Arduino metal detector?

[joop]

Anyone tried using an Arduino board to build a metal detector? Thinking about a pulse-induction type detector, like Andy's Chance detector.

Would be nice as an open source project, with the code to be downloaded and modified to your needs. Maybe even with a custom arduino shield.

I think there's a project or two in the forum. Otherwise, you may find some interesting analog work to keep your soldering skills from getting rusty.

I have thought about starting a project also. Although I doubt I will be using Arduino script, currently more comfortable with C.

Anyways, I'm currently too busy with other projects, work and life.

Do a forum search for Jon-ecm

Thanks Mario, I will have a look.

Nice job, can u post schematic?

Instead of the rubbish 'music', a spoken commentary explaining what was being demonstrated would have been more helpful.

I am laying out schematic in eagle at the moment. Will post it soon. Code also.

I would love to see something new and interesting

Hi everyone,
I was thinking about this topic for a while now (Arduino or Raspberry Pi based PI detector) and the idea is a good one.
I'd like to see captainart3000 schematic, seems nice PI detector, good work man..

The idea is good cause one gets the pros of having a programmable MCU and little extra electronics (e.g. serial communication things) all there on the board, and can drive a PI in the various sections say tx, rx and integration/switches required.. as in other projects like clone PI (that uses AVR atmega8, and arduino is really close as hardware e.g. like some use the atmega328p).
That said, the problems: arduino is a bit noisy, so shielding it can be important and , second, that the analog electronics must be with a very good fast and low noise front-end amplifier and good low drifting electronics.. but all stuff we can do for cheap.

It's a very interesting idea and deserves, to me, more interest by the forum.
I'd like also to see/know about improvements in last years in discriminating PIs using commercial MCUs..

Kind regards to everyone and happy new year
Max

Hi Captainart3000,
I would love to see your schematic.
I would like to try this on a Galileo board as well as the Uno.
Thanks for the good work.
digit!

Schematic where are you?

[captainart3000]

The PI one I built based on schematic from Alex.
Here is the link to Schematic and sketch: http://alex---1967.narod.ru/PI_metal...arduino_u.html
The other one IB based on schematic from dc42 https://github.com/dc42/arduino/tree.../MetalDetector added more hardware and added some code. I will probably make it public a little later.

Here is the picture of the prototype board shield for arduino nano.

Thank you for removing the right ones! I was just lost on where to put it.
