Yep, it's Fedora on KDE

Yes I did test that too! It seemed to sound a little nicer this way though, more cartoonish

You could, but from my measurements the capacitor tends to pull ~1A before it bursts, so you'd be running up against the 3A limit of USB. At voltages below 12V, they don't seem to go off reliably.

Have you tried a backwards polarity tantalum capacitor? I've seen those go off just on their normal voltage when installed backwards. Sometimes immediately and other times with significant delay.

Eye Projectile and Eye Flash protection along with hearing protection are required.

I wish I could've made it there :/
