Science hobbyists of Tildes

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?

    Well, I still have my Vectrex :) Maybe it would be fun to try to build a clone? The Teensy forums are kind of neat because sometimes scientists post about using them to build stuff. Here is one...

      Woah, you have a vectrex? So cool!

        Yeah, when I was a kid I got one for my birthday, along with a bunch of games. (This was after it was discontinued and the local department store had a clearance sale.)

          That's so incredibly cool!
