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

[CDI]

Many of these batteries are stuffed with junk and a small battery <1000mA capacity. Use only good source for batteries, for example dedicated battery shop with good reputation.
Last purchase of batteries I spent 5$ a pop for 18650 - 2000mA and those are very good & heavy. If battery feels light, probably is filled with crap.

Exactly that batteries i tested. Cannot be worst.
Maybe is better solution to use LiPo battery from rc cars/planes, high quality and ultra lightweight.

I missed to see this:
" Jladre: hi ivconic! You dont need to turn it off and on just for balancing pupose, the push button switch for "down" direction is also the balancing key. Just push it anytime and machine will balance"

Thanks Jladre! I didn't know that!

I guess my batteries are of that kind... rubbish made in China!

Make it run on 12 volts and put the lead battery 12v 1,3A

For $10 000 man can buy 6 to 8 XP Deus-es, depends on options!
XP Deus with largest coil is deeeeeeep! And it barely overcomes the price of $1500.
Minelab Explorer SE with large coil is also deeeeeep! Not sure about price, but certainly is bellow $2000 range.
...
As i posted earlier; i made FelezJoo PI and tested it in details.
It performs bad and poor.
In air it is very interesting, but on real soil it is useless.
But i was deeply interested in it's code, and still am; because i am amazed with how much details are put and processed with moderate (if not weak and poor) Atmega328P.
Author did excellent job. "Digital" part of detector is very nice done. But analogue part is poor designed and useless in real world.
So, if we had source code here; we could gather all together here to improve it to perfection. It would be perfect "open source" project.
But now with attitude like this; this project is going nowhere. I don't see bright future for it. Because nobody is insane that much to pay such price.

my dear friend
I really do not understand what you mean!
As said many times, even in the blog the free version is adequate for personal use and
there are no restrictions on the possibilities and options.
If you need I tell you again:
for personal use Just a demo version is provided and Only to prevent abuse of the system by the vendors is limited to 300 times.
The base price is $ 10,000 for selling the original HEX file.
And it is not for personal use and is only for retailers and merchants.
First, this price is considered as a minimum and the designer does not agree with this price.
And second only to commercial exploitation with their name and title. This price is expensive?
Now I ask you:
Do you think that the price for ownership of the project and for Unlimited sale with Personalized name and title is expensive?
Then compared to known devices that can be bought cheaper but just could use it and have no plans to build it, really is ridiculous!
And about the circuit:
If you claim digital part is good and the circuit is poor well, not a debate.
You can check with a scope everything and if you know really what to do design another analog circuit that the output wave coordinates to the micro be similar to the current plan.
This work is as simple as possible by a person who claims to electronics without manipulation of digital part.
It is natural for the job you do not need to source!
Now you can also do a public and free job.
Good luck

Yeah you are right!

Hi dragomir! Can you share how to run this circuit with 12 volts battery? Because it detect low battery at 14 volts.

[dragomir]

Reduce the value of R19 and replace 7812 of 7809

Thank you my friend..i gonna try that.

As you maybe read so far; i said that am amazed of how much options and parameters are put in such moderate MCU as Atmega328p is.
That's on what i referred as excellent job. "Digital" part is not excellent, i don't know that as long as i don't have source to analyze it.
Obviously it is not done excellent because it is not working good. It has limitations. Some things could be done much better.
Asking $10 000 not for source code but for hex file without counter... is insane!
I am having hex code with cracked counter for free, why should i pay $10 000 for another hex code?
You don't believe me? Give me your address and i will send it to you as prof.
Cheers!

hi my friend
if you are sure about working do not pay

[kara1453]

do you have the software restriction-unlimited-ayrıml my-which version is good

[Orbit]

Boys from Serbia few are dangerous what is that you can not unlock

[ivconic]

hi my friend

It is working the same as non-cracked version.
100% the same.
Only difference is in disabled counter and each time it is switched ON; it displays "300", again and again.
I promised that to do at the beginning of the topic, haven't i?
My intentions are not bad and i respect copyright as long as it is legal and regular product from market.
But this is not the case to respect any of the moral, ethic and other laws.
Simply because it is put in public with schematic and hex code and AT THE SAME time on some "google site" is advertised for $10 000 for ONLY hex code without counter limits!?
That's insane.
Is it "open" project or is it commercial? Make up your mind.
In meantime , since it is already published on forums and made by many enthusiasts; now is totally unfair to come out and blackmail people for the code.
Mistakes were done at the very beginning. Not my mistakes.
...
Most proper an fair move would be to stop, rethink and offer to people simplest version of source code as open project. Since many are already interested and involved certain effort and money on that device.
That's how this idea will not fade out and that's how it will continue. More people are always smarter than one man.
More people here may be engaged in improving it further. I bet there are highly skilled experts and programmers here which are able to solve all the issues at code and make it much better.
But it's ok, never mind. This is one of those "many" projects we've seen so far so many times before.
Everything is COOL.
Cheers!

Hi, this circuit is sınırsızmı-I need to make a clear distinction-which version
