metal locator

4016 = 4066

Looks similar as C-scope minidetector with few vaiants...

Please take better pics with digital camera!

hi esteban i shooted this picture my mobile nokia 5200 if you need more clearance i will be send more image dont worry there are ic 4016bcn ( po136sd)

[detectoman]

very thanks brother rajesh, i think esteban can make the schematics conclusions, too think esteban know the earlier circuit amplifier whit big ics, and amplifier ic, and can give us the tips
i see you old circuit can be been repair, is very simple, members here can give indications
best regards

[detectoman]

rajesh: i see too, the first page, thanks for you great sforces, i think it is very clear, too need esteban conclusions help, then i go to build these, then i inform if have advances on future experimentations
very much thanks brodhy rajesh

hi detectoman coil winding has been damage i can not check resistance there are near about 36awg 7 inch dia meter tx 50 turn and rx 80 turn if you want any help wellcom......

brother rajesk thanks for your big sforces, i think your coil only is move in the position central null, i see these not was glued, then these go move, whit shocks, and is out of right calibrations, other you can repair these if rain oxide and croos in short circuit, due to oxidation, only put others wires same turns same diameter and move the central part to put normal null function, is easy, after fixe whit little cap of wood glue, for posterior adjust, ok you can repair easy these md
best whises and thanks of new

hi detectoman you see these winding is not orignal winding. this made by me orignal winding was very thin wire strong glued with araldite and wraped alluminium foil when i remooved coil cover wire has broken with circuit last year ........ actually i dont knowe how do this circuit work i need a schematic..

Hi Rajesh,

You already have everything you need to back-engineer this design. It's quite a simple design and should not take you very long.

rajesh: if original coil is loss outdoors, i think these md should work too whit same coil of tsglight of ivconic, this is in other tread forum of here, or try whit simple double 0 coils, tx lees turns rx one little most turns, read here, is easy, but if circuit is wrong, this is other historie, rajesh, what happen whit original coil? eat the rats?

hi detecto man i found many object at highly deep it's worked good

hi detecto man i found many object at highly deep it's worked good

Hi Rajesh,
I suppose it's an off-resonance MD. I don't know what do you mean for medium sized object so what about coin detection... say a 23 or 25mm diameter coin (copper , silver or steel etc you can try) ? What's detection in air and in average soil ?

I ask you cause I know (very old) designs that were capable of far detection on the air on cigarette box size things but failed on soil cause of many false signals. I was similar, foil wrapped coils and some digital ic.

Kind regards,
Max

Max, yo dissapear of the forum for some months. What happens... if you can tell us...

[Esteban]

Rajesh

Do you can make better pics with digital camera? Do you can trace the transmitter schematic?

Hi Esteban,
yes right, I was missing in action for a while...

Well, yes, something personal happened... my father passed away and so I think you can imagine which kind of troubles...unfortunately.
You know, people die... sure... I know too...and saw many also... it's life! but sometimes things are not so "easy".

So that's main reason but there are also other reasons that keep me out of games for a while but... sure... not as serious as the above.

Anyway, as said, all that's life, all we know that.

Kind regards,
Max
