Designing and building an NFIP system would be next as I will need the penetration of overburden beyond what the 2 box PI and magnetometer will show.

What's your interest in all this?

Demod

Hi Randy,

I brought up the 4013/53 part in

relation to demods, think you mentioned

diode demod in the Nexus. I never got to

finish as the thread Halo-ed out into the weeds.

Pages worth.

Now one way to receive low frequencies is to up convert

{modulate} them into a frequency for which we can get

narrow filters and then demodulate them back or

just detect.

So demod story may not be over.

I used the old Motorola 4066 phase/frequency part

not sure on the new improved philips part. Now

remember phase detectors are also sensitive to

frequency differences as well. {on the earth thing

with many frequencies coming in}

On a two box PI, that is an interesting concept,

figuring out the phase that is.

You may have something there. discrimination.

My interest in this is fun. and recreation.

Oh know lots of treasure stories over the years

but found I could make a lot more gold {alchemey}

with my knowledge of electronics.

And do it indoors, sitting on my rear.

Understand there are ancient gold laden stream beds

which now get cross cut by small arroyos that bring

out the gold. Yes the trick is to find the "ancient" stream

running and dig that up.

Back on the earth detector, what from your studies

would you recommend building?

many frequencies, which ones, how wide bandwidth.

Btw, I mainly do analog design, but have programmed

computers, microprocessors, and even wrote

Microcode for a bit slice processor 32 bit AMD2903 family

I designed back in 79.

So don't be bashful.

Micro

Hi Randy,

Reread your post there.

I haven't done the 8051 personally,

Have some engineer friends {I know alot of engineers}

who have for years. It used to be what we called

a Microcontroller, now it is getting very fast. You are

wise to stick to something for which the support software

has been tested and debugged. These same guys were

getting excited about a super fast Z80 as well. It also has

alot of support software that you can get for free.

Hey whatever crunches your numbers.

micro

Hey Randy,

Take a look at Silicon Laboratories

C8051F064 thru 067 parts.

They have a 16 bit 1 Megasample/sec A/D.

Of course few 16 bit coverters are accurate to 16 bits.

But this is not bad, and can do conversions and get data

at 1 us intervals. i.e. digitize PI return pulse, then process

before next pulse.

get alot in one package for 20 bucks.

take a look, digikey sales them.

LF Communications

When designing LF receiving

circuits need to be aware of

LF Comm stations. Some of

the treasure toys such as

Goldy Gun may use these.

LORAN-C transmitters operate at peak powers of 100 kilowatts to four megawatts, comparable to longwave broadcasting stations.

Watch the Patents

not all patents are true.

Yes I know it is in writting.

But still not always true.

Sandia National Laboratory bought a “LifeGuard” machine from DKL Inc., which holds patent 5,748,088 for this device said to be able to detect “entities” by “dielectrokinesis” at distances of up to 600 meters. Sandia’s tests and tear-down of the “LifeGuard” showed that it didn’t work as claimed and was essentially nothing but a fancy dowsing rod. But, of course, the company “stands by the product,” notes Voss, and quotes a DKL engineer as dismissing the Sandia work as “rubbish.”

A Real patent

TC1 that's true that some patents are false. In the case of Mr. Barringer there's no comparing him to the idiot that patented the device you mentioned. Go to Wikipedia and type in Anthony R. Barringer sometime, this man wrote the book on credibility. At his old age he would not want to leave this world known for a hoax .

I may be a little slow in replying as I had major shoulder surgery yesterday,so besides being loaded on oxycodone , I'm typing with the wrong hand .

...

Hi Randy,

No I just came across this

patent thing in relation to

another subject device.

Not Barringer.

He deserves a better look.

Hope your surgery went ok.

What did you think of the processor?

Cheaper than a high speed 16 bit A/D

and you get some processing with it.

Really worth a look.

Let me know what you think.

I have the habit of addressing

many things at once which can get

a little mixed up.

New 8051

Yes that is just the ticket for my project. Back in 1999 I had gotten halfway thru this fantastic book on programming the 8051 in Assembler. Being a hardware guy I fell in love with Asm and it's my personel opinion that if Jesus was on earth today and was a programmer-he would prefer asm! No blasphemey intended by the way as when Jesus was on earth he was a carpenter-if it were today he might have gone into computers for a living instead who knows?

At anyrate, as I get to that point will look into a development kit.

Yes Just the Ticket

Hi Seden,

Yes that processor with the A/D is actually

the ticket for alot of these projects.

Has been for some years.

Not sure who realized it.

Anyway you have to digitize the noise

to reduce it by adding and dividing {averaging}

really really need 16 bit converter though it

can be done with less.

Assembly, of course, not going to throw that

speed away by compiling it into something

you can't time. Timing is of course also important.

Which means all we needs is a good assemblier.

Not a problem. Oh and you can download the

real data sheet and look at the timing on the

processor. It's kinda long but easy to understand.

want to get fancy might add a good mathcoprocessor.

You got any idea on a good mathcoprocessor?
