Serbian "Most Wanted"

[ivconic]

I can't promise soon to record video. Friend with camera is 60km away from me and right now roads are under heavy blizzard, so trafic is interrupted frequently. It is a question of time where he will be able to visit me.
Week...two...or more? I can't tell...

Hi,
There are some differences.Your coil is 0.9mH;2,1ohms/14,72mH;30,6ohms.
And RH coil is 0.9mH;3,9ohms/15,83mH;40,6ohms.
What can you suggest me to try,so I can compensate resistance difference?
Thank.
p.s.I see that there are bad traffic conditions.No matter I can wait.

I don't have a clue?
Use some calculator and calculate possible cap values at TX and RX...
Right now i don't have time to do that, must go now...

You made the topic so much about the detector, which is so simple, and which is all known. My first Gold Rover as it so then I called before I did 5godina. Set a pattern for you two tons, which I did 3 years ago and which is 100 percent accurate.http://www.geotech1.com/forums/image...ilies/wink.gif

Error .... I'm sorry, ZD2V7 is oriented wrong!

Hi,Magma!I think there is another one mistake in this pcb.At the pot "SIN" middle pin,which is "+" must be connected to right pin ,where must go "+" too..

Thanks, but I ignored it, only the exact schedule
components.

Thank you neighbor, I forgot about this upgrade, it's been a long time since then.

Ok...i skimly searched through my HUGE pile of scraped pcb's and founded this one with audio extension included.

Since my camera is to bad i also discovered EXCELLENT method to take so so sharp photo in present conditions in my living room...
...
Later on i might find a proper schematic too..need to search trough tons of papers! Huh!
Maybe later or maybe these days...it is to cold upstairs in my workshop!

Anyway...this pcb shows enough by now...

[ivconic]

Trying again, this time to use monitor backlight!

In background there is my previous post....which one is better!? Hmmm...
The first one is better ("light bulb" version!! )

I just discovered "poor man scanner"!!! Yup!!

[ivconic]

Small correction;
it is obvious (looking at pcb traces) that used opamp is single one - not dual opamap. So it can't be TLC272 but TLC271 or simillar....
Orbit can correct me if i am wrong...

Abusive posts deleted!

Please calm down everyone!

I have deleted all the abusive posts, starting from the point where things started to get ugly.

Try to stay focused on technical discussions and quit the squabbling. Neither Carl or I have the time or inclination to closely moderate this forum.

I never was riled up! I couldn't understand the Serbian!

I haven't been following the thread closely and got lost myself. I'd like to see a final schematic/pcb as it has become a long thread at this point
