KT, I saw a mod for audio for Delta pulse "koljaj". Have you any more info on it's implementation.

[kt315]

DB

i did not checked this mod, do not have detailed info. koliaj wrote it gives more stability. in my opinion DP works perfectly
and stably, in a case you did all right.

This?

Yes, exactly that version. I have problem, board is not dead, but missing some voltages.
Also, thanks kt315 for those photos.

嘿家伙，到目前为止效果最好（深度）是多少？电路和线圈的参数是什么？
我的探测器工作并不完美，需要帮助和您的测试结果，以供参考。

Nice board the original drowing is made by kt315
I was looking for vu meter and most that I find are expensive anybody know where I can find good prices

[waltr]

How inexpensive??
I can find many analog VU meters for under 10USD.
Aliexpress, ebay, etc.

A VU meter is simply a 500uA meter. So possible other meters can be used.

[kt315]

50 micro or 100 micro Ampere. NOT 500.
