Arduino based VDI!

[gtdavid]

Also what is the maximum voltage observed on the u3 outputs for the idx?
And how are others getting a depth reading ?
Thanks.

Come on folk I interested in the answer on how these preform

In the main IDX thread someone did say the original VDI was good to between 50% to 75% of maximum depth

[gtdavid]

Are your VDI's depth specific ?
My vdi results change as the item been detected is moved up and down giving inconsistent vdi results..

Interesting work GTDavid

Hello all,
I have been playing also but I am using a stm32f1 micro and 2 displays.
I am going to controll my pots with the micro with digital pots.
I also would like to explore some sort of auto ground tracking also.
A bit hacked together atm but I will get there.
Thanks for the kick start by shareing your code.

I've been playing with a nice display for the arduino. SainSmart 1602. Paralell port connection, uses A0 and resistor ladder for keypad. Really quite cheap on ebay. Got an arduino clone for 3.96 http://www.ebay.com/itm/311155383820 and http://www.ebay.com/itm/390798719366 Now I just have to do the analog part.

i know this from first Projects i do in one rush
soldered parts all night Long, testing epoxi glues, enclosures, electronic parts and waste lot of Money

important is to make a concept of what you do next
make notices on paper, see what could work or what is waste of time and Money
it is not clever to do all alone, often you can by ready parts or someone else has a better idea
it is good to talk about before you begin the next practical work

if you start let us know

der Fisherman: "How good is it with regards to depth? Both air and ground?"

With that small coil depth is not very impressive. But i build it for "Seperation". Seperation is best without VDI-Tones. The VDI is too slow for extreme situations. The best results made with the original modes of TGSL (Twotone mode "On" will slow down seperation too). Best results are in discrimination one tone mode. I tested a mod from this forum wich is very good for seperation and swing speed, but it dont works good with the twotone mod. For seperation and swing speed the mod from Geotech-Forum works best with the original circuit.

@Bernte_one: yes....the next project will be started soon....but for the first time ive been tired from the last project;-). It is a lot of work and time....But i think i cant wait too long to start the next mission;-)

Mission accomplished;-)! Thanks to all the guys who helped me (especially Daren). Im very proud of my new detector;-):

Well done looks impressive. .

next Project for you, pi detector with vdi

Very good Video, liked the music too.

Plus the detector is very impressive in both looks and performance with different metals.

How good is it with regards to depth? Both air and ground?

Many thanks for sharing.

[QUOTE=dfbowers;153092]I actually finished my IDX + Arduino UNO project. Below is the link for what the code in the previous post actually does. Neat thing is, you can program it to ID anything you want if you know the VDI range.

hello fellow, I liked the clip very good job! Can I ask you a favor? I will be very happy if you help me with one such file HEX. that they displayed different types of metal foil, zinc, silver, gold ........... I wish you success in the future.

While waiting for parts from china I have been designing the plate in sprint layout. I would like someone to check if the plate is correct. Later I'll upload the file for everyone, now I need to know if everything is correct.

Seems fine.
