Re: Not IT-related
Ooh, I remember similar deep in the bowls of the Electrical Engineering department. Things that made satisfying bangs when sliding into place, making the unwary jump several feet.
We had one group project which was using a Z80 board to control a motor. We had to design & build interface circuitry and write the control code in assembler.
Our design had a 12v supply going through some beefy MOSFET transistors, controlled by some digital logic which had a separate 5v supply.
One of our group's contribution to the project was uncovering the small flaw in our design. If you switched off the 5v supply first, it ceased it's function of controlling the MOSFETs and allowed the 12v supply to flow freely, causing an unintended excess temperature event and making the magic smoke escape.
