Thanks for the pic, Aaron. I have no idea what a refractor is or what it does...but now I know what it looks like. One of those doorbell cameras.Well, it's here now! I have a few tests, that's how I know I was making my coffee strong. It's going to take some time to write something up, but let me see if I can get a quick shot of it in action...
Whoops, I made perfect coffee!
