First proper one was on my bachelors project. It was a specific control algorithm for a non linear system. We were supposed to get into the lab so I could test my algorithm and measure the data, but the coof cucked those plans.
The presentation went really well though. Presented my stuff, got really excited about the noise rejection and hysteresis stuff.
Only snafu was going full autismo on the conclusion slide. Went full spaghetti, stammered for half a minute and said end of presentation.
I did some lecturing this year, and covered some neural net stuff with first and second year students. It was comfy and I got paid money.
None of my stuff was assessed, it was the academic equivalent of the teacher putting a movie on. But all the students seemed happy to learn about something relevant.
