In this first special invention, I'll show you how to make a step-by-step metal detector like mine, I will try to make this post usable for all audiences, but it is inevitable that those who have no idea about electronics will not know anything about it. For those interested, it is not a 1000€ detector, it is a detector to entertain yourself building it, however it has nothing to envy to the most mediocre detectors (between 100 and 400€), I spent a total of about 50€, and it gave me enough to buy the materials. to make three detectorsIn addition, in our shop you have all the necessary components to make the board at the best possible price.
The detection depth is not bad either (this does not usually vary much between detectors), it is about 10cm with the smallest coins (1, 2 and 5 cents). So that you can start to get your teeth into it before you start:
