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

@ ivconic
Sorry I had totally forgotten to watch your 4 youtube clips but meanwhile I did and I must say:
Good job!
I just hope you and the users of the Vesta (Westa, pronounced like vase and not face or phase)
will not find too many cooking pots, rusty kitchen knifes and lost stuff from playing kids! *just joking*

No, seriously, I'm impressed by the in air test results. And the reaction speed also is not so slow
as I thought. The distance is comparable with a non-motion IB detector. At least in air.

Thank you for the test info's - I would assume that with the same coil size you might get
the same test results as with the Deus but of course for the Deus no 50cm coil exists.

What's somehow unpractical is that there is either an audio ouput or no at all,
even at highest sensitivity settings. This can lead to false signals or to a lost of depth
because the "chemistry inbetween" remains inaudible.


About the power-drain:
Thanx @ jladre for the info - depending on how much the backlighted dot-matrix display and the
audio output consumes we might have around 40mA for the EM-field - not very much.
The rest is needed by the chip and circuit. And it also means that you can use
a single pack of 2100mA accu-cells in series for ca. 23 to 30 hours (70-90 mA).

Of course someone should switch off the LCD backlight while hunting for a better battery-life.

However, most PIs "drink" 5 times the amount of this juice so the felezjoo has to compensate the
weaker magnetical pulses by its sensitivity which can be hard if the soil mineralization is mixed
or if it comes to deeper objects below a thicker mineralization layer.
The weaker the EM pulses the stronger is the shielding effect of the ground.
Is it immune regarding heavier electro smog sources? Still an unknown variable.

And how this detector behaves completly covered by salt-water is a completely other question.

> Don't power it OFF after use and put it on power supply at home, when not in use.

Genious idea but it sounds funny "put it on power supply at home".

And what is jladre doing if the batteries run empty while searching?

Typo. I mean battery charger and not power supply.
It should be designed in a way that it works (or is in sleep or standby mode) between charging.
I doubt that anyone is capable of continuous dive so long to run out of batteries.
Ivconic reports days of use without needs to recharging.

"And how this detector behaves completly covered by salt-water is a completely other question."

@funfinder.. This machine works the same in medium mineralized soil and under sea water. All my machined is used for hunting under sea water.

[Funfinder]

jladre, maybe you can make the eeprom area of the chip on-off switchable.
If the eeprom chip is separate.
After the settings have been saved you switch it to write-protected.
Now the firmware only can load the user-data from there but no longer is
able to update the "death-counter" !

Thanks for the saltwater info.

@ WM6
Of course you're right, the battery usually will not be empty if he's for some hours under water.
The main thing is how to keep only the chip on low power running.
I guess you have to force it by special commands into standby-mode.

Another method would be a switch that cuts off everything than the chip from power.

Or maybe the IC-socket can be placed inside of the waterproved battery-housing
which he has to open anyway now and then - so he can replace it from there
without opening the sealed detector completly.

And last but not least perhaps he can buy from ivconic a special version of this detector!

Another idea: combining a small solar-energy LiPo power-bank with the detector.

I have one and it worked already successful with the Garrett Ace 250.
This way the detector only has to be stored at a bright place.

It is a good idea! I think i can built in this solar power bank to upper surface of my enclosure..it could also charge the md while in used..so recharging will be less.

Isn't induction charging the go these days?

Make a charging pad that you clip to the coil and charge via the coil.

[Davor]

I'd do that for an underwater detector. The losses in such charging make only for the completely sealed and intrinsic devices to be charged this way. For that purpose I'd need some batteries with completely intrinsic chemistry, e.g. those that do not release gasses while charging/discharging. If anyone is an expert in batteries' chemistry, please step in

[jladre]

Li-poly battery will work. Like those of mobile phone..they can take charging while in used. They also portable and high power density.

20+ hours of detecting fun: 11.1V 5200 mA http://store.dji.com/product/intelligent-battery
Bit pricey at €100 but it delivers unlike chinese fakes.

You also missed to see explanation of what "Vesta" means, i posted it below that post, here it is again;

Vesta (Latin pronunciation: [ˈwɛsta]) is the virgin goddess of the hearth, home, and family in Roman religion. Vesta's presence is symbolized by the sacred fire that burned at her hearth and temples.

I have made only 2 devices so far, one for me and one for my good friend.
I intend to make few more in the future.
Videos i am posting above are not prepared for exact Youtube demonstrations, those are just my "working" videos which i made in process of experimenting.
But right now i don't have better videos, so those will hopefully be illustrative enough.
Yes; it is having discrimination! And it is not worse nor better than what we can see on other discriminative PI detectors on market today (except maybe few top notched models made by ML).
Front panel is made for another type of PI which i am making recently , but i used those because i have no time to make new ones; that's the reason for label "Vesta".

(Vesta (Latin pronunciation: [ˈwɛsta]) is the virgin goddess of the hearth, home, and family in Roman religion)

Uuuh, balkanic hot-tempered mentality - the selection of your reply makes this loud and clear!
You think you must attack me here? No, I know, you just wanna make things clear so we make it!

Because if you provocate confrontation you can get it, and if you feel offended by my Vesta arguments - lets make things straight!
btw. I thought that you with your many "roll on the floor smiley's" would understand some humor! Disappointing or even sad!



Now about the things you throw me on my head:

1st:
I did not missed your videos, I just said that to be friendly. In fact I had other (perhaps more important) things to do.

2nd:
In the first time YOU MISSED to write the real important second part:
"Vesta's presence is symbolized by the sacred fire that burned at her hearth and temples."

Or do you think that everyone here is an expert in roman gods? Shurely not!

Now the name of your detectors has really some fascinating value and is not just for "house-wifes" !
This is like the fire-adoring religion of the Yezides. There was one earth-gas flame that was protected
and worshiped in the north of Iran (near a volcanic region) which burned for over 600 years !!!!

You have to tell me or us the things which are really counts for you because we are no fortune-tellers!
Only the LRL-lunatics know exactly what someone really means and thinks and where all the treasures are!

Personally I give a sh*t about all gods as long as there exists no proven evidence!
And it never will exist !!!
Especially about all those 1000s of antique deities which have been invented for every worthless crap!

But the imagination that your detectors create the fire within the soil that is able to discovers the treasures
has a high sentimental value and can bring up a great imaginational picture!

But stop talking about hearths (german: Herd), family and kitchen if you want respect for the name Vesta!
Or do you wanna produce it for housewifes so they can find their fallen down spoons?

You also could call it "Lava" as the real hot and fascinating "blood of the earth".
But some german porno movie company once had this name so it might be not the best choice!

btw. your reply to me was completly offtopic, you better would have helped jladre!

And if the creator of the felezjoo is happy if you put it in a wrong labeled housing is another question
but you have explained in this case the reason why correctly so I won't say anything about it.

And now let us work motivated and constructive here and forget about such personal "sentimentalities".

[ivconic]

"...you want some confrontation you can get it, if you feel offended ..."

Oh no, neither one of those.
No confrontation wanted here and i don't feel offended, by no means.
It's just less important details which are more like interesting trivia.
Vesta label is prepared for quite different detector that i am working on lately, not for copy of FelezJoo.
But in a hurry i used two of those front panels, don't have time to make them especially for FelezJoo.
...
I like History, especially ancient Greek and later Roman era. I like both their mythologies too.
It's a nice move to use names of their gods for detectors...
Besides: it makes much more sane logic to do that than to name detector with some funny name... let's see: "Justin Biber GL2 , Pulse Induction Technology" !!!!
See what i mean?
Or "G.Bush coin master"... or similar.
Even more crazy are the names with no meanings at all , like "Scrat, Sporf, Skruz, Muz..." etc...
At the end that's really trivial question. Most important is quality of the detector.

i use old batteries from laptop.
