Arduino based VDI!

Can I substitute mcp602 for lm358?

[inductor]

hello, seems i am a bit late to this party. very interested in this project. but it seem the links and stuff are not working any more

i have a whites coinmaster 6000 that i would like to experiment with using arduino and well into the electronics metal detector hobby builds

these videos show exactly what i would like to learn more about, but there is not much info on how to get started. thanks

i give nothing on air test
ist just for first function test and no more

50cm for one 1€, yes no Problem, give more power on tx and you will receive your 50cm
but in real ground you get more falsing

if you pickup a 1€ coin at 20cm in real ground while discriminating a screwdriver or a big nail the detector works good, if you get 30cm it is top

Agreed

I used the machine for a couple of years. Large copper coins 10" in the ground is pushing its limit. Small silver under 7" I didn't use enough discrimination to fully knock out iron but listen to the break up of the sound through quality headphones. Otherwise sensitivity tiny silver on its edge is nearly halved

Made several coils. Having a coil that runs quite in the field is for more important than out and out depth. Otherwise you will miss all those faint signals.

i got Maxima 1500 Coil now and first test is ok it detect silver no problem...
also disc pot works well and sensitive.

and 1Euro(1 Turkish Lira) 35cm noisy... 28-30cm good clear. i will see VDI test tonight.

how can i improve distance more? 1 euro must be 50cm for this coil ? .....

i tested also ground balace POT possibilities and NO SILVER again. tomorrow i will have another coil Maxima 1500 and we will see...

Can anyone test that IDX PRO arduino VDI can show VDI number in how many CM ? i need data for 1 euro for exampe 30cm detect distance and 20cm VDI result distance...

thanks

As i remember, my was between 85 to 90, but also depend on how you set disc pot.

Hello,

i was trying to Arduino & IDX PRO VDI but my IDX PRO (IDX final schmatic) doesnt see Silver ? disc pot is working i can erase all metals but in any position of disc Pot it doesnt see silver and not stable VDI also i can see difference 1 euro and beer tab on arduino but what can be wrong on my circuit or Coil ?

thanks

If you cannot detect silver that could mean that your phasing is a little off. The way I build my coils, there is a null spot while ground balancing to ferrite. One side of the ground balance, silver is not detectable.

Can be wrong ground adjust or bad rx tank. Try on TX to put 330N and for RX 10N.

Thank you Mr. Daren.

Encoder arduino side:
//Rotary Encoder with a push button
//GND -> encoder pin C
//GND -> encoder button pin 1
#define PIN_ENC1 2 //Arduino 2 -> encoder pin A
#define PIN_ENC2 3 //Arduino 3 -> encoder pin B
#define PIN_EBTN 4 //Arduino 4 -> encoder button pin 0

Hi Hello everyone, I wanted to ask the gurus of this Forum, how can i connect an encoder to Mr. Daren TGSL project with VDI MD_04 in order to access the menu, as seen in the video (http://youtu.be/dh_BKukrgfk) . Thanks, to anyone who can help me.

Here https://bitbucket.org/fmalpartida/ne...tal/downloads/ was taken the library NewliquidCrystal_1.3.4.zip

https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads/NewliquidCrystal_1.3.4.zip

And it all worked.
Only I renamed the folder after installing zip in LiquidCrystal_I2C

Hi, the X-Y output on the IDX PRO is the LF347 pin 1-14 or 7-8. For me the 7-8 works the best and the 1-14 not so.
Vlamvers you have the same problem as dgm had ask him!
