ok I'll do it this way you taught me but a question to make this measurement the coils have to be connected to idx and with it working?
I'm from Brazil Rio Grande South

Hi the coil does not nulling like that, with the oscilloscope it is better, but you can also easily attach the rx coil to a tablet with hot glue, then with a digital meter with AC measurement on 2 volt scale and then 200 mv , connected on the wires of the RX, then position the TX by moving slowly until you find the lowest voltage around 8 - 10 mv. Where are you from?

I'm away from home now when I get home I'll make a video of it working and I'll try to post it here on the forum

[Uiliam950]

but as I've already mentioned when I turn it on, it beeps then it bangs and I can't adjust it at all, I increase the sensitivity but it's as if it hadn't increased

As for the DD coil you built it seems to me that everything is ok, the only thing is nulling I can ask you how how did you do the nulling and with which equipment?
In order to help you I need to have this information, let me know.

good morning as I don't have an oscilloscope to find the null point of the coil, I'm trying with an object until I reach the greatest distance

I used the coil dd rx 33nf the capacitor and tx capacitor 1uf [ATTACH] 56160 [/ ATTACH]I used the coil dd rx 33nf the capacitor and tx capacitor 1uf

Hi Good evening, I took a look at your idx, and I found that you used surplus components, let me know what kind of coil you used DD o concentric.

[Uiliam950]

my rx coil has 270 turns 0.15 wire and tx has 35 turns 0.60

Sorry Mr. Uiliam950 but if you need help with your idx you need to post clear pcb photos and let me know which coil you used, is it original White or self-built?

[Uiliam950]

Hi Mr. Uiliam950 you can post pictures of your pcb on both sides?

good afternoon friend sorry for the delay to answer so I put all the new integrated circuits and it gave sign of life but it gets a crackling noise similar to the Polish pi but you can notice that it is detecting but very little sensitivity like a cell phone it is capitating at a distance of 18 centimeters
