Hey! I just stumbpled upoon this website! You can use your sound card as an osciloscope! I feel pretty silly for not thinking about it... But anyway, you can download windows version for free, there is a link on that website.

Also, if there is any linux programmer here, I'm thinking to make similar program for linux.

Thanks for the link to the Scope web site...

Really neat...

Is the process used [here] (http://wiki.laptop.org/go/Making_XO_sensors/How_to_connect_sensors), as regards the audio jack, the same process needed to make a probe for the pc based oscilloscope mentioned above?
