TESORO GOLDEN SABRE

this's the part i talking about,because i want to know what i say to the seller when i buy it,and how connect it to the circuit (a detailed drawing),plz help

Hello Hazem

what you see is a switch, point 2 selects point 1 or point 3 ...

ApBurg has beat me to it. (Doh I get slow after I've taken 10mg of my favorite sleeping pill.)

The schematic artist has represented a switch with the symbol for a connector.

By the way, you will also see some drawings where potentiometers are also represented with a connector symbol. That can be confusing also.

To explain the switch I refer you to section of an older specimen of the TGS schematic. I added numbers to correspond to the pins in your drawing.

Hi guys
thank u a lot,i always say this forum is really fantastic,thx

[satdaveuk]

Just go into the shop and ask for a single pole 2 way toggle switch to the phisical size of your requirements.

thx,but i wondering about coils nulling,sometimes i see someone say u must nulling when TX only connect with pcb to reach 4mV,and someone say u must find the deep nulling (is that mean 4mV),what i should to do;connect only TX or both coils with pcb for nulling and which point we must check;J1-1 or U101a for nulling,everything is ok except the part of nulling.
u will say go here http://www.geotech1.com/forums/showthread.php?t=15710 i know this but i wanna info from u.
thanks

You are 100% right!
I was the "artist" back than, SORRY!
It was the time when i still learned how to use ExpressSCH...
Sorry again!

It's ApBerg - not ApBurg!

Hazem don't worry; both methods will lead you to properly nulled coil.
It is just a matter of personal choice and habits.
You will not make mistake either way.
Cheers!

Hello Ivica.


I do not mind.... look at the bottle... berenBURG good stuff ..if not to much ...

From the same origin as the coin you see in my avatar.... the place were I was born...long time ago...

Very best Regards.

Ap

p.s. you also have seen the youtube video 'unwilling Blistool' ... sometimes DIY tesoro's have the same ground effect ?? I never found out what the reason was.. static load?

Nice bottle! Promising!

...

Static load... whatever that may be - most probably yes!
I think such behavior appears due not very well optimised circuitry, some component with greater tolerance, some wrong value, maybe some internal loops (pcb, housing etc...)
It is not rare and it is not strictly related only to hand made detector. I've experienced that even with few originals in the past.
Or... maybe some of other guys had hidden jammer in his pocket! How about that?

[hazem]

thanks,will be no problem

..... a nice square wave..... in low modulating freq.............. can be , a friend made a jammer that mobile phone's din't like... So a jammer if you do not like metaldetectors....can be..

But as you write gound loops can also make you go mad, in a Surf PI adding a extra gound wire for external potentiometers made the surf total unuseble !

Best regards!

Hi Ivconic
I maked tgsl with attach pic version
It sensed a small gold coin under 20cm in air and it was low in my mind
I tried to make a 40cm coil for it but i cant reach 16.5 khz on rx
When i tried to reach 16.5 khz ,its inductance was 4.2 mh and my tgsl componnent was over-heating on 22 ohm resistor in speaker section and it burned
I used 0.25 wire for its.
please help me

Thank you

Sorry for not answering, i just saw that this is addressed to me. (Don't have habit to follow these topics on daily bases lately, too much other things to do...)
Small gold ring at ~20cm in air is not that bad result after all.
It is not mandatory you to insist strictly on exact inductances.
4.2 mH yet is too low for TGSL.
40cm coil will not improve nothing at TGSL, Porkluvr is right.
I was most satisfied with 27cm DD as largest for TGSL. 25cm will do also.
Don't expect "meters" with TGSL because it is not designed as that.
Main TGSL advantage is very fine behavior and excellent DISC/GEB features.
But, in case you want to boost it as much as possible; than please visit IGSL topic and see second version with modified TX and TX coil with 1mH inductance. Use that TX on TGSL.
It will need you to make quite different coil and TX setup on it, but it will work just fine with a bit of trimming.

Yes, loops; most probably.
Now you know why i made so much pcb versions for TGSL in the past!
Jammer is a hell of a gadget... in given situations and under given conditions!

Hi
i'm now know everything about TGSL,but i wondering if there any modified on TGSL,i have 7 Jan 2012 Version it is ok?.
thanks

No apology necessary. It's your doggone creation and you can draw it any way you have to. Ummh by the way, a big thanks to you for the project. A major success.

Him not ApBurg? Well, call me pigliver. Yeah, it was late.
