Mirage PI Project, anyone interested?

[SVEN1]

Replied to your email regarding CrossBow PCB's.
I do have a limited supply of the Mirage PCB's.

What do I need to do to purchase two of them?
Form of payment?

What would the total be for:
1 PCB and electronic component parts and 1 additional pcb shipped to Ca?

[SVEN1]

I replied to your email regarding the Mirage. Would need a postal code to figure shipping which varies widely within Canada

Please Seven What are the dimensions of Control Box[ATTACH]38014[/ATTACH] And I did not find in the shipment box on this resistance variable keys[ATTACH]38015[/ATTACH]

Hey hammerhead,

that layout just happens to be one of my builds of Svens mirage that I did last year.
here is the layout with overlays of the controls from my post earlier in the thread.
The freq control is a ten turn pot from china and works very well.

Originally I used a single turn pot for the external frequency control. But, found many have a tuff time fine tuning the frequency.
So I switched over to a 10 turn pot but, needed one that was compact. The standard 10 turn Bourns had just too big of a body to fit into my smaller control boxes.
Then I found the in the above pictured pot on ebay. Bought a few to test out, they work excellent. So I posted about them and those that followed suit and bought one, really like them.

They are made in China. Price is cheap. They only come in 10K. At one point in time there were about 10 sellers or more selling these on ebay. Shipments to Canada from China used to arrive in 15 days, they now take an average of 15-30.
Just a note, if you buy them from different sellers, you may find 1 and 3 pin-outs are reversed.

A good alternative if you need a different value pot is one like this http://www.ebay.com/itm/10K-Ohm-3590...QAAOSwZVlXlbEI

i think you just wiped your hard drive

Not really!
Hard disk media is protected by metal case, a "Faraday cage".
...
BTW i would expect somewhat better distances with that coil on video.

When properly calibrated distance is much greater. Plus the poster didn't have an audible threshold tic. Without a threshold tic there is less depth

A 5" coil I made originally would get about 1 to 1.5" less than the 7" coil below.

Last noticeable, faint signal change

Using the 10.5" search coil
Fish scale(1/2 dime)----------9"
Sterling ring---------------------10"
10k ladies ring------------------11"
14kt man's wedding band---14"

Using the 7" search coil
Fish scale(1/2 dime)----------7-8"
Sterling ring----------------------7-8"
10k ladies ring-------------------7-8"
14kt man's wedding band---10-11"

Seven hello What is your comment on the picture

Seven hello What is your comment on the picture

The image states "All Coil 300mH". That should be "300uH".

Your correct 300uh, I do not know where or who made up that picture.

Salam Hammerhead, great that you are still around! How it is going with your arduino board detector?

I have an interesting youtube video for you:

Sunken Ancient City of Heracleion

Because many old treasures of Alexandria are meanwhile 5 kilometers out on
the sea and under water - because of earthquakes and ancient Nile-floods.
