Electronic Battleship with a twist
Senseless Destruction but Fun: source: https://www.youtube.com/watch?v=_bdp9nk0NZk I never would have thought of this idea. Now I have (like most experimenters) accidentally connected power backwards. The center ground pin on a coaxial power connector was the culprit when I popped the big electrolytic in my old Koss amplified computer speakers (I should have used the wall wart !). What an amazing stink was discovered ! Yuck, hopefully whatever gas is released doesn't cause disease :) Now I routinely incorporate some kind of reverse polarity protection circuitry into any project. The only willful destruction of electronics that I recall participating in was using a tube tester in the Nicolet Radio Club to "supernova" the filaments of innocent vacuum tubes :) What a waste - it got old rapidly though.
