Hi Esteban.
Why you have the coil in the center of box??? are you use coil stimulator???
Also why so long distance between coil and detector???
Is this coil a loop with transformer??
If yes what about the transformer? is it the same 1.8 ... 2 Ohm??

Regards:)

Hi Geo
Where is connected your RX stage if there isn't a receive coil ?

Best Regards

Geo 10-24-2009 12:32 PM
Hi FrancoItaly.
I spoke for post#39. Are you continue to mean for this of for the new.
If you mean the old one, no Rx stage !!!!

Regards:)

No stimulator. Distance is only 12 cm to the box. Is simple coil, no transformer.

Hi Geo
Excuses me, in my post #43 I referred to your instrument at 135 Khz with a receive coil, with a gain of 1000 it's necessary to balanced the receive coil, or the receive coil it is made vwith few turns.

Best Regards

Hi Esteban
Can you tell me if your lrls are also sensible to trees and stones ?

Hi All
In my instrument at 135 Khz I use in the receiver stage this circuit with very high impedance input. The 2 diodes replace resistors great then 100M that are difficult to find. Perhaps the 10M resistor is not necessary but I had this already soldered in the pcb...the OP can be used as amplifier not only buffer.

Best Regards

With "Volta battery disposition" do you mean each coin on the other.... one bronze, one nicel ... etc???

Maybe can be good... I only use bronze small coins.

No, because don't use transmitter, is pure receiver.

hello stevan my congratulations for these new lrl, i too understand what presence near of circuit and coil cause any indesable effect of funcionability, good stratege of you for most efficience, is beauty the design, seems how jirafe, what features have this cacharro stevan?

Max 10-24-2009 06:29 PM
he only use bronze coins...

maybe he's still in the bronze age there! :D

Hi FrancoItaly.
Sorry i made mistake.....about detectors.
But and this detector is a mono Rx coil and also i have another coil to stimulate the Rx coil. Today i changed coils... i made a square 15cm coil with shield. It seems more sensitive... these days when stop to rain i will go to test it..

Regards

detectoman 10-27-2009 03:25 PM
hey estaban, my questions, 1: have this new design build whit only rx the same capacibilites of one lrl ; tx-rx or 2 is whit less power, 3what is range?4 need you very hig power steps of amplification and bateries, and excess of complex complement for control, or is normal stable? what features, what advanteges, what discrimination? 5 is innecesary tx for one good lrl
is good deep capabilites? how many trasistors
in advance thanks

Max 10-27-2009 06:36 PM
Dr. Best beat that hands-down: already got half-a-mile over a coin! :lol:

You guys better change your mind and start build Dr. Best device... it's worth! :rolleyes:

Hi Max.

The Dr.Best device will give us much money:lol:. Sorry... i don't like so much money, so for me it is good the Estebans LRL :lol:

MFD
 
Dear Geo
I 'm looking for a Good MFD.I saw u have a good one!
It is very good that u test it.
Can u send Schematic,PCB and part list for it pls?
Thnak u and Good Luck

I modificate the old I have, but now with preamp. Look shielded cables in input, potentiometer and main PCB input. Also you can try shielding the core or the coil, deppend what you use. I use core and aluminum loop.

Noooo, I'm just 12 years more mature..). something is going on..absorption...maybe the perfect lrl is a simple sensitive receiver that tracks a movement from an existing energy field in front of the receiver.
