DEEPERS

[Alexismex]

hola Jant nadal,
no falta integrados,
U4a es la mitad de un LF 412 (TL 072) ...Uab es la otra mitad de un LF 412
igual U6a es la mitad de un LF 412 y U6b es la otra mitad de LF 412
El diagrama es completo 100% y original....

all the Ci's are in the schematic .... U4a is LF412 half ci and U4b is the another half...the same for U6a and b...ok you can use also TL 072
genuine 100%
Alexis.

Please Jant Nadal, separate your sentences with a point and start a sentence with a capital letter. If you do not write in upper case the names of your city and your country, that means you not love and not respect them. It is clear that you do not respect participants in this forum demonstrating illiteracy, but at least respect yourself and your nationality.

Por favor, para separar oraciones con un punto y comenzar una oración con una letra mayúscula. Si usted no escribe en mayúsculas el nombre de tu ciudad y tu país, eso significa que no te amo y no respetarlas. Es evidente que de no respetar los participantes en este foro que demuestra el analfabetismo, pero al menos el respeto a sí mismo ya su nacionalidad.

hola alexis por casualidad tu tienes los numeros de todos los circuitos integrados que componen el diagrama del deepers 8 ya que faltan 2 el u4b y el u6b que no estan en el diagrama segun mesy envio el diagrama con dichos circuitos y faltan 3 segun el diagrama que tu enviastes si puedes te lo agradeceria de corazon y si tienes la caracteristica de la bobina hipersensible del deepers seria estupendo un abrazo de jant nadal desde caracas venezuela

Please write in English.

Por favor escriba en inglés.

hola nelson estaria interesado en construir la bobina hipersensitiva del deppers si eres tan amable me podrias enviar el diagrama o fotos de la bobina saludos desde caracas disculpa que no te haya escrito antes solo que no estaba en mi pais estaba en españa y recien llegue.

Translation with Google:

hellow nelson would be interested in building the coil of deppers hypersensitive if you're so nice you could send me the diagram or photos of the coil greetings from Caracas apology that I have not written before that it was only in my country was in Spain and newcomers.

Unfortunately the Google translator can't place dots, commas and uppercase letters when these are not correct in yor writting. Respect the participants in this forum even when writing in your native language.

Hi Alexismex.

I have tested Deepers MF and i think is a good detector, but when you go to a high mineralized ground, it beeps all always. I have tested all kind of setups, but when i got off the beeps, deep range gots short.
This test were made with the Hipersensitive coil.
I also made a 20 centimeters coil, working good, but on high minerlized ground, the same thong happends.
Now i m looking to make a DD coil, but i need information on how to build it and where to connect it to deepers MF.
This week i have to make a desicion if i m going to buy it at a good price or just leave it.
Regards

Nelson

Soon i will post the power supply i must draw from paper to Splan,
I do not have actually a camera...later .
For the performance very good in neutral soil... with 10 inch coil.... air test 85cm .... inside ground 70 cm.for a alu-coca-can ....much much better than pulstar....If you see the schematic ...you will see a small " Deeper-secret" to give the punch for the sensibility ...you must use + 6v and -12v for the Op's.... if you go to a more conservative approach with +5V and -5 V or 6 and 6 you will loose easely 10cm for the alu can and proportional with bigger coil ....
have goods feeling all the forum.

Hi Alexismex.

Do you know how to make a DD coil for Deeperf MF and how to connect to it?
Also do you have any PCB?

In advance many thanks

Regards

Nelson

Hello Nelson ,
The schematic is 100% functional from original ,is my contribution for 2009....

Deepers 8 schematic without comments have a nice day
all the people of the best technical forum for Pi

hello
Deepers scheme ready

Add URL and I will also make pcb.

I wonder who you go out this circuit?

Hi Alexismex.
Last weekend i receved an original Deepers MF (that have all items show on the pictures), that looks the same has the Deppers 8. The only deferent i can see, is that Deepers 8 have an LCD meter. The rest look to me the same.Next weekend i will have time to take many pictures from Deepers MF (10 DD).
By now i think the most important part is to have good details of the pcb traces and components placement.
I don´t think that a conversion from Deepers MF to Deepers 8, will be to much complicated.
By the way i had just an air test with a coke can, and hipersensitive coil, adn results was almost the same you got. Looks like a good machine.
Another function that i did like, was the way you can shift frecuencies, very easy and also helpfull to get te best sensitivity you need for the target you want to find.
Inductance is the same has you, 285 uH and 2 ohms for the hipersensitive coil.
I wil also like to make a smaller coil,that is also easy, cause the coil is a 4 pin standar conector.
Well lets keep in touch to share more informatoion about this detector, that for many peole looks like a mysterie cause the is not to much review information on the net.
Kind regards
Nelson

When i said it is not temperature related i meant a regular MD working in a conventional way shoud not be much influenced by a small soil temperature change.
Soil humidity perhaps, but how much does it change below surface BEFORE sun rising?
And why this MD works better in a wet (or drying) soil than in a a dry one ?

Good question! Most probably because em field reaching more in a medium wet to wet soil.

[Fred]

Wrong! Early in the morning, soils exposed directly to sun are changing temperature very fast. You can see that process through weak steam that appears over soil. It is fast process. 20 minutes after sun appeared, soil is much "different". Of course this is significant only in summertime. Wintertime without snow is best period for prospecting (for me).

[ivconic]

mmm : " when sun is just about to rise",
Strange. Not temperature, not soil humidity as it doesn´t change yet...
Could be IR or UV...or RF from Sun

BTW... I think what Ivconic reported is related to soil/surface conditions... like humidity... though I dubt LRLs have anything to do with REAL MD behaviour...

This is like a bomb in the LRL world ... you have to dig this !

Bomb in LRL world ???

Maybe Dr. Hung has some spare match and dynamite candles to share...
