 +A simple and easy USB soundcard hack for an Oscilloscope.\\
 +But please be careful, no protection is build in. Input signals up to 5V should be save.\\

-Or build a protection circuit like that one:\\ +Use a cheap USB soundcard. Open the housing and solder a wire to the ground and the signal pin.\\

 +Close the housing, that's it.\\ 
 +A decoupling capacitor and a potentiometer to attenuate the signal would be useful, too.\\
