felezjoo PI(the best pulse induction metal detector that I made until now)

[6666]

Hi All

My UNO arrived today, just trying to get it to work, got a few LEDS flashing
if anybody is planning to buy a UNO, here is a tip buy a UNO that comes with the USB cord.

[6666]

Success , first blink program uploaded to UNO via IDE.
Software and drivers were easy to install on Win7
much more automated than shown on Arduino website
there are a couple of simple things that you MUST do to get working
will list them if anybody interested.

By far the best DIY or delta pulse, nothing can exceed the circuit it, FELEZJOOPI although the software circuit, but it does not fully identify iron, and its detection range is very small, so I recommend everyone to improve Delta pulse, I have FELEZJOOPI PCB document, the need can find me

Hi Liudengyuan


I fully endorse what you are saying...the the Delta Pulse 2 is still the number 1 PI for the Amateur Experimenter if he/she wants any semblance of a reasonably excellent PI metal detector for home and beach use.
The only other DIY PI metal detector that may come 'close' to the Delta Pulse 2 is probably the PIM 2, but the version .06 hex file is not freely available to the amatear experimenter, so I cannot say.
So I would conclude to say that if the Felezjoo PI would include a GUI with BAR indications like in the Delta Pulse 2 or PIM 2 then, maybe I would decide to build it, but otherwise I am still very happy with the Delta Pulse 2 which I successfully built way back in 2012.

Delta pulse is a very slow machine, even though it has a possibility to improve the speed it cannot defeat felezjoo pi.. Felezjoo pi is very versatile machine only if you build it properly. About the depth delta pulse cannot also defeat the felezjoo..i haved made both machine thats why i can compare. With a 1x1 meter coil you can detect a 4liter paint can at about 2.5 meters with a full setting sensitivity in air.

And also about iron identification it is better compare of that bar.. During my hunting i dont always look on the lcd. I just listen to my headphone and all target that have a cut off sound are trash and all that the sound remain is good.

Did people know, FELEZJOOPI is garbage, it is the Iranians used the gimmick, the delta pulse is the most used, FELEZJOOPI regardless of stability, probing depth, are far less than the delta pulse

[liudengyuan]

Delta circuit is only a classic, if you use microcontroller, delta pulse circuits can be designed, so I advise the whole world is interested in making friends, no need to concentrate on FELEZJOOPI above, you should Delta as the center to develop detection instrument

Hi liudingyuan! The way you talk is like you have a working delta pulse machine..if you really have one post a video to this forum..and make a test in that video that we will see how your machine work. We are not just about talking her but also providing an evidence..yes delta pulse is very powerful specially the delta pulse 3. But what you are reffering her is the classic one. Post a video man.

[6666]

Hang on a minute simply saying that the delta pulse is best is only just a random statement and meaningless,
you need to come up with data, like the type of target, size of target, coil size, depth of target, type of soil
battery voltage and a whole lot more.

[liudengyuan]

I just told you, FELEZ JOOPI delta pulse is better, if you do not believe you can go make contrast, we know in the end what kind of good,

If that so then, WHERE IS YOUR DELTA PULSE??? show unto us.. Or maybe you are just frustrated becàuse you dont have a working depth sensitivity pi

[dragomir]

Make clip delta pulse catch how and how discriminate small objects, coins, nails, to prove their capabilities.

The argument as to whether Delta Pulse or Felezjoo is the best detector is a pointless exercise.
As 6666 quite rightly says, your impression of the performance of the detector depends on the type of target you're searching for, the size of the intended target, coil diameter, depth of the target, soil mineralization, power consumption, user interface, weight, etc.

The Delta Pulse is a known good detector, primarily aimed at detecting large deep objects. It can also be used with a smaller coil for finding coin-sized targets, but is not suitable for searching for thin gold necklaces, or gold nuggets.
The Felezjoo is a fiddly detector to build (requiring special selection of certain components), and is also not suitable for low conductivity targets. It has some "claimed" capabilities at rejecting iron, but so far we haven't seen any test results. There is also the issue of the firmware timing out.
Hammerhead is a very good detector, mainly designed as a learning platform for PI technology. It's a complex design to build, but gives some excellent results once you can get your head around the many design options.
Both Surf-PI and Baracuda detectors are good for the beach, with relatively simple circuitry. But due to a lack of clear documentation, a number of beginners have struggled with the construction.
Minipulse Plus (MPP) is a modified Eric Foster design, with an upgraded dual preamp stage. This is the only design to allow searching for thin gold chains and gold nuggets. It has the best documentation of all the other DIY detectors.
However, none of these detectors have a ground balance facility, so heavily mineralized soil will be a problem in all cases. Although KRinaZ made some further enhancements to the MPP, and has been successfully searching for gold nuggets in Arizona.

So ... as you can see ... the answer of which is the best DIY PI detector is a personal one, not always driven by logic. Your preference could well be a subjective one.

Its not really about which of the two are the best but the real issue her is refering felezjoo to a garbage by liudunyuan "Did people know, FELEZJOOPI is garbage,"
As of the result of headache, patience and frustration of this project we have now a fully working machine. And that is why we cannot accept if somebody will say it is a garbage.. Because this machine is just few step behind to those discriminating pi in the market..
Anyway it is acceptable if the who said it is already produce his fully working self design pi.

"... is a pointless exercise..."
Correct. Usual story; "mine is bigger that yours".
In this particular case we still haven't seen what other side has to show here... except the constant spamming on multiple threads with various nonsenses.
Along with awful English and than is not understandable what the person want after all?

"...your impression of the performance of the detector depends on the type of target you're searching for, the size of the intended target, coil diameter, depth of the target, soil mineralization, power consumption, user interface, weight, etc..."
This is true and very important to understand.
Huge majority of people in md hobby are mixing frogs and turtles all the time.

"... It has some "claimed" capabilities at rejecting iron, but so far we haven't seen any test results..."
Seems you missed to see my videos? Though those are only skim demonstrations which i recorded only as a reminder during the process of adjusting the detectors.
Although it is not perfect (name me any other which is perfect) it DOES rejects iron. It does rejects iron in the air and in the soil, already checked, tested and proved.
But than... you have to make it to see that. Otherwise you may always have doubts in claims made by others.

"...However, none of these detectors have a ground balance facility..."
False!
FelezJoo PI is having GEB and it is working just fine.
Tested, checked and proved.
But than... you have to make it to see that. Otherwise you may always have doubts in claims made by others.


"...the answer of which is the best DIY PI detector is a personal one, not always driven by logic. Your preference could well be a subjective one..."
True, but this is strictly conditioned by what you stated previously:
"...your impression of the performance of the detector depends on the type of target you're searching for, the size of the intended target, coil diameter, depth of the target, soil mineralization, power consumption, user interface, weight, etc..."

If we choose and precisely define criteria; than we can get more accurate "picture" of what is better and what is not, we must beware again from mixing frogs and turtles.
FelezJoo PI is best PI detector that i made so far (that i have made so far; that's the claim. Not "the best PI" that was made... by any others),
according to this criteria;

1) Ease of making, relating to complexity of circuit...
2) Minimal number of parts.
3) Modern user interface, lot of options and adjustments, very precise (almost perfect) timings and behavior.
4) State of the art of coding.
5) Small and compact design, easy to pack and finalize it nice.
6) Extremely stiff, clear and fast response.
7) Rich variety of audio responses.
8 Wide range of adjustments; pps, delay etc.
9) Extreme depths on medium sized and large objects. (of course this demands proper adjustments and suitable coil)
10) Extreme sensitivity on smallest objects, coins, cash, jewelry (low conductive materials). - Completely opposite from what you stated here: "...and is also not suitable for low conductivity targets...".
Actually it is that versatile and rich in combinations of adjustments; that can be turned also to very suitable for low conductivity targets... of course followed by suitable coil for such task.
And i can name more points if you like.
But all this can be sublimated only in one word; versatility.
That's why it is the very best PI detector that i ever made; because it is the most versatile i ever made.
Hamerhead... i tried to make it twice, on second attempt i made it. Not bad, but sincerely not in this league.
SurfPi... also made several units, than i made my first Barracuda and that put the end on SurfPI story for me.
Minipulse Plus (MPP) i made only one so far. Not bad as hobby diy project, but far from being competitive with FelezJoo PI and Delta Pulse.
Delta Pulse... i made 76 copies so far. Very good with large coils, for large depths and on very large targets. Complex design with a lot of parts.
Now is second on my diy list, just after FelezJoo PI.
