Welcome!

The purpose of this wiki is to release the documentation of my projects which might otherwise stay cooped up in my logbooks and stay hidden or get erased from whiteboards. It is my effort to release my free time research to the world that others might benefit or use it in some way. Dead or blank links are projects that were lost in a 2013 wiki hack.

Hopefully you will find something useful out of this online and open engineering notebook!
