Oscilloscope from a smartphone

oscilloscope-from-a-smartphone

A good oscilloscope is too expensive equipment for an ordinary electronic amateur, for whom soldering microcircuits and repairing electronics (Ex: Diy metal detectors) is only a hobby. If it is necessary to monitor electrical signals without obtaining extremely accurate results, it is quite possible to do it at home. Such an oscilloscope connects to the smartphone (Oscilloscope from a Android …

Spirit PI wireless metal detector based Arduino

Spirit metal detector Arduino

Spirit pi wireless metal detector based Arduino is an impulse metal detector. This metal detector is based on an Arduino or esp32 micro-controller and a smartphone. this metal detector is easier to assemble although it contains more parts than vlf detectors  like “smart hunter” because we don’t need to adjust the coils and adjust the balance of the coils. In this metal detector …

Pulse Metal Detector on Arduino

Pulse Metal Detector on Arduino

A redesigned version of the well-known impulse metal detector – “Pirate”, but on Arduino. Has good sensitivity even for small coins. Stable regardless of temperature and battery charge. The scheme of  Pulse Metal Detector based  Arduino is simplified as much as possible. Among the shortcomings, one can note the lack of the ability to determine the type of metal. The type can only be …

Metal detector PI Polonese

Metal detector PI Polonaise Pi polonaise metal detector one of detectors which have a number of advantages over detectors working on a different principle. They include a large range, practically the same in the air and in the ground, very good sensitivity and complete insensitivity to changes in soil mineralization. The disadvantage is that it is not possible to discriminate …
