Pinpointer with discrimination "Cat-FM" on ATMega328P

[useus]

New video on my channel related to PCB design and some things about second revision.
https://youtu.be/67yV1IAClt0

the scheme is a lot modified compared to the previous one, could you send us an image scheme?
who uses atmega328p like me, with this new version maybe it won't work, not having the raw pin atmega328p barebones

Of course yes, but a little bit later, I must completly check It before. All versions will be absolutelly compatible.

great thanks, because certain things are not clear to me, if you can explain the adc and the raw pin, thanks

Of course I will make new video with subtitles which can help you to build very nice pinpointer you've seen before.

Friends,

I find that we have two stable versions 1.5.1 and 1.5.2. Let me explain the global difference between them. Version 1.5.1 has stability tune setting, I mean If your device comes unstable you can try to tune It a little bit with the same sensitivity. Version 1.5.2 has booth sensitivity and stability setting simultaneously but on maximum sensitivity It can be unstable too and If you will try to Improve stability you will reduce sensitivity. If you will ask me I will answere I'll prefer 1.5.1
You can try both one and choose the one you like.

Dont forget that our planet has an electromagnetic field which can sometimes lead to Instability, so In case of that you can just recalibrate your device.

"CAT-FM" 1.5.1 release:

"CAT-FM" 1.5.2 stable:

i tried 1.5.2, it actually sounds a lot without target, i went back to version 1.5.1 which seems to work better

I wrote about the difference between them, 1.5.1 I prefer because I like tune device on maximum sensitivity and I don't need reduce sensitivity at all.

The topic Is over?

The topic Is over?

you should be the one to carry on the discussion, we have made proposals and questions, we are waiting for answers, especially as regards the pcb v2 you have published

Hi, ok, Arduino Pro MINI development board has linear regulator on board, so In my new design there It's not nesasary to use 7805 regulator. "RAW" Input Is Arduino Pro MINI linear regulator Input and when we apply 5-16V to It on the VCC line we will see +5V or +3.3V.

ADC - This input I'm using to control charge of "6F22" supply battery.

Friends, repeat your proposals and questions please.

i got it thanks, so the pcb i built for atmega328p barebones is not necessary to modify it, i was interested to know this. I thought you used the adc as a sort of voltage reference, I was wrong

From 6F22 battery our voltage applyed to resistive divider and then, voltage from divider goes to ADC Input to control battery charge), I ordered V2 board from JLCPCB and after testing I will make full video with table and ground tests.

i will implement it in a new pcb version to keep it updated
is the battery charge level signaled by a buzzer or LED?

[useus]

Friends, repeat your proposals and questions please.

the three degrees of sensitivity can be improved, at the moment the targets are too close depending on the sensitivity level.


it would be good for example: 1 euro coin
-level 1 1,5cm
-level 2 3 cm
-level 3 maximum detection

It will be sound + LED
