My New Pi Metal Detector (ATTiny 25)

[bernte_one]

any News on this Project?
did anyone finished it to build a working detector

Jon
Can you tell me what is the sensitivity for object size frag grenade or 0,33 coke can?

This looks good
I have not completed my project yet.

Mickeu
make sure you use the correct TX hex

Helo Jon again

TX and RX is on separate boards connected using goldpins. I just need to add connection for capacitor somwhere near coil.

This is TX section:


PCS's:

Collision on TX PCB is by mask of POT ( i don't have slim one footprint)

Board sizes:

TX 15 mm x 40 mm

RX 15cmm x 51 mm

Also i think to add LF357 inverting signal between diodes and signel reciver, then only 12V without power doubler should be enought

[jon-ecm]

Wow, interisting concept, the power supply looks good, do you have plans on how your going to hook the FET up yet? Or did I miss that in your design?

[mickeu]

Only +12v



Will it work?
Header P3 is only for external pot with power switch.

Hi Jon
the rx board is not completed yet but hopefully soon

[jon-ecm]

Hey, Sorry I'm on here just about every day but didn't even notice these posts.

@mickeu, Like 6666 mentioned, probably the best thing to do about that is email me, Since spammers will get my email if I post it here it's probably best to use the contact forum on my website, www.miymd.com

@target ID is very difficult with any PI machine but the techniques used in this design don't leave much room for target ID except ferrous discrimination when used with a double D or O coil

@6666 How is the project coming along? Got the RX board finished?

Hope than answers your questions.

Jon

[target]

a database lookup table of bad targets ?can, bottletop, ringpull, at all angles in the database lookup table .work on that .

[6666]

Mickeu
send Jon an email and see what he says

[mickeu]

Where i can find source code i thing to make some changes.

Hi Jon
I have sent an email regards the 7805

[jon-ecm]

hi 6666 I sent you a msg a few weeks ago but I'm assuming it didn't come through since I didn't get a reply. I went over the code as well as the schematic (I know you had some questions about the 7805) and everything looks good.

If you have any more questions just let me know I can also give you my number if you want to call which probably works best for me

[6666]

Jon
before I tackle the RX, is there anything I need to know about the code ?

[der_fisherman]

Raison d`etre.....

Gotta love those old cro's, they just keep going!
Glad it's working now!

@Andy
Thanks for the nice words! It's great to have so many smart minds thinking together!

Jon

Its basically why we all love being here......the machines and technology do help a little bit of course......
regards
Andy
