In the photo there is one arm of a machine that will rotate a jar on itself. If the jar contains an abrasive, sand or something like that, it will serve to remove the rust from a screw or a coin, for example. If it contains sawdust, it will serve to polish that screw or that coin.

Hello, please make a project of a GPS tracker that could transmit coordinates by SMS, also with a buzer that can be activated by an SMS command and turned off with a button on the device and a small display that would display the number of satellites and a cellular signal, many owners of quadcopters and other flying models would be very grateful to you!
