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

[eclipse]

Eclipse what software and programmer did you use to burn the hex code ?
I tried Winavr and the bascom programmer but would not recognise the uC.

I used ExtremeBurner for USBasp and it worked smoothly.

I think there's a lot confusion in your mind going on. I'm not from Iran (nor bernete-one, I guess), also whats up with the hate??
If you need to display your hate against the designers (owners) of these LRL and PI I don't think you'll get satisfaction here, people in this forum aren't
interested in things like that. As you can see nobody in this topic has made false claims for the capabilities of this design, in fact I mentioned that I can't get more than 1 meter detection depth with my current coil, does this sound like advertising?
I appreciate your comments left in this topic but this last comment is scratching my nerves.

Mr.Qiaozhy

Sorry. Please accept my apologize if I write something not technical. Just once in brief.

Mr.eclipse

in one part you are right. yes, i must speak technically. so i apology. sorry.
also about your test, i forgot it to consider. again sorry. apology.
but You behaved exactly like other felezjoo members as I expected.
How did you quickly find out I hate its designer? (I'm not member of that place nor am Iranian. Hardly spent time and translated)
In their forum first any new post must observed and approved by the owner of forum then if it is on their taste they allow it to publish. Second, if accidentally or intentionally a criticism published, they accuse writer that you hate us you have enmity you are jealous of us then they ban his account. No other answer.
Through 1300 pages full of nonsense over there, have seen some sorrowful pages especially insulting geotech1 and calling old known hard working members here as a fake masters.( means uneducated people which don't know much)

No problem. I don't want to publish translation as it is their home their language but understood many things.

Mr.koohyar

I appreciate the last video you shared here. It is interesting.
I followed the link and found out video is not yours and belongs to someone named HAMED who is making detectors and selling chance pi and recently felezjoo pi.
Seems HAMED to be an honest person because he wrote some difficulties may encounter users through his forum. Here is a quote:
"for making such a large coils, I asked my friend to buy especial cable from Germany. You can't find it here… and…….."
It appears noise cancelling and detection depth is highly depends on special goods.
that video test performed by 60 cm diameter coil made by special type of cable.
Why you don't translate such these information?
should i search and explore that coil is 60cm and made by especial…..?????!!!!!!!!
When you say "the best metal detector have ever made", you make yourself responsible.

Mr.bernte-one

You ask and provoke people to build one and not ask questions!!!!!!!! Why????
While even its designer refuses to show us his device, refuses to clarify some subjects, you ask members to just follow????? You want just "follow us" "like us" without thinking!!!!!
When I asked micheal to make a clear test he said" we test at night and can not record…"
What an amazing reason. Here is night !!!!!!!!!

Geotech1 is known globally and has internationally influences.
You don't imagine any wrong information how affects enthusiasts even at countries you don't believe it.

Thank you

Well said!
I lost my nerves here so many times trying to fight against that!

Is there any chance we to see source code here?
Arduino UNO and MINI Pro are here on the bench, waiting me to adapt schematic.
First step is to make better view on it;

The only way I can think of getting the source code is using disassembler (IDA PRO) which will produce C like source code,
which would help if you need to rebuild the source, but it needs to be written from the ground up as the produced code cannot be compiled.

Good schematic drawing by the way.

[Davor]

Too bad there is no source code to go with it.

[bernte_one]

Mr.bernte-one

You ask and provoke people to build one and not ask questions!!!!!!!! Why????

besides any analytics of Schema and code it is often better to rebuild something and see how it works far away from any simulation

While even its designer refuses to show us his device, refuses to clarify some subjects, you ask members to just follow????? You want just "follow us" "like us" without thinking!!!!!

anybody must do it, you cant wait for someone who does it for you
i often doo new Project at first stage of Progress and i often produce something for the garbage - thats Hobby
i burn my fingers with solder iron and hot glue, cut the with pcb saw and drills why? thats fun and hobby

When I asked micheal to make a clear test he said" we test at night and can not record…"
What an amazing reason. Here is night !!!!!!!!!

ok but maybe he has to go to work and has only free time when it is dark outside
at the monet it is same at me i go work all day, and the Weekend belongs my Family i often do Hobby work during 20 - 03 o´clock at night


thank you

i take your text and write the answers between

Yes i thought so. I have IDA for long time.
But i tried avr-objdump and it does the job ... only i can't locate dump file on my hard disk yet!?
Process is invoked from command shell and it runs so fast that i can't see a thing, i only see dump lines "running" fast until it finishes and close cmd.
Must be some flag that i forgot to include in cmd line?
Try this and see if you can catch dump file location; avr-objdump -j .sec1 -d -m avr5 FelezJoo_PI_v3_00.hex

[ivconic]

Got some dumps now;

[eclipse]

The thing is that I can't get pseudocode function to work for this file. I've tested it with Quasar ARM and it was working. Seems CPU dependant.

Dumps can be studied within the program itself, outside and without pseudocode view is nearly useless.

Counting cycles and peek&poking some locations may give some minor changes in code.
Yet it's completely trivial job, there is a danger to lose hair doing that and trying to achieve something!
Sad but true.
I guess we'll depend here on author's good spirit to share... eventually.

Is this real, that you Nokia LCD is in life, or there are only printed sticker foil over it?
Congratulation. Good start - as always from you.
You cannot decompile source code cause in Persian it is written from right to left.

[bernte_one]

we need one language all over the world machine code should all be in english

[Davor]

Bernte, he is just pulling your leg

I'm quite interested to see how the ADC is used here, since Arduino ADC can be forced to sample quite fast, but with resolution reduced to 8bits. You can't have a superb detector with only 8bits, even with averaging lots of samples to achieve some oversampling gain.

Say you have a pulse repetition rate of 8kHz, and you use it for 256 times oversample, the resulting resolution is only 12 bits at 31Hz. You can't have a superior detector with 12 bits at ADC.

But you can learn a lot.

Davor; would it be enough to attach lcd&buttons&extra_few_parts on Arduino and upload the hex file, than connect it to digital scope and see the outputs&inputs?
Before making any progress in this diy it is indeed itchy for me to see the "menus" and options; therefore i did adjustments for Arduino UNO:
