Arduino based VDI!

[dfbowers]

I just ordered DISPLAY 16x9 + I2C Module... so no problem for software modifications ecc... Can't wait for that... what a wonderful project!

I think that it should be no difficult matter to implement VCO Audio like Don showed in his videos... a very nice feature I think...very useful!

The only problem I see with the VCO in my experiment was that the output is too binary. The VCO signal would be more useful it conveyed some information on signal intensity or duration.

I'll try to put together schematic and more detailed info.

You have put together some very nice work here. Thanks.

I don't know much about the display you have. If you can control the LCD then you should be able to port it into the program. the lcd functions that are used are: clear, setCursor, print, write(byte). You may not be able to define custom symbols. If you can't then you would have to remove battery icon and "big font" display.
I relay on the Arduino libraries for LCD handling, I just got one that is popular.....

MY Display spec:

(1) Display format : 16 characters ´ 2 lines
(2) Construction : TN/STN LCD panel, Bezel, Zebra and PCB.
(3) Optional Edge/Array LED or EL back-light.
(4) Controller : KS0066U or Equivalent.
(5) 5V single power input. (Special request for 3.3V driving, built-in DC/DC converter.)
(6) Normal / Extended temperature type.
(7) Excellent LC : VOP maintains at 5V for whole temp. range, no need extra temp.
compensation circuit.

Reading here:

• Display 16x2 (KS0066 controller, black & white, no back-light, HD44780 code compatible). First line is working, but both lines are greatly dimmed when displayed at the same time (I think it's a problem in my circuit, not in the library)

I dont know what to do... HD44780 is classic hitachi controller I suppose. It should work with your SW without modifications?

Thanks Daren!

I don't even know about anything of arduino for now. It is just arrived! It is atmega328 version.
I have this display:

ftp://ftp.dca.fee.unicamp.br/pub/doc...eet/AC162D.pdf

AC162D from ampire. It should work with your software and connecting it like your display?

To understand your software (a bit too complex for me) it should be studied like reverse engineering..
Could you explain main functions and how to select menu with only encoder? (no push buttons?)
I would really grateful if you consider to post complete scheme here...i really wanna copy and replicate...sorry to ask too much...

Really genius people in this forum! Pleased of that..

I have not tried it in the field. It should work, the min signal may have to be adjusted up. Because the signal path is the same for TGSL and VDI if the speaker is noisy showing targets the VDI will too. VDI "min signal" is equivalent to "sens" on TGSL.
The Arduino Nano should work. I use Mini Pro with ATmega328 328 has more resources (I think).
The sensitivity is the same as TGSL. It does depend on "min signal" setting. If you lower it VDI will be "jumpy" but very sensitive. In combinatino with audio from TGSL "jumpy" does not matter...

Great Work! I'm going to have to try to duplicate your setup... When the weather outside isn't so nice. I think the Arduino has so much potential, it's cheap, open source, readily available ( almost any Radio Shack in the U.S. has everything you need to get started) and has a large community of users..
Any chance you could post a few videos for reference? (I love watching others succeed in their projects..)

thats really fantasic what you all do here

i am still at beginning with arduino but it has a lot potential for detectormods

another think i thought before was a simple signal meter for all md´s

go on guys the vdi is a big thing

[manny77]

Daren great work you made!

I'm waiting for my arduino nano to arrive. It should can use your sw?

You tested in real soil? Impressions?

Difference in max detection distance from original speaker out of tgsl and max vdi distance?

[Daren]

Yes. This is exactly the one I use... (The page link with arduino that you sent; they also sell the adapter.. just read the page.)

Like this ?, seems to need the driver as well.

[Daren]

Yes. That's it.
You will also need USB to 5V serial to connect it to PC. Just search ebay for "USB to serial TTL arduino"
I had 16x2 I2C LCD and that;s what is coded up. But you should be able to change it to any LCD with not much effort....
The code should work with shifting and non-shifting circuitry. The ADC calibration should to "the right thing" regardless.. (But I have not tried it...)

[6666]

Is this the right board ?
