Hi Michal

What did you do with Miner-4?

If it is OK I repeat that please write about:

1.Deep of miner-4?

2.Calibrating & tuning of this circuit?

3.Difference between metals?

4.Everything you think

Good luck.

Hi,

my answers:

1. 1euro coin max. 32cm as iron and 28-29cm as non-iron (color)

2. I replace AD8055 and TL081 with MAX410 - more stability and more deep

3. ok, only BIG iron sometimes as color (non-iron)

4. no need any changes, only value R5 is need change according to coil

Very thanks Michal.

Please write about max deep of Miner-4?

I couldn't find somethings : HCPL3120 , ADS7816 , DAC7611 , TEL2-2421 ,

TEL3-2011.Suggest me to use other things ,please.

Best wishes.

Please write about max deep of Miner-4? - I don´t know cca 1m horseshoe

HCPL3120 - i use HPCL3120 www.gme.cz

ADS7816 - I use ADS7816 can be MCP3201

DAC7611 - I use DAC7611 - i can´t find equivalent, maybe any MAX of MAXIM-ic

TEL - I use three pieces PT4243A PT4243C PT4243N as Free Sample from TI

More: no need use small coil. Without small c. is same with small c. (reaction of small object)

Most need keep resistance of coil between 2 and 2.5Ohms. My coil is 2.1Ohm

P.S. Yesterday i tested Miner with simly big coil (dia. cca 1m) and detect shovel at distance cca 2m

من دنبال یه فلز یاب قوی میگشتم ومیگردم دراین رابطه من مدار پالس 2 گری را ساختم که ای سی7660 ان میسوزد حال از شما کمک میخاهم هم در مورد مدار هم اگه مداره قویی دارید از من دریغ نکنید

[mohsen65]

i need pcb/ part list/shemetic/ metal detector deepers

Miner-4

Hi guys,

I've made Miner-4. Its disc dosn't work properly... Only disc-1 works OK which is not good for me. In that setting only the pure golds can be detected. If the gold be alloyed then it will be showed as FE.

ms.nomi,
Does your Miner work proper at the disc settings 2, 3, 4 and 5?

Best regards,

سلام محسن
اين سايت مدارات خوبي دارد كه من با دوستانم چندتايي از انها را ساختيم بد نبودند ولي قبل از ان بهتر مشخصات دستگاه مورد نظرت را بدوني اما دستگاهي كه ساخته اي دستگاه خوبي نيست وخيلي ضعيف كار ميكنه و مهمتر اينكه تفكيك نداره

hello
any body here pcb and file the program for miner complete here ??
