SBG- slow motion metal detector

[TurkAlperenebeg]

I know the features are provided by Sash, I was just wondering what kind of coil winding mechanism you developed.
I guess I couldn't explain myself.

[ivconic]

Sure, no problem, but I still don't have a solution.
I'm still thinking about coil 3D drawing and printing..
When I come up with something I'll post it here.
...
As far as coil specs; Sasho already gave the specs:

[TurkAlperenebeg]

Hey, do you have a chance to share the file for the print you made for the iconic coil? I'm thinking of printing it too.
Can you share with us how you do the coil winding part? I'm curious about how you wind your coil.

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?!

[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...

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.

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!

[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]

... 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).

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.

[pechkata]

My PCB has arrived and I am installing it.

Hello, how is the project going...?

[ivconic]

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.

It's boring to be sick.

Приветствую Сашо и желаю тебя
