EXTRA_EXTRA_DEEP DISCRIMINATING DETECTOR

[IBGold]

Hi Tinkerer,
I can supply scope shots of what it should look like and what it does but before we go there let me do some more testing as today I was playing with a standard 11" DD and got a similar response when I put the coil near my metal rubbish bin and I now think the coils may be overloading due to the reo mesh in the floor and the metal tube rack above my test area both are about 1 meter away maybe these coils are more sensitive than I thought I think outdoor testing is in order as these coils are all 18" coils.
I look forward to receiving your email address must go it is tea time.
Regards, Ian.

Got it talk to you tomorrow.

One meter is a short distance for a 18" coil. The response of these metal objects will definitely bring the signal near or through the ceiling.

This is again a matter of dynamic range.

As the sensitivity of the detectors increases, the dynamic range needs to be extended. There have been a few mentions of it on the forum, (JLKing, AGC) but a thorough analysis and discussion of how best to increase the dynamic range would be helpful.

This is a completed project? You can heat the soldering iron? HEX file will be? There are videos of the device?

Still working on it. This hybrid design is different from anything else, so every solution needs to be invented and tested. The TX board works, after a few minor changes. (ah, by the way, there are some mistakes on the schematic above)

The results are very promising. Tested with difficult to detect non magnetic stainless steel.

About soldering.

I like the ground plane like I show on the PCB above. The etching went fine, only a few spots where the Laser toner was porous and the acid got through to the copper.

I left 20 mils space around the traces and pads, but should have left more for my old shaky hands and not so good eyes. The high Flyback voltage deserves more space too.

The Hex file? No problem, if and when the design will be available in kit form, it will be complete with all the necessary information.

How much longer to wait? The new season begins, and such a wonderful device is not built ... It's time to move from theory to practice ...

Hi smity,
thank you for your interest in the XXD detector.
I am sorry to disappoint you, but I sold the design.

If you are really interested in an extraordinary detector, you can participate in the creation of my next design, the GOLDEN RETRIEVER.

As the name implies, this detector will be optimized for finding gold in every form and alloy, meaning it will find nuggets in highly mineralized soils, as well as a tiny 10 carat gold ear ring on the beach.

I am sure you are aware that the development of new technology in metal detecting is very time consuming. Therefore I make the following offer:

The people who actively participate in the development of the GOLDEN RETRIEVER, will get the first chance to try it and to buy it.

Stop, stop, stop ... How is it sold? You have completed this project? Where the result? Video? Or is it exclusive development? Each customer a separate device ...? And what about the other forum? I'm afraid that your project is a new one will see and will not be able to feel in practice ... But I wish you good luck ... At the expense of buying, do not know ... postage costs will probably like ACE250.

Dear smity,

I live in one of the communist paradise, where there is no postal service to send a detector out of the country and extremely expensive to have parts sent in to.

Therefore I do not manufacture any products.

I enjoy designing metal detectors, build a breadboard prototype for testing, and then tear down everything to use the parts for the next design. You know, in old TV's and power supplies one can find a lot of usable parts.

The XXD design looked very promising so somebody bought the design, for their exclusive use.
So now I start a new design. The good thing about that, is that with every design I learn more, so they get better and better.

Years ago I made an open source design, but found little interest in people to contribute to the design, but if you are interested, you can look at the:

Sorry to hear you sold the rights Tinkerer, maybe you would've sold 100's of kits over the next few years and made lots of people very happy,
now perhaps it's in the hands of a greedy manufacturer who will get very rich and rolled in doe

How does Tinkerer's IB-PI compare as respects depth and sensitivity?
Will the XXXDDD be the same as the Golden Retriever?

Regards
Kev.

Hello if this detector a known in the country,whether there is a video clip ,to see how it works ,to see how it works .If you can be a coin of 23mm nickel or bronze to see the country ,at 40 to 47cm, each cast In addition to the influence of the country ok and have at least the relative discrimination .

Hi Kev,

I am not in the manufacturing business, nor in sales. I only enjoy designing the best metal detector.

The Tinkerer's IB-PI is a good learning platform, but not for beginners. It has good discrimination and sensitivity. I learned a lot myself while designing it.

I have not decided yet which specific features to optimize in the GOLDEN RETRIEVER.

What features would YOU like to see in it? You say maybe hundreds of people would be happy to buy a kit over the years. What feature would these people like to have in the kit?

Hi Orbit,

I am sorry, the translation is difficult to understand. There is no Video. there is no more EXTRA EXTRA DEEP DISCRIMINATING DETECTOR available. SOLD OUT

Hi Tinkerer,
When I read that you'd sold the XXD, I just thought of Trevor Hill and his Gold PIC, he has a simple website, and has been happily supplying kits from there for years. A PCB pre-programed fused PIC, and the rest of the BOM, I'm not even sure if he supplies the enclosure. He must've sold 100's over the years, with very little overhead, and there are some happy folk out there using them.

I'm happy for you though Sir, I just hope they paid you well
When I retire I too will have the time to do as you have done and fully immerse myself.

I think that you should continue to pursue the goal you've already set yourself i.e. 1 euro @ 1 metre.
Even if you only achieve 75cms you will have made an impressive achievement and you will be able to take a holiday down-under and mop up some of those whoppers in the golden triangle - Doug will show you where to look.

I think if I, or anyone else here, were to experiment with the library of ideas you've posted here, and
we paid very close attention to detail then we could arrive at a similar performance level of the XXD.

As for the Golden Retriever, I agree with your first PRD that it should be optimized for gold, either native or small coinage such as pre-Roman. Native gold nuggets will be a challenge since many of the nuggets remaining on established goldfields have a decay characteristic that mimics the ground, even to the point that they maybe only 10 or so centimetres deep.

I have one area in mind where the ground is littered with small bits of iron which is masking a deeper layer of nuggets, too winkle in amongst that maze and cherry pick the Au would be very nice, and reasons such as this is driving me to experiment with your design. I think because you have been willing to stray outside the normal, and have tried different things your designs are breaking new boundaries.

I don't know if I'd have much to contribute to the Retriever at this point, but I believe that if a group of people in unison build the machine as the design progresses, and they share notes and observations of its performance, then new ideas will flow, and progress will be swift.

Best wishes.
Kev.

Hi Kev,

thank you for your kind words.
Trevor Hill with the Goldpic 3, did a great job. Carl Moreland did a fantastic job with the several Hammer Heads.
But you can see from the little interest in the HH2 and HH3, that there are very few people out there who want to experiment with new and different detectors.

Very few people want to put their money into innovations.

If you think that a specific design would be a significant improvement over existing detectors and would be a good business to produce and sell, why do you not pursue this avenue? Do what needs to be done. Get rich on it!!!!

I am willing to help you getting there, but at my age there is only so much I can do myself and, to restrict this a bit more, I only do what is fun for me to do. I have worked very hard for 55 years to get where I am now. The little time I have left, I want to enjoy.

I do enjoy solving problems, facing challenges. To succeed where others have failed makes me happy. So if you know what you want and have the will and stamina to work for it, I might help you, if you can make it fun for me.

And, NO, I do not want to go to Australia and clean out the gold fields.

All the best

Tinkerer
