RELIC HAWK

[tiktak]

Hi,

Hi,
Ivconic.
How are you?
I also think that this are diodes.But have some doubts for left.It might be TR.
According to Bulgarian schematic there are 3 TRs.And if this all are diodes,then on original PCB we have only 3 TRs.
But I am curies about this track?Where should I conect it?Up or down?Do you remember?
Also I still cant understand the wirings under this hugh 1m WIMA.And some ICs.Can you help there too?Other wirings are almost ready.
With some help I will be ready very soon.I am working enough time on this PCB and now have some idea.

A Top-Notch Electronics Engineer that has 20 years design experience , is now running full circuit simulations on our Bulgarian 5 khz RELIC HAWK . I gave him Max's last schematic version on Thanksgiving DAY . I will post results from his work Possibly early Next Year . This may give the Relic Hawk project a big-boost . .............Regards.............Eugene52

Yes I did post this message , and yes I forgot !!! I will try in the next day or so to see whats up . But , the truth is , IT IS A VERY SLOPPY Looking "UNPROFESSIONAL SCHEMATIC", not done by anyone here on Geotech !!!. Maybe we can re-do the schematic again . AND I will call him back .......... Anyway before I Forget , IS there A GEOTECH MEMBER who lives in Rhode Island U.S.A. ???? There was a RELIC HAWK in EXCELLENT COND. WITH ALL COILS AND ACCESSORIES FOR only $375.00 u.s. Dollars WOW on Craigslist.org . IF a Geotech Member bought it , We would have this project done and over with , in 10 minutes !!!!!!!!!!!!..................Eugene52.

Hi,

Hi,
Eugeen.
I am shore that it wont be so easy.
There are many under SMD ICS conections that cant be seen without desoldering them.But who will dare mess with such delicate design.
The Bulgarian schematic is almost 100 % accurate.Trust me.Only minor mistake there.I am still trying to locate.
The parts places and the conections between them are vital.
But without Max it will be much harder to achive clone.

Hello Tiktak , IF the schematic is close to 100% perfect and you still have problems with the oscillation or with your Rx or discriminate circuit , in other words the machine is only working at 20% of its potential . Then you know YOU HAVE A major problem with the PCB layout , because it does not match the layout of the original Relic Hawk ..... The ground or supply voltage "trace path" must be canceling out signal's . If that is not your problem then it is the stupid search-coil !!! This project will get done soon !!!!!! Do not worry , just keep plugging away , Persistance is always REWARDING !!........Any other ideas or comments Please post here !!!.Regards.......Eugene

Hi,

Hi,
Eugeen.
I am almost ready!There is a diferance.
The only one working PCB according Bulgarian schematic is Maxs one.
And the only probleme were detection of iron from big distanse.Its a mistake somewhere obviusly but the device is working good.
But enought talks.I will finish recheking first.But to tell you the true they had opened RH when they made this schematic.
So the work is almost done here buy Max,Ivconic................................
Only small corections needed.I also wanna make better PCB like the original.
But freds is good enough for testing.

Hello Tiktak , Do you remember where the "CORRECT" coil-data is posted on this Forum , for the Relic Hawk "15 inch coil" ???????... ...Thank-you .......Regards....Eugene

RELLIC HAWK

Tiktak , Do not forget That the Relic Hawk might require a search coil with a pre-amp , like this one for the 15 inch Sovereign coil . I wonder if Max or Fred ran simulation's using a Pre-Amp Circuit ?? ............Regards......Eugene

Hi,

Hi,
Eugeen.
Sorry fo dely.I had probles with internet.
So I still dont have right datas to repeat original coil.Like number of turns and wire d.But Ivconic have mesaure the inductance accurate the post is in thread.And I am shore that he will find the right datas when we finish corect PCB dont worry.Here are many TOP INGENEERS too.
And if you read carefull there is no pre-am in search coil.
See you.

[ivconic]

I already posted right datas many times. How many times i should repeat same old post???
Coil doesnt have any electronics inside, not like at Sovereign.

Hello Tiktak , I am working on this Project again. We do have plenty of time left To finish the Relic Hawk , 2012 is not here yet !!!! ...............Regards................Eugene52

hi

hi,
I just found this.
Its outher buxe that goes to coil.
Ivconic,
So:
TX=3.1 ohms
RX=41.3 ohms both with cable.?Right.

I will buy inductance meter very soon.

And about the picture in post 704 I am almost shore now that its TR.Others are BAS16,but this one must be TR.

About the TGSL audiothuning I were asking you in the thread.I meaned the wordrs that unregistred 1 reposted from Fisher 1266 thread.
I can make myself PCB now.But the Idea is yours and I cant get it same way.Sorry that I post this here but I didnt wanned to get involved in their argue.
Thanks

RELIC HAWK

Tiktak , When I start building on Relic Hawk again I will use 2 breadboards , one will have the TX circuit ,audio and battery input section. The other will have RX and Discriminate circuits. Then , if it works great I will make two professional circuit boards........ REMEMBER: The original "RH" used smt surface mount components and now we are designing for through hole , It is a big difference !!! So it is good to test on breadboards first , then spend money on Final-Professional circuit boards.........I hope I have some free time , very soon !!...........Eugene

Hi,

Hi,
Eugeen.
How are you?
This is good idea and maybe you have a point.But I doubt that this will solve the excisting probleme.And at the end you will have Maxs results.
So no big diferance at the end results.Also spoted that ground here is vital.So buy spliting in two PCBs might be even worst!
I think that I found another misstake.And nows the time to finish this PCB and see for myself.
As I remember Max had problems only with disc.And with discriminate big Iron from long distance.So its probale the mistake I just spoted.

[Ultimate_Haze]

I am halfway there too.
Soon we will see

Today I mesured coil of my Minelab Muskeeter Advantage Pro and find maybe something interesting for you. TX 1 mH resistance 2 ohm and RX 15 mH resistance 30,5 ohm. As you can see, very similar to Relic Hawk, but smaller- only 10 inch.Does anybody knows, can it be used instead original coil of Relic Hawk? I think it is much more easy to find Muskeeter coil or some owner of this detector. Ones, when you get coil which work for sure, it will be more easy to tune yours home made Relic Hawk. Wish you a luck.
