Who here does science at home, for fun?
I've been an electronics tinkerer for a while, but I've only recently gotten into reproducing some interesting physics phenomena, like accelerating small screws with electromagnets and varying the current, voltage, and substances involved to optimize the acceleration. It's fun stuff, but I'm looking to get a vacuum pump and some good vacuum equipment so that I can create a similar experiment on a higher level of energy: "cathode rays", or accelerating electrons produced by thermionic emission. This is like the mechanism powering old televisions and computer monitors, but I hope to set the system up so that it's easy enough to add additional electromagnets to focus or deflect the beam.
What interesting phenomena have y'all replicated? How did it go? Do you feel that you learned something? Have you published anything on the topic?
