Since I have kiddos in a biology class I get to geek out a bit and play around with microscopes.  When I was a kid, I received a microscope and thought it was the coolest thing.  Today's microscopes are so much better, it is actually fun!

I found a 5MP USB camera on Amazon to connect up to the eye piece and was able to get it working under VLC in Linux which is really awesome.  If I wanted to I could now stream from the camera through OBS to one of the streaming sites.  How cool is technology today?
