    you dont have to make probes...
    you can get them in shops.
    it is actually a thick wire sort of stuff with one input end to be connected to some device. eg. frequency generator, CRO. and the other end has 2 wires- red, black.(+ve,-ve)

    Probe contains specific fibres to send the signals too..
