Perhaps I wasn't specific enough. It's
in the computer. It's so simple! [/Zoolander] If it was simply a matter of plugging into a headphone jack, I would do exactly what you described. Right now I'm considering soldering in a second connection in parallel to the existing headphone jack, though I'd prefer not to physically alter the card, so I'm debating.

I wouldn't need an AC to 5 VDC, since I would be using a computer power supply which has a 5 V rail. However, using a seven segment driver seems unnecessarily complicated for this project... though it's an idea. I'll think on that. Thanks!
