Thank you very much
for sharing
I'm waiting anxiously for you
you did a great job.

Hi Everyone,

I'm building a TGSL and I plan on adding one of the VDIs in this thread. I like the idea of seeing what type of metal/object, I was thinking of editing the code a bit so that when you go over something like iron or gold that it'll display the words for it as well.

Does anybody have a list of ID/Phase/VDI numbers ranges that are produced when using TGSL for different metals/objects?

Thanks!

dude, that's great.I want to do it .please read more.Thank you.

i'm very interresting.

is it you? https://www.youtube.com/watch?v=ikg0VJCtUzE

[andon80]

dude, that's really cool . can you open the schema

Hello


I'm still working on this project because it's quite complicated and some things do not want to work the right files will be available soon on Github.

Hello friends


Here are the complete files for the ESP32 Metal Detector. It's just the first version so some features still do not work properly. I would love to find someone who would also start working on refining the detector and helping to improve it.

Is there a schematic ?

[Marchel]

Yes Eagle files https://github.com/folny/ESP32_Metal...er/Eagle8_file

[6666]

Do you have a picture file ?, not everybody is going to have Eagle8 program.

Maybe a PDF would be good.

You can also download free version of eagle from Autodesk which will be fine for viewing.

Cheers

Hey Everyone,

I decided to build the VDI that Daren has made, I like the extra options that it offers. However I'm not quite sure what the MCP602 is supposed do. For the MD_V13 there is an included read me file that doesn't mention that the MCP602 is required, but the included schematic shows the MCP602 in there.

Daren mentions MCP602 in post #69 http://www.geotech1.com/forums/showt...684#post193684

I use LM358 single-side powered with 0 and 5V. It swings 0-4 on output. Circuit is like the one for IDX-VDI minus balancing resistors (R9, RT2 i think).
Seems to work fine.
Arduino Mini Pro 16MHz, 5V with LCD (dimmed with 1K) and opamp takes 12V/25mA. Arduino is powered using TGSL's 12V and it suppliers 5V for the opamp (mini has a 5v regulator). I'll swap in MCP602 when it comes from china; it should have 0-5V output swing.

I ordered a few MCP602's because I want to build the VDI correctly but, What specifically does MCP602 do in his VDI?

Thanks!

Because Arduino can read 0-5V and input is -6 up to 8V?

Also batery reading is voltage divider to rescale 0- >12V to 0-5V.

Thanks Hyena! That helps give some explanation.

Here is my new Arduino vdi project with small 128x64 display. Implemented bargraph and custom font's. Machine on the photo is IDX with 12.5 inch coil. Soon i will upload short video...
