hi
i am new to electronics world.
i heard that i can make my pc as oscilliscope by connecting a props to my sound card's mic plug,but if i use this method for high voltages(not very high voltages only 25 volts max.) it will damage my sound card or even my pc.
so please i want a circuit diagram that protects my sound card from damage(reduces the i/p signal voltages)
thanks
