Pinpointer with discrimination "Cat-FM" on ATMega328P

[Ruben2000]

Hi all, I ended up building a 'High Voltage Rescue Shield' that connects to the Arduino Uno. Glad I did because it rescued 4 x ATmega328P-PU's for me so I didn't have to buy anymore. They all programmed successfully after that. If anyone wants a copy of the Sprint layout I re-drew for it I'll post it here. I built my coil for the CAT FM V1.2 last night so I'll be assembling it all later now I have working ATmega's. Thanks again for the project Void118. Regards, Marty.

Hi Marty.
How did you get your ATmega 328 back?
Could you help me with that? because I have a 328 locked for a long time and I don't know how to unlock it.

another tip is if possible to improve stability, after detection, when the object is moved away, it is often necessary to recalibrate because it continues to sound

(I make you fatigued LOL)

Sometimes I've seen It, try to remove all Iron objects from sensor)

Hiya Ruben. I built a 'High Voltage Rescue Shield'. It will unbrick your ATmega328P chips. If you send me your email I can post you the files to build it because the folder is 2.78mb so I think it is too big to post on here. Regards, Marty.

it does me even with the object closest to 50cm. I'll do a test away from home, maybe by adjusting the sensitivity I solve.

Yes, you are right, unfortunantely an electromagnetic wawes aroud us can bring frequency unstable and we can solve It by decrease sensitivity or recalibrate device only.
Here Is new, Improved version v1.5.2, try It please:

Hi Marty, I sent you my email

Thank you void118 for this great contribution.
I have not yet built a pinpointer.
This project looks very easy to build, I am putting the pieces together to build it, I think I will use the USEUS PCB.
Thank you very much for this project !!!!

1.5.1 and 1.5.2 firmware differences

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.
