A bigger bang for your buck
Years ago when I worked on avionics we had a shiny new box delivered to the lab which needed to be tested before it was installed on an aircraft. It was bespoke and very expensive and so shiny that it attracted the attention of a project manager. He decided to start it up while we were at lunch and got busy sorting out power and data connections. We arrived back just as he switched on the power. There was a really loud bang and the room filled with magic smoke. The PM ran past us looking like the coyote trying to catch the road runner.
We were puzzled by the big bang, then someone checked the laboratory PSU. Voltage correctly set to 115V, but oh dear frequency set to 40Hz not 400Hz. Someone didn't understand the use of the decade switch. The manufacturer refused to replace it under warranty.
