2 boxxxx :)

hola nelson!

hola nelson, mira la barra intermedia, me equivoque, en un metro creo que es demasiado, hazla de 90 cms o menos creo que es mejor que entierres tu mismo un ring de hierro de llanta de auto de medida 14 o 15" en diametro, a un metro de profundidad y que alli pruebes el detector, y asi le das la medida mas conveniente para ti, y para lo que quieres buscar, pero si quieres que tu dos cajas penetre mas, pues lo habres un poco mas, mas no creo que haya tesoros civiles muy grandes, o a mucha profundidad, pero ese detector bien hecho, te debe detectar un tanque de 200 lts a dos metros de profundidad, con 80 o 90 cms de largo de barra o mas bien en su medida de los limites de caja a caja , la barra es mejor hecha de madera o de plastico solido , de metal te restara señal o te desviara las señales bastante hacia adelante y eso es perjudicial

un saludo

Hi Kt315,
Wow - those pictures look like unexploded artillery to me. VERY dangerous!!!

The 2 box version is the most innovative I've seen. Could you provide details on the construction of the coils.

Also, does anyone have a PCB of that 2-box the Russians made that I could buy. It would save me lots of time to get one already made up.

Everyone one have a Au filled 2007!

Thanks for Pics,
Goldfinder

Hi Geo and detectoman for your support.
I copied all your information correct and today i ll start the PCB. Few of the components are here and i just need to get some capacitors, the NE5534 and the meter.
KT815 to KT 816 is the same has TIP30 to TIP51 on TO-220 case. For this i have TIP71 that i think will be ok.
For KT315 i got 2N2222.
I ll keep you inform about my work.
Detectoman, thanks for your information related to the distance between coils and wire diameter.
Will keep in contact.
Best regards
Nelson

Hi Nelson. Lets go to see how i can help you.


Good luck

One more question, whats the value for C4. This is label 2H2.
Is this 2.2 pF or what value?

Hi KT315.
For some unknown reason i can get into that web site.
So if you can help me with files i will be very happy.
My email is [email protected]
In advance many thanks to who can help me finish this detector.

Geo, can you tell me the correct value for C4, this is marked 2H2.

Russian marking 2H2 corresponds to 2200 pF.

Thanks for the information to everyone who is helping me with this circuit.
Here i m sending a picture of my TR Locator PCB. It was very easy to made it.

Estimado amigo detectoman, creo que con los consejos entregados voy por buen camino.
Mi pregunta ahora es sobre componentes, ya que las capacidades de 2uF por ejemplo no las puedo ubicar, pero si existen las de 2.2uF. Tambien la de 3300pF, solo tengo de 2200 pF y podría agregar una en paralelo de 1000pF o similar para lograr estar cerca de los valores publicados en el esquematico.
En resumen cres tú que las diferencias de valores minimas me afecten el rendimiento.
Desde ya gracias.
Nelson

My friend detectoman, i think that with all the information given here i m on the way to success.
Mi question is now about components, capacitors like 2uF for example is not here, but i can get 2.2uF. Also 3300pF is not here, but i have 2200pF and i can add another value in parallel to get around 3300pF.
In resume, do you think that minor changes in values can affect the detector performance?
regards
Nelson

mira nelson yo te aconsejo que afirmes bien las conexiones quitables o atornillables de las dos cajas, para que no se mueven, ya que al rozar estas `por ejemplo con hierbas podrian hacer mover la calibracion, entre las dos cajas" la barra manual de enmedio o sea de donde se toma, te recomiendo sea de madera, para mas estabilidad de señales, ya que si pones un tubo de aluminio este te robara parte de la señal y no alcanzaras la misma profundidad, haz un palo de madera mas o menos grueso y cuadrado, no demasiado grueso, le pones en los extremos unas conexiones muy rigidas de metal, y muy firmes y las atornillas a cada caja con dos o tres tornillos ajustables todo esto debe quedar muy rigido, y el ajuste movil de la caja de enfrente muy estable tambien, hazlo todo bastante firme, y veras que te funcionara todo mejor

hi Nelson. you can set up what you have. 2,2-10 uF and 2200-4700pF will be ok and must work. yours.

Hi KT315 and thanks for this important information about the components replacements.
Tomorrow i ll go downtown to get some of the parts that i need.
One more question, on the schematic that you modified, i can see that you replaced U1 LM324 by NE5534 and also add 1N4150, has i undertood this diodes can replaced by 1N4148. The PCB i made, was from sprint layout file, so my question is if i can still using the LM324 (that i have) instead of NE5534.
Regards and many thanks for your help.

With this pcb try the LM324. No problem.
