IDX-PRO+VDI

[hamidrt]

Hi
I am interested for this nice project specially about VDI section. Many thanks.
However I have a big problem about PIC micro controller 16F88 or 16F690. Unfortunately in my country, not any of these chips could be found!
Can you suggest me any solution? I think VDI may be reprogrammed with ATMEGA chips that are very common, or at least for another common PIC micro.
Thanks

Who puts OP177 or NE 5534?
Both of them have.

Some ferrite is hard to reject - especially in a ring shape. Try short piece of rod from AM radio.

GEB is for 'tuning out the returns from the soil. - without this set it will false.

PP is pin pointer, this mode is close to non motion, it uses a Rx channel with a zero IF. For getting location fix on target prior to dig.

I think popular is 5534

problem is solved ,bad contact.

Well, what function key PP plays. Upon my only constant sound and no reaction of metal.

Remove ferrite! Tx 0.558 MH, RH 35mh

Tx -33 turns 0,75 ,Rx -265 turns 0.15 /Tx 6.554 kHz Rx 4.604KHz http://youtu.be/RP74P89ACJQ

Tx 1mF Rx - 30nF

The inductance of the coils TX and RX? You have used a different diameter wire. I use wire of 0.20 and 0.60. My inductances are: 34mH for RX and 0,580mH for TX. You have to get these inductances. My capacitor for RX is 36nF, and TX capacitor is 1,22uF.

Try increasing the capacity of the capacitor in parallel with the RX coil. I want more details about your coils and capacitors TX and RX. The videos do not help us much if you do not publish here the parameters of its coils.

This is my detector, but I have a problem setting the GB. Key PP raboti.Pri me how when you turn the detector is silent, and when I move tresh sound constant sound and no reaction to metal.

How to set up GB? switch PP how it works? ТХ 5.25 АС volt (multimer) TX-0.75 33 , RX-0.15 265

Yes, it does. Home build idx, stereo headset, there is no stereo switch on my headset, many thanks.

* A homebuilt IDX or did you buy a manufactured one?
*Mono or stereo headset?
*Does your headset include mono or stereo switch?
If you have a mono headset, then the answer is more obvious - but some speakers are polarity sensitive.
If using a stereo headset there are 3 rings you will see on the end of the cord. The ring closest to the cord is typically common ground (which goes to the grounded end of where the speaker is usually connected). The other two rings can be wired together and that will go to the "hot" end of where the speaker is connected. It is best to put a 200 - 300 OHM resistor in series with this to limit volume and protect your ears.

Does this answer your question?

Hi all,

How to i connect the headphones on the idx?
