DIY Metal Detector (Au,Ag,Fe) for Pc

1. The parameters of the internal iPhone circuits and the headphone jack adapter can also fluctuate, but they stabilize after approximately 2-3 minutes after turning on the signal (therefore, the metal detector must work continuously during the search).

2. The application is designed to connect the simple circuits of a metal detector to an iPhone through the phone’s headphone jack.

3. THE "VERY SIMPLE" METAL DETECTOR IS PERHAPS THE SIMPLEST SCHEME OF AN ACTUAL, WORKING METAL DETECTOR, FOR IT ONLY CONSISTS OF AN LC CIRCUIT AND TWO RESISTORS IF YOU DON'T COUNT IN THE IPHONE :).

4. WHICH MEANS THAT IT'S POSSIBLE TO DETECT THE METAL BY THE NUMBERS (THE FONT SIZE OF WHICH IS REDUCED) ON THE IPHONE'S SCREEN, BUT IT CANNOT BE HEARD OR SEEN IN PERIPHERAL VISION IF NOT LOOKING DIRECTLY AT THE SCREEN.

5. The first scheme (WITHOUT CHIP) is named "Very simple" metal detector (MD1), and the second is "Sensitive" metal detector (MD2).

6. Metal detectors can detect ferrous and non-ferrous metals (including gold and silver) and are able to distinguish between them (with discrimination).

7. The schematics of homemade metal detectors are EXTREMELY SIMPLE and can be made by anyone, even by someone who's never held a soldering iron.

8. Searching using a metal detector isn't as easy as it might seem and might sometimes be deadly.

9. FREE VERSIONS OF METAL DETECTORS ARE LIMITED BY THRESHOLD OF THE SOUND SIGNAL AND THE INDICATOR LIGHT.

10. The numbers shown on the screen are NOT "Target ID" or VDI, like they are on brand metal detectors.

11. After a change in capacity or inductance, on the first start, or when a change in air temperature occurs (for example, when you went outside), you need to enable the search for the resonance frequency.
