at this stage

i want to make lcd for this and i want use turkey site ( i download this file )

KT315 we need your help..

My question is the following..

YOUR show a figure with three points, during a test with different coil change this curve the UP or DOWN. This comes from the resistance overthrow, How should eventually be set correctly HER 1 .2 the 3..


I mean without goals in coil.

ok after having you prefer BULGARIAN ok...
but before fine-tune the YOU pcb , it would be good to look at drive I showed you in previous post.. ??

the signal is rectangular, or in another terminology a digital. a digital signal may be noised, this is not so all important as for faint analog signals. MOSFET will be open or close no matter would be the control signal is noised or not noised.

hi all

Does any one know why Jap is absent? I hope he's fine.

pot pattern with 5 mount holes as I present it like more universal for different types of pots.

hi GS, I agree with you. but I only copy bulgarian design. it was been tested and working good. despite on long length of some traces DP is steady.

hello kt315..
studied briefly YOU pcb , I did not like the distance from the 556 pin 9 toward mosfet , considers it very far, this can be a disadvantage..
MY opinion, is the 556 As close as possible to mosfet a city with good shielding..

any one know about the max depth in soil by 1m*1m coil(more 3.5meters or no?)(maybe Mr kt315 know!!!)
regards

in water the depth is 5meter with 120cm*120cm coil, some one wrote here

[kt315]

any your suggestions on pots' type? what type you would like to use?

Hi KT315,

It is great to see your reply. I will follow your advise and post the results here.

Thanks

try to choice another place and position of the coil in your room. I found only one place in my room DP does not give the noise - on window in vertical position suspended in middle of the window. DP is a clear non-motion very sensitive detector and any interference will give you a signal.

Dear Gurus,

I have constructed DP2 using the Turkish one sided PCB. Unfortunately it is not working as expected. The problem is... it makes lots of noises when kept in Auto tune mode ( I remember KT315 has posted a link of youtube video in which the DP makes all sorts of noises ( my detector is also behaving almost the similar way). But when kept in Manual mode it goes silent. No changes in reaction (silence) when the coil is connected or not connected. I am sure some of you could guess the reason for this behaviour.

My coil is 20 cm diameter .55mm enamel coated wire (.50 without enamel) 36 turns and 2.8 ohms.
