Arduino metal detector?

[Point]

i dont want to open a new tread about it so i post it here
I have tryed to rebuild the PI Detector from dc42 https://github.com/dc42/arduino but i dont get it to work... the code stop at line 121.
coils shold be arround 7.8kHz with 1.2 uF Cap. I have measured the coils with a selfbuild LC meter tolerance arround +/- 5% and double average sampling (5k samples) 328-340uH each.
maybe anyone got a idea what is going wrong?
Edit: i have checked the breadboard double and trible and is everthing fine so far.

with schematic do you have use on the second YT links?

[CDI]

and now? did you finish your pcb layout?


best regards

Nothing about our arduino md.

Will upload it tomorrow. I already found one problem though. The mosfet pads are wrong. Must be bigger.

thats no Problem four eyes see more than two
so if you like post it

[captainart3000]

can you please upload the layout file for you board
maybe black White Image and silkscreen?

thx

I havent tested it yet.

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

I didnt take my Gen2 out of the box yet too but I tried compiling with Gen2 board selected. Sketch doesnt want to compile. Says something about Deconstruct and Highlighting Timer1 and all the stuff above. That was the IB one. I havent tried PI yet. PI is much simpler and should work.

Hey captainart,
I haven't had a chance to play yet, It will be some time before I can. Not home for a while yet.
The Gen2 is supposed to be pin out and arduino ready!
I haven't even got to power mine up yet.
You should be able to just plug in your shield and load the Uno 3 code. (They Say)
Make sure you Use the proper voltage jumper on the Gen2 for your shield though.

Best Of Luck

Im running it on UNO and Nano. Just got Galileo gen2 board. Any luck porting the code to Galileo? I'm having problems with timers. Any help porting it to Galileo would be great!!!!

very good, nice experiments, I like them both: the PI is very simple but effective and the IB design has an interesting code..

I understand that you are proud of your project, but please do not spam the forums with multiple posts on the same subject.

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

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.
