You could just design the TX circuit to run on 7V and then the boost is not needed. I have design PI circuits as low as 3V.

Don't worry about the MT3608, because it works at 1.5 Mhz, and it won't be a problem if we filter its output. If metal separation is expected for PI, TX current and voltage must be fixed, otherwise the device metal separation always upsets the user.

...When I draw and print the final circuit PCB, I will share the videos you want.

So you don't have ready device from the photos you posted???
I got the impression that you have that device along with Android apk, and you can record short video with it...
Obviously some missunderstanings here...

I had this PCB made last year, I would like to remake its digital structure using its analog structure with your suggestions. of course for this site

The detector on this PCB does not have a screen, it is directly used with an android mobile phone via bluetooth.

Yes you said you had it, don't you have it no more?
In case you have it; connect it to phone and record a short video of simple detection and behavior...

I have an android apk for this pcb that I wrote for testing purposes, I haven't written it yet because I'm going to design it new. It's not that hard to write it...
There is nothing visual in the apk for testing purposes, when the bluetooth connection is provided, it reflects the data from the card to the screen and shows the values, like an LCD screen.

We will write the apk for the PCB we will design after the device is running, he is in no hurry.

"...hi, since no one has received a suggestion, I have this analog structure for digital;
a- I added 1 x 16x2 lcd
b- I added 3 buttons
c- I added an hc05 bluetooth module for future use for android or PC (I will activate it when the project progresses)
d- it is the sound layer that upsets me. for two audio outputs, the atmega328 is a bit old architecture, there are 3 timers inside. I couldn't activate timer0 because timer0 is used for millis() and delay, I couldn't use timer1 because timer1 is used for spi, only timer2 remains, I couldn't use it in the sound stage because I used it for firing the mosfet and timing in TX. i wish i could use a more powerful MCU sure it would be easier. But for members I have to use atmega328..."

a - No problem, piece of cake
b - 5 is better than 3, if you explain the exact functions of those 3 buttons; I might understsand better the concept.
c - No problem, piece of cake
d - Don't worry too much about the architecture of Atmega, just clearly describe the processes you want the code to do.
Changing a timer will only spoil some of the Cpp functions. Well-written code for a PI detector cannot rely on code written only in Cpp. You don't need many of these functions at all.
Don't waste time on things that haven't happened yet. Instead, describe it clearly in the form of a descriptive algorithm; all the processes you want to happen in the code.
Direct port/pin manipulation is 14 times faster than a similar function written in Cpp.
All necessary timings will be done with the help of a timer(s).
Outside the main code, independent and having the highest priority.
Everything else comes later.
Is it possible to finally get a better resolution schematic? And possibly Sprint files of already existing pcb from posted photos?
This is the last time I asked about it.

When I did my version of the Hammer Head II, I used a header to connect the processor. This allowed using any processor for very easy upgrades.

Why do you 'Have' to use the very old atmega328? Which members?

I think no one is responding to your thread due to this is a simple an old design. Good as a beginner's project but not much else.

The Arduino Nano project is much more up to date.

And the Voodoo has very interesting concepts.

In a PI detector a Must Have feature in Ground Balance.

I agree that this project is a very simple project. But rest assured, I have a lot to learn from you and you from me.
I would like to use Arm, esp etc. mcu's, but members may have problems in discarding their hexes. In falezjo, I used atmega328p because members know how to load atmega hex easily.

There are points that I do not know or can not overcome, I am an amateur. My main job is not electronics, but I have been busy with treasure devices for 15 years. You will understand that these devices are fun, have fun...

This is the last time I asked about it.

I hastily drew the schematic and am attaching it here. I also drew the PCB according to the diagram. I am using sprint layout, I am attaching that file as well. If you don't mind, I'll build the PCB next. In the code part, I plan to share the oscilloscope images step by step.

The menu is simple with 3 buttons;
1. menu button: make ground balance if pressed short, settings menu with long press
2. Up button: If not entered in the settings menu, increase the sensitivity, and in the settings menu, increase the relevant setting.
3. down button: decrease the sensitivity if it is not in the settings menu, and decrease the relevant setting in the settings menu.

That's what I wanted, THANKS!
OK, now give me some time to analyze that and see...
I will inform you, once I form a opinion on this.

Did you download the proteus and sprint layout files?

[ivconic]

Yes!
But I didn't opened them yet.
In a few minutes I will.

[ivconic]

Dang!



Is it possible You to save it in earlier version?
I am not sure Proteus can do that... must check.

[ivconic]

This one is alright!
