Open Metal Detector Project Charter

Or not... living in a crowded city gives you impression that the whole world is a terribly crowded place.

This sudden surge of money is a sore consequence of gold prices being ridiculously high. It is also localised to OZ and partly US, and nowhere to be seen in Europe. When gold frenzy dissipates, so will extra financials.

Don't get me wrong, niche markets are a fine way of earning steady profits, but don't confuse that with sudden stroke of luck.

Well, in the case of defending myself before I even start. I came here for support, not criticism. Yes a copyright. Detectormods can stuff it. I hope your coil co. chokes on it's profits. Yep. More money in selling the top-end BS than researching the direct results of coils on gold, for something other than a top-end detector. But we must all keep it hushy-hushy.. Hehehehehe!
GROW UP the lot of yez!
An AM radio detector will whip the arse off a ML on solid Ironstone. So shut yer yappin' cake-hole Mr corporate.
The demise of basic detector research was overlapped by the saturation of the Australian Goldfields with corporatism and micro-processor ignorance(very similar to the political ignorance we have.. )
As an example i will take a Lister 8hp motor, old water-cooled and push water 23km uphill 450m.
Then I will take a so-called "better" 2 cyl.,13hp air-cooled. AND IT WILL STALL.
This is the example I will give to the general Pulse Induction Tribe.
You have discarded the majority of your research material without proper digression.
For any real progress to be made the pre-conceptions, sterotypes and corporate dis-information must be bypassed.
There are absolutely billions of ideas that are made available for re-invention, by the progress of technology, and *******-patent lapse, and that scope of progression is open to the lateral thinkers. Patent merchants seek to inhibit progress for profit. That is wrong on a basic level.
This website commits itself to the salvation of PI. What an ignorant joke!
I do hope Davors positive help is not the exception here....

Tim, you speak of billions of ideas, my whole life is about finding such. Could you share a few, I have a feeling that T/R detectors were left before reaching full potential, but I am not a Guru. I am genuinely interested and would like to know your views. Are we of the same tribe?

[detectormods]

Well, The main Lynch pin of every ML detector is the ground balance offset patent that has expired, yes it is free to everyone to use.... Wow i just see so many designs coming onto the market...(NOT)

Have a think about it.... Pulse ........Ping.......Recovery.......Its about as difficult as making a ham sandwich.

Waiting for the the hmmm ML Killer.......zzzzzzzzzz are people that stupid that no one can beat a standard ML P.I detector... It really is pathetic. The crux patent has expired, the other patents are not the the performance barrier that you all fear.

Head down, bum up, make a better detector.

Davor, speaking of Black widow, a single fiber from a mature female web can be used to make a very sensitive mag field detector.

[Thomas]

detectormods, crux patent? I did a search and found nothing. Could you say more about it?

[WM6]

Crux can be deciphered from this: C.... .ru.. H

And Patent expired about: http://www.freepatentsonline.com/5506506.pdf

I had no idea. How?

[Thomas]

WM6, thanks much, very interesting! never heard of it before.

Davor, I'll gather up the info and post it.

[BILLY]

Detectormods where is that detector you were about to release several years ago?

I view patents as a legitimate way to protect an invention, but the process is now broken and being horribly abused. Copyrights do nothing for this purpose.

The only reason the gold detector market is going gangbusters (and not so much the last 2 years) is the price of gold. If gold fell to $500 the detector market would fall with it. And almost all of that market is in developing countries, not Australia or the US.

It seems simple that someone would come up with a competitive PI design, but so far no one has, either in corporate-land or homebrew-land. The companies who tried the hardest were Garrett and White's, but those efforts fell short. Why? I can only speak for White's since I was involved with them, and it was entirely a lack of manpower. All of the engineering staff was focused on bread-and-butter hobby detectors (the ones we knew would pay the utility bills) and PI was relegated to a spare-time project. Don't know about Garrett, but their bread-and-butter was security detectors, at least until the AT-Pro.

Several homebrewers have taken a stab at better-cheaper but nothing ever seems to emerge but boasting. In some cases they spent way too much time on public forums deriding the market leader for what purpose I can't fathom, even to the point of being slapped down with a lawsuit. In most cases there were delusions of grandeur of a single person being able to design, build, and market a world-class detector. Somewhere on these very forums are my 7 suggestions for success (or maybe 10, I don't remember), maybe it's time for a review.

Finally, this website commits itself to the dissemination and discussion of metal detector technology; nothing more, nothing less. Most people seem to be more interested in PI, probably because it's easier to homebrew, and a less mature technology.

P.S. -- "Billy:" continued provocation will earn you a permanent reprieve from this forum.

My preference of copyright is in terms of being a precedence instrument in case of litigation, and in a case you do have a copyrighted idea pre-dating any patent attempt - nothing can stop you from continuing production. It is true that when an idea flies in the public, even though it is automatically copyrighted, there is no stopping its further development and you can't sue anyone but the blatant copiers. But you are free to do with it whatever you want.
Provided of course it is originally yours.

[WM6]

Davor, is this still true in nowadays USA "first-to-file" patenting system?

[Davor]

Yes. You are supposed to list all prior art, and it can't include the exact idea that was already posted by someone else, as it is supposed to describe some original idea. Some people fail to list all prior art, and risk losing their patent - regardless of being granted.
When contemplating a patent, you must realise that it is only good as a litigation tool. If ever it comes to defend your right to produce whatever it is you do, and you do it based on your copyrighted material, there is no patent in the world, except maybe in Australia, that will ever win over your pre-dating solution.
If you still have any doubts, just visit https://www.patexia.com/ and see what sort of research they do
If anyone finds a source that describes a patent and pre-dates its precedence date, such patent is kaputt, out of order, not working, broken, good for nothing, defunct, and also finished off.

The only function of a patent nowadays is that it easily impresses simple people.
