hi all
I want to make this detector but befor have questions :
1-have discriminations?
2-should i buy the program file for pic , or exist here?
3-lm2930 do not find can i use 7808 ?
4-explain mor about the lcd and programing the pic(can i use skt500 programer)
thanks

1-yes
3-yes, but your battery voltage should be al least 12V if you use 7808

[mohandes]

any body knows about pic program?

[joop]

See the very first post of this tread (by leonardo), it has attachment VDI_02.zip which has schematic and HEX file for PIC16F88.

elbombaci

is this the correct way to wire the encoder
just comparing the drawing with the physical encoder picture
tag #7 looks like the tags on the body

HI
mr 6666 i can not find this pot in my country , what is this name (completely)?
please say me?

Check the offset of the last stages of your LM324. I will bet that it's 5 - 10MV negative. Replacing the LM324 with an LF347 will most likely fix it if that's the case. With a home built 10" coil I can squeeze 19"out of mine for a U.S. Quarter. Problem is, only about the first 12" is usable as it becomes unstable at high sensitivity setting, even with a stock coil.

very good my friend , in your clips are good
many thanks

In post 457 what we are talking about is a rotary encoder, it is not a pot.


inside it there are mechanical switches that operate (open and close) when you push the shaft and turn the shaft,
the switches can be used to make pulses and the pulses can be counted,
if you look at the schematic symbol you will see the switches, is that ok ?

thanks i will check tomorrow
but do you know equivalent for this PIC:
16f690
thanks
(i can not find it in iran)
look this please :

[ossamaussama]

i use cc coil but i lose 6 cm under bad ground

is DD coil better?

[mohandes]

hi all
please see ad avswer








edit :
Can i use coil of cscope metadec for this detector ?
how the connection to the board??
about the PIC not equivalent
thanks

[mohandes]

please tell me

i read to page 60 and finally solve all my problem except some .
GURUs tell me about my ? in the pic please,first Ques for Guru



and this is my cscope coil, can i use it for IDX???




Mr Don
can you help me to make this coil ?please

[mohandes]

again ask ,(maybe any one know, or help)




and can i use this :




or i should have this coils:

i finish my board except VDI(because pic 16f88 and 16f690 isnot my country)
any body can programing VDI by this PICs :http://88.198.55.164/products/category/123/


many thanks and cheers

Been looking at my other permission. Farmland with medieval history, plus Ive discovered a small amount of roman.
The small hammered is edward VII from ~1490AD so fits with the medieval nails and pot thru the post medieval.
Been a great summer with the idx. Ive no idea what the lattice cover plate is, it had 2 fixing holes and looks like a vent cover?

right columm
buckles, crotal bell, rings, (roman button, saxon strap end, late med strap end, thimble), nuremberg jetton/ ed VII penny, Medieval nails.
Column mid
rubbish, crotal bell, crotal bell, crotal bells, (mixed coin, roman, 1695 farthing)
left col
lead washer, mixed lead, buttons, cast pot leg/lead handle pour to fix blade into antler handle, pewter sherd, spindle whorl, loom weights.
lid..
pen knib shape is musket ramrod end guide, dark linear bonze parts - patterned, Unknown.
Lead gun powder measure, plated copper alloy spoon bowl whaetsheaf maker mark with W M, pewter ornate vent?, older crotal bell
pot, clear, black, green, beige glazes..

All of the copper alloy and Iron has been preserved using the microcrystalline wax method.

FLO is gonna have a heart attack using up their pad..
