Nah. The battery will just run out, and the computer will go to sleep. ;)

The battery is from our camcorder, and they're available in the local
HiFi-store. :)

I think I should know how to do it. :)

How common are those peak meters you're talking about?

Oh, come on! You know what I mean! People rarely use those kind of smileys.
They're too hard to type. ;D
