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

-Use a cheap USB Soundcard.\\ +{{:linux:usb_soundcard_oscilloscope_175840.jpg?400|}}\\ 
-Or build a protection circuit like that one:\\  +{{:linux:usb_soundcard_oscilloscope_175548.jpg?400|}}\\ 
-[[http://xoscope.sourceforge.net/hardware/hardware.html\\ +Use a cheap USB soundcard. Open the housing and solder a wire to the ground and the signal pin.\\ 
-One can use a 1N4148 diode instead of 1N914 diode.\\+{{:linux:usb_soundcard_oscilloscope_175615.jpg?400|}}\\ 
 +Close the housing, that's i!\\

 +Best use is together with a breadboard 
 +For an simple input protection a decoupling capacitor and a potentiometer to attenuate the signal would be useful, too.\\
