IDX-PRO+VDI

[bgs]

Here the sound is better .With 16 ohm speaker.

after almost 1 year trying to make the idx project work like this I got it, but little sensitivity and I can't discriminate to get 1 coin from 1 real to 20 centimeters, but I'm glad I managed to make it work now. want to improve the sensitivity to be able to reach 1 coin at about 40 centimeters equal to the ones published here on the forum

Hi all,
Can anyone be kind to inform me where can buy a pcb +vdi? Or a kit dyi.
Thanks in advance.

good afternoon I changed the c16 c10 c8 capacitors to the corrector capacitors and now he was getting a cell phone at about 55 centimeters but in 1 coin it is getting at 25 centimeters I think there is still something wrong because the ones I saw working all taking a coin at 40 centimeters

Hello good morning, do not pay attention to the 40 cm for a coin in the air, because the coins are under the sand or the ground, the coils that can hear a coin more than 40 cm in the air, on the ground do not reach 20 cm. When I built the first idx, to compare with the coils built by me, I bought an original Vhite, the coin feels the same in the air at 30 35 cm, but also on the ground it has almost the same distance.

the problem is that the air test is getting 20 centimeters for my idx

because I can't open this file does anyone know what kind of program they have to use

The compressed file is a lay file and contains edoardo's Idx pro pcb.

In my opinion, if you check your idx pcb more carefully you will find other components incorrectly installed. Has the coil been blocked both rx and tx with hot glue?

good afternoon dgm yes i pasted the rx coil and after finding the null point i put the tx too and i managed to improve its null point even more and still the idx is unstable and i cant adjust the sensitivity
the VR3 is for what kind of adjustment

Look at my board which is marked with an arrow when I mounted it I removed the 4148 diodes and put a jumper should I put the diodes back in?

Why did you remove the diodes? If there are in the scheme you have to put them back. I have already said and reiterated to work you have to find the components installed by mistake.

I have 2 different pcb with different mount; what is the correct way?
