Arduino Nano PI Main Discussion

[Xtrem]

The drivers for the 4066 are not necessary, if you handle only the positive part of the signal (0 to +5V)

Have you made and tested these changes on the original circuit?

Yes

plus changes on the sound.

This is a nice project , especially for learning and education, but let me make some changes to the
circuit.

Those are good distances. Guessing this is 'air' tests.

Correct, those are air test results. However, unlike a VLF, PI detectors show little or no difference between air and ground tests. In fact, some people claim (in certain ground conditions) that PI detectors demonstrate a greater depth when the target is buried in the ground matrix.

Results with 9" (230mm) diameter coil.

What depths on the coils?

George are those video links on page 1 supposed to be set up as they are now ?
if you click on

Pt1 you get Pt4
Pt2 you get Pt2
Pt3 you get video unavailable
Pt4 you get Pt4

Well, I managed to completely cock that up!
Note to self: "Don't make updates late at night."

The links have been replaced by the playlist supplied by surfdetector.

Ordered my board from Andy tonight.

So do I. I am a fan of the use of Arduino modules.

I've added links to your youtube videos in post #1.

What are you thinking of doing with the audio?

No set plans as of yet. I have been playing with some VCO synth circuits based on the AS3340 and the CD4046 to get something more pleasing to my ear. I had been using one of my Crossbow boards but now the Nano is in my vise so I will continue to tinker.

Thanks for posting the links.

The Nano was a fun project and I shall keep it in the vise on my bench for the time being. I want to play with the audio. Good to hear that you have seen some of the videos.
