Hmmm, that sounds neat. I will have to look through my box of
computer "Guts" and see if I have an old card. Chances are good
though they would be surface mount though wouldn't they?

Chris,
If you decide to jumper the input capacitors on your sound card, you
put your computer at significant risk. In fact, I think I,
personally, would pass on the sound card thing altogether: my computer
is too important to leave to luck (like my not sampling the line
voltage). It might be possible to blow out the input capacitors
pretty easy. Who knows, they might short through rather than blowing
open.
In the scheme of things, that Vellman digital scope isn't all that
expensive. If you don't like it, sell it on eBay for half, or whatever.
Or, put some money with it and look at the BN310 at www.bitscope.com
