For several years, I had a couple of brand new, boxed CD drives sitting on a shelf in my office. Yes, CD drives, not DVD. They were once white, but more recently beige. They were completely useless.
Until today, when I finally needed one for a short project. I pulled it out of it’s plastic wrapping, hooked it up, and powered on.
There was a prompt ‘BANG’, followed by some smoke, and an expletive.
It’s not very often that a piece of electronics explodes, but capacitors do occasionally surprise us with their propensity for pyrotechnics.
