Can pinpointer detecting thin chain?

[Nezocas]

Hi Nupi,

It still doesnt work
I made a few changes to component placement mo make it really small
I made a drawing of my connections but I think they are all good
Also tried your tuning chart. but no sucess

Hello Nupi. Thank you very much for your reply. Yes, perhaps C2 is very small, I will change it.
I will try to reproduce the coil as close as possible to the original design, to avoid problems later.

I will keep you abreast of my progress.

Regards,

Fabian

Tuurlijk, geen probleem.

Groet,

Sure, no problem.

這似乎是一個國際性的俱樂部在這裡！




它看起來不錯，就像你說的帶有個人色彩。它給了我滿意
我一直在賽道上幾個小時後。
看到別人享受它，以建立電路。


這是很好的，如果你不使用原來的線圈值與C2的值進行試驗。
約22-33NF值可以像2你try.Parallel連接，15 NF效果很好


我認為沒有錯誤在PCB
但我說的話，因為我經常出問題，你應該沒有任何附加價值。


唯一我注意到的是C2的在PCB的大小。這似乎是小的，我想。


It seems an international club here!!


It looks good, as you say with a personal touch. It gives me satisfaction
after many hours I've been working on the circuit.
To see that others enjoy it in order to build the circuit.


It's good to experiment with the value of C2 if you not using the original coil value.
A value around 22-33nF can you try. Parallel connection like 2, 15 nf works well.


I think there are no errors in the PCB
but you should attach no value what I say because I regularly go wrong.


The only what I noticed is the size of C2 on the pcb. It seems be to small, I think.

nupi

Hello Nupi. Congratulations for your great design, which soon begin to assemble. I like to give my personal touch to the PCB I do, so I made my own design based on that of Hadrianus, but according to the original diagram drawn by you.

I hope no errors!

Hola Fabian, si no te inporta lo miro mañana tranquilamente.
saludos.

Ja, je hebt het goed veranderd .
Yes, you've changed it well.

ps. your Dutch is very good!!!

Hi, nakky!
I just had a short view on the second pcb and one thing jumped into my eye:
The two spindle trimmers will work as fixed resistors in that configuration. Connect the middle pin to one of the outer pins at each trimmer.

Thank you for participating in this thread. You're right.

Sorry, nakky, I've overlooked.

Thanks NUPi ,
Yes later.

Sorry,change it. Nakky 29444

Hi, Nakky
Does not matter, I probably make more mistakes than you. In that aspect, I am a super nerd.
I think it's okay now, well-done.
I want you to say that there is no signal from pin 10 of IC 4024. But You can take it from pin 12.


Are you going to build the circuit?

[nakky]

It looks nice and clean and pompact.
But I see some mistakes.
I have no time no, but over the course of the day or tomorrow I more time.
Maybe there's someone else who wants to chek the circuit.
Few points: Resistor R5 - 1M in series with C4 - 1.8 must connect from pin1 to pin 5
of the IC-4024.
On pin 10 is no signal.
R1 must be a potentiometer. It is the adjustment of the sensitivity.

good luck.
