Hello, welcome to my site! I'm Michael Zarras, an Engineer building things to help solve my problems, or just that I think are cool. I am a marathon runner and have lived with type 1 diabetes for 14 years. This site contains info about all of the things I am currently working on and some other random stuff too.
