    Can Anyone help with a schematic of a PC Osciloscope which does not directly use the sound card?? It can use the soundcard through a Op-amp or buffer so that the card won't blow up if something goes wrong... I hope it to have a DC and AC testing capability of around 50v.. A serial or parallel port option other than sound card input would also do fine..

    There are other ways, but they cost $$$. The sound card is a built in ADC, though limited. I did a search out there a while back, there is everything from USB to printer port, but they are not free (cheaper than an oscilloscope, but everything is relative).

    If you feel real adventerous I've got a design I've been meaning to finish forever...
