Friends at work I work I have done to my brother bi based on the metal detector circuit LM386 ICL8038 and I wanted to share with you.
Circuit whether those running the trial, but there has not been known. When set to 5 kHz output frequency of the circuit (through the switch) will see the other metals except gold. switch in the other position will not see the other metals except silver.
Circuit to try to be stuck in the ground (yellow egg sticks: D) will strike the earth with one call sooner yards and two bars poured a little water if the soil between the field survey can be more. With TDA2003 also raise the signal outputs from deeper in the soil transfer calls if we can. Unfortunately, few meters away from the following search term I do not know, but it is said that the term of up to 5 meters.
Brass rods used to make calls Visit here for more information about available address.
Plaque ares file with the printed circuit board is different between the print fool you. After removing the plaque thickens the way I’ve printed circuit board. Can press to make friends this way.
