Any one ever use a sound card + software as an oscillscope?
I just want to know how i can make a probe to use as an oscillscope probe that can be plugged into the Input of a sound card.

Thanks

For audio frequencies, the probe from a multimeter will be fine. That is to say, a piece of wire will do. However, at radio frequencies, you would require a good oscilloscope with some decent probes. But for a sound card and some software, 2 wires will be sufficient.

It would but that damn scopes are so expensive.

I got an O-scope about a month ago from www.testequipmentdepot.com.[/url] It does everything I need for my piddling and the price wasn't too bad. [url]http://www.testequipmentdepot.com/instek/oscilloscopes/gos-620.htm[/URL]

What I don't get is why protoboards are so expensive. :( Mine burned up last night right when I'm trying to work on my final project for instrumentation class too. It was very old.
