TESORO GOLDEN SABRE

[Max]

Hi,
Yes, I have a good 2-channel oscilloscope.
my phase shift between TX/RX is not big,i had forgot the exactly value.
Now my machine have another question:
In disc mode, it seems have't discriminabilit,
and when working how many current your machine consume.
my machine is about 40MA. I use a 12V battery.

Hi,
I don't remember exaclty now... but consumption with no sound is probably like yours around 40mA or something less. With sound the consumption rise twice or more (depends on speaker and other stuff like darlington used etc) and can be higher than 100mA.

This with speaker... with headphones you have maybe 10mA more only (also this depends on headphones... good ones need really low currents and works nice on TGS).

Kind regards,
Max

hi to everybody. i built a tgs and i have something to ask you guys. i saw a video clip on youtube about someone who is testing tgs with different metels. now, i dont get the sound like that, and i was wondering could anybody else go and see the clip and tell me if i should have the sound like that. thx in advance. and i also think that something is wrong with my detector cause i can remove 90% of ic"s and it wont make any difference. i wound a dd coil 22 cm in diameter 100 and 105 wounds, is that correct?

Hi,
Ivconic posted informations about coil data: 100/105 is good ratio for TGS... find also a way to wound like in old pictures... with nails etc.

Finished coil is under 11' diameter DD, with very good null required.

I don't know about this video on youtube... so cannot answer you about sound you heard.

Kind regards,
Max

yes, that"s the video. should i have the sound like this.does anybody gets the sound like that? anybody?

Hi,
the sound is different on this than on mine !

I think the guy used some buzzer stuff instead of normal speaker!

But I can hear clear there's too much instability there !

It works... but mine is more quiet and sound on mine is more "clear" tone... not buzz-buzz like an hornet flying around.

Maybe the guy had thought about low sound produced by normal speaker and added some extra stuff... like the buzzer thing...

Also from sound... it seems old electromechanical buzzer kind ... like you can find in some old meters.

I think it's not good there... too noise on supply rail... sure TGS don't need this.

Kind regards,
Max

No, sound on video is not good at all. It is doubling all the time, even on a very weak signals. This mean only one thing here; some of coils is reversed.
Looks interesting in air (pseudo rich tone) but on soil it will give so much problems and falses....

[gagi_pirot]

ok. thanxs a lot all of ya. you clear my mind. my result are about 20+ cm with 1 dinar (20mm) coin, and i am not satisfied because i have a lot of false signals, my coil is awfull. Ill try to do it like i supposed to, then ll publish my best results. And i am not sure that the electronic is working 100%, at least in my case. per example i got from supplier lm308n and 308an, and when i change its sides i wont work at all. i just want to add that i draw a pcb at first and it didnt work, than i try with the photo system one time and again after that, and i hit the wall in any possible part. i will aprishiate any suggest about my future work, like where i should pay more intention.
im sorry for bugging you guys, i hope you will not understand it bad.

i am thinking of building a serbian most wanted in my spare time, and i heard that it have a intention error in it, and i will be very happy if someone have the correctdata required.

im very glad that i partipate in this project, and im am all shaking for getting out on a field for the first time. i put a lot of my time into it, and i"m doing it mostly for love for the nature and the historic culture

!!!!

"Serbian most wanted".......... Don't lost your time !!!

Ask "ivconic" !

[gagi_pirot]

its me again. i got 25 cm with 20 mm coin, a deodorant spray about 50 cm, but without faradey. does anybody know where can i find a foil for shielding. i tried before with kitchen foil earlier, and i read on this forum that it is too thick. what you guys used? ill take a picture and post it here very soon, as long you dont get the heart attack with my sloppyness.

[gagi_pirot]

i dont know why it screams when i touch it, even on cable, and when i blow in coil it react also, maybe couse the coil aint finished yet?

alu foil(aluminijumska folija)

"gagi_pirot"


Za dan ili 2 ,mozda cu moci da ti pomognem u vezi aluminijumske folije.

Pozdrav !

za carlos x,
vazi, ako ispadne da mozes ti pomozi, svaka pomoc bi mi dobro dosla

[ivconic]

Gagi, wish you success with that! I think you should constrain those bulky wires togather. Might reduce some noise there.

Gagi izvini sto se pravim englez, ali primetio sam negativne komentare kad god neko napise ceo post na maternjem jeziku. Jbga, moram postovati forum i clanove na njemu.
Prvo, moras staviti faradejev kavez na namotaje jer testovi bez toga nisu merodavni.
Drugo, zaista si mnogo "rascupao" zice na sve strane.Taj detektor je namcorast i hoce da sakuplja razne sumove i interference ako zice nisu kratke i ako nisu lepo slozene. A gde ima dosta suma tu ima i lose detekcije.
Trece..sonda,sonda i samo sonda... moras precizno da namotas sondu da namotaju imaju tacne induktivnosti, a narocito precizno da nulujes namotaje.
Na izvodima RX namotaja moras imati sto manji indukovani napon. Tesko i pipavo ali izvodljivo.
Za opsirnije komentare mozemo kontaktirati preko Skype-a. Posalji mi na mail tvoj nick na SKype-u i ja cu te naci.
Pozdrav!

za ivconica
evo jednog mog starog projekta, trenutno u pauzi. posto sam video na nekim ranijim postovima neku sliku koju si postavio. jel si ti pravio bugati? video sam takav, cak imam i sliku sa takvom replikom snimnjenom na parkingu kod sajma u bgu pre neku god.
