SBG- slow motion metal detector

[ivconic]

Unbelievable, but it finally happened!
The PCB from China has arrived!
A colleague sent it to me a long time ago, but due to a bad choice of sending method; pcb traveled too long!
So much time has passed that I have completely gone out of focus and topic.
It will take me a few days to pull myself together and get back to this thread.
I'll let you know here when I make some progress.

My PCB has arrived and I am installing it.

my suggestion avoid problems - sold to PCB or use золотые панельки для микросхем goldplated sockets.


somebody download Саша видео?

I'm currently in the trial and error phase; I'll try it out and see. Thanks for your advice.

It's boring to be sick.

Приветствую Сашо и желаю тебя

I started soldering the components.
And like Murphy's Law ... I'm always missing some trivial components!
I will have to order them and wait a few days.

Hello, how is the project going...?

Hello, how is the project going...?

I'm currently missing a few final materials; I'll get them, make the final touches, and share my test video with you.

... In several areas (U3, U4, U5), soldering in sockets would be difficult...

Not at all...
The 2D/3D drawing on the JLPcb website sometimes does not reflect reality.
I have a lot of experience with those web displays so I wasn't too worried about what would happen on a real pcb.
...
Damn capacitors!
I always miss them.
I have "tons" in boxes in the attic... but I don't feel like searching and digging, because it's all unorganized and unclassified.
It's easier to buy new ones from the BOM list (which I didn't make because I'm lazy).

[ivconic]

Well...
what do you know...
I thought; who will now wait for the components, it will take a few days for them to be ordered and arrive at the address.
I went to the attic and found everything I needed.
The PCB is finished, but I'm quite exhausted, because I'm no longer in shape.
Now there's a short break so I can devote myself to coil.

[ivconic]

Without any adjustment, without turning the potentiometer, as I soldered everything - I immediately turned on the voltage.
Works like a charm from the first switch on.
Now I am definitely motivated to devote myself to coil making.
This is very promising!
Well done Sasho!
A phenomenal project!

And now we are waiting for the results in real soil. The tests in the air are good - as ivconic said - every proposal must show 3 things: a schematic, a PCB design and a video in real conditions to be properly evaluated.

[ivconic]

That's right.
However, now comes the most difficult part: designing the box, making the coil... phew!
I haven't DIY coils in ten years... I avoid that boredom, I mostly used stock coils.
But this time I'll have to DIY the coil anyway...

[ivconic]

My 3D printer has a working volume of 220x220x250mm. But in practice I always use 200x200 bed area.
Ideally would be to 3D print the "OO" coil housing...200x200mm.
But how do I know the exact overlap area in advance?
For precise balance.
Maybe Aziz could help with his magic here?!
