content: While the power to the lab benches is off plug a bunch of electrolytic and tantalum caps into all of the power outlets. Then just wait for the teacher to return and enable the mains power to the benches.-PbFoot

content: hehe.Blowing capacitors up is fun. My old lecturer demonstrated a couple to us a few years back, and we did some with the technician once.May as well blow things up if you get the chance,

content: Well... in my day our "breadboards" were literally rectangles of plywood with various electronic bits stuck to them with spring loaded phansteil clips. You would use bell wire with stripped ends under the terminals to connect things together. Lots of high voltage caps and a transformer with 350V taps on it. One of the things we liked to do was cascade them to get 1kV or so and connect them across the caps. Confetti would rain down from the ceiling...

content: In my university, the lab room must be supervised when students are in attendance.The reason - about three years ago a student managed to kill themselves! Tragic - I guess it must have been a mains shock - everything else is below 30V in the labs. Though I suppose power converters is one module... and boost converters are easy enough to make...

content: My old chief workshop technician, Ron ( he has retired after 38 years as a electronics technician repairing medical equipment ) told me a story of what he did when he was at college studying electronics.One day Ron decided to stuff wire wool between each bench power supply terminals which were connected to a big transformer and centrally switched on. The tutor later switched on the terminals and all the wire wool glowed and smoked! The whole class group was detained for 2 hours until the culprit confessed but it was not even Ron's class group!Decades later Ron's old tutor was a patient in the hospital and Ron got into conversation with him and confessed to that crime! The tutor remembered the prank and admitted that he had no idea who did it until then!
