IDX-PRO+VDI

Being a geezer doing surface mount electronics is not by capability. I tried it and I don't have the skill to solder such small areas. My old eyeballs don't see that good.Do you have a non-surface mount version of the circuit board ?

You are not alone with the eye sight thing. Poor vision has taken a lot of the enjoyment out of electronics for me in recent years. I really have to be motivated to build something now.

I have used magnifying lenses of various type with some success but it is a hassle. I have a couple of very small closed circuit television cameras that I am going to try next. If I find a combination that works, I will post it.

I had a bit of a look at those atmega32 chips, it seems the smd's have 4 extra pins that the dip's dont
so maybe we will have to borrow hugo's magnifier

@goldfinder:
Do you ever try with a magnifier ?

looks like surface mount ?

That Vbox looks nice

[shansov]

voltage capacitors, which is used in the scheme IDX-PRO ?

[silverdog]

V-Box2 looks very interesting, which detector was it originally developed for ?
Have you got it working on the IDX ?

It would certainly be a major challange looking at the pcb

Hello what model LCD I use? .

Any standard 16 x 2 character LCD

It like as you have problem with MCP602 or around it.

Hello ApBerg,

VDI work does not depend on the TX frequency of the MD.
Is essential phase angle between x & y channels .

Best regards.

Hi,
I'm trying to connect VDI to my poor 1225X clone.

http://www.geotech1.com/forums/attachment.php?attachmentid=1637&stc=1&d=1170356731

I made some testing and it was showing #45 on screen with Cu and Fe
Y was connected to TLC27M4 pin 14 near DISC-potentiometer
X was connected to TLC27M4 pin 1 near DISC-potentiometer
+ and gnd from MD 9V battery

Any ideas where to connect X & Y???

Thank you and Eduardo Silverdog
It works!. The 20 K pot set at one end, to "0" volts.
Thank you very much to all who made this project possible
Regards, Jose

Hello Forum
Someone can tell me if the PIC16F88, can be replaced by the PIC16F88 I / P?
Complete assembly of the VDI with PIC16F88 I / P, but the screen does not light.
thanks

Look at the contrast potentiometer (RT1-20K). To regulate it to the right or left.

[silverdog]

PIC16F88 I/P is what I supply and works for me on my IDX

Check contrast pot and LCD connections
