This group thinking was: if we know how hard we throw a ball up in the air, we know how long it takes to come back down, we can use that as the basis of a clock: to measure time! Very satisfying to watch. 🧵👇

Others test the limits of the course to see how elaborate they can make a rather simple concept: by trying to keep this train exactly in position and knowing the voltage / speed relation of the train, this group can calculate the rotation of the big wheel the train sits on. 🧵👇

Some groups choose to make a very good / accurate version of an existing device, such as this tipping bucket rain gauge. 🧵👇

Throwing a football through my lecture room @tudelfttnw.bsky.social. Final demonstrations of 2nd year course " #Design #Engingeering for #Physics Students 2" were a blast! Two hectic hours to test 28 measurement devices that students worked two months on designing and engineering. 🧵👇

en ja, de opening van de eerste post van deze thread is natuurlijk een knipoog naar deze klassieker. 🧵🛑

PS: Fitting for a workshop on rainfall: we did get to experience actual rainfall and very dramatic skies while in Nairobi! 🧵👇
